[Q] CustomROM on Pro 10.1 Live Demo Unit SM-T520x - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

Good evening peeps,
My brother has been kindly given an ex demo unit of a Pro 10.1 (SM-T520x) for his son to use.
Does anyone have experience in bringing this back to a fully functioning unit?
I have tried to research as much as possible to avoid asking a question that has been asked many times before.
I can see quite a few threads for different models, each with their own set of challenges (missing hardware, partition size differences,
boot loops etc).
Do these units come with the retail mode app that can be unlocked using the passwords available online?
Am I able to flash a CustomROM to the device?.
Any tips are greatly appreciated.
Tom

Good morning all,
I just thought id pop back here and answer my own question (in case someone else searches looking for the answer).
You can indeed treat the SM-T520x exactly the same as a retail SM-T520
I took the plunge and went for it....
1) Rooted the tablet using 'CF-Auto-Root-picassowifi-picassowifixx-smt520' (via odin).
2) Installed Flashify from the app store.
3) Backed up recovery and kernel (from within flashify).
4) Installed TWRP from within flashify (Followed other advice and installed a 2.7.x.x version).
5) Made a full backup within TWRP.
6) Completed a FULL ADVANCED WIPE within TWRP (everything except external SD Card).
It was then ready for a customROM, I chose 'SMT520_GraveD_V3.0' and flashed it from within TWRP...
My nephen has been using it daily for over a week now and its brilliant. Only remnant left is the initial samsung splash screen still
says 'live demo unit'... but thats no issue at all.... he is well happy.
I hope that might help someone sometime

I have just bought an tab pro 8.4 ex demo unit and I was wondering the same as you did, so thanks for sharing the above info! It will help me a lot.
Did you change the splash screen? I'll probably change that when my tab arrives.
Thanks again, Andy

[Q] Made a n00b mistake on my 8.4 - How do I get back to Stock?

Hi all,
I made a dumb move and installed the CM11 port for my T320 without backing up my Samsung stock firmware. (I'd post over in the appropriate thread in the development section, but I haven't posted here frequently enough to be allowed over there). I want to go back to the Samsung UI for now because I am having some troubles with CM11 ... my tablet thinks it's a phone, so I'm not getting the tablet features and app versions. Plus something is off with my screen so that some apps (Flipboard, at least) runs everything off the right side and bottom of the screen. Anyway, does anyone have an idea of how to get me back to my Samsung UI? I can't get Kies to talk to my tablet (another thing that cropped up with this CM build) so I can't get that to reflash it for me.
I have downloaded an Odin-flashable Samsung stock firmware from Australia (I'm in the US) so I'm guessing that will work, but I'd rather find an easier option before I give my tablet a globetrotting split identity disorder or something.
Please understand, I've rooted, reflashed, and even unbricked devices before, so I'm not new to this, just made a dumb mistake.
I believe that is the only way to go. The good news is you can install twrp recovery now so it shouldnt be an issue again. Bad news is there isnt a flashable stock firmware that I know of yet. Im kinda hoping for cleanrom as he did a hell of a job on the note 3 and knows the system better than most.

I've used Samsung Kies from my PC several time to go back to stock.
When using Kies you may have to switch your connection from MTP to the other option and of course check debug.
I went back and forth from CM11 several time plus I did what you did also except I used the New Zealand version
Here's what I did to restore stock from Kies.
Plug in the tablet, open Kies, and click Tools then Firmware upgrade and initialization. Type in SM-T320, hit okay, then add your serial number.
Basically just follow the steps it asks you and make sure your tablet is in download mode. It will download the stock firmware image and flash it to the device.
My instructions might now be 100% accurate, but that's basically the process I took to restore it to factory.

