How To Work With Semc Odm Phones

[Faisal_Computer]

basics

semc odm phones divide on two big branch:

obsolete cheap phones,where each phone has own loader and approach
j110,j120,j210,j220,z300,k200,k220,etc

that phones not have anything common with semc structure.

and current generation, so-called S1 phones - they based on ti chipsets, st-ericsson (former philips) chipsets
j132,z320,t250,w302,f305,s312,w100,w150,etc.

that phones has good semc structure: color,cid (aid), signatures,etc.

FLASHING OF SEMC S1-BASED ODM PHONES

1. select correct model
2. use com/ufs/usb as interface
3. check "signed mode"
3. add to firmware area needed firmware files
4. press flash

notes:
some old locosto s1 phones does not support usb as interface

if you want flash brown firmware or readout, step 3 will be:

3. check "signed mode","alternative security bypass"


about SEMC S1 ODM files structure:

1. neptune-based (w302,s302,f305) , ST-Ericsson-based (w100,w150)

firmware contain 3 required parts:
- main (ex: R1BA017_1207_9123_GENERIC_HS_YG_RED.software)
- fs (ex: R1BA017_1207_9132_FS_ADRIATIC_HS_YG_RED.software)
- customization (ex: R6A_F305_CDF_1215_9665__FS__Entel_PCS_CL.software)
you need flash all 3 files to get phone working with desired langugaes.

F305, S302, W302 SW flash should be done without memory card inserted.
If the memory card is inserted during flash the flash can fail.

If you encounter this problem,the phone does not startup correctly after flash, please wait 2-3 minutes
then reinsert the battery and start the phone again.
The phone should now start normally and the SW has been correctly updated.
Please note that the SW is flashed correctly and this will not cause any future startup problem.

2. locosto arima (t250,t280,k330,t303,r300)

contain 2 required parts
- main + language R5CA005_OLGA_ARIMA_AMERICA_2_CXC1251008_RED.softwa re
- customization R7A_CDA102866_307__FS__Movistar_Guatemala.software

3. locosto foxconn (z250,z320,r306,j132)

- main R1BA008_1212_9858_MC_JIALI_RED.software
- icons R1BA011_1211_6339_ICN_JIALI_RED.software
(that files reside in archives like MODELx_FWVER_common.rar)
- fs+language R1BA008_1211_6093_MALAYSIA_JIALI_RED.software
- custpack R9A_R306_CDA_1212_6282__FS__Customized_SG.software

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 that

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 hace j132 phone - j132_ta.ssw
4. press flash

you can use trim area in .bin format to restore trim area, for that add 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,though restore phone original imei first, for that:

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. looks 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 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 fs gone to winds. you need 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.
if you have neptune based phone: 1207-7713_EROM_S1_NEPTUN_HS_SEMC_SIMLOCK_R7A024.sin
if you have locosto based phone, then select situable from:
J132_EROM_S1_LOCOSTO_HS_USB_R5A038_64k.sin
K330_T280_T270_EROM_S1_LOCOSTO_HS_R5A028.sin
R300_R306_T303_S1_LOCOSTO_HS_R5A031_128.SIN
for w395 CXC1250616_EROM_S1_LOCOSTO_HS_USB_FLAFLA_R5A038.si n will do job
T250_CXC1250616_EROM_S1_LOCOSTO_HS_R5A022.sin
