@MrT10001 thanks. forgot about twrp possibility

@MrT10001 i don't have twrp. only odin. if ubuntu itself haven't installed any recovery then idk if such thing exists

@Moem thought there is a way… heard of recovery mode but somehow couldn't get to it. and installed via odin/fastboot, not installer…

i am a web and game dev, sometimes i really lack some features in default browser (like gyro access, webcrypto apis, etc…).
so yesterday been testing out browsers to install (epiphany/gnome browser, konqueror, falkon, qutebrowser, links2, firefox, etc…) almost installed/tested min browser but phone broke before. ofc chrome/chromium isn't available in repos so couldn't. in between when deinstalling one of browsers (already forgot which one) it alo deinstalled (or otherwise disabled) system virtual keyboard input. and some time later got a huge lag requiring reboot.
my phone from start haven't had proper usb drivers (best i got is percentage of battery) and no data connection this way.
so like right now my phone is unusable cause of login screen requiring keyboard which doesn't exist now. can't connect bluetooth keyboard (the one i have) over on login screen, usb as i said broken, ssh doesn't work on login screen (security). right now from OS best i can do is emergency call… and flashlight from statusbar i keeped on login screen.
phone is samsung m33 (custom build) with ubuntu 20.04 .
any ideas to unbrick except of reflashing OS back via odin and losing all data?
haven't made any backups before testing
