I got a replacement GS3 from Verizon because my current one had a charge port issue. I rooted and am using CWM 6.0.2.3 and get "error while restoring /system" when I try tp restore the nandroid of my old phone to the new one. How do I fix this?
Did you change the name of the nandroid at all? It's also possible that the backup you made contained individual phone information specific to your old phone...I seem to remember a thread before that mentioned it wasn't a good idea to move a nandroid to a new Samsung phone.

there are a couple of apps where you can just extract the nandroid apps on the play store, but if you want the full restore, the file is probably corrupted.

Yeah I used to use titanium backup but my phone is very customized, CM10, diff kernel, and a very highly customized home screen so I'd rather restore the nandroid if there is some kind of workaround. I also want all my data, texts, etc. without using titanium backup. When I used ti backup in the past, I had a bunch of different issues restoring apps and data, force closes, etc.

I followed the directions in the last post of that thread.. I made a backup of the new phone, moved the old nandroid from old phone to the twrp back up folder in my new phone. I copied the new backup name and deleted the new backup. i pasted the name into the old back up, I tried to restore and i get an error "no partitions selected for restore. Is it because Im using twrp and I made the old backup with CWM?
Someone help!

That could be it. They back up with different formats. Cwm uses the blob folder twrp does not.

Hey all
I wanna update to 4.4.3 but I want to wipe everything, then restore some things I want cause the battery life on my phone is pretty bad even using greenify for just about everything I can...
I'm running stock rom with Xposed and Franco kernel, I have Titanium backup pro and a backup I took with my CWM recovery.
How do I go about this? I want everything deleted with the option to restore my apps and their data ,What'sApp conversations, PvZ level progress, and my Xposed settings are the important ones.
Does the Titanium backup I have save these things? Do I need to copy tyhat backup off the phone before doing anything cause it will be deleted in the process?
Pretty sure this has been answered in one of the million duplicate threads posted yesterday. Did you read them / use search?
Sent from my Nexus 5 using Tapatalk
Yes but most asked how to upgrade without wiping, I want to wipe everything then restore some stuff. This is my first Android upgrade so I'm a bit :?
Like restoring Xposed settings with all my modules and stuff, I have no idea how to do that.
Also, do I need to revert to the stock kernel before doing all of this? I'm a bit scared of all this.
Titanium backup is your best bet for backup / restore. Don't wipe your sdcard.

Doesn't "flash-all" flash userdata which wipes /sdcard?
I wouldn't ever recommend using those batch files. You only needed to:
Code:
fastboot flash system system.img
fastboot flash boot boot.img

It does which is exactly what I wanted. I wanted a complete overhaul that deletes everything, like a new phone.
I saved my TitaniumBackup folder from /sdcard to my PC and now I restored it, this is pretty much what I wanted and TB really backs up almost everything. I'm happy so far

The only benefit was that this is my first Android phone and I tried a lot of stuff before settling with what I like. That left a whole lot of mess on the phone and even in /sdcard there was a lot of crap that I have no idea what it was and weather or not it's necessary. Now I can take another look and if anything is back I know it's needed.
Hello Guys,
Since I totally bricked my old Nexus 5 16GB(KTU84P) I am going to get a new one. But I am thinking of getting the 32GB version this time.
Now before it got bricked I made a full nandroid back-up with the help of the Nexus Root Toolkit and TWRP.
Now here are a few (stupid) questions:
~Is it possible to restore a nandroid backup from one phone to another and even in this case a "different" version of the phone?
(I've skipped over this thread real fast http://forum.xda-developers.com/showthread.php?t=728266 which says it is possible for phones of the same model)
~If it is possible how should it be done?
~And well if the first question isn't possible, is there a way to read out out the created back-up files which TWRP created and manually restore them(preferable the data partition)
I hope you guys can help me out
Kind regards
Yes, you can do it. Just make sure you're not restoring the efs partition or you'll have another brick on your hands.

When you run into issues, as many do after nandroid restoring from one device to another... Wiping and Flashing stock with fastboot is the Fix.
Thought I'd cover that up front. ?

