[Q] Nandroid Backup Question

Can you use a Nandroid backup across any ROM, or is it specific to the one you backed it up on? Sorry if this seems like a dumb question... I just switched ROMs cause I'm trying a few of them out, but for some reason it's saying my SIM card has no contacts. I'd also like my SMS's back too. THanks

I think so, wait for confirmation as I'm not 100 percent. But I do believe that is one of the main capabilities of a nandroid.

@OP:
Nandroid backup holds good ONLY for the ROM u flashed.
1. Flashed ROM 1
2. Took a nandroid backup
3. Cleaned and flashed ROM 2
At this point, the nandroid backup at step 2 will not hold good for ROM 2. If u restore it after step 3, u'll get back to ROM 1.
If u want internal stuff like contacts, etc, u got to use an app like TiBu.
1. Flashed ROM 1
2. Took a backup of user apps and data with TiBu
3. Cleaned and flashed ROM 2
4. Restored user apps and data using TiBu
For contacts, u wud need to back up and restore system data (only) "Contacts and Storage". This is the only system data I have been able to successfully restore across multiple ROMs.

Do I need to be flashed to that ROM to restore a backup of it? I've been getting stuck at the HTC loading screen, and after using HBoot or w/e and returning to stock, tried using CWM to restore from a backup. Do I need to flash RCMix3D ROM before I can restore from the backup made from it?

Restoring a nandroid backup from rcmix3d will put you back to that Rom with all apps and data you had at the point you made the backup. If you are restoring apps and data using titanium backup, you will have to flash rcmix3d first.

I thought so too, but all it's too is getting me stuck on the HTC boot screen. Been like that for 20 minutes so far. Dunno what I did wrong, but I'd like to get everything back to the way it was

A couple of my backups refused to flash. Do you have more than 1?

I have two for each of my ROMs, so four total. Created days apart though.

Do they all hang when booting?

A nandroid backup makes a complete copy of your phone as is when you perform the backup, obviously this includes the rom you are currently running.
If you are running rom A and do a nandroid and then flash rom B, and then restore the nandroid backup you previously made you lose everything you've done since the backup and you are back where you were on rom A when you did the nandroid.

Check out if both are EXT4 compatible.
ROM 1: EXT4 not compatible
ROM 2: EXT4 compatible
1. Flash ROM 1 (formats to non-ext4 and flashes ROM)
2. Nandroid backup of ROM 1
3. Flash ROM 2 (formats to ext4 and flashes ROM)
4. Nandroid backup of ROM 2
...
5. Restore backup of ROM 1
This could fail since partitions are ext4 and ROM 1 is not ext4 compatible.
Here is what I do as a standard before restoring any backup:
1. Data/factory wipe
2. Dalvik cache wipe
3. Restore ROM
This worked all the time, except once when I got MD5 error (probably cos I backed up on an earlier version of CWM, not sure though).

@biglittlegato
Yeah, they all hang on the HTC screen. It's starting to piss me off. I know that it's a risk with rooting and stuff, but I'd rather just not have to start all over with my content.... again. I just flashed a clean RCMix3D, so maybe it will let me restore my backup from that.
@Perseids
That kind of thing may be obvious to you, but not to those of us who are new to Android and rooting. Hence why I was asking in the first place. I get that I'd lose everything I haven't backed up... but right now I seem to have lost everything period, as none of my backups want to work for some reason.
Maybe I am doing it wrong? After getting to the stock version of 2.2, I go to ROM Manager, and then to manage backups/restores. I click on that, then hit the backup I want to restore from, and it's supposed to work. It does it's thing, then just freezes on the HTC screen once it reboots. I watched it and read the script, and there were no errors or anything that would give an indication as to why it's doing that...

Thanks for the help.... but I have no idea what this means haha. I get the basic idea, but I don't know what ext4 is.

Don't worry too much. EXT4 is a partition type. Most recent ROMs support this. Just make sure in the ROM thread OP if it converts partitions to EXT4 (if yes, what all partitions).

I was just reading the script while it was (trying) to restore, and it said something about erasing boot before restore... is that normal? I just did a full wipe, flashed to the ROM I did the backup from, and the backup seems to be stuck again.Dang.

