(SCRIPT) Disable force encryption.

Hi all,
I'm currently not encrypted and prefer to keep it that way, I don't like entering passwords everytime I go to TWRP and I prefer the old school android system where encryption was a choice, not a mandatory decision made for you.
So when I install a ROM I run a few commands prior to installation to avoid forced encryption, unless it has an option within aroma to disable force encryption which most don't
Thanks to @j to the 4n for help with this, legend
Anyway if you'd like to install a ROM like lineage or aosp or resurrection remix etc and remain not encrypted? Keep reading.
*Note: if you're encrypted prior to doing this then stop, this is for people who've chosen to disable force encryption already but would like to retain it after installing aosp / lineage ROMs.
However if you'd like to remove encryption you'll need to format data via TWRP, not a wipe! Format.
Make sure you back up prior to doing this as it will format data, best to have the ROM on your SD card too so you don't end up with no OS.
If you've done the above or you already have a ROM installed without encryption, then you should be good to go.
------------------------------------------------------------------------------------------------
Just before youre about to install a ROM, let's say resurrection remix ( tested )
Make sure your phone is in TWRP and you're connected to your PC then just before you're about to click install, open up a command prompt on your PC then from ADB shell send the following commands to the device from your PC..
For Magisk:
echo "KEEPFORCEENCRYPT=false" >> /cache/.magisk
If the rom uses SuperSU, send the following commands.
echo "KEEPFORCEENCRYPT=false" >> /data/.supersu
echo "KEEPFORCEENCRYPT=false" >> /cache/.supersu
Then install your rom as normal.
Obviously for ROMs like viper your don't need to do this as there is an option within aroma, but for the likes of RR or lineage this will mean your phone will not encrypt on boot.
Should work for all ROMs but I've not tested this on all of them so if it goes wrong then it's not on me, this worked perfectly for me on RR coming from viper whilst not encrypted.
*Note: if you're not sure what root method your ROM uses then simply send all three commands and you should be good to go.
By using these you're not going to find yourself in TWRP being asked for a password you don't have as your device has been encrypted, I've lost data myself this way and it's extremely annoying.
:good:
If I can ask if anyone tries this and it works, would you mind replying with what it worked on so I can update the OP.
Cheers.
PS: if you're not sure what this is or have any questions, please ask away

Anyway to do this from the device for when your not near a PC?

Yes i believe it is, would need to write up a script which is ran prior to installing the rom, i've not got around to doing it yet.
Strictly speaking this should be an option with all roms, it's not exactly a lot of work is it?

Works pretty well on Stock ROM.
Just RUU'd, and before rebooting went into download mode, flashed Recovery, flashed SuperSU, used this Command. and boom.
Multirom works.

I used to have a one plus 3 and for some time before everyone used forced decryption the good ol friends from kali net hunter made a forced decryption zip, I will put a link down below, but listen when I say this, every time you flash a new boot .Img, or rom on the htc 10 you need to flash this if you want to stay decrypted. Its ok if you flash multiple times.
The file you want is, "no verity force encrypt".
I've used it on almost every aosp and stock based rom I've flashed also used on many custom kernels to, it still stayed decrypted.

Yea it's used on the OnePlus 5 too. I wrote this prior to knowing of its existence and because the likes of lineage and other ROMs just assume you know, no warning.
Losing data is not fun.

Yeah it pisses me off. But at least with this handy zip you can flash it anyway and have some mental relief that you stay decrypted.

i've flashed the v 5.1 got greeted by a "Encrypting" Wait while your phone is being encrypted. Time remaining 01:50 Screen.
Guess that does not work on PureFusion OS ROM / HTC 10

Sorry I hadn't tested with all ROMs, not even sure Pure Fusion was even available when I had my HTC 10.
Stick to the script, it's quick, easy and works, you can try a zip but unless someone has gone before you you're potentially walking into a bad time.

Jep.... the zip doesn't seem to work no matter what. Not even on Stock ROM. Prolly not compatible with HTC10.
These 2 Command lines though do work perfectly fine on PureFusion OS... simply install ROM, install SU, enter 2 lines. Done.

