SM-G900A (ATT) Wont unroot

I have tried everything I can find on the internet. Various Odin versions, and a bunch of stock roms from sammobile and other websites. I have been trying to follow everything to the dot, but I keep getting the same error: FAIL (AUTH) seconds after I press start. I have turned on USB debugging on my phone and I honestly don't know what do to. I just want to unroot and be done with this already. Please, someone help!

have you tried supersu to unroot? lol

No I haven't and I haven't even heard of that program yet, let me try and see. I'll post back the results.

Everything ran smoothly but I still have the "Custom" with the unlocked lock icon on my phone's start up. Also, my phone still can't update its software. It boots like it's going to but the installation is stalled at 25% until it just reboots and gives me a message that the update was interrupted. Please help!

what rom are you on? maybe the rom your on removed the update apks from the rom? the custom lock will be there until you manage to flash a full stock odin tar successfuly..
theres no reason the odin tar isnt unrooting the device if youre using the full odin tar.. this should put original rom/kernel/modem and wipe device completely

See, I think that's the problem too. I had this phone rooted once before and I intalled a rom (that i forgot the name of) and then i installed the supposedly official ROM for SM-G900A and I think that's where it got messed up. What should I do now?

Need help upgrading bootloader and modem

I've gotten no help at all with this. Very unlike this forum. My phone is a kltevew, which is straight talks version of a g900v. I need help, there are lots of great looking Roms that require you to have mm firmware I'd like to try!

Not sure why I'm getting g no responses on this. Surely someone must know something... The only response I got was not only not helpful but jerky and obnoxious. Doesn't anyone know how to upgrade the firmware on my phone? (And no, google has no answers for me on this.. I look everyday)

Download it with samfirm http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647 (Model= SM-G900V Region= VZW) or from sammobile http://www.sammobile.com/firmwares/database/SM-G900V/ , do you know how to flash firmware with odin?

I do. Thanks so much for responding. Every time I try with Odin, a few different releases, it always gives me the error message fail. Can it be done with flashfire?

What stands in the log of odin when the flash completes?

Ill have to do it again to see... Be back in a bit!

I think it says FAIL! modem but I'll have to run it again... Brb

Last night I used flash fire to install firmware. That didn't get past the red Verizon logo, so I put twrp on it with Odin. Twrp showed it as dpd1, but it just wouldn't boot. So I wiped it once and flashed a ROM that requires mm firmware. Same thing, justbootloop. So I put stock back on it, then mokee 6.0.1. which works, I'm just not on mm firmware and all the great new roms are still unavailable to me.

Have you enabled the option to flash bootloader on flashfire setting?

What? No, I haven't... but do do right now. Thanks for the tip! Actually, where would I find it?

So would I do it in this order? Flash the dpd1 bootloader, then modem, them rom, then jrkruse patch? All in flash fire?

It's in setting of flashfire...but only do it if odin doesn't work because do it from flashfire is more riskiy...
1)do a backup
2)check the bootloader flash option
3)install the firmware with all the wipe except internal storage(it mean that flashfire delete /data excluding /data/media/0 (sdcard) but include it in your backup copy because you never know )
4)wait till reboot skip setup wizard "spamming" the next button then install the rom with flashfire or twrp
On the flashfire site i found this:
Flash bootloaders
"This setting controls if FlashFire will attempt to flash bootloader partitions. By default, bootloader partitions are only read and never written. Even when enabled, flashing bootloader partitions may not succeed - many devices have protections in place against the bootloaders being overwritten.
Please note that flashing bootloaders is extremely dangerous. Any bug, error, or failure may result in an unrecoverable hard-brick. Do not use this feature unless you know exactly what you are doing.
Due to the danger of this feature, it is automatically turned off every time FlashFire starts. You have to manually re-enable it every time you want to use it.
If you must flash bootloaders, it is advised to use a bootloader-based flashing tool such as fastboot or ODIN to do it, as these are the safest methods. OTAs may also update bootloaders, and though slightly less safe than fastboot/ODIN, it is still much safer than having FlashFire flash bootloader partitions directly."
So i suggest to try to flash the firmware directly from odin first

No dice... still doesn't boot up past the red Verizon logo

did you install the firmware in the "AP" box on odin? (after you factory reset your phone)

I did. At this point guess I'm lucky I haven't bricked my phone. Ive tried every possible combination, nothing works!

Redownload the firmware extract it again,factory reset your phone,and try to install the firmware,maybe it's a bad download

Should I be flashing a kernel too? Will it even start/boot without the right kernel?

find out if you phone is refurbished. to install stock ROM you would need the main board and boot to be the same model.
if it's not, then you just need to install bootloader/modem without full ROM. look around in xda for bootloader/modem.

Its not necessary to flash stock, simply reflashing the engboot will suffice, and does not wipe the device.

First of all you wanted to Flash SuperSu.... Did you enable Android Debugging.... Then check OEM Unlock?
If not you messed up there...
Next You need use Odin to flash CF-Root. You are now running a patched Kernel and SuperSU
Use TWRP app to install twrp for your device.

i have the same exact problem, been trying to flash stock firmware but cant get it to work. help please!!!! which firmware? can i get a link please!!!!!!!!!!

Hello, having same issue. Didn't realize you can only make backups with flashfire, not actually flash them back with the program too...
I have the original files I installed with Odin, are one of these the engineering boot file? (BL, AP, CP, CSC?)
Or are you talking about something else...? Thanks!

You flash the engboot file you used to root the device, the one you placed in AP and is around 20 mb in size (not the actual firmware) .

[Q] Cant flash Stock rom anymore

Hello everybody,
I got a Samsung Galaxy S7 Edge (SM-G935F) DBT version and flashed a Custom ROM (Firmware? idk the difference).
I did that like this: youtube.com/watch?v=_1ofpLHMVvA
Unfortunately there were a few problems there, like the camera is awful now (Bad quality and other camera apps didnt made it better).
So now I want back my Stock ROM. (Yes, Unfortunately I didnt made a Backup)
But I cant get it back, neither with TWRP or with Odin.
At Odin its stops at system.img and fails than and at TWRP I guess I used the wrong Rom because is said Zip file is corrupt!.
The following Stock ROM did I use for Odin and TWRP: updato.com/firmware-archive-select-model?record=2A12F0CE03CD11E7963AFA163EE8F90B
At Odin I unziped it and added it the right way: (BL, AL, CP and CSC).
At TWRP I didnt unziped it and used it like it is.
I hope you can help me there.
I have already made the following:
Changed USB Port
Changed USB cabel
Used Smart Switch
And yes, I can still install custom roms like LineageOS and Resurrection easily via TWRP.
Greetings, Darkatzu.

It is, because you will need no verity opt encrypt to flash too alongside official stock rom in order to use stock rom if you rooted by system modification method, with oreo 8.0 I think no verity zip is not working, so you need to flash latest nougat for your country/region alongside twrp , no verity zip and super su, you can download latest stock firmware for your region from samfirm application or updato, also download odin version 3.13.1, latest twrp recovery, super su and no verity opt encrypt from here on xda forums, first check and enable oem unlock, flash stock rom and then flash twrp through odin, then boot in twrp recovery and flash no verity and super su zips, to get detailed info on above steps search the forums. AND PLEASE TELL WHATS ASKED IF YOU WANT TO GET HELPED.
!! NOTE : IF YOU ROOTED FIRST TIME BY SYSTEM MODIFICATION METHOD, AND THEN INSTALLED CUSTOM ROM, THEN FLASHING STOCK ROM BACK WILL PUT YOU ON A DM VERITY ERROR. ALWAYS REMEMBER TO ENABLE OEM UNLOCK IN DEVELOPER OPTIONS BEFORE DOING ANYTHING!
HAVING OEM UNLOCK DISABLED AND THEN ROOTING VIA SYSTEM MODIFICATION METHOD, AND THEN FLASHING STOCK ROM WILL PUT YOU IN A HARD BRICK SITUATION WITH BOTH DM VERITY ERROR AND CUSTOM BINARY BLOCKED ERROR !!
As far as I know the above situation has no solution if you get into this mess and only a memory swap on board or some box can fix this. I know many users here on xda are stuck on this situation. Some users said they fixed this by using nand erase all and re partition using pit file options during flashing in odin, but I really doubt enabling these options will solve this if not making problems worse. Anyone is welcomed to correct me if the above situation has any solution. BUT THAT IS WHY SYSTEMLESS ROOT IS THERE TO AVOID ALL THIS...

