Hi Guys.
Well, first of all, before someone jumps in and yell at me for such a question, I apologize in advance but I already know that is impossible to do it, but I still have some doubts about what could be some possible solutions for my problem.
In resume, I had my Captivate with Eclair 2.1 Stock rom, I wanted to use CM9, so I took KK4 Stock Rom from this post http://forum.xda-developers.com/showpost.php?p=18370912&postcount=3
as requested in the CM Wiki - Captivate Full Update Guide, then flashed mtcarey's Kernel with the ClockworkMod Recovery 5, at that step, before flashing CM9, I made a Nandroid Backup just in case something went wrong, and also because I liked GB, I used GB for about 2 days just to give it a try, then I flashed CM9 and everything worked great.
Now, I have made a Nandroid backup of CM9 too, both backups are in my PC too; And here it comes my problem, I know I cant use CWM to restore KK4 Nandroid Backup, cause I already tried and It throws me an error flashing boot img, and end up in a boot loop, (I think that's pretty normal isn't, Things we need to do to learn ), also, don't know if that's because different CWM versions, cause CM9 comes with a newer version of CWM than the one of mtcarey's kernel.
So, Is there anyway I can take the Stock KK4 Rom and make it CWM compatible?, Or everytime I'd like to get back to GB I'll have to do all the Odin thing, flash mtcarey's kernel again, and then use my Nandroid Backup to really get back, and then keep making Nandroid backups to keep updating my Roms.
BTW, I don't care about apps, Call logs o SMS; I only care about contacts and I have them all in my SIM; And again, apps are ok cause Nandroid backups cover them, and I don't usually have that many apps, just the necessary ones.
Note: I'd like to Switch between this Roms cause, I really like the look of GB, I prefer the Camera app too, and in the 2 days I used it, I don't know if It's just me or not, but I found GB handling my battery more efficiently; And Of course I like CM9 cause has more settings to edit, more customizable, etc.
Thanks in advance!
PS: Sorry I Didn't notice I can't post Questions in this section, can some admin move it to Q&A section? Would be very appreciated.
Once u r running CM or similar, in order to go back to GB Stock firmware or Roms based on that, you must use Odin or Heimdall to flash back to GB...because the partitions are different. Stock firmware = BML/rfs partitions and CM, AOSP, AOKP, MIUI and such like = MTD/ yaffs(2) partitions.
Flashing from GB, froyo, or eclair to CM or the like only requires u to do full wipe and then flash the Rom twice in CWM...first flash in ur current cwm. second flash of rom in that rom's cwm recovery that comes up from first flash.
U can only restore nandroid backups when u r back on that Rom u were on when u made the back up. And u need to be using the same cwm recovery/ kernel u were using when u made said backup.

Many Thanks man, well that entirely clear my doubts, I suppose if I just keep using both Roms time to time, of course It wont be every week but so much time more, I just need to keep my Nandroid backups of both Roms, to do all the back-to-stock-flash-again thing and restore the backup and continue using the rom from where I left it... or in any case, switch from CM9 to anther custom ROM... from now I'll stay in CM9 till CM10 reach an stable version.
Again, thanks man, really appreciated.
No prob. :thumbup:

I want to try some kernels for cm 7.1 to see if ocing could help speed up some games. If I don't like them I would like to get stock kernel back and I know I can't use sgs kernel flasher to back up current kernel because cm7 is different. I think I read that you could do a Nandroid and this would back up the current complete setup. Is this true? (sorry can't seem to search efficiently on this Tapatalk and don't have access to a computer). If so does it also backup apps, data and all? Is it done on the backup rom from rom manager or recovery? Thank you for your help.

nandroid backs up everything just as it is. definitely use cwm not rom manager.
you could also just put d/l the stable kernel as a cwm flashable zip.

nandroids do not backup kernel or modem.
have you ever made a backup of one set up and tried to restore onto a completly different rom? well if you have then you know there is a high chance that it will bootloop because of a now incompatible kernel. the procedure for a proper nandroid restore is to flash the rom it was backed up on (thus flashing the kernel that is compatible with it) and THEN restoring the nandroid. then it will be like you never flashed away from that rom at all. (this is speaking of tw roms as i have never run an aosp so i could be mistaken about it not backing up kernel on cm7)

Trying to create a nandroid backup in cement v4... (running uckj3, with boog's kj3 kernel) and every time i boot into recovery and perform a backup it gets stuck at "backup sd-ext" kinda confused as to why this is happening, also can't get the kj3 extended power menu to work, flashed the zip maybe 5 times, cleared the cache/dalvik cache and nothing, any and all suggestions are greatly appreciated. Thanks guys.

The nandroid backup is not yet working in the Gingerbread Roms.
The extended power menu is for Deodexed Roms only.
Hope this info proves helpful.
update
Okay, so I was thinking about why it wasn't working and went to my clockworkmod folder on the SD and saw that the files were pretty large in size, all totally over 4 FBI, so i deleted some miscellaneous files to free up some additional space and tried to run cement backup again... still took a while and did think it got stuck again, but it actually finished..could i safely assume that it worked or should i not trust the files? Also, the more i think about it, do i really need a Nan backup? Meaning, if anything goes wrong with my phone i can always reflash stock and use titanium backup to restore my apps...any thoughts?
Like I said before, the Nandroid Backup does not work in the Gingerbread world. It may look like it is backing up but the restore part won't happen. If u try u may soft brick.
And yes, the fail safe is that you could always return to a Gingerbread stock of your choice and use Titanium Backup to restore your stuff.
nandroid works on gingerbread, just not I897 kernels. I9000 works fine.
although i don't use them personally.
^ Thanks for the clarification. I didn't realize that about the i9000 because I am always on i897.
It's amazing what is being accomplished on captivate kernels, reverse engineering and building "blind" but nothing beats having source code to work with, which is why the I9000 nandroid works.
So how can I tell if I'm running an I897 or I9000? Currently using UCKJ3 with boogs kernel and just flashed the samurai kernel
Sent from my SAMSUNG-SGH-I897 using XDA App
that is I897.
I897 firmwares usually start with a K
I9000 usualy a J
it will also usually say in the op of the thread...
I am currently using the latest RocketROM V7.
I wanna know... if I am to backup and restore a ROM with ClockworkMod Recovery... how should I do it?
I flash Abyss Kernel 4.2, reboot recovery (so I am in the CWM modified by Abyss), backup the ROM... and when I wanna restore, I do the same?
If that's the way to go, when I restore, I'll have Abyss Kernel 4.2, and not the one that the ROM has... Erm... Can somebody shed some light?
I'm asking because I'm aware of all this talk about the eMMC bug (and the fact that it actually exists), and since CWM formats the internal memory... it'd result in a hard brick, haha...
if you backup on Abyss kernel you will be on Abyss kernel AFTER the restore, So ideally you should flash abyss BEFORE restoring, and then change the kernel AFTER (if you want to)
The brickbug is not to be taken lightly, Its a serious issue, so if you have to do things a certain way (I have a ritual for wiping lol) and it takes a little longer, So be it, at least you know you will be safe.......ish

Hmm... so... forget about RocketROM for now.
Let's say I am on Half-Illusion, which has two kernels (optionally) : CM and AOKP.
-flash jBroid's Kernel Cleaning Script.
-flash Abyss 4.2 kernel.
-reboot recovery.
-backup.
When I restore, I do this :
-flash jBroid's Kernel Cleaning Script.
-flash Abyss 4.2 kernel.
-reboot recovery.
-restore.
-flash desired kernel.

Dont forget that your backup will be a GB ROM, so you cannot restore it if you venture on to TW ICS ROMs ! But im sure you knew that anyway !
Other than that, Your steps are spot on !

