hey everyone got a problem with my mytouch3g
I already had the Cyanogenmod 4.2.15.1 working perfectly fine

then I installed the RC30 mod v1.2
restarted phone and it becomes stuck on splash screen (I have waited 30 min to declare it was stuck)
Restarted again and again still stuck.
I tryed reinstalling CyanogenMod didnt do anything same problem
I wiped my data.
I formatted my microSD(FAT32) its a sandisk but it worked perfect before so im sure its not an SD problem
Now im trying to revert my phone back to cupcake using SAPPIMG.nbh
it loads up reads the image go through and gets stuck updating RADIO_V2 the red progress bar on top is like 99%
any ideas on how to get my phone working again?
