    I have a T250i (Vodafone branded) to unlock and change LP to Portuguese Br. Unlocking ok. Testing phone before flash and phone is working. So, go flash phone. All done, but after flash (and unlock again) phone, i had aways "No Network" message. Checking phone´s info screen (press "*" key 3 times without SIM inserted), i´ve found the problem:



    So, flashing it again with second file. Same problem:



    Flashing again with third file, and problem is solved!



    For my language (PT Br), there are 3 flashfiles on Support Area:
    - T258c_T250i_T250a_DPY1013220_8_Generic_Latin_Ameri ca: 850/1900Mhz
    - T258c_T250i_T250a_DPY1013221_8_Generic_Latin_Ameri ca: 850/1900Mhz
    - T258c_T250i_T250a_DPY1013217_15_Generic_Latin_Amer ica: 900/1800Mhz

    So, if you have network problems after flash, check info screen to verify SW network operation band. It must be matching with HW band:



    If band not match, flash it again with a different flashfile. If match and not works, you have HW (or "blacklist") problems.

    q:
    How to service db2010/db2020/pnx5230 cid49/cid50/cid51/cid52/cid53 using setool2 alternative bypass method ?
    what problems i can meet and how to resolve them ?
    what precautions should i follow ?

    a:

    terms:
    phone should work fine.
    red blink, white blink, etc phones are NOT supported.

    you can only use alternative bypass if your phone has supported firmware (you need BOTH rest file and bypass package)
    if your firmware not supported, either flash supported firmware (only main part in enough) or post request on forum.
    note, that you MUST flash firmware in SIGNED MODE.

    please, visit support area to fetch latest bypass packages.

    if you will use USB as interface, then you SHOULD turn phone on and install CSCA(MODEM) drivers.

    if you are capable user, you can edit .inf files of CSCA(MODEM) drivers - we only need to install
    Sony Ericsson Device XXX bus driver and Sony Ericsson Device xxx USB WMC Device Management
    - all other devices is not needed.
    that will help you to save comport numbers.

    important! if your phone had unsupported firmware and you flashed main part (all parts) of supported - you MUST power on phone, so phone will update new firmware info.

    because of way new alternative bypass method works, you need
    TEST SIM card (mcc/mnc 00101) or OPERATOR SIM card. (you must be able browse phone menu,etc)

    supported following models:

    db201x cid50/cid51 - k320,k310,k510,w300,etc
    db2012 cid52 - normal CID52 phones (w200,w300), abnormal CID52 phones (k310,k510,w810,z550)
    db2012 cid53 - normal cid53 phones (w200)
    db2020 cid49/cid51/cid52/cid53 phones
    pnx5230 cid49/cid51/cid52/cid53 phones

    supported operations:
    unlock via patch, all additional things that setool2 can provide.

    YOU AGAIN NEED REST FILES !!!! FOR ALL MODELS, WHICH ARE SUPPORTED FOR ALTBYPASS !!!
    GET THEM FROM SUPPORT SITE OR DO IT YOURSELF


    Procedure of new alternative security bypass :

    1. select correct phone model
    2. go to settings tab,
    3. check BOTH "signed mode (using server)", "enable alternative security bypass", that is required
    4. optionally, check "unlock after flash", "patch otp<>gdfs check in firmware"+"allow to change IMEI when unlocking" (read precautions)
    5. optionally, check "complete phone after flash" (i recommend to use custpacks)
    6. go back to semc tab
    7. if you need, add main+fsimage+custpack (script)
    8. press desired operation
    9. when asked, disconnect phone, insert TEST SIM, POWER ON PHONE FULLY and connect again.
    Code:
    when i say "POWER ON FULLY" - i mean state of phone, 
    when it shows main screen with operator name ("no network" with test sim)
    10.
    if you using USB as interface:
    "executor" applet will be run automatically

    if you using COM/UFS as interface:
    in phone menu go to games, find and run "executor" applet.

    phone should enter preloader mode ( will appear as dead )

    11. try to power on phone.
    phone must NOT power on.
    it is OKAY.
    Code:
    If phone power on, go to phone menu->games,
    run "executor" application, go to step 11.
    12. Disconnect phone, remove battery, insert battery, press "READY".

    if you use USB as interface:
    connect phone while holding corresponding button ('C' or '2' for w880).
    notice,that you MUST NOT use "2+5" button combo.

    wait for operation to finish.

