Any issues using TWRP to reload backed up images? - Xiaomi Mi Max 3 Questions & Answers

Hi Guys,
I have used TWRP many times in the past to take a snapshop of everything on the phone for backup and also right before I do an upgrade.
This is the first phone I have dealt with that has encryption enabled by default and does make things in TWRP a little tricky.
So the question is with the encryption enabled can I still take a image backup of my working system (9.6.8.0) and then upgrade to MIUI 10. If MIUI 10 doesn't work correctly I want to be able to easily flash right back to the old image and be up and running again.
Thanks!

[Q] How to Root/use Recovery on a fully encrypted International Note 2 LTE?

Hi all,
I recently got a HK N7105 and because it lacked the possibility to use a french keyboard I upgraded to a stock unbranded ROM from Sweden (XXDLL1) and succesfully rooted with the relevant CF_autoroot through Odin. Also installed TWRP 2.3.3.1.
Then, I connected the Note 2 to my corporate exchange server which enforced a full encryption policy (device and external SD card) so I had to type in a password at each boot time (with a "nice" swedish prompt that took ma while to decypher), plus a password to unlock the screen. All was well as the root survived the process.
Next I upgraded to a later stock ROM from France (XXDLL4 from SFR) to try and get rid of the swedish prompt. That worked fine (and root was loast in the process, as expected) but I hated the branded stuff so much I reverted to XXDLL1 until a proper unbranded "english" or "french" ROM is available.
At this point I decided to root again. I was running XXDLL1 like the first time and used the same autoroot tar from Chainfire. Except my Note 2 was still encrypted and after that it would not accept my boot password (a four digit PIN) anymore so I was guted and had to factory reset and root then reinstall everything before reconnecting to the exchange server.
Question 1: Does anyone know of a safe, proven way to root a fully encrypted Samsung device so I can go another upgrade without having to wipe the device first?
Why reinstall everything? Why not backup everything first so you can restore after the wipe? Well, it so happens that no recovery (at least neither CWM or TWRP) can read any encrypted media on the Note 2 at the moment. And no Recovery can actually fully backup the device as well.
Question 2: Does anyone know of a proper way to handle this situation with minimum hassle?
So far, the best I can think of is doing a Titanium backup and FTP the files to my NAS so I can retrieve them later. But (Question 3) will this be enough to restore my phone to the expected state after a stock firmware upgrade?
Thanks in advance,
François

I think using Exynos Abuse apk will do the work

Thanks for the heads up, I'll look into it. But to be clear, that answers question 1, correct?

Yes that's a way to root the device.
Regarding encryption, very few people on xda seem to use it. So for that reason you'll have trouble finding out what works... I do use it though through choice so I can help you a bit.
When you encrypt the device, just consider /data to be off limits to anything not booted fully. That's why it asks you for your key in swedish - it can't see what language is in use until you unlock /data.
You will have issues using recovery with the device, since they can't read /data. You can use an external sd to perhaps load data to the device though.
I believe that TWRP might soon support the Samsung encryption on the device, meaning you could use it as recovery. Once you have a recovery that supports Samsung encryption, you should be able to consider it a fairly normal device.
Just be more cautious to backup your data as it is hard to recover if something goes wrong...
If your using stock rom 4.1.2, exynos abuse method of root will not work. It's been patched

Fine, I understand. As long as I have a way to recover my data if I need to wipe I'm okay... I just have to hope Titanium backup gives me that until TWRP can manage encruption on the Note 2.
I'm really waiting for a stock rom that boots in English or French now.

Not the case with xxdll1. When was it patched, xxdll4 or xxdll7?

