hello!

i would advice to write no just any number instead of IMEI, but write some valid IMEI from working set.
first IMEI you can see by typing *#06#
second IMEI you can see on GSM tester or connect infiniy box to CPU2 terminals and read out phone info.
please, write there some Vaild IMEI number, not 55555555555555
and post result

unfortunately i returned the set back to the customer, but any way, i have tried to write correct IMEI [valied IMEI like 350........], for both CPU's, and i got same result, if the customer give it back to me, then i will try another time with [2nd CPU].
thank you for the help any way.

SO PLZ INFINITY MOR EXPLAIN

hello mr. sayedhas!

first, you explane what means "same problem"
which sim card is not working? first or second?
did you check for IMEIs? both correct?
did you try to write new IMEIs to both phone parts?

hi

i have same problem

frist sim emergency mode but second work fine

when i try to manua search i see all network when i try to connect to sim network phone show try again later

i try to flash phone wit flash from support area(flash+epprom)

make repair and repair iemi

also how can i write second iemi

thk

hello!

first CPU operation you doing via pinout for CPU_a
second CPU operation you doing via pinout for CPU_b

i think in your case you just need to set correct (valid) IMEI for both phone parts
try this and reply

can i write the same(valid) imie for both cpu or i can write 2 diffrant imie ?

sometimes its hardware problem.

hello!

i would advice not to write to both parts 1 IMEI.
In some countrys operator is not allowing two same IMEIs to stay in one network.
I will tell more: some country operators block phones where last IMEI check digit is incorrect.
that is why our soft always calculate valid last IMEI check digit

How can i read second cpu, because, i read fullflash the second cpu, after downloading bootloader, phone is always on it self.

may i know where is cpu2 power button?

Thanks

hello!

CPU 2 power button is same as CPU1.

when you booting second MCU phone acts like this:

1. you press power button and hold it.
2. Phone start normaly, you can see "Insert SIM", but you still keep power button pressed!
3. after around 30seconds you will see that program detected second MCU
4. You still keep power button untill software asks to release it

Yes its work, BUT :( :(
