Hello,
I have LG G2 D802 brought from UAE. I accidentally upgraded to KitKat 4.2.2 after I brick my phone when trying to install trwp recovery in my 4.2.2 firmware. As I was eager to root it, I saw a method using IOroot25. It went very well and speruser and busybox are installed. But the recovery was horrible as it is not recognising my internal memory at all, when I tried to flash zip files it is not showing in the sd card and no option for back up also. So I tried to use the trwp manger, after that now when I tried to boot into recovery, only error message comes saying that " certificate error", Otherwise the phone is working very well. I tried to unroot using the flash tools, failed, also tried to downgrade firmwae to 4.2.2. using flash tools, failed. No neww rooting method also appering in any of the LG g2 forum. Kindly anybody can help me to solve this problem.
Thanking You

Downgrade worked for me twice. Just after downgrade, you must perform a factory reset.
Downgrade failed

Thanks for the reply,
I tried downgrade using the Xda thread. When I start upgrade, it goes to LG site and says you have the latest firmware, and it stops there. Can you please send me the details how you downgraded. Remember my 4.4.2 shows it is rooted, I tried to unroot using this thread thttp://lionking853.blogspot.ae/2013/10/how-to-root-and-unroot-lg-g2-all.html.
It also failed
So kindly help me
I want to downgrade urgently

No unroot will work. Only flash back to stock which was as replied above. Do not use the official lg tool. Use the one in the thread above.

I downgraded my g2 f320 l/s from KitKat with the shipped ROM 11g for the f320s via unbrick method here on xda. the ROM seemed to flash fine except that it keeps going into bootloop, and when I hold the volume down and power I get what I assume is the boot loader screen with 3 options all of which are in Korean and none of the will allow me to factory reset or boot into recovery. Any help would be appreciated.
Edit: i flashed the kitkat .kdz file from a post on page 154 of the return to stock forum. If anyone is having the same issue refer to the return to stock forum.

you try to install the firmware with LG Flashtool 1.5 or 1.8 (to use this you can follow the steps in the thread http://forum.xda-developers.com/showthread.php?t=2432476)
With this tool you must search the firmware for your phone in TOT + DLL format (not KDZ). For F320K you can find the v20f at
http://storagecow.eu/Xda/LG%20G2/Stock/Korean%20Models%20Here/KTF%20F320K/TOT%20Method/LGF320K_V20f%20e%20DLL.zip
I have resolved my problem with this tool

After that you MUST "trick" the r&d update tool and lg mobile software to drowngrade to the "newest" firmware version
Hi everyone.
I have 4.4.2 installed manually and now i want to get back the stock rom 4.2.2 because of a big touchscreen problem.
With flash tool, it always stopps at 15% so i have to flash rom with custom recovery.
The device is now unrooted, so i need a method to root KitKat. I tried already with iroot, vroot, kingo root, super one click root but none of them worked.
I need your help, thanks.

I have a question,
About My phone, Before installing Kitkat:
D802 İnternational (Turkey)
after installed Kitkat, a vodafone amblem started to appear every time the phone i turned the phone.
What does it mean?
Which stock firmware, i have to install?
Thanks
there is a link in the OP of that thread leading to 4.2.2 firmwares. Look it up, there is one for Turkish d802 too http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/Turkey/
Just check whether you have 16GB or 32GB version
Root for 4.4.2 is possible - if you flash the stock ROM as a zip file in custom recovery from 4.2.2 (which will be overwritten after the flash)
then you can directly flash the supersu zip:
1. boot into 4.2.2 custom ROM
2. install 4.4.2 zip and don't reboot
3. install supersu zip - don't reboot
4. wipe data, cache and dalvik-cache - then reboot
For zips you can use the forum-search function
There's also a custom boot-partition which enables to stay on the old custom recovery, but that's only made for B-Devices...

I flashed custom rom ( slim saber )..after that I went on and installed stock lollipop via lg flash tool.. I also selected CSE install and it booted without problems.. it doesnt say I`m rooted.. previously I also installed kit kat and it said I was rooted eventhough the phone was brand new.

Someone I helped earlier had the same issue. He reverted to stock using kdz method and his phones said rooted. He was still running stock ROM when he decided to use cse flash. After the flash was complete he booted up and to his amazement all of his files were still there and his root. So what I did was installed the tot and DLL file and restored using the tot method and surel after the flash he wasn't rooted and was on complete stock ROM. Try using the tot method and see if that works.
