[ROOT] CF-autoroot - Galaxy Tab S2 - SM-T710/T810/T715/T815 [19/9/15]

is it on LMY47X.T810XXU2BOJ1?

Hi @msprenger,

I got mine (T810) too, couple of days back with v5.1.1 on it. Also updated it with the latest build LMY47X.T810XXU2BOJ1 (5.1.1).
Wondering if you were able to root on the latest build that I mentioned. Please let me know.

@ashyx,
I understand I need to use your custom permissive kernel if I want to root the device. I read in one of the posts related with the cf-autoroot/permissive kernel threads that the tar file was not working or broken but then you updated the tar files.

Can you please let me know if the links (for the files mentioned) in the OP for cf-autoroot/permissive kernel threads are the ones that were updated and point to the correct files?

Also, I assume flashing twrp custom recovery and cf-autoroot are independent and can be flashed in any order, please let me know if my understanding is correct.

Hi Sammy users ... Used various android devices for some years but this my first Samsung so please excuse the noob question. Have just taken delivery of an S2 9.7 tab (SM T810 UD model running 5.1.1) and want to use OP's files to install(1)Permissive Kernel(2)CF-Autoroot(3)TWRP Recovery. I'd be grateful if anyone could either agree my proposed steps or point out where I might be wrong.

Firstly I have installed on my laptop latest Samsung USB drivers plus Odin v.3.10.7 and on my tab have gone to settings enabled Developer and USB debugging. Searched all through Developer Settings but could not find any setting to "OEM Unlock" then went to "Lockscreen and Security" and under"Security" found "Find myMobile" but couldn't find any switch to disable it.

This is incidental information which might help.....

Kernel Version 3.10.9-5971344

Build Number LMY47X.T810XXU2BOJ1

I intend to use Odin to flash OP's files in the following order ... firstly Kernel then Autoroot lastly Recovery.

1) In Odin load ... t810_5.1.1_boot.tar ... into "BL" section then flash

2) In Odin load ... t810_cf-autoroot_5.1.1.tar ... into "AP" section then flash

3) In Odin load ... twrp_5.1.1_test2_t810.tar ... into "AP" section then flash

I'm uncertain if I am correct in loading the Kernel file into "BL" and whether I can load both Kernel and Autoroot files and flash them at same time or whether they have to be flashed separately.

If I am heading for disaster hope someone will be good enough to correct me before it's too late! Many thanks.

Of course they have been fixed.
Flash custom kernel then cf_autoroot then twrp.

Yea, I couldn't find the setting either. Not clear to me what the process to get to ROOT & custom recovery.

There is a guide in the first post.
For 5.1.1:
Flash the custom kernel in AP slot of ODIN.
Flash cf_autoroot, again AP slot.
Finally flash TWRP, again AP slot.

Thanks. Just to confirm though, no disable OEM lock in settings?

INFO:
This is a port of CF-autoroot for the Tab S2

Hi ashyx, and again thanks for rooting. I successfully installed CF-autoroot on my SM-T815 with Android 5.0.2 (Firmware T815XXU2AOJ4). Much appreciated! :good:

Edit: I did not had the " Enable OEM unlock" option in developer options, but nevertheless it worked fine.

Cheers,
Mischa

Can you flash back to an earlier firmware? Apparently Samsung have been messing with security policy updates lately causing boot loops for everyone that roots.

hi Ashyx,

any updates to root SM-T815Y ?

Not sure what you mean, Root is already working on T815Y?

You don't need to do anything, it's already been confirmed working on OJ4.
Which android version are you running 5.0.2 or 5.1.1?

My S2 has OTA to OJ4 and i was tried to flash OG6 via odin but failed. Samsung has locked Bootloader from OJ4 and can't downgrade to older firmware.
This why i can't root with your CF auto root because it's for older 5.0.2 firmware.
I need your help on new firmware to root .

If you read the first page you will see there is a 5.1.1 version for t810 which should also work for t815, but you would need to flash a permissive kernel.

I'm on 5.0.2, not 5.1.1 so i can't root because not have permissive kernel for T815Y.
