{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

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.

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!

Which ICS rom for GT I9000?

I want to flash my galaxy s to some ICS rom but I don't know which one to use. I don't want to mess with my phone with trial and error so please do suggest which rom is better. Plus, I came from gingerbread rom which is darkyrom 10.4.2. Do I need to do something first before swtching to an ICS rom like flashing base through odin and do a CWM? Quick response will be appreciated. Thanks!
Sent from my GT-I9000 using Tapatalk

Just make sure you backup your contacts and anything else you need, for me contacts are the most important (synced to google)
If you have a stock GB or Sammy rom I guess it wouldn't hurt to flash that through odin first, just make sure NOT to tick repartition.
If not, just disable any lagfixes (I just got a Galaxy S and have never used any so I have no idea how to disable them) and go into CWM, wipe date, cache, and dalvik cache (in advanced menu)
For which ROM to use, Slim ICS is probably the most popular right now:
http://forum.xda-developers.com/showthread.php?t=1488096
I have used this personally and I find it very fast, I just don't like that there are no music controls in the status bar when you pull down the notification thing, which is very important to me. I also hate the launcher that comes with it (Zeam) but that's just me and ofcourse you can easily get another one such as Nova or Apex.
I am currently using Infinitum 2.1
http://forum.xda-developers.com/showthread.php?t=1572705
Very stable, very fast, lots of customization. I highly recommend this.
I have also used Dark Knight and CM9 Nightlies, although they are great ROMS, they just don't compare to Slim and Infinitum (This is just my opinion). I found Dark Knight very slow and laggy, but it was my first time flashing an ICS rom (previously used CM7 and MIUI 2.3) so I may have missed a step or two. CM9 is epic but is missing the customization features that Infinitum has.

Why is it a big deal not to tick repartition? And I read some post regarding wiping imei when you switch to ICS. Is it true? Can you give me a link for the stock rom?
Sent from my GT-I9000 using Tapatalk

Apparently you can brick your phone if you do, and I see no reason to tick it unless your phone is having some serious issues already (I may be completely off track here, so someone please correct me if I am wrong).
You can find stock roms here:
http://www.sammobile.com/firmware/
I suggest just flashing an ICS rom straight away though, as long as you wipe data and clear cache everything should run smooth, I've never had any problems
EDIT: Take a nandroid backup before you flash anything, in recovery go backup and restore, backup to either external or internal (whatever you have more space on) and remember to copy the backup to your pc, it's located in the clockworkmod folder on your sd card when you plug your phone into your pc.

So I will flash a stock rom, download that infinitum rom and flash it to recovery? Am I right?
Sent from my GT-I9000 using Tapatalk

Just skip the stock rom part, download infinitum, reboot to recovery while you are downloading (darky's probably has a reboot to recovery option when you hold the power button, if not hold volume up + power + home at the same time until the samsung logo comes up), backup your current rom (instructions in my post above), reboot device, mount usb storage and copy the downloaded infinitum file to your sd card (don't put it in any folder, just in the root of usb storage), reboot into recovery again, wipe data/cache/dalvik cache, install zip from sd card and chose the infinitum zip you downloaded, enjoy

Yeah it has boot to recovery. I did a nandroid back up 2 days ago. I have one more question, will I be able to go back to darky's in case I don't like the ICS rom? Will try to flash infinitum. How's the battery life btw?
Sent from my GT-I9000 using Tapatalk

Yea that's what the nandroid backup is for, I'm in holidays atm so my phones plugged into the charger for most of the day, but if you search a bit other people say it has amazing battery life. (I think Slim has better battery though)
Edit: Just incase you didn't know, your nandroid backup will take you back to Darky's rom, if you want to get your settings/apps on ICS, use mybackup root or titanium backup, I like mybackup root as it makes installing apps a lot easier

Oooohhh.. So I don't need to reflash through CWM with darky's rom if I want to go back? Just a restore through nandroid and I'm back to darky's rom? Thank you.

