I own a 1st gen (Nov. 2013) Moto G. About a year ago I unlocked the bootloader and rooted it so that I could install a firewall. I haven't "messed around" with any settings otherwise.
If I recall correctly, sometime during the last year an OS update was 'pushed' and my phone had no trouble updating. However, with the most recent OS update (Lollipop 5.1) my phone continuously goes through the installation motions (briefly) but fails to update. I get a message telling me the install/update was unsuccessful.
I thought disabling the firewall before updating might help but it had no effect. I am considering a factory rest but am hesitant to do this. Does anyone out there have any advice on how I could make this update work? I would appreciate it!
Oh, by the way - I have not received any message regarding insufficient memory/space - I have approximately 2.5GB free.
Thanks in advance!
