[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] Naster24:
I tried something new and I have interesting results.

I installed a Firmware U, it is a version of android 7. I installed it by odin and everything well without problems. When I restarted I put the SIM and it told me that I had to restart to configure the options of my operator. It restarted without problem and to my surprise it CONTINUES without Signal. In '' Access Point Name '' the APN of my operator's MMS has been created ONLY and AUTOMATICALLY. I did not set it up, it came out alone.

I still do not understand what problem this phone has. There are several people reporting similar problems with the upgrade to Oreo even in other S7 EDGE models.

Any ideas?????
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] mikepfly2:
Newb question but if I flash this official firmware on my Verizon s7 edge using Odin will I trip Knox? I like using Samsung pay & don't want to risk it.
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] SoNic67:
Check to see if is correct, they don't have all the APN's and sometimes they put other ones. You can edit that APN with the correct one (from your provider website).
[Verizon Samsung Galaxy S7 Edge Guides, News, & Dis] Maxissc:
No you won't, since it's an official firm. As long as you don't root samsung pay will work

If you flash i recommend you to do a clean install, using CSC (Not HOME_CSC). Remember this will delete all your internal storage files (pictures, downloads...) so make a backup before. home_csc won't delete anything, but you may encounter some fc or lags

Anyone know where I can dl the Odin image for G935VVRS4CRI1? I'm trying to factory restore my phone and then use the root method. Quick question though, after rooting can I install magisk to use the magisk modules?

Velocity Kernel • Galaxy S8/+

by kdrag0n

This kernel has been abandoned.​

Unfortunately, due to a lack of time, I have decided to abandon this kernel. Thanks to everyone who supported this project while it was alive.

The original post is available below for reference.

Flash at your own risk.

Introduction

Velocity Kernel was made to provide the best possible experience on all devices. We strive to provide the perfect balance of performance and battery life. Features are also plentiful, but features that nobody uses will not be included. We also completely debloat all our kernels and aim for small sizes relative to other kernels. Due to the small size and careful debloating, boot time is also improved.

Compatibility

All Oreo ROMs are supported. Magisk is automatically reinstalled if you already have it installed. Deodexed ROMs should be supported. SELinux Permissive and Enforcing states are available for you to choose.

Features

Downloads

Downloads can be found here on GitHub. The topmost release is the latest, currently v11.

Make sure you download the "VelocityKernel-s8-v11.zip" file, not "Source code". Downloads are in the Releases section, not Tags.

After install bootloop
[Samsung Galaxy S8 & S8+ Cross Device Development] Enrico0815:
Flashed it over Nox Kernel and bootloops
[Samsung Galaxy S8 & S8+ Cross Device Development] artaniss11k:
It is called MTweaks. You can find it in TGP kernel thread.

If you don't find the app itself, download TGP kernel and extract it from the zip file.

By the way, I'm not using other third-party apps for battery savings, only kernel related settings, Samsung's device manager and some simple things inside the phones settings like only 3g instead of 4g, nearby devices to off, resolution to 2280x1080 and so on.
[Samsung Galaxy S8 & S8+ Cross Device Development] pep086:
Kdragon,

last release is SUPERB, getting 7 hours sot with normal use, fb, Instagram, etc. but restricted a lot with amplify and greenify. even better than TGP.

thank you so much!

Dear Sir, after installing your kernel, I am not able to install another one .... screen freezes in boot .... any clue ?

Many thanks in advance
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
What "screen"? Boot animation, bootloader splash, lock screen? Which ROM? Which kernel did you come from? Did you pick Permissive or Enforcing during installation (volume down/up)? Which device model?
[Samsung Galaxy S8 & S8+ Cross Device Development] Jostian:
Great kernel but in better battery stats I'm seeing a kernel wakelock called abox eating a lot of battery, any ideas?
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
That's an audio wakelock. It usually indicates how long you've been actively using the speakers or headphone jack.
[Samsung Galaxy S8 & S8+ Cross Device Development] Jostian:
Strange, haven't listened to any music and haven't had headphones in for days... And don't watch movies or anything, and the wakelock was during the night while phone sleeping... So very weird.
[Samsung Galaxy S8 & S8+ Cross Device Development] maej72:
Here you go friend and thanks for the help in advance.
[Samsung Galaxy S8 & S8+ Cross Device Development] Jostian:
strange, I'm having random reboots, especially when my phone goes into sleep/standby (screen off) the phone reboots I have cleaned cache/dalvik etc. any idea's?
[Samsung Galaxy S8 & S8+ Cross Device Development] Ringanar:
Wich app can i use to undervolt ?
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
None. It's built into the kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] CHiBLaST:
Can i ask which rom are you using?