Hey guys sorry I didn't answer immediately, but after I saw the posts I immediately ordered a new Nexus 5 (32GB this time). I got it delivered today and like you said I've done the unlocking, custom recovery and rooting manually this time instead of using a toolkit. Which was to be honest way easier than I thought but also way faster than using a toolkit.
But now I've kinda run into a other 'problem'
When I restore my previous made backup (the one from the bricked phone) I first of all only get the options to restore the 'system' partition and the 'data' partition (which is totally fine cause those are the only ones I actually need).
But when I restore the system partition a lot of apps crash on default(It is basically bricked then), and even when I just restore the data partition the same thing happens. (To be completely fair this problem might come from the fact that I used the MD5 verification option when I made the backup but I can't really remember that. but some of my backup files end with the .MD5 extension) Saying this I also used the restore option with check MD5 verification, but needless to say I get the message that they verifications don't match.
So here are a few questions again.
~Like I said before I only really care about the 'data' partition, Is there an option that I still can use TWRP to restore it properly?
~If the above is not possible is there a manual way to read out the made backup file using a program like 'Ext2Explore'(This crashes though when I open the file)
Or did I just completely screw up by checking the MD5 verification?
Once again kind regards
p.s. If the problem isn't clear tell me and and I'll try to explain it in a different way
You missed quote from post #4. ?
I believe that with a new device.... It should be a clean start. And I read post after post in different device sections of issues from restoring from other devices.
And so I never recommend it. It can, possibly, bring lots of issues.
But to each their own.
Good luck. ?

Ohh right, sorry I completely read over your post my bad. But then again If I have to wipe the device wouldn't that totally remove the point of restoring the data partition ? or is the wipe command just for the system partition?

What I'm getting at, is don't restore the data partition. You can try, but I often read of lots of issues doing it.
Yes, I implied wipe the device clean. Flash stock. Start fresh.
Now if you had a titanium backup of user apps on your pc... I'd say you'd have a much easier time restoring that to the new phone.
Just my 2 cents of course.

I made a clean start yes. Unfortunately I don't have a titanium backup and I get that storing the data partition to a other device isn't a good idea. But well I never had the intention of making a back up and restoring it to another device but unfortunately my other phone got completely bricked. And yes in hindsight I should have made backups in multiple ways.
But like I said I don't really care about the system(including the apps and app settings) it is literally all about the actual data (pictures and stuff), that is also the reason why I asked if there is a way to manually read/open the back-up files.

Did you make an adb backup in the tool kit? That would have your pics. But a flashable nandroid you flash in recovery would not.

Would Nandroid Manager be what you're looking for? EDIT: as above, it won't find and restore any of your pictures/music, as a nandroid backup does not include any of these. There is a chance you find and restore your apps and settings if you so wish. I've used that app before.
Incidentally, I successfully transferred all of my data and ROM from one Nexus 5 to another (had to RMA)
The process I used is:
- Unlock bootloader, install custom recovery on new N5
- Nandroid backup on old N5
- Copy whole /sdcard partition from old to new N5. Basically, all files and folders on the 'root' of the drive when connected to PC. This included all photos, music and the nandroid backup itself.
- Restore nandroid backup on new N5 (only /system, /data and boot.img / kernel), as if you were restoring any nandroid backup really. Though do not restore efs partition as advised above (it wasn't backed up, but worth mentioning again anyway).
Took a while, but the ROM and settings were carried over successfully.

Nope, I did not. And the ignorant person that I am just assumed that the nandroid backup would back up everything since the toolkit says "Make full Backups"
So well I guess I just have to accept the fact that I lost those things

I am assuming that you used a tool like Android File Transfer.
So what I'm trying to do is the same thing, backup my entire old N5 32GB as I had also requested an RMA of the device. Is it accurate in stating that you want me to copy every folder that shows up on the AFT window (Note: I am using a MAC) and copy that onto a folder on my computer. Then copy over everything on the new device (bootloader unlocked, rooted, same TWRP version installed) and restore via the Nandroid backup from my old phone (which was also transferred as indicated above).

