[Q] Nandroid backup and boot image restore

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.

Question about ROM backups

When you make a backup of a ROM using CWM does it also back up and reflash the boot.img when you restore from your backup? Or does this mean that you still have to reflash your kernel after restoring the ROM? Or what's so useful about a recovery?

No it doesn't restore it for you ,you have to reflash stock Rom

yes, u have to flash the boot.img or the restored rom wont boot. for example, i was using AOKP with TITANIUM KISS USB then i restored my previous PA backup. it was not booting it stuck on bootanimation.then i flashed hellboy kernel then it booted.....

Yes

Since we have a s on device we have to reflash the kernel

[Q] Doubts about recovery!

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.

[Q] Quick Question on boot.img from Nandroid recovery...

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).

[Q]Returning back to stock

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.
