WiFi problems can be related to wrong firmware.

Which firmware have you flashed?

Also is the issue connecting or turning on?
[Galaxy Tab S Android Development] adroit_y2k:
Hello ashyx, the issue is with turning on itself. As mentioned earlier as well that everything was working fine for over two months and one fine day the wifi stopped working..when this happened approx two weeks ago, wifi would connect intermittently for a few minutes and then it stopped completely. The issue was with turning on the wifi itself. The wifi switch will slide to on position but would remain greyed out. It would not turn green. So effectively i am unable to switch on the wifi itself in the tablet.

The reason for description is that i did not change any firmware or did not do any modification when the wifi trouble started..do you think it could be a hardware issue?

I am a bit saddened because i simply love this tablet and would like it be alive again.. I can give you more details if you wish..quite desperate now to get it working!!

Attached is the screenshot of the firmware details at the moment.

Many thanks
[Galaxy Tab S Android Development] adroit_y2k:
I was even risking getting to try flashing the version 6 from your other post although you mentioned it was for only t700 and not t705, thinking i might get the wifi to work..
[Galaxy Tab S Android Development] adroit_y2k:
Any other suggestions for me ashyx? Still struggling to get the wifi and bluetooth switched on

[Galaxy Tab S Android Development] Mr. Whippy:
I've been looking into rooting my Tab S (T800) and finally got to this thread. If I'm reading this right, I only need to flash the correct autoroot tar and it should take care of everything? I'm backed up, and have a stock image in back up just in case, but I don't need any other files besides the autoroot for the T800? Seems almost too good to be true... :)

LRX22G.T800XXU1BOL1 Security Update for Samsung Tab S T800

I recently received a T800 and came here to learn how to root it. I have rooted a few different units before but I'm not really fully comfortable rooting yet. So please excuse me for asking some beginner questions ... I know just enough to really get myself in trouble with rooting. I'm not sure I'm even posting this in the correct thread.

Here are my questions: The T800 WIFI I have has a build number of LRX22G.T800XXU1BOL1 released on Dec 7 2015. Which CF AutoRoot do I use? Which TWRP should I use? (And BTW, I'm a Mac OS user and use Parallels emulation software on Windows 7 to root all my devices, but this shouldn't be a factor in this root.) Any and all advice is greatly appreciated. Thanks.

Hi..I want to root this t800 but its a retail demo version and I have flashed lolipop but cannot delete the old retail files as the drive says its protected and it seems to have an almost full drive about 7.60 of an 8gb drive and I have not installed much...so I am stuck with next move before this root I think clear space but not sure how any ideas please..
[Galaxy Tab S Android Development] meduza:
...well, if you install TWRP you would be able to erase your whole internal SD...

[Galaxy Tab S Android Development] B3NJY:
Ahhh thank you for that ...just rooted it with this auto root big thanks to you M :) donated 10 bucks and a big thank you ...so now maybe I have a little more acess ,,if I install a rom will that do it or is is something to do with partitions ?
[Galaxy Tab S Android Development] meduza:
Glad to hear m8 :)

There is nothing more to do then to follow instruction from the OP of your ROM thread.

m.
[Galaxy Tab S Android Development] blu2:
Thank you M!

I'll give it a try. I was thinking that the new update, LRX22G.T800XXU1BOL1, might mess things up. I'll let you know how the rooting goes.

Thanks again!

Update: I followed the instructions that were linked to the link you listed above. The link was for the Tab S 8.4 LP but I just substituted everything for the Tab S 10.5. When I booted into the recovery mode using Odin3 v 3.07, I didn't get the "WARNING" Page, instead, I got the attached picture. Where should I go now to finish the Odin flashing of the CF autoroot T800? Thanks again for any direction.
[Galaxy Tab S Android Development] meduza:
.....I don't understand what you're doing... ?!? The link was for T700, t705, t800, t805. Please read the OP of that thread carefully! Odin works with your PC.! We shouldn't go OT in this thread here, so if you have problem, you should ask over there.

m.
[Galaxy Tab S Android Development] ashyx:
What's happened there is you've replaced twrp and root with stock because you have flashed the stock firmware or you didn't boot to recovery immediately after flashing.

The procedure to remove demo mode:

Install twrp or run the same cf_autoroot again.

However this time uncheck auto reboot in Odin, immediately after flashing boot into twrp and factory reset.

Manual reboot is POWER + HOME +VOL DOWN then as soon as the screen goes blank immediately change to VOL UP whilst still holding the other buttons.

Next reboot to download mode and install the stock firmware(if you have already done that then you can probably skip it)

Reboot and enjoy your demo free tablet.

Note: just be aware any time you flash the stock firmware you will need to reroot afterwards.