Maybe you are using an older bootloader ? Can't say for sure whats causing it, the method you used above I think required system modifications, but you are using a march 2017 stock rom, so it looks updato don't has V2 bootloader firmwares for DBT, problems may happen when flashing an older bootloader on a newer one, it could also be your pc or other hardware problem, but in case try again and download samfirm from here : https://forum.xda-developers.com/attachment.php?attachmentid=3803841
Enter DBT as your region and model SM-G935F , it will download the latest stock available, be sure option for auto decrypt, check crc32 and binary nature are ticked.
After that check oem unlock and usb debugging is enabled and follow the steps :
1. Put phone in download mode, use original usb cable, and make sure pc usb port is working correctly. Also phone must be charged above 50%.
2. Download odin 3.13.1 from here https://forum.xda-developers.com/attachment.php?attachmentid=4431597&d=1519662712
Latest twrp available https://eu.dl.twrp.me/hero2lte/twrp-3.2.1-1-hero2lte.img.tar.html
Latest no verity opt encrypt https://build.nethunter.com/android-tools/no-verity-opt-encrypt/no-verity-opt-encrypt-6.0.zip
Latest stable super su https://s3-us-west-2.amazonaws.com/supersu/download/zip/SuperSU-v2.82-201705271822.zip
3. Put phone in download mode, extract the firmware downloaded above from samfirm tool and put the respective files in their boxes, use CSC and NOT HOME_CSC. Make sure no option other than F.reset time is ticked in odin options. Begin the flash procedure. After it is completed, don't reboot and place twrp zip downloaded from above in the AP tab of odin. After it is completed, stay in download mode and hold power+home+vol down to reboot from download mode and immediately switch to vol up button to boot in twrp recovery menu.
4. In twrp recovery menu, you need to swipe for system modifications or tick read only ( if you previously allowed for system modifications then you can do it again it doesn't matter, but if you previously didn't swipe for system modifications then tick read only and download systemless zip from https://forum.xda-developers.com/s7-edge/development/samsung-systemless-devbase-encryption-t3517178 )
I will recommend this as you won't need to flash dm verity.
5. Now, go to wipe> format data in twrp recovery, after its done, flash super su and system less zip through twrp to get system less root if you don't want to get dm verity error hassle when flashing stock roms OR flash super su and no verity opt encrypt if you already have allowed system modifications. After that reboot. It may take sometime.
Also to note if you never allowed system modifications before in twrp, and you don't want to root either, then you can safely flash stock without flashing twrp or going through further steps.
This is what I could best explain according to my limited knowledge, if you still fail to flash stock in odin, then I am not sure it may be your pc or other hardware problem and you may need a repair box, try checking on another pc or some expert user to help. Good Luck.
These steps are only for installing stock rom back on previously rooted S7 edge devices using custom roms and for rooting a stock rom.. and only applies to SM-G935F

Same error.

Sorry I couldn't be much help. Does it always stucks in odin at system.img? Looks like its a hardware problem in your pc/usb ports or phone's usb jack. Try getting your phone checked by a repairer, flashing from another pc or changing usb cable. Also try running odin as an admin or try with an older odin version. Good Luck

And yes, I changed PC 2 and yes tryed other versions of Odin LIKE where AP is named as PDA.

