2 CPU inside.....
how to format ???
have any idea ??

Hello,

As ordinary: 1st CPU 1st, then, format 2nd CPU (if need), but in most case 1st CPU is enough.

[boedi_w]

how to format the 2nd cpu?
same rx/tx pin out?

and the main problem is...where is the flash file for it?

and READ FULL FLASH is include EEPROM?
because i just curious when i try many flash file did not success, i flash again with the backup file but the phone did not reponse.
first time it can ON but not normal.
now, become dead....:D

[boedi_w]

anyway.....doing flashing need 2nd cpu also or not?
or just detect 1st cpu and do flashing once?

[InfinitySupport]

2nd CPU has separate RX and TX so you need to use another RX and TX, not the same as for CPU1.

Flash files is in Infinity-Box support area. Select flash file depends on CPU type.

If you have flashed phone with it\'s original backup file but phone can not power-on you have a very good reason to check phone hardware, f.e. reball flash and CPU chip.

phone came to me in "restart condition" without cimcard at all, but still can power ON
here is the action i have done.

1.try to flash with file from support area.
and here is the backup from CM module: flash[X225B_PCB01_GPRS_MT6225_S00.BIN]_20080801-150547.B0M
so, i try to find similar flash file. in this case i assume will be like X225B_PCB01_GPRS_MT6225_S00.
and i found at least 6 similar file.

X225B_PCB01_GPRS_MT6225_S00.LBN6802_7_12_1_0T01M12 21_M401A_M__S901-CPU1_16m_En_Ru_Fr_Es_De_Th_Vn_Tr_Ar.B0M
X225B_PCB01_GPRS_MT6225_S00.LBP4T02_07_12_1_0T01M0 924_M510B__16m_Ru_Fr_Es_En_De_Th_Vn_Cn_Tr_Ar_Cn_Ar .B0M
X225B_PCB01_GPRS_MT6225_S00_16m_En_Cn_w_eeprom.B0M
X225B_PCB01_GPRS_MT6225_S00__5310_16m_En_Ru_Fr_Es_ Th_Vn_Cn_Tr_Pt_Ar.B0M
X225B_PCB01_GPRS_MT6225_S00__ZTC__ZT2899_16m_En_Cn .B0M
X225B_PCB01_GPRS_MT6225_S00__ZTC__ZT2988_16m_En_Cn .B0M

already try all of them, but phone now became DEAD.
during the flashing procedure, the phone is "ringing" but flashing done.
i forgot some of them make the phone can turn on, but white screen. i assume this is wrong eeprom or firmware?

2.after flash i try complete format, repair security area
with this action phone also white screen

3.try to flash back with backup. >>>need eeprom too????i dont think so, if i flash with full flash backup???
>>>>before yesterday, phone can turn on after flash with backup,format complete, rep sec area.
but yesterday, not turn on at all.....broken flash chip???


i just curious to know....lets say it is a normal phone without problem. i make mistake flash with wrong firmware.
IF i flash back with the backup file. is it need to do next action like format ffs? rep security area??
or dont need this action????

[InfinitySupport]

You need to open phone and check it\'s hardware, clear water inside, reball flash and CPU chip.

[boedi_w]

already did that.
no water damage inside.
btw, which flash file do you think the perfect one for this phone? :D

[InfinitySupport]

Can\'t give any advice what file is better, just need to try and see results (due to Chinese phone hardware is very different).

btw, did you tried to flash phone with original backup and make format ?
And then try to make 112/emergency call without sim.

[boedi_w]

i already try full flash with backup file.
1.full flash with backup file
2.format complete
3.repair security area

>>>with this action 2 days ago it can power on like before( after 3-10 seconds it restart although without SIM)

after that, i try those 6 flash file 1 by 1.
none is success.
after...i try to flash again with backup file. phone become DEAD.

also i already try format whole flash chip.

[InfinityHelp]

try to write full backup, check battery voltage, power On phone and try to call 112 without SIM card

[boedi_w]

sorry, already did that....

send back to customer now...:D