    13. turn phone on and check it. delete "executor" from games.

    Code:
    after unlock in phone will be application called "executor"
    (menu->games->executor)
    it is leftover from unlock procedure, you should delete it ... or....
    if you run it - it will install preloader in phone and then you able to do 
    any setool2 function without all that long steps... 
    (just check ONLY "enable alternative security bypass")
     phone will appear as "dead" for user in preloader mode
    approximate time for unlock by patch using new alternative bypass method is 160-180 seconds on one phone.


    precautions:
    please take care that there is NO (at least, i can't get) cid52 firmwares for following db2010 phones: k310,k510,w810,z530,z550.
    because of that if altbypass operation will go wrong for that phones - you should use reset operation in order to fix phone.

    under "go wrong"i mean:
    - terminated flash procedure or anything,which prevents phone from starting up
    - changed IMEI of phone, which prevents phone from using new alternative bypass method.

    possible problems:

    in case of terminated flash/etc you can always return phone to life by flashing any original firmwares into them -
    and then it ready for execution again


    on "step 12" phone not booting, embedded loader not responding in 15 seconds)

    due delicate bypass process such thing is possible, but that happens VERY rare.
    nothing weird happens in that case, all you need to do:

    reflash only main part of firmware in "signed mode" and start from step 1.


    by accident procedure was stopped on "step 10" or user run executor and phone entered preloader mode ("died")

    go to settings, check ONLY "enable alternative security bypass" - now you can do any operation with phone, like unlock/etc.


    if using USB as interface, on step 10 setool2 stucks in loop with message "PHONE NOT READY YET", but phone is turned on okay

    well, better ask SEMC programmers why that happens... anyway - to solve that -
    just press "STOP" ONCE - setool2 will continue procedure.


    if using USB as interface, on step 10 i got message "CAN'T START EXECUTOR,RETRYING..."

    it is okay to have that message if phone not in "normal mode" or starting up. just switch phone to normal mode and wait.


    if using USB as interface, on step 10 i got message "There is NO EXECUTOR in phone !"

    perhaps, there is not space for virus, perhaps other problems inside phone fs.
    just flash phone fully using "signed mode" and repeat desired procedure in "alternative security bypass" mode

    q:
    when i attaching phone using dcu60 i see following messages:

    Code:
    erom_readvar: error reading unit 1/725
    error while reading security units
    SECURITY UNITS CAN'T BE READ !
    DAMAGED FIRMWARE/GDFS OR EMPTY PHONE
    
    or
    
    erom_readvar: error reading unit 1/851
    error while reading security units
    SECURITY UNITS CAN'T BE READ !
    DAMAGED FIRMWARE/GDFS OR EMPTY PHONE
    and process stops,but phone works normally on com/ufs.
    what is root cause and what is solution ?

    A:
    that phone is tampered by dreambox software.

    during their "famous' method of "testpoint bypass", they writing patched erom with own custom loader embedded, patching simlock signature check and ... erasing simlock signature without any reason, which prevents setool2 from making backup.

    i had write a post on their forum, but they too arrogant even to read it.

    fix is extremly simple:

    using com/ufs write next script in SIGNED MODE (check ONLY "USE SIGNED MODE" on settings)

    for db2020:
    Code:
    gdfswrite:0001085144554D4D5944415441
    for db2012:
    Code:
    gdfswrite:0001072544554D4D5944415441
    alas, they custom loader also breaks alternative bypass support using dcu60 cable,
    so you only can use SIGNED MODE with dcu60 after their "testpoint".

    i suggest to use setool2 reset method to put proper erom instead of tampered one.

    q:
    when i flashing/completing/etc phone i got error like
    Code:
    loader startup: executed
    Loader refused to start GDFS services,error is:29
    loader GDFS startup failed, that is fatal
    Elapsed: 734 secs.
    what to do ?

    a:
    that error can be caused by different problems. lets see all of them

    1. user has run "executor" application, which was not deleted after "new altbypass unlock".

    solution -
    select correct model
    on settings check only "use preloader security bypass".
    execute any operation, say : "read flash"

    2. main software somehow has been damaged (cause of free tools, etc)
    solution -
    select correct model
    on settings check only "use signed mode".
    add to firmware area only main part of firmware
    press flash (use com/ufs or dcu60 with "2+5" keys if phone not connecting with "C" )
    after that, phone should show identify normally.

