I was running a ROM versed on ulcb3 and using the entropy DD kernel. I just restored a nandroid backup to an L2 based ROM that was packaged with infusion-GB A2. I wiped prior to restore in cwm.
My settings now tells me I'm using the b3 baseband, and I can't tell what kernel I'm on. does a nandroid backup restore the modern and the kernel? I'm guessing kernel yes, modem no. Can anyone confirm?

You have to flash the kernel you were using with the backup. I wipe data, flash the kernel that is supposed to be with my restore then ill do my nandroid restore. You then have to flash the modem that you want. Doing restores on the infuse is a little tricky at first.

On a similar note.... when switching between roms that are both nandroided, full wipe, cache, and dalvic are still necessary? I figured a nandroid restore would rebuild the whole phone to the snapshot that was taken at the time of backup......

I do a full wipe. It only takes 20 seconds extra.

Ya for some odd reason when i attempt to use the nandroid back up & restore future i get bootloops on the samsung screen upon restoring, i don't get it. On my HTC i can do it without any problems. Do i have to flash the appropriate kernel for the ROM when i want to revert to it?

When restoring a nandroid, you should only restore the data in the advanced restore option. Make sure to do wipes prior to flashing a new ROM.

did a search didnt find anything...
I hear ppl backup and restore there using cwm what does that do ? why does it actually restore?
When you back up using CWM you are doing what is called a nanadroid back up. When you run the back up it creates a complete image of your phone in its current state so all system and data apps, personal settings widgets on your home screen etc are all backed up. So if you flash a new rom and you don't like it rather than starting from scratch you can just restore your nandroid and your phone will be back to the state it was before you flashed the new rom
I would recomend doing a nadroid back up before you flash anything in recovery, some people might say this is required but in my personal experince it can't hurt.

thanks i guess ill just back up after i get alll my settings like ringtones, settings, apps downloaded etc.
why would i do it b4 i flash anything in cwm?

If you flash something in cwm that you were not supposed to, like a theme not designed for your rom, it can cause the phone not boot. If you did a nandroid you can just restore and everything will be back to how it was before you flashed

it is a really simple thing.. I just did it for the first time and it feels easy and nice to have your whole system backed up on your sd card
Hey.
If I flash custom rom and then decide to go back to stock rom, do I just run the nandroid backup on top of the custom rom, or I have to wipe or something to make it run smooth and fast?
Thanks.
I just restore. But if u feel a lil frantic about issues do the normal wipe process

SAme here, never wiped, always worked great.
It wont hurt, but it wont change anything either, because restoring the nandroid rom actually does that for you automatically
Just want to make sure if the nandroid backup & restore is really working on Sensation with latest CWM since I have made a bunch of backups and I am heavily messing around with the phone for the past 48 hours lol... Just to be sure this backups are going to actually work in case I screw the phone...

Do remember that clockwork /nandroid restore will not restore the kernel. If you flashed a rom that's using a custom kernel, you will need to flash the stock kernel before trying to restore your backup or you will get stuck in a boot-loop.
Thank you both! Just wanted to confirm!

Yes, I'd love to know this along with how to get a copy of the original kernel....or is the kernel in the .zip files on the regional oem rom thread?
not working for me
You can find the stock kernel in the second post in the Android Revolution HD thread over in the development section.

isnt the boot.img the kernel and init stuff? i was under the assumption it was backed up when you do a nandroid on most devices (like HTC). the RFS file system samsung uses on their devices prevented us from backing up and restoring a boot.img file so we have to always have a kernel in case of the good ol boot loop
so to go back to stock kernel, i install it to the sd card then flash it in recovery right?

Yeap... That's how you flash a kernel, but not needed if what you want to do is restore from a nandroid backup... To restore just select the nandroid backup you want to restore. No need to flash any kernel prior restoring from nandroid.

since when do you have to reflash a stock kernel in order to flash your backup? I have tried every rom out here for the sensation didn't like any of them and reflashed my backup of stock with no issues....

This is not true. Nandroid contains the kernel image.
You would only have to flash a different kernel AFTER you restore, if you don't want to use the one that you backed up.
To the point, nandroid restore works perfect with 4.0.1.5 CWM. I confirm.
Getting mixed signals here guys. Does nandroid backup / restore the kernel?

I decided to try out the cornerstone aosp so I made a nandroid backup, did the usual stuff and tried it out. Once I was done messing around, I wanted to restore my nandroid but after I do it doesn't boot. Nothing I try works so I end up wiping everything and installing fresh. Second time its happened where restoring wouldn't work. Anyone else have this issue? Also could u take that backup and put it as a zip file, place it on ur SD card and flash it through recovery? Would probably get the same result though

its not an issue nandroid does not restore your kernel. You need to restore your nanadroid then reflash the rom that you were using when you took the nandroid

So I need to just restore then flash the rom that the restore was based off of? Thats easy enough. But I thought there was only one kernal across ics for the tf101 atm

Here are some tips on what not to do when restoring a nandroid
A. Forgetting to wipe system before restoring a nandroid
B. Forgetting to wipe data, cache, and dalvik at the same time

Yeah wrong section.
My advice: know which kernel you are on before doing a nandroid backup. Make sure you are on a compatible kernel first, flash the same rom as the nandroid backup just in case.
You know better
Forgetting to run Qkster wipe script.
Sometime renaming the nandroid zip creates trouble.
Actually I was referring to when you wipe everything on ics cwm recovery and trying to restore a nandroid
Sent from my SGH-I997 using xda premium
I've restored nandroids many times and have NEVER wiped anything before doing so without any issues. I'm not sure why you'd worry about wiping everything when it is all overwritten by the restore process.
it happens between the Slim ICS Restore and CM9 flash
