There is no dex support,right? If i buy the dex pad will it work?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Kernel support is there in stock kernel, DeX isn't available just in system, so you need a Note8 port or a port from another device with DeX to work. With this kernel you don't need DeX Dock since there's an hax that launchs DeX mode with whatever hdmi adapter/dock

[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] haniasita:
Hey there, I've been having issues installing your kernel on my European A530F A8. I've managed to extract two crash logs when trying to boot version 2.1, I hope they'll be any help - And if not, I'm more than willing to cooperate in finding out what's going on.

Version 1.0 of your kernel boots fine, and my phone is currently using it, but as you can expect from previous feedback, MTP doesn't work at all on it, hence why I'm trying to install 2.1.

Version 2.0 booted the first time it was flashed, but wouldn't anymore after rebooting (Using the normal reboot button) or even after being re-flashed.

The two attached logs are from version 2.1. The phone starts up, shows the "Samsung Galaxy A8 powered by Android" screen, and... Doesn't do anything else, since the crash occurs 0.12 seconds in. Again, I hope this is any useful.

Crash 1 (Line 195)

Crash 2 (Line 231)

EDIT 1 : From my understanding, this could be due to one of the drivers crashing, and bringing the entire kernel down along with him. If that were the case, is there anything I can do to try and pinpoint which one? Ever since receiving it, this device has seemed to behave below expectations, so I'm not saying it definitely is, but it might be an isolated case - And in that case, I'd rather not waste your time, I'm already thankful for your work so far. It might not be related, but this device is running the PRO (Proximus, Belgium) firmware, and there is no RMM lock whatsoever, the entire function seems to be deactivated on devices running this firmware (There's no listing for it in Download Mode, either). If you've done some wizardry related to that, it might be something to look into.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] stfn74:
Will this kernel work on the Canadian version SM-A530W?

I was able to install TWRP 3.2.1-1, RMM-State_Bypass patch and root using SuperSU and those worked just fine...
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Kernel zip checks model number prop so zip dont flash dirrctly the kernel. You can try to flash it manually via Twrp (extract "jackpotlte" file from zip, rename it to "boot.img", and in TWRP select Install>Install Image>Select the kernel .img>Boot>Swipe to flash>Reboot). Anyway Idk if it's gonna work since can variant has separated dts files, backup your current kernel in TWRP just in case
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] stfn74:
Well, it did not work :) I was able to flash it following your instructions, however upon reboot, it apparently hang/froze on "Samsung Galaxy A8, Powered by Android" screen. I waited maybe 15-20 min - no change.

The only way to take it out of this mode was to press and hold VolUp+VolDown+Power until it rebooted, at which point I pressed VolUp+Power to enter TWRP. Tried deleting Dalvik/cache and reboot - same story. Finally restored boot partition from backup and it rebooted normally.

Happy to help making this kernel work for SM-A530W, if you're willing to spend time on this...
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Did you flashed v2/v2.1? If yes try v1 since v2 and v2.1 have boot issues for all the variants
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] stfn74:
So the behaviour above was with v2.1. I tried v2 - same thing. v1 however seem to work fine. The only issue I noticed so far was that it had forgotten my WIFI connection, had to re-enter the password.

Two questions:

- as you said, I renamed jackpotlte to boot.img. But I also noticed other files, like jackpot2lte and jackpotlteks. What are those, should I try with one of them?

- the change log says the v2.1 is based on A530FXXU2ARD1. My phone runs on A530WVLS1ARD1, but apparently I can upgrade to A530WVLU1ARD2 using this and Odin. If I do that, will it make a difference?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Wifi bug is there because fixed secure storage libs hasn't been extracted in your current ROM (and since you didn't flashed the kernel zip but installed it manually, that's normal lol). Regarding your questions:

1. No since jackpot2 is A8+ (A730F) and ks variant is korean A8 (A530N)

2. No, and I don't see why it should lol
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] stfn74:
Thanks for the explanations. Having to reconnect to wifi every reboot is a hassle as I am frequently rebooting these days fiddling with my new phone. I guess I'll wait until hopefully you can incorporate A530W support in the kernel. Again, happy to test for you...
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
I'm gonna update the kernel probably when Oreo is out (highly probably at the end of June or end of July) and when I'm gonna finally get my hands on this phone since I'm planning a ROM too for it
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] 587.saboor:
I have the same model as you and i couldnt install twrp, can you tell me how you flashed twrp on ur phone?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] mchlbenner:
Did you check it in development in setting?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] 587.saboor:
nvm i figured what i did wrong

i didnt flash the boot patch
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] mchlbenner:
When you do it next time use custom v1 kernel.