    .... and if not....

    3. gdfs area has been damaged (bad flash ic, firmware error,etc)
    solution -

    a) repair gdfs area with reset procedure
    b) install empty flash chip and do emptyboard fill procedure
    c) change both mcu+flash chip from other phone

    q: i have A2 (db3150) phone, which was unlocked by kukuruzer tool and it is "factory" now, i want to make it "retail", what to do

    a:
    you need setool2 version >=v0.95 for that.

    1. go to a2 tab
    2. select correct model, that is important.
    3. go to settings tab.
    4. mark "use signed mode" , "use alternative security bypass"
    5. go back to a2 tab
    6. set "retail" domain
    7. press unlock
    8. follow program instructions
    9. your phone is converted to "retail" state.

    you do not need credits for that procedure.

    q: how to unlock/repair a2 phone (db3000,db3150,db3210) using altbypass option?
    what problems can i encounter and how to avoid them ? how many credits i need ?

    a:
    you need setool2 version >=v0.95 for that.

    first, you can repair ANY software problems for currently released A2 phones.
    for that, you need to do several simple steps:

    1. go to a2 tab
    2. select correct model, that is important.
    3. go to settings tab.
    4. mark "use signed mode" , "use alternative security bypass", "unlock after flash"
    5. go back to a2 tab
    6. set desired domain ("retail" is best choice)
    7. if you want to flash phone, add neccessary firmwares to firmware area and select correct custpack
    8. if you selected firmwares, press flash, otherwise press unlock.
    9. follow program instructions
    10. your phone is repaired and unlocked (and flashed)

    you do not need credits for that procedure.

    if phone is totally damaged (foreign trim area), you required to write gdfs package from normal phone and make unlock again.

    q: What is filemanager ? how to run it? why i can't read files ?

    a:
    you need setool2 version >=v0.914042 for that.

    filemanager is visual tool to play with files.
    create script (text files) with one string
    Code:
    fsManager:
    and select it in misc edit, then press "write script" button.

    note ! you can check only "signed mode", it will run filemanager fast, but you will not be able to read files, only write.
    in order to read files, you need:

    for db2000,db2010 phones <= cid49 - uncheck ALL settings
    for db2010,db2020,pnx5230 phones <= cid53 - check "use signed mode","use alternative security bypass", "use preloader security bypass"
    for a2 phones (db3150,db3210) <=cid52 - "use signed mode", "use alternative security bypass" and set domain to "r&d" or "factory"

    to rename file/directory press F2 or select "rename" from popup menu
    to delete file/directory press DEL or select "delete" from popup menu
    note, that directory should be empty in order to delete it.
    to write file/directory, drag-and-drop it from windows explorer to desired directory on phone.
    to read file/directory press F5 or select "read" from popup menu.
    note, that files/directory will be save to %setool2%\ph_out directory,existing files overwriting without notice.

    q: i want to service j132 phone, but it not have fastport connector, only minuUSB. what to do ?

    a:
    you need setool2 version >=v0.914042 for that.

    you should create connector yourself: select either ufs or com modification
    1219719_orig.jpg
    (pinout discovered by rockerdongle team)
    please note, that if you will create cable with 3 pins only, you should manually press power on button on phone when program displays "powering..."


    q: for curiosity i have flashed ROM image in my lg ku580/kf75x/kt52x.
    phone goes dead. i unlocked it and it came back to life, but i have no network. what to do ?

    a:
    you need setool2 version >=v0.95 for that.

    you need write gdfs package from working phone.
    just select correct model, add to misc. edit gdfs package and press "write gdfs".

    q: i can not connect lg ku580/lg75x/kt52x/sagem my805c to setool2 with supplied USB cable. phone simple turns on and setool2 don't recognize it.

    a:
    you need setool2 version >=v0.95 for that.