Strange thing if you could flash recovery but not the stock rom, looks like you need to get it checked by a tech. But as a last resort did you tried using pit file and repartition ticked? To get the pit file extract the CSC file and you will find .pit file there, open pit tab in latest odin and select that pit file, then tick repartition box and proceed to flash with all other files selected in their respective boxes. If its still the same then I guess I can be of no more help. Cheers !
!! Warning : Using pit file is never recommended and it could brick your phone permanently if there is any power outage/usb disconnection during flashing with pit, it is used to correct file system partitions if they are changed/corrupted. Its better to outweigh benefits with potential danger. Also a pit file will erase all partitions first, then write flash data from beginning and if you again stuck at system.img when using pit file, you will be left with a permanent brick. So I will recommend to get it checked by a tech if you want stock rom that bad and don't do any risky thing with your pricey phone

Need help unbricking.

Yesterday I tried root my S8 (SM-G950FD) and I made the mistake of not allowing system modifications before flashing because I misinterpreted a guide. I flashed the no-verity zip and Magisk. The phone booted successfully and magisk was installed. Then I went to reboot into recovery to change some TWRP settings IE: Brightness. Then my phone said "Only officially released binaries are allowed to be flashed." That left me unable to boot my phone and also made it unable to boot into recovery. The only thing I can boot my phone into is download mode. I've tried flashing some stock roms that are 7.0 to remove the prenormal lock but they failed. I happened to make a TWRP backup before flashing but I can't use TWRP because of the official binary stuff. I'm wondering if I use the nand erase all option if that will let me flash the 7.0 stock roms then boot into TWRP and restore my backup or if they is way to convert the backup into something that Odin can flash. Does anybody know any confirmed methods to solve my problem?

Then my phone said "Only officially released binaries are allowed to be flashed." That left me unable to boot my phone and also made it unable to boot into recovery. The only thing I can boot my phone into is download mode. I've tried flashing some stock roms that are 7.0 to remove the prenormal lock but they failed. I happened to make a TWRP backup before flashing but I can't use TWRP because of the official binary stuff. I'm wondering if I use the nand erase all option if that will let me flash the 7.0 stock roms then boot into TWRP and restore my backup or if they is way to convert the backup into something that Odin can flash. Does anybody know any confirmed methods to solve my problem?

You will need to flash the same or higher version of Android to fix official binary error. Use default settings in Odin.
You cannot.flash earlier versions of Android if your bootloader is lower than what is on your phone ( 5th number from right of firmware name ). If in doubt flash the latest version.

Then I went to reboot

Ok so in few minutes from now the rom will be finished downloading. When that is done what version of Odin should I use and what files should place in Odin. I know this may seem stupid to ask but I'm not going to let myself make anymore stupid decisions after not installing the rmm bypass.

Quick Update, the rom finished downloading. I wasn't able to flash it. It gave me the error that the Bootloader had: 4 and the binary had 3... I was able to flash cp by itself tho and that set the system status to samsung official but the binary status is still custom. That made it so my phone only booted into a "Update failed screen use smart switch" screen ( I've tried smart switch before it doesn't detect my device). I can still get it back into recovery and flash old cps to get it to turn off without bootlooping into the smart switch screen. I'm wondering if I flash csc to factory reset if that will help at all. Guys what do I do??

Excuse my language but I ****ING DID IT!!! I don't know this worked but I am going to roughly call my process. So flashing the stock rom initially failed. I flashed then CP which for some reason always works and then AP which began but failed. This set the binary text to "Samsung Official", system status was still ****ed as custom. So I restored the cp and ap(?) from the crgb oreo files posted here. Then I flashed cp that passed, then csc which passed and then tried AP. After some time... It passed. The phone rebooted. The official binary bull**** was gone from the bootscreen and the phone booted into recovery. It installed some sys update stuff up to 30$ then erased some things which took awhile. Then the phone booted into initial setup and I now have ACCESS TO MY PHONE AGAIN!!!
For anyone interested in what FW I flashed PM me.
