Unroot and Reflash AT&T Galaxy S7 - AT&T Samsung Galaxy S7 Questions & Answers

My Galaxy S7 will not boot to anything but recovery mode. I have tried the Return to Stock section of this guide, but Odin 3.12 gives me an "auth error" which says "Fused 4 > Binary 2" on the phone. The PrinceComsy version, meanwhile, gives me a "model dismatch fail" error. Is there any hope that I can reflash my phone back to stock?

Need more info about your phone. Firmware that is on the phone, firmware your trying to flash. What were you doing when all this happened.

Never mind, I got it fixed. I was trying to flash the G930AUCS2APF2 firmware, but the phone rejected it because it was a downgrade. I just flashed the G930AUCS4APK1 version, and it flashes and boots just fine. Sorry for not providing enough information; I'm new to flashing phones, so I was unaware about the downgrade. Thanks anyway!

[Q] Soft bricked after 4.4.2 update failed, please help.

Hey guys
I have a Hong Kong Note 3 N9005. Yesterday I flashed the 4.4.2 sammobile update to my phone using ODIN 3.09. I had auto reboot and f.reset ticked. The ROM was put in AP and I hit start. Then I received the error Invalid ext4 Image. Turns out that Hong Kong versions of the N3 cannot install European ROMs. Since then I have not been able to boot my device into android. I just loop into download mode telling me it detected a firmware update. Kies was no help.
The update DID update the bootloader, so now I cannot go back to stock ROM. I have tried a few things. I tried flashing the stock Hong Kong ROM MK1, it fails. So i found a guy that fixed a similar problem buy removing the aboot.mbn file and repacking the ROM. Tried that too and the ROM flashes but it leaves me in a bootloop. Phone turns on says booting recovery then restarts. I also tried cf-root in an effort to flash another ROM still not working. I cannot get into recovery mode no matter what I do.
It seems I have run out of ideas and am reaching out for help.

Hello thanks for replying.
Only problem is I cannot get into cwm or twrp. Any advice on what I can do to try to get CWM or twrp working? I can flash with ODIN. But with the CWM I tried it still just boot loops and does not allow me to get into recovery.
Thank in advanced.

Same Issue here. I tried to install the 4.4.2 N9005XXUENA6_N9005OXXENA5_N9005XXUENA2 update on my Note 3 via odin 3.09.
Got an ext4 update failed error.
After this, the phone's bricked and is stuck on the Kies Recovery Screen. I tried to go into recovery mode in Kies, but it says this model does not have initialization.
I tried installing a 4.3 N9005XXUDMK3_N9005TNLDMK1_N9005XXUDMK2, but again failed. Download mode shows SW REV CHECK FAIL : [aboot] Fused 3 > Binary 2
Can someone please guide me to unbrick my phone?
I don't know what ROM I was on initially. It was the stock ROM that came with the phone.
I dont have CWM and TWRM installed.

Got this response from MrAndroid12 in another thread I'd started:
"This is not a brick at all. Just add a .pit file and restart the upgrade via Odin again.
You should be fine."
I don't know how to add a .pit file though.
I am certain the bootloops are because it flashed the new bootloader. I think your best option is to wait for a dev like indie to release Omega V7 and try to flash that through Odin.
Or if you can extract the different partitions from the original thread you can try push them one by one with Odin.

It is the bootloader yes. But it NEEDS the bootloader to be able to boot in to KitKat. And there is no downgrading once you've installed the new BL.
Best option is to re-flash via ODIN again and not wait 2 weeks for a Dev to modify a custom ROM...

Soft bricked Note 3 tmobile

Once again i am here looking for help. I was flashing the stock firmware to my Note 3 via odin and something must have gone wrong. It said failed after writing some of the file to the device. Now i am in a soft brick with no recovery. I am only able to get into download mode. I have tried reflashing the firmware via odin but it fails after getting a failure to write error. Is is possible that the phone won't accept the file because maybe the usb debugging option was reset? Phone says this is read letters after the failed download. SWREV checkfail sb(1)fused 2> binary 1. If anyone has any ideas or a link that would help, i would greatly appreciate it.
Mostly fixed.

So was able to flash twrp via Odin and then reboot into recovery and flash my backup of CM11. But odin never wants to flash stock firmware for me. I like CM but i use the s pen to much so i wanted to go back to rooted stock. Any ideas on why odin isn't working for stock firmware? its still fails after a few seconds. Anyways atleast i have a usable phone for now.