    for LG A2 phones with you should use special service USB cable :
    1222580cy5.jpg

    to connect Sagem A2 phones you need modify USB cable, connect pin 9 with GND via 40K resistor :
    1222583_orig.jpg

    or you can buy ready cable from GPG industries http://forum.gsmhosting.com/vbb/showthread.php?t=613936

    for LG A2 phones with Micro-B USB connector you need standart micro-usb cable and simple trick - in order to enable boot mode,
    connect points DCIO and VPP together (see photo). after you finish working with phone - DISCONNECT points, otherwise battery will be drained in 2-3 hours.

    dcio<>vpp pins for KG757:
    kf757.jpg

    dcio<>vpp pins for CF360
    CF360.jpg

    NOTICE !
    looks like ALL newer LG phones (with microUSB connector) can be put in BOOTROM MODE by HOLDING VOLUME UP while connecting cable.

    (works for gr500,gt500,kf757,etc)

    q: i tried to unlock lg kf75x/kt52x with IMEI "01xxx..." and got weird error,
    phone goes dead. what to do ?

    a:
    you need setool2 version >=v0.915020 for that.

    just unlock phone again - it will be fixed and properly handled.
    but - you must manually enter generated unlock code.
    unlock code can be entered by typing 2945#*750#
    in some cases, it will not work until you flash generic (open) firmware from support area.

    edit:
    from setool2 version >=v0.915025 direct unlock of such units reintroduced, you do not need enter codes manually.


    q: i tried to unlock lg gt500,gt505. unlock process appeared to be okay, but phone dead after that ?
    what to do ?

    a:
    reflash phone with any situable firmware from support.


    q: there is too many bypass options. i'm stuck.

    a:

    here is short cheatlist of different phones and scenarios.

    db2000 cid 16,29,36,37,49

    normal bypass settings state - all unchecked, there is no any special bypass options for that phones.
    if "use signed mode" checked - you can only flash signed (flash file CID/DOMAIN=phone CID/DOMAIN)
    to unlock network locks/repair seczone no settings should be checked.
    if phone has cid 37,49 and EROM is damaged - you need use hardware things to repair.
    to unlock network locks using server "use signed mode" should be checked.
    usercode can be seen in identify output.

    db2001 cid 53

    such asic can only be encountered in pda phones.
    "use signed mode" should be checked
    to unlock network locks "perform full unlock instead of usercode reset" should be checked
    usercode can be seen in identify output
    setool2 can not repair seczone in such phones at all.

    db2010 cid 16,29,36,49

    normal bypass settings state - all unchecked, there is no any special bypass options for that phones.
    if "use signed mode" checked - you can only flash signed (flash file CID/DOMAIN=phone CID/DOMAIN)
    to unlock network locks/repair seczone no settings should be checked.
    if phone has cid 49 and EROM is damaged - you need use hardware things to repair.
    to unlock network locks using server "use signed mode" should be checked.
    usercode can be seen in identify output.

    db2010 cid 50,51,52,53

    "use signed mode" should be checked for RETAIL phones - you can only flash signed (flash file CID/DOMAIN=phone CID/DOMAIN)
    setool2 can not repair seczone for that type of phones without hardware things.
    to unlock network locks using server "use signed mode" AND "perform full unlock instead of usercode reset" should be checked
    usercode can be seen in identify output.

    there is two type of alternative bypass (bypass enables patch unlock, full fs operations, crossCID flash)

    1. using server: should check "use signed mode", "enable alternative security bypass" (will work for cid50,51 only)
    2. using local bypass: should check "use signed mode", "enable alternative security bypass", "enable preloader security bypass"

    db2020 cid 49,51,52,53

    "use signed mode" should be checked for RETAIL phones - you can only flash signed (flash file CID/DOMAIN=phone CID/DOMAIN)
    setool2 can not repair seczone for that type of phones without hardware things.
    to unlock network locks using server "use signed mode" AND "perform full unlock instead of usercode reset" should be checked
    to reset usercode lock you must check "use signed mode" only.

    there is two type of alternative bypass (bypass enables patch unlock, full fs operations, crossCID flash)

    1. using server: should check "use signed mode", "enable alternative security bypass" (will work for cid49,51 only)
    2. using local bypass: should check "use signed mode", "enable alternative security bypass", "enable preloader security bypass"

    db2020 cid 80,81

    not officially released by semc, but kukuruzer tool,using unique hardware device, can be used to create such phones.
    such phones can not be serviced with anything, until CID will be lowered again via kukuruzer tool.

