[Q] Move from CM-11 to CM-13

I have CM-11 (2016-08-15 nightly) installed on my HD+, along with CWM recovery "6046", and am happy with it. However, my other Android devices have Android 6.0, so I thought I'd consider CM-13. Questions:
Is moving to TWRP a requirement? I see statements that CWM recovery is no longer in active development. So what? Are changes being made (see next item) just for the sake of change (a popular activity in software development), or are there real advances that TWRP enables?
In preparation, I downloaded the cm_ovation-ota-MOB31K.161125.zip and open_gapps-arm-6.0-nano-20170117.zip files. I was astounded by the sixe of the latter. What is with the "Open Gapps" files??? I note that the pico one for v4.4 is 2.5 times the size of the one I have been using ( pa_gapps-modular-pico-4.4.4-20141110-signed.zip ). I thought these were supposed to be basic, minimal files.
I'm looking for an install procedure from CM-11. I assume that just means upgrade to TRWP if necessary, and then just use that to install the above zip. I see no discussions of this in this subforum; is it all over in the "Development" forum?
What is the performance of CM-13 like, and is it now stable enough for daily use? I see a long thread peppered with "thank you"s that started two years ago, and I'm wondering if there's anything more succinct.

FWIW -- I had enjoyed good performance CM11 until about mid last year when many commonly used apps started to become unresponsive and oftentime crashed (force-closed). So over the holidays break I took the plunge and upgraded to Amaces' LN14.1 experimental build lnos_ovation-ota-NMF26Q.170104, so far the performance is as good as it used to be with CM11.

Every major release of CM, starting from CM7 -> CM9 -> CM10 to CM11, has required a new and non-backward compatible version of CWM.
I don't believe that CWM 6.0.4.6 can flash CM12 and CM13, and you can find pointers on what recovery versions are needed and are available at https://forum.xda-developers.com/nook-hd/development/boot-sd-external-recoveries-twrp-2-8-3-t3314870.

I used the minimalist pico package, and then added afterward a couple of missing essential apps like Google Maps.

The most straightforward route which I found and used is to create a SD-based recovery using the pre-packaged SD image available at https://notredame.app.box.com/s/26a4bygh9vbaw7jjq08xr5evomvaw5ww/1/3332706778, just unzip and burn the image to SD then add to the card the ROM, GApps, and (EMMC) TWRP zip files you wish to flash. Then boot up the SD card into TWRP, (optionally backup your CM11 ROM system & data), do "wipe /data & factory reset", and flash the 3 zip files and you are set to go.
Alternatively you can try to use a similar approach as outlined at https://forum.xda-developers.com/nook-hd/general/how-to-updating-hd-hd-internal-emmc-to-t2863171 -- i.e., use CWM 6.0.4.6 to flash new TWRP then boot into the new TWRP to wipe and flash new ROM and GApps. This was the route I took when I upgraded to CM12.1 to try it out.

Thanks very much for the info! That's what I did, and it was simple and (reasonably) quick. I note that CM wants to go ahead and install the CWM recovery. I assume I should not let it do so.
Now, to get Titanium Backup to think it's got root. This appears to be a bit of silliness. I tried several "superuser" apps (including the "phh" one), to no avail so far ...
Edit: OK, here it is ...
belfastraven said:
There is still a "bug" I believe, in that when the cm/ln rom is first installed on a device with a clean data partition (after a wipe or factory reset), even though developer options will say you have root, you actually don't. Changing the root selection to something else and then changing it back causes the necessary system file to be created. As long as you don't wipe data, you will not have to do this again on dirty flashes. What is new in the last few months is that, accessible through developer options, there is a rudimentary root manager available in the rom, where you can determine how root requests from various applications should be handled and see which apps have requested root access.

[RECOVERY] [TREBLE] [RETIRED] TWRP with Tissot Manager (Treble & Dual boot support)

