My company issues the Verizon flavor of Galaxy Tab 4 8.0 for our users that are out in the field. It seems like this one particular user (or someone close to them) decided to try and root the device in order to get around the restrictions we have on them via a MDM client. When the tablet boots (even when trying to go into recovery via power+home+volume up) it goes to the triangle screen saying "System software not authorized by Verizon Wireless has been found. Please turn off and go to the nearest Verizon store". But unfortunately the store turned us away saying there's not much they can do. I am able, however, able to get it into download mode.
So far I've tried flashing the Verizon Stock 4.4.4 firmware, which I found searching around here, via Odin 3.10.7. It gives every indication that the process completed and shows the green "PASS" block up top. When the tablet reboots from flashing, it still goes to the triangle screen. Once the triangle screen comes up, upon reboot there's a lock at the bottom of the boot screen and the word "Custom", shown here: http://i.imgur.com/5PC0qeZ.jpg. It seems like maybe the bootloader isn't correctly being overwritten or something. When the tablet is in download mode, it says the following in the top left (after I've already flashed it a few times):
Odin Mode
Product name: SM-T337V
Current Binary: Custom
System Status: Official
Reactivation Lock(KK): Off
Qualcomm Secureboot: Enable (CSB)
RP SWREV: S1, T1, R1, A2, P1
Secure Download: Enable
UDC Start
I'd like to think I'm not a total novice with this stuff, but I'm at a bit of a loss at the moment. Where should I go from here? I've read from a different thread about the note 3 that sometimes you have to flash the .pit file again in order to nuke the partitions, but so far I haven't been able to find one I feel comfortable enough to try.
Hi all members of xda, sorry for my bad english, i will try to explain what exactly is happening with my phone.
I power it on, it`s vibrating and appear "Samsung Galaxy S5........POWERED by android", and that`s all, it continuously restarts itself until i remove the battery.
I can`t enter in recovery mode, it`s restarting from there continuously too... In download mode i can enter, and there at PRODUCT NAME it says is SM-G901F, but under the battery is SM-G900F.
In download Mode this is all what it says: "ODIN MODE (HIGH SPEED)
Product Name: SM-G901F
Current Binary: Samsung Official
System status: Custom
REACTIVATION LOCK: OFF
Knox Warranty Void: 0x0
Qualcomm Secureboot: ENABLE (CSB)
RP SWREV: S1, T1, R1, A1, P1
Secure Download: ENABLE
UDC START"
This is all.
So, i think that boy from who i bought the phone tryed to root it or flash it with another rom?
Can anyone help me please? Thank you.
What it says the model number is when in download mode is what needs to be believed. There seems to be a lot of this lately.....devices being marketed/sold as the more popular 900F variant when they are not.
You have to get the correct firmware from sammobile or samsung-updates and flash it with odin. I doubt it's the person who sold it to you as apparently nothing can change the info in download mode, and the sticker says something else. The seller may have tried to flash a 900F firmware, but that is probably all he's guilty of......

Thank you @keithross39, i flashed it but for the first time when he booted up, he passed the "Samsung Galaxy S5....Powered by android" screen, appeared T-Mobile and then he restarts again...and it don`t work yet....keeps restarting itself...
I have and printscreen with odin when it passed but i can`t put it, after 10 posts only.
So what can i do next? Any ideas? Some roms? Thanks.
Try accessing recovery now you have flashed (Vol up, home and power keys together) and wiping cache and/or wiping data/factory resetting.

@keithross39, appears in left up corner Recovery booting... but its restarting, doesn`t enter in recovery menu...
Can you tell me which version of Android you flashed?......
http://i.imgur.com/rVnFwJM.jpg
This one DTM-G901FXXU1BPA2-20160125170733 @keithross39
5.0.2 from Germany (T-Mobile).
Try flashing this........

It IS for the 901F, but it's what the hosting website calls a 'repair' firmware.
So it is supplied as separate files that have to be loaded into their corresponding 'slots' within Odin. I'm guessing it will be unbranded too. But being a repair firmware, it stands a better chance of successfully flashing and booting than a normal firmware.

