Problem with a DualSIM Phone - GSM-Forum

Hello.

I have a problem with a MT6225 dual-SIM dual standby phone.

The phone works fine if I insert only 1 sim (in SIM1 or SIM2) but when I put 2 SIMs at the same time, the phone appears to work well, but when I make a call (with SIM1 or SIM2), after a few seconds it says "Failed".

I make a compelte format and don´t know what to do now...

What do you think?

i think problem in cpu.

But how is possible that SIMs work ok if work only 1 of them, but can't make call if they are both online. The problem is only calling and receiving calls. I can see the phonebook, the phone ask for Pincodes of SIMs... but no calls when 2 SIMs are both online.

So, if problem is CPU, what could I do?

hello!

you said you formated phone. Which phone parts you formatted?
what is main and slave part software versions?

This is the flashfile I extracted of the phone:

X225B_PCB01_GPRS_MT6225_S00.MAUI_06B_W07_12_MP_V51 .BIN

I make a complete format, don't know what do you mean with "what phone parts"?

What do you think infinity?

Is there any possibility that the extracted flash is in any way damaged?

hello!

sorry, this must be single CPU phone. there is no "what phone part".
what IMEIs do you see when typing *#06#?
do they match to IMEI sticker?