RETIRED! No longer supported or being developed. @Giovix92 is now the lead dev, please use his TWRP for full compatibility with modern kernels/ROM's - https://forum.xda-developers.com/mi-a1/development/recovery-twrp-3-3-1-0-tissot-manager-t3976117
Old thread below:
-----------------------------------
About
This is a TWRP Installer ZIP and bootable IMG with extra capability such as Treble-izing, Dual boot repartitioning and other power-user tools with integrated Aroma Installer-powered GUI screens that I call Tissot Manager.
HIGHLY recommended reading and guide for everyone new to Treble - [TREBLE][GUIDE] From Stock to Treble - everything you need to know!. It also has some general protips hidden within there, for example the seamless/slot system interactions and nuances, so it's worth reading for anyone who wants to be a master of the Android flashing domain
Features:
TWRP fully Treble-ready with dual-boot ROM patcher;
Maintained with latest TWRP version;
Fully compatible with non-Treble devices - can be used as normal without Treble partitioning;
USB-OTG fixed
Has 'TWRP survival' function for automatically re-installing TWRP recovery when installing ROMs and kernels;
Option to install a payload ROM in the current slot, rather than the inactive one;
Option to ignore Payload<>Recovery certificate failures (fix for newer LOS-based ROMs);
Adds a "Tissot Manager" Aroma GUI to TWRP Advanced Menu (bottom-right button), which is the tool used to repartition the device for Treble and Dual boot, as well as some other nifty stuff:
Has the option to shrink System OR Userdata to create Vendor partitions. All relevant partitions will be resized and formatted in one go.
If you shrink System, you will keep max size Userdata - however it will be incompatible with non-Treble ROM's (they will crash on installing with Error 28 due to System being too small). It will Erase system, requiring you to reinstall a ROM or restore a ROM backup.
If you shrink Userdata, it will ERASE DATA AND INTERNAL STORAGE COMPLETELY - but your device will stay compatible with all existing non-Treble ROM's
Dual boot requires Userdata shrink and works by splitting into userdata_a and userdata_b. The partition split size is customizable during the repartition process.
Adds a "Patches" section with the following current options:
Patch the current Vendor for dual-boot capability (only required if automatic patching wasn't possible). See the 'About Dual-boot' section below for more information.
Enable an insecure ADBD on boot for the current slot (i.e. enable debugging and remove authentication requirement). Useful for ROM hackers/porters.
Patch the current slot to enable/disable forced userdata encryption
All of this info is detailed inside the Tissot Manager GUI.
See screenshots in post 2.
Instructions
Optionally boot the boot-recovery.img to get a temporary TWRP if you don't have it installed, unzipped from TWRP-boot.img-3.2.1-with-Tissot-Manager-x.x.zip:
Code:
fastboot boot boot-recovery.img
Warning - do not EVER flash this img - hotboot it only.
Flash the TWRP Installer. Any slot, any ROM, any existing Recovery - it doesn't matter - it will be installed to both slot kernels.
Reboot Recovery
Optional - Use the "Advanced > Tissot Manager" option for repartition options and other advanced ROM patches (Aroma Installer powered GUI - a fully guided and interactive process).
If you opted to repartition for Treble, you are ready to flash a Treble ROM/Vendor pack. Reminder - check out my full guide for learning and instructions on all things Treble.
About TWRP survival
TWRP survival is a simple hook that detects if a boot.img will be installed and restores TWRP after it's flashed. This only works if you have booted TWRP with Tissot Manager 2.0 from a real recovery boot - NOT from a recovery 'hot boot' (fastboot boot method).
You will see in the install log if a TWRP survival attempt is successful in the flash text output.
Automatic TWRP survival works when:
Flashing a ROM ZIP (or AIO) with TWRP
Flashing a boot.img in TWRP "Install Image" mode
Automatic TWRP survival does NOT work when:
Flashing a boot.img via fastboot
Restoring boot in a TWRP backup
Any other way of flashing a boot.img
In these cases, be sure the use the TWRP Installer immediately after flashing or restoring a backup - otherwise you may get the device into a confused state (especially if you restore a non-TWRP boot then try to install an AIO ROM without installing a new TWRP first).
About Dual-boot
Dual-boot on this device is relatively simple. As you know we have Slots - boot_a and _b, system_a and _b and vendor_a and _b (for Treble). This repartition splits userdata into userdata_a and _b too. You can simply change your Slot in TWRP reboot menu to change which ROM to boot.
This is designed for developers and testers - NOT for daily use. There are some significant issues with dual boot systems:
Any kind of security lock (PIN, fingerprint, etc.) set on one ROM will cause the other ROM to believe it has security too, but constantly fail with unlocking. This is reportedly because security info is stored on persist, which is shared between each slot (and not compatible with differing ROM's).
Because Userdata is split, so is Internal Storage. In TWRP, when changing slots, the MTP will remain mounted to the old slot - it must be manually disabled and renabled (Mounts menu) to update to the new slot.
I will not fix these issues - dual-boot is not designed to be for general/daily use and there may be more minor issues that I don't know about. It's intended for developers only.
In order for a ROM to be dual-boot compatible, the fstab file (information given to Android about partitions to mount) needs a small modification. This TWRP can try to do this patching automatically when you install a ROM, or it can be done manually in Tissot Manager's Patches menu (as well as single-boot patch to e.g. revert a ROM backup from a dual-boot state).
You will see in the install log if a dual-boot patch attempt is successful in the flash text output.
Automatic dual-boot patch occurs only if necessary when:
Flashing an AIO Treble ROM ZIP with TWRP
Flashing a vendor.img in TWRP "Install Image" mode
Automatic dual-boot patch does NOT work when:
Flashing a vendor.img via fastboot
Restoring vendor in a TWRP backup
Any other way of flashing a vendor
In any of these cases, you can manually patch Vendor for Dual Boot in Tissot Manager's Patches menu. You can also remove dualboot support the same way. It will detect the dualboot state of the current Vendor slot and present the available option. If you find that it doesn't actually change after patching, the Vendor is incompatible (please report it to me). RR AIO Vendor is tested OK.

FAQ
Q) After I flash TWRP, I get kicked into a Recovery loop when trying to boot the ROM!
A) This is probably because you have a kernel that does not disable dm-verity. To fix this, flash Magisk. The void kernel included in RR AIO does not have this problem and can therefore be safely used without Magisk (for e.g. GSI compatibility).
Q) After I flash TWRP, I get kicked into fastboot when trying to boot the ROM!
A) Your kernel is not Treble-compatible.
Q) How do I update TWRP?
A) Just flash the ZIP installer again, then Reboot Recovery. Note that this will erase Magisk on BOTH slots if you have it installed to either, requiring you to reflash it to one/both slots. See my Treble guide FAQ section for more info on Magisk interaction.
Q) My PC can't see the MTP (storage) device from TWRP!
A) For dualboot compatibility, MTP is automatically disabled at various points. Just enable it manually in the Mounts menu to get access.
Q) If I shrink Userdata for Treble, will stock and OTA work?
A) I have heard varying results on this. It does for some, not for others. Please assume that this will NOT work. It will definitely not work if you have shrunk system.
Q) Can I restore a non-Treble TWRP backup after I repartition for Treble? And the other way around?
A) Yes! In fact, this is the easiest way for...
...using stock ROM on Treble repartition (requires Userdata shrink ONLY). May also require a custom kernel with dm-verity disabled (see Questions above regarding fastboot kick and recovery loop).
...using a non-treble ROM if you shrunk System instead of Userdata since you cannot install non-Treble ROM ZIPs with a shrunk System (see next Q)
Q) I get some Error 28 when trying to install a ROM when repartitioned
A) You have shrunk System and are trying to install a non-Treble ROM. This is not possible AT ALL because the ROM ZIP expects a stock-size System. Use Userdata shrink mode instead if you want to be able to use non-Treble ROM's easily.
Q) I see "Failed to mount '/system' (Device or resource busy)" red error in TWRP after flashing a ROM
A) You can safely ignore it. You just need to reboot recovery before you can flash anything else (like Gapps) to this ROM.

Good job! :good:

Nice work!
Did you tested treble roms with this? Aex now have treble support

Omg, you are the best man. @mohancm also huge thanks to u man, great devs in our XDA.

I have never seen this kind of detailed, kind guide in XDA. You guys are awesome! Thanks for all this work!
One question : If I choose to shrink /userdata instead of /system,
1. Will I be able to flash stock rom by using MiFlash?
2. If I can, will I be able to get OTA and install them w/o issues?
3. Can I restore a TWRP backup that was made before repartitioning?(because of data on /data)
I think lots of people will be wondering about #3. If you think so too, then please add it in OP!
Thanks to all of you devs again!

This is just the repartition part, one step of Treble. You still need a Vendor pack. But yes, this enables Treble ROMs and the ROMs require repartition.

1. If you do, it will wipe partition map back to stock. So you will need to repartition with Treble Manager TWRP again. But you can make a backup of stock ROM in TWRP and just restore it after the repartition. It should work.
2. Don't know. Needs testing.
3. Yes! I forgot to add this to the FAQ.

Has this tpwr f2fs support and working?
Since Los support It i would like ti have

@CosmicDan
Thank you so much for your effort. I'm currently on stock and want to retain stock compatibility, so I'm going to wait until this becomes more polished before trying. I understand that Treble is not meant to be compatible with stock, so I realize my question might be out of place. Still, my question is:
Will you also release the .img file for Treble TWRP for those of us who don't want a permanent custom recovery?

It's indeed not intended to be compatible with stock ROM, but your mileage may vary, and as @CosmicDan said, it might work good enough or it won't. You can only try to see the results yourself.
This whole Treble thing is meant mainly for custom ROMS, since stock will never be Treble compatible (still, anything could happen)

I've just updated the TWRP with Treble Manager to 1.1 which fixed a semi-important bug.
Also, I've released a guide for those who find the Treble conversion/install process confusing - check it out. If you can, keep TWRP and Treble Manager specific questions in this thread, but ask your general questions and help over there - I will update the guide as I get feedback

FAQ
Q) If I shrink Userdata for Treble, will stock and OTA work?
A) Untested. Please report your results. But Treble is really not about Stock, you will likely encounter more problems down the line or it may turn out to be completely incompatible.
Q) Can I restore a non-Treble TWRP backup after I repartition for Treble? And the other way around?
A) Yes! In fact, this is the easiest/only way for...
...using stock ROM on Treble repartition (requires Userdata shrink ONLY). May also require a custom kernel with dm-verity disabled (untested - if you get bootloop when using stock, it means you do) or Magisk (also untested, may still get bootloop).
...using a non-treble ROM if you shrunk System instead of Userdata since you cannot install non-Treble ZIP's on ROM's with a shrunk Userdata (see next Q)
Q) I get some Error 28 when trying to install a ROM when repartitioned
A) You have shrunk System and are trying to install a non-Treble ROM. This is not possible AT ALL because the ROM ZIP expects a stock-size System. Use Userdata shrink mode instead if you want to be able to use non-Treble ROM's easily.
Q) I see "Unable to mount '/vendor' (Invalid argument)" red error in this TWRP
A) You can safely ignore it. It just means you have not repartitioned your device for Treble yet, so it can't mount the /vendor image.

Ay!
Have just finished testing about OTA on stock after Treblizing!
Result?!?
OTA works perfectly on stock after shrinking data to Treblize! Hurrah! ???
Process I followed:
1) Treblize by shrinking data
2) This is important: flash stock ROM in fastboot using MiFlash! When flashing for the first time, select "clean all and lock"! No other standard options working! I couldn't even boot stock using other options!
I've tested by fastboot flashing April build and then updating it to May OTA!
*** On a note: clean all will erase everything on your phone including your personal data!
If you use "save user data" then stock can't even boot! This may caused by the encryption!
BTW, after everything I just restored my non-Treble RR backup and everything works perfect! Just Treble Check app can't check that it's Treblized!
But don't worry! Treble partition table still remains! Fastboot flash can't touch that and can't recognize that it actually exists! Which to me is a good thing!
@CosmicDan, give me a thanks buddy! I deserve this!

- Data backup is not working due to device encryption
How to Install
0. READ F.A.Q section first here
1. Unlock your bootloader
2. Boot to Odin mode
3. Check AP box and select TWRP tar file
4. Hit start
5. Reboot to TWRP and flash multi disabler if you want (check this before flashing it)
6. Have fun

TWRP 3.5.1_10 - Beta 2
Multi Disabler
Sources
TWRP device tree
Kernel source

Change Log:
Beta 2 - 24th of March 2021
- Update to latest kernel 4.14.190
- Fix MTP on the latest kernel
- Clean up dynamic partitions
- Released kernel 4.14.190 source
Beta 1 - 20th of March 2021
- Initial Release

F.A.Q:
What is data encryption and why doesn't it work on TWRP?
Samsung M51 uses file-based encryption that encrypts the user data partition.
By default, TWRP can't decrypt user data partition, which makes it impossible for us to access the internal device storage from TWRP or recovery MTP, which means you can't put ROM files on your internal phone storage and flash them from there.
What is Multi disabler and how does it affect your phone?
- Multi disabler disables and removes the encryption on the data partition, which makes it possible for you to access your internal storage from TWRP or recovery MTP. thus, making it possible for you to flash files from internal storage.
- Removing the encryption on your device's internal storage makes it possible for you to access your files from recovery directly, which makes it possible for anyone to access your private files without your permission from recovery.
- All of the above means that your device will be less secure. So if you care about device encryption then don't flash the multi disabler and use a USB OTG or a sdcard to flash ROMs, which I recommend. Otherwise, flash the multi disabler at your own risk!!!
- FLASHINF MULTI DISABLER REQUIRES PERFORMING A FULL DATA WIPE WHICH MEANS YOU WILL LOSE YOUR DATA. SO BACKUP YOUR DATA BEFORE FLASHING IT.
My device keeps rebooting to recovery after flashing TWRP, why?
Most probably you will need to wipe your data partition and flash multidisabler
Data backup is not working even after flashing multidisabller, why?
Current multidisabler still can't fully disable FBE encryption, which means that TWRP can't read data partition at all, hence creating backups will always fail.

Reserved just in case

Thank you so much for your efforts,
Does backup, restore, work smoothly in this version of twrp? Does it fully restore after making a backup? Or are there still mistakes?
In Twrp 3.4.0 Data backup is not loading. Nonoperating. But the system is loading.
Oh, thank you, thank you.

Currently I have no working ROM so I can't test back and restore functionality. But backing data should be working.. don't take that for granted tho..
It would be great if you can test that and report if it's working or not, or wait until I or someone else test that.

thank you for your efforts. i installed this twrp and flashed mutlidisabler. also formatted data before reboot. Unfortunately twrp does not allow to create backups. Cannot unmount system partition etc...Your android 10 TWRP version is creating and restoring backups allright. So for now have to continue using android 10!

backups will not work because of device encryption. Even after flashing mutldisabler, the device will keep encrypting the data.

prerooting won't solve encryption issues. Maybe when TWRP can be build using android 11, we can fix encryption issues or at least partially fix it.

Fyi -i have spare m51 device with android 11 installed. Ready to use it for any kind of twrp test builds. This is a good phone and we must have twrp for android 11 developed here. Thanks

Did you even read the FAQ section?
anyways, backups will fail because of data encryption

Does this TWRP require to format data after installing without Multi disabler?

Nope, but you may need to install multidisabler to prevent the phone from reverting back to stock recovery. Don't formate the data after flashing Multidisabler and see if the phone boots or not

well i already tested that twrp build and it does not allow to create backup (which is the main reason i need twrp to start with). i will test your lineage roms no problem. Do you think that twrp will work properly with lineage 18?

Yes! it's working without any problems with lineage 18

Installing, Updating, Backup and Restore Guide for OP6/6T

This is a bit late but why not. THIS IS A COMPILATION OF ALL THE OS METHODS YOU NEED FOR THE OP6/6T.
ENJOY my guide
DISCLAIMER:
*I am not responsible for bricked devices, damage to your device*
Sorry for a long list of methods, some work for others and some don't. But I recommend to pick a method and stick to it. Maybe read the part at the top as some have notes about mine or someone else's experience/recommendation. Don't skip steps and follow each step.
If stuck, just ask and I or anyone else will try and help
I am here to post methods for anyone who is interested/need help. I have tested these myself and helped others who may be struggling
Download
The guide has loads of files/ zips/ tools to use/flash/install. But no worries as everything can be downloaded and there are links AT THE BOTTOM OF THIS THREAD (NOT COMMENTS) to where to download:
SDK Platform Tools (Fastboot tools) from Developer Android
TWRP from mauronofrio
Magisk from topjohnwu
Gapps (Google Apps) from NikGapps. I recommend omni for ROMs that don't include Gapps.
Fastboot ROM for OP6 + OP6T from mauronofrio
MSMDownload tools for OP6 + OP6T from Some_Random_Username
IMPORTANT NOTES!
YOU REQUIRE Platform Tools (Fastboot Tools) IN ORDER TO USE THE METHODS IN THIS GUIDE AS TWRP NEEDS TO BE INSTALLED!
YOU NEED TO HAVE A UNLOCKED BOOTLOADER AS WELL!
For GAPPS, u can use the same or a updated version of the package. But has to be the same type u used to install it like (stock, full, Omni, basic, etc). ONLY FLASH/INSTALL IF the RESTORE SCRIPT DIDN'T SHOW UP during a DIRTY FLASH/UPDATE AND ONLY FLASH AFTER REBOOTING TO RECOVERY AFTER FLASHING/INSTALLING A OS/BUILD ZIP FILE!
How to get Platform Tools
These tools are used to install TWRP, to unlock the bootloader of your device and is needed to use the METHODS in this guide.
Download the platform tools.zip of your software platform (Mac, Windows, Linux)
Extract the platform-tools.zip
To use it go into your platform-tools folder
Press shift + right-click and choose command prompt or PowerShell
Connect your device when it's in fastboot mode and done
How to install TWRP
Sadly this Guide is for Windows, but other platforms like Mac or Linux can be found online.
YOU CAN USE THIS METHOD TO INSTALL A NEWER VERSION OF TWRP TOO
You need to have downloaded Platform Tools which the link is attached below.
Transfer the TWRP.img file into the platform-tools folder
Now transfer TWRP.zip into your device's internal storage. (connect -> allow file transfer -> drag and drop files)
If you want root download and transfer magisk.apk and the link is supplied below. Also, RENAME from .apk to .zip
Now we must boot into fastboot mode. (Either do it with the advanced reboot in developer options or power off device -> boot recovery Vol - + power -> boot to bootloader or power off device -> press Vol Up + Vol down + power)
Now connect your device to a Windows device
Press shift + right-click. Choose command prompt or PowerShell
Enter "fastboot devices" and your device should be displayed if it's connected
Type "fastboot boot twrp" file name (do twrp + press tab) and press enter
Then you should be booted into TWRP
Enter the password and swipe to allow modifications
Press install and find your TWRP.zip file
Swipe to confirm Flash
If you want root do this
Press the back arrow and find your magisk.zip
Swipe to confirm Flash
Reboot to the system and done
Otherwise, just reboot to system. Up to u
Installing a Custom ROM
Install Custom ROM on OP6T from OOS
Make sure u have BACKED UP your device and have the latest OOS installed in both slots. If u do, go to Method 3.
If u have finalize.zip, go to Method 2.
Method 1
If u don't have OOS installed in both slots or finalize.zip, use this method.
Transfer OOS.zip file, TWRP.zip, Build.zip (Custom ROM zip file) into internal storage.
Boot to Bootloader
Boot TWRP
Flash OOS + TWRP
reboot recovery
Flash OOS + TWRP
Reboot recovery
Flash Build.zip (Custom ROM zip file)
Flash TWRP
If the ROM doesn't have GApps included do this
Reboot to recovery
Flash Gapps if not included
Format data
Reboot to system
Otherwise, just Format data -> reboot to system. Up to u
If you want root do this
Reboot to recovery
Flash Magisk
Reboot to system and done
Otherwise, just reboot to system. Up to u
Method 2
If u have finalize.zip, do this method. Using finalize is way quicker as there's less flashing and rebooting.
Transfer OOS.zip file, finalize.zip, TWRP.zip, Build.zip (Custom ROM zip file) into internal storage.
Boot to Bootloader
Boot to TWRP
Flash OOS + finalize
Boot to Bootloader
Boot to TWRP
Flash Build.zip (Custom ROM zip file)