Restoring process erases everything, and restores. Compare this to norton ghost partition restoration process.

I guess I might as well just start over from scratch. It was only a few days worth of pictures/videos/texts and stuff, so not a HUGE loss. Still, wish the backups had worked as they were supposed to. As of right now it's still frozen on the HTC screen hah.

Data on SD card will NOT be deleted unless u choose to format SD card. All ur pics, vids, etc reside on ur SD card.

It doesn't show up anywhere. I just booted into CWM, and tried to select one of the backups, but it said "no file found". WTF. Sooooo it's telling me the backups are there, but don't contain anything I think. Nice.

If you're backups are not restoring you will lose data that's part of the ROM. Your pics and videos would definitely still reside on the SD card. You'd have to format SD to lost those.

Just bootlooped my phone

I was turning off voodoo lagfix to prepare for humble 5.0 and when restarting, the phone will not get past SAMSUNG. I am running gummy FE 2.0 and I went to the voodoo control app. I disabled lagfix, and it won't do anything. I haven't heard the female voice at all, either.
I realize that I can just flash over it. However, is there any way to just flash over /system? I would really like to keep the data partition intact.
EDIT: I got it booting into CWM. I tried a simple wipe cache and it didn't do anything.

LOL! I flashed imnuts pbj kernel just for fun because it was on my sd card. It did not boot up. Then I tried to boot up into cwm and got the voodoo lady. Will update briefly

OK I successfully got RFS on my phone but it still wouldnt boot. I had to go to class and I got bored so I flashed gummy fe 2.0 which formatted /system and installed. Still wouldn't boot. Then I went and manually formatted /system and went to Advanced restore. I had a backup of one of my original froyo before i messed with custom ROMS so i restored just /system. It booted up and I backed up everything in titanium. EP4 here I come!
For future reference, can I pull files out of the nandroid backups that CWM makes after I get them on my computer?

no not yet but I hear there is development on an app or something that'll let you do it but it only works with CWM version 5+

I looked on my sdcard and it looks like each partition (boot, system, data etc.) has its own .img file for each nandroid. So if they made such an app, it should work for all .img files, right?

Did you try clearing cache and delvik in recovery?

If you can find an app that can extract .img files then you can open those up. Should be one on the market somewhere.

[Q] about backup,CWM restore=titanium restore?

The question is :
restoring "USER APP" from a backup made with clockworkmod,is the same thing than restoring from titatanium backup?
I'm talking about user app and not system app, and i know that titanium let you choose what you need.
Thanks!!!

CWM only lets you restore everything in the "Simple" mode (that is, format all main partitions and replace with the backup). If you click on advanced restore you can do the same for a particular partition, such as just /data which would essentially do what you just said.
Now i've not tried doing this via CWM, but i can easily see this leading to problems. I would use NANDROIDs only to do full backups or advanced restore only if you are using the exact same ROM as the backup. Otherwise, probably best to save the trouble and stick with Titanium.

Usually i flash cm9 kang every day,so i assume that restoring from cwm advanced restore should works without problem.

It most likely would work perfectly fine in that case. Though you can probably just wipe everything besides the /data partition to begin with and just flash the new ROM. Why wipe /data just to flash the same /data?

i'M AN IDIOT...YOU'RE RIGHT
But the doubt is inside me and sometime i like to try different rom...how can i open "data.img" from cwm backup?
i would like to see what exactly is inside.

I believe it is a yaffs image file. I've not tried to open it but maybe have a look around for unyaffs. Might be easiest to do it in a linux environment, i think there are some native tools available.
However, it is likely just an exact copy of all the files in the /data partition, you're not missing out on anything root explorer doesn't already show you. This means the dalvik cache is in there too, so it might be best to wipe that separately every flash, especially if you decide to restore data via CWM afterward.