for anyone looking for twrp for t520 10.1 wifi only

It is auto loaded when you load flashify. Then u can select wether u want twrp or cw recovery.
Hope this helps someone as twrp. Wifi t520 is not available on twrp site.
+1 confirmed it worked on mine (t520).
Can also be retrieved here if you want to flash via Odin.
http://goo.im/devs/OpenRecovery/picassowifi
I fond myself in a situation where my tablet wouldn't boot and I needed to install a custom recovery, so I had to flash via Odin.
I was just going to post a thread about this. Flashify app is the easiest way I have ever used to install custom recovery!
More details?
All,
I rooted my 10.1 yesterday, since ROMS are starting to come out. I used TWRP and CWM on a Toshiba Thrive prior to own the tab pro.
Anyways...I rooted last night with Odin, but still only have the stock recovery.
Please tell me how to get TWRP installed, without messing up the tablet (it is an expensive device, just want to make sure I don't brick it!)
Just flash the zip from the stock recovery?
Unroot and re-root using flashify or Odin?
I can't wait to get rid of all the Samsung crap!!! (but want to backup first)
Thanks a lot,
Damien
Re twrp for t520 and roms
Wish there was some way to help young 14 year old ik4ver [written first custom rom for our device]...some deadbeat loser keeps sabotaging his account now hijacked to extort a rom for the 12.2!!! I have never seen anything like this...hopefully karma works her magic on this scumbag!
I know right...I fortunately got his v3 rom yesterday before his posts got hacked again.
Tried to flash his rom today and almost bricked the tab, twrp couldn't mount ./system. Got stuck on the Samsung logo after this. Fortunately after 3 tries my twrp backup finally restored properly.
Does anyone know the exact steps to follow in twrp before flashing his rom?
Before not being able to mount system, it was saying can't mount cache, which seems to have resolved itself. Weird...

rom thread back up
Can't help yet ..I haven't had balls to flash rom yet lol. Looks like his rom thread is back up and running for now.

Yep...I tried again...
So, in order, I...
- Rooted using Odin
- Install TWRP using Flashify (thanks to K8108 for the earlier post)
- Went to recovery
- Went to "Mount" and made sure all was checked
- Went to "Wipe", "Advanced"
- Checked everything except internal and external storage
- Install ik4evr's ROM
- Rebooted...
Tablet booted no problem (it stays on "SAMSUNG" for a little bit, which worried me...)
All Samsung apps are gone!!!
that's awesome thanks for the procedure details!
Actually it was young ik4evr that let me know bout twrp being auto loaded in flashify .. that's why I started thread as it's kinda confusing as twrp site doesn't list t520 wifi only.
Good work!

This all forum is freaking confsuing, as it is about 6 (8?) different devices, where some are kinda similar, and others completely different (thinking especially of Exynos vs Qualcomm).
Plus there is no real guide, and takes hours trying to figure out if this thread/recovery/rom applies to our device or not.
Plus 8.4 became modrian, and 10.1 picasso.
Yay, confusing is the right word!!!
well I've loaded Treo with flashify and done full stock rooted rom
Backup. Now have to grow a pair and flash ver3 of ik4evrs rom! So you have zero issues and everything working?
I was going to wait at least till his thread gets sorted out...hmmm...i voided warranty anyway at this point lol

Zero issue wouldn't the word lol! I did have a bit of a cold sweat yeterday...
I'd say as long as you have the stock rom backup go for it!
I actually started a thread separated from here. I wonder if "wipe internal storage" ok or not...what I can see is that bunch of folders remained from apps installed before flashing the rom.
As far as the steps listed above, I just did it this morning and all went well. As far as deep testing to see if everything is still working, I can't answer yet (at work, no time to play with it).
Let me know if you have any issue...
Ball grown yet?
Alright...so:
- Went to recovery
- Went to "Mount" and made sure all was checked
- Went to "Wipe", "Advanced"
- Checked everything except external storage
- Install ik4evr's ROM
- Rebooted...
Just reflashed the rom, this time wiping the internal storage as well.
After apps update, 472mb used, 11Gb free (was 6gb used before wiping the internal storage).
So far, the only issue is something I read on a post somewhere, but contacts aren't syncing.
I am sure a V4 will be here soon!!
Everything else seems to be working.

