My phone recently stopped working after applying a font in MIUI, it messed up my whole phone and would only boot when the SDCard was out. I've now only been able to run my phone on the stock ROM with the SDCard working, and not been able to boot any other ROM without errors (black screen when turning on but backlight on buttons light up). I've tried flashing new recoveries, going back to stock and rerooting, reflashing mtd0.img, anything I've seen to try and get it back to normal it's failed. My SDCard is a 16GB MicroSD, I bought it about 2 weeks ago and the phone worked fine, I made it a goldcard also. Would the SDCard be the cause and is there anything I can do to fix it? Thanks.
