Ye I would say lost IMEI. Have a read through the guide in the general section for the fixes.

If you were just downgrading to root dont worry, carry on rooting/back up TA/ unlock etc then flash a full .290 (with full battery)

Click to expand...

Click to collapse

yeah just checked the imei is blank

can i now just flash a 4.3 firmware back and hopefully it will appear?

can someone please be a big help and link me to a c6866 2.90 4.3 unbranded uk firmware

fcuking legend man!

thanks for the link bud worked a treat