I did the same. All worked.
Unfortunately I cannot restore apps succesfully from Titanium backup. The restore seems to be ok, but I only get FC's. The apps will not start. I cannot find the cause of the errors.
Something in directions of maps destination changed? Knox?
I do not understand it.
I had a hard time with TB also. Had to get most of my apps back from the play store. Lost some data. Oh well. My contacts are syncing from Google, tho.

I always reinstall from the play store... I like it clean and fresh, and I don't have that many apps to restore.
Now...How did you get your contacts? I just installed google+, and my circles finally synced in the contact app. As far as all other contacts (gmail), can't sync them...
Sent from my SM-T520 using Tapatalk
I don't know why my contacts are syncing. The only difference I can see is that in our flashing the rom, I didn't do the advanced wiping. I just did factory reset and cache wipe. I left my system unwiped. I'm not real savvy on this stuff - I have just been a good instruction follower for the past few years and have spent lots of hours reading here on XDA. I am heavily addicted to my tablets and use them for several hours a day so I have over 100 apps. It's a real pain for me to have to go thru the play store for a restore

New to flashing/upgrading

Hi folks,
I'm after some information. My Nexus 4 is about kaput now with the battery lasting about 4 hours or so with a full charge so I am looking to move over to my S4 mini for a while before buying an upgrade.
However i don't fancy rolling back to 4.4.2 from 5.1.1 as have got accustomed to it now. so there for I am looking to upgrade/flash it or whatever.
I am quite the novice and have not done this on any phone before so I am looking for a bit of help,
I have looked over xda and read some bits but think someone just telling me would be better, i'm not a tech dunce but I am not 100% confident in this at the moment as there seems to be more than one way of doing this.
What do i need to do first and foremost to make the process go as planned?
I take it I need to "root" the phone first (what does this do ? give me access to the firmware level? is that it?) using a "recovery tool" as they are called (is that right?)
Then after I have done that I can install a fresh ROM onto the phone and basic app's etc.
I have seen these guides:
http://forum.xda-developers.com/showthread.php?t=2364980
and
http://forum.xda-developers.com/gal...i9190-i9195-cyanogenmod-13-0-s4-mini-t3276141
Is it just a matter of following them or are there other things I need to do first, in between or after?
I am not bothered about anything being saved on the s4 mini it can be wiped clean and start a fresh, I don't need any of my data on it backed up
A quick bullet guide or acknowledgement of the two threads above or pointing me towards some better ones would be great and any pointers or descriptions of the acronyms or places in menu's which may have had their names changed or have been moved.
Many thanks Everyone,
Dahools
Hi!, you dont need to worry about anything, the only thing that you need is follow these guides, but make sure if you have the correct variant.
First Install Kies and connect your phone to it( For correct phone drivers). And after phone connect wells, Close kies from task manager.
You Need Odin to install a recovery software in your phone(TWRP, Clock Recovery, Philip). I only used twrp now.
Here is link below with instruction. Download recovery for your variant(i9190,i9192 or i9195 base on your model).
http://forum.xda-developers.com/showthread.php?t=2678420
Suppose if you install TWRP. Boot into recovery, And click Wipe, Do a factory reset , Clear Devil cache, Then go back and install your Firmware(cm12.1 or cm13 for your intended model). And flash Gapps as well. Then reboot. And you are done.
I have tried TWRP for both i9190 and i9192 model. and installed custom roms. Work fine.
Good Luck.
thanks fellas
I went for it with the original links and it worked. (eventually) A bit of user error on my part missing recovery mode on reboot first time and thinking it was done when it wasn't. Only putting the first bit in (root kit v2) then not realising how to flash the next parts. A bit of persistence paid off.
I have a I9195 model and rooting with that clockwork worked then loading the CM13 and then the Gapps. All one after the other in one go finally worked for me! so so far so good, just getting used to Android 6 now I think everything is working though, not put my sim in yet. will do that tomorrow.
If anyone was to follow what I did the big tip I would say is copy everything onto the SD card before you start anything, not as I did at first just putting the first bit on then thinking I can copy the next bit on later . . .