That's absolutely fine. Because this thread isn't about the zip..I have nothing to do with that, so in regards to the zip you flash it at your own risk.

Though i do agree with him that having a .zip and not needing a Computer every time would be pretty usefull.
Does anyone know how to create TWRP flashable zips that includes only this 2 commands?

Hello I tied this for RR rom but I got this message in the cmd, am i doing something wrong?
edit i found my fault I had to adb shell

I know it's been about a year, since somebody posted, but: if anbyone else like me stumbles across this thread, have a look at: https://www.didgeridoohan.com/magisk/MagiskInstallationIssues
It gives you even more information how to enable or disable encryption or dm-verity while usinf magisk.
Btw. you can use the terminal in twrp also, see link.

Can I use the built-in twrp terminal for echo-ing rather than using adb shell ?

Ofcourse,cause echo command is available everywhere.just make sure you install the magisk/supersu first before running the command

hi,
If I format /data, then the encryption is gone and LOS can be installed where backup with TWRP work?

Rooting process is taking too much time ?

Hello xda. I'm making this thread in order to know if it's normal that super su is taking so much time to install. My Moto Z play is stuck on this screen since 15 minutes.
Beforehand i unlocked the bootloader and flashed the f2fs kernel. On previous phones it did'nt took this much so I don't understand. Anyone can help me ?
EDIT = Impatience is growing... How can I do to at least reboot the phone without damage ? It's brand new so I don't have to worry about losing any data. Why is it so hard to root a motorola anyway ?

try with MagiskSu, SuperSu is not working correctly in this device because of the Nougat security, if don't flash anything, maybe you should take your time and read this post https://forum.xda-developers.com/moto-z-play/how-to/guide-magisk-official-version-including-t3577875

It is not hard to root Motorola. It is hard to root any device where the /data partition is using f2fs filesystem.
SuperSU in general should work fine after f2fs fix is installed, but I like Magisk more. Not changing system partition when changing system (only do virtual changes using bind) is a very nice idea and the implementation is very good. Only thing that is missing for me is to prevent changes to system (forbid or virtualize "mount -o rw,remount /system" command).
If you want to stay with SuperSU, just use a current one. The 2.79SR3 from January 2017 is the first version that detected need of systemless install on Motorola. All later versions should work also or be improved. There may be some error corrected since then.

Lineage OS 15.0 Dev Thread [DISCUSSION]

Figured we should have a thread set up for discussion, has anyone started work on this? Maybe we should get a hangouts group started.

When does the development starts?
I don't know the procedure of ROM development. Are devs waiting for the oreo update from HTC?

Some devs already work on Oreo aosp, but it's not that easy to get it working on the 10 so that everything works. Maybe even stock will be earlier here than custom Roms like aosp and los

You can't start a "Dev thread" if you aren't a dev on the project; you can only start a "Nag thread".

Sorry for unqualified question. I know the new site but I don't know where to find dev threads. If you can help me I'll be glad.

My question is why do some older phones have LOS 15.0 and we don't yet. You'd assume the newer phones get priority. My old HTC M8 has a fully functional LOS 15.

That device still has an active developer working on it. crpalmer, the user who brought 14.X to HTC 10 seems to have moved on to newer devices.

hope it will have LOS15.1

Even though Raymon left development does this mean there are no los 15 for us?

As already stated by fagyi, once he solves all bugs on aosip 8.1 he will build los.

15.1 Running flawless albeit hot sometimes!
Ladies and Gentleman,
I have been lately at the lack of instruction that some of the devs have in their OP in regards to the kernel challenges with running back and forth between nougat and oreo. All I want for my recently required and gently used HTC 10 was a simple and pure rom that I can theme and run unhindered of bloat and unneccesary tweaks without having to gut the rom with titanium backup. With that said, in my constant frustration over the past two weeks I have been able to get Lineage os 15.1 running flawlessly on my device as of yesterday with everything working including the camera and tethering. The speaker volume is a bit low, but I can live with that.
To run this as with the other 8.0 rom you have to be on nougat kernel. IF you are already running Oreo- stock or otherwise, you will have to downgrade your kernel being s-off. Generally I don't pay for sunshine but since i got a great deal on this used phone i coughed up the $25 bucks to fix my phone after deciding I wanted to run modified oreo without having to read 1100 pages of posts.
Personally I have Sprint as a provider so I used a combination of OMJs kernel flashing instructions

Now I tested this rom by flashing multiple times and I could not get any version of gapps to work but then i discovered a work around that will help. But before I get there let me explain everything I did. Some steps may be unnecessary depending on where you are coming from but i think nougat kernel is a must. I did not ruu after kernel flash.
1. Flash kernel using adb.
2. Boot straight into bootloader then Wipe and then fix persist per wonders never ceases post.
I had issues with going back to nougat kernel and had to type these instructions in the twrp terminal to get my persist back:
To fix : failed to mount '/persist' (invalid argument)
Type this in twrp terminal:
make_ext4fs /dev/block/bootdevice/by-name/persist
MAKE SURE YOU DO CLEAN WIPE all internal and format data. Fix ext4 after.
3. Resend twrp from adb.
4. Flash lineage Rom
5. Flash Magisk
6. Boot to Rom and install from Magisk G-apps systemless framework
This will not show up as being installed in magisk anymore after you install gapps. Gapps overwrites it somehow. But if you try to install gapps by itself, it will fail and crash when you boot to the rom.
7. Reboot to twrp and flash nano gapps.
8. clear cache, format data
9. profit!
Finger print scanner, Camera and everything is working. have not found any issues yet. Since I am kinda excited at getting back to LOS because i couldn't get it for my Bolt, i wanted to share with everyone else that fagyi's work is payoff.

I'm using that ROM build of 15.1 on my HTC 10 (Android 8.1), and it works pretty good actually. besides a few minor issues.
Unlocked Bootloader from HTCDev, Running latest TWRP Recovery, S-On (for me at least was not needed to turn this off), Latest Magisk (which seems to pass the Safetynet check) / Busybox.
I changed the Kernel afterwards to "kernel_htc_pme_aosp_tabp0le_eas_4.02-O" (from tabp0le) because it has the "performance" cpu governor that i can enable using Kernel Adiutor.
The bugs i encountered so far :
- Camera apps open slowly, except for "Open Camera" , not a big issue.
- HTC Sense Launcher doesn't seem to work, just get the famous (app has stopped) message, but maybe it's a conflict with my GAPPS installation
- Only 1 speaker works, HTC10 has Boomsound with 2 speakers on stock rom, 1 is a treble speaker, the other one is kinda like a small subwoofer for the low frequencies.
Is there any soundmod that would enable both speakers again?

There is not any mod to do that. But the dev of this ROM is working on getting the bottom speaker working.

I just saw that a new build-version is released for HTC10.

2.flashed stock boot.img
3. Flashed the magisk.zip
4.got an error saying it failed to install magisk.zip
But whenever I try to reboot to system (I've tried reinstalling SuperSU and without reinstalling as well) I got a bootloop Everytime can someone instruct me or tell me what I'm doing wrong?

In Short. Currently for our device to have magisk, you need to use the boot image that @joemossjr and @Uzephi developed with Magisk support. Then install the magisk app. No zip install.
Refer to Joe's thread for the boot image at this link

I would suggest updating to November. I have a rooted magisk image, but you need to flash the decryption zip to get it to boot. If you update to November, I am going to release a flash-all type zip sometime today (after I fiddle with getting 4.4.107 upstream done) and working on a Google Pixel 2 skinned ROM for us here shortly with oem bloat completely removed

You using stock kernel? To get crypto changes in 4.4.101-103 added, it breaks encryption on our phones and will cause a boot loop due to Motorola's dirty code. Hopefully when Oreo ROM drops (since Google is kinda telling oems to stay upstreamed) it will fix those issues in our stock ROMs.

Hard to say. Those of us that have tried hard bricked the device. Not readable via USB and wouldn't boot anything after the flash.

