[KERNEL][PERMISSIVE]Galaxy Tab S3 - SM-T820/T825 permissive kernel - Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &

This is a permissive kernel for the the SM-T820 and SM-T825.
There is nothing special about this kernel except it will allow permissive mode. Some apps require it so it may be useful to someone.
Features:
◘ Forced Encryption disabled
◘ DM-Verity disabled
◘ Root restrictions removed
◘ NTFS support << To be added
◘ F2FS support << To be aded
◘ Current build is -XXU1AQD6 (It's preferable to be using the same firmware build or your device may not boot. however the kernel is working with firmware XXU1AQDC)
Issues:
◘ WIFI password forgotten after reboot.
NOTE: Due to Forced Encryption being disabled you MUST remove encryption from the data partition by using the FORMAT DATA button in TWRP. (THIS WILL WIPE ALL YOUR DATA!)
For information how to decrypt see the TWRP thread: https://forum.xda-developers.com/ga...recovery-twrp-3-1-0-1-samsung-galaxy-t3581359
Download (Must be flashed with ODIN)
◘ SM-T820: T820_permissive_boot_AQD6.
◘ SM-T825: SM-T825_permissive_boot_AQD6
IMPORTANT: THIS WILL TRIP THE KNOX COUNTER AND I HOLD NO RESPONSIBILTY FOR WHAT HAPPENS IF YOU DECIDE TO FLASH THIS. ITS UP TO YOU TO MAKE A DEVICE BACKUP WITH TWRP OR HAVE THE STOCK FIRMWARE TO HAND!

Please note I don't own this device and spend a lot of my free time bringing these builds for you to use and benefit from.
FEEDBACK IS APPRECIATED PLEASE.
THANKS.

Give me a moment and I'll post the stock kernel for you to flash and you can report the outcome.

You want this flashed like the other ones? over the latest firmware? AP/ODIN?

You just need to download the stock firmware from updato.com and install with latest odin (linked in the op)

Download the latest firmware using 'Samfirm'. With this application, you must enter your device name and your region code (in your case SM-T825 and whatever your region code is) . It will give you a 'zip' with four files to flash.
Flash these four files in the latest version of 'Odin' with your tablet in 'Download' mode.

I thought as much.
OK can you pull the logs with the SYSLOG app on Google play.
Boot with the permissive kernel then connect to wifi (make sure the Neverforget app is disabled)
Post the zip it creates.
I'll see if there's anything to give me a clue.

Tried reading them and burst a blood vessel in my brain, if you can read that you should be working for the government in some capacity. @ashyx

So looking at the logs there is some obvious and expected errors:
Securestorage, this is the root of the problem and seems to be common with custom kernels, the reason we have to bypass secure storage with the build prop edit:

Well Samsung don't provide the code to build the wifi driver with the kernel source if that is what it is referring to, however I'm not sure what it means by 'Synchronized'. If it means kernel version then they should be the same. If it's also referring to the other modules that get built with the kernel I can include them. However I'm not sure that will fix Securestorage.
This does not appear with the stock kernel which should be the same version as the permissive kernel.
Further to this we get some info about the wifi connecting:

To me it seems the wifi config is being loaded, but according to the previous error Secures storage support isn't running, so how is it reading the wpa_supplicant.conf then I ask?
Also notice the text in red says 'Ignored', ignoring the wifi config?, Also 'verified password=0' not sure if this is the issue I would expect it to be 1.
Now for some reason none of this exists in the log for the stock kernel, did you do anything different?
Going off this info there is something I am going to have a look at and try in another kernel compile. The best idea would be to get secure storage working if possible.

@ashyx I didn't do anything different that I know of. Surely that remember password being at 0 is interesting.. Why would it say that

Ok I have recompiled and changed a couple of things. Now because I've changed 2 things, one may negate the other. It all depends how the stock kernel was built.
Give it go,also if you could pull the logs again afterwards.
https://www.androidfilehost.com/?fid=457095661767159394
By the way make sure that the ro.securestorage.support flag is set back to true if it existed.

Thanks to you both, ashyx n Jonathan, had it run back normal.
Will try out root later when am more confident ...lol

My bad, it's got the wrong file name extension. Just change it to tar not rar. Sorry.