1. You should give us the problem/failure message from Odin so we can read why.
2. You're on the wrong forum if you want N900T specific help.
3. You can always flash a new TW ROM from TWRP

"SWREV checkfail sb(1)fused 2> binary 1" usually means you are trying to downgrade something in a way that Samsung/T-Mobile does not want you to.
Most likely you need to download the latest firmware (and not the old one):

How do I unroot and reflash stock ROM onto AT&T G930A S7?

I am trying to unroot my phone. I have a US version of G930A. Sammobile has every county except the USA. I found G930AATT1APB5_User_Binary.zip which has AP_G930AUCU1APB5_CL7193387_QB8719495_REV02_user_low_ship_MULTI_CERT.tar, the BL, CP and CSC file in it. I try to flash it using Odin3, and I get an "odin protocol version error." I take it because the image is a lower version that's what's on there. I would like to download the latest stock image but sammobile doesn't offer images for the US? Or is there a better way?
Wrong forum. This here is for SM-G930F Development, not Q&A. You'll get the answers you're seeking and more, at the S7 AT&T Q&A and Dev forums. Mod, please move - thanks.
Wrong forum. But try using Kies in Download mode
That is what i do when ever i restore my phone.
No Kies good lord. This isn't a Note 2.
You're getting that error because you're on newer firmware than you're trying to flash so it's erroring out.
Follow the Return to stock procedure in this thread:
http://forum.xda-developers.com/ver...sed-unroot-t3411039/post67605246#post67605246
Flash all 4 files, then you'll be on PF2 and able to get the OTA Update to PG1 with wifi calling, etc.
I tried using kies. It asks me for my model. I put in SM-G930A. The serial I put in all caps and it tells me my model number I entered is wrong.

Which Odin are you using?
You're flashing the PF2?
I've tried many versions of Odin v1 (not the 3). I'm not sure what the PF2 is.
To get it to work, I just defaulted the phone and rerooted it. It's the only way I can get it to work. It's working perfect right now. Only question is how long,

for g930a (galaxy s7 at&t NOT EDGE)
WARNING: YOU WILL LOSE ALL DATA MAKE A BACKUP
download these files:
Odin: http://www.mediafire.com/download/2t...din_3.12.3.rar
Flashing Files: https://drive.google.com/file/d/0B17...w?usp=drivesdk
After downloading extract the .rar extract it then extract each, BL, AP, ect... files. Use the odin included in the download to flash and you will be returned to stock. If the odin included still gives you the error you can get the princecomsey version and see if that works from here: http://downloadandroidrom.com/file/tools/ODIN/ODIN-modified.zip
If odin freezes or crashes just restart it and try again, it might take a while foor the AP file to load into odin so just be patient and if it looks like it is about to crash wait about 2-3 minutes then force close it and try again.
Now you are returned to stock an all set !!
(p.s) - PF2 is the latest firmware as of now for the g930a, meaning when you flash this you will be all set. You may have tried to flash the original PF which is now outdated cause AT&T updated it, I did this and it worked but i could not update my phone so I flashed this one and it works perfectly and Samsung pay is up and running.

An error has occured while updating the device software

Hi.
I am currently stuck at a blue screen that says "an error has occured while updating the device software." I rooted which went fine, but when I went to add TWRP I was unable to access recovery. Each time I would try to access recovery it would say something like "system software not authorized by ATT has been found on your phone." So I decided to revert back to stock using Odin and the firmware from Sammobile, that however failed and now I'm stuck on the "an error has occured while updating the device software."
- I can get into download mode
- I can NOT get into recovery and havent been able to since I rooted
- I had just upgraded to 7.0 ota right before I rooted
- I've tried flashing with Kies however it just keeps asking me to enter a model number
- I've tried flashing with Smart Switch but after I enter the model number and serial number the app closes and nothing happens
- Odin fails everytime, have also tried patched Odin which I used to root and fails as well
Edit: Could it be that I need to flash 7.0 firmware instead of 6.0.1? I read something about the bootloader not allowing downgrades?
Please help?

Why would you try installing TWRP on a AT&T S7 Edge which the bootloader is locked, that's one reason you can't go to recovery, basically you bricked your AT&T S7 Edge, try to odin Stock AT&T S7 Edge Nougat see if that gives you recovery back, and do not try installing TWRP again, if your able to Odin back to stock, good luck!

I'll try that. And why? My own incompetence I suppose....however I couldn't access stock recovery after I rooted either, before I tried to install TWRP, so I'm not sure how that factors in?

that error means that your device is in "binary 1", and you are trying to install a binary 0, so make sure you have the latest firmware.
Try unchecking "BL" in Odin and then flash.
this occurred to me after flashing LineageOS 15.1 and getting Root from stock Oreo 8.0.
