i9300 imei change semi success [ANSWERED] - GSM-Forum

kl0x · 06-09-2014, 15:59

Hi guys,

I've written the original imei to my s3, after writing it I can make calls and receive sms (the imei still is 0049.. thoug

), if I reboot the phone the imei will be the same (0049..) but I won't be able to get signal again.

It happens to no matter which rom I'm using, it "success" writing the imei, it returns to 0049.. once it reboots.

If I try to read the imei once it's changed (and working) it will stop working, doing a backup does the same (it's 0049.. so no interest).

Hi,

Try to flashing with fullflash (5 files ROM) and then repair imei again.

Best Regards

Will I be able to install the custom ROM I have at this moment and keep the imei? I think I found the best ROM ever and I wouldn't like to lose it..

Not succeded at all, I've done fullflash and device is not detected by dongle with UART cable. I went back to the ROM I had (cyanogenmod) and was able to change the imei and get back to the same situation (if restart lose connection)

I wasn't able yet to do it.

Also, with the last update I can't change it anymore, it just stops working..

Finally I was able to solve it, i installed stock rom from Odin (I9300XXDLIH_I9300PHEDLI1_PHE) and was able to change IMEI that stayed after restart.
