Few question
What is the difference between flashing from zip / restoring a nand backup / using kdz.
I have gone through all the posts and have taken a Nand backup after flashing the custom recovery. However this part am still confused about.
I know I need to use the kdz if I need to change the firmware ( 10b to 10c) and also there are cases of people bricking their device by using the kdz updater.
I know that I can upgrade to a different ROM by flashing the zip provided as part of the custom ROMs, however can I do a Nand restore of my original backup ? Would it matter if the version is different eg 10b of my backup and probably a 10e of the custom ROM ?
If the Nand backup restore / zip is much more stable then why are people still using the kdz to change the version.
Any answers would be really appreciated.
I have a question too: How do you restore nandroid backup from ADB ?

Flashing from ZIP is done in custom recovery, usually done for a fresh install of new ROMs.
Restoring a nand backup...I'm not sure if this is "nand" back up...but in custom recovery menu, you can create a backup image of your current phone/rom. I guess it's kind of like a restore point where u can go back to if **** hits the fan.
KDZ Updater, I believe is a tool where you can flash/install "official" roms. At least from what I know of LG Optimus One, official ROM packages are in .kdz package. Where as for example, for HTC, official ROM packages are know as "RUU" installers.
I think if you stick to your carrier's official KDZ ROM packages, there are minimal chance of bricking your phone. I was lucky to install one of Australian KDZ on my Telus Optimus One and got away with it.
You can do a (nand) restore of your original back up. To do this, root your phone, flash the Custom Recovery (follow one of the stickied posts in this thread), and create a backup. When you restore, your ROM version will be whatever the backup ROM version is. So if you backed up v10b, and you update to v10e, and then you restore your back up, you'll revert to v10b.
As I mentioned above, I think KDZ are for flashing official ROMs. It's the tool that LG uses I believe, so probably that's why all their official ROMs are in KDZ. People are using KDZ to downgrade/switch ROM versions because some of ROM versions, such as v10e, can't be rooted using conventional tools.
So which is the command for nandroid restore in ADB ? Thank you.
Nand restore/backup is not ADB tool. You have to boot into recovery mode (if you have custom recovery, just turn off phone, press volume down+home and keep preset power on button. Hold volume spek+home till custom recovery menu didn't appeare.)
Warning: If you will not have installed custom recovery properly, you will do only hard reset!!

nanddroid backup (i think can be restored using nandwrite linux utility try sudo apt-get install mtd-utils) ..NAndroid is more Like(HArd Drive Cloning) whereas FLashINg USING KDZ is like upgrading Your PC's BIOS system...U know what i mean ??? U screw up FlASHING phone is dead until fixed by the manufacturer..HOwever for same model i cud use my friends nandroid backup on my phone..Its like CLONING a OS
If using NANDroid restore from ADB you should navigate to the folder of your backup and run "nandroid-mobile.sh restore". The rest is explained above.
And by the way, sarfaraz1989, the only way to brick your Optimus One is to delete all the "/" directory, as even if you mess up the kernel, you can enter "Emergency Mode" and restore from a KDZ file. Second - NANDroid creates a binary image of the "system", "data", "boot", "cache", and optionally ".android-secure" directories. Third - flashing ROM updates is not the same as flashing a KDZ file - KDZ is LG's restoration archive containing the original ROM, recovery, kernel, etc... and most ROM updates contain updates to one or several system directories.
@Ianis DOesn't FLASHING rewrite the EEPROM chip on the phone??? Doesn't it repartition the ROm into boot,system,cache etc...??? And does't cloning (Dd) create "binary images" What imeant by FLASHING was using the KDZ file only... u missunderstood the post or mayb i didnt put it correctly
it's weird... i'm successfully backup (indeed four kind of nand back up available @ recovery) my source for backup was void#echo + latest fixed multitouch kernel, it just work beautiful before.
Some issue that require flash back to origin 2.2 rom using KDZ, then root + install recovery but any kind of restore still return LG LOGO and hang. (all 4 kind of backup same result)... already clear /davik-cache + /cache even try to clear /data and /ext as well but still the LG logo.
P/S: i'm using Recovery version 1.2. and my card already partition as 0 for swap + 512MB for ext4 that working beautiful @ void rom before.
Any solution? I can redo all the step by step for reaching the same VOID rom but without restore fully function like that... it waste lot of time for "boring HOME WORK"
Many Thanks and Best Regards
I think you have to flash the raw rom again.
Hello there guys.
I've done a full backup with clockwork but if i try to restore it i get a error message about the boot image...i can't restore it. now i was able to restore system..data..and so on via advanced restore...i get no boot animation but the system is up an running. i can't get the wifi to work...what can i do now?
I used a clockwork 4.0.1.4 with root enabled..i flashed it whit Odin.
Thanks guys
forgot to mention I own a Galaxy S 2
Flash a clean stock rom as your backup is corrupt.

