Oct 8 software update

I just got a software update to 5.1.1 on my new Galaxy tab S2 with a number of fixes. I wanted to verify that the permissive kernel you provided is the same as the kernel in the October 8 build. The kernel version shows:

3.10.9-5971344

dpi@SWHD4416 #1

Thu Oct 8 14:38:55 2015.

Is it safe to flash your permissive kernel over this one? Thank you very much, and thanks for bringing Root to the S2!

[Galaxy Tab S2 Android Development] ashyx:
It's BOH7.
[Galaxy Tab S2 Android Development] crcowan:
Any chance of BOJ1?

Thank you - I take that as a no. Is there any chance of a permissive kernel for BOJ1? I had noted one of the fixes is related to "overheating" which sounds like something that is important.

I really appreciate all your work.
[Galaxy Tab S2 Android Development] ashyx:
BOH7 is the latest source release by Samsung.
[Galaxy Tab S2 Android Development] crcowan:
ashyx:

Ok - thank you. I guess we can just hope they release the source soon.
[Galaxy Tab S2 Android Development] ashyx:
You can still use the kernel. Just make a backup of the current one in case it doesn't boot.

Likely hood is it will.
[Galaxy Tab S2 Android Development] crcowan:
ashyx:

Thanks so much! I can confirm that it worked just fine on my 710, BOJ1. I suspect it would be safest to re-flash the BOJ1 kernel if/when Sammy releases it (and you make it permissive). But for now this is terrific.

You have done an outstanding job.

UPDATE: I found out that it was the PC USB port problem, so I changed USB port when the tablet was on, and then it reinstalled the drivers, so I thought I'd give a try on Odin again, and boom shakalaka, it worked, then I was able to flash smt810_cf_autoroot, tablet T810 rooted.

Thanks a lot, never quit bro!

Please any help!!!

I was able to flash the kernel t810_5.1.1_boot via Odin v3.10.7 and the tablet restart and is fully functional...

but when I went back to download mode to flash smt810_cf_autoroot on Odin it does not recognize the device anymore, it does not show device added as before, any idea of what can be done?

I was trying to root with Android 5.1.1 on it.

I hope someone can advise asap, many tks in advance.
[Galaxy Tab S2 Android Development] ashyx:
I

Put it in download mode THEN plug in the usb cable.

If the drivers don't auto install go into device manager and update the driver. It should then install.
[Galaxy Tab S2 Android Development] crestfallen:
just wanna confirm, would this work on T715Y?
[Galaxy Tab S2 Android Development] diehard2013:
What to flash first: TWRP 2.8.7.2 or the permissive 5.11 kernel?.

final destination is Root.

The permissive kernel seems to be required for root and TWRP install. The only problem with that is setting permissive mode breaks Netflix on the newer versions of the app due to DRM updates. This can temporarily be bypassed by renaming /system/lib/liboemcrypt.so, but that's not an elegant solution and it can break other apps.
[Galaxy Tab S2 Android Development] workdowg:
Really? All my devices use permissive kernels (nexus 9 marshmallow included) and all use up to date Netflix... Maybe your country is not US?
[Galaxy Tab S2 Android Development] skawtnyc:
No, I'm in the US. It's definitely the kernel, and definitely Samsung/Touchwiz devices. This has actually been diagnosed elsewhere. I don't have this problem on non-Samsung devices, such as my Nexus 5x, which is rooted, has a custom kernel and TWRP installed.

[Galaxy Tab S2 Android Development] skawtnyc:
I don't know why it's working for you, however this isn't an isolated incident as other people are experiencing it as well. Try updating your version of Netflix (the latest one in the play store is 4.2.0, not 4.1.0 which you have installed.)

Edit: Sorry, my bad, 4.1.0 is the latest. I still don't know why it's not broken for you. I do know that renaming liboemcrypto.so resolves the issue immediately. But that could possibly break other apps.

[Galaxy Tab S2 Android Development] semakawa:
You can delete the file liboemcrypto.so because no other app will need it.
[Galaxy Tab S2 Android Development] skawtnyc:
I was under the impression that it was used by Touchwiz for DRM. I'll keep it renamed *.bak, just in case I do come across an app that requires it. Maybe someday we'll have a stable version of CM for this tablet and it will no longer be an issue.

[Galaxy Tab S2 Android Development] Lakino:
Hi ashyx, I've pressed the thanks button and would like to publicly thank you for your efforts. Hope you stick around and continue to develop for the Galaxy Tab S2. I empathize with both your frustrations and annoyances of newbies asking the same questions over and over again AND with the newbies' own frustrations of feeling completely overwhelmed by the rooting process.

