Hi all. I was a moron early on and deleted a bunch of the system files after rooting .901 instead of freezing them. I have no way of knowing how many or which ones but I think the only way to get them back is to restore back to .886. All of the links I've found so far for 886 FXZ have been dead. Would really appreciate some help here as I have been out of the scene for a while and am not sure where to start. Would a fastboost restore work or do I need full stock rom? I've done this stuff before but it's just been a while like I said. My phone was stable on .901 but I did a factory reset thinking I would get back the system apps I deleted so that I could do OTA to .246. System update isn't working either.