To build off what Uzephi said. It's not that rom's wont be capable. It's just working with new things that are being implemented and changed until something starts going right. The jump to Nougat changed a lot of things with security and the switch to Oreo is changing even more that Google is wanting to push for android that inadvertently also affect security and compatibility.
This is speculation, but since they introduced Kotlin, I feel like they are trying to alter everything over the long run to become more streamline and compatible around it. Especially given they can control the progress of the script language to help them better. Which will really show true or false come mid next year.
We are lucky that Motorola sticks to a super close to stock experience because it's one less issue to deal with when playing with the new code and functions to try to get things to work. I'm really optimistic on this stuff because I like doing things that people think can't be done. So I believe that there will for sure be more customization and capabilities as we figure things out. Just takes time and effort. We worked for months and months on the S8 where people said impossible, and ended up getting it. So i have faith on this.

Motorola already admitted the Z series will not be a part of Project treble meaning we need to try different vendor files to see if builds work. Sadly the ones used for the Z1 and wahoo mixed together cause the phone to go haywire and brick itself.

And I understand that this means lack of simplicity in developing custom rom's. But it doesn't mean incapability. From what I understand as well, that treble can be implemented at a later date even though it will not be included with the initial Oreo update. You are working on a pixel rom conversion if I am correct right? Because I might have an idea...
But treble is still def exciting to think about being able to have one rom work on many different phones without modification. I honestly haven't divulged too far into it, but what are the odds of tearing apart the code and possible making support for it ourselves? I'm all for ridiculously long spans of working towards absurd goals hah

Unless Motorola can repartition the phone, Treble won't come out, it needs a vendor partition. I can say at least on my Sprint phone the OEM block is about 1.5 GB when there is only about 200 MB of data on it, so they can splice that to save user data. Only other way is to repartition /system or /userdata for the space needed for the new partition.
Yes, I am doing a pixel conversion ROM. Tried just booting the pixel /system and it didn't work. I am taking assets from the Tamien and putting them into our November update using SuperR.

I know there are few devs out there working on making it work on non treble phones. Repartitioning and adding a vendor partiion wouldn't be the issue with making it work. Rather trying to get the vendor source for drivers to add to it, and if they need to be reworked to add support. I've been off for a few months with health issues so I'm still getting back into things with oreo, but that seems to be the biggest issue at the moment that I could find.
When my health is back to 100 percent within a couple weeks I will dive into work with you and aid in any way possible for this. To me, trying to get driver source and make it work sounds fun. but we are far off topic now for this post so I'll leave this here haha.

