HOW TO WORK WITH SEMC ODM PHONES

 semc odm phones divide on two big branch:

    1. 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.

    2. and current generation, so-called S1 phones - they based on ti chipsets.
    j132,z320,t250,w302,f305,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)

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)

contains 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

UNLOCKING OF SEMC S1-BASED ODM PHONES

server-based full signature method

1. select correct model
2. on settings, check "signed mode", "do full unlock instead of usercode reset"
3. back to odm tab
4. press unlock

that method can fix damaged security zone.
that method depends of external service, so it can be offline any time.

standalone patch method

1. select correct model
2. uncheck all settings
3. back to odm tab
4. press unlock

note, that such method will work only for old security locosto-based phones.
if you will get error while attempting to do that method - you have new security

phone and should try other methods.

server-based patch method

1. select correct model
2. on settings, check "signed mode", "use alternative security bypass"
3. back to odm tab
4. press unlock

user code reset

1. select correct model
2. on settings, check "signed mode"
3. back to odm tab
4. press unlock

note,that some old firmware not support usercode reset, so if standart code will

not work after reset, reflash phone with latest firmware.

FLASHING OF SEMC ODM PHONES

1. select correct model
2. use com/ufs as interface
3. add to firmware area needed firmware
4. press flash

UNLOCKING OF SEMC ODM PHONES

broadcomm based - z300,j210,j220

---------------------------------------------------------------------------------------------------
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

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.

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.

POSSIBLE PROBLEMS WITH ODM PHONES.

phone hang, can't save photo,etc

1. write repair flash from support area
2. unlock phone
3. flash phone with latest firmware

note, that k200,k220 has two flash ic types, select samsung repair flash if you

flash manu id=0xEC,
select spansion repair flash for all other types.