[Galaxy Tab S Android Development] blu2:
I think there might be some confusion with a different poster earlier ... I don't have a problem with the "demo" mode. That was another person. My T800 is a new unit. I followed this link from meduza2:

This here should do it:http://xdaforums.com/gala...-t800-t3079488

I downloaded the T800 CF Autoroot and went to this link ...

(Guide how to flash, credit to Usama m. http://techbeasts.com/2015/05/01/roo...-lollipop-502/)

... for the step by step instructions, even though it was for the T700, I substituted for my T800. I haven't flashed anything yet. I just went to step 1 of that link ...

"How To Root & Install TWRP Recovery On Galaxy Tab S 8.4 Running Android Lollipop

1. Put your Galaxy Tab S 8.4 in download mode. To do so, turn it off completely. Now turn it on by pressing and holding Volume Down + Home + Power Key. Once it boots up and shows warning, press Volume Up to continue."

When I didn't see the "Warning" screen, that's where I stopped and came back here with an update. Am I following the correct directions from the previous link or should I just follow your current instructions for removing the Demo mode? Or should I be doing some other procedure?

So sorry if I'm being long winded but I wanted the details to be known. Also, I'm leaving for China for a several days for work tomorrow and won't have access to this site till I return. But I'll address this first thread as soon as I return. Thank you again for all the help!
[Galaxy Tab S Android Development] ashyx:
I see I got you mixed up with another poster.

The link you posted is the same thread you're posting in.

You didn't boot to Download mode you booted to recovery mode.

Download mode is POWER + HOME +VOL DOWN not POWER + HOME +VOL UP.

Flash the appropriate file for your device at the beginning of this thread with odin.
[Galaxy Tab S Android Development] blu2:
ashyx, ... back from China now.

Thanks! I followed your instructions. I'm rooted now. Discovered the reason I booted into recovery ... I have rooted a T700, and the "up" volume button is closest to the power button, on the T800, it is exactly opposite. So, I booted into the recovery instead by mistake & didn't realize there was a download and recovery mode available from the same buttons ... I'm always learning. I greatly appreciate the patience & instructions from those of us with less knowledge, Thank You! (I also clicked the thanks button.)

[Galaxy Tab S Android Development] BlueBlazer23:
Does it work for T805 woth latest 5.0.2 firmware (BOL) or should I downgrade first?

[Galaxy Tab S Android Development] Bdozier:
Rooted my SM-T800 last night with this method. I am on Build BOL1. It was a FAST process! I was able to do it while my wife got ready for us to go out... so I had the time! I was even able to Nandroid almost 10gb!

ashyx put together a great tool of Chainfire and TWRP products.

Thanks!

---------- Post added at 08:47 AM ---------- Previous post was at 08:29 AM ----------

If you are still wondering...

Follow the guide that is linked in the OP. I rooted with this method last night. I will say that the guide doesn't plainly say to, but I disconnected my usb cable after Odin was finished. At the same time that I disconnected, it auto rebooted into recovery and finished the install on it's own. In short, my SM-T800 was only connected during the Odin process.

Even though the guide doesn't say "Now, disconnect usb", I urge you to read, read, read all of the posts to a method you are going to follow as questions like these are answered in the forum. If a post suggests a link to another method or whatever, follow it and read that post and replies (that's how I found this method). Education is never a bad thing before trying something new. I am not suggesting you didn't, just reminding others that are reading this despite it being an obvious statement.
[Galaxy Tab S Android Development] néonaloj:
Thanks for this tool, [MENTION=4899305]ashyx[/MENTION] ! I could root and install twrp whithin a few minutes on my new tab s. Working great and easy. Thanks again.

[Galaxy Tab S Android Development] megagrumpy:
Total newbie to rooting

I have an SM-T800 with Android version 5.0.2 and have looked on Google for instructions on how to root. There seems to be a lot of different people who post stuff and even I can see that there are contradictions between one person and another. Also links that are provided point to scamming sites which gets me a little worried. As far as I can make out Odin is the key to download twrp but on some sites you uncheck the Auto reboot and some sites you do not. Also some sites say to download SU to the device and others do not. Is there a definitive step by step guide that is up to date? It probably exists on this forum but I could do with a little help in finding it and I apologize if this is seen as a naive and time wasting request.
[Galaxy Tab S Android Development] JaeFern:
Download Odin.

