[SOLVED][Q] Downgrade possible from 80220H?

[Manneman32]

I just got my LG G2 back from service. There was no warranty involved at all but I still left it with stock. When I got it back i noticed that the phone had been updated to the 80220H firmware. The batterylife is amazing but I miss Cloudy G3....

Is there any possibility to downgrade so I can get root and custom recovery back? Any way to do it with a tool from a PC?

Best regards

Try to root with strump apk or ioroot, install autorec apk for custom recovery and follow the OP instructions to instructions to flash cloudyg3 or whatever.....
To return to stock, download kdz file for our phone model and use LG flash tools, do a factory reset.

Well... Strump wants to "use bruteforce" because the phone isn´t supported, thanx to the 80220H update. Same thing with Towelroot. The question is, do I dare to try it? The agressive methot, I mean.

Use ioroot http://downloads.codefi.re/autoprime/LG/ioroot/ioroot.zip, in sideload method, it works fine.
Enable Developer Mode on the phone and enable USB Debugging.
From the PC, with phone connected in usb , tape adb cmd: adb reboot recovery
The phone reboot in the stock recovery, in the menu go to "Apply update from ADB".
In the PC, extract datroot.zip from ioroot archive (in bts folder), and tape adb cmd : adb sideload datroot.zip.
That's all, enjoy and thank @autoprime and @thecubed

The Bruteforce-method worked... now I installed SuperSU from Play Market and all is good. Is it safe to use Autorec even when I´m on the 80220H update?

My goal is to reflash TWRP 2.8.1.1 and then restore my Nandroid backup (made with TWRP)

No problem with autorec and flashing 2.8.1.1 after, i did it.

Thank you all for the help and support. Root worked and Autorec worked. Now back on my Nandroid backup.