[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] ccom2k1:
Will work this kernel with Android 8?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Of course not, since it's N source based. But I've already requested O source code at OSRC, so as soon sources are out, kernel will be updated.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
So decided to update OP with latests info about MCK Oreo kernel (many people still didn't saw it up in github), also removed faulty v2/v2.1 versions. Final version with upstream will get released once I've got free time to work on the kernel. For now that's all, enjoy!
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] riesandyfr27:
can i root oreo with mck now?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
That bug is kernel related ("init" patched file in ramdisk) but there's nothing I can do about it since it's Magisk related. I've already reported the bug, so all we need to do now is wait for a fixed version of Magisk
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] mchlbenner:
So is this not a Samsung root or is it magisk issue?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] shunsai:
I've come across several different modified Magisk versions in the S9 threads that I'm considering trying.

No one seems to know what the modifications are, but they allowed root on S9 Oreo. I figure it couldn't hurt to try on A8.

Have you tried any modified Magisk version yet?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Read again what I wrote?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
I still don't own the phone so didn't tested on my side, but my testers tested just topjohnwu official zips. You could give a try to those zips, I heard S9 had issues too with "init" file patches
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] 587.saboor:
Wait what i wanna test the zips

https://mega.nz/#!ec9zkDIA!w8Q77oIZAUgKUSePDmTsVBwfTKjU8C81WGdCgIUnQvM
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] shunsai:
Sounds promising. I read elsewhere that Magisk's creator (topjohnwu) is in the military, so there's no telling if or when his schedule would allow him to address the bug for our phone, so for now maybe jesec's modified Magisk is the best bet for A8. I'll be away from my main computer till later next week, so won't have a chance to try out the modified Magisk versions I found until then. Perhaps others will beat me to it and post their results.

Let us know how it goes!
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Still didn't flashed TWRP?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] shunsai:
Nope, not yet. Hehe. Not until next week when I get back. :o
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] 587.saboor:
Holy crap it worked
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] shunsai:
Great news! Thanks for reporting back. Mind posting about it here so we can start aggregating results and spreading the word?

Actually no, false alarm, forgot to download magisk manager, looks like it failed to flash but it didnt show in twrp
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] WilliamJ123:
i try to flash this, but at reboot the sim work but magisk manager says that magisk isn't installed
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] 587.saboor:
Yep, check the post right above yours

Currently we are struggling to find the actual answer to that problem
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Proud to announce the release of MCK stable v1. A lot of new things has been added to this version: from upstream to Magisk baseband loss fix. Give an eye to the changelog and let me know how's your experience with this new version. Enjoy!

Hi

IIs it possible to do support camera2api with Raw? On Note 8 Exynos Raw is working.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Of course not. A8 cam hal/hw isn't that advanced
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] shunsai:
Since this kernel disables security related features such as TIMA, RKP, KAP, DMVerity etc, is it still necessary to flash no-verity-opt-encrypt and RMM Bypass zip? From what I understand it won't hurt to flash them, but I'm just curious.

Also, at what point in the rooting process is it best to flash this kernel?

OEM unlock via Developer's options.

Restart in download mode (Power + Vol ↑ + Vol ↓)

Install TWRP recovery via Odin (make sure auto reboot is off).

Reboot to recovery (Power + Vol ↑).

Wipe data and again reboot to recovery.

Flash MCK (?)

Flash no-verity-opt-encrypt and RMM Bypass zip (just to be safe)

Flash Magisk 16.7 and reboot to system.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
No, it's not necessary. MCK has already RMM State Bypass inside (both zip and ramdisk; this means you don't need to flash my RMM zip everytime you change the rom if you use my kernel) and patched fstab with disabled DmVerity and Force Encrypt
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] WilliamJ123:
Problem sim

Yesterday i've installed the kernel and other stuff, and today i reboot the phone and it says there isn't the sim, i try to reflash the kernel but nothing, but yesterday i've reboot the phno many time and it wasn't happenend, now i try to follow the guide to install, and i'm waiting for the re-download of oreo

yesterday i've installed also xposed 90.2 beta 3 and samsung good lock 2018
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Don't use Xposed... There still isn't a custom build compatible with Samsung firmwares so forget to use Xposed for now
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] shunsai:
I haven't tried it out on the A8 yet, but Xposed worked fine for me on my stock rooted Nougat A5 (2016). I know things have changed in Samsung's security techniques in the last couple years, but I don't recall ever using a custom Xposed on my Samsung phones. I'd be interested to hear others' experiences.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Actually people always used to flash Custom Xposed Build by Wanam on Samsungs since that's optimized and coded to work on Samsung ART libs (yeah it's not a "security technique" that blocks Xposed to work properly); those new builds for Nougat/Oreo causes lots of different issues on each different Sammy phone with TW/SE ROMs (from who experiences simple lags to people like you that got not working baseband). Of course I'm no one to tell you what to flash and what you musn't flash on your device, just stating out the issues you could and can get by flashing a tool that hasn't been made for the firmware you're using, expecially because you're asking help about an issue that isn't caused from this kernel
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] WilliamJ123:
with xposed 90 beta 3 it work without any problem, instead with xposed 90.2 beta 3 after 1 or 2 reboot the sim disapear
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] shunsai:
I appreciate the quick response. But I think some of that was meant for [MENTION=6781156]WilliamJ123[/MENTION] (he was the one who had problems with his baseband). Good to know anyway!
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Yeah, sorry for the misreading lol
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] wirespot:
With V1 and following Shunsai's procedure (see post above):

