I unfortunetly managed to make my IMEI NULL. I flashed the B926 china ROM to have a taste of the ICS. I backed up my IMEI using 5irom. I couldn't downgrade, so i rooted the phone, then installed CWM and I finally installed the unbranded ROM of Sebastian404.
My IMEI was NULL, i tried to restore it with the app, restared the phone and nothing was changed. Only the splash screen was changed from the spash screen on the custom rom to the one of the chinease ICS ROM.
I tried to restore the IMEI manually as shown on http://www.modaco.co...t-5irom-folder/, but when I get to step 3, the background opening failes after entering the password.
Is there another solution for me? Can I get it fix via Vodafone?
Thanks in advance.
