Thats alright mate, I've gone back to Tesco 4.3 firmware but wasn't able to obtain the OTA notice after flashing back to Tesco stock 4.3 firmware, but remembered I could use the stock recovery to flash the 4.4.2 update zip found on XDA and now I have Tesco Android KitKat 4.4.2 firmware in place... :D Was a ball of an ache to sort it, eventually!... :P
Okay, so I couldn't get the OTA to work, but I remembered I downloaded the zip format that I mentioned previously and copied that to the Moto G internal SD and went to the stock recovery and flashed that zip to the Moto G and low and behold 4.4.2 is now flashed on my device and running so far so good...
Now, just to be safe, gonna to do another factory reset and re-set up the settings and apps all over again!.. <_<
Jammy Buggers!.. I've yet to receive my OTA notice on my Tesco Moto G with sim-unlocked and UK retail firmware flashed on it!.. :angry: So annoyed that I wished I'd never flashed the firmware on to it!.. :angry2:
