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.

Hello all,
I have successfully installed CM7 on my Nexus One. However, I have the following problem with CWM: if I ask it to make a backup from within the recovery or from RomManager, CWM (3.0.0.5, latest version available apparently for Nexus One) makes the backup, but after restarting, I am stuck on the CM7 splashscreen: I see the blue Android on his skateboard and the arrow goes around in circles (left it going for 15 minutes just to be sure).
Also, on a sidenote, when I made the initial nandroid backup in CWM from my stock Froyo, after the backup was done I had to go in RomManager and "fix permissions", because all my resident apps kept crashing with "forced close" errors. No idea where that came from. Restoring that backup did the same thing as well. I did not investigate that issue any more though as I was on my way to a CM7 upgrade anyways.
So I now have a perfectly good install of CM7 running, but I am scared of doing a CWM backup. This is far from an ideal situation, and I would love to be able to resolve this
Thanks for any help
Anyone? I really am quite upset with this situation
Use this instead?

Thanks, I will try it... though I have to admit I am nervous at the idea of having to again reinstall everything. Crossing my fingers!

Uh oh? It is just a custom recovery, no need to reinstall everything. You only flash the recovery and do the backup you cannot now with the broken CWM. (For my phone, there are even flashable zip files so you can switch b/w CWM and AmonRA "on the fly" via flash zip from recovery, not sure there are some for N1, try to search. )
Actually, the current problem I have is that after performing a backup, my phone doesn't boot anymore. The only solution I have at that point is to re-flash a complete ROM (flashing the backup doesn't work either), thus losing everything.
In short: making a backup means I then have to format and said backup is unworkable...
Which is why I am nervous at the idea of trying to make such a backup.
On a sidenote, RomManager is indeed able to flash both CWM and RA recoveries for N1 directly, which is quite nice indeed.

I still do not understand why all this. Just flash a working recovery from fastboot (should press power and trackball IIRC on your phone). (And obviously do not use CWM to perform backups when it bricks your phone.)
On another note, flashing removery via ROM Manager resulted in bricked phones for many users, would avoid it personally.
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.
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
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.
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.