It doesn't help that Samsung has this KNOX counter system that I've never seen before -- coming from mostly pure Nexus devices. It's another added hurdle that confuses newbies even more. So I can understand them wanting to ask questions but I know it can get quite annoying to answer repetitive newbie questions in a development section meant more for experienced tinkers or developers.

Please don't get too put off by the newbies. Everyone was a newbie sometimes in their life. :o

Keep up the good work! Any plans to update this kernel?
[Galaxy Tab S2 Android Development] bsteady2:

Is this an OK1 Kernel or the previous release?

---------- Post added at 03:36 AM ---------- Previous post was at 03:35 AM ----------

Actually I see that it is not its based off the OH7 source.. could you make an OJ1 version of this just to be 1:1 with OJ1? :P

[MENTION=4899305]ashyx[/MENTION] Could you please make a Permissive kernel based on the OJ1 source?

I will pay erm donate. :)
[Galaxy Tab S2 Android Development] ashyx:
OJ4 is available.

I'm not sure if this kernel is of any use to me as it's revision 2 and it may cause issues with earlier U1 devices.

I will use it for my twrp 3.0.0-0 update coming soon, just hope it's backwards compatible with U1.
[Galaxy Tab S2 Android Development] DeeXii:
Well OJ1 is the latest OTA and one that SmartSwitch gives for the T710. So users are bound to be getting it.

Many of these T710 come with OJ1 out of the box.

Could you do it for me if I pay you?

What do you mean U1 devices? I mean I have a T710 it was on U1 but I changed it to a U2 firmware because the OJ1 resolves a heat issue.
[Galaxy Tab S2 Android Development] DeeXii:
[MENTION=4899305]ashyx[/MENTION] There is no OJ4 for the T710...

Are we talking about the same device?

As you can see from Sammobile there is an OJ1 and a OL6...

The OL6 is questionable as it doesnt appear when doing OTA, or SmartSwitch.

OJ1 shows up on OTA, SmartSwitch, and on T710 out of the box.

Your old permissive kernel was based on OH7 I assume.

As you can see OJ1 and OL6 are both U2 kernels.
[Galaxy Tab S2 Android Development] ashyx:
Yep, XXU2AOJ4 source code has been released and should be compatible with OJ1.
[Galaxy Tab S2 Android Development] DeeXii:
Where do you see the source for OJ4? Why would they release a source to something that is no where to be found in the wild?

Also this is what samsungs open source site says...
[Galaxy Tab S2 Android Development] DeeXii:
[MENTION=4899305]ashyx[/MENTION] Found it!

T710XXU2AOJ4: is an old Android 5.0.2 not 5.1.1!

T710XXU2BOJ1 : is a newer Android 5.1.1.

You are confusing two totally different Android versions firmware.

Dont base your twrp 3.0.0-0 update on OJ4 or you will be using a 5.0.2.

There is an even newer firmware called T710XXU2BOL6.

OL6 is the newest release for the T710.

However as I posted on the other thread; it only appears on Sammobile and via Kies.

For some reason it doesnt show on OTA or via SmartSwitch (new reformed version of Kies).

So it makes me wonder if they tried to pull BOL6 but accidentally left in accessible via Kies because you are suppose to use SmartSwitch with the Tab S2.

Or it could be the opposite. Perhaps SmartSwitch is so new they forgot to add it to SmartSwitch..

Either way there is no source released for OL6. I have requested it which I have done literally dozens of times with other kernels.

Usually it takes 1 - 3 weeks for them to release it after I email them a few times.

Since there is no source for OL6 I have been focusing on OJ1.
[Galaxy Tab S2 Android Development] ashyx:
I see, you're right that's a 5.0.2 source. Don't know why I didn't see the A.

If you requested BOL6 3 weeks ago it should be due for release.

I can see BOJ1 is the latest source.
[Galaxy Tab S2 Android Development] ashyx:
I have built your kernel could you upload the OJ1 boot.img and recovery.img

I will post it later.
[Galaxy Tab S2 Android Development] DeeXii:
It wasnt 3 weeks ago...

I requested it last week. I was just pointing out that over the past two years of requesting sources usually they take 1 week to 3 weeks.

I have seen them respond to my emails and post 4 days after a request and also seem them take almost a month.

Fingers crossed lol.

But question: BOL6 and BOJ1 are both U2 and B. So does that mean I can flash OL6 and flash back to OJ1?