[GUIDE][A10/A11] Flashing and booting GSI on Galaxy Tab S7+

Code:
/*
* Your warranty is now void.
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/
This is tested on my SM-T976B, but I think the same should work on other models as well.
1. WARNING AND DISCLAIMER
Just unlocking the bootloader will not trip the warranty bit yet, so you can still go back at this point.
The warranty bit will be tripped (0x1) as soon as you actually try flashing something unofficial via Odin. YOU HAVE BEEN WARNED.
Make sure you back up all the important files in your internal storage, as you need to disable encryption with Multi-Disabler in order to let TWRP access the data partition, which would require you to format the data partition (wiping everything in the process). Additionally, keep a few nandroid backups with you so you can recover yourself in case something goes wrong.
2. Requirements
- Bootloader unlocked
- ianmacd's TWRP
- Neutralized vbmeta*
- (Optional**) vendor.img from Android 10 stock FW (I used ATK3, but any A10 vendor should do)
- Multi-Disabler
* An empty vbmeta is not recommended. You need to patch the vbmeta of the stock FW you're currently on.
** UPDATE (2022-08-29): It seems Magisk now works with recent A11 GSIs using A11 vendor, so there's no explicit need to flash A10 vendor in the following tutorial steps, unless you run into issues. Thanks to @AnonVendetta for testing and confirming. Using a more recent version of Magisk is recommended.
3. Flashing
Since this device uses dynamic partitions. Flashing system images is not as straightforward as before but not impossible.
azteria2000's GSI Flasher provided a good example on how to use dd/simg2img to flash dynamic partitions using just recovery. This is extremely helpful, as TWRP currently doesn't support fastbootd, which would make flashing even easier.
(1). Extracting Android 10 vendor.img (Optional, unless you have issues with your current vendor)
While you can boot recent GSIs with Android 11 vendor, Magisk currently doesn't work with it. Android 10 vendor is required for Magisk to work properly.
The Android 10 vendor can be extracted from the factory image's super.img. You need to unsparse the image using simg2img then use lpunpack to extract it, and you'll obtain the vendor.img.
(2). Flashing GSI and (Optional) Android 10 vendor.img
The entire flashing process can be done from TWRP.
NOTE 1 (UPDATE 2022-08-29): Flashing A10 vendor is no longer necessary now, unless you have issues.
NOTE 2: At present, Multi-Disabler expects /system_root to be mountable r/w, which cannot be done with a non-vndklite GSI. As such, if you're about to flash /vendor at this step, use a vndklite GSI, or if you're coming from stock, flash Multi-Disabler before actually flashing GSI (a reboot is needed after flashing /vendor to make it accessible).
The corresponding block devices for system and vendor are as follows:
Code:
/dev/block/dm-0 - system
/dev/block/dm-1 - vendor
First set the block devices to r/w so you can flash images.
Code:
# blockdev --setrw /dev/block/dm-0
# blockdev --setrw /dev/block/dm-1
Now actually flash the images with dd. Change the "if" parts to point to where the GSI system image and Android 10 vendor image are.
Code:
# dd if=<GSI image here> of=/dev/block/dm-0 bs=1m
# dd if=<vendor image here> of=/dev/block/dm-1 bs=1m
In rare cases that the GSI image you're about to flash is sparsed, run the following command instead of dd. You need to point to your sparsed GSI image here.
The vendor.img you obtain from super.img is not sparsed and can be flashed directly using the dd command above.
Code:
# simg2img <sparsed GSI image here> /dev/block/dm-0
If nothing goes wrong, you've flashed the GSI as well as Android 10 vendor.
Android 10 vendor flashed this way will work even if you have upgraded past BUC1 (which blocked the downgrade to Android 10).
It's advised to reboot recovery before trying to access system and vendor, to avoid potential issues.
NOTE: If you flashed vendor in this step, DO NOT REBOOT TO SYSTEM JUST YET.
(3). Flashing Multi-Disabler
You need to flash Multi-Disabler to disable encryption of internal storage so TWRP could access it.
If you flashed the vendor.img when flashing GSI, you MUST flash Multi-Disabler again if you have already disabled encryption with it before.
After flashing Multi-Disabler, you can now try booting to see if the GSI of your choice works.
4. Important Notes
(1). Neutralizing Software (Platform) Watchdog
There's a software (platform) watchdog that by default doesn't get fed while running GSI, causing system to reboot about 100 seconds after boot due to "platform watchdog bite". See this issue and this issue for details.
It's possible to disable this watchdog after boot, by executing the following command using a root shell.
Code:
# echo 'V' > /dev/watchdog
You need to look for a way to execute the command above at boot to automatically disable the problematic watchdog so the GSI can function normally. There are several ways to do this, like putting the command into a Magisk module's service.sh so it gets executed when the Magisk module loads.
EDIT: I've filed an issue regarding the matter here. After some testing, it seems /dev/watchdog0 is the real culprit for our device. Disabling either /dev/watchdog or /dev/watchdog0 will work this around.
UPDATE (2021-09-11): I can confirm that DragKernel is not affected by this issue. The offending watchdog is not present and the system won't reboot after 100 seconds.
UPDATE (2022-08-29): The watchdog is mainly an issue if you use A10 vendor. You may not have issues with that watchdog if using A11 vendor but it's still recommended to get it disabled.
(2). Uncertified Device
Since phh-AOSP v303 and onwards, the device is considered uncertified which will prevent you from logging in to your Google account.
Manually registering the device is required for using Google Play Services, but for some reasons that didn't work for me, so I recommend using NanoDroid with microG if applicable (requires Magisk).
(3). Offline Charging Icon
With some GSIs, when powered off, plugging in the charger would make the tablet enter a screen with a white charging battery icon in the middle, that I couldn't easily get out of by pressing POWER button alone. Although I did manage to get out of that screen and boot to the system, I don't really know which button combination is required, and how long I should be holding them. So for now, charging while powered off is not advised...
(4). Potential soft bricks with Securize
UPDATE (2022-08-29): Should have pointed this out earlier that if you attempt to Securize on official phh-AOSP, the device will softbrick. Additionally, merely removing phh-SU is enough to cause the softbrick (thanks to AnonVendetta again for confirming).
While the cause is uncertain, it's quite likely that the tablet cannot work if not using any form of root (be it phh-SU or Magisk) due to Samsung's security mechanisms getting in the way.
5. Working Stuffs
- 120 fps working (by forcing FPS using Phh-Treble Settings).
- Wi-Fi and Bluetooth work fine.
- S-Pen works as a pointer device.
- Alternate Audio Policies (from Phh-Treble Settings) is needed to get audio out through USB Type-C.
- Front and rear camera appears working.
6. Not Working Stuffs
- MTP does not appear to work properly for some reasons. You'll need ADB for transferring files.
- USB Type-C audio adapters may or may not work depending on GSI, Kernel or maybe other aspects.
- Bluetooth audio currently has issues that cause the system to freeze.
7. Untested Stuffs
- Haven't tested telephony-related stuffs as I'm not using a SIM card on the tablet yet.
- Haven't tested fingerprint sensors as I'm not using it.
There are still some functionalities I haven't tested yet, but anyone is free to test if you want to use a GSI.
Special thanks to: ianmacd, phhusson, Bushcat, Vntnox, azteria2000, dron39 and many more...

