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,
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.

Hi
I backed up my stock rom with the correct boot.img.
I then flashed the boot.img supplied with the insertcoin rom and then flashed the rom itself.
When I wanted to restore the backup of the stock rom I also had to flash the boot.img again - is this normal? I was expecting that when I did a restore of the stock rom it would also have backed up the correct boot.img?
Let me know if I'm doing something wrong
Thanks

Because the phone is currently s-on you can't flash boot.IMG from.clockworkmod has to always be done from fast boot.

Hi there
I just installed venom on my one x successfully and now I'm looking at kernels
Mainly the Bricked kernel
I'd just like to ask if I flash this kernel, and want to restore my phone with my original sense backup (the first nandroid backup I took), do I have to flash another kernel before I can restore the back up or does the Kernel only affect the rom currently installed?
I'm extremely sorry for the unclear language, I'm not exactly sure how to put it
Thanks,
Yadash
When you restore the backup , you have to flash the boot.img (kernel) from that particular backup. It's located in the backup folder

Thanks man!
So basically if I install another rom now, and want to restore the backup I made of Viper
I find the boot.img of Viper and flash it and then restore the rom?
Also when I factory wipe to install the next rom does it clear the kernel too?
Let's make it simple, if you flash a rom you also always flash the kernel from that rom !
The same for a backup.
If you flash some other kernel to a different rom , it won't boot !
If you completely wipe your phone the kernel will stay. The kernel will only be overwritten by flashing a different kernel.
Thanks again
I completely understand now, and thank you so much for the help!
No problem. :thumbup:
Sorry one last one
If I install the bricked kernal and want to go back to the original one that viper came with
Do I just run the boot.img that came with Viper?
No, let's say you flash the bricked kernel
Flash the boot.img with fastboot commands and then enter the recovery and flash the modules from the bricked kernel.
If you want to go back and flash the boot.img that came with viper x you will get a bootloop because the modules do not match.
Or you flash the boot.img from viper and reflash the rom without a full wipe
Or you can use the venom flasher to install different kernels of your choice. The custom (stock viper) is also included in that tool
Oh awsome sir, thanks so much again!!
I'm still a Huge Noob at this sort of stuff
No problem :thumbup:
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 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).
