Here in canada having no issues at all with the mm build no issues with apps or router issues but then again running wireless ac router. Also had no issues with apps knowing where i am, so definately worth going to the mm roms
[Galaxy Tab S2 General] orionshock:
Just got my S2 a week or so ago.

Got Odin

Got Image

No Root or TWRP

Plug n' Play

....

Worked like a charm, no issues on wifi (5Ghz US), didn't even format the the personal space.
[Galaxy Tab S2 General] skyrkt:
Thank you very much for this! I'm in the US and was becoming extremely tired of waiting for Samsung to update the device, while other parts of the world are beginning to receive the update. The step by step instructions were spot on and helpful, and I had my device up and running on Marshmallow in about 10 minutes. Thanks OP!
[Galaxy Tab S2 General] troyraf:
Does Netflix play in FHD for everyone who's updated with TWRP and root?
[Galaxy Tab S2 General] DigitalMenace:
If you go to the keyboards, it took several minutes for mine, but I believe the Chinese options, such as right to left and keyboard were there. I'll check when I have a chance.

I've had no issues that weren't network related. I DID, however, manage to change my region from UK to US for the ROM, but haven't had time to test if anything is actually affected by this change.

Reverting to Lollipop

I have reverted to lollipop optimal rom from TWRP backup (t710). Everything works fine, except I get fingerprint error: "An error has occurred with the fingerprint sensor. If this message appears repatedly, restart your device." Factory reset or instaling clean optimal rom does not solve this. btw, I get fail error after boot.img in Odin if flashing stock 5.1. And again, if I restore 6.0 from TWRP backup, fingerprints work fine.

Any suggestions? Any thoughts? :)
[Galaxy Tab S2 General] Androbots:
just one more time i want to ask is that will this rom trip any kinds of meter i know its from samsung but i am very scared to do this as my father bought tab for me 2 months ago and if he finds that there is some meter tripped problem i will be no linger able to see my tab again as he is also he concerned about warranty of the new device or any phones or tablets he buys so PLEASE CONFIRM ME will rom void my warranty or trip any thing if i flash this on sm t710 with android 5.1.1 in the us country code XAR????
[Galaxy Tab S2 General] lewmur:
While I'm impatiently waiting for the U.S. version also, your claim that "other parts of the world" are getting the update is a bit of an exaggeration.

Only one fairly small country has received the update for the T710. And one other the one for the T810. It is typical for a limited version to be test released before a general release takes place. That way they aren't faced with an avalanche of complaints before having the bugs cleared up.
[Galaxy Tab S2 General] ianmacd:
No, simply installing stock Samsung firmware will never trip the Knox flag.

However, if you install a custom recovery as part of this process and/or root your device afterwards, you will trip Knox.

What that means for your guarantee in practice depends very much on consumer law in your country.
[Galaxy Tab S2 General] ianmacd:
Most users' impatience stems from the fact that it takes Samsung so long to start rolling out any major new Android release to any of their devices.

Marshmallow was officially released in October 2015 and, some six months later, the roll-out for the S2 Tab has barely begun; and this is still their flagship tablet. Even the S6(E), Samsung's flagship phone at the time Marshmallow was released, had to wait months for it.

Meanwhile, many Nexus users are already running previews and now betas of the next major Android release.

I'm just glad that any version of Marshmallow is available for my T710. I'll happily use the UK firmware until the only slightly different official Dutch release shows up.
[Galaxy Tab S2 General] JustMeToo:
I can't get root. I odined MM with no problem and odined TWRP. Every thing works fine. Installed SuperSU 2.65 and had no root. Installed Beta SuperSU 2.7... and no root either. Am I missing something?
[Galaxy Tab S2 General] riane9:
So I can install this on my tab (HK region) with no problems whatsoever? I'm totally new in rom flashing. Thank you.
[Galaxy Tab S2 General] riane9:
Mine too. Super SU says "There is no su binary installed and supersu cannot install it"

Also on boot screen there is a message saying, Kernel is not Seandroid Enforcing.

Badly need help please. Thanks guys.
[Galaxy Tab S2 General] ianmacd:
Use Odin to flash the latest CF Auto Root for the T710. There have been updates to Samsung's Marshmallow security policy in the last week and you may be affected by that.

I know for sure that this route works, because I used it myself to root my T710 on Friday.
[Galaxy Tab S2 General] riane9:
Are you sure that is it ok to use that even if it is meant for 5.1.1 roms only? What about the message, can you enlighten me what was that about. Thanks

And also, which instruction should I follow? 5.1.1? Do I also need to flash the permisive kernel mentioned in this post?