Anyways.. I will get you those files you need now.

Will PM..

---------- Post added at 11:44 PM ---------- Previous post was at 11:31 PM ----------

I just PM(d) you a link to the OJ1 files.

Thank you very much by the way!

I really appreciate it! :)
[Galaxy Tab S2 Android Development] ashyx:
I'm aware of how long Samsung take to release source code requests.

I usually give them 10 days then request again.

You should be able to go back to OJ1.

[Galaxy Tab S2 Android Development] ashyx:

[Galaxy Tab S2 Android Development] ashyx:

[Galaxy Tab S2 Android Development] DeeXii:
To be honest I havent tried it yet. I have some family in town and have been occupied..

Let me flash it now...

I didnt realize it needed to be tested.. I always assumed that going permissive was straight forward.

What am I looking for?

Thanks again for doing this! :D
[Galaxy Tab S2 Android Development] ashyx:
Well it at least needs to boot, then check settings for permissive status.

Permissive used to be straight forward on previous 5.1.1 kernels, but not so any more.

Samsung attempt to force it in later kernels.
[Galaxy Tab S2 Android Development] engine95:
Sorry to get this here late but we've had 710/810 Permissive OJ1 kernel out for a while.

The first link, the 810 is a dirty .img because I didn't know it had systemless root. That was fixed in the second link.

Both 710's were good to go.

Of note, while I compiled these as permissive, and it worked as permissive, it killed wifi on reboot. So they were also modified in the ramdisk as permissive. Just an FYI.

Appreciate your great work!
[Galaxy Tab S2 Android Development] DeeXii:
The latest updates are just kernel updates. The base ROM (platform) is the same. So if you flash this older permissive kernel you are literally removing the intended update. To ensure you are using the latest update be sure to run a permissive kernel based on the same source you are running.

e.i. if you are on a PB1 rom get a PB1 kernel. I dont want to hijack this thread in anyway but I do want to help you. If you look around there are some PB1 permissive kernels floating around. ;)

Greetings all,

I've spent 8+ hours almost straight working on my Tab S2 and here is my log of events:

* My

9.7" Tab S2 (SM-T810) WiFi Model

came with LP 5.1.1 (OJ1)

I have....

1. Odin (PB1)

2. Odin TWRP

3. Odin CF Root

4. Odin PB1 Permissive Kernel

I had these issues after Odin'ing the PB1 Permissive Kernel:

1. The Tab would reboot on its own after a few minutes of scrolling around on it.

2. I could not enter Recovery (TWRP) using the button sequence (Power+Home+Power Up). It went straight to the teal screen (Downloading Mode...)

So then I Odin the recommended kernel (although older) in the OP for the 810 Model and...

1. It seems to be staying on fine without rebooting it self at random. HOWEVER...

2. I am still not able to enter recovery (TWRP). It goes straight to the teal screen (Downloading Mode...)

My theory...please correct me if I'm wrong and I hope you do....

1. Because my tab was originally on (OJ1), perhaps it still has some lingering files deep down in the abyss somewhere that are (OJ1) only, which may be causing these strange issues like with the TWRP disappearing and not being able to go into Recovery...did OJ1 leave a foot print behind of some kind to conflict with the PB1 firmware?

2. This would mean that the tab needs to be wiped clean. So should I factory reset first, then Odin (PB1) etc...??

3. Should I reOdin TWRP again and once I'm in there ....is there anything else that I could to do to ensure an absolutely clean start? Wipe Partition? Please include every detail as to what all I should do in TWRP.

Note: I am downloading the PB1 firmware from Sammobile as we speak. The other PB1 firmware file was downloaded from somewhere else, so to ensure that I have the complete OEM file, I've decided to download it from the source.

Questions:

1. Is there any harm in reOdin'ing the firmware over and over again, wiping dalvik/cache in TWRP, factory resetting all the time...etc..? Does it corrupt anything in the system? Wear and tear in a way of any kind? I've always been curious about this....Please confirm....

2. Once we're on Revision 2 firmware like OJ1 and PB1....due to the boot loader, we're not able to roll back to OH7 (Revision 1) firmware? - Though I am seeing people go from OJ1 to OH7 and flashing the custom ROM's that are available for the SM-T810's.... Am I missing something here? Is it possible to roll back to OH7 from OJ1 or PB1? Yes or No? Will the Revision 2 boot loader cause issues on a Revision 1 firmware like OH7?

p.s. Much thanks to [MENTION=2996598]DeeXii[/MENTION] for all the help and support. He's been awesome.
