{HOWTO-beta} Backup and Restore in ICS - Revert to Gingerbread from ICS

So there has been a lot of discussion in other threads about backing up,
and restoring ICS ROMS. I had to find out what is possible and what not.
I wrote down the steps for reference,please if you find that there are corrections or additions, post!
Here's the deal:
It can be done, you just have to flash the Abysnote 4.0+ kernel everytime you want to do a backup or restore. This is also the way to safely revert to a Gingerbread Nandroid backup, after you're done playing with ICS.
There's a few caveats, if you do a backup of ICS and you forget to reflash
the ICS kernel, you will be trying to boot ICS with an Abyss kernel...
Something I never did, but it might end you up in the, well... abyss.
Also, I found myself first scared, then confused with the occurence of
an LP5 repack from Chainfire, that is admitted to be a high risk release.
Then you see LP5 ROM's popping up, so you think, might they be using
that LP5 repack and am I inherently in danger? Seems not the case.
One can flash the ROM's by the Chef's containing LP5 kernels, but from what I learned, the base is OK anyway. *please correct me here if I'm wrong.
Here's the scenario's, tested once by me on accounts 1 and 3. 2 is beta but hearsay says it works. Anyway, it most probably won't hardbrick your device if it doesn't You'd still have recovery mode from holding down home-volume up-power until white samsung logo appears.
1- Howto create Nandroid backup from a working ICS rom that you have.
So, if on ICS, and want to make an ICS nandroid (i.e.progressive installation/configuration backups), you can :
- reboot to recovery mode
- flash abyss 4.0+ kernel
- reboot to recovery after the kernel flash is done, dont boot the Android phone
- you are now in a different looking recovery mode, don't panic, its almost the same
- do your nandroid thing
- after the nandroid has finished, reflash the kernel you had in your ICS ROM
- after that, you can reboot to recovery again, or select reboot system.
(I always reboot system after I reboot once more to recovery)
2- Howto restore ICS Nandroid backup from a working ICS rom that you have.
So, if on ICS, and want to restore an ICS nandroid (i.e.progressive installation/configuration backups), you can :
- reboot to recovery mode
- flash abyss 4.0+ kernel
- reboot to recovery after the kernel flash is done, dont boot the Android phone
- you are now in a different looking recovery mode, don't panic, its almost the same
- go to restore menu, select the ICS nandroid that you want to restore
- **not tested by me, but there should be no need to reflash the ICS kernel as it has been overwritten by the restore**
- after the nandroid restore has finished, you can reboot to recovery to reboot system
(I always reboot system after I reboot once more to recovery)
3- Howto revert to Gingerbread Nandroid backup from a working ICS rom that you have. (Safely going back to GingerBread without much trouble)
reboot to recovery mode
- flash abyss 4.0+ kernel
- reboot to recovery after the kernel flash is done, dont boot the Android phone
- you are now in a different looking recovery mode, don't panic, its almost the same
- do a fullwipe/factory reset
- restore your GB nandroid using backup/restore menus in CWM
- after the nandroid restore has finished, do a factory reset/full wipe again
- after that, you can reboot to recovery again, or select reboot system.
(I always reboot system after I reboot once more to recovery)

Hi ... I got a hint from stunner thread that backups work on lp5 kernel ... I've done one without any apparent issues but don't know whether it would properly restore if required? ... If yes, it would avoid the need for this multiple flashing of kernels .... You can also try and confirm ...cheers.envy

+1 I'd like to know this as well. I made a direct nandroid in stunner recovery without flashing abyss.. Hope it won't be a problem.

Well.. if you guys already made the backup with the LP5 kernel,
could you take the ""risk" and try a restore ? You would the first the really
confirm it, and the thread would grow in information worth.
I guess the worst that can happen is that you have to use ODIN to restore a stock
ROM and then restore your ICS backup using Abyss.
More likely is that you can just flash abyss if it doesn't work, then flashback ICS backup. Hope you will try. Im back on GB.

Sorry for hacking in
I too wrote the instructions how to shift to GB rom from ICS rom !!

Thanks for you detailed instructions on various scenarios!! Good one!
Cheers! Enjoy your Note!!

Sorry but I'm a bit confused. I'm on Stunner, and would like to do a nandroid backup, and continue using stunner as is.
Steps:
1. Get into recovery and flash latest abyss, then reboot to redpill recovery, then perform nandroid.
2. How do I revert stunner as I had it before, since kernel has changed? The only file I have is the stunner rom package itself. No separate kernel to flash. Should I just restore the newly made nandroid to get back to the way I had it pre-abyss? Wouldn't the nandroid backup have stunner rom+abyss kernel, which I don't want?
Thanks!

