Hi, I need to downgrade to 4.2.2 but I can not acces download mode. It just says "download mode" and nothing else happens so I cant flash the .kdz file. I can boot recovery (TWRP). I cant find a working solution anywhere.
Thanks

Turn off the device, press volume up, plug in the cable at the same time, it will enter download mode.

Yes. I had 4.2.2 but I tried ported kitkat. Then I flashed the old recovery, tried to restore the backup and nothing is working. So I need to unroot it but I cannot
get to that mode. What a mystery.

Im not sure if I understand. I was already aware of that guide. Thats why I need to boot "download mode" which I cant. I cant find there the solution. I also cant boot the system.

I just tried to connect flash disk via OTG and the phone does not see it in recovery. In other phone it works. So another way is out. I either need to get the download mode working or push .zip into the phone but I have no idea how since the OTG is not working.