I didn't use AFT, just plugged straight into PC, sorry no experience with Mac
Basically both phones were connected, and I copied the whole "/sdcard" straight from one phone to another, without making an initial copy to the PC

Hey guys, I'm rather new to the world of customising Android devices. I just have SO MANY QUESTIONS right now. And I'm sure I'm not the only one, which is why I created this thread to help myself and other people.
Basically, I'll be asking a bunch of questions related to the topic, and this can help other people who are new to all this too.
So, I've got a rooted device. It's on lollipop 5.0, has an unlocked bootloader, TWRP recovery, and Xposed framework.
A few questions to start off with:
1) Can I flash multiple .zip/.img files one after another? Or do I need to always wipe my phone's cache after each flash?
2) Say I wanna update TWRP recovery. Do I have do something before flashing it? CAN I flash a newer version over the previous one?
3) Same question as 2) but for Xposed framework instead.
4) I have Xposed framework installed with some modules running on my phone. Should I disable these modules before updating my Xposed?
5) The latest version of Xposed is v86 as given here: http://forum.xda-developers.com/showthread.php?t=3034811
Can v86 work for lollipop?
6) Similarly, can one download any TWRP version and flash it for their device? Or do each build have a different, specific version of TWRP?
7) Are the latest recovery mods and Xposed frameworks always guaranteed to be stable? Or is it safer to stay on the older ones? Which ones would you recommend?
8) Now, the custom ROMS. What are the necessary things to do before flashing one of these?
9) After flashing a custom ROM, can you flash another on top of it? Or do you have to restore back to your original stock ROM?
10) Does flashing and switching between custom ROMs cause any damage to the phone? Or is there any such potential?
11) Since backing up is a must, I'll ask some about that too. Which would you suggest to be the best backing up method?
12) Does creating a NANDroid backup or a backup from within custom recovery(TWRP in my case) equal to creating a backup of stock ROM?
13) Do I need to copy that backup into PC(to restore later), or will it be safe in my phone's memory after flashing a custom ROM?
I guess that's about it for now. Everyone, please answer if you have done these before. And of course, add your own questions too. This can save a lot of time for a lot of people. I could add more questions in if people request it.
**Answer mentioning the question number for simplicity of searching.

1) Can I flash multiple .zip/.img files one after another? Or do I need to always wipe my phone's cache after each flash?
Click to expand...

You can, but it is more recommended to wipe cache and dalvik cache with each flash.
2) Say I wanna update TWRP recovery. Do I have do something before flashing it? CAN I flash a newer version over the previous one?
Click to expand...
Click to collapse
You'll have to wipe dalvik cache and cache and just flash it normally. It might be stuck at 90% but a force reboot fixes it. It is because you are already in recovery. If it is stuck, leave it for 15 mins and come back. This is just to ensure that it really is stuck.
3) Same question as 2) but for Xposed framework instead.

Yep, works, except you wont be stuck.
4) I have Xposed framework installed with some modules running on my phone. Should I disable these modules before updating my Xposed?