Otherwise, just Format data -> reboot to system. Up to u
If you want root do this
Reboot to recovery
Flash Magisk
Reboot to system and done
Otherwise, just reboot to system. Up to u
Installing Custom Rom not from OOS
You can use finalize method or just flash OOS + TWRP way. The finalize way is there for some who like less flashing and rebooting.
Using the methods in Install Custom ROM on OP6T from OOS
Using the old way, use Method 1
Using finalize.zip, use Method 2
Remember to factory reset (wipe, but no need to wipe internal storage)
Backing Up OOS and Custom ROM
Make sure u have installed the latest TWRP version from mauronofrio
You should use TitaniumBackup or Migrate to back up your apps and contacts.
Also, have a copy of your Internal Storage folders if u have important files.
TWRP Backup backs up your OS like Apps, settings and set up, but not internal storage.
NEVER BACKUP SYSTEM AND VENDOR! ONLY SYSTEM.IMG or VENDOR.IMG IF YOU HAVE TO!
Restoring it makes going back way easier like you have never left
Or you can go manually and try and restore everything, but why do that when you got TWRP?
I do both ways of backing up
Backing up OOS
Boot TWRP recovery
Choose Backup
Choose boot, data. YOU DO NOT NEED TO BACKUP System.img and Vendor.img!
Swipe to backup
Once done, either boot to system or mount
Transfer the whole TWRP folder onto a storage device
Done
Backing up a Custom ROM
Boot TWRP recovery
Choose Backup
Choose boot, data, system.img, vendor.img
Swipe to backup
Once done, either boot to system or mount
Transfer the whole TWRP folder onto a storage device
Done
Restoring OOS and Custom ROM
Restoring OOS TWRP Backup
To restore OOS use either fastboot ROM or MSM. Fastboot is the fastest and easiest way if u have a TWRP backup which there's a method to how to make one in this guide. BUT if you are restoring to go back to stock OOS then use MSM
I use Fastboot ROM restore for that too as we are restoring our data anyways and also for switching/installing a custom ROM. Much easier in my experience.
DOWNLOAD FULL ZIP OF OOS version of your TWRP backup otherwise you could risk doing the whole restore method again OR setup from SCRATCH! IF you aren't restoring a TWRP backup, I recommend either TRANSFER or DOWNLOAD via WiFi or oxygen updater, a UPDATED version of OOS AFTER doing either fastboot ROM or MSM restore methods. As they restore a old version of OOS!
Restoring using Fastboot ROM
Download fastboot ROM of your choice using the link in the Download Link section.
Extract/ un-zip
Boot your device into fastboot mode (Either do it with the advanced reboot in developer options or power off device -> boot recovery Vol - + power -> boot to bootloader or power off device -> press Vol Up + Vol down + power)
Click flash-all.bat
Restoring using MSM Download Tool
Download latest MSM version of your choice using the link in the Download Link section.
Extract/ un-zip
Click on MSM tool .exe file
Turn off device
HOLD BOTH volume buttons
Connect your phone
Wait for your device to be connected and it should show as green
Click verify to check and press start
Wait till phone reboots
The setup device and u can carrying on restoring your device if u don't want a unlock bootloader or return to what your device was like before.
Go into developer options
Allow OEM unlocking
Reboot to bootloader
Enter "fastboot devices" to check your device is connected
Enter "fastboot oem unlock"
Swipe for yes
Then it will reboot again
continue to the next method
For both fastboot and MSM
Once booted into system, set it up and update to OOS version of your TWRP backup.
Download the full zip using the link in the Download Link section.
Transfer the OOS .zip to internal storage.
Go into settings -> system update -> Update via local upgrade -> find zip file and press install
Do this twice to make sure you have installed that version of OOS in both slots
Boot to bootloader
Boot TWRP
Install TWRP
Reboot recovery
Transfer whole TWRP Folder into internal storage
Restore only boot and data
Swipe to restore
If you have backed up your internal storage folders do this
Reboot to recovery
Transfer all your internal storage folders
Reboot to system and done
Otherwise, just reboot to system. U can update OOS as well if it's outdated. The method is below to update OOS with ROOT. Up to u
RESTORING TWRP BACKUP HAS ISSUES ON THESE ROMs
CrDroid (Method 1 + 2 don't work). Method 3 works (install Gapps if the ROM doesn't have it!)
Restoring a Custom ROM TWRP backup 1