I had a look inside root explorer...i wanna try
I think it's the best way,if something goes wrong i'll still have my nand bkp

i tried and seems everything works fine:
start with cm9kang
-nandroid backup
-wiped all
-installed "codename 1.4.0"
-restored from kwm advanced only data
-wiped dalvik
-installed gapps
some settings have been restored,other no ,and all app works
I'm wondering now if codename is cm9 based rom

multiboot CM7 to Froyo

i may go back to froyo for a weekend, going to a 24Hour GT race, would like everything working properly, vid, cam etc. basically nice and stable.
if i multi boot to froyo do i have to wipe cache/dalvik cache and sd ext. sd and sim inserted or not?
tried this before, ended up with continuos fc of apps when i inserted my sd card.
anyone give a step by step, and how to restore back to CM7?
(secretly hoping CM& is sorted by then, well, we can hope, eh?)

For g3mod,
Use kmapp by rapier07 to configure your multiboot settings
Enable multiboot
Enter recovery backup img and flash the froyo ROM img via multiboot
This will automatically backup your current ROM erase system, cache,etc., and flash froyo on your ROM
If you want to revert back to cm7 just flash the img you previously backuped.
Alternate:
Enter recovery backup everything
wipe everything except sdcard(wipe sd ext)
Flash img or update zip
When you want to revert back to cm7 just restore previous backup
and everything will be back
You will definitely get fcs if you don't wipe sd ext while using second method
In first method you don't need to do anything extra

nice on allspark
first option seems the best i have KMApp 1.4.1 installed, but i cant find the multiboot options, data-kernel-tweaks and data conversion using menu button available.....
edit-running G3MOD 2.5 Kernel, forgot to say.

Didn't you find multiboot in data preferences . I think you find it right away on the main screen
Enable multiboot
If you don't try 1.3 which same great features
I can't confirm this as I am on fugumod and cm9 (not supported)
Edit: sorry dude
It is multiosdata
Sent from my GT-I5800 using XDA

use option 2 then!

@Skivit
Check my sig for multibooting...it's all there....but with g3mod 2.5 multiosdata ain't working somehow....dalvik gets wiped when u switch rom....automagicaly....only thing u should do is data wipe when switching to froyo & restore froyo data from multiboot....any [Q]?....just say

if i hit problems, i'll give you a shout!

If all the data in your phone is really very important then also have a nandroid backup in case multiboot fails
Also copy your contacts to sim using contact2sim or save them on your sd card just in case anything fails
Multiboot, nandroid backup and every possible way you try to backup data are extremely unreliable and I lost so much of my data lots of times believing they would work

well....i never lost anything with multiboot.... you don't need full nandroid backup coz "backup_data" in multiboot is working perfectly....and only thingy is that due to multiosdata not working properly(e.g. data partition never gets restored)...so you have to format data & sd-ext partition before restoring other OS data to avoid any fc's due to overwriting data over existing data....that's all....otherwise it's safe...

[Q] Bootloop after restoring Nandroid Backup

So I recently flashed Paranoid Android based on Lollipop 5.1. Everything was working perfectly but I decided I wanted to flash Xperience kernel. I did a nandroid backup first. I flashed Xperience. After going into a bootloop I went back to TWRP to restore and retry to see what I did wrong. After restoring I am cought in a bootloop again. What should I do?

Try wiping cache and dalvik cache.

Already tried that. I already got it to boot but I lost all my apps and stuff so that sucks. I am still trying to make the restore work because I am lazy about downloading everything again configuring and personalizing my device again.

have you backupd all the stuff (/data /system /boot ) ??? thats really all that need. wiping cache means no real data loss. if yes, then wipe the phone complety( format /sytsem /data /cache /dalvik /internal storage) (maybe copy internl storeage on pc 1st) to make sure all is fine from phons side. after that restore your backup completly but without restoring cache & try to boot.

I did not backup everything. I only backed up what was checked by default on TWRP so that is probably it. Thanks.

i think TWRP atleast backups /system , /data & /boot maybe u check it? (you can tap on cutom restore or look in the backup folder to know whats bacupd)

Damm I am so stupid. Apparently I accidentally unchecked boot so it wasnt backed up. That is most likely the reason why I am not booting.

Ok then its easy. Wipe the Device, install only the Rom which has the needed kernel, Boot it once, then back to recovery & restore System + Data. Done =) good luck
Btw /Boot is the kernel. So you never restored your old kernel and spirit bootlooped like you say...
