Hi All! When i try to reboot my phone, it always gets stuck on the Samsung logo... the only way for me to get back into the phone is "TWRP - clear cache and dalvik cache" I'm running 8.0 oreo with xposed 90 beta3 and TGPKernel 2.5.3. I'm afraid it won't boot up next time!
[Samsung Galaxy S8 & S8+ Cross Device Development] usatencu:
For sure you have a problem with your phone or apps. For me screen off drain it s zero. I tried all kernels and this is the best for battery

Hi guys,

i get a bootloop flashing the last version, ticking magisk, spectrum and wipe supersu and magisk, am i doing anything wrong?

regards.
[Samsung Galaxy S8 & S8+ Cross Device Development] ACardAttack:
Last time I flashed this with Alexis Rom wifi no longer worked, it would turn off as soon as I turned it on, I wiped dalvik afterwards, any idea what might have caused that issue?
[Samsung Galaxy S8 & S8+ Cross Device Development] phsetaknev:
Samehere, its stuck at the Samsung Splash screen. I manually rebooted it (Volume Down + Power) but then everytime I restart its entering bootloop. So annoying
[Samsung Galaxy S8 & S8+ Cross Device Development] brunsman6229:
Hello [MENTION=4280397]djb77[/MENTION], before thanks for your work ! i have a problem, i am on stock rom with your latest kernel, but now my wifi don't work ! impossible to enable wifi..! before i was on velocity kernel, because i can't restore my boot backup ( TWRP) it bootloop. Also i have flashed directly your kernel. Can you help me please..?
[Samsung Galaxy S8 & S8+ Cross Device Development] redhunter22:

[Samsung Galaxy S8 & S8+ Cross Device Development] ItsmYarD:
Same issue here with the others, gets bootlooped
[Samsung Galaxy S8 & S8+ Cross Device Development] M3th0s:
Same issue here when flashing the kernel.

I could be wrong but I think it's detecting the rom as an s9 port when it isn't. Again, good thing I had another kernel to flash in recovery mode.
[Samsung Galaxy S8 & S8+ Cross Device Development] burza_:
I had no issue during install 2.5.5 nor 2.5.6. Everything smooth as it should. I am on Renovate Ice R135.

I have great battery life with this kernel on stock config :)
[Samsung Galaxy S8 & S8+ Cross Device Development] Ogy77:
WiFi not working on latest kernel version?
[Samsung Galaxy S8 & S8+ Cross Device Development] M3th0s:
Forgot to mention I was using LightRom, but not the s9 port.
[Samsung Galaxy S8 & S8+ Cross Device Development] kevinwu128:
Me too! What have you done to fix this?

Actually, I get a lot of random reboots, do you get this too?
[Samsung Galaxy S8 & S8+ Cross Device Development] phsetaknev:
I just re flashed the ROM and Kernel one by one without restarting, installed all the apps, took a back up, and then flashed Xposed from Magisk. I kept taking backups before flashing anything else (like mods) and now its stable.

I am not getting any more reboots. But the battery life isnt that great!
[Samsung Galaxy S8 & S8+ Cross Device Development] Ogy77:
Any fix for wifi?
[Samsung Galaxy S8 & S8+ Cross Device Development] roizcorp2:
I'm facing issues since 2.5.5, keeping 2.5.4 kept Amabasadii ROM 3.8 CRF7 stable, but now when it gone into CRG1 breaks everything, I tried TGP 2.6.0 and still it broken
[Samsung Galaxy S8 & S8+ Cross Device Development] mawxzz:
Its not working anymore qith alexis rom 5.5

It gets stuck after samsung and just blank black screen
[Samsung Galaxy S8 & S8+ Cross Device Development] ZcoderDEV:
Because TGP kernel doesnt merged with CRGB source, then it wont work on CRGB based roms

[Samsung Galaxy S8 & S8+ Cross Device Development] nearglen:
I saw that it said a while ago that the universal dex patch was applied, and it says enabled in the description but when I put the Kernal on, it did not work. I am back on NX kernal while I figure this out. My issue was the NX took out drivers for touchpad on the HPlapdock. I couldnt even use it when in screen mirror mode.