Tested by me - the ICS kernel has not been overwritten by the restore

First of all thanks to "lucid" for the thread!
I am on ICS Stunner 1.4.19. I followed the instructions above and did backup and restore as described.
I have tested to restore the nandroid backup and reboot without reflashing the kernel. Well, that didn't work. My Note stuck on Samsung logo. Fortunately I was prepared for it beforehand. I had previously extracted the kernel from my Stunner. So I rebooted into recovery again and flashed the ICS kernel (3.0.15-I9220ZCLP5-CL295568).
Peace!

[q] stuck plzz help abysskernel !!!!

HI, guys i had perfectly fine working note but some how wanted to flash abysskernel to overclock downloaded and flashed it on ICS stock rom....and crap now m stuck at boot of my galaxy note .....stuck at boot animation of custom logo not going further. i downloaded costom logo abysskernel and flashed it through cw mod.
plz hellp all tech giants and masters here as i dont want to format my phone a lot of stuff is thr...please tell me how to go back to previous state without losing data. i have tried wiping cache and dalvic cache but still stuck at boot....HELP!!!

abyss kernel cannot use with ics since it is a gingerbread kernel. a ics is required to have a ics kernel for it to work. what can you do is if you have a nandroid backup, just restore it using the abyss or if you are running a stock ics, just find a compatible ver of cfroot ics kernel and flash it via abyss.

First of all, if anything goes wrong, this is your safest way to not cause any additional harm to your device: http://forum.xda-developers.com/showpost.php?p=18981227&postcount=4
But since your backup is not working, you don't want to employ this method right now.
So you just follow the advice of janice1234 and find a compatible (with your ICS version) cf-root kernel (v5.6!) here http://forum.xda-developers.com/showpost.php?p=26746339&postcount=7, copy it to your external sd via anything that lets you access it (e.g. adapter or another phone) and flash the kernel with abyss.
While you're in the dev section you could do some more reading, for example all the information chainfire provides in his cf-root kernel thread...

hi got all u told me just one more thing how to flash wia abyss.....dont know how to ...i know how to flash via cw recovery touch i have it but from theer cf root have .tar file and it cannot be flashed through cw recovery so how to flash cf root from recovery. thas all i need to know.
thanx

You need to download a rom that can be flashed through cwm / abyss red. Try criskelo v7 ics. Download to your pc, copy it to your SD card using SD card reader) then reboot into recovery and flash it. If you have stock ics, I would do the 3 wipes first before flashing the new rom. Make sure you are doing all of this from abyss 4.2 cwm and not ics cwm.

Usually people run into this problem the other way around.
Anyway, once you have downloaded the .zip file there is no need to unzip it, since the .zip is exactly what you need to flash in CWM as it can't handle the bare .tar.

CWM - full wipe / nandroid problem

2 days ago I had to reinstal system on my Note. I decided to flash stock GB rom using odin with re-partition (SGN 16bg pit file). After that I flashed once again using stock GB rooted rom, and install CF kernel with CWM using mobile odin. Everything was fine. Next I installed a cooked rom (CleaNote v5, ). I thought that everything is fine till i decided to install TouchwixUX Launcher prepared to Note. The instalation process stucks on about 20%, I thought that maybe package is corrupted, I downloaded it again, but it didn't help, so I decided backup my phone using nandroid and wipe to factory data. And there is a problem:
1. I try to make a backup using nandroid, and it stops on some *.txt file and stucks. (backup include 3 files)
2. I can't do the wipe. I launched full wipe and nandroid returned a message "can't open /SDCARD/.amndroid_secure ..."
3. When I try to mount SDCARD, CWM Recovery show's the message "Cant mount SDCARD"
There is a one thing which make me sad. I tried to install CleaNote .zip by CWM Recovery once again, and instaltion process stucks to. It means that i probably wont be able to flash any other rom.
Is there any way to solve this problem?

Can you go download mode and flash gb rom in pc odin? After flashing gb rom in pc odin if still stuck go to recovery and wipe data and cache.
The way you explained it i dont believe it is superbrick.

NO NO NO - there is no superbrick My phone works, I can connect phonr to Odin, Mobile Obin, I can run in Recovery mode, but i can't for example do a nandroid backup or ful wipe under cwm recovery. I think, that there is some problem with permition to files on SD card, but I didn't meet with that problem on other rom (I used Paranoid Android (CM9 and CM10) and there was everything fine).
The reason I wrote is that I am worry if some parts of internal memory maybe corrupted, and flashing rom using Odin/Mobile Odin may caused superbrick.

Download EMMC CHECK from google play and after you run it check your heart also.

