Hey guys, I switched my SD card today and decided to re-root my MyTouch to reflect the missing apps on my phone. The issue here is that after I switched the SD card (after unmounting), the phone reboot and I'm stuck in the MyTouch screen. It's been on that same screen for half an hour now. I downloaded SAPPIMG.nbh and am trying to bring my MyTouch back down to 1.5 but it's giving me a "Signature incorrect" error. My MyTouch is an original and is on the 32B mobo. I had also upgraded the radio to 184.108.40.206.02. Is that an issue? If so, how can I fix it? Please answer asap, thanks!