I am on Stock 4.1.2 and Exynos Abuse did work on my device, it's successfully rooted using the Exynos AbuseAPK on 4.1.2 :good:
OK, now I have been experimenting a bit with backups and upgrade and have trouble restoring my device fully. Let me explain...
I got hold of a TWRP build that seems to handle Samsung encryption fine through one of the TWRP devs (thanks!), so I decided to go back and try to update my device.
Current ROM: N7105XXDLL1_N7105TLADLL1_N7105XXDLK7_HOME.tar (obtained from Samsung Updates)
New ROM: N7105XXDLL7_N7105OLBDLL2_N7105DXDLL1_HOME.tar (obtained from Samsung Updates)
First I performed a complete Titanium Backup on the device and pulled the files to my laptop using ADB.
Then I restarted into TWRP 2.4.0.0 (got a prompt for my password), performed a full backup and pulled the files to the laptop using ADB.
(for some reason, I could not install the new ROM from TWRP (unable to open ZIP), but the ZIP looked OK, as well as after a second download which TWRP since did not like, so I had to use Odin instead).
Next, I flashed DLL7 with Odin. It worked, asked for the password at boot, but the device was unrooted at this point (I expected that).
Then, I flashed CF-Auto-Root-t0lte-t0ltexx-gtn7105.tar from Odin, but the boot up password would not be accepted anymore as I already knew.
Tried to flash DLL7 again from Odin, same thing
Flashed TWRP back on recovery partition, but on startup it would not ask for password anymore and the external sdcard looked empty to it.
I then copied my backup to a different, non encrypted sdcard and could restore from TWRP but the password would still not work after reboot.
I did a factory reset, restored backup, same result.
At this point I decided to factory reset, wipe Dalvik and format /data. The format did the trick and after TWRP restore of my original back up the device booted up, did not ask for password and all my data was there. Except the Exchange account I use for Corporate email wants me to restore encryption in order to work (I expected that too).
Back at DLL1, so I flashed DLL7 again with Odin (OK), rooted the phone, triangled away the flash counter and reflashed TWRP to recovery.
I was where I wanted to be except for one thing: I need to restore Corporate access. But when I let it encryp the phone it does nothing. I let it through the night and nothing). And if I reboot the phone no password is needed at boot time, yet the phone seems to behave as if it thought the device was still encrypted...
I reflashed my original, full, backup (i.e DLL1) succesfully but Exchange still wants to encrypt my device. Isn't restore supposed to restore the encrypted /data I backed up?
At this point I'm left with possibly tryinjg to go back to full factory settings, not use the backup at all, encrypt the device then restore my data from the Titanium backup I made.
Is there a better option?
[edited jan 18 - TWRP/TB behaviour]
My comments apply to encrypted devices only! I am not trying to talk down TWRP or TB here, as they provide splendid performance on non encrypted devices. I have come upon hard time trying to upgrade/restore an encrypted device using thoise tools, that's all
For those considering upgrading & re-rooting encrypted devices, don't!
I am finding the hard way that this is a one way street. At this point, my TWRP made full backup does not restore the device to the expected status. Each time I apply it, subsequent bootup takes several minutes and I end up going through the initial setup procedure. It seems the device for some reasoin goes through a complete reset procedure.
[edit]
Clarification: The TWRP build I use, 2.4.0.0 is an alpha build and I was not current when I restored my backup. I so happens that it was overwriting the encryption header on the partition, which messed things up bad, and had issues writing back the data partition, ending up in a factory reset status!
Using the latest drop as of today (jan 27) I was able to restore my original backup and am now back to my original state. All is well.
[/edit]
Titanium Backup is none better. It keeps telling me that my Android ID has changed, a host of system applications start to fail when I try to restore and generally speaking I have now spent between a good 20 hours trying to simply restore my data.
[edit]
this behaviour is probably linked to encryption. I know for a fact that TB works very well on non encrypted phones. The 20h figure is overall, not just with TB.
[/edit]
The end story is: root before you encrypt, and either don't upgrade or don't re-root if you do! If you do, be prepared for some rough times...
Unless someone has a cleat idea of how to do this properly without losing all your data, that is.

I have had no issues despite doing upgrades, with and without wipes.
Titanium is fine, just stop restoring system app data. Seriously, what data do you have in a system app that you want to restore.
Restore your user apps, their data, and the xml based call, sms, Wifi backups. It will work fine.
Device ID isn't a problem - it's just trying to help you.

Sorry if I came across dissing Titanium Backup and/or TWRP. This was not the intent... I am sure both tools work real nice in general cases (and I have had success restoring data on a Jetstream before).
My main issue here is _full device encryption_ enforced by my company's corporate IT to allow me on the corporate exchange server. Do you have full device encryption on?
On my device, even after a full wipe and flashing a fresh stock rom Titanium Backup just did not work as I hoped. When I had to confirm individual popups of apps closing unexpectedly while it was proceeding and got nothing back in the end, what was I supposed to think? It could be that I don't understand how TB works... I was neither able to restore missing apps after the flash (missing apps: 0) nor installed apps data (they would close unexpectedly when started after restoring the back up). So I say: until full operation of TB on encrypted devices is documented, I will stay away from it, even though I am a registered user (and I do not plan to seek reimbursment)!
Anyway, I got to a belated happy ending (previous post edited).

Yup I use device encryption Enabled manually, but it's the same encryption.
You should find that titanium shouldn't even be aware of it - the encryption is transparent!
I wonder... I'm sure lenny had that issue on a recent 4.1.2 "stock" ROM... And he doesn't use encryption...
I personally have had no issues with titanium on an encrypted device anyway
I notice you were using the newest rom - that's the one lenny had issues on.

Exactly like I thought, encryption should be transparent to Titanium Backup since it runs within the OS.
I have had problems restoring into 4.1.2 DLL1 (the build I came from) and DLL7 (the one I was trying to go to)
The point is moot anyway since the DLL7 I tried was actually branded (Singtel stuff all around the launcher) and did not include French, which is why restoring my TWRP backup was a tempting proposition.
Good to know TB runs fine with encryption as well. What ROM are you running?

About a backup : have you tried Online Nandroid (Playstore) (or similar, based on Onandroid) ? This makes a CWM or TWRP compatible backup while the device is running (everything should be unencrypted at this moment).
See http://forum.xda-developers.com/showthread.php?t=1620255
About rooting : you can try the same trick as above, by using ADB-shell and pushing the needed files to root to the device while it is running.
For my S3 there is a Toolkit that automates all this (http://forum.xda-developers.com/showthread.php?t=1703488), maybe there is something similar for your device ?
If not, you should still be able to do it using manual ADB-pushing.
I'm sorry I can't give you detailed instructions about the rooting as I'm not familiar with your device. Search here on XDA and you'll find more details.

Thanks for the suggestions, and no I had not tried Online Nandroid as I was not aware of it. Anyway, my main issue is now resolved since TWRP has include support for Samsung TouchWiz based encryption in 2.4 and that works well.
For those interested, the only remaining issues I have with TWRP regarding encryption are that if you want to format /data from TWRP (say, to remove encryption) it will fail unless you _do not_ enter the password at boot, and the TWRP formated /data cannot be re-encrypted (you must use stock recovery to factory reset/wipe the device or else the encryption step will sit deat in the water doing nothing). I suppose the second one is a bug that will be fixed in a later version.
I will check Online Nandroid out anyway, being able to make a backup from a live system sounds good!

I have a similar issue. I had the device encrypted and decided to ROOT (using CF-AutoRoot). Unfortunately I cannot bypass the password screen now, although I know that I'm entering the right password. You are saying that if I flash TWRP everything will be fine?

Two separate things:
Root messing up encrypted touchwiz devices and twrp not handling touchwiz encrypted partitions properly.
The 2nd one, as much as I can tell, is fixed since before 2.5 so if youwork with the latest (2.6) you should be fine.
The first one I haven't played with in a while, but my finding is that you don't want to root a device once it's been encrypted. I've tried several different methods including rooting as you flag as is possible with twrp and all end up the same:the password is not recognised anymore!
The only thing that works for me is rooting before encrypting or only flashing pre-rooted ROMs.

Yes - I had to factory reset the phone and format the SD Card. Never root AFTER encryption :silly:

Bootloop at green HTC Boot Animation after trying to restore TWRP

Hello,
sorry if this has been mentioned anywhere before, but I wasn't able to find something similar.
So I know why way around with my old Nexus 5 in things backing up the phone with Titanium or TWRP, but since it's wifi module died on me I switchted to the HTC 10, which is kinda intimidating to me when it comes to updating to new OS or backing up. With the NExus 5 it was a walk in the park for me.
First, I don't really understand the concept of S-On and S-Off. Don't know if this is related to my problem, just wanted to mention it.
My HTC 10 is rooted, bootloader unlocked, S-On and runs on 7.0 2.41.401.41.
TWRP is the latest available version.
Before I rooted the phone I made a backup of the stock system image etc like explained in one of those "how to root the htc 10" tutorials (no writing allowed).
To root I had to allow writing onto the system partition of course.
Now, I made an TWRP backup. I backed up everything that was available in TWRP. Userdata, cache, system etc.
Few weeks ago I ran into some problems (I though I did, turned out Google App is just weird) and wanted to restore my TWRP backup.
So I did. Went to TWRP and restored the backup from my SD card.
Got no error messages during the process, but when I wanted to boot up the phone the green HTC boot animation did its thing and then froze at the HTC logo, which would result in a bootloop after ~10 minutes of waiting.
Could force the phone to go into bootloader and from there into TWRP, but that's the best I could do.
Also removed SD and SIM card trays, but that didnt do anything.
Had to factory reset and then do a backup via Titanium backup, which is better than nothing but still a pain in the a** because some things just have to be set up manually, which took me quite a while. I honestly don't want do that again anytime soon
Does anyone have an idea what could went wrong or what I did wrong during the backing up and restoring process?
Except for that, I tried to understand how to update to an upcoming version of the OS when the phone is rooted with S-On and how I could keep my userdata? On the Nexus 5 I just manually installed everything via adb except userdata.img and only had to re-root the phone afterwards. I am afraid this isn't possible with the HTC 10, am I right?
The HTC 10 forces encryption and that has broken TWRP restore for me if I try to switch between ROMs. If I switch ROMs then I have to do a full wipe / format. The one time I tried to go back to my original OS I had a similar issue and I ended up flashing the full RUU to get back to stock.
The only time I am able to restore in TWRP is if I'm returning to the same ROM that I am currently running. Even then I usually just restore the data.

Android Q beta2 Rollback

Hi all
Does anyone know the best way to roll back from updating to AndroidQ?
I have issues (android auto, casting etc) so would like to roll back to the lastest stable release
I am having a right pain restoring to to anything at the moment
Thanks

Yeah you can either use the "flash-all.bat" file that comes in the android p stock image zip or fastboot boot twrp.img and once booted into twrp just restore a backup. But you'll need to create a folder on you sdcard called TWRP. Then put a backup in it. I've even booted twrp then flashed pixel dust. It's not as critical as it was years ago when once you went up bootloader then downgraded which would cause bricking. At least I haven't run into any issues. Just make sure you turn off any lock screens and have "USB debugging" enabled.
If you are enrolled in the beta, just opt out on the website where you opted in. You'll get an OTA, which will wipe your device, so back up first. Just did this last night. Couldn't have gone any more smoothly.
For some odd reason when I rolled back my battery refuses to charge up to 100% any one else having this issue?
You have to have your phone unlocked... Yes, you will lose everything from internal memory, but can restore all your apps and settings.
I made this path twice, on beta 1 and now on beta 2.
First, make sure you have twrp. Back up on twrp everything but you will need only the data partition. Also don't forget to backup your internal memory (different from the data partition).
After that, just flash normally the last factory image from Pie, or at least the same version that you have on your nandroid backup.
After finish the installation, install again twrp. Go into twrp and restore ONLY the data partition!!! You can also restore the boot if you like (if you had magisk installed for instance). This worked flawless with me.
I repeat, no use if you try to restore ALL partitions on twrp!! At least with me, twrp would just reboot in the middle of restoring the system partition (no idea why that happened on beta 1 and now on 2). Second, the same if you try to flash factory image without the -w (without wiping internal memory), it just reboot every time it tries to enter android.

This is a bug that was fixed in Q. You can alternatively fix it in pie by flashing a kernel that has Q patches merged in.

Tinkering with Redmi Note 5, flashing TWRP, trying to enable Camera2, bootloop...