I finally got this working on my SM-T970. Though I had some troubles getting it working by following your instructions exactly, it would still boot loop even after neutralizing vbmeta.img (perhaps I changed the wrong offset?). Though for some reason flashing magisk made it boot perfectly? I assume Magisk disables AVB entirely or something. Thank you for this guide, may this tablet live a long life thanks to treble!

i also got SM-T970 please help me to get back to android 10... Most of the game which play crashes in the middle for android 11 ... Can you please help me to do what you did ... i am new to this custom ROMs and flashing so help me..

As I know, you can't. All android 10 bootloaders are XXU1 - if you upgraded to XXU2 then nothing can be done.

Sorry, didn't notice there were new posts in my actual thread...
While you certainly can't flash XXU1 firmware via Odin once you upgraded to XXU2, you can follow the instructions to use dd in TWRP to flash the logical partitions. This is how I used to flash vendor image extracted from Android 10 FW, as due to SELinux policy issues, Android 11 vendor does not work well with GSIs on Samsung Qualcomm devices in general. Magisk won't work, and the tablet would semi-brick if you attempt to use Securize from Phh-Treble settings.
While I mostly use Android 11 GSIs, the same should work with Android 10 GSIs of your choice, but I haven't tested, as most A10 GSIs are no longer maintained. GSI image of your choice (/system) and A10 vendor (/vendor) are all you need, as GSIs do not care about /odm and /product so it's safe to leave them as-is.
A WARNING: I DO NOT recommend flashing A10 stock FW using this method as you're literally violating the rollback protection which has the risk of causing A HARD BRICK!!! Similar cases have happened on other devices of other vendors before.
ONE MORE WARNING: Due to the ongoing case of Samsung disabling cameras on Z Fold 3, I seriously advise against upgrading the device any further, especially in case a XXU3 firmware comes out in the future, as there are potential signs that such crippling behavior might spread to existing devices.

@LSS4181 thanks dor for deep explanation, but I'm afraid my level is not high enough to understand all of this. I am also tempted to try gsi but not want to risk lot...
So, can it be installed over stock android 11, new bootloader XXU2?
Thanks

I can't guarantee A10 GSI will work on such environment, but GSIs probably won't have issues with rollback protections. It's just stock ROM might have something that would do dirty stuffs in case such violation happens so I personally would not recommend such use case.
However, A11 GSIs will certainly work fine, just that with A10 vendor you need to use DragKernel as the stock one has a watchdog that'll reboot the system after 100 seconds.

