Yeah, I just ended up doing that. Basically, whenever I used mass storage mode, it would work but the phone would freeze or reboot half the time after going back to charge only. I would then literally have to reboot anywhere from once or twice, to sometimes a dozen times or more, to get back to a working boot. It'd sit there and freeze after loading the homescreen, or after homescreen and widgets, or within a few minutes of loading homescreen/widgets. Even after wiping data, cache and dalvik cache 7 times each and SBF'ing to official Froyo, then going to Liberty 2.0.1, then going to Liberty .1, then .3. (wiping all 3 7 times each in between each and every one of those upgrades/changes)
It was getting frustrating.
And now...I just wiped everything 4x, SBF'd to Froyo again, and now I just turned my screen off and it turns back on to a black screen which I can't unlock.....none of these problems started until I went to Liberty GB. (except the occasional reboot when entering or leaving mass storage mode on Liberty 2.0.1, but it was always fine after 1 reboot until I used mass storage mode again)
Now, no matter how many times I wipe/SBF/etc., I have these "Liberty GB-introduced" issues even on stock Froyo SBF. I'm getting concerned for the permanent state of my phone, at this point...I thought wiping data, cache and dalvik cache 7x each ensured nothing was leftover?