Yup, just flash it via recovery
6) Similarly, can one download any TWRP version and flash it for their device? Or do each build have a different, specific version of TWRP?
Click to expand...
Click to collapse
Each build is different for each device, so for example, I can't flash a TWRP for s7 edge on my s4.
7) Are the latest recovery mods and Xposed frameworks always guaranteed to be stable? Or is it safer to stay on the older ones? Which ones would you recommend?
Click to expand...
Click to collapse
In example, xposed and supersu framework and binary lets you choose if you want a stable file or a test one for developers. TWRP and other stuff have (what I know) different versions and as stated, these versions behave different on different device. During testing with my S4, I found that TWRP 2.8.7.0 is the most stable build for my device.
8) Now, the custom ROMS. What are the necessary things to do before flashing one of these?
Click to expand...
Click to collapse
Make a nandroid backup of your whole device and back it up on you computer. Then wipe everything except your external sdcard and either store it on an sdcard or "adb sideload" it.
9) After flashing a custom ROM, can you flash another on top of it? Or do you have to restore back to your original stock ROM?
Click to expand...
Click to collapse
Not on top of it, you'll have to do as the answer to question 8, make a backup, wipe everything and then flash. No need to go back to stock ROM and then flash it
10) Does flashing and switching between custom ROMs cause any damage to the phone? Or is there any such potential?
Click to expand...
Click to collapse
There is always the risk of bricking but as far as software, it is always revertable. As long as you have a backup of course.
11) Since backing up is a must, I'll ask some about that too. Which would you suggest to be the best backing up method?
Click to expand...
Click to collapse
Nandroid backup is the best one.
12) Does creating a NANDroid backup or a backup from within custom recovery(TWRP in my case) equal to creating a backup of stock ROM?
Click to expand...
Click to collapse
It creates a backup of your current state, lets say, you are in Cyanogenmod 13, making a Nandroid backup will backup everything on cyanogenmod so that if you flash another ROM and still want to go back, you'll have everything restored, including app data and apps.
13) Do I need to copy that backup into PC(to restore later), or will it be safe in my phone's memory after flashing a custom ROM?
Click to expand...
Click to collapse
It will take up a lot of space on your device (since it is a backup of your whole device) so it is recommended to copy it to your computer and remove it from the phone. But, as always, make sure you copy the whole "BACKUPS" folder because the folder inside that folder has your device ID and it is required by TWRP to have the folder the exact ID of your phone to prevent anything bad from happening (bricks).
Hope, I answered all the questions as you wanted and if you have a new question, post it here and I'll reply as soon as possible
Hey, thanks a lot for answering. It helps a lot.
A few other questions I have:
14) So if I were to get CM13, and then create a backup of it, and then get another rom, say ASOP, create a backup of that too, and then switch to yet another rom, say Resurrection Remix, create a backup of that too.
Now, is it possible for me to be able to SWITCH between multiple roms, with ALL my data saved individually on each rom perfectly the way I wanted?(of course, wipe cache and data before restoring the backup)
If so, then I could just keep Nandroids of my favorite roms, can keep switching between them, never having to flash and start from scratch ever again!

15) Since I don't have otg cable, nor an sd card reader, I'm gonna have to keep the nandroid on my sd. Which means a lot of space is needed.
Can this workaround be possible:
- I use TWRP to backup only system and boot data. I save this on sd card.
- I use Titanium backup to save only user app and data. I save this on PC.
So now, when my device crashes while flashing something, I can restore backup from TWRP(do I clear cache and data before this as well?), and once my system rom is back, I can copy titanium backup via USB and restore it.

16) Suppose I flashed CM13, and it's really buggy. Can I switch back to the previous rom whose nandroid I had just by restoring it? Is it really that simple?

You do not have to have an sdcard reader to view your sdcard on your PC. You know how when you make a backup it is stored in /sdcard/TWRP/BACKUPS/CERIALNM/nameofbackup? Well, connect your phone to your pc and move the "backups" folder, then, when you need to restore it, add it to the twrp folder and restore it.

15) Since I don't have otg cable, nor an sd card reader, I'm gonna have to keep the nandroid on my sd. Which means a lot of space is needed.
Can this workaround be possible:
- I use TWRP to backup only system and boot data. I save this on sd card.
- I use Titanium backup to save only user app and data. I save this on PC.
So now, when my device crashes while flashing something, I can restore backup from TWRP(do I clear cache and data before this as well?), and once my system rom is back, I can copy titanium backup via USB and restore it.

Also, on the titanium backup part, not a bad idea... You can then copy the data and system or boot to your pc and bam.

What I meant was: Let's say I bricked my phone. Now, according to you, I place backup on pc. Okay. But now, how do I place this backup onto the sd on my phone when my pc can't even detect the phone(cuz it's dead yo). Doesn't this impose on me to keep the backup in sd(as I don't have reader or otg).
About the titanium, so you're saying I can do that? Backup only user apps+data and restore after restoring only system+boot.
Another question:
16) Can the backup of user apps+data made on, say, 'X' rom, be restored on 'Y' rom via titanium, on condition they are same Android version(suppose 5.0), without ANY chance of incompatibility. More importantly, can it have any chances of leading to a brick/bootloop.
* I read somewhere that if you backed up system apps of 'X' rom, then changed to 'Y' rom, and restored the system apps of 'X' rom onto 'Y' rom, it bricks the phone.(which is why I ask this question)
17) "Backing up 'system' in TWRP is completely different from backing up 'system' on titanium. This is because TWRP backs up entire system with system apps, while titanium only backs up the apps." This is true, right?