The first method didn't work for me. But this method did
Restore fresh like you're going back to OOS.
Choose one method. Fastboot or MSM method.
I prefer the fastboot method.
Download fastboot ROM using the link in the Download Link section.
Extract/ un-zip
Boot your device into fastboot mode (Either do it with the advanced reboot in developer options or power off device -> boot recovery Vol - + power -> boot to bootloader or power off device -> press Vol Up + Vol down + power)

Restore everything (System.img, vendor.img, boot.img and data)
Swipe to restore. If data couldn't restore then boot system, setup system, boot TWRP and restore data.
Reboot system. The first reboot might go dodgy and it did for me.
Reboot system and transfer all your internal storage stuff
done
If this did not work still. Then do the 3rd method...
Restoring a Custom ROM TWRP backup 3
If the previous 2 methods has failed for you. Then try this.
Restore fresh like you're going back to OOS.
Choose one method. Fastboot or MSM method.
I prefer the fastboot method.
Download fastboot ROM using the link in the Download Link section.
Extract/ un-zip
Boot your device into fastboot mode (Either do it with the advanced reboot in developer options or power off device -> boot recovery Vol - + power -> boot to bootloader or power off device -> press Vol Up + Vol down + power)

If it still fails, repeat steps 1 to 15. But restore everything and you should be back on your custom ROM like you never left.
Updating OOS and Custom ROM
Update OOS with Root (Magisk)
Always do a TWRP backup before updating your OS in case
Download the full zip file of the latest OOS, transfer the zip file to internal storage NOT IN ANY FOLDER

Hey Guys,
Need a some expert advice please.
Long story short. I need to replace my OP 6T McLaren's battery as I have serious degradation in battery capacity (73% Serious Loss), meaning the battery is no longer charging to 3700mAh, max charging atm is around 2600mAh, which it drains very quickly. FYI Anything above 80% is the limit for average performance, >90% is best. You can use the OP Diagnostic App 1.0.0.9 to determine your own status. Does not work on all OP devices above 6 btw. Maybe other versions work. Anyway, will be getting OP to change the battery (no real local guys I can trust tbh, all Sammy & Apple guys...) and they want me to Factory Reset the device (complete wipe including internal storage (backed up already to PC)) before sending the device to the OP Repair Center for the obvious reasons of Privacy & Security.
On my device, I have a suite of apps that are no longer available to install with APK specially Signed, but won't be able to re-install (long story & can discuss in a PM more if there is an interest to help on this). These APK will not work any other way, I've tried! This being said, I know that TWRP Nandroids work well & have been doing these backups for yrs and have restored backups with these apps installed and it works! But I have not had to restore any as of late and TWRP Backup has somewhat changed in regards to the partition selections available. See TWRP Options pic below.
When OP returns the device to me, it will mostly likely be on the latest release of 10.3.11 (Hopefully).
Here is the current setup and runs perfectly!
OOS 10.3.11
TWRP: twrp-3.5.2_9-0-fajita
Magisk 23
The last Nandroid done today (No PW for good measure, but secured locally offline), I selected all partitions. Is this the best way to insure I get my full device backup restored?

I'm guessing that I will have to, Unlock the Bootloader, reinstall TWRP same version the Nandroid was created with in order to restore that backup.
Looking forward to hearing from you guys to make the best decision before proceed with the factory reset.
Thanking you all in advance for your time & assistance!
Cheers!

Idk if u have read Mauronofrio's XDA thread on TWRP backups. BUT NEVER BACKUP OR RESTORE SYSTEM OR VENDOR! From my guide, you don't need to backup vendor.img or system.img or anything else that's not Boot or Data FOR OOS. Make sure you have everything like a copy of everything folder/file in your internal storage before u wipe it.
BUT because you're going to wipe your device. U should have a copy of everything in case but don't backup system or vendor as they're useless and will crash your system if u restore those!
After you've got your device from repair, follow my method to restore OOS TWRP backup on your device and YOU'LL only NEED TO RESTORE BOOT + DATA. Once you have booted back to your system, everything should be there like you never left, but transfer your internal storage stuff as some apps store files in your internal storage. Once that is done, that should be it and it would be like you've never left
If the TWRP backup restore doesn't work let me know, but from my experience with going back to OOS via my TWRP backup I only backed up and restored boot + data for OOS. Custom ROMs are different but isn't the case for you

Wow, thanks for the quick reply!
I have not read Mauronofrio thread and will do!
I completely missed the system & vendor piece in your instructions....my bad!
So just to confirm, my backup that I have done with all checked off is good, but only restore Boot & Data with an exact duplicate of the current Internal Storage...right?
Going forward, when creating the Backup, just select Boot & Data and I'm good to go? Or select all Except: System Image(only) & Vendor options (both)?
Also, just so I can understand a bit better, "System" is the actual OOS? Meaning, if I restore Boot & Data on any OOS, all my apps and data will be as I never left, or we should always restore on the OOS that was current at the moment of the Backup (which I have always done in the past).
PS. I may just do the backup again, just to make sure SYSTEM & VENDOR are not there for good measure!

