The files listed in the (edited-looking) screenshots show a date of 2013. That could be for ICS, JB, or KK (4.0/4.2/4.4)... i dont know if the methods would work against marshmallow.

Looking at the listing here: http://search.4shared.com/q/CCAD/1/Poot-debug(W100) there is a file posted 7 days ago (which is when that article was posted)...

Dunno. I may download the apk, extract it, and see if there is any obvious stuff in there that wont work (really old versions of SupoerSu, busybox, etc)... not anytime soon, but hey... its something. *shrug*. thanks for the link.

Thanks for trying it though.

I think we can try submitting boot.img to chainfire so he can update cf.autoroot... that's another avenue to persue. How to get the IMG though with out custom recovery or root, plus Knox is the tricky part. More internet searching yay.

King Root App says root available

Two days ago, KingRoot app started to say a new root strategy available but did not work after many attempts. If anyone could root this device. I would desperately asks his help. :crying:
[Android Q&A, Help & Troubleshooting] grandpajiver:
According to chain fire, AT&T locks bootloader's. No unlocked bootloader, no auto root.

In stock download or recovery mode you can side load apks... And for can be mounted [probably not rw].

But maybe side loading systeless root apk may work. Probably not but it's maybe worth a shot? I may try that... Pretty sure something bad will happen.. or nothing.

I really want it so I can kill the 2-3 gigs of bloat and get xposed + obb on sd installed. My daughter has games, some of which lets her move to external storage, some don't. Stupid samsung not letting users format the external sd card into a contiguous file system. Grrrr

There was a ZTE phone available too. I'm sure that one is rootable ah well.

[Android Q&A, Help & Troubleshooting] ashyx:
If this device is Samsung, ATT and running Marshmallow then forget all about root and ever getting custom recovery.

ATT lock bootloaders, the Samsung bootloader is unlockable and unhackable.

Kingroot will probably be the only way to root this device if they ever find an exploit in MM.

At the moment there is nothing.

Even a custom debloated system.img will probably be out of the question due to DM-VERITY.

The best you can do is use Package disabler Pro. This can disable all the bloat without root.

[Android Q&A, Help & Troubleshooting] ashyx:
Which firmware build is this device running at the moment, has it had an update yet?

Would you be prepared to test flash a modified recovery image if I provide you with the stock recovery in case it fails to flash?

In the zip below are 2 ODIN flashable files:

sm-j120a_mod_recovery.tar - This is the modified recovery

sm-j120a_stock_recovery.tar - This is the stock recovery

J120AUCU1APC8_ Android 6.0.1.zip

Its likely that the modified recovery won't flash at all and will get rejected by ODIN. However if it does let me know if it boots to recovery.

You will need to disable Auto-reboot in ODIN then immediately boot to recovery after flashing with ODIN when it gives the green PASS.

To manually reboot Hold POWER + HOME + VOL DOWN as soon as the screen goes blank quickly change to VOL UP whilst still holding the other buttons.

Ensure OEM UNLOCK is enabled in Developer settings before proceeding.

Look out for any warnings presented on the download screen when flashing and make a note.

Apparently I have managed to obtain the engineering bootloader and kernel for this device. I also have the firmware.

I don't own this device myself, but if someone is willing to risk their device and flash the engineering sboot it should allow an unsigned recovery to flash without tripping knox.

To test this I would simply unpack then repack the stock recovery to remove the signature.

If the bootloader actually flashes then so should the recovery.

If it does then so should custom recovery meaning supersu could be flashed to gain root.

However this isn't without risk and I won't hold any responsibility if someone wishes to take this risk.

It may be safer to just flash the engineering kernel and not touch the bootloader.

[Android Q&A, Help & Troubleshooting] ashyx:
The bootloader version is correct, your original version APC8 and after flashing APC1.The FA stands for Factory binary and 60 for Android 6.0.As long as the device boots it's fine.

It may be we can't get a root shell, but may still be able to mount system writable with these images.

Looking at Chainfire's script it remounts the system partition writable.

Have you tried running the root script yet? Just try it no harm can come.

If that doesn't work then a couple of things could be tried.

One is pre-root the system.img, if samsungs engineering boot image doesn't have rooting restrictions then it may boot.

Second, if the Sboot does allow an unsigned recovery to be flashed then root could be obtained that way. To test this I will repack the stock recovery to remove the signature and then see if it flashes.

By the way are you able to set Permissive mode? This was possible with an engineering boot I gave to another member for the S550tl, which means that selinux isn't being forced.

Below are the stock and repacked APC1 recovery images.
