Hi, I've tried to replace the standard arial.ttf and arial-bold.ttf in system/FONT with a other font but with the same name. That didn't work as planned so I changed it back to the original fonts which I backed up before. The strange thing is, when using the standard theme, the font does not work in settings menu e.g. So I decided to delete the arial and replace it again, but after deleting the phone shut down and now it's stuck at starting up. How do I fix this? Thanks in advance!
