[KERNEL]SM-T357T - Permissive

[hightech316]

Boots up, not much testing done by me. My 3 year old won't let go of his tab A
Permissive Kernel, Root restrictions removed. Pretty much stock ( For now ) .

Built from SM-T357T_NA_LL_Opensource.zip found at http://opensource.samsung.com/ using Uber tool chain .

Will add more info, github links, and thanks later. Also a TWRP installation script , for now use download mode and Odin.

This worked for me, incase it does not work for you I suggest taking a backup of kernel prior to flashing .

Running 5.0.2 , so I did not have to check OEM unlock
BASEBAND T357TUVS1PL1


You flash this at your own risk. Please ensure you have the stock ROM and OR KERNEL to hand downloaded from SAMMOBILE in case of problems. This will trip the knox counter.

Hopefully can get an updated build by the weekend few releases until I get the hang of changing changing CPU freq & scaling .

Also looking into ROM dev... Anyone want to jump in and help the T357T out, more the merrier . We don't have much for this particular variant , hopefully we can change that around!:highfive:

I've poked around a while ago, but never got deep into it. Maybe I'll fire up a Linux stick and see what happens. I'm on the newest baseband so I couldn't use your kernel, but i just rooted and after installing adaway and removing some bloat via titanium backup, I noticed a huge drop in overall lag and I can actually use the tab without getting annoyed.

Could you post up a list of what you safely disabled?

Using titanium backup ( and being rooted ) , you can freeze knox and other carrier bloat. ( 2nd link shows which apps )

Here is a small guide how to debloat via windows , good read :good:

https://www.xda-developers.com/uninstall-carrier-oem-bloatware-without-root-access/

Also check out this post. A list for the S7, of which apps are " safe " to remove. I'd proceed with caution . Alot of these apps won't be seen on our Tab A. Still, good reference .

https://forum.xda-developers.com/galaxy-s7/how-to/debloat-galaxy-s7-services-safe-to-t3432967 .

Further down the line I want to release a debloated / optimize ROM.

I'm currently stuck building v2 (CPU Governors, I/O schedulers, TCPA, Init.d , etc) of this kernel.

Compile errors of course . Slowly, but surely I'm fixing them.

Thanks for compiling this permissive kernel but it is not flashing under the same OS you used. I tried all versions of Odin and it gave me an Unsupport dev_type error. Can you confirm the baseband version you used? I checked on samsungmobile and I think you forgot the A in the basband version (APL1). What steps did you use to flash the device? Thanks again -AC

Use odin 3.12.x

I can't flash either, I get the same error Unsupport dev_type error, my baseband version is also APL1, any way of helping us out with this issue? or maybe make it flash-able through TWRP?
Thanks!!!

Well, this was fairly anticlimactic