No OS on galaxy n4 sprint. No back up or restore point

No OS installed. I have twrp installed. So literally when i turn it on it goes directly into recovery menu. Apparently I have no back up or restore point. This is a Sprint galaxy note 4. Does anyone have any suggestions. I have been looking for a factory reset firmware somewhere online cant find one. Funny thing is my wife has the same exact phone. I thought making a back up and restore point for her phone would work on mine, but it didnt lol. Please I would be very grateful for help.
Hello, you could get the official software and use odin to get it back all the way to stock, or you can also just flash a custom rom since you already have twrp. To install a custom rom, all you need to do is download the rom and place it on a micro sd card, boot into twrp, and flash the rom from the micro sd.
Thank you for your reply how ever my trouble is finding an OS that works for my note 4 sprint device. I have downloaded dozens and dozens of different roms and so called " factory firmware" but seem to have no lucks. i have the recovery software installed twrp. when i go into there and try to load rom i still get error that says no os installed..
Thanks for the input i will close this thread now. my problem was not being patient at the bootload screen. I automatically assumed that something was wrong because it was stuck at the sprint spark yellow screen how ever little did i know a little bit of patients would have saved me numerous amounts of hours of research. Lost sleep, called off of work, and canceled weekend plans due to a little lack of patience. Well you live and you learn i really appreciate you taking time out to reply.

First post. Hoping to fix my Tab S

Hi all
I have been pointed towards xda following a conversation in another forum regarding my failing Tab S.
Before I registered today, I took a look around the forum and am left feeling a bit like a duck out of water.
I dont really understand much of the jargon being used, and so im not sure if I really belong here . I'm just trying to find a fix for my tablet that doesn't involve the expense of returning it to Samsung.
I bought my Tab S 10.5 back in 2014, and until last year I felt that it performed flawlessly. So last year a friend of mine dropped it onto my kitchen floor resulting in a shattered screen from the top left corner outwards. I did look into getting the screen replaced at the time but it turned out that it was going to cost me £250, which I believe is half the price of what I paid for the whole thing when it was new. So I decided to live with the damage, which isn't too visible when its switched on.
A year later and I have what I think is a more serious issue. While I was on Facebook my tablet decided to turn itself off at 50% battery, and when I turned turning it back on it appeared to be stuck in some kind of boot-loop, constantly switching from a slowly glowing Samsung logo to the smaller constructing logo (I hope that makes sense). I tried various button sequences to get the thing running but none made any difference.
Following a bit of Googling I tried a hard reset and clearing the cache. The process took mere seconds, leading me to believe that the hard reset functionality wasn't working either. And after the reset where it gave me to the option to restart, I was taken back to the boot-loop again.
Part of me wonders if the tablet has reached the end of its life, but another part of me thinks that I should expect more from a 4 year old £500 tablet, although yes it did get dropped that time.
Anyway, I have been directed here by someone who suggested that a custom rom might be the answer, but after taking a look at the Samsung Tab S Development page, I am completely stumped at what rom to choose and how to install it, and just when I thought id go for it, I didn't really understand the following instructions:
Download the latest build (download to what, my laptop?)
Download opengapps.org (I dont know what this is and where to download it to)
Make a nandroid backup (totally lost on this one)
Recommended - Full wipe system/data (first install) (I think I did that, although it took about 2 seconds)
Flash latest Twrp (T800/T805) & Firmware from sammobile.com (T800/T805) (No idea what that means)
Flash ROM (?)
Flash Gapps (?)
Reboot
Enjoy!
Thanks for taking the time to read my post. I'm hoping that there might be an idiots guide to fixing the Tab S