CF autoroot

EDIT:

OK so I tried it, it got me into bootloop.
[Galaxy Tab S2 General] jaydizman:
I followed the instructions then I installed the latest su.zip not the STABLE I had marshmallow and twrp but seemingly no root even tho su app was installed fine. I downloaded "root checker" from the play store and ran it and sure enough su permission window popped up and I granted permission the app confirmed I had working root. This fixed my issue.

I'm no longer able to see my 5ghz Wi-Fi band only my 2.4ghz does anyone know anything about that? Thanks in advance
[Galaxy Tab S2 General] ianmacd:
There's a CF Auto Root for 6.0.1 on the T710. Use that one.

You don't need a permissive kernel. That's only for users still running Lollipop.

So, just flash the correct CF Auto Root and you'll be rooted.
[Galaxy Tab S2 General] riane9:
Can you show me the link please? I can't find it. It got me into bootloop. :(

---------- Post added at 08:02 PM ---------- Previous post was at 07:52 PM ----------

I have read somewhere that flashing this rom (UK based) will lose the 5ghz wifi. So I think you will need to wait for the rom that is region specific for your device and then flash it.
[Galaxy Tab S2 General] ianmacd:
Use the one on [URL="https://autoroot.chainfire.eu/]this page[/URL]. Search in the page for T710. There's only one version for this device, for 6.0.1, and with an MD5 of 9ef6846bc30855a059de20c6e4d7c1ed.

This may not fix your boot loop, since I'm not sure what caused it. If you're still looping after installing CF Auto Root, reflash your stock firmware and try again.
[Galaxy Tab S2 General] riane9:
Do I still need to flash twrp?

EDIT: Never mind. I've done it. Thank you so much!!!
[Galaxy Tab S2 General] pavel.bosco:
works fine.

for some reason it shown some message like "failed setting up dirty target" on first run, but after disconnect and reboot, everything started up normally.

thank you very much for detailed instruction and links
[Galaxy Tab S2 General] Grandroidster:
well, i did everything in the OP instruction and MM worked perfectly for me.. only thing i did differently was use CF's 6.0.1 auto root for rooting it instead.. flawless victory i must say.

thanks for everything OP and the comments. :)

BTW i'm using the nook t710 US..Don't know if that helps but happy flashing.
[Galaxy Tab S2 General] riane9:
Does all the T710 have the 5g wifi feature? I don't know if have that before. Where can I check it?
[Galaxy Tab S2 General] nolook:
FYI: you don't lose all of 5ghz just change your router channel to 40 or below to get it back...

edit: this is just for north american models...as per comment below if you have an EU model it should just work without any changes
[Galaxy Tab S2 General] riane9:
Sorry for the noob question, but where can I see that setting? Or should I install a 3rd party app
[Galaxy Tab S2 General] vernmcc:
I had to install the beta 2.74 to get root, but it works now.
[Galaxy Tab S2 General] mattbeau:
I had better luck installing su 2.74(beta)

Im running nekid rom MM, twrp and

Su 2.74

Edit: sorry i didnt go to the last page
[Galaxy Tab S2 General] ianmacd:
Whether you lose any of the 5 Ghz band depends on the region for which your device was manufactured.

For example, if your device is European, you won't lose any of the 5 gHz band when you install this firmware.

Don't assume that every user has a device manufactured for the American market. That leads to confusing and inaccurate blanket statements.

Incidentally, the differences between the US and European frequencies are more subtle than you suggest. If you set your American router to channel 38, for example, your T710 running European firmware almost certainly won't be able to connect.
[Galaxy Tab S2 General] JustMeToo:
Thanks for the help. My bad, though. I had no root. I tried ES File Explorer and it said that the Root Explorer feature can't work on my device. I thought that it was because of the lack of root so I checked with two different root checker and both said I have root. Ergo...ES File Explorer doesn't like root on MM. It did play nice, though, on LL.

Update: Found a solution to the ES File Explorer.

Download 'Root Explorer' or any other rootable File Manager from store (make sure to grant root access and enable r/w) then COPY all the files in /su/bin to /system/xbin. Now ES File Explorer works like a charm.

Got the solution here: https://disqus.com/home/discussion/mjdseo/how_to_enable_root_browsing_in_es_file_explorer/
[Galaxy Tab S2 General] ianmacd:
Alternatively, just creating /system/bin/su as an empty file would be sufficient. If SuperSU sees that file at boot, it copies a copy of the su binary to that location.

OT FYI: Please note that there are growing concerns about the continued use of ES File Explorer.
[Galaxy Tab S2 General] engine95:
Just do a /system root and EVERYTHING is fine. systemless is causing everyone issues. Not just Estrong.

