[SM-T837V][Combo Firmware and Stock Firmware Files]

Hello Folks!
As soon as I got the tablet I spent a good few hours looking around for the combo firmware to start looking for exploits so figured I would provide you guys with a link to the firmware for free
It was quite funny actually, after I soft bricked and got stuck in a boot loop I realized I couldn't find any stock firmware anywhere either haha, so I spent a few hours looking for that as well.
I have the Verizon variant, I am not sure if it will work on other USA variants or not as I have no way of trying. With that being said, below will be the links. I will provide a rev1 combination firmware and a rev1 stock firmware as well as a link to a modified ODIN for easy flashing!
And with all that being said, the combo firm is good to bypass FRP. You can enable the oem unlock switch but other than removing FRP it is useless as of right now. You can however, mix and match the firmware unlike my S9+. I am currently on stock firmware with a permissive boot.img for example.
If you got questions or need help, well, you probably shouldn't be downloading anything or flashing haha. But I will try to help when I have time. I do not have any current plans to keep this thread going with updated filese as I had to pay for these. If I can find em free moving forward I will re-upload if I can but I typically stay on the lowest rev/firmware I can until I find a root method
T837VVRU1ARG4 COMBINATION FIRMWARE/FACTORY BINARY
T837VVRU1ARGG STOCK FIRMWARE
MODDED ODIN v3.13.1
If you feel like buying me a beer...​

What is the main benefit of this?

In the q&a section someone wrote it is readily rootable with Magisk. Is that not the case?

@elliwigy
Is there any firmware for the unlocked LTE snapdragon. I got the Verizon version but it's not playing nice with AT&T. Any ideas? Maybe flashing the unlocked firmware would help.

I think it's just the tablet, my Verizon one isn't playing nice with my Verizon service. Constantly not switch towers and losing service when full service is available. Or it's a tower problem but my note8 doesn't do it when my tablet does

Thanks for this, have been looking for a couple days for the build.prop file.

If you get permissive boot, try adb verity disable and mod through push pull adb style like we did on Att note 5

Will this work on sm-t817v?

I actually had a 817v. They called it the pro version. It was just an updated version at the time.

OEM Unlock
I have the T837V and would like to ODIN flash your files, but as you know there is no OEM unlock in the Developer Options on this tablet. Are you saying that you can flash these files without enabling the OEM unlocking?
I would like to install TWRP, but I believe this is not possible without enabling the OEM unlock. Do you know if this is true?
Thanks

Forgive my apparent noobishness but what exactly will that do? Looking for a way to root and wanna know if u have found something I haven't.
Flash firm then what? Does it make OEM show or what? I just happen ta have the most difficult version of the tab S4 which is SM-T837V

I am currently working on a root method with the N9 but it should also work on Tab S4 once all is said and done. I actually found the exploit I use on the Tab S4 originally before I started workin the N9. Nothing is released yet as so far have only gained root on S9 Exynos and I am currently super bricked and waiting for a device replacement lol
Flashing other carrier firmware won't help you unlock any bootloaders or anything nor will it necessarily help you root. Only benefit I can see really in flashing other carrier firmware is say if you have an sim unlocked tablet (we'll say it's a Verizon tablet) and you want to use it on say Sprint. You can flash the Sprint software in ODIN and everything should work. It would be like you purchased the tablet from Sprint essentially.

Downgrade to emui 5

I got a Huawei mate se and didn't realize that allowing it to update to Android o would block the bootloader unlock tool. Is there anyway to downgrade my firmware so I can unlock my bootloader?

There is a roll-back ROM on firmware finder. As long as it shows your IMEI as approoved, it should install.
That's the nice clean way.
There is a dirty ( possibly dangerous way ) by using the nougat service ROM. That ROM is for bnd-L21, so not sure how an unlocked bootloader will handle it. It has worked on unlocked before.

The mobile app as far as I can tell doesn't work on newer versions of android. They even have a disclaimer mentioning that the app only works for older devices now.