What I mean is, if your now on a gb rom such as cm9 or aokp And you create a nandroid backup, that backup is going to be a complete clone of your current set up. So you cannot restore that nandroid on a Samsung ics rom you can only restore it on a gb rom

I didn't know AOKP had GB builds, too...
Anyway. I know what a CWM backup is, I've been in the Android world since exactly 13 months.
What do you mean I can't restore that NANDROID on a Samsung ICS ROM? As far as I know, a CWM restore erases all the contents (system, data, cache) and restores the respective data from the backup... so it's not like it would OVERWRITE on the current TW ICS ROM, for example.
What I wanna know is... I can back up everything, except for the kernel (since I'd flash Abyss 4.2 w/ recovery), and when I restore, I flash the kernel manually. That's all there is to it... right?!
When you are creating a backup...just drop into CWM and create backup. When restoring the backup you can flash the Abyss kernel first > reboot recovery > and then restore. So now when the restoring happens the kernel which was in your rom will automatically get restored and abyss will vanish once rebooted.
@azzledazzle CM9 is ICS and not a GB rom I know you know this and u just slipped your fingers while typing ...but just correcting so that no confusion arises to other readers
And if you are on any CM9 based rom or any AOKP based rom which is based on CM kernel then you dont require Abyss at all. Just forget about it when on any of the roms.
Hope this helps!
Cheers!
Yeah I know its an ICS ROM, But dont you have to be on GB to flash it ? What I mean is you cant flash it from Stock Samsung ICS can you? (thats how i understand it anyway)
And I didnt know CWM erases partitions, I thought it just overwritten the existing ones, Hence why I said dont restore a GB (AOSP ICS) on Samsung ICS (if that makes sense?)
But I guess ive learned something new from you Hopefully I can pass this new found knowledge onto someone else lol

Yeah you cant directly flash the CM9 or AOKP based on CM kernel directly over the Stock Samsung ICS. Its a sure shot brick you have in your hand if you do that. The stock ICS kernels cannot handle the "format" command in the updater script, CM is working on trying to use delete_recursive instead but still its not complete fixed. Hence you have to be on GB or on GB kernel (like Abyss) if you want to flash the CM9 based rom.

Oh... you're right, lol. Backing up doesn't format/wipe anything. Only restoring does .
But... the CWM I have right now (was flashed among with RocketROM) is a different version, non-touch-driven, than the CWM that is included in Abyss 4.2 kernel (touch-driven). Are backups compatible?

So... you're saying that both CM9 and AOKP kernels have the eMMC thing removed, so wiping data when using those kernels is safe?

The CWM you have with RocketRom comes from the kernel of ICS which is included in the rom. The Abyss 4.2 is a GB kernel hence it has it own touch recovery. Not sure what you meant by - "Are backups compatible?"
So... you're saying that both CM9 and AOKP kernels have the eMMC thing removed, so wiping data when using those kernels is safe?
Yeah its perfectly safe wiping data on these kernels.

What I meant by "Are backups compatible" was... are backups made with the CWM that comes with RocketROM (not touch-driven) compatible with the CWM that is included in Abyss 4.2 (touch-driven)? I mean... can I restore the backups made with one CWM, using ANOTHER CWM?
I always forget their versions...

I mean, we already got 4.0.4, and that didn't fix it. The next update is probably going to be JellyBean (if we even get that officially!), some 5+ months from now on :/
This brick bug is utmost retarded. I mean... on the Note, and recently, on the SGS2 as well... they're either stupid, either it was on purpose - to prevent at least some devs on working on those devices...

Hi , some questions.Will appreciate if anyone could take the time and answer.
1. What things are left out in a nandroid backup? Are kernels included?
2. I can't restore a nandroid backup of froyo on GB without flashing a stock froyo build first, is that right?
3. Can I restore a Nandroid backup of GB 2.3.3 (say) while on GB 2.3.7 or any other 2.3.x? If yes, what if I am on different kernel than the backup kernel, can i still do it?
4. Suppose I am on 2.3.x based custom rom (say MIUI) and I restore a 2.3.x based CyanogenMod Nandroid backup, will I get my whole CM back or all my apps/settings of CM on MIUI?
Thanks a lot.

I'm not sure I can answer all your questions but I'll tell you what I've done.
From stock, after making a nandroid backup using CWM, I've flashed a CM7 having done all the usual wipe(cache,etc) procedures and gone back to stock using the backup. Everything is restored, including my settings, old messages, kernel, apps, everything. Be warned, you will obviously lose all the messages and call records that you received after you flashed the new ROM, unless you use an SMS/call log backup app. Same with CM7 to CM9 and back. So if you plan to flash a new ROM, the nandroid should be able to get you back to the exact same state that you were in when you made the backup.
I'm not much of an expert though, so I might be wrong. Feel free to improve on this answer!
1) Yes
2) Yes. Because of change of Linux kernel version.
3) Yes.
4) You will get whole CM back!

One more question.
As you said, since I can't restore a backup of froyo on GB (because of linux kernel change), how can i restore a 2.3.x with a different kernel on a different 2.3.x with a custom kernel. Or is this kernel different from a linux kernel?
Asking because you answered the b part of 3rd question as yes (or maybe you didn't answer it at all, i am implying here)

Cant restore my contacts,sms,apps and data from Gingerbread nandroid backup
Hi,
I have a similar problem.
Thought of posting a new thread but afraid that i would flood the forum.
I have taken NANDROID backup of my Gingerbread Stock ROM(rooted) using CWM.
Currently im in Cyanogenmod 7.2 for galaxy ace S5830.
I thought of restoring my Contacts,Sms,Apps using Advanced restore from Recovery mode.
Result: "MD5 mismatch" hence unsuccessful.
I tried restoring my Entire NANDROID back up.
Result: The Ace was stuck up with Samsung LOGO.
I flashed CM7.2 again after restoring factory settings.Things work but a blank phone.
So im in 7.2 again. How do i restore the GB Rom? I just want to safely export Sms,contacts and data using .APKs and retrieve back in CM7.2 ????
(BTW CM 7.2 gives me 2 days battery backup at 480 Mhz (underclock) with many useful apps customized as ROM. Quite Delighted. Thanks to Mclaw)
Custom and stock roms use different file systems. Custom uses ext4, stock uses rfs. You need to convert file systems before restoring backup.
Ways to do it:
-flashing stock firmware with odin.
-using the cf-root ext4 manager app, which you can extract from cf-root flashable zip.
Good luck
Hey Guys,
I have a rooted LG p990 from FIDO in Canada. I was wondering if i can get back to stock rom in order to get the ics OTA update.
I have NOVA HD REBUILD 1.1.0 (unofficial cyanogenmod 9) on it currently with the 2.6.32.59-HP-CM9-ICS-SUPERSONIC-RC2 Kernel.
I also have a nandroid backup of GB, but dont want to backup because i read online that the kernels are different and something to do
with the file system so you can brick your phone. Can i just restore the nandroid? or go back to stock? and how?
New to flashing, ROMS, Kernels etc. so i need help
You can restore the Nandroid without any problem. Everytime you change the ROM, Kernel will also be changed along with that. So after you restore the nandroid backup, your kernel will also be changed to Stock Kernel along with ROM. There wont be any problems.
Press THANKS if my answer is helpful.
If you are in Canada then I don't see how you will get ICS ota when LG Canada have said they won't release it there.
I doubt any release of ICS will be ota.
You'll possibly need to flash a downloaded rom to ICS anyway. Not sure if just changing regional settings will work but someone else can chime in on that one.

Are you sure, because i read online that ics changes the file system rendering the nandroid backup useless. And finally I don't need to flash a gingerbread kernel before right?, as nandroid restores my stock kernel.
Stock kernel is a gingerbread, one

Yes... The nandroid restore will restore the stock kernel as well. I have tried a few ICS Custom ROMs and restored my Nandroid backup and it restored the stock kernel.
One more question
Will the nandroid backup also restore the stock baseband and RIL?
Help - boot loop
I did the restore and it restored successfully, but when i reboot im in a boot loop and cant get past the white lg logo! HELP
FIXED
Changed to ext3 file system and it works now

You can restore the Nandroid without any problem. Everytime you change the ROM, Kernel will also be changed along with that. So after you restore the nandroid backup, your kernel will also be changed to Stock Kernel along with ROM. There wont be any problems.
Press THANKS if my answer is helpful.

Yes. Download a stock image from xda threads and flash it. You might have flash a new kernel if your coming from ics.
