How do I unroot and reflash stock ROM onto AT&T G930A S7? - AT&T Samsung Galaxy S7 Questions & Answers

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.

[Q] trying to revert sm-n900a to stock.

Wassup guys, ive been searching the forum for going on three days now trying to revert back to stock. i keep getting fails through Odin 3.09 and 3.07. Crazy thing is that i have a baseband of mj5 and a build number of mi9. Im on my last nerve with this. Had the phone since Oct. and love it to death. But right now im ready to take it out and practice shooting. Im a fairly knowledgeable with odin and flashing in recovery but this has me at a stand still. Any help as soon as possible would be greatly appreciated. I have downloaded the MI9 files for odin (BL, AP,CP,CSC,PIT) for MJ5 i have (BL,AP,CP,PIT). If im missing some files or doing something wrong a link to a good tutorial would help. Thanks
Just tried flashing mI9 firmware in download mode and got SW REV CHECK: (sbl1) fused2> binary 1
did the whole *#1234# and got AP Mj5 and CP MI9
Confusing.
Be more clear instead of shooting the phone.
What custom rom you were on, if i understand you correct? Android version and your firmware?

No custom rom, 4.3 Baseband says MJ5. Build number says MI9. i dont know if they are supposed to be the same. I was rooted and unrooted. Just trying to get it back to days 1, fresh out the box, Bone stock.
Ok i did the *#1234# now my AP is N900AUCUBMI9,
CP is N900AUCUBMJ5,
and my CSC is N900AATTBMI9.
this is confusing the hell outta me. in the earlier post i didnt have a CSC. only the AP and CP.
Flash a newer firmware or same as your last firmware. I assume you can't downgrade to the original firmware if you have updated once to a newer one as bootloader gets locked.
Or flash 4.4.2 with Odin 1.85

I have tried that also. I dld the N900AUCECMLG.zip for the phone but when i unzip it im at a loss for what to do with the files. i dont know if it should be done in recovery or what files to use with odin. I dont see any tar or md5 files.
You have [email protected]? If so this is the correct firmware for you.
http://www.sammobile.com/firmwares/3/?download=25106
From there you can see instructions to how to flash. Read carefully. Don't panic.
Download rom. And use e.g winrar ro open just once when the files are downloaded. You are extracting twice and stop doing so. Open onse and drag and drop files to your e.g desktop. Once you do this you get md5.
You put the phone into download mode when flashing firmware. Turn it off. Volum down+home+power button at same time when asked if you want to continue press Volum up. Then you are in download mode.
Why do you even flash anything if you can't basics. Read more. If you still can't do this all before attempt or ask a friend to do it for you.

Is there a way to update baseband but keep root?

Hi,
I rooted my S8 (SM-G950U1, carrier unlocked) recently using SamPWND method.
By doing so my phone's baseband version was changed from the original G950U1UEU1AQH3 to G950USQU1AQDE from SamPWND.
Is there a way to flash the original baseband somehow? I have the original firmware files I downloaded from SamMobile.com
The other baseband version seems to be compatible with my phone since I can make calls and receive messages.
Should I even bother restoring the original baseband firmware?
I flashed the original CSC G950U1UEU1AQH3_G950U1OYM1AQH3_XAA using Comsey Odin (the original Odin was throwing "FAIL! Model dismatch fail" error).
That didn't update the baseband back to stock version though.
I can probably use something like "Partitions backup" app from Google store to restore a partition, but I don't know which partition that is and where to get the original baseband partition image for G950U1UEU1AQH3.
Thank you!

I used the Sampwnd method. The first time I flashed with stock. I then did the samPWND. I didn't have any issues doing it in this order.
I saved the samPWND files and somehow went back in to get them and half somehow was deleted. If there is anyway to send me a link via drive or anything like that it would ve greatly appreciated.
Hello,
I used files from this youtube video to root my S8.
Please check the description for that video for the links.

