MPEG4 P888 SIMB Hang After Repair
 

Hi,
I have a MPEG4 P888, original problem was restarting with or without sim, I found second CPU format safe and them restore imei, but now, second sim had no signal bars and when call comes in to sim b it will not answer, please advise.

hello!

are you sure that you restored Original IMEI?
have you touched first phone part?
what was both phone parts versions?

Hi Infinity,
Thanks for your response, I checked the imei *#06# before formatting to make sure i have the correct imei and wrote this number back after formatting.
I tried to format the first CPU, but it is not formatting in "safe" only in "complete", could this be the problem and if so, how can i solve?

hello!

i would advice to format COMPLETE both phone parts and restore IMEIs.

Hi Infinity,
I'm trying to format COMPLETE the first CPU of this unit, but this is what i'm getting, can you shed some light on this for me:

hello!

both logs are from CPU2.
to start work with CPU1 you must switch to other pinout

Hi Infinity,
Thanks for your continued responses and support, i'm a bit confused, so you tell me, for this model, when i run pinfinder, recognises first CPU in 8:4 this is for 6205, the log I sent you.
When I disable these pins 8:4 and run pinfinder again it recognises 10:6 and this connects me to 6226, so i assume this one is second CPU and format complete and rewrite imei works perfect here.
So, can you tell me where i'm going wrong?

hello!

6205 is second MCU
6226 is first one.

my advice is to format both MCUs and also restore IMEIs in both parts.

Hi Infinity,
I tried formatting CPU 6205 and was not very successful, please see logs above, tell me what elese can i do?

hello!

as i can see- formating pased OK.
what about First MCU logs?

Hi Infinity,
I tried to format Mt6205, but now it's telling me "waring: probably flash chip empty,erased, incorrectly flashed or damaged"....i followed the instructions....but still same message

hello!

if program detects flash chip empty,erased, incorrectly flashed or damaged- then problem went too far to solve this by formatings/IMEI resotring.
you must flash both phone parts with correct flash files

Hi Infinity,
I've got other handsets in this model that are working fine, please confirm, to get flash file i must proceed to read flash from both cpu and the flash independantly?

Hello,

for dual sim/dual CPU models you need to read flash from CPU1 and then from CPU2 so you will have different firmware (flash files) for each CPU.
CPU1 file is bigger, CPU2 file ordinary has less size (less than 50% of CPU1 file).