First off, I already posted everything you need in my last comment and that's what I usually do. Everything should be there and not like you need to pay or reply to get the extra stuff that you may need. No point in replying asking for more as I'll just be repeating myself over and over.
Just choose boot & data for TWRP backups for OOS specifically going forward and after you got your device from repair. System, vendor doesn't work in my experience and will crash your system. Only backup the .img variant which was stated by the dev (Mauronofrio) for TWRP for OP6/6T devices. Only backup system.img and vendor.img if u need to backup system+vendor, but YOU don't have to for OOS and I said this previously.
JUST DO A BACKUP OF EVERYTHING OTHER THAN SYSTEM AND VENDOR. YOU SHOULD ONLY BACKUP SYSTEM.IMG AND VENDOR.IMG NEVER SYSTEM OR VENDOR.
They never work and will increase the size of your backup and will take even longer to transfer to your storage device from your phone.
YES, to your new question. You should update/ be on the same OOS version as your TWRP backup before u restore data + boot. Restore OOS via fastboot or msm and update to get to the same version of OOS as your TWRP backup. YOU should only do this if your phone is in the wrong version of OOS as your backup after you've got it back from REPAIR.
ALWAYS BE ON THE SAME VERSION OF OOS AS YOUR TWRP BACKUP BEFORE YOU RESTORE YOUR TWRP BACKUP OF OOS!
Maybe take a copy of your wifi passwords, take a google backup in settings, take a copy of sms/call logs and contacts. Other stuff that you may not have stored just in case the TWRP backup fails, but it shouldn't. Good luck
This should be it and there isn't anything else that you'll need

YES, to your new question. You should update/ be on the same OOS version as your TWRP backup before u restore data + boot. Restore OOS via fastboot or msm and update to get to the same version of OOS as your TWRP backup. YOU should only do this if your phone is in the wrong version of OOS as your backup after you've got it back from REPAIR.
ALWAYS BE ON THE SAME VERSION OF OOS AS YOUR TWRP BACKUP BEFORE YOU RESTORE YOUR TWRP BACKUP OF OOS!
Maybe take a copy of your wifi passwords, take a google backup in settings, take a copy of sms/call logs and contacts. Other stuff that you may not have stored just in case the TWRP backup fails, but it shouldn't. Good luck
This should be it and there isn't anything else that you'll need

Thank you!!

Hey guys, for some reason I ended up on "Unmodified System Partitions", must have tapped the screen a few times in error while handling the phone I guess.
What should I do?
Unable to go back to TWRP main menu without selecting an option.
I am rooted, on stock OOS and not doing customs ROM at this time...
What should I do?
Select "Keep Read Only"? or Swipe to "Allow Modifications"?
thanking you guys in advance for you help & guidance!

Swipe to allow modifications. But it seems that your internal storage corrupted. Not sure what you did and how you got into this situation.
After you swiped to allow modifications... If the internal storage files are a messed up, try to switch slots and reboot recovery

Cool and at least that was a easy fix

Sorry, I'm a total noob, hopefully this is an easy question to answer. Is there any way that I can tell what version of OOS my TWRP Backup contains? I can't remember what version my phone was running when I did the TWRP backup and don't want to mess it up after I restore the phone from MSM. Thanks in advance for your help!

Well u posted this twice which isn't necessary and people will try and reply. But I'm not sure if there is a way to know and as long as u copied the whole TWRP folder for that backup, u should be fine restoring it with a newer version of TWRP. If it really matters to you, then maybe try and find the latest TWRP on the date you did the backup? I think just using a newer TWRP version should be fine

Should I use the same Gapps package I flashed during clean installing when updating custom rom?

U don't have to use the same gapps package. Using a updated one would be better. But, u only have to for ROMs that don't include gapps (vanilla builds) AND the Restore script doesn't show up during installation. Opengapps doesn't have that script but nikgapps does. Using dirty flash/updating a ROM should show the restore script and if it doesn't then just reboot to recovery and flash the updated or same gapps package. This can also be the same for updating the base/vendor (use method 3 in that section of the guide). I hope this helps

Thanks for your replay)))it's my first using vanilla rom(without Gapps), so I flashed nikigapps Omni package, and my question is: should I always use the same package, or I can go with core package for example?

U can... But it doesn't really matter as a updated package works fine and u only need to use it if the nikgapps restore script doesn't show up when updating the ROM or vendor/base (OOS underneath)

I want to CHANGE custom ROMs (havoc to Lineage OS a11 to a12) I have taken TWRP back up of boot+data+system.img+ vendor.img. once I flash the new a12 Lineage plus Nikapps core plus magisk. What steps to restore data? any response is appreciated in advance. Thank you.