Please help me, maybe when going through aroma i did not select something?
[Samsung Galaxy S8 & S8+ Cross Device Development] burza_:

You don't need free ram on android. Free ram is wasted ram,.
[Samsung Galaxy S8 & S8+ Cross Device Development] xFirefly93:
Enforcing is the only thing you'll ever need on a Android device, mainly for security reasons.

No matter what.
[Samsung Galaxy S8 & S8+ Cross Device Development] Noxxxious:
I assume you also dont root
[Samsung Galaxy S8 & S8+ Cross Device Development] xFirefly93:
I have rooted all my listed Android devices, and AFAIK - all of them is set to Enforcing Mode (except my XZ1).

EDIT: My bad. I had the perception that it was possible to bypass Enforcing mode by using some "ugly" hacks and workarounds and still being able to fully root w/o any issues/problems.

My devices are all set to permissive mode, now that I double-checked for security coats. Lol.

Hey guys. Please help.

I want to flash this kernel on renovate 13.4 for save battery

However, i dont know choose whats in aroma.

How to use mtweaks ?? Too many settings
[Samsung Galaxy S8 & S8+ Cross Device Development] dmartuniac:
If you don't know how to use mtweaks, leave the default settings. Messing with the governor settings afects your battery life, phone can got hot etc. Just flash it and leave it as it is.
[Samsung Galaxy S8 & S8+ Cross Device Development] xperia modder:
Guys , i really need help with this problem, like every other kernel i use except nx14 gives me this integrity verification failed , like i tried nx 15 16 , and then i tried tgp and i tried then velocity , but nothing seems to work always this msg am on alexis 5.5.1
[Samsung Galaxy S8 & S8+ Cross Device Development] ngochan1102:
should i clear Dalvik/ART cache before flash this kernel?

should i choose whats in aroma?

spectrum, enforcing, disable auto sleep...

im on alexis rom 5.6.1 NX r16. i want change. im very nervous :cool:

thanks you
[Samsung Galaxy S8 & S8+ Cross Device Development] SandeepEmekar:

Thank you!
[Samsung Galaxy S8 & S8+ Cross Device Development] dmartuniac:
Clear dalvik and cache only if you are on deodex rom. Select spectrum if you want to choose betwen performance/balance/battery.
[Samsung Galaxy S8 & S8+ Cross Device Development] Noxxxious:
Try format data with nx15/16/velocity/tgp

Very slick kernel, just wish battery life was as good as Nox, I'm seeing about a 20% difference.
[Samsung Galaxy S8 & S8+ Cross Device Development] pep086:
NX gives you better battery than this? i'm curious about your settings, this is the best kernel for battery i tried all of them, nx, noto, mad max and velocity.

i get 6 hours SOT, can't get it to last longer :S
[Samsung Galaxy S8 & S8+ Cross Device Development] artaniss11k:
You are right. It's the best kernel for battery life.

Try also to downclock big cores to 2002 mhz and little ones to 1456, set max gpu freq to 455 ang gpu high speed freq to 385, and then check your SOT again ;)
[Samsung Galaxy S8 & S8+ Cross Device Development] pep086:
i got 6 hours with big clocked to 1200mhz and little ones on 1450 mhz, spectrum on battery, gpu on 385mhz.

using amplify and greenify and appsopps xposed. i don't know how to improve it more xd
[Samsung Galaxy S8 & S8+ Cross Device Development] artaniss11k:
Don't downclock to much becauce the cores will work longer than with a higher frequency. For me 1937mhz for big cores is enough.

Try disabling spectrum or set it to balanced. I got les SOT with spectrum on battery profile.

In MTweaks under the HMP tab set Up Treshold to 535 and Down Treshold to 225.

Also if you don't play games set both governors to conservative, otherwise set them to interactive.

I got 8 to 9 hours SOT with these settings and i don't use greeenify, amplify or other stuff, just AlexisXDA rom and latest TGP kernel with these settings.

You don't need thirdparty apps for battery life becauce you have Samsung SmartManager and under the battery tab you can set wich apps to stay closed so they won't consume battery only when they are opened.

If in TWRP directly after installation please try to tap two times the power button of your phone.