On my personal experience, where in i have used Teamhacksung, CM9, Onecosmics and now iam on Elite ICS 10.1.
The best is Elite "http://forum.xda-developers.com/showthread.php?t=1575683"
with Midnight Hugemem kernel (BM Kernel MNICS-143LR),
which is provided with the rom in the "Actualizador" app the ROM provides,
plus flash this script "http://forum.xda-developers.com/showpost.php?p=24723427&postcount=513" for getting the 720p recording to work.
Trust me, really good combination of ROM and Kernel, Very smooth and stable.
And About Slim, it lacks many things, which if u used any other ICS rom yu would know, and CM( is very unstable as for now, but sometime later is gonna be the best one for sure.

[Q] unrooted GB - OTA ICS - Flash/Root SpeedMod kernel via Odin?

Hi good folk!
I have my son's new GN and I want to help him to safely update to ICS OTA and root.
Is it safe and possible to go from unrooted GB, do the OTA update to ICS, then flash n' root the SpeedMod kernel via Odin?
It's wipe and restore with default ICS kernel that's unsafe if I've read right?
Thanks for your help!

Ok, I sound like a total noob, I admit it!
Safest way to get speed mod kernel onto unrooted stock ics please. I have been looking, but it's like spaghetti junction out there!
Thanks!

Yup, its wiping in recovery or factory resets which is causing problems. You should be able to safely upgrade to ICS.
Not sure about the kernel. Just read the stickies. I think it would be covered.
One advice: scrap stock ROM all together.. Flash something like Asylum ICS, or some safe custom ICS ROM based on stock ROM because frankly stock ICS sucks like hell.. if you need any help, feel free to PM me!
Sent from my Galaxy Note running ParanoidAndroid v0.4 using XDA Premium. xD

The safest and easiest method would be,
1. Upgrade to ICS via OTA
2. Root with temporary CWM method here http://forum.xda-developers.com/showthread.php?t=1647148
3. Get Mobile Odin from Google Play (or search in xda)
4. Flash latest speedmod kernel for ICS (k3-5 .tar) via mobile odin
5. Reboot to recovery and do wipe from there if needed

Great! Thanks for your helpful replies, much appreciated!

i suggest you to be on gb to stay on safest side otherwise ics is a pain in ass.. go upgrade i can't stop you

+1

Anything is not safe if you don't know how to use it properly...

I don't advise you to go OTA, as if you read there are many posts are there describing battery issue, FC, unable to go to deep sleep. what are happens is likely due to previous ROM junks (thogh may not happen in all cases, b'coz there state of ROM may be clear at time of OTA update)
What i suggest best thing is to go this way
-Take backup of important data, as you have unrooted GB so you have limited scope for backup, but there is lots of applications then worth to get Root (if your RO is directly rootable) then create backup with titanium or same other application. just backup only user applications only not system junk.
-Wipe cache and data fro recovery (you can get recovery with Vol Up+home+power)
-Download ICS ROM and flash using odin from here.
http://forum.xda-developers.com/showthread.php?t=1424997
Here is installation and rooting guide
http://forum.xda-developers.com/showpost.php?p=26455511&postcount=2475
-Now you will feel fresh ICS experience. and you can restore your data which you have created earlier.
But if you dont have much application to backup, then escape root, Backup/restore steps i have mentioned. Contacts can be backup with google sync, as well from contact - import/export
and SMS can be backup with SMS backup and restore application
as well there is free appl for unroot ' My bakup" on market is good to backup these stuffs.
GoodLuck!
Edit : Yes wiping is not safe on ICS. but custom kernels are safer compare to stock. you can flash any safe kernel like CF,Franco,speedmod and some more (get it from development section) after finishing root ICS.
Just remember golden rule, avoid deleting big files, wipe and recovery function on ICS. then you are safe.

