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
Manny

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

I've been playing around and checking out a few ROMS (CM9 and CM10), but since they aren't fully complete I want to go back to stock. when I rooted I made a Nandroid backup in recovery. Now If i want to go stock again do I just wipe everything and use the backup I made. Still confused because I flashed kiss kernal. Will restoring remove the kiss kernal?
No need to wipe before you restore your backup, and it will install the stock kernel also

No... restoring from nandroid will not removed the flashed kiss kernel.
You need to flash a stock boot.img first before nandroid restore or you can flash kiss kernel that is meant for a sense rom first. Without reflashing kernel, you'll be in bootloop.
My bad

I asked this in the IRC and was told you would need to flash the stock ROM (RUU?).
Think its this thread:
http://forum.xda-developers.com/showthread.php?t=1591059
Someone could verify.
Not sure how to tell which one you need either. Anyone know what I'd need for Koodo Canada version?

I would get the Telus RUU, but only flash the kernel (boot.img) as I imagine that even if their ROMs are different, they'll be running the same kernel.
Here's how to get the boot.img out of the RUU:
Run the RUU (no need to connect the phone, all you want it to do is extract)
Go to %temp% (Start, Run..., enter %temp%)
Sort by date to find the most recent folder
Find rom.zip in there, open it and extract the boot.img wherever you like
After that you should be able to just fastboot flash boot boot.img like any other kernel, and restore your original nandroid.

Thank you, I've bookmarked this thread for my future use
Loving the speed of CM9 since I'm assuming its mostly due to the OC'd processor.

you need to restore a kernel that is compatible with stock roms, or either the stock kernel itself. Please note, that the boot.img inside the nandroid is NOT a fastboot flashable one, and cwm will NOT flash the boot file.
Also, it is unsure, that one phones nandroid will work in an other phone, not to mention that if cid mismatches it won't even work (this is a lesson I have learned in my own faliures).

I can confirm the nandroid from other phone is working for another phone. I just tested that. Use the nandroid backup for my phone and restore it on my wife's phone. Tested with a 2.09.707.1 nandroid backup. Once reboot, the OTA update notification is there.
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).
