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.

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.

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.

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