You are not on 8.1, the app can work.
But I was only referencing the app for the guides linked inside.
You should be able to use it to flash b330. Which should work in DC

My bad I am on 8.0 to be specific bnd-l34 8.0.0.341(c567) and as much as I've tried I can not get it to work on the phone following along on the videos. They are using the app on emui 5.0 not 8.0. It doesn't work anymore on 8.0

All there videos revolve around emui 5.0 or lower. It stopped working with 8.0

Because the locked bootloader, you can only use the firmwares that are approoved.
Chances are , the only one that's approoved is the b330
And if not , then only option is the service-rom. Followed by dc-unlock, then the hwota and correct ROM
It has been done.
There should be confirmation back in the mate thread somewhere.

This post you made here sounds doable.
This service rom so far has been only thing we found that will load with three button method (dload)
But it is not a full rom to keep on device. It needs you to follow up with flashing fullOTA of your correct version after.
https://www.androidfilehost.com/?fid...83647474828964
1. Unzip download
2. copy the dload folder to root of sdcard
3. power on phone holding all three buttons
4. After phone finishes and reboots, unlock frp and bootloader, if needed
5. Use Huru or HWOTA to flash correct firmware for your model/ region.
Enlighten me what is huru or hwota? If I were to flash this does it boot up into android or is it non functional?

Yes, this should leave you able to boot. And with build level that should allow DC unlocked to give you the code.
Remember like I said before this is kind of a dirty way around and 'could' have issues unknown. Like what if DC does not give you a code, you would then be stuck . (Though you are stuck now)
Huru and hwota are very similar. They both use TWRP to give custom flashing control.
Hwota uses modified stock recovery to flash full ota files.
Huru repacks full ota files so that TWRP can flash them.
Since doth start with TWRP , bootloader unlock is needed.

Just spent most of the morning going back and forth with someone else with mate see, and they just did restored his device with the service ROM.
I do not now what he was restoring from, but he ended up with "unknown model" and default build number of 8.0.0.46
This is because of (probably) some data corrupt issue making the flash go bad. But he was able to run the ROM and unlock boooader.
Difference is he already had his unlock code.

Have you seen this guide?
It is for "official" hisuite roll-back
I have not rolled back so do not know it it works though.(I checked with my device, it shows no downgrade available)
I know the roll-back firmwarm listed on firmware finder was listed as "bond" and not "bnd". So this means not available "officially"

[Question] Bricked A5 2017?

Hey, recently I booted up my phone and it said custom binary locked by frp lock, or something along those lines, since then I came a lot further/closer to fixing it. As now when I boot it up says: An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software.
When i try to download/reflash new software it fails because it's blocked by FRP lock, anyway to fix this?
Thanks in advance.

No, because I get blocked by the frp lock

Extract the firmware with a different archiver.
Ensure the download hasn't been interrupted and download it with something else.
Otherwise, the firmware might actually not be original. It has to be a stock touchwiz/samsung experience rom to pass FRP (in Odin). Not a custom rom.

Thank you for your effort to help me but the exact problem im in is thus. j337r4 is frp locked to my old gmail that was hacked so i abandoned it and made a new one. I have yet to find a method of frp bypass that works on this one so i resorted to combination rom, however none of the combination roms for this exact model j3 that i can find have worked. they dont even flash, odin fails them after 10 sec and phone has new red message under normal download mode message that says "sw rev check fail" in red and that current binary is u4 but the only combination roms i can download free are u1 and u2 binary.

"only official binarys are allowed to be flashed" because the bootloader locked. you must unlock the bootloader first.

mate my bootloader was unlocked.
i have 4 rooted phones i know how to unlock a bootloader.........................
it wasnt the BL it was the method provided that didnt work.
this a50 drove me to the point of being psychotic.
the phone is now gone due to almost being thrown at a brick wall.....
anyways in future someone should do a guide for the australian varient as none of these methods worked for it.... and believe me i tried all these methods even with overseas firmware etc. :good:
