Nandroid Backups?

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.

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] Problems restoring backup/installing ROMs

Hi Folks, I hope this is posted in the right forum and sorry if I've missed seeing something similar already here.
I have a rooted Verizon GSIII on which I have been flashing custom ROMs and restoring nandroid backups without any problems for a while now (most recently I've been on Paranoid Android). Today I decided to try out Carbon ROM. I generated a nandroid backup using TWRP, then downloaded the ROM (the most recent nightly) and Gapps zip files using GooManager and flashed these after doing a factory reset. After rebooting the phone it seemed to start up OK... but it got as far as trying to find the network, which it unable to do. After selecting the skip option I then tried to sign in to my WiFi, but the keyboard didn't show up for me to type in the password. So I figured I'd cut my losses and just reboot into recovery and restore my PA backup. I was able to reboot into recovery and restore the backup but the PA backup pretty much did the same thing the carbon ROM did... just looped trying to find the network.
So... I'm not sure what went wrong or what to do next. Any suggestions???
I am able to boot the phone into recovery, but I'm afraid to start messing around too much without help as I'm no expert!
I do have the most recent nandroid backup and several earlier ones that did restore OK on my computer. Is there a way to flash any of these to the phone or to go back to stock?
Any help would be greatly appreciated.
Cheers.
Wipe catche dalvik factory reset then flash fresh batch of rom and gaaps if that works well getting tru start up then flash ur backup thats what i did.. If that dnt work then u gotta go tru odin back to stock

[Q] Upgrade 5.0.1 and setup OK. Nandroid Backup OK. Boot Loop on Nandroid Restore

Hi --
Nexus 5 on Sprint.
I'm running into a boot loop issue when trying to restore a Nandroid Backup built on a fresh N5 about an hour after a clean install.
Details are:
I just this week updated from Stock KK (4.4.4 I think) to Stock LP (5.0.1) -- I've been waiting because of needing/wanting XPosed framework....
After unrooting and returning to stock recovery on KK 4.4.4,
I did the LP OTA followed by a Full Erase after the OTA to start fresh. (Note: I have subsequently experienced the same exact problem after installing the LP using the flash-all.bat from the Nexus 5 image extracted to the SDK/platform-tools folder.)
After completing the login and google's restore process perfectly... All things LP appear to be working well and my phone is set up the way I want. So...
I then installed CWM recovery 6.0.4.5 using fastboot.
I then used the CWM recovery to root with SuperSU v2.40
I then used CWM recovery to make a Nandroid backup... (after completing a rooted power up and returning to the recovery)
Long story short (kind of), within the first several hours I messed something up (install of Nine email app AFTER the Nandroid didn't work and was leading to android.process.acore stopping issues. Nine has since told me that the app is not compatible with my company's MDM security solution Maas36). So , I wanted to return to the Nandroid point in time and just put my company exchange email into GMAIL - Acore issues continued after removing Nine.-- but were NOT happening at the time point where I created the backup. So I booted into CWM Recovery and selected to restore and picked the backup I had made of the fresh device.
Restore via CWM recovery proceeds fine and completes. However, it goes into the flying circles boot loop (I tried leaving it go for upwards of 2.5 hours at the longest time
I can easily recover from this with a flash-all.bat in fastboot
I have done this numerous times today and it is completely repeatable. Same thing happens each time.
I have definitely restored from Nandroid previously using this process on KK. But so far no Nandroid restore possible for me on LP. To be clear, the LP install works fine, but just can't be recovered from the Nandroid backup. I guess I'm OK with that, but I'd rather not fly without a backup safety net.
Hopefully that's enough detail for someone to comment. If I've missed any helpful details, let me know.
So, have I done anything wrong? The only thing I can think of at this second is possibly needing to unroot before attempting the restore? Is that it? I don't think I've done that before.
Thanks in advance for any help that anyone can provide.

One quick addition. I figured someone would suggest using TWRP instead of CWM, so I'm going through that process now. I'll update the post if I find different results. I'm also making my TWRP first backup pre-root just in case that matters...

TWRP backup disappeared??

I've been trying to weasel my way into a stable marshmallow rom, or even stock updated ota. So earlier today I did a backup with twrp before I tried to flash (clean wipe first of course) cm13. I tried to restore the backup, after it was successfully completed and the restoration process only took 47 seconds.. obviously something went wrong with it. So I took out the battery, rebooted it and tried to restore it again to find the backup was gone. Same directory though I also checked the external sd. I mean thats not even a big deal bc I have another backup, but does anyone know why a backup would just disappear?
Thanks and happy flashing!
