Unrooting / Stock Reflash Using ODIN

Download Samsung Driver here

Download Odin: XDA Thread Here

Download Stock Firmware: (You will need to know your model number)

XDA Download Thread (Has At&t firmware listed, other two links does not.)
SamMobile Firmware Downloads
GS6Root.HighOnAndroid Downloads

From WonderHowTo
Step 1: Boot Your Phone into Download Mode
To begin, you'll need to boot your phone into Download Mode so that Odin can access your system partitions. From a powered-off state, press and hold the volume down, home, and power buttons simultaneously. At this point, you'll see a warning message—but like it says, just press the volume up button to enter Download Mode. At this point, just connect your phone to your PC with a USB data cable, then the rest of the work will be done on the Windows side of things.

Step 2: Install the Samsung USB Drivers on Your Computer
From your Windows computer, start by downloading the Samsung USB Drivers. Once the file is saved to your PC, simply launch it, then follow the prompts for installation.

Step 3: Install Odin on Your Computer
Next, you'll need to download Odin itself. The latest version can be found at this link, and all you need to do here is extract the contents of the ZIP into a folder you can access easily.

Step 4: Download Your Stock Firmware File
Finally, you'll need to grab a copy of the stock firmware for your particular variant of the Galaxy S6. Start by heading to one of the links above to download your firmware. If you're unsure of your exact model number, refer to the user manual that came with your device, or look under the "About device" menu in Settings.

Step 5: Open Up Odin on Your Computer
At this point, you're ready to flash the stock firmware on your Galaxy S6. To begin, right-click the Odin3-v3.10.6.exe file, then choose "Run as administrator."

Step 6: Select Your Firmware File
From here, leave all of the options selected exactly as they are, then click the "AP" button near the center of the window. At this point, a file browser menu will pop up, so use this to select the firmware file that you extracted from the ZIP in Step 4.

Step 7: Flash the Factory Firmware
After selecting the firmware file, keep an eye out on the "Log" tab near the bottom-left corner of Odin. When it says "Leave CS," you're ready to flash the firmware. Click the "Start" button at the bottom of the screen to begin.

At this point, Odin will get to work on flashing the stock firmware. The process will take around 10 minutes, but when it's done, the box in the top-left corner of Odin will read "Pass," and your phone should automatically reboot. If it doesn't reboot, press and hold the volume down and power buttons on your phone to manually restart the device. At this point, you can disconnect your phone from your PC.

This first boot will take a lot longer than it normally does, even as much as 10 minutes. But when you get back up, your phone will be 100% stock from a software standpoint—but keep in mind that nothing can reset a tripped KNOX counter, so you may still see a "Custom" status if that's the case. If you experience any minor glitches after restoring the stock firmware, simply reboot into recovery mode and perform a factory reset.

if you can get it back into download mode, then look for the knox code and if it changes from 0 to 1 or says 0x10000 instead od 0x0000 or anything changes besides 0 (0x000) your phone has identified that the system was faulted by the flash and therefore your warranty is now void because the knox security system has changed from the original setting. If it says custom most likely it has detected as well that the system was flipped but because you said it still says samsung official they may let it slide. But im not sure what that means i believe is that the phone is an official samsung and that the flash was an official samsung code but it wasnt the original code on the phone. Sometimes a flash on the phone will change the imei so that could mean why the phone is now custom, More than likely though the repair person will have to flash your system anyway and if that doesnt work then your motherboard isnt being read by NAND and you probably need a replacement, i have been up solving mine and calling eveyr technincian store, repair person, and customer service since my phone did what yours did about 3am this morning. Ive got no sleep had about 3break downs and sadly i think it needs to just be professionally checked. My NAND keeps getting a write fail and nothing is passing over to my phone. i can still get into the recovery mode to perform factory resets and cache wipes but it says dm-veridity verification failed and even after multiple factory resets and cache wipes and accidentally hitting the adb button it has led me no where but a continous boot. My phone is only 12days old. Samsung will cover it because i didnt knock my warranty or show evident of any faulting with the OS. The phone had done a update to a new firmware and once that finished i did a factory reset from the phone settings and when i went back to wipe the cache the phone shut down and since then hasnt been able to go past the logo SAMSUNG GALAXY s6 screen powered by android. So as upset and dissastisfied as i am with the phone, i definately appreciate all the youtube videos, forums, repair technicians, and customer service advice i got today. I have definately learned more than i needed to know lol and downloaded about every type of odin available and both firmwares for the lollipop 5.1.1. for samsung galaxy and the original 5.02 the 5.02 got the farthest in download until it shut down because of the written fail and then again because of COM port, but the other one didnt even get past system configuration so i guess something needs to be looked at immediately. If you know anything please do respond back to this message before i send mine off thanks a bunch lovelies

my phone is a samgun galaxy s6 with model SM-G290P (sprint), i was originally on android 5.02 i guess but i got the phone activated in stores so when it was given to me from the moment i had it i was on 5.1.1. , i also noticed that my phone goes through odin mode easily but wont connect to the computer i have installed the smart switch, uninstalled after it failed to work with kies, i have installed the mobile drive individually and it picked it up on odin but wont pick it up on smart switch. I do know that if i can locate my s/n number then i can just plug it into smart switch to do the factory flash but i cant locate the s/n number being my phone is turned off. i tried the DEC,HEX AKA IMEI, ICC ID, RS UNDER THE BARCODE, AND none of these codes seem to be a valid s/n number. if someone could assist me with that i would be TREMENDOUSLY GREATFULLLLL!!! ALSO BEFORE i could just click my power button once and the phone would come on now i have to slightly hold it a few second for it to even show the logo.i have also noticed that if i charge my phone the phone loops otherwise if i go to download and cancel and then power on the device manually then it shows the logo once and then shuts off. so hurt you guys!

