[KERNEL][PIE/TEN]LuisKERNEL Linux 4.9.215 for GTS4LVWIFI & GTS4LVLTE devices

[bs3pro]

Yes would be great to have this kernel operating with Stock Android 10... is that a possibility 8224Freak?

I agree. Would love this on A10

Functionality

I've been reading up on Rooting & TWRP this tablet which is due to arrive soon.

AHE_XDA has written an extremely good and clear guide on Rooting with the stock kernel but there seems to be an issue with installing TWRP and rebooting.

However this Luis Kernel seems to do away with all the faff and provides straight forward regular Magsik & TWRP install. Does using this kernel on stock ROM effect the functionality of the device in any way?

The reason that i need a working TWRP is that I'm planning to have a stock ROM with MicroG as per the instructions here. I've already done it on my Nexus 5 and OnePlus 5T.

Thanks.

I tried to flash it over LineageOS 17.1 from nearby thread, and it fails to boot, then drops to TWRP. Various attempts with different versions of kernel (TWRP imgs flashed to Boot) plus Magisk - doesn't want to boot. Take backups to save time.
Ended up coming back to default kernel of LineageOS manually extracted from latest release zip.

I'm having the same exact issue. How did you extract the default kernel as reflashing LOS didn't work for me either?

LOS zip contains "boot.img", I took it out from zip with my version of LOS and flashed it to Boot partition in TWRP (same how this Kernel was flashed).
After that, Reboot to system should work just fine.

Here's one from build dated 2020-09-21 to save you time/traffic.

I thought that was it and tried it but it didn't work for me. Same issue, just fails to boot fully and goes back to twrp. I may just have to start from scratch and try to restore data.

Could also try to flash magisk over it. Maybe some root specific conflict. Default LOS boot.img is rootless.

On the side note, I'm curious how to identify what went wrong with this current kernel. Is it simply not compatible with LOS 17.1?

Reflashing LOS, GAPPS, Magisk, then restoring data worked for me. I haven't flashed custom stuff in ages so I did not make a back up but backing up and restoring just the data appeared to worked fine. For the latest kernel, I did notice it listed Aug as the security update so that could be why?

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:

• Unlock the bootloader, 1. Connect to WiFi network, 2. Enable OEM Unlock in developer options, 3. Turn off the tablet, Boot to download mode manually by plugging in USB and holding all the buttons for few seconds, 4. Follow instructions on the screen
• Connect to WiFi network and make sure OEM Unlock in developer options is still checked
• Flash custom VBMeta image ( http://luis-builds.de/downloads/lineageos/cr/Samsung_Galaxy_Tab_S5e_(gts4lvwifi)(gts4lvlte)/vbmeta.tar ) in Odin ( use AP slot )
• After flashing VBMeta, boot to stock. It'll likely ask you to wipe data, if so do that
• Connect to WiFi network and make sure OEM Unlock in developer options is still checked
• Now you can flash TWRP ( gts4lvwifi > https://dl.twrp.me/gts4lvwifi ) or ( gts4lvlte > http://luis-builds.de/downloads/lineageos/cr/Samsung_Galaxy_Tab_S5e_(gts4lvwifi)(gts4lvlte)/twrp-3.3.1-0-gts4lvlte.img.tar ) in Odin ( use AP slot once again ), for convenience you can hold volume up while flashing it so that you boot to recovery right after it's flashed
• Boot into TWRP (press power and vol+)
• Install latest LuisKERNEL (.img) LuisKERNEL-4.9.XXX-twrp-2020XXXX.img
• Optional: Install latest Magisk https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
• Reboot ( make sure to not install TWRP app when TWRP asks you to )

Update:

• Boot into TWRP (press power and vol+)
• Install latest LuisKERNEL (.img) LuisKERNEL-4.9.XXX-twrp-2020XXXX.img
• Reboot ( make sure to not install TWRP app when TWRP asks you to )

Downlads:

• Link cr LuisROM & LuisKERNEL: http://luis-builds.de/downloads/lineageos/cr/Samsung_Galaxy_Tab_S5e_(gts4lvwifi)(gts4lvlte)/

This kernel doesn't work on a10. The op should fix the title.

yea.. i give up to use this kernel.. now i ady root my tab s5e lte using magisk then i keep it that way.. thanks for reply bro..

 

[Mrxyzl]

No more update for stock 10.0?

 

[mac231us]

TWRP (LTE version) still good for Android 10?

This kernel doesn't work on a10. The op should fix the title.

How about twrp? Is it still applicable for Android 10? I have the LTE version.

I went back to Android 9 for the sake of getting TWRP and root but if it can be accomplished on Android 10 then I will update and then try the BL unlocking etc from there. Thanks.

Understand that the kernel is only applicable to Android 9.

Thanks (anyone who can advise)

EDIT if bootloader unlocking is a prerequisite (fully understand that) how can this be possible "make sure OEM Unlock in developer options is still checked" (AFTER the unlocking) (at the most it would be greyed out-in my case Android 9 or 10 it just vanishes once the BL is unlocked-which makes sense to me at least)

OP states "Unlock the bootloader, 1. Connect to WiFi network, 2. Enable OEM Unlock in developer options, 3. Turn off the tablet, Boot to download mode manually by plugging in USB and holding all the buttons for few seconds, 4. Follow instructions on the screen
Connect to WiFi network and make sure OEM Unlock in developer options is still checked"

Exactly the same for me. Thanks for explaining how to flash back the default lineageos kernel from boot.img.

 

[z00man]

Not "LuisKERNEL-4.9.XXX-twrp-2020XXXX.img" available anymore?

 

[mrdark5555]

Does anyone happen to have the last version of the LuisKernel that was released? It isn't available on the download site any longer. Thank in advance.

@8224Freak Any chance to revive your kernel for this tab on Android 10 or even 11? Regards