You adb sideload a functioning ROM and once you boot you copy the backup you can flash it via twrp. As for the second question, I have not tested it but it sounds possible.
16) You should not be in a bootloop if you backup like that, the fact that it is even the same android version is making it more likely to work and what I know, you can even switch the backup via phones. I don't use titanium because I always do nandroid backups.
17) Yup, that's true, twrp sees "system as the partition system while titanium sees it as the whole phones software, hence why it is called " system".
Thanks for asking these question and hopefully some day, you can teach others.

Hm... so whenever I brick my phone, I MUST adb sideload to a working rom first, and only then restore the backup I made? Even if I already have a backup saved onto the sd card of my bricked phone? Can I not restore that via TWRP instead? I ask this because if I were to adb sideload first, I'd lose root, unlocked bootloader, and yes, TWRP. So, I'd have to get ALL that done again, and only then restore my backup.
18) Does restoring a backup I made(when I had root access, unlocked BL, custom recovery, xposed) RETAIN all that? Meaning after I restore to that backup, I will still have all that.
Thanks for answering, I'm learning quite a bit. And yeah, I'll make sure to help others with this information too.

You won't lose TWRP or unlocked bootloader, but I will try today by making backup of "cache" and flash it via my sdcard as soon as possible.

Actually, when you adb sideload, you need to flash stock fastboot and recovery .img files(at least for my phone), and the bootloader does in fact get locked again, along with losing root. I know cuz I already have done adb sideloading before. So, doesn't that make flashing backup via sd card and TWRP without sideload the only thing I can do? I'm just trying to keep a backup without losing root, unlocked BL, TWRP, even if I gotta give up some space... Just wanna make sure it's safe to do it like that.

You wont lose anything during a complete nandroid backup, and, apparently, some devices loose stuff during adb sideload.

There's this thing you can do where you move your apps from internal storage to sd card COMPLETElY, thereby saving a lot of space on internal memory. It works because a 'link' is created between the app+data(now in sd) back to it's internal location counterpart(where it would have been otherwise). This way, the apps and system think your apps are in internal, but in fact are in sd(you can see that more internal is free by checking space used up via any file manager though).
In order to do this, a second partition on the sd card is to be made with an ext2/ext4 format, and use a linking app( like Apps2sd).

Yea I've used one of those, I first thought the app used the "MV" Unix command but yea you need a sec. Partition to do that on the sdcard, but you don't have to do that on your nandroid backup.

Hi XDA experts
I am newly registered in the forum, but experienced in modding (more or less). But I am (for now) strictly a user, not developer.
So far I got along very well, with my beloved Galaxy S4 jfltexx. I got from stock to rooted stock, from there to cm, instantly back to stock, used it for a long time and am just now on cm13 nightly, which is truly awesome!
It is so awesome that I would really like to help other people out, even if they have no idea about this. Meaning I wish to modify other peoples phones for them. However, when it comes to other peoples property I can't really fight my way through technical terms I don't understand anymore, hoping that the outcome will be as I wished. I pretty much know what most of all these technical terms mean, but I don't always understand how they are related to each other. I know, explaining this will take a while, but I would REALLY appreciate it if someone would take the time...
1) The bootloader, can it be replaced? What would be the purpose of that? UNLOCKING does not mean REPLACING, does it??
What do custom ROMs typically consist of? An entire working system? Parts of a working system? Sometimes this sometimes that?
I'm asking the question because I got the impression that some custom ROMs require the user to have a certain (usually stock) ROM in order to flash it. For example, if I had a Galaxy S6 edge running 5.1.1, could I upgrade to noble ROM Marshmallow?
I also have the feeling that the ROM or system or whatever is somewhat seperate from the kernel. What is this relation? Do custom ROMs not always come with a compatible kernel? Is there only one kernel compatible to the rest of the system, or is there a chance to run a system with a kernel not particularly designed for it? How to get a 'wrong' kernel?
Where to get stock ROMs and who provides them? If I wanted to upgrade from Lollipop to Marshmallow, but am rooted and don't get OTA updates, what do I do? Assuming that Nandroids are bound to a single device (e.g. MY phone) who can provide a stock ROM that runs on my device and how does he get it?
Can I run pure Android on any phone, or is it (always?) necessary to adjust it? I understand that my hardware buttons of the S4 would probably not work on pure Android, but the rest?
Is there ANY phone SOLD with open bootloader and root? A phone that actually wants its users to play with the system?
Thanks guys

