I am currently on .215 not rooted or anything. I installed it using Moto recovery from .211. I have had better 4G connectivity and battery just as others have had. However, my 3G reception with the radio upgrade in .215 have been worse. I can deal with .211 using more battery, especially to have better 3G connection in my area. My question is what is the best way to downgrade back to .211 from .215. Should I just download Matt Utility 1.81 and choose option 1? I want to keep my data. Thanks in advance. I have read through many different threads...I just want to make sure I do not brick my phone. Thanks to everyone on this forum...but of much help since I upgraded to the razr maxx from the crapple iphone.
You have to do option 1 to revert to stock .211 from .215, this will, and cannot be avoided, wipe the internal data so backup your apps (microSD is left alone IIRC, so put everything there that you want to save)