1) yes, to your laptop or pc or what ever computer you're using.
2) OpenGapps are the google apps that don't come with a generic Rom, such as GMail, the Google Play Store, etc etc. (and again, download it to the computer you are using (so when you flash the Rom, you can flash these google apps also).
3) Making a backup (nandroid is one type, there are others), is imho, optional. If you have pictures, pdf files, anything on the device you don't want to lose, back those up somehow. I never worry about making a nandroid backup personally.
4) If you haven't installed TWRP, then you probably haven't wiped system / data. It's after having installed twrp that you want to do that wipe (within twrp, there are directions in it to do that). You wipe those partitions so you can "start new", with your new Rom.
5) TWRP is a replacement recovery you flash (install) over the old (original) recovery. It allows you to flash roms etc etc etc. BUT, you have to use the specific version of TWRP for your specific device.
I'd suggest doing a lot of reading, search google for various topics related to this subject; like 'how to install twrp on the Samsung Tab S' or 'What version of twrp should I use for Samsung Tab S' or etc etc etc.
Then READ READ READ READ READ READ!! until you feel comfortable with what you are doing! It's those that do things they don't have any idea what it will do that end up buying a new device when they didn't have to.
Cheers

That's great, thank you for your detailed reply.
Luckily I back up my docs and media to an SD card as I go, so I dont believe I have lost anything.
I will get reading this afternoon and fingers crossed it will work!
Further. I registered today and so assumed this was my first post, but according to my profile I posted in 2015!
Reading back it looks like those posts were made by me, but I have just registered under a totally different user name and password today and yet I am somehow logged in to my obviously forgotten account.

Following a bit of Googling I tried a hard reset and clearing the cache. The process took mere seconds, leading me to believe that the hard reset functionality wasn't working either. And after the reset where it gave me to the option to restart, I was taken back to the boot-loop again.
Part of me wonders if the tablet has reached the end of its life, but another part of me thinks that I should expect more from a 4 year old £500 tablet, although yes it did get dropped that time.
Anyway, I have been directed here by someone who suggested that a custom rom might be the answer, but after taking a look at the Samsung Tab S Development page, I am completely stumped at what rom to choose and how to install it, and just when I thought id go for it, I didn't really understand the following instructions:
Download the latest build (download to what, my laptop?)
Download opengapps.org (I dont know what this is and where to download it to)
Make a nandroid backup (totally lost on this one)
Recommended - Full wipe system/data (first install) (I think I did that, although it took about 2 seconds)
Flash latest Twrp (T800/T805) & Firmware from sammobile.com (T800/T805) (No idea what that means)
Flash ROM (?)
Flash Gapps (?)
Reboot
Enjoy!
Thanks for taking the time to read my post. I'm hoping that there might be an idiots guide to fixing the Tab S

That's great, thank you for your detailed reply.
Luckily I back up my docs and media to an SD card as I go, so I dont believe I have lost anything.
I will get reading this afternoon and fingers crossed it will work!

If you are having issues with your device then flashing custom firmware is not the answer.
If indeed it is software related then the best you can do is simply factory reset the device.
If that doesn't solve reinstall the stock firmware via Odin.
Don't put yourself under extra pressure by introducing unknown issues from flashing custom stuff.
Go to updato.com search your device, download the respective firmware for your device and flash it with Odin.
Google has countless guides how to flash with Odin .
If that doesn't fix it then it's likely hardware. The first thing you should look at for random shutdowns is replacing the battery.

Thanks. Luckily I haven't tried a custom rom yet.
No the factory reset didn't work, in fact it doesn't appear to work at all. The android guy is lying on his back with some warning text below it that vanishes to soon to be read.
I daren't try replacing the battery, as the last time I tied removing the front of a tablet (a mates) the screen shattered. Plus my screen is already badly cracked and likely to get worse if I attempt to remove it.
So ill look into the Odin option. Thanks!

I see you have to install more USB drivers to your laptop. Is there anyway this whole process might mess up my laptop?

No. Just install the Samsung usb drivers.