    pnx5230 cid 49,51,52,53

    "use signed mode" should be checked for RETAIL phones - you can only flash signed (flash file CID/DOMAIN=phone CID/DOMAIN)
    setool2 can not repair seczone for that type of phones at all.
    to unlock network locks using server "use signed mode" AND "perform full unlock instead of usercode reset" should be checked
    to reset usercode lock you must check "use signed mode" only.

    there is two type of alternative bypass (bypass enables patch unlock, full fs operations, crossCID flash)

    1. using server: should check "use signed mode", "enable alternative security bypass" (will work for cid49,51 only)
    2. using local bypass: should check "use signed mode", "enable alternative security bypass", "enable preloader security bypass"

    db3150,db3200,db3210,db3350 cid 49,51,52,53

    "use signed mode" should be checked for RETAIL phones - you can only flash signed (flash file CID/DOMAIN=phone CID/DOMAIN)
    to unlock network locks using server "use signed mode" AND "perform full unlock instead of usercode reset" should be checked
    to reset usercode lock you must check "use signed mode" only.

    there is one type of alternative bypass (bypass enables full unlock, full fs operations):

    using local bypass: should check "use signed mode", "enable alternative security bypass"

    db3200,db3210,db3350 cid 80,81

    "use signed mode" should be checked for RETAIL phones - you can only flash signed (flash file CID/DOMAIN=phone CID/DOMAIN)
    to unlock network locks using server "use signed mode" AND "perform full unlock instead of usercode reset" should be checked
    to reset usercode lock you must check "use signed mode" only.

    there is no alternative bypass.

    semc ODM phones

    "enable preloader security bypass" has no effect and must be disabled.

    if "use signed mode" checked - you can use usb interface for some models, can use only signed flashes, can reset usercode and total time.
    if "do full unlock instead user code reset" checked WITH "use signed mode" - you can do network unlock, server account required.
    if "enable alternative security bypass" checked WITH "use signed mode" - you can do network unlock by patch, server account required.
    if "use signed mode" NOT checked - you can make network unlock by patch using security hole, but that security hole is closed in all latest locosto chipset revisions.


    lg3g,sharp cid 17,24,41,42,54 phones

    "use signed mode", "enable alternative security bypass", "enable preloader security bypass" has no effect and must be disabled.

    lg,sagem A2-based cid 54,60,185,186

    "use signed mode" should be enabled (it has no effect for most functions,though)

    q: Phone totally damaged, identify not working, gdfs is corrupted, erom is absent, etc. How to fix it ?

    q: What is RESET feature ?

    a:
    that feature require release >= v0.915043.

    1. make sure you have needed quantity of credits on your account
    2. select proper model
    3. on settings check only "signed mode (using server)"
    4.
    if phone db200x,db201x select COM/UFS as interface.
    if phone is db2020 - you can select COM/UFS/USB as interface.
    5. press "recovery".
    6. if phone hardware okay (flash chip,ram,etc) - phone will be reset to developer status (brown)
    7. on settings uncheck "signed mode (using server)"
    8. staying on "emptyboard fill and repair" write correct gdfs_in_ssw format. step not needed if you unlocking phone or fixing security units !!!
    9. staying on "emptyboard fill and repair" flash correct EROM with CID>=OTP CID.
    10. if step 8,9 okay - just flash phone on usual "semc" tab with any situable firmware.

    Q: what is C902AS firmwares on support ? how to determine if i need them ?

    A:

    C902 New Hardware implementation

    A new C902 hardware was phased in from week 09W16 in production, this new hardware requires new application software and it must be version R3EA038 or later to work.

    Old C902 Hardware has used the following TAC:
    35379702
    35714902
    35879002

    Sony Mobile have released on CSPN/Mechanical a “all in one” application that support part calibration for all products that have calibration requirements; such as proximity sensor, touch, gyroscope calibration etc.

    Sony Mobile Repair Application replaces the old:
    Trouble Shooting Application 1269-2060
    Trouble Shooting Application 1257-2706
    Trouble Shooting Application 1262-6643
    Trouble Shooting Application 1276-8378
    which will not be supported anymore!!