Same issue
I took a full backup with CWM (4.0.0.2) to test a Kitchen ROM. After getting it to work I wanted to switch back to my standard ROM (CF-Root KE7), but it failed with the boot image ("error flashing boot image").
If the backup was corrupt I would expect the MD5 to fail, but it didn't. Like the OP I was able to restore all the other items one by one, which now gives me a Frankenstein ROM: KE7 with the Kitchen-selected Kernel (Ninphetamine) and baseband (KH1).
I'll flash a new stock ROM with CF-Root again, but I am doubting CWM now.
So I probably should of asked this before flashing but anyways, I flashed CWM to my tablet and I am about to flash aokp to it but I was wondering if I was going to go to back to complete stock again does it matter what stock 3.2 recovery I use to get official updates? I did make a nandroid backup so I am not to worried about getting a stock OS but its just the stock recovery that bothers me.
For the record I have a Canadian WIFI 16 gig tablet.
Official updates...? Odin is the only official update you need! :] Just so you know, you can't completely revert to stock unless it's for that specific firmware, only way to do that is by a clean flash to avoid all the un-necessary bricks and such.
Nandroid backup does not exist on stock and last I checked the recovery and CWM do the same job of "Applying update.zip" so it shouldn't matter, it's the firmware's regional value that matters, not the recovery.
So if I were to do a restore of my nandroid backup (from CWM) then that means that I would be able to get the notice that I would be able to update to the latest official firmware from Samsung no problem?
As long as you don't use Cus ROM's then yes.
I need to restore the og splash screen to return my phone to at&t
Can anyone help please
The best way to restore original state is to flash stock ROM using Odin. First and last problem in this method is to find proper ROM for your phone.
I found one in this forum but did not fix my issue
I mean it should be STOCK ROM flashable by Odin, not custom ROM. If you found stock rom and flashing it did not fix your problem it means this ROM was not RIGHT for your phone OR problem is with hardware...
Remember ALWAYS clean cache and dalvik before flashing new ROM.
Hi so after updating from the stock zv6 to lollipop update my phone won't install a custom ROM. Every time I try to turn it on it goes straight to TWRP and went I install a ROM or try to load a backup as soon as I hit reboot it goes back to the TWRP page. Amy ideas?
You must flash back, using Flashtool, to zv4, then reroot, then flash newest TWRP. OTA software not included, because they flash every partition of the phone, including the boot loader. Stock roms like zv6 and zv8(lollipop)or AOSP, must be flashed from xda from here on out, because they've been modified to work correctly on zv4 boot loader. TWRP and root access only work correctly with zv4 boot loader.

It sounds like there is no OS installed or it is stuck a reboot-loop. Try pulling the battery out for 10 seconds and if it still goes into twrp you know that it isn't a reboot-loop. When you go to restore a rom and it has the bar that shows the amount of storage does it say "0 MB"? If it does it means that twrp can't mount the storage on the phone thus causing it to not install/reboot. Have you tried side loading a rom via adb? Are you trying to install a rom off of a sdcard? I have seen many issues in the past sdcard related.
If you can please answer the following:
1) What is the message you are getting from twrp (if there is any)?
2) Have you installed a custom kernel and if so witch one?
3) What twrp are you running (the bumped one from xda or from the official twrp site) and what version is it?
4) Have you tried adb and pulling the battery?
If you answer these questions they should be able to tell us all that we need to know in order to help you out.
