I have dual sim Lenovo S650.

PROBLEMS:

DEFAULT SIM SLOT (supports WCDMA and GSM) - works fine only on WCDMA /3G. When I put it on "GSM only" it goes dead - "connection error", "emergency calls only" and all that.

SECOND SIM SLOT (which is GSM only) doesn't work att all.

The sim cards are fine (checked it on other phones).
I also put other sim cards in my phone (and swich them around) => same result - sim 1 only 3G, sim 2 dead

Both of them see the providers but have no signal on gsm/2G mode.

Thanks,

Can you get access to a working phone of the same model?

you'll need the NVRAM backup of a working phone

It's not about your IMEI.
