The process of flashing .215 (or any ROM) cleans your cache, data and delvik cache during the process, that's probably why you see a difference in phone performance. I've been using the .215 leak and haven't seen any performance enhancement of better battery life...although there could be I guess, I just don't notice it. But I suspect the improved performance you are experiencing is the result of the "cleaning" that took place during the flash to .215. If jmurra is not rooted, then having to do so to get .215 opens up a different set of potential problems if he is not familiar with root and flashing ROMs (although I will admit with the RazrUtility and a custom recovery it is pretty safe). None the less, glad you are liking the increased performance with .215 for what ever the reason.I did the 215 leak update from MattyP in the stickies. Made a huge difference. Mine was beginning to get so slow that I didn't want to even mess with my phone anymore. Did not do an fdr either.
My mistake...I think you are right, no root required to flash the .215 link through stock recovery. To be honest, I'm have a senior moment, I don't remember if I was stock or rooted when I flashed the .215 link, lol...it all gets confusing after awhile.That's all good, but from what I understand, the 215 leak is not rooting. It is just an update that never went out to the masses. I could be wrong.
Yeah, but you make a good point, at least by flashing .215 and NOT doing a factory reset you don't have to worry about loosing all your downloaded apps etc.Haha, I hear ya. Although just an fdr would have done the "cleaning" you speak of. I wanted to try this. Working good so far.
