[Q] Please HELP unable to make calls- No sound in-out after upgrading to JB LT4

[tugrulbey]

Hi all,
Last week I upgraded my Note to new LT4 rom.(s). Couple of days later, my Note was unable to make calls. When I try to make call or receive a call, there is no sound neither from earpiece nor from the speaker. If I reboot the phone I sometimes be able to make some calls with a great noise on the background then it stops.
I re-flashed the rom and flashed other roms even re-flashed LZS roms with all clean install even finally formatted the internal sd card . No change.

Since I can make one-two calls after each reboot I still think it may be a software issue rather than hardware.

All other functions including cell reception, 3G, internet, wireless all working very well but cannot use it to make phone calls.

If you have any suggestions I appriciate.

Best Regards

Update - I installed the stocked LZS Rom but the problem still continues.

have you checked that your IMEI is the correct one? maybe it got corrupted...If that is the issue, should be solved by restoring your EFS backup .

No, I haven't checked. But I don't know my previous IMEI . How am I supposed to know if changed or not? I haven't backed it up. How to restore to original status?

Thanks

Below the battery you have the original IMEI number...if it is changed, then that is the issue. If you don't have a backup of your EFS, I am not sure but you can try to flash the stock rom by selecting EFS in ODIN PC. That is stuff is quite delicate, so I would recommend you to ask Dr. Ketan that he is more familiar with it.

But again, make sure that your imei is fine first. If that is not, then might be a hardware issue..

Thank you for your kind suggestions. I checked and it looks O.K. there is no change on IMEI. Actually I can receive SMS and 3G is working very well, my phone rings if someone calls but cannot talk.