@LSS4181 - thank you for the guide, I've had a T970 for nearly 1 year now, always wanted to run a custom rom on it!
I've tried your guide twice now, but it results in failures for me.
I've unlocked the bootloader, flashed TWRP (twrp-gts7xl-3.5.0_10-A11_3_ianmacd.img), running ATK3.
Not sure if TWRP for Android 11 and ATK3 being Android 10 makes a difference?
I extracted a vbmeta.img.lz4 from the ATK3 pack online, decompressed it to get the vbmeta.img, and wrote 0x03 to decimal offset 123.
(Tried to follow the instructions exactly)
I think it's the flashing/dd part.
After I dd the gsi img to dm-0, I can not reflash the multidisabler anymore. It tells me something like:
"Failed to mount '/system_root' (Invalid argument)"
Then, I can't even mount 'system' in TWRP, the checkbox is unselectable.
To get back to a working state, I have reflashed the stock rom (ATK3).
The GSI I tried to use was: system-roar-arm64-ab-vanilla.img.xz - from AOSP 11.0 v313
Is this the correct version to use (A, A/B etc?)
And how can I tell if the image file is sparsed or not?
Any input is appreciated, thank you!

Uh... I should have mentioned earlier. Multi-Disabler expects /system_root to be mountable r/w, which cannot be done with a non-vndklite GSI.
As such, to disable encryption, you'll initially need to flash a vndklite GSI, or simply just do that before you actually flash the GSI (stock ROM can be mounted r/w). As Multi-Disabler is only needed once per /vendor flash, you'll be able to use non-vndklite GSI afterwards.
EDIT: If you are experienced in modifying recovery zips, you can edit the Multi-Disabler install script and comment out the parts actually involving /system or /system_root.
EDIT 2: I just realized this... I recall that phh AOSP GSI is sparsed. You need to use simg2img command instead of dd to flash it.

@LSS4181 - thank you for the reply.
I am not sure if the images I was trying to us were sparsed or not.
Since you mentioned vndklite images, I tried those - `simg2img` told me that the hash/magic was not valid, so at least these ones are not sparsed.
But good idea to attempt to use `simg2img` if you are not sure about an image, it doesn't hurt to try.
I flashed phh's v313 ab vndklite image, my device was stuck on the samsung boot screen for about 10 minutes (the screen with "your device is unlocked" etc...) I then held some buttons to force reboot/power down. I powered back on and I finally saw the rom booting.
Vanilla AOSP was a bit boring, so flashed LOS 18.x (vndklite again) and that is great. Dark mode can be made BLACK which I really appreciate.
No issues with the watchdog/no reboot after 100 seconds.
I did try to install microg... tried to install (adb push) to /system/priv-data but must have done something wrong.
It gave me bootloops, tried to reflash the gsi twice but didn't seem to change anything...
I ended up reflashing stock again, repeated the whole process (apart from microg!) and my system is up working again.
I should go and ask on the lineage os gsi thread for advice about microg.
Thanks again for the guide.

That's exactly what I ended up doing.
Originally I wanted to avoid the 'newer' style, using Magisk etc, it seems more complicated than just using a rom that is already rooted. For my use case of this device, I don't care about safetynet etc, don't care about keeping system untouched etc.
BUT! Flashing Magisk was so easy, no need to patch any images... I simply flashed the latest version of the Magisk apk via TWRP.
On restart, Magisk app wanted to finish the install itself... but failed? So I simply installed the same apk myself, and it's been working perfectly

Thank you @LSS4181 for the exquisitely detailed instructions! I think have enough experience with this stuff to be succesful, but have not yet bought this tablet to try it (currently using a rooted, debloated S6).
Questions:
Which vendor does it ship with? ATK3? I wouldn't do any upgrades when I got it, but would immediately start flashing.
Has anyone succesfully used XPrivacyLua (XPL) on this? I currently use XPL Pro, and I know that it depends on a working EdXposed (or Lsposed, which I've never used) which requires a working Magisk. From reading this thread, the Magisk part seems Okay, but what about Ed/L Xposed?
Thanks again.

