HOW TO WORK WITH SEMC ODM PHONES

[the_laser]

POSSIBLE PROBLEMS WITH S1 PHONES

damaged trim area , IMEI could not be read, simlocks state "tampered" or "0"

first, we need to restore trim area, for this :

1. select correct model
2. on settings, check "signed mode","enable alternative security bypass"
3. add to firmware area

if you have neptune-based phone - W302_TA.SSW
if you have t280,t303,r306,r300,k330,w205,Tilde phone - R300_TA.SSW
if you have t250 phone - t250_ta.ssw
if you have Z250,z320,t270 phone - z320_ta.ssw
if you have j132 phone - j132_ta.ssw

4. press flash

you can use trim area in .bin format to restore trim area, for this select trim area in misc. edit, check "signed mode","altbypass mode","format gdfs when writing" and press "write gdfs"

now trim area structure restored and phone should be signed with s1 signature server.
it is recommended to restore phone original IMEI first, for this :

1. create text file with contents:

taread:000107D1

2. select proper model, check on settings only "signed mode", select created file in misc. field
3. press "write script", file will be created in form %imei%.txt
4. look at file in notepad, you will see IMEI inside in very simple form, change IMEI to original and save file
5. select changed file in misc. field and again press write script
6. check with identify if you set correct IMEI, repeat 4,5 until success

now you need to unlock phone using signature server, consult corresponding FAQ post for that.

note, that alternative security bypass not available for phones with aid 0004, you can not fix aid004 phone with damaged trim area.

phone simlock okay, not tampered, but phone stucked,slow,rebooting. flashing not help.

most probably, internal file system gone to winds. you need to write fullflash from working phone or write clean file system, then reflash phone
check support area for that files.
please note, that all neptune-based phones can be cured with w302_fullflash,etc (check trim area repair case)
in most cases, alternative security bypass needed for writing fullflash.

note, that alternative security bypass not available for phones with aid 0004.

phone can't be detected at all

semcboot somehow got damaged ( while it is never touched by any process )

procedure to fix:

1. select correct model
2. on settings check "signed mode"
3. add EROM to firmware tab.
