Yeah, the failure I had flashing ap the first time was that Odin froze with the wrong error code and my phone froze on the download mode screen, worked the 2nd time around after I flashed the bl, thought that might help someone if they had a similar issue.

Repeated AP -> BL sequence several times with both "failed", every time, with Failed (auth). My device is SM-G892A with V2 bootloader. Any ideas? I tried same operation on 4 PCs with 4 different USB cables. Cable can't be an issue, it's a digital communication, not analog and it either works or doesn't work. All my cables work with other phones/devices no problems. They also worked with the S8 when in download mode.

Can you please share where I can find stock V2 firmware to return back to stock using Odin? I searched everywhere I could with no results... I failed to get root, both AP and BL flashing ends with Fail! (auth) no matter which PC or USB cacle I use. My device is in endless boot loop now unless I'm in Download mode. Thanks in advance...

For V2 bootloader the BL file is supposed to be PartCyborgRom.G892A-2ARA1.Part2.zip, but the file on the server is PartCyborgRom.G892A-ARA1.Part2.zip. Is the file correct? When flashing the file on V2 bootloader device it gave me FAIL! (Auth) error every time I tried it. I'm just wondering if it's my luck with the PC/USB port/cable combination or the BL file is for V1 bootloader... Thanks.

I can't flash BL "PART2" for the V2 bootloader, it fails every time (please see the attached picture). I suspect the BL part is not for the V2 bootloader because of the name mismatch in the link and the file in the server itself.

I succeeded flashing AP V2 (part 1) when flashing over the COMBINATION firmware, on the very first try. Before I tried USB2 ports on 4 different PCs with a bunch of different USB cables countless times, with zero success.

Please help with the BL part (part 2)

When BL/part 2 fails the phone says "SECURE CHECK FAIL :apnhlos"

Any help with BL part not flashing successfully on V2 bootloader? Frankly I bought the S8 Active only after seeing this root guide. Without the root the phone is useless. Carrier, Google, Facebook and many others can do with my phone whatever they want, while I can't do anything about it. I would be happy to donate $50 if I can get my phone rooted. Any help would be much appreciated...

Guys, anyone encountered problems while flashing BL (part 2) on SM-G892A with V2 bootloader? I tried everything I can think of while strictly following the instructions, with no success, flashing fails. Anyone succeeded getting root on V2 bootloader on G892A? Phone without root is as good as bricked for me.

All gestures stopped working

So I imagine this isn't unique to the rooted S8 Active, but I've searched around for about an hour and haven't found any other instances of this.

It's happened twice now where out of the blue (both times while picking up a phone call just as I'm missing it) the security screen stops working. I put in my PIN correctly, hit okay, the screen hangs, then fades to black as if I hit the lock button. Open the screen again, swipe for the PIN, enter PIN, same. Totally locked out. Used Find My Device to remove PIN login and it unlocks phone, and swipe unlocks, but when I reset the phone it just pulls up a black screen. No option to unlock, but I can see notifications, so I have to pull down notifications and trick my way into the phone, and then it works as normal. For now at least.

When this happened last time, I got back in with Find My Device, and just added the PIN again, and it worked as normal til now. Now, even when I unlock it then try to add the PIN (or any other security measure), it does the same thing where the credential simply doesn't work, even when entered correctly.

I've tried searching for any info on this but haven't found any cases of it. Thoughts?

I Unlocked bootloader for sprint G892U

I am getting a new phone tomorrow so i didnt mind tinkering with my s8 active, I was able to flash a combination file and unlock the bootloader, then relash the stock rom, while on the stock rom i could not see if it was still unlocked or not so i flashed the combination file again and it was still unlocked. i am not an advanced user, just a little tech savy. i tried several twrp builds for s8 and none worked, and i am not experienced enough to compile it myself. i belive root is possible again on multiple carriers using this meathod if we had a twrd built for this device. warning i did trip my knox fuse.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] robnitro:
Cool, which version? 892u?

Were you able to root the stock rom?