Click to expand...

The bootloader can be replace, however, if you fail here, there is no comming back (you'll need a complete board replacement because the bootloader acts as a BIOS), the purpose of replacing it is various reasons, change of splash screen during boot etc. Some bootloaders are locked to only be able to flash certain ROMs (OEMs do this to not allow people to tinker with their devices) but it is nearly always un-lockable (except for some devices, I own an Acer tablet that has a locked bootloader that cant be un-locked) and no, unlocking it does not mean changing it.

Yea, sometimes this sometimes that, in example, ported marshamllow touchwiz ROMs rely on some files in the stock ROM so the "update" doesn't take up much space.

That is because of the bootloader (again lol), from my experience with the s4, before flashing cm13, I had to go to 5.1.1 because of the bootloader was changed during the OTA, so as stated before, it only allowed a certain type of ROMs to be flashed.
I also have the feeling that the ROM or system or whatever is somewhat seperate from the kernel. What is this relation? Do custom ROMs not always come with a compatible kernel? Is there only one kernel compatible to the rest of the system, or is there a chance to run a system with a kernel not particularly designed for it? How to get a 'wrong' kernel?
Click to expand...

The kernel tells the system what to do, some kernels are specified for battery optimization, so the kernel tells the cpu to slow down and save juice, while some other kernels offer the ability to overclock the device (mostly used on older devices to make it faster, but it drains more juice and can result into app crashing), the kernel, is not separated from the system, in fact, you can't even compile a ROM without a kernel. There is not only one kernel for lets say cm, you can flash another kernel, just make sure it is compatible with your android version. To get a wrong kernel, flash one that isn't for your device or android version.
Where to get stock ROMs and who provides them? If I wanted to upgrade from Lollipop to Marshmallow, but am rooted and don't get OTA updates, what do I do? Assuming that Nandroids are bound to a single device (e.g. MY phone) who can provide a stock ROM that runs on my device and how does he get it?

Your OEM provides them, samsung has a website called sammobile and uploads all the stock ROMs there. If you want to upgrade, just flash it via recovery or in your case, odin (for samsung phones). To give your backup to someone else, the other person must have the exact same phones, in example, you (jfltexx) can't give it to me (ks01lte), I must have jfltexx and then (assuming you did the backup on twrp) I'd have to change the serial number to my device.

There are a few devices like that, one plus was a company that wanted to do that, it came with root, unlocked bootloader and cyanogenmod running, they separated unfortunatly and evolved to using "oxygen os" and does nor provide a un-locked bootloader but provides a simple tool to root and unlock. I don't know any companies that have unlocket bootloaders because they don't want the average consumer to mess up their device and blame it on the OEM.

Yea, you know how your backup is located in /sdcard/TWRP/BACKUPS/SERIALNO? The device you want to flash it to should make a backup of the tiniest partition (usually cache, it's 5mb) and youll get acces to the serial number, then you just swap it and delete the tiniest partition.
So I have the OP6 for a while now. Everytime a new version released I download the new official zip file and then flash it with twrp. (follow this post - https://forum.xda-developers.com/showpost.php?p=76596833&postcount=3)
So I did it for 9.0.4, I first took nandroid backup, flash the new firmware, flash twrp, reboot to recovery, flash magisk. And then when I tried to reboot the system I got a message "Shutting down..." when the android system tried to load so I was stuck at bootlooping.
I thought that maybe something in the installation went wrong, so I might just get it restored. I did the restore using the latest twrp (v9.91) and now the system is completly corrupt, the phone no longer able to load anyhing (no oneplus loading screen with the rolling dot) and I when it boot to twrp it no longer can decrypt the filesystem (doesn't ask for my password).
I don't know I could I meesed this up, I did the same step every new upgrade. Apperiate any insight to my situasion.
What do you think caused this? Can I decrypt the files on my phone somehow and restore them?

