Boot into fastboot mode and install the latest version of TWRP, which is 2.8.7.0. You can download it from the TWRP official website.
Code:
fastboot flash recovery recovery-file-name.img
Boot into recovery and connect your phone to the PC.
Download any ROM from the forum, transfer it to the phone and flash it. Don`t since we don`t know anything about your previous ROM wipe cache, dalvik, data and system before flashing your chosen ROM.
Since you`re S-On, extract the boot.img file from the ROM zip and flash it manually in fastboot mode
Code:
fastboot flash boot boot.img
Reboot phone and enjoy.

No need to extract anything. S-on doesn't matter for kernel flashing on this phone. So, flash ROM.zip and enjoy

"any ROM" from the forum won't work on his phone. For example, his actual firmware is way to old to run roms based on Sense + Lollipop. With this firmware version (2.24.401.8), he is limited to JellyBean or Kitkat Roms.

Won't hurt but not needed on the M7 (unlike some other HTC phones). The kernel partition isn't secured and is flashed with the rom from twrp.
@zuppiger
If you want the phone back to stock and be able to intall ota updates (or if you want to install a custom lollipop + sense rom), flash this rom using twrp recovery. Select "yes" for stock recovery and stock radio, select "no" to root. then reboot the phone to the OS, install all the ota updates (a lot) until your version is 7.19.401.30. Then you can use the phone like this or you'll be ready to flash a lollipop custom rom. Otherwise you can go like suggested above but with older (JB or KitKat) Sense rom or any CM/AOSP roms.

Thanks guys.
but i think i might need some more help.
i downloaded the sdk manager to install TWRP, but when i try to write "adb reboot bootloader" it says "is not recognized as an internal or external command, operable program or batch file" (not entirly sure if this is the correct translation, in german it says the command is either wrong or could not be found)
i think it could be because of some driver issues.
any advice??

Download the android sdk tools:
https://developer.android.com/sdk/index.html#Other
Make sure you have the latest htc drivers installed:
http://www.mediafire.com/download/2lyl151pt5pah2v
Make sure you don't have HTC Sync installed on your computer, if yes, uninstall it since it will interfere with fastboot/adb commands
To use adb or fastboot commands, open a command window from the same folder where adb.exe and fastboot.exe are located on your computer (C::\Programs\Android SDK Tools\platform-tools). To start a command window from this folder, hold your left "shift" key and right click a blank space in that folder, then in the contextual menu, select "open a command window here".
Don't forget that adb commands can only works when the phone is booted in the OS with "USB debugging" turned on from the developer option menu or from a custom recovery. Fastboot commands only works from the bootloader (in the fastboot menu).

Well without any connectivity to the phone there is nothing we can do unfortunately. Might worth to try on another computer. Otherwise if you are 100% sure that the problem isn't the usb cable, the drivers or the computer then the phone usb port might be broken. This can be replaced (probably the "easiest" part to replace on that phone), you'll need to open the cover and replace that small usb/front mic board.
But the fact that your phone says FASTBOOT USB when in bootloader makes me believe its more a driver/computer problem since it would only says FASTBOOT if there were no connection detected...

thanks a lot for your help. I don't think I will get it working again anytime soon.
But i will look for a way

Trying to flash twrp recovery...getting error "target reported max download..."

Trying to flash twrp recovery...getting error "target reported max download..."
I'm trying to install twrp recovery but getting the error message: Target reported max download size of 536870912 bytes; error: cannot load 'twrp.img': unknown error
The phone was previously unlocked and rooted on lollipop....had problems and restored...took OTA update to Marshmallow 6.0.1
Any ideas? Please and thanks!

1) how are you trying to install TWRP?
2) You are using the most recent version from our official TWRP maintainer?
January 12, 2017
twrp-3.0.3-0-Mod_01-quark.img
https://www.androidfilehost.com/?fid=745425885120699982
3) And you are showing known file extensions in Windows? Do you know what that means?

If you have a jpg or pdf, and you see a file name -- do you also ALWAYS, ALWAYS see the extension like jpg or pdf? Default in Windows -- for idiotic reasons -- is to "hide known file extensions".
Make sure that box is UNchecked in your Windows settings. Because otherwise you are re-naming TWRP as TWRP.img(.img). You do NOT have to type the .img part, it's ALREADY an .img file.
That may or may not be your issue, but it messed up a lot of people in the past. ADB couldn't find TWRP.img because they had unknowingly called it TWRP.IMG.img -- because they couldn't see the file extension and thought they needed to add it to the file name.

1. I had the previous version 3.0.2-0...will try your link.
2. I unchecked the extension box...
will try again and let you know...thank you!

