So I followed this guide here:
Mounting /system partition in read-write mode in Android at Black God
and then this guide here:
How to change fonts in Android without font management tool? at Black God
to install a custom font and now my phone wont boot past the "M" screen. I'm not really sure what to do to revert back to the original font to fix it if this is possible at all. Any help would be greatly appreciated.
(BTW, I didn't use adb to change the fonts, I used a terminal emulator on my phone to rename the files)
