How to Unroot the LG G Flex2 (H955)
So you’ve had enough fun with your LG G Flex2 by rooting it, flashing custom ROMs, and just tinkering around with it in every way imaginable. But, now, sadly, you have a need to get it back to stock.
Whether you need to unroot the LG G Flex2 to send it in for warranty, sell it to someone, or just want to have a clean slate to start all over with it, this is going to be how to do it.
Essentially, we’re going to use LG’s own flashing tool and flash the stock firmware from LG onto the device. This firmware contains the recovery, boot image, stock system image, everything you need to wipe out any changes you’ve made and get it as close to the way it was when you bought it.
I. Before You Begin

Let me know if this helped you in the comments below.
this worked, but i got some errors. i thought i’m stuck in a bootloop, but i didn’t do anything so everything is good.
Hi Denis,
First of all, we’re glad that our procedure helped you!
If you chose the firmware that was for YOUR device, you would never face a boot-loop, but since you already are in one, please do the following:
Get into the recovery mode and factory reset and wipe caches on your device. Then, flash the stock firmware and you shouldn’t have any boot-loops.
Let us know how that works for you!
I am not in a bootloop, i just thought during the flashing process, because there were some errors. Everything is fine.
