Well, i have a razr maxx and i rooted my phone and did the ICS leak with success! Ics .209! So my friend decided she wanted me to do it on her phone, so i used matt's utility to revert it back to 173, and then proceeded to do the same steps I took to put ICS on mine. It wouldn't work after several tries and decide to just return it back to stock, so she could just wait for the actual OTA update. Phone failed during 173 process, now phone fails during boot process. Any help would be greatly appreciated!