I m going to use this with LightRom Oct 10 build with latest modem, bootloader. Lets see how its going.
[Samsung Galaxy S8 & S8+ Cross Device Development] Mangtas_666:
This Kernel is rocking at Carhd Rom.
[Samsung Galaxy S8 & S8+ Cross Device Development] Jostian:
Love this Kernel but for whatever strange reason I'm having random reboots, especially when my phone goes into sleep/standby (screen off) the phone reboots I have cleaned cache/dalvik etc. Could it be Xposed or magisk related, any idea's?

No issues with NX17 kernel but i would prefer using Velocity.
[Samsung Galaxy S8 & S8+ Cross Device Development] Mangtas_666:
What rom are you using?
[Samsung Galaxy S8 & S8+ Cross Device Development] Jostian:
SolDier 10.2
[Samsung Galaxy S8 & S8+ Cross Device Development] galaxyYtester:
I had the exact same problem on LightROM S9 port and Nova S9 port, installing in SELinux permissive mode (volume down) instead of enforcing (volume up) fixed the problem for me. Amazing kernel overall, face unlock speed and general responsiveness have never been this fast on an S9 port ROM before.
[Samsung Galaxy S8 & S8+ Cross Device Development] Jostian:
Ah thanks i selected enforcing, will try permissive, thanks
[Samsung Galaxy S8 & S8+ Cross Device Development] artaniss11k:
Alexis Rom 5.5.1 with latest bootloader and modem.

On yashduster's LightRom I have WiFi issues.

By the way, SOT is determined on how you use your phone. I had 10 hours SOT with lite usage but I had even 6-7 hours SOT when heavily gaming playing Asphalt 9 and Eisenhorn Xenos
[Samsung Galaxy S8 & S8+ Cross Device Development] Jostian:
I don't get the option to select permissive or enforcing, it automatically installs as enforcing... :(
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
That'd be because you've already selected Enforcing. Delete the .velocity_settings file in /sdcard. It's a hidden file, so you'll need to configure your file manager to show those. I'll make this more visible as velocity_settings.txt in the next release and possibly give a 2-second choice period even if it's saved.
[Samsung Galaxy S8 & S8+ Cross Device Development] Jostian:
Thanks, but even after selecting permissive phone reboots everytime screen goes off? Weird. Tried Nox 17 and TGP and both are fine, so have no idea what in R9 is causing these reboots on SolDier 10.2 ROM.
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
This is most likely caused by the I/O scheduler switcher that automatically switches to noop when going to sleep. It's been reverted, so r10 will have the fix.
[Samsung Galaxy S8 & S8+ Cross Device Development] Jostian:
The abox kernel wakelock is still there at the top of the battery drain list, battery drained 12% during sleep. Nox 17 and TGP have this wakelock but it's like 1% of drain.
[Samsung Galaxy S8 & S8+ Cross Device Development] CHiBLaST:
I use this kernel with LightRom 8.0 with latest modem and bootloader. Here is the status update.

Everything is stable and really smooth. But what about battery life? Battery life really depends. It drops %100 to %95 in 30 mins SOT Its amazing right? But what about after? When I m writing this message SOT is 2 hours 16 mins and battery at %50. So what i did in this 2 hours? Well I played Honkai impact3(really demanding game) about 1.30 hours. I guess I have to tune the kernel when I go to home.

My sync,gps,4G were open all time so this drains battery more. Brightness is auto and screen is WQHD.

Also I played Guns girl straight 6 hours. But it isnt a demanding game still 6 hours SOT is amazing.

With a little tweak you can create a epic battery life with butter smooth phone. This is my observation.

Thanks for this kernel.

[Samsung Galaxy S8 & S8+ Cross Device Development] dmartuniac:
I like the new update. One small question anyway.

I looked with kernel adiutor at the interactive gov values. Aren't those a little bit orientated to performance?

I mean, high-speed freq is 1.9 ghz for the big cores.

I know we can tune the gov how we want, but not everyone know how to do it.

Later edit: My bad, i restarted the phone and now the values are stock. I don't know what happened.

[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
Which kernels work? Which kernels don't? What ROM are you using?

Format data (DO NOT WIPE, instead Format Data on the Wipe screen) in TWRP and try again.

If that doesn't work, flash the full stock firmware with Odin and relock the bootloader after you're booted. Wait a few minutes (or days potentially if it locks up) and unlock the bootloader again. Install TWRP, Format Data (on the Wipe screen) first thing, then flash your ROM of choice and the kernel after.

Kudos to the dev for the flicker-free display driver.
[Samsung Galaxy S8 & S8+ Cross Device Development] xperia modder:
Well am using alexis romm 5.8

And now am using nx v17

And the kernels that are not working

Are velocity(yours)

And tgp

And the wierd thing is

When i was on alexis 5.6 even nx 17 wasnt working

Which i dont understand why when i came preinstalled with alexis 5.7 or now it works

I will try to format data and if it doesnt work am going to flash stock hopefully it will work , becaues i have always wanted to try this kernel but i always get the integrity verification error
[Samsung Galaxy S8 & S8+ Cross Device Development] mfitm:
I am also using Alexis 5.8 and latest velocity and haven't had any problems.

