Help Recovering from Failed Root Attempt (S7 Edge) - General Questions and Answers

So I tried to follow instructions to root my S7 Edge (model G935U).
It seemed to work, but after flash it got stuck in a loop with the logo screen. I tried it with both versions of Odin linked in the instructions, and neither is working. I've got to figure out some way to get it to working again. It seems I have three options:
1) Figure out how to stop this loop and proceed with the existing firmware.
2) Either use a different method to re-flash the rooted firmware, or find a different rooted firmware file to flash that will work.
3) Flash the stock S7 Edge firmware onto the phone. In this case, I am unsure which version to use as there are many listed on sammobile for my model. My phone is model G935U, it is unlocked, and it is the one designed to work with AT&T.
If I could get help on any of the following, I would be very grateful!
Thanks!

[Q] Bricked phone, need help unbricking. (System software not authorized....etc.)

So, I've done this before, and I've never bricked a device until now.
I tried installing a custom rom for my Galaxy S3 on Verizon, but when I restarted, it says this:
System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for help.
I can't get into clockwork, or any bootloader. Any attempt to do anything brings this screen up.
Now, I can get into the Odin downloader. (Power, volume down and home). But, I can't figure out how to get a Rom to load. This is where I am stuck. I have downloaded a few roms, all stock, but none of them want to be recognized. I have no idea where to go. I've been downloading stuff for 5 hrs and nothing has worked, so now Im going to the forumns. Any help is appreciated.
I have the Verizon i-535 Galaxy SIII.
You did not brick your phone you failed to unlock your bootloader. There are 2 guides in the android dev section for rooting.

Odin back to stock and next time after rooting make sure to use EZUnlock 1.2 to unlock the bootloader BEFORE loading a ROM

[Q] Galaxy s5 Odin and flashing

after towel was released at&t released a update which fixed the patch that was used to root in towelroot. I have heard that there are alternative rooting methods which I have tried that involve Odin. For some reason though when I try to use Odin it always told me fail and after a certain amount of tries in bricked my phone which is now in a boot loop. can someone help get me out of that bootloop?
I also have another question. Can't you just flash a older version of android to your Galaxy s5 and then use towelroot to root it?
(I am very new to this rooting experience and I would appreciate step by step guide):laugh:
Than you
You probably had "fail" message because you hadn't disabled the option "Reactivation Lock" in Security settings before using Odin.
To fix your phone, just boot in Download Mode, then flash a working firmware for your S5. Do you how to do that ? Can help you if needed
I also have another question. Can't you just flash a older version of android to your Galaxy s5 and then use towelroot to root it?
Yes you can, but prefer using newer version for you'll have better performance and security updates.

[Q] Can't update, downgrade, or rest to stock OS, PLEASE HELP

Good afternoon all if anyone could please help I'd greatly appreciate it!
So I just bought a Sprint Galaxy S5 from ebay with the assumption that with some customizing I'd be able to get the phone domestically unlocked. I got the phone and it was already updated to 5.0 Lollipop so I followed this tutorial to get the SSU.apk to actually work
http://forum.xda-developers.com/spr...locking-sprint-galaxy-s5-g900p-t3085624/page2
After a lot of time I was successful at rooting the phone and was able to downgrade to 4.4.4 but the tutorial calls for 4.4.2 but it seems that 4.4.4 was the only fw that would successfully install.
But now here's the problem I was able to obtain the domestic unlock code through Sprint but now the activation/update app doesn't work and doesn't open automatically the way that the reps said it would,. I've tried to reset stock through Kies but Kies doesn't recognize the phone. I've also tried to use Odin through out this process not only to reset back to stock but also downgrade the fw and the modem. The really annoying part is that small PDA/AP updates and installs work fine but when I try to Odin the original tars it always fails 100% getting a "sw rev check fail aboot fused 2 binary 1 " error on my phone.
I really don't know what to do at this point, and it seems the error is associated with a soft brick but the device still powers on and boots.
I thought this would be a pretty straight forward process but I've hit the wall and am losing my mind, I need help!
P.s. I flashed 4.4.4 fw with CWM and the device is still rooted
Thanks

[Completed] tmobile sgh-t999 s3 wont boot completely

I have a t-mobile s3 that was at one time rooted then updated to the latest firmware root was lost and never rerooted. I was running the latest update totally stock no modifications. The phone wont complete the boot it just hangs at the end where the samsung is going from blue to white. The phone will go into download mode and recovery however when i tried to do a factory reset on it it failed. The device is not rooted so i cant flash a rom to it. I dont know how to fix it. I dont know what version of odin to use and am not sure what rom to put on it or if i can even do it. I connected the phone to odin and it said s4 mini so I am thinking that is not the version of odin to even try and flash the stock firmware. any suggestions on how to fix my phone or if it can be fixed?
Hello,
Welcome to XDA.
I cant post a link for you but you can go to Sammobile or samsung-updates and use your model number to find your stock firmware. I'm sure there will be more than one android version for your device so choose whichever you want, just be mindful of which ones are rootable or not if you want to root it again at some point. Then use at least Odin version 3.09 or newer, make sure you have the newest version of "USB drivers for Samsung phones" installed.
If you have more questions or need further assistance you can post your question in the forum linked below.

If you're trying to downgrade then the only way to is use the rooted combo by jrkruse in the Verizon forums. That way you can actually get into the phone. Using safe strap there's a flashable zip that will remove any Google account tied to the device
