Trouble with new firmware on SM-T800X (Live Demo Unit) - Galaxy Tab S Q&A, Help & Troubleshooting

Hi everyone!
I have a Galaxy tab S SM-T800X (the "Live Demo Unit" edition), and I have tried to flash the stock SM-T800X ROM with a stock SM-T800 5.0.2 ROM (T800XXU1BOJ1_T800PHN1BOG1) using Odin. This did work for me, kinda.. I succeeded in changing the firmware from T-800X to T-800, and the tab stopped playing those anoying demo clips, however the loading screen still says "Live Demo Unit", and I still can't delete the pre-installed demo content apps. I also got this watermark like text in the bottom left corner of the screen. This is all new to me, and I have spent a week experimenting, reading topics, and forums on this subject, but I couldn't figure out how to solve this problem. I hope that someone will be kind enough to explain to me (in a noob friendly way) how to solve this.
Thank you in advance!

Ensure FRP is not active, Install twrp, factory reset, Install stock firmware with odin.

I would like to remove the starting screen ''Live demo unit'' on SM-T800X tablet to the stock one, and after flashing I have got the demo pieces of text in the bottom of the screen.
I tried to re-partition the install with ODIN and used a PIT file but no changes. Anybody can help with this problem please ? Is there any solution to change the demo unit to look as a stock SM-T800 ?
Also if there any solution to change KNOX value to 0 would be great.

I have swapped motherboards from full working SM-T800 to the base SM-T800X and watermark still stays on the screen, it is not very noticable but I want to remove that permanently.
Starting screen has changed to ''Galaxy Tab S" no more live demo unit.
I don't understand that I was thinking that all the flash memory is on the MB, but now I don't know what should I think about it. It looked that screen has his own memory and display the watermark still.

[Q]SM-T520 Rooted for Firewall but no Screen mirroring anymore :(

Hi there Guys
I´m total new on Android.Have my SM-T520 since two Weeks know.My last Boyfriend teached me alot into
the Computer-things.BtW, if you think Im writing stupid ... im from Germany LoL ... My english has
rotten a little bit. So sorry ... have merci please with me.
So ... I was told: Every Computer online needs a Firewall.I searched for an APP for my new Tablet ...
... found one, but it want´s a root? Searched for ROOT and find:
androidpulp.blogspot.de/2014/03/how-to-root-samsung-galaxy-tab-pro-101
I did everything exactly written ... was very nervous " should I? Or better not? Uhhh ... This WARNINGS
My new sweet Tablet! But I did it !! and it WORKS !!! My biggest Computer-thing I ever done. :laugh: :good:
So, I put this CF-Auto-Root-picassowifi-picassowifixx-smt520.tar.md5 File onto my Tablet.The "Root-Test"
was the installing of the AFWall+ Friewall ... It works! Great ! I rooted my Tab! Alone by myself !!
Told everyone from my Adventure the next Days.
But, I brought the Tab for relaxed surfing on my Sofa? (Couch?) and or streaming Movies from Sites to my
Samsung Smart TV.This SCREEN MIRRORING thing.I tested it a little BEFORE my rooting.I worked great.Now
it breaks up with a "Hardware Error" in the end of the connecting process.
So, searched again for that and found out that this Error came from the Root ... from the "Root-Counter",
I think? Searched again ... TRIANGLE AWAY app was found and installed.When I press RESET FLASH COUNTER
the app told me its resseting.But the counter dont go to zero ?? The last message told me
"... make sure you dont running a custom kernel ?? or custom recovery ..." ??
The TRIANGLE AWAY Flash Counter Status show to me:
Cuurent status:
Counter 1
Binary Custom
Device SM-t520
System Offical
When I put my Tab in this Download Mode? It says "ODIN Mode" itself?
ODIN MODE
PRODUCT NAME: SM-T520
CURRENT BINARY: Custom
SYSTEM STATUS: Offical
KNOX WARRENTY VOID: 1
AP SWREV: A1
I searched nearly a week ... landing a lot in this community here ... register on SAMMOBILE ...
thought that this File here is original:
sammobile.com/firmwares/3/?download=32752
Model: SM-T520
Model name: GALAXY TabPRO 10.1 Wi-Fi
Country: Germany
Version: Android 4.4.2
Changelist: 1977750
Build date: Tue, 24 Jun 2014 08:31:35 +0000
Product Code: DBT
PDA: T520XXUANF4
CSC: T520DBTANF1
MODEM: T520XXUANF4
But ... the File CF-Auto-Root-picassowifi ... was 21 MB big the File on SamMobile is 1,2 GB!! big.
I think I not right here.Im totaly confused now.Want to do this thing alone with no help from my Workmates.
It starts so good but now Im out of order.
ROM, Kernel, Firmware, Recovery ... all that I found with Google ?? I think I reached my Limit here.
SO, the Binary is the thing to do? Or ?? Is that a Kernel, ROM, Firmware or Recovery ??? This thing must be
original? Original to be able to reset the Counter to Zero and can do that SCREEN MIORRORING again?
My wish would be:
Keep the Root and the Firewall and also put the Counter to zero to be able to see the picture of my Tab on
my Samsung TV again.
PLEASE ... what kind of File do I need now?What I have to do with that?Is it possible to keep Firewall working
and ScreenMirroring?
Please does someone of you have a LINK that help me? What is a BINARY, please?
I THANK YOU all for reading my looong Story :good::good: Maybe someone knows what I have do do?
Greeting from Germany
Your Nina
too loong ? XD
Hmmmm .... to put it in short ...
Is it possible to have a rooted Tab AND use the
Samsung ScreenMirroring Funktion?
Please, how can I replace the custom BINARY with a stock Binary that
runs with my rooted system?
A Link or a good Searchword for Mrs.Google would help me so much.
Have a nice Evening

based on my experience with my other Smasung phones, yes it should work, as long as you are still running Stock firmware.

Thank you for your Answering
So,it may possible to keep root and firewall AND
use the screen-mirroring?
My problem is, what file do i need for that?
LoL ... I dont know the exactly name of and sadly l cant find out what kind of File?
A kernel, a firmware, a recovery or a rom?
I need a binary right? Or not?
What is a binary ... a rom kernel firmware or recovery?
I searched for hours now but cound find a Answer. :crying:
So, you mean I need a Firmware?
Please, do you have a Link? For the file and a how to do,maybe?
The Data is posted in my looong Story in my first post.
It starts so well and ended in a mission impossible for me now.
I thought someone here did it before with a sm-t520 10.0 pro tab.
Maybe ??
Have a Nice Day

1. Unfortunately, the Knox counter cannot be reset at this time.
2. If you have not installed any recovery, or other ROMs, Kernel, then you are running STOCK firmware.
3. Have you tried to reset your device and see if mirroring works? This is what I did with my S4 before and it worked, but I don't really know with the Tab pro because i have not rooted it as I want to use Knox.
4. If after you have reset your device, and screen mirroring does not work, try to download a STOCk firmware from www.samfirmware.com or www.samsung-updates.com and flash it to your device using ODIN - this is run on your COMPUTER with your Tab pro connected via USB cable. This will UNROOT your device. Then try to use screen mirroring again and see if it works. If screen mirroring works, then it means you can't root your devic if you want to use screen mirroring.
5. There are free firewalls on google play, but I have not used any of them so i cannot comment which one is the best.
I suggest before you make changes to your Tab Pro from now on, go and read more about rooting, flashing ROMs, flashing RECOVERY... it is best NOT to RUSH what you want to do as an ERROR on your part might cause more problems.
a lot of THANKS