Just tried with the changes....still getting same error messages.

When you unchecked the extension box, what is now the visible name of your TWRP file? Does it say TWRP.img.img or just TWRP.img? Besides unchecking the extension box, you also need to make sure you are typing the actual name of the file. IF you had typed "TWRP.img"(.img) before, you now need to re-name it just "TWRP".img.
If you confirm that's not the issue, then we'll get @bhb27 involved over in the Quark TWRP thread.

I changed the filename to twrp and I'm using the command: fastboot flash recovery twrp.img and I've tried every other combination of twrp.img.img, twrp, etc just to make sure I wasn't missing something!
My goal is to be able to flash a new build.prop to allow for tethering...if there is a way to do that without installing twrp, that would be great

OK, just as a test, do this. Forget the name TWRP. That's just a convenience. Call it something else. Rename it box or chair. I'm not joking. Then, in your PC, what file name do you see? IF you renamed it "box", you should see box.img. You do NOT type .img. It's just the extension that should already be there!
then flash: fastboot flash recovery box.img
I'm suggesting this because somehow, somewhere it seems your file name is messed up?
Also you have done all this too? Permissions and stuff?
Enable USB debugging on your device:
Open Settings on your device.
Go to About phone and tap seven times on Build number, this will enable Developer options.
Now go back to Settings and you’ll see Developer options there, open it.
Tick the USB Debugging checkbox.
Connect your device to the PC. And type the following into the command window we opened to boot your device into bootloader/fastboot mode:
adb reboot bootloader
└ If you get a permission dialogue on your device to “Allow USB debugging”, tap OK.

Maybe revoke those permissions and re-enable them?

Renamed it "dummy"....the name I see on my file list is "dummy"......Still getting same error message. I tried recovery dummy.img and recovery dummy....still same error.
adb reboot bootloader works....cant flash the recovery image though. Do I need to do something else on the phone side prior to flashing the image? It has the android laying on its back with the "Start" option showing on top...

I was just suggesting you revoke the USB permissions and re-enable them in Developer Settings, just to make sure. That's the only thing I'm aware of you need to do on the phone side... If anyone knows something different, feel free to correct me!
@bhb27 is our TWRP maintainer for our official TWRP. So, I'm mentioning him here so he'll see this issue. Maybe he'll have some ideas?
Also, you you can post this issue over in the Quark TWRP thread. You can put a link to this thread in your post, so people can see what all we've tried.

Didn't recognize that command...here is the screenshot

You can't just flash a file called twrp and that's it. It needs to be twrp.img. Also, in order for mfastboot (or any other .exe file) to work in a command prompt, you need to navigate to the folder that it is present in. Is mfastboot.exe located in C:\Documents and Settings\Jason? If not, that's why it isn't found.

Right. His screenshot is showing other extensions, like .exe, .txt, .dll -- so his TWRP extension should be .img. It's missing.
What I cautioned him about was double naming the extension -- TWRP.img.img, which can accidentally be done if you have your Windows settings to hide known file extensions. Since his file extensions are no longer hidden, his TWRP file should say TWRP.img.
But naming it TWRP is just a convenience instead of using the regular file name like "twrp-3.0.3-0-Mod_01-quark.img". It's easier to type TWRP.img in the Windows command box than that long official file name. You could easily also re-name it "chair.img" or "box.img" as long as you were re-naming the correct file. I even suggested he do that because he seemed hung up over the TWRP name.
At this point, he probably needs to also re-download the TWRP file and re-name it. Now that he can see file extensions, it should automatically have the .img extension.

Me again...the guy who probably shouldn't be messing with his phone
I got TWRP installed. Tried flashing a zip for tethering...upon reboot it was getting stuck at bootloader warning screen. Eventually tried a wipe through TWRP (data, cache, and dalvik) and a factory reset through the phone menu, but still keeps getting stuck at bootloader. I can still get into TWRP, but not sure where to go from here
Do I need to do the wipe differently? Anyway to get past the bootloader screen?

I'm going to hazard a guess here that you also flashed SuperSu in TWRP and you are running the new Marshmallow update. (Yeah, confirmed, I just checked your first post. You took Marshmallow update.) In which case, it sounds like you flashed the wrong version of SuperSu. You have to flash an older version for initial root or your phone will stick at the bootloader warning screen. This has been discussed in all the Marshmallow threads.
What version SuperSu are you using? If on stock Marshmallow or stock-based Marshmallow ROM, the one required is BETA-SuperSU-v2.62-3-20151211162651). You can boot into TWRP, plug your phone into a PC and drag it over like a flash drive. It will show up in the root folder. Flash it, wipe all caches, reboot.
I've attached it to this post.
AFTER initial root, and after you successfully boot, then you can update to newest version of SuperSu. You just need it for initial root and to successfully boot the first time.
PREDICTION: Your next question will be how to get rid of the unlocked bootloader screen. Because you will see it every time you reboot your phone. When you do, here's your answer. But first, you need to flash the correct SuperSu to get past the bootloader screen.

