Hello, I have a Samsung Galaxy S10e rooted with Magisk.

​

I downloaded Termux from F-Droid to change my navigation bar color and the phone accidentally added a "J" instead of a number at the end, and when I pressed backspace it press enter instead and then I got in a boot loop.

It is the worst timing possible with other things happening in my life and I was JUST about to make a backup, I have already had to factory reset 5 times and spent so much time setting everything up and lost so much I really can't do it again, I just can't man I can't fucking do this shit again it takes me days to set everything up and I lose so much everytime.

​

​

Please help me on how to fix this without factory reset, I heard it's easy if boot loader is unlocked.I can't enter safe mode as well, it tells me I could either "try again" "erase app data" or "shut off" when I try to enter safe mode.

What does erase app data do? It says I can recover important files if I do it but that's contradicting itself since app data is the important files right? Such as notepads photos etc.

​

Thanks for any help and sorry if this is the wrong subreddit. I had such a good day planned out and everything was improving so well then this shit happened it fucked so many things up...

Also I had turned USB debugging off before this happened and set default USB config to charging phone only, I don't know if that screws me over now. Did it for safety :(