[CLOSED] [No longer maintained] [RECOVERY] [11] [OFFICIAL] TeamWin Recovery Project (8T / Kebab) (2022-03-09)

Introduction:
Team Win Recovery Project or TWRP for short, is a custom recovery built with ease of use and customization in mind. We started from the ground up by taking AOSP recovery and loading it with the standard recovery options, then added a lot of our own features. It's a fully touch driven user interface , no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.
Key Features:
Touchscreen driven with real buttons and drag-to-scroll
XML-based GUI that allows full customization of the layout true theming!
Settings are saved to the sdcard and persist through reboots
Ability to choose which partitions to back up and which to restore
Ability to choose to compress backups now with pigz (multi-core processor support for faster compression times)
Onscreen keyboard
Easy selection of internal/external storage
In addition to the above new features, TWRP features a scripting engine that allows an app to send commands to the recovery for the recovery to perform during startup. We call this scripting engine OpenRecoveryScript. This engine will be put to use immediately in the GooManager app. GooManager will be able to install recoveries automatically for most supported devices. The app will also let you choose to install multiple zips from within Android, wipe, and run a backup.
We are looking for other talented developers, themers, and device maintainers if they are interested in helping with a free, open source project.
Source Code:
GitHub - https://github.com/TeamWin/android_bootable_recovery
Gerrit Instance - http://gerrit.twrp.me
If you have made your own TWRP build for an unsupported device, please let us know. We might add your build to the list of unofficial builds. Bear in mind that we are working hard to add more devices and we may add your device to our official build list later.
Hello, this is TWRP, for Oneplus 8T
Installation:
# To temporarily boot it
fastboot boot <twrp_file_name>.img
# Since 8T/9R has a separate recovery partition, you can flash the recovery with
fastboot flash recovery <twrp_file_name>.img
Updating to a newer build:
Simply flash the latest TWRP installer zip from TWRP
OR
Flash the img from TWRP/fastboot
FAQ/Know Bugs are given in post #2

FAQ and Known bugs of TWRP:
If you are planning to switch to a custom ROM, and are currently on OOS/H2OS, format /data, switch slot, reboot to TWRP and then sideload/flash the ROM + installer.
It's better to flash ROM + TWRP installer, if you want to keep your TWRP after flashing a ROM.
Don't format /data, after a flashing a ROM, before the first reboot.
It takes around 50s to actually boot into TWRP.
Ideal way to flash:
For OOS to Custom ROM - Format /data, switch slot, reboot to TWRP, sideload/flash ROM + installer, reboot to TWRP, flash Magisk/Gapps. Reboot to system.
For Custom to Custom ROM - Format /data. Flash ROM + installer, reboot to TWRP, flash Magisk/Gapps. Reboot to system.
For updating a custom ROM - Flash ROM + installer, reboot to TWRP, flash Magisk/Gapps. Reboot to system
For custom ROM to OOS - Format /data. Flash ROM + installer, reboot to TWRP, flash Magisk. Reboot to system.
PS: After formatting /data, until the first time the device is booted to system, the files you send to phone via MTP (USB) will be at /data/media, not at /sdcard
PS2: If, for some reason, you cannot send files to phone after formatting /data and rebooting to TWRP, press vol +, vol - and power button simultaneously.
PS3: Factory reset WILL NOT wipe internal storage.

Steps for backing up and restoring data in TWRP (Huge thanks to @BillGoss )
TL;DR for data backup on custom ROMs:
Backup /data (copy the backup folder to PC if you will format /data).
Flash the ROM and boot it once to system.
Restore /data (copy the backup folder back from PC if you formatted in step 1) and boot into system.
If you find any issues like missing navigation bar or blank screen or something, just do a normal reboot again to system.
System Backup and Restore
The "system" partitions on the OnePlus 8T are:
Boot
DTBO
Super which contains the logical system, system_ext, odm, product, and vendor partitions
Just backup and restore these partitions.
Do NOT backup/restore any of the logical partitions individually.
Data Backup
Make sure USB debugging is enabled
You do NOT need to remove your password
In TWRP
Backup: Select only the Data partition.
Reboot System
Restore
Remove the current password before starting the restore process by Settings>Security & Lock Screen>Screen lock: Select Swipe (if prompted tap on "Yes, remove")
If you don't do this, the system will not reboot properly after restoring.
This will also remove your fingerprint data and your lockscreen (encryption) password (you won't be prompted for a password in TWRP or when you restart the system)
In TWRP
Wipe>Factory Reset
Reboot System (this will rebuild the data partition)
Back in TWRP
Restore: Select the backup you want to restore
Remove the SIM card. If you don't do this the system won't boot properly.
Reboot system, making sure the phone is not connected to a PC
Notes:
At this point the phone will take longer than usual to boot - that's normal
You will be presented with a blank screen
Connect the phone to a PC. You should be able to see the phone using adb devices
Disconnect the phone from the PC
Hold the Power button down and select Restart
In System
Settings>Security & Lock Screen>Screen lock: set your password
Insert the SIM card
Note: Your fingerprints will have been restored because the backup was taken with the password set.

Thanks for it!
Gonna try it!

Amazing! My OnePlus 8T is arriving tomorrow. Perfect timing for TWRP, thanks a lot for the detailed instructions as I am going to need it.

I was flashing this twrp with the previous test_kebab twrp as flash .img. Choosing recovery partition and was thicking "install to both slots".
So far works good.

Bro, I'm happy for you. Great job.

@theincognito Though I am a fastboot flash guy at this point (honestly forgot how to even use TWRP after all this time), I appreciate all the work and time you (and apop) put in for this project. It's definitely going to make this device appeal to more Android enthusiasts as most are used to and prefer TWRP for flashing I've noticed. And that will lead to more development (hopefully) for the device. That seems to have been the case with previous devices I've owned that had TWRP available, but also had the fastboot method available.
Anyway, I have been up for like 32 hours, so if what I've said doesn't make much sense, sorry.
Thanks @theincognito for all your work and time, and I hope this brings more to the 8t community. Good job!

He has this. Again, great job. Glad folks now have a thread to come to for proper support

Yep, works fine.
You can also flash the zip in the Magisk app, manually from the modules page.

Booted on 9R but unable to decrypt data, after switching to 9R compatible kernel everything is working fine.
Nice job bro.

@YumeMichi Thanks a lot for this. I shall make a build with the AOSPA kernel and test on 8T. Should I release it here then, or do you wanna release for 9R?
