| Aug 1, 2012 at 12:54 | comment | added | Hassan | I put PG86IMG.zip on my SD and rebooted to let it "flash", as per that guide. Is this what you mean by flashing the stock ROM? Sorry for my ignorance here! | |

@Hassan a factory reset is not enough, as that only "deletes" the user data (/data partition) and wipes the caches. But rooting changed the /system partition -- which usually is mounted read-only and not supposed to be changed. So its checksum still doesn't match the expectation of the updater, which is why it still refuses. As I wrote above: Flashing the original stock firmware should solve this, which probably includes a factory reset -- the factory reset alone isn't sufficient.

| Aug 1, 2012 at 3:24 | comment | added | Hassan | Okay I rebooted my phone and did a factory reset, and it's still not allowing me to update. I also followed this guide to re-lock the phone, but still no luck. Any idea why it's not working? | |
| Jul 31, 2012 at 20:43 | comment | added | Izzy | Of course -- but to factory defaults. So all your data are lost then. Which is why I placed the hint to Titanium Backup in my answer: Your device is rooted, so you can use this excellent software. It even offers a "migration mode" for critical data (be careful when restoring system stuff like SMS messages, call logs, and the like -- if you do so on a different ROM as you backed them up from (careful! Avoid that when possible, do it when necessary), always have that mode activated. | |
