Nandroid Backups? - Nexus S Q&A, Help & Troubleshooting

Ok, this is a weird question and I know i'm probably just overreacting but when you restore a nandroid is it just like how you left the rom? I believe it goes slower once you restore it but I think i'm just overreacting as I said? Is everything the same no problems and is it like a reboot thanks!

It restores to the status your phone had when you did the backup. A nandroid backup is more like flashing via Odin (or pushing .img files) to your phone then flashing a custom rom. If it's going slower then before try to wipe before restoring, and fixing permissions after.

I personally never found the Backed up ROM slower than the usual one. Though clearing the cache never hurts.

Constant FCs after every Restore

Ever time I do a Nandroid restore or through CWM, if I go to even my most recent backup (last night), as soon as it boots, I get a lock screen with a black background and TONS of FC messages. I have several backups from Stock Root, Docs Rom first flash, etc. None of them ever restore properly in neither Nandroid nor CWM. Anyone else having this problem?

Did you see any error messages during your restore? Did you have a lag fix before you tried a restore?
No error messages during restore. I had a lagfix applied to my newest flash, but was not applied to any of the backups. Would that still cause all the FCs?
I had this happen before as well. If you were running a lagfix, or changing between Froyo and Eclair, your backups might just be incompatible. Besides, sometimes backups get corrupted.

The Nandroid backups have issues. If you made a backup with lagfix enabled, I don't think it is restorable at all. If you disabled lagfix, it is probably restorable, but not directly.
It seems that the nandroid backup of the captivate does not backup everything.
I found that after I restored a backup, I still had a kernel that I had not backed up.
So, If you want to get back to the nandroid backup, I think it will be multi-step.
Probably safest is,
Flash Stock Odin, clear data and cache.
Flash the rom version that your nandroid backup was made on.
Disable the lagfix, if there was one
Restore the nandroid
Restore the lagfix, if there was one

I have noticed issues if you go between i9000 and captivate roms as the file system is slightly different. You may have to "adb shell", cd /data and rm -r dalvik-cache as well to make sure that it is cleared. It will make the initial boot MUCH longer, but it takes care of that compatibility issue better than CMW does with not being able to find the dalvik cache on SGS phones.

Weird issue with NVFlash

Hi,
I have the nvflash recovery thing on my G2x and there is this very weird thing that happens that I was wondering if anyone else experienced.
The first time I flashed the CM7 I backed up the whole thing and restored and everything was fine. Then I did some stuff and backed up again except this time when I restore all my apps are gone and none of the widgets work so I restore the first backup again and everything is fine. Then I add all the stuff I added on stock and backup again. Then I restore the new one and the same thing happens but when I restore the first backup everything is fine.
Am I doing something wrong? Or has anyone experienced this before?
Are you performing a WIPE before you restore from the NANDROID Backup?
When ur backing up the rom u don't wipe anything rite? Just go into recovery and backup? Cuz ur not supposed to wipe anything just go in and backup
Yes, I am performing a wipe before I restore and no I'm not performing a wipe before the backup lol otherwise there would be nothing to backup
I have a updated g2x (gingerbread via Lg updater) installed NVflasher was able to boot into recovery performed a nandroid back up did a full wipe and was going to flash Xbroarders rom until i relized i put it on my internal instead of external so i then tried to flash my back up and got "no file found"did a reboot and all im getting is a black screen wit flashing keys. plz help

[Q] Need reassurance about backup process

Hi. I've been using a ROM for the last little while (SlimICS), and I like it, more or less. There's a feature in another ROM (ParanoidAndroid, per-app density), that I'd really like to try out, but this ROM also has a lot of features I don't want (tablet mode) and doubt I would like. I use TWRP as my recovery...if I use TWRP to make a backup of System, Data, Boot, Recovery, .android_secure, and EFS, will I be able to flash this other ROM, then restore the backup to go back to my old ROM after I play with the new one a bit? Will the backup of these items bring me back to exactly how it was before, if I do a Wipe Cache/Dalvik Cache/Factory Reset?
Sorry if these questions are answered elsewhere, I'm just trying to make sure that my limited understanding of all this isn't incorrect, in my specific situation.
If you make a backup through recovery, when you restore, it'll be exactly where you left off, settings and all, when you shut the phone down.
When backing up in Recovery, you are backing up the OS and apps. This is called a nandroid. This does not backup anything on the sdcard.
Yesterday, I flashed a different kernel version on my NS. Before flashing, I did a nandroid backup using Reovery. Unfortunately, the kernel failed to load properly and I was stuck in a boot loop. I restored my backup I have done previously, and my phone was back where it was, few minutes before. It is very easy to do and backups/restores and verified using MD5 checksum.
Keep in mind that some apps put stuff on the sdcard. So if you flash your phone to a new ROM, upgrade apps and then go back to another ROM, it is possible that some apps won't work anymore. I've never seen this happen but this is a possibility.

Restore TWRP Backup?

Hi, just have a quick question that's been bugging me for a while now. If I have made a full backup using TWRP and I want to restore it, should I:
Fully wipe system and caches and then restore; or just restore right over my current ROM?
****, good question

Restore takes care of wiping for you.
Piggybacking off the OP, sometimes when I try to restore my TWRP backup it fails, and then the only way I've found to get it working again is to do a boot loader factory reset, and then essentially start from scratch or load an older working backup. No problem, just a minor annoyance. Is there something I'm doing wrong or any advice someone can give me?

I always wipe everything before a restore, just in case
Better safe than sorry
Restoring a back up !
When restoring a back up from any recovery wipe everything just as if you were installing a new rom. Factory reset, cache, dalvik cache, system just to be safe. Factory reset wipes data and all cache but not system and if you do a factory reset and then try to wipe I think dalvik again you get an error but no harm done it just will not do it again. I usually do them all and then do the superwipe zip and that willl give you a good piece of mind that it is properly wiped. Also, I have noticed that using the external sd card seems to work best for installing roms or backing up and restoring back ups or anything else like mods or themes. Here is the superwipe zip in case anyone needs it.

I've done both, but I like not having reinstall all my apps, and reset all my ringtone, and that goes with a full wipe. so when ever i can i flash over. Just make sure your slashing the same rom over the old one.
You shouldn't worry about losing ANYTHING on a backup when you do a factory reset, because the backup houses all of the data and settings anyway.
All you do is Factory Reset, Nandroid>Restore, and your old backup will flash everything the way it was when you did a backup in the first place. Factory Reset is always wise, especially when you're fiddling with different ROM's based on different kernels or systems (AOSP/Sense).

Ahh, this is true I recant my statement. I was mistakenly thinking about flashing a new ROM over an older version, not a buck-up. I feel stupid.
when restoring a nandroid if you've got the new HBoot I think you have to restore boot.img separately via fastboot. Is that right?

Nope. I just flashed a bunch of roms yesterday and did restores with no issue. I think if your using the stock rooted 2.2 you are correct, but any other rom a restore works fine.
Not Restoring = Bad Idea

I have made the mistake of not wiping everything (excluding sd card) when changing ROMs or when restoring from a backup. This may be a little different because it was when I was switching to a new ROM on my brother's phone, but I tried to take the lazy way out and not restore everything. I really didn't feel like redownloading everything. I soon learned that this was a mistake, and his "phone" app suddenly disappeared. He was also unable to send or receive texts. This soon made the process even longer than I wished it to be because I needed to go back and restore everything again and get it back to normal.
Error While Restoring using twrp
I took a back up of everything using TWRP and then when i tried to restored its giving me error while restoring system E:Unable to extract tar archive . Please help
Are you trying to restore a backup from a different version of TWRP? For example, currently running 2.7.0.8 but backup was originally made using 2.3.3.1?

WOW! After a good 3/4 days of frustration, thinking I had ruined my device, I finally got my TWRP backup to restore.
It's my first time using this software and the restoration process is truly amazing. I mean, my test messages were still there, even my browser history and last page loaded up in chrome were still there. I'm blown away.
The strange thing is that It didn't work when all 3 partitions were selected. When I tried it this way (as per the many step by step instructions that I read) my phone would load up a black screen with just the notification bar visible. I'd see my voicemail, sms, wifi and battery icons at the top, but absolutely nothing else except for a myriad of pop ups that read 'Unfortunately [app name] has stopped working'.
So I bit the bullet and did some trial and error with the partitions.
Turns out that when I only selected 2 of the 3 (I believe they were 'Boot', 'Data' and deselected 'System') everything loaded up just as it was before the backup, except there were only the stock apps available and no google services at all. .....Very odd.
So I did the boot to recovery method before turning the phone off (vol. up - Home - Power) which restarted the phone and strangely brought back EVERYTHING as mentioned at the start of this post.
You can probably understand my confusion here and while I'm VERY happy that it all worked out, I don't understand why it worked with only 2 of the partitions but not with the recommended 3 of them?
Can anyone shed any light on this?