Ahh wow thanks but too late! My son started playing with his phone before I could speak to him last night, and this morning I looked at his phone and saw it had ICS. Either this phone came preinstalled with ics, or I suspect that it updated when he turned on wifi, as auto update was ticked.
So I root, flash speedmod kernel and reboot to recovery to be safe from the bad bug, then install a custom ics rom over the ota stock rom?
One question please. So I'm on stock ics from ota. After flashing speedmod kernel and rebooting to recovery, is it then safe to wipe cache and dalvik after doing this, and before installing a custom ics rom?
Many thanks again..bowled over by responses to a noob from respected xda peeps!

Okay, I'm on the Speedmod kernel and already the stock ota ics is visibly smoother. one step at a time!

Speedmod kernel is.safer.then stock.and disabled emmc erase cap command to remove brick bug. But still to be safe side avoid unnecessarily wipe as well.recovery function till that's not must. Here nobody claim 100% safe like gb kernel.

[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] I need some help to get back to Ultimate XXLSZ

I was using Ultimate ROM XXLSZ_JB_4.1.2_v5.2 without any problems apart from poor battery performance.
However, I attempted to install Rocket ROM-V1-XXLSZ and have now got myself into trouble.
I followed the instructions to flash the latest XXLSZ-OXA cwm kernel and then flashed the Rocket ROM. It worked ok but I would like to return to the Ultimate ROM and kernel I had before.
I have a pevious full Nandroid backup of the phone (made with ROM Manager Premium) of the Ultimate ROM and the PhilZ kernel it came with but cannot restore it. I get the error "MD5 Mismatch" and the restore aborts.
Even if I reflash the original Ultimate ROM with all the usual wipes, the XXLSZ-OXA cwm kernel is still there and I still can't restore from the Nandroid backup. I tried re-flashing PhilZ 3.1 kernel separately and then the Ultimate ROM file but this didn't work either. The kernel is still the same.
Can anyone tell me how to either
1. completely wipe the phone so I can install Ultimate ROM AND the built-in PhilZ 3.1 kernel.
OR
2. get the phone to the point where I can restore from my Nandroid backup which I assume will restore the earlier version of the ROM at the same time.
I hope I've explained the situation clearly enough.
Thanks in advance.
Trevor

You don't want to restore your nandroid. It is a bad backup.
In philz recovery go to mounts and storage. Format system data preload cache. Them go to advanced from main page and wipe dalvik

Thanks. I know I can flash the ROM again but I was hoping to learn why the Nandroid backup no longer works.
Since posting, I gave up trying to restore the Nandroid backup, did all the usual wipes, re-flashed the Ultimate ROM and re-installed all my apps from scratch so my phone is more or less back to normal (Incidentally, I notice that no matter how many times I do this, all my music and photos are still there even though they're stored on the internal sd card. Dunno why).
Most of the ROMs I've tried have the kernel built in so all I needed to do was do the usual wipes and then flash. If I didn't like the ROM, I just wiped again and restored the Nandroid backup using CWM (Vol Up + Menu + Power) and the phone was back to its previous state.
The only thing I did different this time, as per the Rocket ROM instructions, was flash a kernel first. I may have done something wrong with that step or messed it up somehow. Even when I flashed an earlier version of the PhilZ kernel, the restore still didn't work. I've still a lot to learn about ROMs and Kernels, I guess.
As I said, I have successfully restored from Nandroid backups many times before this without any problem after experimenting with different custom ROMs. Can I ask you why Nandroid is a bad backup? Is it a problem with ROM Manager?
(One problem I've always had with ROM Manager is that if I choose to write the backup to the external sd card, it falls over with error messages. If I choose the option to backup to the internal card, it works but writes the BACKUP TO THE EXT CARD ANYWAY! I cannot get a reply from the dev about this).
Is there a better, more reliable backup method you'd recommend that does the same thing as the Nandroid?
I notice that different ROM managers use different CWM Recovery versions ie ROM Manager Reboot Recovery = 6.0.1.2, ROM Toolbox Rebooter = CWM 6.0.2.8 (same as Vol Up + Menu + Power). Could that be part of the problem?
Sorry for the long winded post.