Just finished to flash it and still keeps restarting, didn`t worked @keithross39
What about recovery now, can you access it and do the wipes?
http://i.imgur.com/rVnFwJM.jpg
No, keeps restarting... What if the owner accidently flashed rom for G901F but the phone model is G900F? It can be?
Download mode says 901F.....
AFAIK the info in download mode is hardcoded into the device and can't be changed.....
I can't see how it'd be any other variant....
http://i.imgur.com/rVnFwJM.jpg
Ok, so what i can do more? With box maybe it can be done? Or you don`t know @keithross39? I am very greatful for your time.
So far, everything you've tried would have put your device back to stock and wouldn't have affected knox.....
Knox is regularly used by Samsung to assess whether your device receives a warranty repair. As long as knox remains at 0x0 (as seen in download mode) your warranty is intact.....
Going custom is your only other option and that will trip knox and void your warranty. I can suggest how you can go custom, but it's up to you whether you want to torpedo your warranty when the ability to flash your device successfully is in question.
http://i.imgur.com/rVnFwJM.jpg
@keithross39 the warranty expired. If you say that custom rom will make it work, i say let`s try it...
Don't get me wrong fella....I'm not saying this WILL work.....
There is an element of risk whenever you attempt to modify a device. As I said, I can provide you the information that *should* set you along the correct path, but at the end of the day there are never any guarantees, and it's down to you whether you want to take the risk or not
http://i.imgur.com/rVnFwJM.jpg
Ok, i understand mate, i will take the risk, anyway what can go more wrong...
Lol....don't even *think* that sort of question, let alone type it on a public forum......
Ok....here goes, but first, the usual disclaimer....
"This information is provided for information only. Neither I, nor anybody else on XDA is liable if you choose to undertake the processes set out below. By choosing to complete the steps below, YOU are assuming responsibility for the working (or otherwise) condition of the device when the processes have been completed"......

Get your TWRP from here.....
http://forum.xda-developers.com/galaxy-s5/development/recovery-team-win-recovery-project-t3110930
Get your SuperSU from here.....
https://download.chainfire.eu/696/supersu/
Follow these instructions.....
1) deactivate 'Reactivation Lock' (can be found under Security in Settings).
2) copy SuperSU zip to your device/external memory card.
3) boot into download mode.
4) Odin flash TWRP.
5) DO NOT allow phone to boot, (uncheck auto reboot in odin and if necessary remove the battery as soon as the TWRP flash has completed) then.....
6) boot directly into recovery. (Vol +, Power & Home button combination)
7) flash SuperSU zip.
You now have root and can flash your choice of custom rom for your device.

@keithross39, how can i make step 1? And i don`t know how to make step 2 neither... :-/
Step 1 can be (at least) checked by booting into download mode and reading the info on the screen. In your first post, your info showed that reactivation lock was off.....hopefully that hasn't changed.
Step 2 requires a micro SD card. You copy the SuperSU zip to that and put it into the phone.