Download the file on the OP (Original post) and follow the guide that is also on the OP. You'll be done in a few minutes, and will also be surprised at how quick and easy it was.
[Galaxy Tab S Android Development] néonaloj:
+1! I did use the instructions in the OP and in few minutes it was done. Good flash!
[Galaxy Tab S Android Development] megagrumpy:
Another question

One small additional question. In the instructions in the OP it says "If Auto-reboot is unticked in your Odin, tick it". Then in the screenshot immediately after it states "Untick all other options except F.Reset Time". I have looked at many other posts and it appears that it can be done either way but just want to check before I take the plunge!
[Galaxy Tab S Android Development] ashyx:
If you don't untick it then twrp may get replaced with stock recovery.
[Galaxy Tab S Android Development] megagrumpy:
Still stuck

I have followed all the instructions to root my SM-T800. I ran odin v3.10.6 and used it to Flash twrp_3.0.2-1_sm-t800.tar

I then held the power, Vdown and reset buttons until I got a blank screen and then held power, Vup and reset until device booted.

Device goes into the twrp screen and I have lots of options - presumably the right option is install. If I hit Install it wants me to find the twrp file but I am not sure where it is.

I realize that I have probably made a complete Newbie mistake but I have spent a long time reading through all the posts and cannot find the answer.
[Galaxy Tab S Android Development] meduza:
But what do you want to install? Put the file you wish to install in a folder on internal or external SD so you can easy find it.

m.
[Galaxy Tab S Android Development] megagrumpy:
I want to install SuperSU but the instructions say that this is now bundled with twrp so I would expect it to be installed as part of the flashing and installation of twrp. Maybe it is already there but I am not sure if I should just reset now or should I do something else? Worried that if I reset I will mess it up.
[Galaxy Tab S Android Development] meduza:
If you`re in the ROM, you can check if you have root or not. If yes, everything is fine, if not just flash the superSU zip like described. That's all.

m.
[Galaxy Tab S Android Development] ashyx:
You just need to reboot. The option to root will then be offered.
[Galaxy Tab S Android Development] megagrumpy:
If I select Reboot I get 4 options - System, Recovery, Download and Power Off. Sorry to be so dense but which one is it?
[Galaxy Tab S Android Development] ashyx:
Any. Just reboot it doesn't matter. System will be fine.
[Galaxy Tab S Android Development] megagrumpy:
Do not know how it worked but Supersu is there now! Validator was saying that there was an exit code problem but now I get all ticks. Thanks for your help and now I guess I need to find out how to use it to get rid of some of the Samsung apps to claim back some memory.
[Galaxy Tab S Android Development] ashyx:
Word of advice before modifying anything.

Boot to Twrp and tick all the partition boxes to make a full backup.

You can then do what you want knowing if anything goes wrong, it's just a simple matter of restoring your backup.
[Galaxy Tab S Android Development] kywildcat:
So this is probably a stupid question, but will this reset my device to factory? Or will everything be left intact?

Don't worry m8, everything will stay like it is

[Galaxy Tab S Android Development] shepscrook:

I can get into recovery, no problem. Any suggestions? It's a stock unit that I've factory reset.

You're probably pressing VOL UP instead of VOL DOWN.

Supersu 2.6.8 (Marshmallow package)

Help!

I have a few questions.

1. Does this have any bugs?

2. Is there a chance I can brick my device?

3. A site told me you need unlocked bootloader to flash twrp, is our bootloader unlocked?

I am on OTA Marshmallow, have usb debugging enabled, have trust untrusted sources checked and have exynos processor, is this ok?

I have the Samsung Galaxy Tab S 8.4 T-700.

Edit: Should I download twrp-3.0.2-0-klimtwifi.img.tar or twrp-3.0.2-0-klimtwifi.img?

Which SuperSU should I flash? this or this

Also should I use odin v3.10, v3.10.5 or v3.10.6?

- Is it ok im on marshmallow?
[Galaxy Tab S Android Development] ashyx:
This is no good for Marshmallow. See my twrp thread. Instructions and guides are in there.
[Galaxy Tab S Android Development] ZimriTech:
I know, I was asking about the method people were posting about. (Flashing twrp through odin and then flashing supersu through twrp)

I figured everything out myself and was able to root my device. Sadly I made a mistake so now my knox is tripped TWICE but that is not really any different then once haha.

I'm sorry for being such a newbie, but if I follow this root guide which looks great, will I be installing the stock android launcher as part of the flashing process or will I still have touch wiz?

My primary purpose for wanting to root is to Greenify and hibernate system apps that would otherwise just reboot themselves repeatedly.

But I read on internet that CF-Auto-Root (with SuperSu) give the root but doesn't have the recovery (useful if I had some problem).

So I'm asking for a TWRP for my T805 withg recovery inside.

You don't need CF auto root. Install TWRP via odin and flash then supersu via TWRP (https://xdaforums.com/galaxy-tab-s/development/twrp-2-8-6-1-unofficial-sm-t800-805-807-t3074633) and that's it, you're rooted :)