ALSO WHEN MY PHONE IS OFF I CAN SEE THE BATTERY IS CHARGING RIGHT NOW IT IS AT 82%, sorry for the caps i was typing and reading the phone. On the recovery mode update using ADB is disabled apparently and so is the option to update using external storage the apply update from cache is deprecated too and also when i started having a problem when i hit the power button home button and the volume up it showed the little android man died now it shows he is ok and up right like normal but the dm-verity verification failed still , I AM ABLE TO SEE EVERY LOG IVE RECREATED IN RECOVERY UP UNTILT EH VERY FIRST CACEH WIPE I DID THE DAY AFTER I RECIEVED THE PHONE. IS THERE A WAY I CAN TAKE THE IMAGE OR INFO FROM THIS TO REFLASH THE PHONE MAYBE?!!?!?

Ok a quick look, it seems you have downloaded 5.0.2 firmware and trying to flash it to a phone that was already updated 5.1.1 which you can not do. You can not down grade after updating. This is why it keeps failing. Try downloading this Firmware and flashing it with Odin. The link will be the 5.1.1 firmware that should flash to your phone with no problem.

When you get into odin mode press home instead of vol+!
There you will see 2 barcodes, under one of them is your serial nr., that you can use with kies recovery rescue.
Be advised device name is case sensitive.

SM-G920T bootloop/bricked. Only have ODIN mode

Was streaming some music when my phone decided to shut down. I thought it was out of battery since it was low so I plugged into the charger. Now it only boots up to the Samsung logo and nothing else. I cannot access recovery, only Odin (download mode). I set it to download mode and tried the emergency recovery on Smart Switcher. No luck still boot loop. I then tried to flash the stock firmware via Odin 3.10.7 and still no luck. I was on G920TUVU3DOI1. I bought the phone pre owned on Swappa and the previous owner assured me it was not rooted or tampered with in any way. My system status reads Custom though. Knox is not tripped. Would attempting to flash via Odin have given me the custom status? Samsung store here won't touch the phone since it says Custom for system status. Since I wasn't planning on rooting this phone until after the warranty period I did not do any of the options in developer mode. So now I have FRP lock to contend with. It blocks me from installing a custom recovery. Does any one have any other suggestions I can try?

Thanks in advance!

Were you rooted on 5.0.2 and trying to update to 5.1.1 by chance?

If you can still boot the phone, , I think all you need to do is turn off reactivation lock via Samsung account.

Thanks for maintaining this thread. I recently rooted and found there was so little information out there about rooting an S6 (compared to when I rooted by S3 years ago). I also found that, once I found the right information, it was incredibly easy. The difficult things were:

1. Doing a nandroid backup before flashing a custom ROM. Since there's no external SD slot, I ended up buying a USB OTG cable and plugging in a flash drive. It also took a while to figure out that TWRP can't read NTFS, so I had to re-format the flash drive with FAT32.

2. There aren't a lot of ROMs available for the S6. I ended up starting with XstroLite, before realizing that it doesn't support T-Mobile wi-fi calling. I then switch to Atrium, which has been working great, except that the developer has since stopped development and moved on to other phones.

3. Using Titanium Backup to backup my apps (important: WITHOUT data) saved so much time. I used the feature to create a .zip file, which I could then flash in recovery (after booting up for the first time and installing Titanium) to save time. Backing up the settings for some other apps, like Nova Launcher, also saved a ton of time. SMS Backup & Restore was also easy to use (but if you're using Textra, you'll need to reinstall it after you restore).

4. Even after installing a slimmed-down ROM, you may still need to use Titanium to freeze/uninstall some apps that can't be uninstalled through the launcher (such as certain Google and Samsung apps).

5. BetterBatteryStats, WakelockDetector and especially Greenify have been amazing. Even if you only root without installing a custom ROM, these apps will greatly improve your battery life. I could never really get Greenify working to its full potential before rooting.

Before root and custom ROM, I would come home from work with 20-25% battery left. Now, I come home with 60-70%. My resting battery drain (screen off) used to be at least 3%/hour, and now I'd estimate it's 1% or less. The phone has got significantly faster and more responsive.

I just hope there continues to be some ROM development for this phone. It seems like once they announced the Nexus 6P, everyone moved on pretty quickly.

Root failed, could not boot. Flashing stock firmware failed and still stuck in bootloop, is there a way that everything to be in working condition. I'll wipe the device if I need to.