Hello everyone!
I need a little advice to fix my softbricked note 4
So here are the facts:
I boght a bricked N910F i tryed different roms from sammobile using odin and twre, more than 7 to be specific, and most of them did t work as it shoul. My imei was the same as on the case but i noticed SN was different in system and knox 0x1.... I got a version of android 6.0.1 to work but there were different little, big problems like not rememering wi fi passwords, fingerprint not working version :null in testing, and often restarts and bootloops after installing different aplications. i tryed many things even repartition with proper pit file, i still had back-up of my efs but considering the serial number was screwed up i gave up trying anything else. I tryed rooting with different methods but everything failed.
I boght another N910F with screen broken but working mainboard and knox 0x0
Swaped the mainboard, tryed samsung kies 1, entered serial and model and it gave me the fw i needed to flash. Tryed flashing with kies and at the middle of transfer it said failed and phone froze, didnt even power on for a while. Tryed again after a few howrs, same rezult with message emmc read fail, and at the bottom emmc write fail.
kies said i need PDAG2/CSCE2 / PHONEE3 CNX
Now, later in the evening i managed to power it on agan and i dont know what to try so i dont screw up with knox
Here are some pictures of my current status:
Current status: cant post picture...
ODIN MODE (HIGH SPEED)
PRODUCT NAME SM-N910F
CURRENT BINARY Samsung Official
System Status Official
REACTIVATION LOCK OFF
Knox 0x0
qualcomm secureboot enable csb
RP SWREV S1 T1 R1 A1 P1
secure download enable
UDC STAR
"Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again"
What should i try next?
Thanks
Later Edit:
looked up on youtube and found that smart switch can do the work, tryed it and seems it went all the way and installed proper rom without fail. LOL
Morning edit:
So everything worked perfect last night so i left it on fastcharger. In the morning i found it in download mode with dii emmc read fail, could not do normal boot.... After this i have to let it rest a bit without battery, then it boots up ok, works a few minutes then it shuts down and never wake up

I found the only way to keep it working is by preventing it to go into sleep mode. Play music on repeat muted keeps it working
Lucky i have fast chargers and 3 battery
i tried different keep alive apps but they eventually fail and phone dies
A while back my friend gave me his tablet to try and fix. He was screwing around in odin and did a nand erase. From my research it seemed I needed a pitfile to fix it. This weekend I was clearing out some junk and found the tablet so decided to give it another try. I was actually able to finally find the pit file, so I downloaded odin, the pitfile, and the newest lollipop. In odin, I loaded the pit and selected repartition. Odin goes through the process, reboots the tablet to the little android guy it loads then reboots again and it hangs on the Samsung Galaxy Tab 4 screen and won't go any further. I can access recovery and download mode still and according to the recovery logs the OS installed and is there, it's like this thing isn't setting the boot partition correctly or something. Anyone have any experience with this, or able to tell me if I'm doing something wrong.

IT'S JUST A ROLLER COASTER OF EMOTIONS!
Alright, I've had this thing since 2015, it's in pristine shape since it's lived in an Otter Box all it's life, so I'm hoping it can be brought back from the dead.
A few weeks ago, it suddenly went into a boot loop. Phone is un-touched, just running random Play store apps and Nova Launcher (wouldn't even have that if TouchWiz hadn't kept crashing one day).
Thought I would be a smartass and fool around with the safe mode setting, etc. Well, apparently I did something very wrong, and ended up with an error message like this:
ODIN MODE (HIGH SPEED)
PRODUCT NAME: SM-N910A
CURRENT BINARY: Samung Official
REACTIVATION LOCK: OFF
KNOX WARRANTY VOID: 0x0
QUALCOMM SECUREBOOT: ENABLE (CSB)
RP SWREV: S1, T1, R1, A2, P1
SECURE DOWNLOAD: ENABLE
UDC START
Figuring I had probably broken it enough, I dropped it off at a repair place. They said they'd poke around, no guarantees. Week later: no joy, couldn't get it to work. I resigned myself to the fact I was out a phone and would need a replacement. A friend of mine recommended popping onto here and trying to download...a thing? I forget, some acronym that would reset it to Samsung's defaults.
So, I plug my phone in via USB, hit the power button.......AND IT'S ALIVE. Like it's a fresh build. Enter in my google info, run through some setup steps. I figure all is accidentally well. But now it's dead again. Screen won't turn on, though Windows tried (and found) some USB drivers.
It seems like it wants to work, but....won't. Maybe it's being moody, I dunno.
Any thoughts?
If you want to try to recover and start 100% fresh you can go on sammobile.com and download the latest software/firmware for your phone as well as the program ODIN. The site has instructions on how to load it onto your phone. As long as you have download mode (power, volume down & home button once phone off) and a charged 80%+ battery you should be good to go.
This would wipe EVERYTHING on the phone though.