I used eMMC Brickbug Check. Result - Congratulation, test pass.
So I understand, that if there is some bug, there is caused by software, not hardware problem and I can reflash phone using Odin.
BTW - what means "Brick Bug ? - Yes. Insane chip." ?
I change kernel from stock to CF 5.3 before flashing to CleaNote. I found some info, that this kernel (cf 5.3) is not safe. Kernel after flashing ia NoteCore 12,3. Can it be the reason why i couldn't do a full wipe?
... I almost forgot - I used TriangleAway to remove flash counter. Maybe this is a problem?

[Q] CWM Restore after flashing custom ROM

Hi there,
I have a rooted N7000 running original Android v 2.3.6
I want to flash (test) it with a custom ROM.
I made a full backup of my current system (via CWM backup)
Now, when I flash a (new Android 4) custom ROM, will it then be possible to restore the old v2.3.6 image that I made, using CWM?
Other question: Do I need to take care of what type Kernal version I have
I have 2.6.35.7-N7000XXKKA-CL726566
Baseband-version is N7000XXkk5
Thanks for your reply.

nothing to worry about, that is what backup is intended to do.
the only thing you have to watch that you're on safe kernel like philZ when wiping data in stock ics or jb (read sticky threads)
example: if you are on philz kernel and runing ics or jb, when you restore your backup of gb, you restore your gb kernel, system, data etc, just like backing home

OK, Thanks for the reply. So if I understand correctly:
1. I make a backup of my current ROM (Image via CWM) and put it in a safe place.
2. I can flash any custom ROM, and test/play with them.
3. Afterwards I can put back my old ROM again via CWM restore.
4. Reboot, and I'm back in the old state.
Is this right?
Can I flash ROMs by using CWM also (using zip files) or do I need to flash, using Odin?
I actually do not understand your remark about philZ, can you explain a bit more about what that means.
Thanks for your help so far

Since you are going to try custom rom, you need not to worry about emmc brickbug, since they will be using a safe kernel..but double check before flashing...so, if you are on Stock ICS kernel, you should NOT wipe/factory reset..if you do, you will brick your phone..you can just go through couple of sticky threads to know abt emmc brickbug, if you are not aware of that..whatever the steps you have mentioned above are correct..but when you flash a custom rom, follow the instructions mentioned in the Custom rom OP...

1. Yes, copy your /clockworkmod to your pc (just for double safety) dont cut it or move it, you need it on your internal sd card always, if you wanted to restore it again... and dont rename it (you will end up with message md5 missmatch!)
2. of course
3. Every new custom kernel like Philz kernel ( for ICS TW and JB TW) http://forum.xda-developers.com/showthread.php?t=1901191
or hydracore (not working on TW JB, but works on all other) http://forum.xda-developers.com/showthread.php?t=1749863
have built in CWM 6.x.x.x , You can recognize them by the gray background in CWM recovery. (there is no need to install independet CWM or something else, like you do on your stock GB kernel)
They are built in almost every custom rom, and these kernel are safe for wipe.
3.1 . So if you flashed new custom TW ics or jb, and after playing with them, you want back to your nandroid backup, just go boot in recovery (now you see a grey background CWM6) do all the wipes (in my experience the best way is: (advanced > wipe dalvik cache, go back > wipe cache, then wipe/data factory reset, then go into mounts and storage > format cache,system,data and preload , dont format emmc and sd card. go back into backup/restore > restore from (internal sd card or some other place depends on where you place your backup)
4. of course, when youo see a message backup complete, reboot it

[Q] CWM Recovery is not booting

Hi
I have here a Galaxy Mini running stock Froyo 2.2.1 without an USB-cable.
My goal is to flash CM 9.
I rooted the phone with an update.zip containing Superuser.apk and the su binary. (I needed it for Titanium Backup)
I want to install CWM too but I can not use Odin (no USB cable). I downloaded CWM Touch 5.2.0.8 from this thread: http://forum.xda-developers.com/showthread.php?t=1439751, named the file update.zip and flashed it with the stock recovery tool. - This seemed to be sucessful.
But now the devie is stuck at the "Samsung" logo everytime I try to boot into recovery. Booting the normal Android works fine.
Is there a way to flash CWM without using Odin now? (probably using linux "dd")
I would like to have CWM before I flash CM9 beacuse I want to create a full backup first.
Edit: Ok...I might have overlooked that this CWM is for Gingerbread.
Thanks

flashing through stock recovery may not work
you have to use odin to flash the recovery
one more thing is that you cannot backup stock rom
you must upgrade to gb to flash cm9 (bootloader incompatibility)

A full back up of what ?
If you try to back up your current ROM app data, then restore it on cm, there'll be bugs potential.