Ok this is a giant pain in the backside but I have done this before and I know it works. Here is a step by step guide to restore.
1. https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665 go here and download the fastboot rom for the rom YOU HAD ON THE PHONE WHEN YOU MADE THE NANDROID BACKUP. Step by step on how to install it is there.
2. Install the rom and boot up the phone. Don't bother signing in to google or downloading apps or any of that. Just get through all the menus.
3. Install TWRP. Bluspark TWRP is recommended.
4. Install Magisk, but make sure IT IS THE SAME VERSION OF MAGISK AS WAS INSTALLED IN THE NANDROID BACKUP
5. Reboot to system and make sure the phone still works, then reboot to TWRP
6. Restore Nandroid backup.
I know this is a giant hassle, but it works every time. I haven't found a better way to restore a backup since this whole A/B partitioning started.
Thank you for making the time writing this, it is relief to hear that you figure this out. Will try this first in the morning.
I did a bad mistake running the flash-all.bat thinking it will only flash the partitions of the system.
Well it is all gone now...Dam if only I wait until the morning I might not made this mistake.

tabletalker7, can you please explain a little technical detail? If i follow your procedure, what is the difference from me just restoring boot, system and data from a Nandroid backup of a system that used to boot? What causes the restored system to no longer boot?
Because you seem to be suggesting a solution for the the problem I had. I normally do plenty of backups and play around with the system quite a lot, but Op6 burned me: I was unable to restore from a backup like I always did on other phones. I tried suggestions from other posters to no avail. So I set up a clean system from a fastboot rom and reinstalled everything from Titanium. I wonder, after I set pretty much identically, should I just risk and to once more try to restore from that Nandroid that was failing to restore (that only had system and data btw)? I'd greatly appreciate if you can enlighten.

I thought that maybe something in the installation went wrong, so I might just get it restored. I did the restore using the latest twrp (v9.91) and now the system is completly corrupt, the phone no longer able to load anyhing (no oneplus loading screen with the rolling dot) and I when it boot to twrp it no longer can decrypt the filesystem (doesn't ask for my password).
I don't know I could I meesed this up, I did the same step every new upgrade. Apperiate any insight to my situasion.
What do you think caused this? Can I decrypt the files on my phone somehow and restore them?
Thank you in advanced.

Had faced this many times. ...after trying diff options and failed Qualcome MSM method works perfectly.
Yep, You cant restore data i think as it being already formated as per knowd based on your steps above on diff posts

tabletalker7, can you please explain a little technical detail? If i follow your procedure, what is the difference from me just restoring boot, system and data from a Nandroid backup of a system that used to boot? What causes the restored system to no longer boot?
Because you seem to be suggesting a solution for the the problem I had. I normally do plenty of backups and play around with the system quite a lot, but Op6 burned me: I was unable to restore from a backup like I always did on other phones. I tried suggestions from other posters to no avail. So I set up a clean system from a fastboot rom and reinstalled everything from Titanium. I wonder, after I set pretty much identically, should I just risk and to once more try to restore from that Nandroid that was failing to restore (that only had system and data btw)? I'd greatly appreciate if you can enlighten.

1. Changing Android security updates makes changes to phone encryption. It will make the data itself on the backup unreadable to the operating system. That is why people playing with many different custom ROMs had problems with data stored on their phones.
2. By using the fastboot rom you ensure that both partitions have the same operating system. A/B partitioning seems like a great idea on paper but it seems to be executed in the most horrible way possible.

