I've read threw many post b4 posting this. Seems semi common but not able to find any reasons to why it happens so maybe here. Every time I install CM7 I brick my phone ("D2" not D2G) and need to SBF back to 2.3.2 (VRZ_A955_2.3.20_1FF_01.sbf). I'm using 4Zroot to root and clockworks bs to apply the rom but when I get into Clockworks to apply the rom it tells me my rom is "(bad)" or Fails integrity check. I got it to install once but the install had glitches in it like 3g wouldn't work and the home button didn't work at all just made the phone get stuck vibrating. The odd thing about all this I MD5 check the images and they pass every time unless I use a download enhancer*. Most the time if I do get the rom to install I just get stuck at the Motorola screen. PWR+X+Search > clear cache/reset doesn't seem to help either. I've tried Images 2011-8-15, 2011-8-11 & 2011-8-8 2011-8-8 worked once so far. I had to clear all my cache several times to get it to even attempt to load though. Not sure why I need to clear cache so many times to get it to even try to load anything. Steps I used. Install 4zroot > Root Phone > reboot > Launch 4zroot to make sure it worked > Install BS > give BS SU > boot into BS > Clear Cache, Clear Data, Clear Davlik & Clear Battery > install from zip > then the problems all start.Redflea was helping me with trying to get this figured out last night. They were installed 2011-8-15 first try. Spent a good 14 hours trying to fix this. Kept me awake till 0840. One good thing to come from this is I got SBFing down to a art now. Windows and Linux. *download manager did corrupt images twice though I caught them with a MD5 check. I'll keep updating this post till someone follows up with a list of CM7 images I've tried. cm_droid2_full-47.zip Installed w/o failing Integrity check or just saying (bad) result = Bootloop twice then a Droid Maintenance screen (bricked). Re SBFing~ cm_droid2_full-46.zip Installed result = Bootloop twice then a Droid Maintenance screen (bricked). Re SBFing~ again. Maybe CM7 just sucks for Droid 2s' anyone know any other GB builds that might install and have stable releases for the D2?