All kinds of needed info in the "maker" thread. For everybody.

Systemless is writing to the kernel, not the rom. And most things look in /system which is ROM.

It's getting old seeing the same new thread with the same questions, when all it takes is a little reading and research first.

And this is what amazes me. Make a backup FIRST should ALWAYS be done before any mod. Then if something's not working right, just restore.

Sorry. End of my rant.

Edit: All this isn't directed at just the 710. But since this forum is pretty small, I read ALL the posts to see if I can figure things out. It can be done in about an hour. Then just a few minutes a day, keeps me up to date. If anyone else does the same, they see what I'm talking about above.
[Galaxy Tab S2 General] lewmur:
Question about 5g wifi

Before I get clobbered, I want to state that I HAVE searched for the answer to this. Both in XDA and Google and either get TMI or not enough. I'm assuming that the problems those in other regions are have with 5g wifi is NOT that 5g itself is disabled in the ROM but rather that different countries allow different channels within the band. So, my first question is, is that assumption correct?

If it is, then my next logical assumption would be that there is a file somewhere that tells the ROM for particular country or region, what channels to scan. If that assumption is correct, then the next question would be, is that file the same in MM as it is in LL, and if so would replacing the current file in MM with the one from the LL file for one's own country/region fix the 5g problem?

If I'm way off with this line of thinking, then I apologize, but, as I said, I tried searching for the answer and couldn't fined it.
[Galaxy Tab S2 General] engine95:
5g works with channels 40 and lower in the US. I have personally looked and tried. I've read that European countries don't allow or need the higher frequencies. Something like that.

As for the higher channels, I'm not sure if it's Rom or kernel. I'm pretty sure it's Rom though as I haven't seen anything in the kernel about it. But I haven't looked either.

It's hard to say what will work on M if using L. As everything I've looked at has changed. Although kernel source is kinda similar. Just more added

I see and hear things that people think we need with M because we did with L. But it's like comparing any version of Windows with another. They just aren't the same.

You may be able to change region in the build.prop but that may not work if that region isn't referenced in the wlan and/ or wifi folders/files. And those are scattered all over.

Sorry. Another long winded answer. But then, we're all pushing and learning a new OS not designed for everyone. Yet.

[Galaxy Tab S2 General] ianmacd:
Systemless certainly isn't causing everyone issues. I probably have 20 root apps on my phone and tablet, and only Secure Settings doesn't work with systemless out of the box. And even that app is easily tricked into working.

The few problems thrown up by systemless root are far outweighed by its advantages. That you keep seeing the same questions and answers about the same issues is the result of two things.

Firstly, systemless is still rather new and knowledge of which few apps present problems and what the standard workarounds are hasn't yet propagated to all corners of the rooting community. This will improve over time.

Secondly, as you say:

There I must concur. The knowledge is often already out there, but far too many people steam into a long-running thread and post their question without even reading post #1, which very often is bang up to date and contains the answer to their question.

This seems to be a big problem on XDA now. Most of the traffic to some of the threads I follow consists of repeat asking and answering of questions already covered in detail earlier in the thread. People just can't be bothered to wade through the text, instead hoping that someone will post a quick answer to their quick question. People are too busy and/or lazy to make the effort. The result is that the thread gets even longer and even more unappealing and laborious to wade through.

You see the same thing when users are asked to post their logs. Immediately, 50% of the posted issues appear to miraculously fix themselves, since the users never come back with the requested logs. Either the problems are temporary, or the users just can't be bothered (or don't know how to capture the logs, but again, that can be learned in a few minutes with a little digging).

Hmm, I came here to slightly disagree, but ended up joining your rant. :laugh:
[Galaxy Tab S2 General] engine95:
And I totally agree. No argument with anyone here.

But the sure-fire way to make EVERYTHING with right now is /sytem root.

Yes, systemless is new as I've said many a time. And yes, it will get better the more we use it. That's probably the way things will go.

My point was, and to help with less clutter, just do /system root for now. Everything will work. Then make a backup, and update things when the dust settles.

I also added an edit to my above posts to explain where I'm coming from.

Sorry if my posts were offensive. I didn't mean them that way.
[Galaxy Tab S2 General] JustMeToo:
Just as a FYI. I didn't do system less on purpose. All I did was follow the instruction for installing MM and then TWRP and then SuperSU. Did't do anything that was not said in the instructions. That it turned out to be system less didn't dawn on me until you mentioned it in your previous post. Of course I didn't read your instruction in the maker thread because my source for the MM was Sam Mobile.