What works:

* MTP is working (popup "allow PC connection" shows up on ever USB connect and you can access phone storage and SD card from PC)

* Baseband is still there.

* I can enter developer settings without Settings app crashing.

* Magisk (16.7, with Manager 5.8.3) shows as installed.

* Root Checker pops up root request and reports that root works fine.

* Termux can get root with `su`.

* Titanium Backup works.

* Installing Xposed (regular version, not systemless) from Magisk does not break baseband. Xposed modules like Greenify and GravityBox are working.

What doesn't:

* ADB won't connect. I don't get the authorize device popup. I am also missing "revoke ADB authorizations" in the developer menu. Device shows up as "offline" on PC. I've tried turning ADB debugging on/off, rebooting, resetting keys on PC. The /data/misc/adb/ dir on device is empty (no adb_keys file).

* Cannot check SafetyNet, Magisk Manager always says "response invalid".
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
1. Try to copy your adb_keys file (Windows: X:\Users\yourusername\.android\adbkey.pub; Linux: /home/yourusername/.android/adbkey.pub) inside /data/misc/adb folder with 0755 perm via TWRP and reboot to system. Kernel has adb offline fix inside so no idea why it has that behaviour.

2. It's a Magisk Manager app issue. Know more about it here
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] wirespot:
An alternative way of checking for SafetyNet is to search Google Play for an app that uses it, like Netflix. If you have installed a Magisk module that breaks it, like Xposed Framework (even if it's not activated), you won't get Netflix in the results, and if you go to its page manually it will say it's not compatible with your device.

After installing and uninstalling a bunch of stuff, I'm experiencing lots of freezes and spontaneous reboots. Anybody else noticed this?

Could this be caused by Kernel Adiutor? The problems seem to have started around the time I installed it. I haven't modified any kernel params, just installed Adiutor, took a look around, then uninstalled it. Could it be modifying something on its own, by default?

Stuff I installed and uninstalled (note that this is part of the stuff I install for testing all the time, it hasn't caused issues on stock kernel):

* Magisk: Xposed (system).

* Magisk: Xposed (systemless SDK26).

* Xposed: GravityBox O[reo]. I just change the statusbar font color on/off to check it's working, I don't use any other settings.

* Xposed: UnifiedNlp module.

* Root apps: Root Checker, Termux, Titanium, F-Droid, UnifiedNlp Manager app.

I will retry a fresh install from scratch (reflash everything stock, TWRP, Kv1, test, Magisk, test, then start slowly adding stuff one at a time) and try to see if I can pinpoint the moment it goes wrong.

Question: would an eventual LineageOS release for this device use the things we learn/patches from this kernel, or approach everything from scratch?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Nope. Future AOSP kernel will be based off my repo
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] andersonvs:
People, good afternoon

Worth it? Does it really worth it? Because I dont like very much my battery. I had a Moto Z Play (1st gen) and my A8 is so jealous about his battery so anyone have any information about stock kernel vs this custom kernel mainly in the battery drain/battery life improvement?

Thank you so much!
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
People atm are just reporting some lags while Waking-Up from Doze but I figured out it's related to underclock. Gonna update the kernel once I'm back from vacations, yesterday I had the time to just revert underclock and merge new 4.4.148 linux update in MCK branch lol
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] andersonvs:
Nice. But how about the battery? I dont know but yeah, my phone drains a lot and also dont have a lot of "screen awake" time. Nothing compared to my old moto z play and every review I see about A8 2018 says that battery it's the big winner in this phone but I cant see that......

thank u again bro

[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
My tester actually tested on A730F fw in his A530W and said all works correctly. If you're using a custom Oreo ROM it may be caused by bad deodexed firmware
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Pipsname:
I am on 7.1.1. All I did was root via your other thread and have magisk installed.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
7.1.1 kernel was released when A530W wasn't still out so it may give some issue on your variant (ex. Touchscreen not working caused by missing can touch firmwares in kernel)
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Pipsname:
Looking around here I did not see a thread for this setup. Is there a guide your tester used? I would hate to Google around use something you don't really support.

All he did was just flashing A530F AP and HOME_CSC tar on his phone and then just followed the guide in my TWRP thread and once he got all setup he flashed MCK v1.1
