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]Quick Question about Kernels and Roms

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:

[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.

is it possbile to restore backup rom with CWM?

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.

Uninstalling Custom Kernel?

I was wondering if I just flashed this new kernel on my phone but don't like the way it functions, how can I uninstall/unflash it?
Thanks

Create a backup using TWRP, then if you don't like the kernel you can just restore your backup.
