Hello, I'm Will. I used MATT's utility to put my RAZR running on .215 (A LOOOONNGGG TIME AGO) And I haven't fixed it back to stock yet to get the JellyBean update. Now however, my phone has been lagging WAY more often than usual. It's starting to frustrate me as it turns small task into frustrating ones (like sending a text quickly after waking the phone). The lag is crazy and the phone runs smoothly 40-50% of the tine now which is poor in my book… I plan on moving to the Note 3 as soon as I get the money and I'm comfortable in knowing that there won't be a "new hotness" coming out right after I get it (I hate when that happens) [BACK ON TOPIC] I'm trying to go back to stock so I can get the JB update on my phone. I thinking this will help with the lag (correct me if I'm wrong). I also want to wipe to cache, but I don't know that much about it, Like will it wipe any data or is that only on Factory Reset?…. I visited this forum: http://www.droidforums.net/forum/droid-razr-support/217843-mattyp-s-215-leak-classroom.html And tried doing step 2, thinking it would bring my back to stock, but when I try to install it in the boot menu it says "installation aborted"…. Some one… I just need help.. I tired of my phone being so slow and I don't think I can wait till I get a Note 3. I need to fix what I have now.
