All this talk of Android 13 and Lineage 20.

Has anyone managed to breathe deeply and clear their mind and meditate on the fact that Android 12 and Lineage 19x are a retrograde step from Android 11 Lineage 18x ?

For my money I would have preferred that Android 12 never saw the light of day. Bad interface. Bad battery. No actual benefits.

And if Android 13 is more of the same, then Thanks but No Thanks.

I can hear the clarion call already from the We Must Have Updates brigade -

"Update or we will withhold all security updates, and might even hound you to the ends of the Earth".

To the right-thinking brethren amongst us, let your united call be a sane orison -

"Progress, not Regress. Enough Already".

Is anyone else finding that the keyboard case doesn't work anymore? Not a Bluetooth one, the Samsung one with the pins I thought my keyboard might have broken so Igor another, but it doesn't work either.

Is there some new setting I'm missing to enable it?
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] frauhottelmann:
Still works for me. But the connection with the pins has always been spotty for me.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] denisovich:
My SafetyNet works great.

Magisk 25.2 Zygisk enabled

Universal SafetyNet Fix 2.2.1

MagiskHide Props Config 6.1.2 v137

Flame Gapps 220920

LineageOS 18.1 20220425 nightly

The difference is the Gapps and the Lineage version. I will not be changing either of mine any time soon.

The idea that A12, or even A13 heaven forfend, are a step forward is utter nonsense.

By all means go with A12/13 provided you don't need proper working GPS, Wifi, SafetyNet, fingerprint, and a decent battery life, and anything else from the MOUNTAINS of bug reports.

This is not a criticism of @LuK1337 's ability. They have shown themselves to be very decent devs over the years. THis is about MASS HYSTERIA and following the lemming pack over the cliff edge.

Low battery consumption is important for me. I want to use my "new" tablet for internet, online banking and mails. So should I better choose LOS18 and not LOS19?
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] denisovich:
You could always try both and see which is best for you.

My preference is very clear, but your experience may be different.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] OhioYJ:
I pass.

I checked with this. (YASNAC - SafetyNet Checker)

Currently running:

Lineage 19.1 31 Oct (I need to update, I'll do that here in a moment)

vvb2060's build of Magisk (Nov1 build), however the official builds should work fine as well. vvb2060 just typically builds more often.

MagiskHideProps 6.1.2

Safety Net Fix 2.3.1

I do also have busybox installed, but that shouldn't be changing anything.

I'm using MindTheGapps. (not microG, however that also shouldn't change anything either)
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] OhioYJ:
On my tablet I didn't really notice a difference. On my phone, I would say the battery life was better on LOS18. However that would not make me go back to an OS that's not updated anymore.

On all my tablets I use NapTime (GooglePlay Link) to turn wifi, BT, GPS, etc off when the screen goes off. It makes a huge difference in battery life. It returns my settings when the screen turns back on. However it means all my tablets generally can sit for at least a week and not be dead when I pick them up.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] nostupidthing:
I cannot pass safety net but I don't have magisk installed is that normal?

It worked with TWRP. Any recommendation if I should change to the LineageOS recovery?
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] LuK1337:
Up to you, but FYI the recovery you sideloaded in earlier was Samsung stock ROM recovery rather than LineageOS one.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] Cepasaccus:
I tried to odin the recovery that came with the nightly. Maybe I failed and didn't notice it? I attached a screen photo of how it looked.

I suppose both recoveries have enough features for me. I want that recovery, which makes the least problems. ATM I am struggling with Magisk. The Magisk/Samsung instructions are understandable (although I am not sure if I understood it correctly), but I don't know why I should flash with fastboot (which ATM doesn't detect the device), when others use ODIN/heimdall. And the specific s5e description on the TWRP site is really confusing me. https://twrp.me/samsung/samsunggalaxytabs5elte.html ("first root with Magisk, the pre-root with TWRP, otherwise need to take care manually of something" Maybe rooting is less problematic with the Lineage Recovery?

Maybe I buy so rarely a new device, that the changes in between are so much that everything is new for me again.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] LuK1337:
This is stock ROM recovery, if you want you can google lineage recovery and see how it's supposed to look like.

You most likely rebooted to stock ROM after flashing lineage recovery, which then restored stock ROM recovery.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] Cepasaccus:
Thanks. Will then try to move to lineage and see how I get magisk into this.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] Cepasaccus:
Tried to load it again with heimdall and, well, it indeed looks much differently. Reason for my first problem found. I didn't know that Samsung device has a recovery. Never seen one on my S10e and on my S2.

If I feed this recovery img to magisk, it returns me a modified img. Do you think it is a good idea to heimdall it?

PS: The modified img didn't change a thing. :-(

PPS: Tried this one: https://xdaforums.com/t/galaxy-tab-s5e-sm-t720-root-instructions-release-1-0.3947806/ Flashed with heimdall --RECOVERY. lineage recovery still present. No root.The power+up until "powered by android" screen just brings me into recovery. Will try to flash it somewhere with ODIN.

PPPS: ODIN flashing of the Samsung AP package works. Flashing of the assembled magisk_patched.tar fails. I have no idea what I could try next to get it rooted. I guess this will be a Firefox-only tablet.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] Cepasaccus:
Works now.

Lesson: Ignore the complicated stuff and go back to the basics.

I flashed Lineage Recovery and Lineage OS, applied then the Magisk apk renamed to zip in the recovery and its root. The only error/warning was a bad signature of the Magisk zip, but that doesn't stop the recovery. After Lineage update I had to reapply Magisk zip, which went again without a problem.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] androidtel:
Hi,

for updating 19.1 with TWRP 3.7.0 there is a workaround if you have an external microSD card. After downloading, the updater offers the possibility to save the zip file to the external microSD card (not encrypted). Reboot into recovery TWRP you can flash the zip update and the magisk zip (saved on the microSD as well) on top. I'm not sure why, but the update works. Backup and restore with TWRP as mentioned above not.

Thanks mate!
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] Brodelpiet:
You need to enable USB Debugging. Turn on root Access for ADB in the magisk settings and then open up a adb shell (adb run shell). Then enter "props" and set device keys via menu.

You could also use Termux or another terminal Emulator. But before entering "props" you will have to make yourself a super User via su

Definitely smoother and less bloated. TWRP is an advantage too. I always liked crDroid and I had it installed on other devices, it's a very solid rom with actually no bugs. Some things I miss from stock like floating windows, but in general I think I prefer AOSP

Not exactly out of nowhere, because on 18.1 each start of the TWRP's backup was followed smth. like " FS decrypted with default key", so i have a vague hope; on the other hand, TWRP's file manager is an obvious backdoor.

First timer here. Read through the entire thread and did some googling, but still having issues after completing the process. When I rebooted my tablet after (what I thought was) successfully flashing 19.1 (and perhaps unsuccessfully flashing Gapps altho I can't tell since the signature failed prompt is expected) the device just rebooted into the stock OS.

Some troubleshooting questions:

Is TWRP mandatory for the process? I saw that When the instructions got to this step, I assumed that the recovery.img was referring to the file in the Unofficial folder.

At what steps can I continue the process? Or do I need to restart from the beginning? When I restart the tablet, I still get these prompts suggesting that at least some of the process was successful.

For Gapps, I'm assuming I just d/l the most recent version available, yeah?

Thanks in advance in helping me figure things out.