This will not work on modern bootloaders. Sampwnd is for version one only. See the PartCyborgRom thread for a modern (and mucb simpler) method, no stock necessary
Just flash CP in Odin, that's what I used to do in the BLV1 version so I'm sure it works the same

I think I am good for now, the phone is rooted, working perfectly and I am not planning to update it any time soon, unless somebody finds a way to remove the charging to 80% restriction in this engineering kernel

[Firmware] G950UOYN2BQK5

This is the latest OTA Update for all major carriers. THIS WILL UPDATE YOUR BOOTLOADER SO THERE IS NO GOING BACK! I'm downloading, uploading to my Google Drive and posting this here as reference.
And of course, after flashing this in Odin you can go to https://samsung.firmware.science and chose QK5 to whichever Oreo Beta is latest or you can enjoy having the latest flashable update.
LINK: https://drive.google.com/open?id=1x9-mYPbDKgsa4sS0bMdu9yfmczZywqM_
Uploaded. I already removed the .md5 off the end of the files, just extract and flash away
How do you go about flashing this? Flashing my S5 there was only one file and you loaded that into the AP slot in Odin. With the S8 software it looks like there are 5 separate files. Do you only flash the AP file or all of them? Also, I tried another firmware that was supposed to be Verizon firmwareand had some cricket and metropcs apps installed. Will this be the Verizon firmware that came with the phone from the factory or is it like the other firmware I downloaded and installed from Sammobile? Thanks for any help on this. Trying to get my phone back to how it was when I took it out of the box.

Do you know if this new version of ODIN will read the OLD Firmware files as well as the new ones with the new compression? I know the OP says it will read the new files - but I didn't know if we needed to have two different versions of ODIN if we had phones running older firmware and other phones on new Oreo firmware. ??

Yes, you can use this Odin to flash older firmwares, too. This update just adds support for flashing compressed binaries.

will it work with sm g950F
I flashed Oreo CRB7 final build from Germany and everything is great. But notifications for viber doesnt work as supposed. When i snooze them for only 15 minutes they never appear again and even after 2 hours when i open viber app i have new messages for which i didnt get notification neither sound and stays like that. But when i restart phone everything becomes normal untill i snooze some notification again. I did clean install, clear cash twice and factory reset the phone before Oreo.
Followed the instructions from this site step by step (it was flashing with extracting .lz4 extensions). Help?

Maybe ill try to clean flash it with new odin i have all backups on cloud. Also i get few wifi disconnections from time to time, on my other devices is working great.
For the snooze option-should i have UNDO button in the notification bar when i snooze some apps? Because i have none and i saw it is part of oreo snooze options.
@kernel.killer; hey man, I'm on 8.0 CRAP with custom kernel and other staff I don´t want to lose. If I flashed CRB7 with CSC_Home, will I keep TWRP, root and my custom kernel with my data? or just will I keep my data? Thanks.

Conf00sed n00b needs to restore his 950u to fac

hello, not exactly a n00b, but definitely with this phone.
Long story short, tried to root with Odin using apparently depreciated instructions. Odin halted after wiping my NAND, leaving me with a softbricked phone.
I need help restoring the phone to factory. I have expierienced fail auth and sha256 errors trying do restore.
Which of the dozens of flavors of odin , and which FW do I need to get this back to work? I forgot to mention the carrier is AT&T. So my boot loader is locked.
TY
use prince comsy odin
https://www.sammobile.com/firmwares/galaxy-s8/SM-G950U1/ATT/
Clarification
Is U1 FW the same as for SM-G950U? Just want to clarify before I attempt to flash again. and ty for your reply
Restore worked beautifully, however cosmey errored out and I had to use the PatcheD version of odin to complete. Can someone point me to a guide for rooting the U1 oreo pls?

U 1 can be flashed but you just want the regular U firmware.
Make sure it is the correct bootloader version as what the device is on now or higher. As downgrading is not possible and also throws a fail auth error.
Also use regular Odin 3.13.1 for stock firmwares. Not comsey,that is for modded firmware and such

Yea here's the kicker. Oreo can't be rooted and u1 isn't rooted only rooted is part cyborg rom. Which is U Firmware Also if your bootloader is to high. 3 or higher no downgrade no root
I think we have had quite a mix up or misunderstanding here...The link in #2 points to ATT SM-G950U1 FW. I looked all over the sammobile site and was not able to find any ATT FW for the 950U, only the U1. Also, I was told in #2 to use prince cosmey so I tried. I ran cosmey as admin loaded the 4 Files, left the options on default, and it errored out. So I tried standard odin with default options, it errored out as well. Finally, I used the PatcheD odin 3b and it worked flawlessly. My only question now, can someone link me to a working root method for the 950U/U1
for the snapdragon version of the s8 by at&t? I have tried several, but odin and/or the device always throws an error. I am on the verge of giving up. TY very much for all your help up to this point, I could not have gotten my phone back to working order without your help.