BTW, even in hind sight, I did the right thing. The way I did it every thing worked fine, only ES File Explorer was amiss and that is the creator's fault for not updating to the newest system. And even then, I didn't really need ES File Explorer, the app Root Browser can do every thing and it did it with no complains. :D
[Galaxy Tab S2 General] lewmur:
I'm not all that concerned about waiting for the U.S. version. But this appears to be a recurring problem each time a new version arrives and I was hoping that someone with the knowledge of the actual cause would respond with a suggested cure rather than just making everyone wait time and time again.
[Galaxy Tab S2 General] engine95:
Really? My bad then. Tappin out
[Galaxy Tab S2 General] ianmacd:
A cure for what? The US 5 Ghz frequencies not being identical to European ones?
[Galaxy Tab S2 General] lewmur:
AS I predicted in my OP, there was going to be a smarta$$ response that insinuated I was asking a "dumb question" 'cause I didn't understand the problem. The fact that there are different 5g channels in different countries/regions was stated in the OP. That doesn't mean that one wifi driver can't support them all. It is done by many Linux distros.
[Galaxy Tab S2 General] ianmacd:
FWIW, whilst I'm not above making the occasional smartarse response when I feel one is warranted, my question to you was genuine. I wasn't sure which "recurring problem" you wanted a "cure" for.

You wrote:

It wasn't clear to me what you felt you were being deliberately and repeatedly made to wait for.
[Galaxy Tab S2 General] DigitalMenace:
Go into your router and change it from Automatic channel on the 5g and try channel 48. It's in the lower band so you'll probably get better speeds as most automatic setting use the higher end. Works perfect for mine

---------- Post added at 11:52 PM ---------- Previous post was at 11:50 PM ----------

It's a router setting, not an android seeing.

---------- Post added at 11:59 PM ---------- Previous post was at 11:52 PM ----------

No, I wouldn't try that. Just change your 5g channel on your router to 48. I say 48 as that channel, at least in my area, had no users, and falls into the legal range for the UK.

I also used region changer from the play store and changed my ROM to be seen as a US version, suddenly netflix started working, though still have to download Vudu movies to watch. I know it the ROM version causing this as Vudu is not available outside the US, but I'm assuming if any updates happen, they'll be us rather than UK.

If you're using the adopted storage option, I recommend formatting the SD card via add shell, before installing anything else. Reboot. Then everything that can be installed on the SD will go there instead of the actual internal.
[Galaxy Tab S2 General] lewmur:
It's not my router with which I have a problem.
[Galaxy Tab S2 General] DigitalMenace:
What channel is the router running 5g on? Typically it's in the 100+ range, and that range is not used in the UK.

I to our thought mine wasn't a router issue until I check it and found it in an in compatable range. The WiFi chip in the UK models are not the same as US.

Does any 5g show up at all? The router dictates the frequency it's sending and receiving, so maybe I'm not understanding your issue, so could you clarify a bit more so a solution can be found?

The only other problem would be the tablet, but if it worked before this upgrade, then it's either an OS problem, or a router channel issue, we'll router or access point.

You. Old try swapping the file out with the lollipop version, it just seems Moore work than necessary. Then again, we'd not be having this discussion if Samsung would just give the US the upgrade.... I love this tablet, but hate Samsung's care free attitude on whether we get the latest OS or not.
[Galaxy Tab S2 General] jaydizman:
I set it to 20/40mps and nothing but when I tried channel 48 it WORKED! That was what I needed to make MM my DD. I've been trying for days thank you! If it helps I have cox with a dual band arris modem/router. Still gets 64mps on speed test too
[Galaxy Tab S2 General] DigitalMenace:
Good to Hear! 48 seems to be the least used channels in the US, so I'm glad that worked out for you.

i drained my battery on my tab and booted it up and the finger scanner did not recognise my fingers and so i had planned tkto install mm and remove the fingerprints and ignoring the problem. Now after i installed mm the finger scanner enlorement tells me to lift of the finger from home key again and again.

And the problem started after full drain of battery by putting to download mode (2% was left).any fixes?????

I flashed the 6.0.2 Firmware for my Region, then flashed TWRP, everything working so far, but after installing SuperSU the device still is not rooted.

When I start the SuperSU app i get a message "There is no su binary installed and supersu cannot install it" can't create it and that I have to root manually.

Can someone tell me what to do or what I've done wrong?

[EDIT] Found the hint with CF Autoroot. I'll try this as soon as I can. Would be nice if this could be mentioned in the OP.

[EDIT] Done.

I had to flash the stock image again, did a factory reset, then flashed cf autoroot and it is rooted now.

Then i flashed TWRP.

Hello everybody,

Is there a way to downgrade to 5.1.1? For some reason everything work but QuickConnect no.