Hello there,
I've recently received my Redmi Note 5 back from warranty service. As much as I like the phone, one thing I always found really disappointing about it is that for whatever reason, it is, as far as I know, the only phone from the Redmi Note series that has Camera2 disabled by default, preventing me from installing GCam. Fortunately, I have found multiple tutorials on how to activate it. Since I've wiped my data before sending it, now was the best time to do some tinkering.
I've used my friend's laptop to unlock its bootloader and install TWRP (it refused to work on my desktop for some reason). the official TWRP web page warned me that the phone uses dm-verity, which is something none of the tutorials mentioned. After some further digging, I found out that should I mess with it, the phone would simply revert any changes, and to prevent this, I needed to flash a dm-verity disabler, such as LazyFlasher
Thinking nothing would go wrong, I decided to try flashing TWRP and deal with the system replacing it with the stock recovery later. All went as planned, and the phone booted into the custom recovery with no issues. It asked me for a password to decrypt the internal storage, which I don't know, so I skipped this step. The first thing I did was creating a backup.
I then tried rebooting, just to see if it would really revert the changes. It did, but it didn't go as smoothly as I had hoped. The system became laggy to the point where it was basically unusable, often freezing for more than 30 seconds after just opening an app. Not knowing what to do, I flashed TWRP back, this time with the dm-verity disabler. A tutorial on how to do this that I found recommended I wipe the cache after flashing the tool. I tried doing that, but the process failed immediately. I rebooted the phone, and the next thing you know, I'm in a bootloop. I've let it sit for a while, but even after some time, the system wouldn't start. Fortunately, I was still able to get back into TWRP.
I restored the backup I created earlier. This, for the most part, solved my issues, the system works fine-ish again (aside from an occasional lag, but it's not nearly as bad as it was) and isn't trying to replace TWRP with the stock recovery anymore, but I'm kinda afraid to tinker with it again. I'd really hate having to buy a new phone just because I bricked the one I have (and I didn't even get to flash the tool that was meant to enable Camera2).
What did I do wrong? Should I've formated the internal storage to gain access to it first? Did flashing TWRP without dm-verity disabled somehow mess up the system? Would flashing a custom ROM bypass having to disable it? I'm confused...

Bluetooth problem after flashing TWRP

Hi,
I flashed TWRP on my unlocked Redmi Note 8T with MIUI Global 12.5.5. Everything was great until I rebooted it and saw Bluetooth error which pops every time I try to turn Bluetooth on or just randomly during usage of the device. I also tried to re-flas TWRP with Orange fox but it unfortunatelly did not help. Now I have no idea what to do but there are also some other people with this problem (for example:
https://www.reddit.com/r/Xiaomi/comments/y9zsak
).
Does anybody know any solution? Thanks!
Btw Orange fox is for ginko devices, I did not find version for willow
I had the exact same problem when I tried to root my stock rom in ginkgo. I was getting a lot of "app keeps stopping" pop ups, and that also included bt. My bt was completely broken until I changed rom. Also I'm guessing this had happened when I had rooted my phone with magisk, not by flashing recovery itself. Perhaps you could try to uninstall magsik, and see it it resolves the issue for you. If that would be the case, then you would have found your problem, and maybe you can flash a custom rom to safely root your phone.
Thanks for reply, but i did not have magisk flashed on my phone. I only had installed the app, prepared apk file and did nothing in TWRP (Orange fox) , just flashed a recovery with my PC, checked that it is working and rebooted device. Anyway I tried to do it only because of acces to NFC and Gpay which is now blocked.
As you also said, I would like to try custom rom (like LineageOS) because it seems like bad idea to have a stock room on an unlocked phone. Only the problem is how to backup data like data from apps, games etc.
So now it tried one of my ideas, which was to install Magisk (root) and uninstall it but it also did not help (I expected that)