Can you just boot TWRP from fastboot/adb?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] Thr45h:
Yes the 892u V6 I did not try fastboot/adb but I dont think any of the twrp builds work with this phone, I just got my new phone so my s8 active I can toy around with and not worry about bricking if anyone has any ideas I'm glad to help. But to answer your question no I did not get root but the bootloader is unlocked which means if I can find a recovery that works I can achieve root
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] TheMadScientist:
You did not trip Knox. You did not unlock the bootloader. I assure you. The oem unlock in combo only shuts off frp. It did not unlock the bootloader

You cannot unlock the bootloader. Just cause you where in factory binary and clicked the oem unlock does not mean you unlocked it. It don't work. These devices are permanently locked. There is no twrp there is no root after rev 3 or 4

Hey folks, sorry I havent gotten back to any of you. I just posted a new version of the Part 2 "BL" tar.md5 in the Downloads post below the op. It should address all of these issues and more. Please let me know if it does not and I will investigate immediately.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] G0bl1n:
Actually almost everything works except for some minor problems. You have to flash the Combination firmware before following the guide (otherwise flashing AP wouldn't work for me). After flashing the corresponding Combination firmware in my case flashing AP (part 1) and BL (part 2) from the post #86 (not from the post #2, the main post has incorrect BL part for V2 bootloader) the phone boots OK if you follow the guide precisely. The only small problem I'm getting is the error message "the process com.android.phone has stopped". I did followed the guide exactly and did the factory reset a couple of times immediately after flashing BL. I also repeated the whole flashing process 3 times but at the end "com.android.phone" error message is there every time.

[MENTION=8360749]partcyborg[/MENTION]. Thanks for the great work!

I'm stuck in a boot loop, and the reboot steps in the OP don't work for me... any other thoughts?
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] G0bl1n:
You can try to restore stock firmware and try this again. I restored my (AT&T, V2 bootloader) like 5 times by now. Just be careful to restore the same level of bootloader, otherwise if you are on V1 and update to V2 there is no way back.

To get out of the reboot loop hold together power + volume down until your phone shuts off. After that hold power + bixby + volume down to get to the Download mode. I experienced the bootloop several times but was able to get to Download mode with the described sequence.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] SomeoneE1se:

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] partcyborg:
All 3 of you need to try again from the beginning and follow the directions carefully in the OP. Make particular note of the part about not flashing using usb3.0 ports. Flashing from a usb 3.0 port that the s8 seems to disagree with will cause corruption in the data written that exactly looks like what you are experiencing. If you don't know if your ports are usb3.0 or not, try them. If they don't work in any way involving failing to boot, mentions of "Invalid Argument", or (although this is more rare) more subtle things like "major binaries crashlooping", or "mysteriously does not have root" (this one actually happened to someone due to usb3!), the

Once again, read and follow all directions. Unfortunately I cant make a rom that fixes low level odin issues (I totally would if I could), which is why I put those warnings in there, to save everyone a ton of headache and phone downtime due to things that myself and the other amazing hardworking volunteers in this thread and my other ones have already figured out how to solve.
[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] partcyborg:
If you are getting Fail(auth), you are probably on revision 2 bootloader and need to flash that one.

Sounds good, thank you very much I will try on another computer, I've tried both 2.0 ports on this laptop I'll try the desktop.

oh dang, i thought my desktop had 2 usb2.0 ports but apparently they are 3.0, I'm found a 2.0 usb extender that I'm going to try using. First I'm going to reflash stock, then do a factory data reset, then try following the guide again.

[MENTION=8360749]partcyborg[/MENTION]. First of all, big THANKS for the advice and for doing all this, I personally really appreciate your work and efforts, this all is amazing!!! I'm keeping my fingers crossed and visiting this forum like every hour hoping to see a good news. But I suspect there are other variables that may influence the success of the flashing or how the root ROM is accepted by my phone. As an electrical engineer (I'm a guy who develops hardware for a living) I'm sure my USB2 port works fine, it never fails flashing stock firmware or Combination firmware using Odin. I got root on all my phones using the same USB2 port. I did try the same operation on other 4 computers with USB2 ports just in case but the behavior is repeatable on all of them. May be a dependency on a ROM version we are coming from? I was able to flash your ROM only over Combination firmware (and I have only FA70_G892AUCU2ARA1 Combination version). Could it be the difference in CP/CSC version and the root ROM since my understanding is we are not flashing those? My stock rom version is NRD90M.G892AUCS2ARA1 when looking at the "Build Number, please see attached screenshot. Thanks again for your efforts!

Okay so I've made some progress.. I first flashed a stock rom and completed the initial setup to get passed the welcome screen, then I flashed the BL linked in this post and booted the device back up. After that I followed pretty much everything in the guide except for checking the erase NAND option. When I rebooted the device I was able to use the apps including xposed and superuser, but I still kept getting the process android.system.phone error popup and had no cell service.

[Samsung Galaxy S8 ROMs, Kernels, Recoveries, & Oth] zackr123:
NRD90M, 2ARA1. I basically did a dirty flash, do the BL first and boot into stock AP. Set up phone so that the welcome screen doesn't come up again. Then flash the AP from the OP, and don't do a factory data reset or reflash the BL. From there you can use the phone and use a root uninstaller to get rid of the apps that are causing the com.android.phone issue.
