no... i was wrong. i restored just the data on my stock GB rom when making the manual updat guide,and it worked fine. as long as you only restore data,it should work. i flashed miniRUU,flshed superuser,restore data,and all my system apps were back that id deleted,along with all the apps and such that were there before
So for example, to install ViperRez over stock ICS, I had to:
1) Restore nandroid
2) Flash viperrez rom in amon ra custom recovery
(it gives you an option during the viperrez install to reboot to bootloader if you are S-ON, but I stupidly ignored this)
3) If your ROM didn't flash a boot image for you, you need to do it through the PH98IMG.zip method. I extracted the viperrez rom zip, found the PH98IMG.zip, placed the PH98IMG.zip on the root of the sdcard, then rebooted into the stock bootloader. It asked me if I wanted to go ahead with the update, I pressed VOL UP for yes.
EDIT: Still getting bootloops when it starts to load the home screen. What do I need to do? I have the boot.img from viperrez, but don't know where to flash that.
i think you were getting bootloops becasue you flsahed viperrez over newts. clear storage prolly worked becasue it wiped out all the personal data that was left over from your newts nandroid.
EDIT2: Tried fastboot flash boot [ROM's boot.img filename here] ; fastboot reboot ; still bootlooping. Scotty? HELP!
im sure you figured it out,but for others that see it,if the boot image is named "boot.img" then the command is simply:
fastboot flash boot boot.img
EDIT3: OK, after I was about ready to give up, I did 'Clear Storage' from bootloader and I finally booted up OK. What does Clear Storage do exactly? haha
the stock recovery apparetnly has the ability to wipe parts of the phone that a custom recovery cannot. the stock recovery is also able to somehow install firmware,wich custom recoveries do not,so it stands to reason the stock recovery has a few tricks up its sleeve i believed it worked in your case becasue it cleared out the residual perosnal data from newts rom.
EDIT4: Well that got the phone to boot, but I don't have any of my apps data. Like, it grabbed my wallpaper but I don't have what I need to restore a titanium backup. So I still need help.
hopefully you made a backup of newts before starting to update?
this is prolly not exactly what youll want to see,but the best thing,IMO:
1)wipe and restore working newts backup. before rebooting,wipe cache and dalvik,and reflash the same version of newts rom,so that it will work with new firmware.
2)once youre in your working backup,use titanium to backup apps and app data only.
3)make a backup of working newts rom,in case you want to come back to it,you wont have to reflash the rom over your old backup to get it working on new fimrware.
5)restore aps with titanium. wallpapers,ringtones,etc. should remain unmollested on the sd card.
and for anyone else watching,make sure youre fastboot boot
ing recovery each time(i know you know that
