I am not having any luck getting SS 5.2 installed and booted up on my phone. I am stuck at the 'M' logo. I am using SPR and I am running SS 5.1 without any problem. I did a fresh install of 5.1 and did not use anything to recover because of the problems with 5.01. Here is what I've done so far. Edit: I am using SPR 0.99_3b and I did see a notable pause when it said it was installing /data. Flashed 5.2 over top of 5.1; rebooted into recovery and then rebooted into Android -- no luck. Wiped /cache; booted into Android -- no luck. Flashed Chevy's 800Mhz medV kernel; rebooted into Android -- no luck. Wiped /data & /cache; flashed 5.2 again; rebooted into Android -- no luck Each time that I let it try and boot up into Android, I would let it sit for about 5 minutes at the 'M' logo before I would pull the battery and then reboot into recovery. My restore works and the phone boots up no problem with 5.1. I had the same problem earlier this week when I wanted to give UD 3.1.1 a try. Is it possible that my phone just does not like this version of Android? Any suggestions would be great.
