I am currently using cm10 with hellboy kernel and have a cvm backup of stock rom. I was wondering if *touchwood* something were to happen to the custom rom will a simple recovery be enough to get back to sense? or is there some kernel which will have to be flashed first? or is ruu the only way of going back to sense?
if u have a nandroid backup of stock ROM u can restore it and flash the boot.img found inside that particular backup.if u do not have a stock backup u will have to apply ruu or u can even restore nandroid backups of stock ROM found on XDA.

Hey,
If you do a nandroid backup, then wipe, flash a new rom and a new boot.img, will the boot.img from the previous rom be restored if you do restore it? Or do you have to fastboot flash it again? If so, is the boot.img which is found in the backup folder the one to use?
Thanks
yeah i am wondering the same question. Actually I have a nandroid backup of the stock rom, and i flashed other roms before too. I tried nandroid restore and everything did go back to stock, but I am concerned whether I need to flash any boot.img? if the stock kernel is untouched while flashing other roms, does that mean i dont need to reflash the boot.img?
When flashing other roms the stock kernel is not changed. Unless you have an s-off device. If you did not fastboot flash boot boot.img then when you restore your back up you will be fine. If you did flash a new kernel then you will need to flash the boot.img for your backup as the backup will only restore the kernel on s-off devices.

Hello,
This is probably a silly question but I was just wondering if I had to reflash the correct kernel when I restore a ROM. Let me give a scenario as I don't think I can find a decent way to word it.
Lets say I flashed PACman last week and that runs on Hellboy CM10 kernel but then I fancied a change so I did a Nandroid backup in CWM, flashed a Sense kernel (Like Titanium Kiss) then flashed a Sense ROM such as SuPrimo. If I decided to switch back to PACman would I have to flash the boot.img (Hellboy CM10 in this case) before hand or is the boot.img stored in the Nandroid backup?
I'm just curious.
Thank you,
Curtis.
Hello Curtis,
The boot.img is backed up in the nandroid backup.if you open the backup using winrar,you will be able to see it.
you will need to flash the Hellboy kernel again or Pacman will not boot.
If our device was s-off,there would be no need to flash the kernel as it would automatically flash it.
It(boot.img) is stored in the backup,but you must flash it.
U must flash boot.IMG while restoring pacman... that's what while restoring ROM first u should flash boot.IMG

Hey guys, just a quick question about restoring from a nandroid backup. Let's assuming I'm using custom rom A and made a nandroid backup of it. Then later on, I change to custom rom B and made another nandroid backup of that.
Well, assuming the boot.img from both custom rom A and B are different, then say if I were to restore back to custom rom A, I would have to re-flash the boot.img for that rom correct? OR, will restoring custom rom A from the nandroid backup also flash the boot.img for me automatically?
I came from other phones where flashing a new rom or from a nandroid backup is simply a one-step process. HTC One X is the first phone I've used where I have to deal with flashing the boot.img as an additional step as well, so just wanna confirm if this is the case for a nandroid restore as well.

You have to flash the boot.img for the ROM you're restoring through fastboot. Recovery cannot flash boot.img for you since you need S-OFF, which impossible to achieve (let's not go there).

yup got it. Thanks!
Before flashing rom, i always make nandroid backup of my current rom.
But my question is right now i am on stock rom(with KTT kernal) and i am looking to flash cm11.
If i flash cm11 then can i restore my backup rom with CWM?
will i get all my data data on my stock rom?
or i have to do all the same thing flash stock rom with flash tool and again root it and install cwm all this things.
It would be great if you help.

Hello!
I need to return using a stock rom (at the moment i'm using aicp). I have a nandroid backup of the stock rom just after unlocking the bootloader, but since then i changed kernel (from stock to xmister) and the recovery (from clockwork to twrp). Do i have to change recovery and kernel before restoring the nandroid backup? or can i leave everything as it is and flash without problem?
Thank you!
Flash the stock boot image from the nandroid zip and also a jellybean cwm recovery as the kitkat recovery will not let you restore jb nandroid.