Hmmm. I'm definitely no pro at this stuff, in fact i'm very new when it comes to using TWRP, but this is what happened with me.
First of all, the backup that I did was simply a folder of files, not zip.
Transferred that do my PC, wiped my phone with TWRP and replaced the backup folder back into the TWRP/Backup folder. However, after reading up on how to restore on about 10 different android sites/forums, only 1 post shared the most vital piece of information.
You folder has to be in the 'serial' number folder that's located in the 'Backup' folder for TWRP.
When I put my backup folder just into the TWRP/Backup folder, the Restore section would only see the folder itself but the partitions were not available/listed for selection.
Once I placed my Backup folder into the TWRP/Backup/e1oog75 (that alphanumeric name is just a random example made for visual clarity) folder, my partitions were visible and available for selection right away.
Hopefully this helps somewhat.

[Q] General Nandroid question about restoring a backup and custom kernels

Hi
I have a couple of questions, been digging around xda and the web and found some conflicting answers...
1) Does a Nandroid backup also back up the kernel? I'm thinking about dabbling with some custom kernels, but don't want to potentially mess things up as well as have an easy way back to the stock kernel if I don't like the custom one for one reason or another.
2) What would happen if I made a Nandroid backup from recovery, did a full wipe (/data, /system, /sdcard, caches), rebooted then restored from the Nandroid backup?
I'm still pretty new to all this but I've done some reading and a wee bit of flashing & rooting on Nexus devices and the HP Touchpad. I also have an old TF101 that I'd really like to tinker with as well.
Thanks!

I don't know much about kernel but I do know that Nandroid backup backups everything exactly where the phone is.
That means if you do factory reset and restore Nandroid backup it will restore everything from the day you made the Nandroid backup.
I hope it clarifies everything.
Let me answer your questions.
1. When you do a nandroid backup, it backs up everything. Including the kernel.
2. If you nandroid backup, factory reset your device then restore your nandroid backup. Your device will return to the same state you had it previously. You will have all your content, files and settings. However if you do a backup, then factory reset and reboot, your device will be wiped of everything but it will boot up. As if the device was just turned in upon purchase. Also note, if you do a backup, then wipe your device (factory reset) you will not lose your backup.
Just note, if you ever flash a ROM, even if the developer states there is no issues. MAKE A BACKUP, sometimes things go wrong.
Happy flashing

Thanks for the quick replies!
I was a bit confused about 2) because I read somewhere that if you make a nandroid backup of a stock ROM, then install a custom ROM (non-Stock based ie CM, PA or OmniROM) you must flash the stock ROM again before you can restore the nandroid backup, or else restoring the nandroid backup will not work. Is this true?
Consider the following example, say I:
-flash TWRP on my device and root
-make nandroid of stock, rooted ROM
-wipe /data, /system, /sdcard and caches and reboot back into recovery
-ADB push a non-stock custom ROM .zip file and flash the custom ROM
-decide I want to return to stock, rooted ROM after a while
-Boot into TWRP, then wipe /data, /system, /sdcard and caches and reboot back into recovery
-ADB push my original stock, rooted nandroid backup to /sdcard while in reocvery
-restore nandroid backup
What would be the outcome of the above example? I'm very curious...but I'd like some advice before attempting something like this myself as I'm still kinda new to all this
BTW I'm now comfortable flashing back to stock using fastboot and the google facotry image to restore a Nexus device so I now know how to do this in case things go south. I'm just curious if this would work on a device where returning to a full stock state isn't so easy.
No you don't need to install anything to get back to the previous state. So if you had a stock rooted ROM, then backed it up. But you decided to flash, let's say. Cyanogenmod but you wished to return back to stock, you don't need to flash stock ROM, all you have to do is just wipe data and restore your backup.
And for the example.
The outcome would be, you would be resulted with a stock, rooted rom.
