[KERNEL] Stock Touchwiz MDB - SetUID Restriction Removed

mattlgroff · May 10, 2013

I am not responsible for anything you do with your device. Anything you or someone else flashes or modifies on your device or someone else's device is not my fault or responsibility to fix (or break).

What is this?
SGH-M919V_JB_Opensource.zip [MDB Version] compiled with the defconfig grabbed from May 7th OTA - M919UVUAMDL. You can grab the source like I did, from opensource.samsung.com. Defconfig was the only change, since CONFIG_SEC_RESTRICT_SETUID was already commented out from the source linked previously. Modules are also included from this kernel source, same link as previously as well.
Flash this if you want to have a non-SetUID restricted kernel compatible with the May 7th OTA - M919UVUAMDL and you don't want to flash the old boot.img which is done in my root thread.

Instructions

Flash in the Custom Recovery of your choice.
If you aren't already rooted, flash a Root.zip such as SuperuSu by Chainfire or Superuser by Koush.
Reboot and enjoy.

Tested On

M919UVUAMDB
M919UVUAMDL

Be Advised
~~SDCard's using exFat will not work with this kernel.~~
Flasher updated, now will not remove all modules in system, but will just overwrite the ones made by Samsung Open Source. This way you don't need to flash exFat modules separately. You can still do so if you want.
The exFat kernel module is not open source and thus is not included in this. You can flash this to get exFat working if it is not..

Screenshots

Thanks to Shabbypenguin for advice on defconfig and modules. Hope this helps someone, and if it did, use the Thanks button.

This will work if you didn't OTA?

(Please don't quote the entire OP...)

Haven't tested on original firmware, only the OTA. Would be nice to have someone try it out and see.

EDIT: Original firmware now tested.

This is greek to me.

I know you're busy. But could you explain the advantage of having a "non-SetUID restricted kernel" and "don't want to flash the old boot.img"?

"non-SetUID restricted kernel"
Being able to have root on the latest firmware.

"don't want to flash the old boot.img"
You can already root the latest firmware by running the ORIGINAL kernel that came with the phone.

Also, just updated OP tested on original firmware.

It's already overclocked to 1.9 Ghz... I wouldn't be one to push it further.

Nice. This is wonderful. Flashing now. Thank you for the clarification!

Just got my s4 yesterday and have already done the OTA update, sorry if I'm being redundant here but just want to double check the procedure just to make sure I don't have any issues.

Do I root the phone using matt's " [INFO][HOWTO][ROOT] May 7th OTA - M919UVUAMDL" thread and after completion flash this kernel?

Thanks, just want to get it right the first time.

HTC One comes with 1.7 Ghz, I thought ours was overclocked to 1.9?

That's one way to go about it, yes.

I think our processor is slightly different (300 karit) even though they are both called snapdragon 600. I could be wrong.

Regardless, I am not going to be overclocking this device.

Someone else can, but I like the plastic not to melt off the back