I got my tablet early so it was on an earlier version than ATK3.
If your device ships with BUBB or before, you should be able to downgrade directly if you know how to use Odin.
Flashing ATK3 (or earlier) vendor via dd from TWRP is only needed if your device is on BUC1 or later, as from that version onwards SW REV has been incremented so you can't downgrade via Odin anymore.

Thanks again for the detailed response. The info you've shared gives me confidence. Now I just need to convince myself that I 'need' to buy it.

@LSS4181: I've been running the stock Android 11 firmware since I bought the Tab S7+ SM-T970, about halfway into this year. Mine shipped with a version 2 bootloader, so there is no possibility of running stock 10 for me.
Then I saw your note about Bluetooth earbuds not working. This would be a big deal for me on a GSI. I don't want to use a USB C headphone jack adapter, since it would prevent charging while using them. And it would wear out the charging port by constantly inserting/removing.
What BT earbuds do you use? Does it happen on all GSIs that you've tried? I saw your recent issue on GitHub, and noticed that no one else has commented.
GApps is another big deal for me, a must have. I used to use MicroG on my daily driver devices, but stopped using it about a year ago due to issues that I was unable to find solutions for.
Can you elaborate a bit more on how to modify vbmeta and what to change? I'm not particularly skilled with the usage of hex editors, so not sure how to proceed here or what to edit.
I know there will probably be issues inherent to running to a GSI, but I'd like to change things up a bit and experiment. If I don't like what I see, I can always return to stock rooted. I'm not a big fan of stock firmwares, but so far it has been very stable for me. However, if I can get a custom ROM like AOSP, RR, LOS, etc running reliably, then I'd definitely switch. There are no features on stock besides Dex and Secure Folder, that are compelling enough to me me stay on it.

I'm not a big fan of stock firmwares, but so far it has been very stable for me. However, if I can get a custom ROM like AOSP, RR, LOS, etc running reliably, then I'd definitely switch. There are no features on stock besides Dex and Secure Folder, that are compelling enough to me me stay on it.

Bluetooth audio works if you disable the a2dp hardware offload in the phh treble app

@LSS4181: I've been running the stock Android 11 firmware since I bought the Tab S7+ SM-T970, about halfway into this year. Mine shipped with a version 2 bootloader, so there is no possibility of running stock 10 for me.
Then I saw your note about Bluetooth earbuds not working. This would be a big deal for me on a GSI. I don't want to use a USB C headphone jack adapter, since it would prevent charging while using them. And it would wear out the charging port by constantly inserting/removing.
What BT earbuds do you use? Does it happen on all GSIs that you've tried? I saw your recent issue on GitHub, and noticed that no one else has commented.
GApps is another big deal for me, a must have. I used to use MicroG on my daily driver devices, but stopped using it about a year ago due to issues that I was unable to find solutions for.

Don't know if audio issues might be caused by using a different kernel (as I've switched to using DragKernel for this tablet). I don't recommend using stock kernel, though, due to a nasty 100-second watchdog that you need to manually disable after system startup (DragKernel has that removed from config).
I recall it's now possible to patch vbmeta using Magisk now. Simply provide the vbmeta of your FW version to Magisk and it'll patch it for you. I haven't tried, though, as I always do this by hand with a hex editor (it's just to change a single byte, which the recent Magisk versions would do).
Back then I couldn't get the device certified so I switched to microG which is working well. I recommend using NanoDroid as it comes with a modded Play Store which allows you to purchase apps as well as IAPs. The modded Play Store still works, despite being quite dated.
I don't really have anything blocking me from using microG now. If you need real GApps and know about the workflow for uncertified devices, you may try flashing a bgN flavor GSI as opposed to bvN (g means the GSI ships with GApps).
