[Q] Restoring a Nandroid Backup from a previous Android version - ONE Q&A, Help & Troubleshooting

Hey, so I've decided to go back to Kitkat/11S as I'm not liking 12S/Lollipop. I made a Nandroid backup when I first got the phone with 44S using TWRP. Can someone tell me how I'd go about restoring this so I can get back to 44S? Is it also compatible as I'm worried that using a nandroid backup from a previous OS version could be risky?
Thanks.

There's no problem with reverting to an older Android version via a nandroid backup. Just make sure you perform a full wipe. You also need to flash KitKat firmware and KitKat modem first.

[Q] (Clockwork Mod) What is Nandroid Backup and How Does it Work?

This is a noob question, but I have a bit of experience under my belt just so you don't have to worry too much about using "confusing" terminology.
I have rooted/ROMed many devices in the past and have heard guides talking about doing a Nandroid backup. My question is how exactly does it work? Say for example: I am on the stock ROM (rooted of course) and I do a Nandroid backup while on stock. If go to say Cyanogen and I don't like it can I just restore from my nandroid backup like I would flash any other ROM to go back to stock. And if that will get me back to stock does it also preserve all of the user data that was in that ROM when it was backed up?
Any other information about about nandroid backups would be appreciated. Thanks in advance!
From my understanding, the backup backs up all the stuff on your phone EXCEPT for what's on the SD card.
The idea is that you do a back up. Then install a new rom that you want to try out. BUt you don't like it, so you just restore the backup and woolah! your old phone is back along with all your settings, data, etc.
I'm not sure why it's called a nandroid backup, but from what I gather, you can do it with clockworkmod, just boot into recovery. And use the backup and restore option.
That was my understanding as well. I just wasn't sure on the situation with the user data (or the backup in general really). So all it takes is a nandrid backup to revert back to (rooted) stock?
A Android backup takes all the files on your device and saves them as a data.img,system.I mg,cache.I mg,user data,and recovery.img. It is also restorable through fastboot. It can also get you out of a tough spot. Say you are messing with a new theme and it causes your device not to boot up or causes unwanted problems. You can restore a backup to a time when your device was working correctly.

this is true unless you do a nandroid+android_secure backup. this also backs up your external app data

Yes you're correct. You can restore but just remember some app might have ext data in sdcard. If you don't delete it, when you restore you'll get the same as before

So if you want to restore say just your data can you just delete the images you do not wish to restore from the backup folder and it will just keep the ones you have? Or won't it work at all if you start deleting images?

i wouldnt tamper with a nandroid backup, but if you have clockwordmod recovery, that is possible. clockwordmod recovery gives you the option to restore one of those images (but only one at a time).
does a nandroid backup include your kernel?

It does! It's a compelete "snapshot" of your phone with all apps/settings etc.
Does it also backup the stuff which has been stored on the external ext2-Partition, which is mounted to enlarge the space for apps?
Same with restore of this nandroid-backup. Will it also place the backup again to the same space?
As I know there's a (symbolic) link put into /data which might get problems.

If you install another ROM with different kernel and then you want to go back to nandroid backup, does it work ?
Nandroid backups
I was wondering if the framework is saved as well. I recently updated to the ICS firmware and am wondering if I restore with a backup from the old GB firmware will that be restored as well or will it still stay on the ICS? From my understanding ICS firmware will run previous versions
will nandroid backup (made from cwm) un-brick your phone if say, you installed a custom rom via cwm and it bricked it?

im not sure, i think nandroid backup will unbrick your phone as long as you can boot to recovery. atleast when i installed a roms pach it didnt fully boot, got stuck at bootanimation, no loop, just froze, then i got it back with nandroid backup

What's the point of nandroid backups?

I recently bricked my D801 attempting to restore a CloudyG3 (kitkat) nandroid backup over a modified stock Lollipop ROM. I'm thinking it was because I didn't flash the appropriate KK baseband first. Is that so? Why do I need to do that? Does the nandroid backup not include the baseband? So if I had flashed the baseband first would the nandroid restore been uneventful?
If somebody could walk me through these scenarios, I would appreciate it. What I want to avoid is restoring KK stock, rooting, using KK autorec to install TWRP, updating TWRP with Blastagator's newest version, installing a new ROM, restoring apps and data from TIB, reconfiguring all system data. I want to be able to use nandroid backups to avoid all those extra steps.
Scenario 1 (as above): Going from any variation of LP stock back to CloudyG3 KK. What do I do?
Scenario 2: Going from Cloudy to AOSP-based ROM having made a nandroid backup of Cloudy. What do I do?
Scenario 3: Going from AOSP ROM back to Cloudy, hopefully using the Cloudy backup. What do I do?
I have a JDI panel btw so it's imperative I avoid white lines. I understand that using Blastagator's TWRP will help avoid that problem because it auto-switches. I also understand that many ROMs (such as Cloudy) also choose an appropriate kernel automatically. Do all/most AOSP ROMs install a kernel? If not what do I do? If so are most of them auto-switching?
I'm not hard bricking this phone again if I have to use Cloudy KK until I sell it. There are worse things. But I'd really like to be able to go back and forth using nandroid backups as I have with other devices.
Thanks,
Ron

How to restore a TWRP backup?

E6683 (dual)
Stock Malaysia ROM (MM 305)
Rooted with rooted stock kernel
TWRP is 3.0.2.0
I've had this setup for months working nicely.
I did a full TWRP backup, tried N, didn't like it (for now) and so did a restore from the backup. Following a restore, it is stuck in Recovery! As in, when I reboot System, it just bounces back to Recovery.
I could try putting stock MM back on and then restoring, but before I do, are there any quicker tricks to getting the TWRP backup working again?
TIA
m
You should have switched back to MM before restoring your backup.
There are no other way around you have to switch back to THE SAME VERSION OF MM you were using during the backup.
Don't try this in the future you could brick your phone

Interesting... thank you. I would estimate I've done a TWRP restore across all phones perhaps 500 times. At a guess, I'd estimate 80% between the same version, so maybe 100 between versions. On this particular phone, this may be the first time I've tried it - I forget, I do so many. So, I'm intrigued: why? Or to put it another way: do you know what it is that TWRP fails to back up successfully or indeed restore successfully that causes this problem in the first place?
EDIT: I restored the MM stock rom (re rooted) and restored the TWRP backup and it worked fine - i'm back on MM.

Query regarding Nandroid backup

Hello,
I'm currently running stock oos, rooted.
I need to know if I wish to flash a custom rom now and take a nandroid backup from twrp of the current rom , what all partitions do I take a backup of.
Also, if I wish to come back to oos, do I need to flash oos twice in recovery and then restore the backup taken earlier for oos, or just wipe data and restore backup without flashing oos twice.
Thanks in advance!
