Today I had another hour or so to play with that S4, but unfortunately no closer to root. I want to ...

... stress again, that it seems perfectly possible to run a custom firmware, this is purely about rooting the stock firmware. Disabling SELinux appears to be rather easy, though that in turn causes a lot of crashes in the firmware itself. Haven't really looked into those crashes, or if they're fixable, as we're still having problems simply running su. Again, it does appear that the su protection is not actually related to SELinux but to something else in the kernel. Next try, maybe. Or maybe I'll just wait for having a device in-hand and some kernel sauce :)

Kernel Sauce ;-)

Sure sounds tastier;-)

Olaf Meester commented on 2013-03-19 at 21:18:

Aren't the real brainteasers the most satisfying to solve eventually?

Mike Garcia commented on 2013-03-19 at 21:26:

Looking forward to your solution when you're all done with it, the S4 will be my next phone for sure!  Excellent work as always, thank you!

Thanks for fighting the battle for those of us who can't. Posts like that should include a Paypal Donate link.

+Chainfire keep up your excellent work.

Why not just move over to Sony and the Xperia Z? :D

I'm afraid I won't miss Samsung after I got that one ;P

Joe Philipps commented on 2013-03-19 at 21:59:

Kernel that anything like Vsauce? :-)  Maybe, just maybe, ~~HTC~~ Samsung will release source like they're supposed to under the GPL, and you can look at the SUID/SGID portions of the kernel and/or filesystem(s).

Chainfire commented on 2013-03-19 at 22:05:

+Michael Hebo for funsies? I have a Z. It has it's own set of issues.

Michael Hebo commented on 2013-03-19 at 22:14:

Ohhh, nice. So DSLR Controller will be compatible with it? :)

I haven't tested it with the Z yet. Loved it on my previous Samsung though!

Rooting part is great, but provided devs want to develop custom ROMs on the S4. Cyanogen Mod won't be supporting the S4. I also think the majority that'll buy a S4 would be the normal users who probably never even heard of rooting :/

Jason Gurd commented on 2013-03-19 at 23:03:

The Cyanogen Mod support was cleared up this AM, they haven't said yes or no that was another tech source fueling that rumor.

I admire your Insistence on your work, good luck in rooting the S4 :-)

Kok Wei Koh commented on 2013-03-20 at 11:02:

The thing about you that I admire is the fact that you keep your loyal followers/users updated with your new "ventures". I bet a lot of our S4 purchasing decisions will depend on the eventual outcome of this ;-)

+Paul Roberts I'm sure it's awesome news, but I'm gonna pass when it comes to the S4

Andy Cullis commented on 2013-03-20 at 21:52:

Jason Gurd commented on 2013-03-20 at 23:02:

Can you get a S4 in the US yet? Can't remember if there will be a Verizon version?

Johnny Ward commented on 2013-03-21 at 08:52:

Im ditching my pie'd n4 for the Sammy s4..... Already present ordered (rrg interest with voda uk.)

Greg Baker commented on 2013-03-24 at 17:29:

I cant wait till you figure it out. I definitely want to get one but i already have a  Rooted Note2. I think i might wait on the Note3 instead.

Jason Gurd commented on 2013-03-24 at 17:36:

+Johnny Ward I will be more than happy to take you N4 off your hands.

Greg Baker commented on 2013-03-24 at 17:38:
