SuperSU v2.79 SR1
Posted on 2016-12-22, 35 comments, 363 +1's, imported from Google+/Chainfire

NOTICE: This content was originally posted to Google+, then imported here. Some formatting may be lost, links may be dead, and images may be missing.

This update focuses primarily on SELinux changes for Nougat:

  • SuperSU will now use it's own 'u:r:supersu:s0' context to run in, rather than reusing the 'u:r:init:s0' context. This can prevent some conflicts from occurring, but it may also cause some root apps (or complete firmwares) to suddenly stop working. Please report these in the BETA thread on XDA. In time this feature may be ported back to Marshmallow as well.

  • SuperSU no longer modifies file_contexts[.bin]. This modifications caused issues on some firmwares, though why this happens exactly has not been identified. Regardless, it has been refactored away.

On app-heavy devices SuperSU may have been slow to grant root access, especially right after boot, when the device is very busy, or when it needs to popup a confirmation dialog. This should now be much better on Nougat firmwares, where the problem was most apparent. It has also improved for older firmwares, but not as dramatically - it will take some more work to backport the full patch.

Compatibility with the latest TWRP on the PIxel has also been fixed, and various other small changes are listed in the changelogs below.

CF-Auto-Roots have been needing updates for a while now, but it will have to wait some more, as I'm trying to push a FlashFire update out first. For the devs among you, I have slightly updated the How-To SU docs.

+René Bour delete the system partition, flash Rom then root.

Chris Jole7 commented on 2016-12-22 at 23:11:

Thanks for the update did you take a look about the OnePlus 3 problem intalling Super SU when on F2FS?

Düdmæng Brøssøvítçh commented on 2016-12-22 at 23:14:

+René Bour​ Marshmallow? So you're running a ROM? If you're running a ROM like CM don't use SuperSU it won't boot! LOLOLOLOLOLOLOLOL! It may work fine if you remove both SU binaries from the system.

René Bour commented on 2016-12-22 at 23:14:

+Linux Rox Haha… Thx, but i'm not at home until 29.12. I can't Flash everything, my wife kill me…. :(

René Bour commented on 2016-12-22 at 23:16:

+Düdmæng Brøssøvítçh​​​​ NO is original Samsung ROM… lololol idiot…

and SuperSU runs perfect since years until original 2.79.

Düdmæng Brøssøvítçh commented on 2016-12-22 at 23:20:

+René Bour I was completely unaware that even existed! I flashed CM13 on mine because I thought Samsuck dropped support for it! Jeeze. Sorry. Also, I have noticed some Stock ROMs don't like to boot fresh with SuperSU. Maybe try booting first then after setup is done try flashing? Dunno, good luck to you though. Maybe XDA can help you out?

René Bour commented on 2016-12-22 at 23:25:

+Düdmæng Brøssøvítçh​​​​​​ Ok, your sorry is accepted. I test the new 2.79 SR1 on my own device (S5) and it runs perfect. Second I install it on my wife's S4 and the device hangs at boot. (BOTH original Firmware) Gives a chance to "repair" without any PC equipment? (No flashing from a PC is possible at this time, but the TRWP recovery is available.) 

René Bour commented on 2016-12-23 at 01:30:

Problem solved...

Installed "old" 2.79 from SD-Card via TWRP and the Device (S4) boot again...

uff... I think will be alive the next days.... ?

... But this 2.79 SR1 is crap for Galaxy S4 (original ROM). ?

Zygote dies with 2.79 SR1, xposed .87 installed, socket permission denial resulting in boot loop on emotion 6.0.1...posting on xda also

Jens Meier commented on 2016-12-24 at 23:36:

There is a little glitch in the su gui. When changing from log tab to settings tab and switching back to log tab, the icons for refresh and clear log are gone. The only way to get them back is restarting the app. Thank you for all the efforts you are putting in maintaining and improving this essential tool! Really appreciate it.

unonice commented on 2016-12-25 at 01:15:

+Kjell O . . When in doubt , use the Play Store .. ???? I bought the paid version ..

+Tayeb CW maybe

Matt LaMotte commented on 2016-12-29 at 22:58:

I know in the beginning, this process needed to be done from Fastboot but now in the newer updates I only see the Flashable ZIP. I hadn't read anywhere the process changed but can I assume the process has changed? I just need to boot into bootloader, then recovery mode and flash this??? Thanks in advance!

Danee bee commented on 2016-12-31 at 10:53:

thanks for the update,

Andrew Rardon commented on 2017-01-01 at 16:12:

Got lucky and picked up a 7.1 Pixel from VZ yesterday, new TWRP and SuperSU installed per instructions without hitch. Thanks for all the hard work, happy 2017.
