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...

Yes.... Works great.

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!

Question. What was the total file size of the Backup (stock ROM)?

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?

Nandroid is just the CWM backup? Or am I missing something?

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?
(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.)
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
I always see in every ROM thread to do a Nandroid back up before flashing a new rom but I don't know how to do it. I had been always flashing roms without doing any kind of back ups, except text messages. now that im curious about it and for future issues. how do I do it, the nandroid backup?

In ROM manager tap "back up current ROM " or in recovery choose "backup and restore"
The back up (nandroid) will back up everything but the radio... It'll make an exact copy of your ROM.
Then when you need to... In rom manager, tap backup and restore... Then choose your latest backup.. Or whichever backup you wish to restore.
Basically same process from recovery screen.

I would recommend performing the backup/restore while in clockwork mod recovery. Its less problematic than doing it in rom manager.

Is it possible to backup roms and restore them with clockwork recovery? I just rooted and installed cw probably a weekago. I downloaded and flashed "energy rom" I didn't like it because imo it had slightly less battery life so i tried to restore my backup of the stock rom but instead of it working right after it got stuck at the htc logo boot screen. I had to download stock which found out I needed a computer to even get stock back. So my question about can I backup and restore at least stock rom without needing to use that ruu file?
Sent from my HTC Sensation 4G using xda premium
you can always restore your backups via recovery, as long as your backed up before you flashed whatever you do not want anymore. be sure to back up before you flash anything your not sure of.
Ok thanks for the reply. I know you can restore backups i've done it on my myTouch 4G and g2x. Problem was that I didn't like the rom I flashed tried to go back to stock from my backup and i got stuck at the htc bootscreen.
Sent from my HTC Sensation 4G using xda premium
And since to get stock back I needed to download the ruu file on my computer so i wasn't sure if that was the only way.

You can always wipe and reflash whatever rom you choose without any back ups also.

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

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?
Sent from my SAMSUNG-SGH-I997 using XDA App
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......

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.
