{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] Returning to stock GB from ICS Stunner - stuck at CWMR

I had ICS Stunner in my Note working properly.
I needed to revert back to stock GB, so I downloaded the stock ROM from here:

Download AbyssNote 4.2 kernel with redpill touch recovery from here- http://forum.xda-developers.com/show....php?t=1362424 .
Now first put this zip on your SD Card before you try to flash anything or restore anything.
Now boot into recovery - Volume up + Home + Power
Choose - install zip from SD Card
Navigate to your Abyss kernel 4.2 zip and flash it
After flashing is complete- go back to the Recovery start menu
Go to advanced > reboot recovery
This will reboot the phone directly to new recovery - Hyperdroid Redpill Recovery
Now go to Wipe Menu and wipe cache, dalvik and do your factory reset
After this start your restore from nandroid backup , or flash any GB rom !

I've done everything up to "After this start your restore from nandroid backup , or flash any GB rom".
When I try to "choose zip from internal card" and choose the beforementioned ROM, I get the message "E:Can't open /emmc/1/GT-N7000..... Installation aborted".
If i try to choose file from external SD card I get "Can't mount /sdcard/".
I've tried flashing Abyssnote 3.9 as per this thread http://forum.xda-developers.com/showthread.php?t=1599229
Still same problem.
Does it have something to do, that the ROM I've downloaded isn't the same as my original ROM? (I mean the letters at the end, like LA4, KL2 and so on. I can't remember my original ones)?
And I don't have any backup.
Can someone help me get back to ANY gingerbread?
Thanks a lot in advance.

I think you should go back to any stock rootable GB ROM using ODIN. Then flash your custom GB ROM over it and then restore your apps using Titanium Backup or any such tool provided you have used the same to back up your apps.

Go to this thread
http://forum.xda-developers.com/showthread.php?t=1535025
And download any one of the pre rooted GB ROMs and flash it using Odin
The difference in ROM title does not affect flashing

Had the very same problem. At a welknown site a registred and downloaded a original rom. A rooted rom did not worked with my Note. After that i flashed the Rom with pit file completely. And yes, miricaly it worked! My only problem was that i picked a rom which had no rooting available so i had to downgrade. I downgraded with a rooted rom and finaly i was where i left some 5 hours before, but now with a working device!!

I don't know if I can post after this time, (couldn't get my hands on that phone and check out your advice), but now I've tried it and it works perfectly - thanks!

Restore from Nandroid

Hello all,
I recently upgrade (for my first time) to ICS ROM with ABYSS Kernel,
but of course before my upgrade i backup my phone - Nandroid backup.
My question is:
can i restore my Nandroid image and all my Data, ROM and Kernel will be restore??
Thanks in advance,
Bar

Do NOT restore a nandroid backup with CWM on any of the stock ICS roms. You will need to flash the Abyss kernel to restore a nandroid.
What is the nandroid backup of? Like which rom?

The Nandroid backup i have is from my GB stock ROM,
can i go and restore form it?

Yes but first you must flash abyss kernel. Reboot into abysskernels cwm then you can restore the backup.

I already have Abyss kernel installed, is there another Abyss version for gingerbread?
my current Abyss version is: AbyssNotekernel42CWTouchOriginalLogo.zip

That's the right version. However, Abyss is just for Gingerbread and restoring nandroids. So, you couldn't have been booting ICS with Abyss because it wouldn't boot up, at least not correctly.
But yeah, if you don't have it flashed, flash Abyss, reboot recovery, and restore nandroid.

Thanks andreww88,
Before my upgrade to ICS i went through the below link instruction:
1. install Abyss Kernel
2. reboot into it
3. wipe data
4. install rom
Link:
http://rootgalaxynote.com/galaxy-note-roms/kingdroid-ics-rom-v2-0-for-galaxy-note-gt-n7000-best-ics-romtouchwiz-ux/
please give last green light that i can go and restore Nandroid if i have Abyss ver 4.2 already installed on my GNote N7000?

Have you installed abyss again after ics?

Hi Belfia,
This is my problem, i failed install kernel.
after i installed Abyss and KingDroid ROM all went well, till i reboot into recovery via Rom Manager...
what can i do to go back to gingerbread? (i am afraid from bricking my device...)

Now, I understand you. Any time you flash a rom it will install the kernel that goes with it. So you flashed stock ICS so you have the stock ICS kernel (so do NOT wipe data and do not restore nandroid). Reboot into recovery. You need to flash the abyss kernel again in CWM. Then, you need to "Reboot Recovery". It should be in Abyss now. Now, you can do restore nandroid.

i think i was not clear enough, i will explain again:
After i installed Abyss and KingDroid ROM all went well, till i reboot into recovery via Rom Manager...
Now when i try to install Abyss Kernel again it's failed, it is stuck on "Installing Update..." (see screenshot attached).
what can i do to go back to gingerbread without bricking my device?
Thanks you all

OK - don't reboot after you install Abyss Kernel
After you install zip - choose Advanced > Reboot into recovery.
Don't reboot after install Abyss - it is likely a bootloader problem. Check out the video on first page and you will see that what I mean.

[Q] safely wipe clean note with ics?

I have N7000 with ICS (4.0.3) and XXLQ2 firmware. I have flashed chainfire's CF-Root kernel. BUT I want to completely reset/wipe the phone to its pristine condition. I have checked 'got brickbug' and i have got the brick bug. so what am i supposed to do? If I wait, will this bug be resolved by Samsung in an upgrade to ICS, or should I go 'back' to GB (if so, how), or can I ignore the brick bug thing and get on with it?

So you don’t want the Odin back to GB. Well then you have the Abyss Note 4.2 Kernel with Redpill Touch recovery. You are on any unsafe kernel ICS Rom and you want to go to safe rom then do one last CWM flash of Abyss kernel reboot recovery and then flash the safe roms. This keeps your root intact. You can even acieve root though this if you have lost it. Just flash Abyss 4.2 go to GB. Check root there and then flash the ICS rom. No need of repack. If any of this gets struck or brick then you know your way out already…..you told that in the question. Link for Abyss 4.2 Kernel is here.http://forum.xda-developers.com/showthread.php?t=1362424 --Download AbyssNote 4.2 kernel with redpill touch recovery Or Abyss 3.9 Kernel (for some users where the 4.2 kernel haven't worked 3.9 worked perfect).
--Now first put this zip on your SD Card before you try to flash anything or restore anything.
--Now boot into recovery - Volume up + Home + Power
--Choose - install zip from SD Card
--Navigate to your Abyss kernel 4.2 or 3.9 zip and flash it
--After flashing is complete- go back to the Recovery start menu
--Go to advanced > reboot recovery
--This will reboot the phone directly to new recovery - Hyperdroid Redpill Recovery
--Now go to Wipe Menu and wipe cache, dalvik and do your factory reset
--After this start your restore from nandroid backup , or flash any GB rom !
Cheers!! Enjoy your Note!

Can be used to wipe only

[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
