Weird issue with NVFlash - T-Mobile LG G2x

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

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.

[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.

[Q] The phone does not start.

I am using CM9 ROM, I don't remember which one because I was flashing it a while ago. Something strange happended to it today. When i try to run my phone it gets stuck at CM9 animation. Tried wipes and fixes from recovery but it didn't work. I would do factory reset but i don't want to lose my apps. They are on my sd card mounted as internal with flashed script. I don't know will I lose them? Help me please.

I don't think that there is any other method so just do a full wipe
and leave in peace AND YA PRESS THANKS
HAPPY NEW YEAR
Make a backup of your current corrupt rom.
Flash same rom again without wiping anything.. see if that works.
If not..you have nandroid backup img.. take out whatever important data you need.
I made backup, flashed rom and phone runs but there is another problem. When I restore apps from my backup they don't work. When viewed from system settings they look like: com.sketchbook 0,00 B and gray icon with sd card. The same happened to superuser app so I don't even have su rights. Do you have any solution for this or I just have to start with new rom?
Use terminal.. type su..
If your root access is broken you have root it again. There are numerous softwares.. use your pc to retrieve your data from nandroid img. Using titanium to backup app from nandroid backup doesnt work.
I just reinstalled superuser app and it's working. Anyway I think I will just flash a new rom.

[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] 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.
