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.

Cool, which version? 892u?
Were you able to root the stock rom?
Can you just boot TWRP from fastboot/adb?

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

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

Hi everyone, it looks like no development is still being done for this device.
Many download links on this thread don't seem to work.
I was wondering, is there any way I can root my phone? I'm on bootloader 4.
Thanks.

I was going through my logs in recovery mode and part of the log said this build is only for debugging the kernel. If you are seeing this contact your vendor. Not suitable for distribution (something to this effect) what's up with that? would be more specific but I was more concerned about making the thing work atm
Sm-g892u t-moble with v7 bootloader
Could this firmware be put to some advantage? I know a few things but understand enough to admit I am in uncharted waters. Any help or insite would be appreciated

Anyone see this post?

I am eagerly hoping for a root solution for the SM-G892U with firmware version 7.

Maybe colistovo has a breakthrough version?

The guys who where doing it are long gone. More than likely no. It was patched on other s8s. Had to be through edl or syndicate method but no one is activily working on it that I know of

    A Rooted Custom Rom

    For SM-G892A/U on V1 and V2 Bootloaders

    FAQ
    What is my Bootloader Revision?
    Your bootloader revision is part of the baseband build number of the firmware you are currently running. For example, let's consider this firmware version: G892ASQS2BQL1
    Start from the right and count 5 characters back. See that 2? That is the bootloader revision for the firmware that came with this rom. All Samsung firmware follow this formula for all devices.

    Using this formula, What is the bootloader version for G892UEU4GHK1?


    Answer: Bootloader revision is 4



    Updates
    Please see below for a a new update to both the V1 and V2 releases.
    It is a new BL "part 2" tarball that contains a fix for the issues reported by
    many of you with the finger print and other various sensors. It has replaced
    the original firmware Part2 link in the following post .



    Featured Modifications

    Deodexed
    Deodexed for all devices.
    I found a way that works!
    It should continue working as long
    as we care about nougat

    Xposed Preinstalled
    Forget that extra flash, PCR now comes out of the flasher with xposed pre-installed.
    NOTE: Xposed Installer may crash on first boot. It will not crash after setup finishes and you reboot

    New Custom Boot Animation
    Another great one from @rayan-refoua himself.
    This one is my favorite so far.

    JamesDSP
    I added another DSP style audio mod. JamesDSP is similar to V4A in how it operates and what features it has, but it has some really awesome features that have gotten me using it for a while. Specifically it has a better convolver (IRS processing) implementation, and its bass boost is WAY better than v4a. However you can use both at the same time to get the best of both worlds.

    ITYBP Modded YouTube
    A last minute addition, this is a really nice youtube mod brought to you by XXXXXX ADD SOURCE XXXXX. It features some cool features like native adblocking (no more xposed module), override your max youtube resolution (so you can watch 4k videos on your phone), and, not as important to us, spoofing different device types to get true hdr videos. I have been using it for a while and really like it. A big thanks to them for letting me include it with PCR

    Improved Debloating
    I did a lot more digging this round, and was able to add back a few things that I had taken out without loading the system more. This rom feels snappier than any before it. As usual, if you find something missing that you want back, pull it from the stock rom and install it in /system.

    Improved Battery Life
    Thanks to some fine battery sleuthing work by @TheMadScientist, this release comes with a nice big bump in efficiency. With just some very minor tuning using amplify and a service disabler, I can get around 1%/h drain.

    Performance Improvements
    That increased battery life does not come at the cost of performance. In fact performance is better too. Part of that is due to a large batch of personally tested build.prop tweaks make the ui a lot more responsive. Part of that is the data optimisation scripts that now run at boot to make sure things are cleaned up and in tip top shape. You wont notice those, but they are there doing their thing.


    Other Features
    - Pre-Rooted with SuperSU installed
    - CSC OYN pre-installed. Tested working on several carriers
    - RCS and VoLTE icons removed from status bar.
    - High quality audio mods, including
    - Viper Audio (V4A)
    - Dolby Atmos from the Axon 7
    - Pandora hifi audio framework
    - Native Google Dialer & Contacts support, including local search, spam call blocking
    - Oreo 8..1 Emoji Icon Set
    - Custom Lockscreen Clock font
    - Stock system display fonts replaced with Apple's original San Francisco Font



    Special Thanks
    - @ahiron and @Zackptg5 for the killer sounds from V4A and Dolby Atmos Mods!
    - The Aiur crew for Pandora (now a legacy mod but works great on the s8)
    - @syndre for the Google Dialer and Contacts framework mod
    - @rayan-refoua for the beautiful Tech Lines Custom boot and shutdown animations!
    - Last but not least, my new friend @laura almeida, along with @Razerman amd @ZaneZam for letting me include the iYTBP - injected YouTube Background Playback Mod
    - everyone who tested


