Is there a way to convert a nandroid backup into a flashable zip file? I would like to have the possibility of returning to my rooted rom if ever I decide in the mean time to go back to stock rom and don't like it.
The question has been asked a few times but has never, to my knowledge, received a clear answer.

A nandroid back up takes a snap shot of your entire OS. All of the /system files, all of the /data files. All the apps in their current state. I mean EVERYTHING is store in the nandroid back up. When you preform that there is a "backup/restore" option in the Clockwork ROM recovery image. You would just select "restore" then select the back up you want to store. I will advise you not to change the name of the file as the MD5SUMs will not match and it will not be able to load it. It's a flash-able .zip my nature. but it will verify it's own MD5SUM prior to flashing it.
which brings me to this point.
but to restore you nandroid you need to be a) rooted b)have clockwork installed.
Yup, you can do it, but you need a few things:
1) system.img and boot.img to flash
2) you'll also need a non-stock recovery, so if you return to stock, just go back to a rooted stock system, and keep the non-stock/cwm recovery so that you can apply the zip. This begs neidlinger's point above about just restoring your backup via recovery.
3) if you want to really cross your eyes and dot your tees, then you should also get the EBT partition from the stock firmware so that you can update the bootloader. Most people are fine using what ever old bootloader they had when they rooted, but I think it can cause bootloops with certain combinations.
So yes it can be done, but it's more an exercise in android-fu. You'll have to search around and take apart a few zips to figure it out.
what about this (just to see if I understand the approach): I make a cwm recovery of my present non-stock rom and I somehow manage to go back to a stock rom. If I miss my custom rom, I root , install cwm recovery and restore the backup stored on my external sd card...How is that?

That is correct
You are on a custom OS, you make a nandroid backup Via CRW (ClockWork Recovery) (it will store to the SDcard)
you go back to OE not rooted OS with stock recovery.
you don't like it, it's slow or ugly, what ever.
you re-root. Reinstall CWR
you wipe the device
select "backup/restore"
Then restore
and it will restore the Nandroid completely.
you boot the device to the exact point in which you left it.
I made a backup with the stock "android recovery 3e". Anyway to extract it? It's a ".backup" file and I can't open it whatever i try. It's not a nandroid backup, but with an "backup" extension. I've been searching for three days now and so far haven't found anything. There were some other threads with the same topic too but no solution was posted. Any help would be greatly appreciated, thanks.
How big is the file?

Can you use the same recovery to restore this nandroid file or is that not an option?
I am not finding anything on actually extracting it..

It's not a nandroid file. I can restore it but it's not much of a help cause I forgot my lock pattern with wifi and data off. Debugging was not enabled and it's a new phone didn't even root it yet. I thought i'll just backup everything, factory reset and then extract my data from the backup file.
Now back to the point, i know there doesn't seem to be any way to extract it. Never made a backup with the stock android recovery before. I just needed to recover some imp photographs. Xda was my last resort lol.

Is there any way at all to root it once you restore it? If it's a full system backup then it's a "nandroid" (which means a ROM backup whether stock or custom).
But yeah can't seem to find any way to extract it, only hope is to restore it and try to do something with the ROM.

Idk, aren't nandroid files .tar or .zip? I was thinking of doing that. But i had some doubts. Like will the custom recovery be able to restore this file? Because I'm pretty sure i've never seen a .backup file in cwm or twrp.

"nandroid" just means a ROM backup, doesn't matter which recovery or what the extension is.
I mean anything is worth a try at this point. I doubt any recovery will recognize it, but I am thinking use the recovery that made the file to restore it, THEN root that ROM if you can somehow. What phone do you have? Most older Samsung phones can be rooted in Odin regardless of the actual ROM state etc...

No I can't root it after restoring. I'm locked out and there's nothing I can do about it. It's HTC desire 816g.
Good evening, I saw some questions similar to this one in the forum, but none had my kind of doubt.
When a new ROM comes out for both S7 and S8, I install via ODIN using the CSC HOME option, so as not to lose the data.
The problem is in the installation of TWRP whenever I install the same by ODIN, when entering the app and trying to install example no-verity ja start I get the message that the DATA folder has been corrupted and can not be mounted.
This way it only works once again doing WIPE DATA, but then I lose my data and I have to start from scratch.
Is there a way this does not happen or will it always be like this when updating a ROM?
Thank you.

Have you tried backing up data with twrp before you wipe and copying it to your pc so you can do a full wipe then put the backup onto the phone and flash It? You can back up data folder only

Good afternoon,
Thanks for the reply.
So from what I mentioned above, I do a full backup as I normally do, and I also do a separate from the DATA folder.
Then I install the ROM and TWRP, will it corrupt the DATA folder so I restore only it? Would it be this?
If so, will it work out, in relation to being a ROM different from the other?

