Hello
I rooted my Optimus G F180L and uninstalled some of the preinstalled apps.
Today I got a Software Update for my phone which I downloaded and was about 50 Mb.
When I tried to install it gave me an error that a rooted device couldn't be OTA updated.
Then I removed root from the SuperSu app but it gives me the same error as if it was still rooted.
I'm guessing it is because of uninstalling those apps.
If that's correct now I'd need to return it back to stock which i don't dare to do without being 100% sure I wont mess it up.
Would a factory reset do the work (how to do it?) or do I need to flash the whole stock ROM?
Any help highly appreciated!!

try to factory reset your phone, if that don't work maybe reflash or check with your phone carrier before doing anything else, maybe they haven't received the update yet.

Because when i run stock rom, i could receive OTA updates even while it was rooted :cowboy:

you can use a program like Titanium Backup (it requires root), if you wanna save data of the apps you got installed, if you wanna save contacts you can export them to an xml to storage and copy out, and sms' i personally use "SMS Backup & Restore" from Ritesh Sahu does the job good, as long as you don't got any drafting messages.

hmm, that i never have seen before, but if you want you can download the newest original firmware here: http://lge-phones.org/check-latest-lg-official-firmware

used the site a couple of times myself for my E975 and then flash the whole rom.

because i never had a problem, but maybe it's just different in some countries.

but if you decide to use LG's flashing tool remember to backup your data on your computer, or else they will be lost because LG's tool formats the phone totally.