To backup data simply copy your personal files in pc or sdcard. And to backup data in apps, take back-up of only those apps and where you need to backup. Don't take a complete backup using some app. That consumes a lot of space and make the newly rom feel "not so new". Most apps don't require you to take back-up offline these days. I usually backup only my personal files before flashing rom.
Yeah, that's true. But don't you know how to backup data from these "offline" apps? I was trying to solve this also before unpocking bootloader like a year ago but unsuccessfuly.
Also, which rom should I choose? I'm deciding between LineageOS and Pixel experience.
So I have LOS installed but I can´t install other zip files (like Google apps). Im only getting error: signature verification failed while. Im using LOS recovery so where is the problem?
Solved it!
Hey @vasik006 ! I know this is very late and you might have found the solution yourself, but I found the solution to this problem. Since yesterday I was trying to root my ginkgo with twrp, using magisk delta and had exact same issue. Joyose and bluetooth keeps stopping, and don't work. Simply factory reset ( I also formatted data) in twrp, and in next boot bluetooth should work. Then you can simply install the magisk apk and let it do its thing. No need to flash again since it has already made changes to boot file that can't be overriden by resetting phone.
Thanks, this might help someone else with this problem. I have already formatted my phone, installed Lineage OS and everything is ok
For me, the problem with BT and Joyose occurs only with TWRP v3.7.x. I went back to TWRP v3.6.1_9-0 but now backups are not working.

I have the same problem with the Redmi note 8. Did you unroot first or did the factory reset directly? Tks

no need to unroot. simple factory reset the device and you're done.

TWRP is invaluable for backing up the system before making changes like theming etc. and I can take a TWRP backup to any of my (all the same) devices and restore the whole thing in just a few minutes. So convenient! I really couldn't imagine life without TWRP. TWRP enables me to clone my device in case of hardware failure. All my settings and all my apps and all my custom configurations which would otherwise take hours/days to setup - BAM! Presto! on the new device and running perfectly.
TWRP + NeoBackup are essential. TWRP as described, and NeoBackup to roll back breaking updates to apps when devs butcher them, break them, and/or just remove really useful features. I also disconnect apps that get ruined by an update from the Play Store so they don't keep coming up when I check for updates.

I would advise you to read the posts again. They were asking about how to take backup of "personal apps" which twrp can't do, and if they are changing ROM then twrp backup won't be of any use to them. Therefore, whatever you're trying to tell here doesn't really help the discussion.

TWRP does backup personal apps and their settings. Once you restore a TWRP backup, you have everything back except media files - images, videos, documents, etc. The launcher icons, the apps, the system settings - everything is a perfect clone which you can restore on a new device (same model, of course).
I actually came across this thread searching to see if others had a problem where merely flashing TWRP caused Bluetooth to crash (and Atmos).
Use OrangeFox
is there anyone use BT-fix-for-PE-20190618.zip to fix this problem ?
I'm on an ROG Phone II with the same issue.
The "fix" is to wipe in TWRP and install Magisk BEFORE you leave for your first boot and NEVER come back to TWRP as the issue will return the second recovery is booted.

From what I can tell, this is correct. 3.6_XX-X allows me to come and go from TWRP as much as I please without incurring the bug, however, I haven't tested backup though I can't see a reason why they wouldn't work.
Are these existing backups that aren't working or the whole backup function in general?

It looks like this guy didn't have any luck with it either. It may be divice specific

It seems to be a twrp issue. What version do you have? And what version of magisk do you have?
I have recently flashed miui 12 (android 10) after bricking the phone using qtel. I noticed the Bluetooth problem last week and didn't find a fix. I have twrp 3.6.2 and magisk 25.1. I had twrp 3.7.1 but if failed to decrypt data using pattern so I rolled back to 3.6.2. And I thought that magisk had to do with the Bluetooth problem so I rolled back to 25.1 from 26.
I still can't use the Bluetooth, and I don't have time to reset the phone, I just finished restoring everything
I CAN CONFIRM
go back to the previous twrp 3.6.2 version + wipe factory reset or simply format data solve sucesfuly solve installation issue of Magisk 26.1 or Magisk Delta 25210

I can't afford resetting my phone right now , don't have enough time. I'll let it like that for some months.
Edit : I have miui 12.0.6 installed (android 10) and I'm not planning to upgrade since I have much better battery life (even better than every mod I tried). I wander if I flash miui rom from recovery can fix it?
Edit 2: flashing the rom from recovery didn't fix it