The main rom info needed is contained in the system folder. The data folder is application data and whatnot. Reboot into twrp and use the backup option, then copy to pc. Do a full wipe of all, pit backup of data folder and new rom on internal or sd. Go into terp and flash the rom and data folder. Do not flaah system or it will overwrite the new rom. u will restore everything even if you don't have the APK installed in your system. It will return the data, you may need to reinstall the APK. Gmail for example will return will email addresses and messages, contacts and texts will come back to what they were at backup. You should back up modem and efs and boot as well and keep them safe. What I do is I get my phone set up fully, all apps I need and any games and data and then back it up again so any issues and I restore it to a fully functional state and don't need to install tons of things

Good afternoon,
I'm sorry for the text I'm using Google Translate.
I believe that I did not understand correctly, because the error happens in the following way, I install a ROM, reinstall the TWRP, yes yes it corrupts the folder DATA!
If I understood mistake, I apologize.

Is it a custom Rom or a stock rom? Also you can backup via ADB

The ROM I use is provided by Samsung, with no modifications, when I install it I use the CSC option the HOME file, in order not to lose the data, and of course, I do not lose anything I only update the ROM.
The problem is that I need to reinstall TWRP after installing ROM, and when I access TWRP it has corrupted the DATA folder.

You can extract the samsung md5 and repack it as a zip with superrs kitchen and then flash it from twrp. Just remove the recovery.img from the extracted files before zipping it up. Then you can simply flash twrp. Then the rom and not have to worry about the fact that you are stuck in a loop of being locked out because you don't need odin for the rom and it won't overwrite your recovery. If that's too much work try using a custom Rom from xda

Thank you very much for your patience. But I'm not clear, or you do not understand.
The problem is not in the ROM, but in the TWRP installation. If I install the ROM with the option CSC HOME I do not lose anything, everything is working correctly.
When I install TWRP it corrupts the DATA folder. The problem is there!

I was saying to use a zip rom because then you can reflash the rom without reflashing twrp. So you flash twrp, it says data error and then you flash rom from zip, which reinstall system and data but will not copy stock recovery over twrp. So you will not have to reinstall it and be stuck. Or try a different version of twrp might also help. Stock firmware overwrites recovery and the rom. You need to modify it to remove recovery from the firmware, or use a custom Rom to stop it from erasing twrp

I think I understood, more or less, since I translate for Google.
But assuming I want to use normal ROM, you have to back up the DATA folder before installing the ROM and after installing the new ROM and TWRP, restore only the DATA?
Thank you again.
Yes a new rom will overwrite data, you need a backup before. You should be able to connect your phone to a linux operating system and use adb to connect and back it up, if twrp will not let you take a back up.

In my case I can back up the DATA folder by TWRP. Is there doubt, if I back up the DATA folder in one version of Android and then restore in another version, will it be compatible?

Yes it will be, marshmallow and nougat are completely compatible from the boot loader up. You can also turn your stock samsung md5 into a zip file so you do not need odin to install it. You will be able to flash it from twrp

Can you not read the website?
I know what you mean. Twrp can't access the data folder because it's encrypted. But you do have to format it to gain proper access. You have to copy the files out or back them up

I believe that because I am a new user I can not exclude publications, I already tested in CHROME and IE. In the same way I can not give THANK YOU.
Throughout my phone's lifetime, I've made a lot of backups, most of which have ended up saved on my hard drive. I recently wanted to go back to stock from a custom rom, so I copied one of the emui backups over and restored to it. Everything seemed to go smoothly, no error messages, but attempting to boot only got stuck on the blue honor boot animation. Tried several other backups, some rooted and heavily customized, some fresh unmodded installs, but all of them did the same thing. Meanwhile, all my custom rom backups work just fine. What gives?
I tried it too and it doesn't work. I think its because to install a custom ROM we format the data using twrp which also removes the encryption of some sorts, when we restore the backup that encryption is lost so it stays stuck at the blue Honor logo. That's my two sense on this. I don't know the real details.

That does make more sense than anything I've thought of so far. So to restore from one of these backups, would I just have to reinstall emui from scratch first to get that encryption back? Is there another way to restore them without first having emui? Or are they just useless now?

I haven't been able to find a solution to this. What I do is use firmware finder to download the firmware+region zip and then install them together in any order via twrp. By this process you lose the data and twrp too as it is replaces by stock recovery. Before booting you must try to get into the stock recover and hit factory reset. You'll get EMUI back but no matter what you do you won't get your data back. Twrp backup is helpless I think because I've tried all sorts of things to get my data back.

I've tried flashing emui firmware through twrp before and the region zip always works, but I've never gotten it to load the update.zip (using adb sideload for everything). But I'll try a few different things and see if I can get that to work. Getting back to emui is my primary focus since most of my data is backed up somewhere else, but if I find a way to successfully restore data from backups I'll let you know.

What I'm telling is probably the easiest way let me break it down for you again.
1. Download firmware+region zip file from firmware finder.
2. Go to twrp, clear everything (format data).
3. Install the two downloaded zip I usually flash firmware and then the region zip.
4. After installation is over don't reboot go back to twrp home screen and reboot to recovery, which will be stock.
5. Format data using stock recover and then clear cache.
6. Restart and everything should work.
And if you find a way to get the twrp backups do post here.
