[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] HolGer749:
Hi there, coming from LOS 16.0, I wanted to update the tablet and forgot to move the latest LOS 18.1 nightly to internal storage before. Because a problem arose that I hadn't expected: Updating the firmware caused the tablet to not boot beyond the clock screen. I currently have...

the latest firmware running

the latest TWRP running

no OS installed

TWRP no longer lets me install the LOS 16.0 zip that is still on the internal storage -> shows error message.

Any idea? Is there any way to install the LOS 18.1 zip using Odin?
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] LuK1337:
Why won't you just install 18.1 in TWRP then?
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] HolGer749:
Because the 18.1 file is not yet on the internal storage. At the same time, no operating system is currently installed. So I either have to find a way to move the 18.1 file to the internal storage (or getting it installed via Odin) or I need an older firmware that was used at times of 16.0 to undo the process. If you can help it would be greatly appreciated.

I'm getting pretty strange behavior. Once in a while I loose access to all mounts for the main user (emulated/0 mounts) and every other time I backup to the SDcard it mags that there's something wrong with the card (even when brand new). After a reboot all is well again.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] nostupidthing:
LOL clearly @LuK1337 is trolling you. That being said, I believe most LOS devs are volunteers. So feel free to go take something else. You'll certainly not be missed here LOL.

Such entitlement, I don't understand. Hahaha.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] gnarf49:
Thanks @LuK1337 for this ROM! It built and installed exactly as advertised :-) and runs great, incl. keyboard cover support which I was afraid to lose with custom ROM (building myself with MicroG signature spoofing patch)

Hi Experts, few questions (pls forgive if stupid or already answered, I tried the search function...):

1. The S5e encrypted itself on first start without me asking for it, I can't access /Data from TWRP anymore. Not sure why that happened, my S9 installed same way did not auto-encrypt. Is there some switch or setting for this?

2. Is there a way to enable f2fs and Wireguard kernel mode? Or is kernel 4.9 too old?
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] t3chg33k:
Samsung will be trawling through this thread and the thought of losing Motans' money to LuK1337 will get them to immediately switch to supporting LOS 19 themselves.

It takes some kind of special to have that kind of entitlement indeed.

Is it possible to install these via adb?

I am on linux and I don't know how to install this not using odin.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] LuK1337:
Yes, you can install it via dd it if you reverse engineer how stock rom recovery disables write protection on critical partitions.

Wrt flashing firmware without Odin/Windows:

Alternative for Samsung devices is heimdall-flash, should be available as deb package in Ubuntu/Debian. There's even a GUI for it.

In my case for SMT720 Heimdall did not work so I had to start a Windows VM and flash TWRP via Odin. On my other Samsung tab Active 2/SMT395 trying to root with Magisk it was the other way round, Odin said success but no root, Heimdall did the job. No idea why :-)
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] LuK1337:
Only Fedora/Arch ships patched Heimdall that's able to interact with this device FYI, that's why your Debian one didn't work.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] Riigel:
For a while now, I have been having problems with the touchscreen on my tablet.

(I'm not sure if the problem already existed before installing this rom).

The problem is that the right edge (3cm) no longer responds to inputs.

I have already completely reset the tablet (original Samsung) and

then performed a reinstallation of Lineage (instructions post 1).

After the reinstallation, everything worked normally for several days

before the problem occurred again.

Today I did a Lineage update (dirty) and after logging on to the system, the screen

also worked normally for 2-3 minutes.

It feels like the borders of the screen are pushed too far to the left.

Could this be a software problem or is it due to the hardware?

Has anyone else had this problem?

Hey guys,

I just tried to get LOS running on my new S5e. Getting to the unlock menu was a pain but it shows the following in the download mode now:

FRP LOCK : OFF

OEM LOCK : OFF (U)

KG STATUS : PRENORMAL

WARRANTY VOID : 0x0

QUALCOMM SECUREBOOT : ENABLE

SECURE DOWNLOAD : ENABLE

However, when I to flash vbmeta.tar with Odin this fails with "<ID:0/003> FAIL! (Auth)"

On the Tablet I get the message: "Only official released binaries are allowed to be flashed(vbmeta)"

Guess this might be related to QUALCOMM SECUREBOOT : ENABLE or SECURE DOWNLOAD : ENABLE

Did I miss something or was it a bad idea to update to latest stock rom before did the flashing attempt and samsung changed something to prevent flashing in the latest update?

//EDIT: In developer options it also shows the the boot loader as unlocked and the option is grayed out (because it cannot be changed back until the boot loader is relocked I guess)

/EDIT2:

Flashing vbmeta worked after some more tries. I have no idea why however....

Also there seem to be download modes that behave different. If I use "adb reboot bootloader" I am in a green download mode without any details. This one failed completely on my first attempts. If I use vol-up + vol-down + power and usb cable connected(!) I get the download mode with additional details on locking state. And this one behaved totally different. Flashing seemed to work but ended in the error mentioned above. Another try in "normal" boot loader however worked for whatever reason.

Can anyone explain where is the difference in the two download modes and which is supposed to do what?

But still I am stuck. I also can flash the new recovery in "normal" download mode but after flashing it instantly reboots to Android which seems to overwrite Recovery again. At least it still looks the same after reboot and ADB sideload fails...

Never ever had such an annoying device before. oO

Any Ideas on how to get to LOS recovery before stock rom boots again?

//EDIT3: After endless tries it finally worked somehow and I am on LOS now.
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] topaza:
I would like to root the device and I did some research and found that Magisk can only be installed to recovery on this device and there is a "patch file" option in magisk app. However I have no experience with this way of installing Magisk and before I break something, I would like to ask some questions:

1) Can I just use the app to patch the LOS recovery.tar that I used for installing LOS and then flash the patched file with Odin to AP Partition?

2) Is it the same with TWRP? Can I just patch the latest TWRP tar file and flash it to AP partition?

3) Is there any advantage in choosing LOS recovery instead of TWRP?

4) Will Magisk survive LOS update if I uncheck "update recovery" in LOS updater settings?
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] JJ2017:
Having just upgraded to Magisk v24 this was how I did it:

1) extract boot.img for the ROM you are using i.e. from the installation package (.zip)

2) install Magisk Manager (download from github if you don't already have it)

3) use Manager to patch the boot.img file - it will save to your device somewhere

4) boot into recovery, flash the patched boot.img using TWRP

Hope that helps
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] topaza:
Thanks for the guide. In the meantime I also found out that installing Magisk on LOS is much easier than on stock rom. :)

I did it a little different than you and just flashed the magisk.zip from TWRP. This also works fine for now.

Do you know if patching the image has any advantage over just installing the zip file?
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] JJ2017:
That's good to know - I just followed methods on this thread - like you, I was wary about just flashing it and hoping!

If it works, it works - can't see why patching boot would be advantageous but happy to be corrected, if someone knows better (y)

I have a USB-C hub (BL10V), which has a RTL8152 Ethernet port on it, along with audio, video, USB A, SD, PD. Everything else works apart from the Ethernet. When I connect it no Ethernet item appears under Networking. No mention of 8152 or Ethernet in dmesg or lsusb.

When I connect it to my laptop I see it appear in dmesg and lsusb.

I have tested on my mates Galaxy S9, stock ROM, where it works perfectly.

I did try it on my s5e stock ROM briefly before flashing LineageOS where it also did NOT work. Ethernet was present under Networking, but greyed out, and stayed greyed out.

Thanks for keeping with these ROMs, I really appreciate it.

I'm running into a minor issue, though. I did a fresh install when upgrading to LOS 18 from 17.1. I'm on TWRP 3.4.0-4. I wiped all the partitions, formated data, and got myself set up. Installed 18, added my PIN and fingerprints, got my apps set up, and everything looked great.

Then, I went back into TWRP, and it can't decrypt and says my password failed. So I booted back to the ROM, removed my PIN and fingerprints, and tried going back to TWRP. This time, with no PIN set, it worked great.

Is anyone else experiencing anything similar?
[Samsung Galaxy Tab S5e ROMs, Kernels, Recoveries, ] Riigel:
As far as I know Samsung is using a new encryption which is currently not supported by TWRP.

So you always have to remove your pin and fingerprint if you wanna use TWRP.