Thank you !
I will test that RESET with TriangleAway and then test ScreenMirroring this afternoon. Nice Idea :good: Hope it works.
I only put CF-Auto-Root-picassowifi-picassowifixx-smt520.tar.md5 one Time to my Tablet and it was the only
thing I put on with Odin.
My Problem with this Firmware-Download-Sites samfirmwar is, that my File:
Model: SM-T520 PDA: T520XXUANF4
(I cant put a Link in my Postings)
is too big!! It´s 1,2GB big and the File i did (CF-Auto-Root-picassowifi-picassowifixx-smt520.tar.md5) is only
21MB.Could that be right?? My only nonStock-File on my Tab is the BINARY, as TriangleAway and
the Download Page said.
I read a lot last two weeks ... i looked for me like theres no solution at that Time.
Couldn't find a Posting like "rooted SM-T520 WITH SreenMirroring"
Maybe my Tab its to new? Read from Lib-Files that must be changed but not for the SM-T520.
Thanks for your help !! I will test your Point 3 a little later. Hope ...
Have a nice Day

Chainfire doesn't flash a new system. It replaces your recovery, then adds some files to root your existing /system, and then replaces your recovery with a stock version (which may be different than the stock version your started with, but is a Samsung recovery at least).
That's why it is so much smaller.
I'm guessing here because I have not entirely figured out what Samsung has done with their Digital Rights Management stack. But, screen mirroring may have issues because it may require DRM keys (probably hdcp keys) and by tripping Knox it may be going from DRM level 1 for which it has keys to DRM level 3 for which the device may not have usable keys.
I agree with the recommendation to try using Odin to undo everything except tripping the Knox counter. That's your best shot.

Sounds like you are much into it.
But I understand nearly half what you write about DRM and so. But THANKS for your Time.
Because of you I know now why it is so big.
I started the 1.2GB Download at the End of my last Posting ... still 6 hours left :silly: to finish. 30kb sec
So, when Download is ready and I put it with Odin on my Pad ... is the complete System new then?
The Binary is then Stock or offical and I can put the Counter with TriangleAway to zero?
Read this morning that this wont go because its now Hardware based. a fuse or so.
So I do the big File on my Pad to get the complete stock System back and the ScreenMirroring option running?
Sorry for my stupid ... I read really a lot ... but its also a lot of "ways" and "to do" written out there.
The Test resetting with TriangleAway and test the ScreenMirroring didn't worked here.
The Pad is scanning long Time but couldn't find the TV.Yes ... it´s in the allowed List in Menu.
Did the same as before the root.But the Idea was good.
In all the "how to root" Sites in the Internet should written that some functions wound´t work after root as Warning ... ... maybe ... special for rooters like me
I read we can unroot the Pad with SU.Looked in the Menu ... there´s really a Point called unroot.
But that wound´t bring ScreenMirroring back or? Sounds to easy, or?
So, see you next Time
Bye for now your Nina

totally agree
i think our german girl must have stuffed something up during flashing
flash back it to the original stock rom using odin and keep it as unrooted. my wife has an unrooted p600 and to honest, i cant see any point to root her device at all. based on what she or probably this girl wants to use it for.

¿SDS? ¿Brick? ¿Hope for me?

First of all, sorry for my poor English. I hope any of you could help me with this.
I have a GT-N7100. The terminal had a few days causing problems slowdowns style and so on. Suddenly I get the message "System uid inconsistent" appears and, after the corresponding scares, it seems that the solution passes through a "fix permissions". I do it and it seems quite right when, after a normal restart gone me of my data. To understand, I still get the app whatsapp as user but I have to reconfigure, like the rest of the apps.
Thinking that the problem is the inconsistency that I take to be able to reset and flash the latest SamMobile, the N7100XXUFOC2. Well, everything smoothly and mobile up and running until I turn it off and turn back to me and does not pass the logo of "Samsung Galaxy Note II".
Well, I could do nothing at all to revive. All gave me error, re-flash the rom itself, repartition, bootloader, try a recovery ....
I found a "rom factory" in an Arab forum, the N7100XXUFND4, with its pit, the bootloader, AP, and csc all cp "low end user" and either.
I also tried the xda thread of making your own rescue tar and nothing.
What I have seen on youtube is a colleague teaching the same screen attached the pictures and saying it is a sudden death affected. The fact is that I have gone to hell partitions.
Note had only 3 years. I posted this in a Spanish fórum but i had no answer. ¿What do you think?
Thanks!!!

