As you read per instructions in OP, you need to reflash Magisk or SuperSU. Did you even read them? :confused:

That's normal, will only happen if you come from stock kernel to custom kernel. Than it won't loose it anymore

(personally I'm really surprised at the comments popping up everywhere about wifi and bluetooth pairs being lost? Nothing changed from previous years. I wonder if it means that with the S8+ and S8 we have a alot more users who have decided root is the way to go)

Hey bud. After flashing your kernel I'm getting a bug in the Facebook app whereby if you are scrolling through comments on a thread the act of pressing on the screen to scroll continually gets picked up as a touch and hold event (i.e. edit post/copy post etc)

Given I didn't have the bug before flashing I have to assume it relates to changes made in your kernel.

Now interestingly I had exactly the same bug on my OnePlus 3 using AOSP or LOS so there must be a connection in the kernel config.

I'll try and pull a log.

I lose wifi passwords with installing kernel ! And TB don't Reinstall the passwords !

Ok. Thanks. And it's normal that TB can't Reinstall the wifi passwords ? Thanks for all

I have 2 questions :

1. Loosing the passwords is known consequence. But is there any working way to get them restored? TB doesn't work indeed...

2. What happens if one flashes a different kernel (stock or other custom kernel) again after flashing this kernel. I guess you'll loose them every time, right?

So, Is this good news for Samsung Pay users ?

No it isn't read my post here:
Nope. Samsung has fixed this bug from the S7.
And most likely they will patch the s7 soon as well so we won't be able to use it.
On the s7 it was: hmmm kernel gives me no result, I think that means successfull passed.
Pretty stupid [emoji23]

Hey :)
Display driver is kept 100% stock and I haven't seen any problems in scrolling. Wouldn't say that it's related to kernel

It's because we switch off secure storage to false (from true on stock)
You loose it again each time you switch from secure storage true to false and vis a verse. This is mainly the cause from stock to custom not from custom to custom

Seems No.
I was also sorta excited to wipe my device again, and Start from scratch with Magisk and this Kernel. However, My focus was on SamsungPay.
Anyhow knowing tkkg1994 from a long time, This kernel would do better than all other kernels.
Sadly this doesn't work anymore, I assume samsung will patch it also on the s7 soon (sadly)
also shealth doesnt works.can we do anything
It works fine, using it since I got my phone

    Sorry to bother you again about this, but is there an ETA on BatMan Rom? I'm holding off on upgrading to the S8+ 'til the Batman Rom is released and am waiting on tenterhooks for it.
    You're not sorry, otherwise you wouldn't do it, and you've asked twice about ETAs as far as I can see. You surely know that asking for ETAs here is frowned upon, and the dev has stated on more than one occasion that he will do the ROM. What more do you want?

    Buy your S8+ or don't. Making its purchase dependent on the availability or otherwise of a specific ROM is frankly ridiculous.
