I just upgraded my phone from a Milestone X to a Razr Maxx on Alltel. I have flashed my X a million times. So I carefully read your thread on rooting and using roms with your Alltel patches. Well, before I did anything, I did a backup of the stock rom that was successful in safestrap 3.11. I then successfully installed CM10.1 into slot 1 rom. Both stock and CM10 worked just fine. I then downloaded the Razr M with Circle Widgets zip and flashed it on CM10 - slot 1.
Later I decided to flash it on stock, but it was having a "weather not installed error" from the widget and couldn't remove the launcher from settings / app or have the option to change launcher when pressing home screen, so I wanted to remove the launcher with widgets. Couldn't figure it out so I ended up doing a factory reset from within the settings / privacy without touching the internal data. That did not do the trick, so I reset again from settings / privacy, this time wiping internal data. That still didn't work because I still had this launcher, so i went into safestrap 3.11 and wiped caches, factory reset, and system on the stock rom partition, then installed successfully the nandroid backup i did. It booted up, I saw the splash screen, then the safestrap screen.
Then the screen went black and stayed black but the phone was on. For over a half hour, it would briefly vibrate every so often. So I saw on motorola's site to hold down and power for 10-20 seconds to force a reboot. Same thing happens after reboot. So I went back into safestrap and wiped caches, tried again with the same result. Tried again this time wiping all, including internal storage, then restore, then wipe caches again - and retored the backup - same thing. Tried to mount slot 1, but I must have wiped CM10 somewhere in the process. I installed CM10 to slot 1 again and I have no problems booting to that.
My question is, is there someway to restore my stock rom? With my X, I would just run RSD Lite and use a SBF file of the Alltel stock rom, and voila, back to day 1. I see that there is no SBF, but what about this backup I made? It said it was successful when I created it, and shows that it was successfully restored every time. I really want to keep stock, because my experience has been that these roms always seem have issues which lead me back to it (at least with the X).
