@domubpkm Thanks! I did not manage to install ut tweak tool directly on phone either with click or pkcon.
but manage to install it using clickable from laptop using

clickable install --skip-uninstall

usb-tethering is now working when connected to laptop, with good speed, response time seemed a bit slower than usual but up and down speed better than my s10e (just tried a few times, could be many reasons I guess).

to use UT usb tethering with openwrt I had to use this driver:

opkg install kmod-usb-net-cdc-ncm

wiile my android required this:

opkg install kmod-usb-net-rndis

thought this could be good user for my s10e later were audio is not working anyway

Tried to replicate this at FP4 focal devel 598, but seems like non of those commands works any longer, not sure if it's since focal or something else. Does anyone have an idea how to get usb tethering working on this setup, if possible?

@s710 said in How to revert to Android?:

Okay nevermind. Although the bootloader was already stating "DEVICE STATE - unlocked", and every reboot remindst of the bootloader being unlocked, I had to do fastboot flashing unlock_critical (which would ask again if I wanted to unlock the bootloader), and then the flashing tool for FF4 would run fine.

Android was successfully reinstalled.

Thanks for sharing! This post saved me quite some work.
