Completely destroyed any OS
a few weeks ago my touch keys below the screen stopped working so I bought y new phone and i started some experiments with the old one. Now I'm not able to boot it. There comes an error message that I installed a developer version - even during the recovery (not working) process.
Sometimes I'm able to get into the boot menu and my question is now - which options do I have? Except the last one - having fun with a hammer...
Is it possible to install a custom ROM that got OnScreen Keys so i dont need the hardkeys anymore?
