CF-Auto-Root for GT-I9505 SGS4 LTE (Qualcomm) updated
Posted on 2013-05-21, 35 comments, 133 +1's, imported from Google+/Chainfire

The above-mentioned CF-Auto-Root includes the new version of SuperSU that has been adjusted to work on the new Samsung SGS4 firmwares.

That version of SuperSU has also been tested and found working on the I9500, however unfortunately I have not been able to produce a working CF-Auto-Root for this Exynos SGS4 yet. The final piece of the puzzle that still needs to be fixed is flashing a modified cache.img. So far, I've been unable to produce a modified cache.img that ODIN will flash without errors ... Not sure what is going on here.

Already modified to process to include SEAndroid/SELinux file contexts inside the produced image, but that still doesn't work; nor does creating the image on the phone itself. 

If anyone has any ideas or willing to help (and knows his way around make_ext4fs, making and flashing custom images, etc), it would be most welcome. Remember I don't actually have the I9500 so its hard for me to work with either way.

+jonathan capellan +Mike Hawks For which device? Triangle Away works fine on my I9505 ...

jonathan capellan commented on 2013-05-21 at 17:27:

+Chainfire T-Mobile Galaxy s4 SGH M919

Chainfire commented on 2013-05-21 at 17:37:

+jonathan capellan Interesting, it's Qualcomm based so it should just work like on the I9505 ... are you sure T/A doesn't work ? What does it say/do ?

Michael Thomsen commented on 2013-05-21 at 17:52:

Hi, vacation is history. :-) what do you think when it is possible to use mobile Odin on the gt-i9505? Best regards regards Michael

Joe Bear commented on 2013-05-21 at 17:52:

It shows my current status, counter 7, Binary custom. When I run TA it says its successful and shows everything reset. When I check in settings my device it still shows as custom. When I check in Odin mode it show custom. When I reboot the phone and run TA again, it shows the same counter 7 binary custom. I'm on stock rooted.

Has anyone experienced charging problems after rooting?

Robin Tönniges commented on 2013-05-21 at 18:06:

Hopefully ES Explorer will work soon.

With preerooted ME2 it works but now on Auto-Rooted MDM it wont show root folders.

Chainfire commented on 2013-05-21 at 18:06:

+Mike Hawks Interesting, I've had some similar issues with it, but eventually it stuck. Guess I need to look into it ...

+Michael Thomsen Soon!

Thanks! I know other people in the SGH-M919 XDA forum are hoping for it too. Maybe it has something to do with the update that locked down the kernel.

Marc P. commented on 2013-05-21 at 18:38:

Thanks alot, great work.

Jose Faria commented on 2013-05-21 at 21:36:

+Chainfire I know my way around Ext4fs/odin images. Im willing to give it a try.

Plaztek Jack commented on 2013-05-21 at 23:49:

Only problem (if u can call it that) I have is I check for updates and there's none, but when I restart it says there is ..and it happens too quick to do anything

Plaztek Jack commented on 2013-05-21 at 23:51:

But I'm not worried...ill update when all the kinks and bugs are sorted out, seeing a lot of complaints atm

Derrell Davies commented on 2013-05-22 at 00:23:

Meant to thank you earlier +Chainfire

Love triangle away for my SGH-T889

Hesham Othman commented on 2013-05-22 at 10:14:

Please don't forget sprint galaxy s4

Chainfire commented on 2013-05-22 at 10:31:

+Jose Faria according to some other sources, only the make_ext4fs present on the actual I9500 device will work in making flashable I9500 images. Which is darned odd it'll keep nagging at me until I find out why (and find a solution?)

+Hesham Othman is the bootloader unlocked? What is the model number? You willing to test? Is there a stock firmware available?

Hesham Othman commented on 2013-05-22 at 11:45:

+Chainfire the bootloader is unlocked and the device model is SPH-L720 and yes willing to test and there a stock firmware available.. The MDC firmware can be easily rooted with motochoper root kit but a new ota MDL screws the root as the kernel has been patched with the setuid I believe..

Chainfire commented on 2013-05-22 at 17:18:

+Hesham Othman Try this one: and let me know if it works. Word of warning, if it fails, you may need to reflash entire stock firmware

Hesham Othman commented on 2013-05-22 at 17:23:

+Chainfire right now i'm rooted and on the latest ota MDL... should i unroot? 

Chainfire commented on 2013-05-22 at 17:33:

+Hesham Othman Yes, else you won't know if it worked ;)

Hesham Othman commented on 2013-05-22 at 17:36:

+Chainfire right :-D charging phone and will start the process and report back

otis ellis commented on 2013-05-22 at 18:03:

You're the man. Just rooted a Galaxy S4 last night and installed your SuperSU app. I also paid for the pro version on my Epic 4G Touch. Keep up the good work. 

Chainfire commented on 2013-05-22 at 23:56:

+Hesham Othman any luck ?

Hesham Othman commented on 2013-05-23 at 03:22:

+Chainfire it worked fine :) and i tried on the latest OTA (MDL).. 

Ziggy Winnicki commented on 2013-05-23 at 10:02:

Samuel Chua commented on 2013-05-30 at 01:51:

+Chainfire when are you going to. Are mobile odin pro work with i9505?

Qheis Hashemi commented on 2013-06-27 at 23:24:

Kan de GT-I9505 (XXUAME2) worden geroot met CF-Auto-Root-jflte-jfltexx-gti9505? En ik begreep dat er SuperSU problemen waren?

Jacques Thijsbaert commented on 2013-07-07 at 10:04:

yup. mijne hiermee gedaan. dl supersu daarna vd play store :-)

Michal Stano commented on 2013-08-19 at 00:43:

I had my i9505 encrypted, both device storage and sd card. After rooting, password doesn't work, any idea please?

David Woodhouse commented on 2013-11-13 at 10:05:

+Michal Stano  I have the same problem. After entering the password, I see a brief flash of the green Android as usual, and then the screen just goes black. I have to take the battery out to power cycle it, and can never get it to boot. If I do a factory reset and then try to encrypt it again when it's already rooted, it reboots to try to encrypt the storage but fails, and comes back to the real system still unencrypted. I see you posted that in August — did you ever get any response from +Chainfire ?