    Warnings/Disclaimers/Known Issues
    - 80% Battery life like every other rooted US snapdragon device
    - Flashing on a USB 3.0 port will likely cause corruption in your flash that can cause kernel panics, loss of root, and occasionally very strange other errors. If you get something like this, its not the rom its a hardware conflict that can only show up with larger images like are used in SamFail flashing. See the section below on Kernel Panics for more.
    - If there is an app or apk from the stock rom that you wish you had installed, the best solution is to extract it from your stock rom image and copy it to the same place in /system using a root file manager. If a large number of people want something back, I will include it in the next version, but by now I think we have covered all those possibilities and now the list will only get shorter. No I will not put Bixby back ;)



    SamFail Rooting Process
    and Rom Installation


    WARNING: THE FOLLOWING WILL ERASE YOUR WHOLE PHONE
    If you have a SDCard, remove it from your device. Occasional firmware incidents have wiped SDCards in the past. Better safe than sorry.

    Prepare the Following:
    - complete stock rom at your bootloader rev in case things dont work
    - Everything backed up (see above)
    - Both Prince Comsy Odin, and Regular Odin for flashing stock
    - A USB 2.0 Port. If you attempt to flash with a USB 3.0 port it may work, but if you get kernel panics, or unexpected bad behavior and/or crashes your usb3 is absolutely to blame. some people get lucky and suceed after a few tries, YMMV. If you can not acquire a machine with a usb2.0 port, get a usb2.0 hub and run your phone into that & that into your machine. Reports are that has made things work for some, but we get few reports back.
    [/size]

    Steps to Root

    1) Download and unzip AP Part 1 and BL Part 2 zip files.

    2) Download and unzip Prince Comsey Odin and start it up

    3) Reboot device into Download mode, connect to your pc

    4) Open Comsy Odin and add ONLY the AP Part1.tar.md5 file. Select the following options only:
    - "Auto-Reboot"
    - "F-Reset Time"
    - "Nand Erase All"

    NOTE: Odin will freeze while checking the AP tar.md5 hash.
    Be patient, it will come back.

    5) Click "Start" and wait for the system.img.ext4 file to flash fully to your device. This will take a while too.

    ATTENTION:
    When the flash finishes, this is when the SamFail magic happens. Instead of saying "Failed (Auth)" like it should, the device will crash into upload mode with "Unknow Error".

    If your device does not do this, and just says "Failed (Auth)" or something similar and stays in download mode, you need to start again from the beginning, but using a different set of ub ports as you have suffered from the usb3 corruption.

    When you see the upload mode page, use the 3 button reboot to go back to download mode.

    WARNING: When you reboot from upload mode, your phone will show an error instead of download mode.

    When you reboot back into download mode, your screen will say that you had a failed update and you need to do emergency repair or take your device to a service center.
    Rest assured, your phone is actually in download mode, and Odin will have recognized it and said "Added!" along with the com port lighting up underneath the progress bar.
    It is safe to continue

    6) Close and re-open Comsy Odin or hit the reset button, and add BL_PartCyborgRom-BootLoopEdition-<version>.tar.md5 to the BL section.

    7) Leave the default checkboxes for "F Reset Time" and "Auto Reboot" checked. Click "Start" and flash the BL (part 2) to your device.

    8) Wait for the flash to finish . It won't take very long at all all the files are small.

    9) When it has finished, Odin will say PASS and your device will reboot into recovery.

    Warning: Failure to follow this step could lead to a corrupted instance with no cell coverrage

    10) When in recovery issue a factory reset. This ensures that your device has a userdata partition that is valid, and that the csc is processed correctly. Failure to do the reset could cause issues with either.

    All done!

    Pledged a donation for the root bounty? Send it here. Thank you!


    IF YOU GET A BOOT LOOP:
    If you get a boot loop or your device hangs at boot, try the following:

    1) Reboot to recovery and factory reset again.
    To get to recovery hold power+vol-down until screen goes black, then wait till upload mode (press power key for 7+ secs) comes up. Then press vol-down+power again and hold it till it reboots and as SOON as the screen goes black switch to holding vol-up+power+bixby. Hold it for 5-7sec then let go and you will wind up in recovery mode.

    Kernel Panic, Invalid Argument

    Start the process over
    Go back to the beginning and do everything again. If it fails in a new way this time, you may have hardware caused corruption, or maybe you missed a step. Change hardware, and keep trying.

    I need someone with flashing experience to test a rootable v3 version of this rom.

    Is there anyone who fits the description and has a v3 device that is interested?



    Please don't volunteer if you have never done this kind of thing before, if you are unfamiliar with odin, if or you have trouble understanding the instructions in the op. It will just increase the possibility of v3 being falsely confirmed as patched when it actually isnt. If/when its confirmed to work everyone will have full access