Are you shure you have the latest firmware (CRJ5)?

I am on renovate-ice 14.1, since I installed this kernel, I am having media.codec battery usage. Espacially high...

I don't know where it came from. Can anyone help.

And this problem didnt happen with nx kernel why is it happening with this one :/

I get endless android web view (70) crashes

and Wi-Fi direct crash on startup

(Ambasadii 5.6 ROM, does not happen w/ TGP)
[Samsung Galaxy S8 & S8+ Cross Device Development] parser:
I wanna use this kernel really but I couldnt get the performance I get on NX kernel (renovate ice 14.1)

When I checked both kernels usage stats in mtweaks (cpu tab) this kernel keeps Big cores always at high freq and always %20 usage(even when I am not touching the screen)

when on NX, little cores are utilized and big cores are left with lowest freq till I touch the screen. Then they fire up (even then they are not top speed). And there is litte to no usage when I dont touch the screen. Dunno what can be the problem.
[Samsung Galaxy S8 & S8+ Cross Device Development] spezl:
Seems not Kernel related. I use _Alexndr's DevBase latest and don't have such a behaviour. All settings are stock... maybe in your case rom and kernel do not match?
[Samsung Galaxy S8 & S8+ Cross Device Development] parser:
That is also what I am wondering, dev can maybe help there...

is there a script to clean delete kernels before flashing new ones?
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
I don't know, always thought that was normal... Does this happen on any other kernels (not NX)?

No. The kernel installer will override the ramdisk, which cleans up scripts from any decent kernel.

For the dirty kernels, my installer will clean up the files I know of.
[Samsung Galaxy S8 & S8+ Cross Device Development] parser:
Didn't try any other kernels actually, was planning to Clean flash the Rom 2night and give it a try directly with your kernel. If it works out, gonna let u know!

Thanx for your response mate!

edit: After a clean install, i am able to get better performance now! everything is fine :)

I am also curious about this mura effects though. I checked that kernels thread but didnt understand what it really looks like. Googled it but long explanations doesnt help, I think I need side by side comparison :D
[Samsung Galaxy S8 & S8+ Cross Device Development] parser:
This kernel doesn't work good with renovate ice rom. At least for me. Dunno why but battery consumption is high, phone doesn't perform as good as nx. But stand by is better. Any1 using this with renovate ice?
[Samsung Galaxy S8 & S8+ Cross Device Development] ayyyy lmao:
Me, and I agree with you. I've used this kernel with googlewiz ROM and battery was great, switched to renovate and battery life took a big hit when using this kernel. At first I thought it was the ROM, but when I switched back to NX, battery life was normal once again.
[Samsung Galaxy S8 & S8+ Cross Device Development] Near_07:
thank you :) . last month i sat my screen and got green and violet tints when brightness is lowered to less than 30%. after flashing the kernel. its gone :eek: . amazing work
[Samsung Galaxy S8 & S8+ Cross Device Development] parser:
[MENTION=7291478]kdrag0n[/MENTION] after some investigation, I think your kernel has some problem directly with V4A. Somethimes I dont know why or how it turns media.codec service on and afterwards big cores and small cores get %20 usage non stop. After I shut down media.codec service it turn back to normal.

If any help there are lags in V4A ui also. When I turn a knob, they wont turn smootly. These things doesnt happen on NX kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] 3arthur6:
Hi,

First great and very complete kernel! Thanks a lot!!

I notice an issue too, "android system" seems to drain more battery than other kernel I tested. But not obvious impact in battery life.

In my logcat, I can see with big redundancy (every 10 seconds) an knox related error as you can see in my screenshot.

Hope it can help for the future.

I use the last r10 release.
[Samsung Galaxy S8 & S8+ Cross Device Development] dmartuniac:
Great kernel ! 6-7H of SoT, when regularly i got 5h with other kernels.

Anyway, after i scrolled down a bit on n8 pages, i saw that the kernels overthere suport 2.81GHz overclock. It is possible to bring those freqs in our S8's?
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:

It's not worth the battery. 2.652 GHz is enough.

and what's the differences between two modes before flashing , thx
[Samsung Galaxy S8 & S8+ Cross Device Development] dmartuniac:
You'll need an unlocked bootloader and twrp as recovery. This kernel comes with magisk root method, so you don't need anything else.

[Samsung Galaxy S8 & S8+ Cross Device Development] loris100:
I dont think running the cpu at 2.81 GHz would kill the battery as you say (screen is the main factor on battery usage) so if you can add those few more frequencies it would be appreciated:fingers-crossed:
[Samsung Galaxy S8 & S8+ Cross Device Development] kdrag0n:
Yes, if it's stable I'll release it along with plenty of other new goodies in a day or two.
