Hello, I'm looking for help unrooting. I have a T-Mobile S6 Edge +. Here are screenshots of what it's running. I can't find T-Mobile SM 928I firmware. I am also having issues getting Odin to run on my new laptop...I feel like I've tried installing 100 different drivers, with no luck! I know there is as mobile Odin app I'm willing to try if I can find the right firmware. Any help is appreciated!

First of all install these drivers after that download odin3
Download your firmware file from updato.com or sammobile
Download firmware for ur model and remember doesn't matter from which country or carrier you get its important to be your model (g928i) extract the firmware zip put it in AP click start after that wipe and see how it goes
BTW wrong section should've posted it in q&a
Hello,
It's been a long time since I've been these to these forums and an even much longer time since I last had to modify any kind of software on a phone. I recently upgraded to an S7 edge on Sprint and would like to know where to find the tools, roms, and files needed to go to the unlocked firmware version for the S7 edge and go back to Sprint's stock firmware if need be.
More importantly, I'd like to know what risks I encounter especially with Samsung's KNOX. Again, it's been a while so please don't flame.
Any information or direction is very much appreciated.
Thanks in advance!

There's not much for roms echoe is pretty nice. It lags pretty hard but theirs a fix http://forum.xda-developers.com/verizon-galaxy-s7/how-to/guide-to-fix-s7-lag-root-s7-variants-t3441715
As far as firmware your somewhat limited as well depending on your current firmware you may only have the latest 935p and 935U to choose from.
P.s you don't have to worry about tripping Knox I've flashed xposed govtuner viper modified Odin tars that failed miserably I'm still 0x0
Thanks for getting back to me vegoja. So as far as flashing the firmware, where can I get the necessary files? I've seen some threads mentioning or linking the ROMs so I think I'm okay there. Also, I think I'm supposed to use a special version of Odin, not sure why. Lastly, where do I get all those other necessary files like the CSC etc.?
Thanks.

Once you flash the U firmware, you can't currently go back to sprint's firmware. Something to do with the upgraded bootloader. But the U firmware is stable and smooth and has good battery performance. You can enable hotspot to without root which is a perk.
Odin: http://d-h.st/gsDA
935U PI3: https://drive.google.com/file/d/0BzXeLw4AsxZHZlM1OTJZYXBOQW8/view
Flash AP, BL, CP and CSC (not Home_CSC).

Hi nghia0423 and Soooperstar,
Thanks for getting back to me. So to make sure I have this correct...I can flash a 935U firmware on my phone and go back to Sprint stock firmware, but it has to be PJ2.
If this is the case, then I have a few additional questions if you don't mind. First, do the AP, BL, CSC, and CP files differ between firmware versions? If so, where do I get those files for each version?
Second, if I go back to Sprint stock firmware PJ2 (which I assume is located here: http://forum.xda-developers.com/spr...rmware-g935p-pe1-official-sprint-6-0-t3414654), will I then be able to follow the standard firmware upgrade path by allowing system updates and going through the standard update process?
Lastly, is there some risk I'm missing or haven't addressed? If I go to unlocked firmware I want to make sure I can always go back to the current Sprint stock firmware.
Thank you again for all the help and information!

Both pathways - 935P firmware & 935U firmware - offer updates via OTA. They're both official Samsung pathways. As of right now, the 935P pathway offers more frequent updates (monthly) opposed to 935U's mostly every other month update cycle.
The most current firmwares on the 935P & 935U pathways are on the same bootloader version. Therefore, one can flash back and forth with no issues. I recently came to PJ2 935P from PI3 935U so I could download the Nougat beta.
The benefit of the 935U firmware is the lack of bloatware which leads to higher performance, smoother UI, better battery life, and easy to add Hotspot functionality.

Hi optimummind,
Thanks for letting me know that I can flash back and forth between Sprint's firmware and the official unlocked firmware. I did have additional questions. Are teh AP, BL, CSC, and CP files different for each firmware version? Where do I get them?
Thanks!
I purchased this phone a while ago and I have Straight Talk and don't have any updates of any kind through it since around September. I'm assuming it's because the phone is not directly with Verizon. I've rummaged through everything and seen the possibility and instructions for installing the update.zip onto the SD card and trying to manually install it but the install fails saying it's trying to find a newer version of the installed software.
I currently have G935VVRS4APH1 on the phone and it's looking for a newer version of the software. Is there any way I can work around this?
My last phone had CyanogenMod and I enjoyed it (RIP) but I'm not really all too keen on dealing with rooting and installing a ROM on this phone because... it works. It works now... but it's about the security concerns and about newer features.
Any help?
with straighttalk you will never get updates you will always have to do them manually with odin heres the link for the files you need https://forum.xda-developers.com/verizon-s7-edge/how-to/odin-stock-nougat-firmware-t3570156
you can use either the Samsung U-variant(less bloatware) or the normal Verizon both should work fine just flash it through odin
heres the link for odin I forgot my bad

Many thanks. If I have questions I'll return.
No problem glad I could help let me know if you have any issues
Greetings pals i have a really big question, i got a S7 Edge from AT&T (SM-G935A) but i cant update to nougat so i flash the unlocked (SM-G935U) firmware to get Nougat so i just wanna go back to AT&T but i cant via odin i downloaded a lot of firmwares labeled to 935A but when i try to flasg via odin it stucks at File analysis and thats it, also i tried with another (older) version of odin and it gives me a soft brick the main cause i want to go back to AT&T its because i want to try Oreo Beta but im stuck
Any help would be appreciated and if something its wrong with this let me know
Hi,
I am trying to flash my SM-G935A AT&T S7 Edge (not carrier unlocked) with the new SM-G935U firmware (G935UUES4CRG3/G935UOYM4CRG3/G935UUES4CRG3/G935UUES4CRG3) that I dowloaded for my US AT&T S7 Edge. I upgraded my S7 Edge to the latest Oreo firmware via OTA around a month ago.
I used SamFirm to download the image to flash. Anyhow, even though I put every file into its respective category on Odin 3.13.1, I get an "SHA256" mismatch error. I've seen some instruction that say to only add the AP file onto Odin and others say to use the prince cosmey version of Odin. What could be the problem? Does the phone need to be carrier unlocked? Is my firmware too new or of the same version? Do I need to use the prince cosmey version? Is it not possible to flash the g935u firmware onto a g935a phone? Should I use another download source? Should I use the slightly older G2 firmware? Anything else I should consider?
Also, I noticed that I could not download firmware for the SM-G935A using the ATT code with SamFirm? Any reason as to why?
I realize that there are many other threads that touch upon this problem but they are either with a different edition of the phone, firmware version or some other variant. I'm posting a new thread because I want to be as thorough as possible and make sure not to brick my phone by receiving safe advice before moving forward. Thank you for your time!
Below are the SamFirm download details:
SamFirm v0.3.6.0

Correct Thread?
Did I post in the wrong thread or something? Is that why there is no response? Would someone be kind enought to point me in the right direction if this isn't the right section for such a question?
Thank You
Hi did you find any answers to this issue? i got stuck on same point as you...
Stock Odin checks the version on the device and fails because the U version doesn't match the A version you are "upgrading". There are patched versions of Odin that skip this check, and that is what you need to do a cross-carrier upload.

Use a patched odin to flash the firmware, it will go through.
