My LuisKERNEL (PIE/TEN) for Samsung Galaxy Tab S5e (gts4lvwifi/gts4lvlte)

Notice
I like to share my work for my Samsung Galaxy Tab S5e (LTE). I have compiled this kernel so that my Galaxy Tab performs better and rooting with Magisk works better.
I'm testing this kernel on my Samsung Galaxy Tab S5e (gts4lvwifi) device and I think it should work on the Samsung Galaxy Tab S5e LTE (gts4lvlte) too.
The kernel I use on the latest Samsung Stock ROM with Magisk 20.3 and Magisk Manager App + Ex Kernel Manager.
The source code is a fork from the official LineageOS 17.1 sources.

The kernel runs for me with LineageOS and Stock Samsung ROM.

Sometimes I get a lot of help or feature requests from users of my LuisROMs and LuisKERNELs. My dog Luis and I try to fulfill most of the wishes, but that is not always possible. I do that as a little hobby and Luis does not always want to build ROMs :). Please understand if I can not always answer directly.

Kernel: I have pached up the Kernel to Linux 4.9.217 with many mods other devs (thanks to @LuK1337 for the base an incredible work!)
  • Pached from 4.9.112 up to 4.9.217 from caf
  • Removed lots of excessive bloat (improves security and performance)
  • Improved stability (several bugs not listed here have been fixed)
  • Boeffla Wakelock blocker driver V1.1.0
  • More I/O-Schedulers (fiops, sio, zen, maple)
  • Added fsync on/off support.
  • Disabled crc check
  • Optimized for performance and battery life
  • Compatible with EX Kernel Manager
  • Compatible with systemless root (recommend Magisk 20.x or higher !!!)
  • Wireguard kernel support
  • Many other misc. improvements not listed here

First time installation:

Update:

Downlads:

Kernel source:

Enjoy!

Just got the device today, Happy to see a kernel is available for the device.

Shall try it once I confirm device is working fine ( to void warranty). Feel the device is pretty sluggish with default kernel.

Does this kernel have kcal support?

Thanks a lot for the kernel.

I bought a used tab s5e from a local electronics store for less than half of the msrp. I then discovered that it wouldnt charge past 70%. Later I peeled off the sticker on the back and the tablet said 'not for sale'. It turns out that this was a display unit and these are configured to not charge past 70% to protect the battery. I didn't want to return it because it was a really good deal even if it doesn't fully charge. My question is will flashing this kernel allow my tablet to charge to 100%? Or this kernel will not be compatible with it? Thanks in advance.

There's an option in the battery settings that limits the tablet from charging beyond 85% to extend the battery life, you can take a look at that first. If that doesn't help, you can try a custom ROM and Kernel. Start with the kernel, as it is less intrusive. but to be honest, I have no idea if that would help. You can also try a factory reset.
If I was a betting man, I'd bet on Samsung limiting that device's charging capacity though the ROM.

Thank you.

Thanks for your method
Magisk V20 and V21 (Canary) have problem with T720 and gives vbmeta error.
Your method makes V21 (Canary) successfully installed as well as ROM up to date.

(omitted. See first post)

Try to install official full ROM (use Frita to grab ROM) and flash with Odin (CSC to wipe everything) and see first.
If everything works as it's supposed to, do everything at first post (flash kernel as boot)
You may need to install Magisk Manager and you may need to run few setup for it.

[kernel] [pie] [9]

After installing [KERNEL] [PIE] [9] LuisKERNEL GTS4LVLT, the tablet appeared in the device manager. But it is not visible in the conductor and nothing can be copied to the micros. Is everything visible in the conductor with the stock carnel. Is this a problem?

I have the same problem. I get the error "The connected device is unable to access data on this device." That seems to be the only problem. I can't move files between the tablet and the PC. I have the 128GB Wifi version. I'm on stock Pie firmware with this kernel and rooted with Magisk v20.0.

Same here. No connection to PC

Results of yesterday's experiments: 1.Installed stock Rom (tablet launched and it can be seen in the Explorer) 2.Installed TWRP (tablet launched and it can be seen in the Explorer).3.Installed Magisk (the tablet did not start.Constant restart).Installed LuisKERNEL (tablet launched and it is not visible in the Explorer).

I've got the same problem at the end as well. My computer wasn't able to identify the tablet.