Thanks a lot. It is plausible and I remeber seeing folder names to which random hex strings were appended (I did not see file contents though). But after last restores I verified that the folder names in /data/data folder were looking allright. Twrp apparently could decrypt the data partition, but the system would still not boot. If I were to encypr the data partition I'd use the whole partition as one encrypted block and not bother doing it on file or folder basis, which is more error-prone. Another sourse of doubt is that I never played with OS version upgrades nor with installing other roms.
Can you also please answer the following? Do you think I can try to restore my boot+system to a different slot and then come back to my original slot if my playing there is unsuccesfull? Being scared that restoring a previous state can fail is a major problem.

I would not recommend doing that. While you may have different roms on different partitions you only have one data partition. That is asking for trouble

I would have data backed up, sure.
What bothers me is that an essential property of a digital automaton is that if you start it from the same state it will continue the same. Nandroid used to capture all that mattered for identical runs. It no longer does, something is missing, such as some encryption keys for data partition, as you seem to suggest. This bothers me.

What bothers you here are things I call "security". If the nandroid backup has the encryption keys to decrypt it, then the data is not secure.

Nandroid backups should be encrypted when created with a user supplied key. Twrp allowed this since ages ago. Not allowing the user to restore a backup is not a right substitution for this.

TWRP didn't do this. Android didn't do this. Ya know, if this is anywhere near as horrible for you as you are making it sound, my advise for you would be to buy Apple products. Bottom line is a new feature was added to Android, and your backup does work.

-It is as horrible as not being able to restore a full backup. No more, no less.
-Twrp has an ability to encrypt your backups, with your experience you must know this.
-You are suggesting someone to switch to iphone only because they point out that the things are wrong or dont add up.
-It is quite a common knowlege that you get good security out of encryption if you make things explicit and clear. And not how you may think it is. Cause you don't seem to know where the keys are stored for the data partition. Obviousely, because the phone eventually decrypts your data, the keys must be stored somewhere or derived from you swipe pattern.

Ok this is a giant pain in the backside but I have done this before and I know it works. Here is a step by step guide to restore.
1. https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665 go here and download the fastboot rom for the rom YOU HAD ON THE PHONE WHEN YOU MADE THE NANDROID BACKUP. Step by step on how to install it is there.
2. Install the rom and boot up the phone. Don't bother signing in to google or downloading apps or any of that. Just get through all the menus.
3. Install TWRP. Bluspark TWRP is recommended.
4. Install Magisk, but make sure IT IS THE SAME VERSION OF MAGISK AS WAS INSTALLED IN THE NANDROID BACKUP
5. Reboot to system and make sure the phone still works, then reboot to TWRP
6. Restore Nandroid backup.
I know this is a giant hassle, but it works every time. I haven't found a better way to restore a backup since this whole A/B partitioning started.

Following these instructions seems to be the only way of restoring a nandroid backup (at least for my Op6 bought on AliExpress from China). Important: step 1 wipes your sdcard, so the backup you want to restore must be on otg usb stick.
After spending many hours I managed to restore a backup at least once. Fortunately for me I have no plans of upgarding Android and will likely forever stick with the following set:
1) 5.1.11-OREO-OnePlus6Oxygen_22_OTA_015_all_1808102118_770880-FASTBOOT.zip (found here)
2) twrp-3.2.3-x_blu_spark_v9.85_op6.img + twrp-3.2.3-x_blu_spark_v9.85_op6.zip (found here)
3) Magisk-v18.1.zip (found here)
My plan is to fully debloat the phone and then I will keep everything unchanged for years, because nowadays updates are more about twisting your arms than giving you usefull features. I almost got to that state, but one little glitch forced me to roll back and the whole hell with the Nandoid backups on Op6 started.
PS: It's very interesting what is really going on with this A/B system. There must be a storage where the encryption keys are stored (if it is the encryption that does prevent the phone from restoring. Which I doubt because Twrp sees the files fine). There also probbaly stored what slot is used. That information does not get captured by the Nandroid backup.
(Btw, It seems that blu_spark Twrp is really NOT encrypting your backups with the passwod you supply. Official Twrp does. I have plenty of old encypted backups, from wich I could not extract any personal data (/data/data folder) but yesterday I could extract my private information from a backup done by blu_spark Twrp. This is serious iussue. I'll double check and will post if confirmed.)
Not confirmed, I was looking at unencrypoted file.