I tried odin with a Factory rom and nothing. Kies allow an emergency firmware update but could not start process (think due partition).
Thanks for the reply. I will think a lot next time for Samsung.

Need help about T800 Tab Retail Mode (PIT file needed)

Hi guys,
Yesterday i bought a new Galaxy Tab S Live Demo Unit, i wanted to remove all retail mode things and factory reset the tab, after reseting the tab i flashed latest Lollipop build with CF Auto-Root and TWRP but i want to totally remove all the text written under the screen in the left side, anyone know how to remove them ?
I tried reseting, flashing a custom rom (CM-12.1) but no luck.
I think samsung have a hidden partition that block people removing the text...
Im waiting your help guys.
Oh and a last thing, can anyone post the PIT file from original T800 stock rom please ? I want to try a repartition to see if it fix my problem
Thanks in advance.
Firstly you've created a voting thread. This wont get many views as it not displayed in the app.
Second you shouldn't need the pit file and they are posted on this forum.
Third just install twrp, factory reset then install the stock rom.
Sorry for the wrong things.
Okey for the pit.
I tried but no luck removing the text, i will open a new thread 😊 Thanks anyway
Well it worked for everyone else. What text is it you see?

Smt900 12.2 store demo mode

A friend on mines recently purchased a second hand smt900 tab pro.
it's got a live store demo firmware on it. Any ideas how I can get ride of this? Will it be a simple root and flash custom roms or will it be a little more tricky?
Obviously i don't wanna try and be the helpful friend and try to stick in the software and root that I know I can do if this software is gonna cause problems. It works fine now but won't update.
Cheers
Ian
I'd try Odin with a stock ROM
Apparently the demo modes locked on and it keeps reverting back no matter what. That's just what I am reading. I was wondering of anybody has flashed before I start messing about
Anybody? Help please Hello.
Pretty helpful information cheers people [emoji23] [emoji23] [emoji23]
Pretty sure this is what I used on mine. It's been a while but I used it recently on a tab 4 10"
-Find and open Samsung Retail Mode app.
-Tap on Configuration Settings.
-A new window will appear. Enter the password 5444 and click OK.
-The Admin Menu will be unlocked.
-Now turn off “disable the factory data reset”.
-Enter the password M729Q16K8546 and then click OK.
-You will be prompted to Factory Reset the phone/tablet.

T807A Recovery Help

Hi there,
I recently purchased a Tab S 10.5 off of eBay from a seller that said they'd messed up a custom ROM installation and with a cursory amount of research I saw that it was possible to return it to factory and had no issue putting in the leg work to get it done. However, I'm finding that my own knowledge of rooting and custom ROMs isn't sufficient for this situation now that I've gotten stuck into it. The tablet shows the Tab S logo and then immediately displays a message that says the software isn't official ATT and to return to a store for assistance. When I try to boot into the recovery menu I'm met with a screen that has a large android and says, 'Downloading...' and I can't get any further there either.
I've tried flashing recovery files with Odin but they have all failed and have also tried the Turkish image and it just sits at, '<ID:0/004> SetupConnection.." and doesn't initialize.
I've also gotten a, 'NAND StartWrite FAIL!!' notice as well.
I got the thing for a steal and would love it if it were possible to return it to factory and was just curious what kind of options I had at this point. Are there any program alternatives to Odin or different recovery files to use mayhaps?
I'm wondering if buying a new logic board would fix the issue at this point but, wanted to double check that it wouldn't cause any differing problems than the issue I'm experiencing now.
Edit: Odin finally got passed the, 'SetupConnection' line for the Turkish image and displayed this next: '<ID:0/004> Can't open the serial(COM) port.' - This is the first time it's displayed this message and I'm not sure what to do about this either.
T807a firmware isn't available afaik.

Are there any other versions of the firmware that would work instead?
Regarding the rest of my questions, I'm really just interested at this point if replacing the logic board would fix the issue. If anyone has tried that at least.