Congratulations on installing TWRP.

[Android 11] Unofficial Lineage OS 18.1 for A21s

WARNING + DISCLAIMER:
By installing this custom ROM, you are VOIDING your warranty. Also, installation of this ROM WILL TRIP KNOX PERMANENTLY, and render apps such as Samsung Health, Private Folder, (+ any apps that depend on KNOX) useless until you get the phone's motherboard replaced at the Samsung C/S center.
Although this software is released in the hope that it will be useful, there is NO GUARANTEE that installing this will not cause any harm to your device. I TAKE NO RESPONSIBILITY FOR ANY BRICKED DEVICES, DAMAGED HARDWARE, OR ANY OTHER PROBLEMS CAUSED BY THIS ROM. You are using this ROM at YOUR OWN RISK. I strongly recommend that you DO NOT continue to the steps below UNLESS YOU FULLY UNDERSTAND WHAT YOU ARE DOING.
While this ROM has been tested with South Korean variant of Galaxy A21s (SM-A217N, CSC changed from LUC->SKC), please keep in mind that it hasn't been tested on any other variant (such as A217F, A217M.)
Click to expand...
Click to collapse
I would like to express special thanks to all the developers who contributed to the LineageOS port for Galaxy Tab S6 Lite + all the other developers who contributed to sepolicy & hardware parts for Samsung SLSI (Exynos) devices. Porting LineageOS to A21s would have been much harder without them.
Click to expand...
Click to collapse
After doing some research on this device, I was able to port LineageOS. The original sources are based on Galaxy Tab S6 Lite Wi-Fi version (gta4xlwifi), with some heavy modifications made for the A21s. In the process, I was able to fix some of the problems that were found on GSI (MTP, Fingerprint removal issues, NFC, Wi-Fi hotspot and direct), and added in some enhancements to the kernel.
Unfortunately, installation of this ROM requires Lineage Recovery, and since FBE (File-based-encryption) is enabled by default, it is incompatible with the TWRP.

NOT WORKING:
- Cell Broadcast (Emergency Messages) is broken in South Korea. The phone shows notifications, but the messages appear broken. Not sure about other countries. FIXED in South Korea as of 2021/9/2. However, its functionality in other countries hasn't been tested.
- Samsung's Proprietary Apps
- In order to use Wi-Fi Direct, you need to install a Wi-Fi direct sharing app from Google Play, as LineageOS doesn't have a sharing app installed by default
- Auto Brightness (The phone doesn't have the sensors for it anyway)
- On very rare occasions(probably once in more than 20 boots), the device's RIL (Phone calls, Data) might start up late when booting. If you see "No service" after booting, please wait for 30-60 seconds.
- VoLTE & VoWifi(not tested) - Unfortunately, this is located deep within Samsung's framework. AOSP-based roms for other Samsung devices don't support it either. Someday, this might be fixed.....
WORKING:
- Everything Else
GITHUB:
Device Source Tree: android_device_samsung_a21s, android_device_samsung_universal3830-common
Kernel: android_kernel_samsung_universal3830-common
Instructions for Installation:
1. BEFORE INSTALLING, make sure that you have UNLOCKED the bootloader of your device. This is a great guide that show how to do it. Also, the phone must be on the Stock ANDROID 11. If you are on binary U6, please use the recovery tar for U6.
2. Download the Lineage Recovery, ROM, Google Apps, ADB, and Odin. Unzip ADB and Odin to somewhere appropriate.
- ROM
- Recovery / Recovery(for U6)
- Google Apps
- ADB
- Odin
3. Enable USB Debugging on the device. Go to settings->About phone->Software information, and tap the build number several times until you see the notification that the devloper settings have been enabled. After enabling developer settings, go to settings->developer settings and check USB debugging.
4. Open Command Prompt, and type "cd <the path where you saved ADB to>".
4-1. As a test, type "adb devices". After typing it, the phone should show a screen that asks you to grant permissions for USB debugging. Select Yes.
5. On the phone, start holding down the Volume Up and Down keys. KEEP THE KEYS PRESSED UNTIL THE PHONE REBOOTS AFTER YOU TYPE THE COMMAND IN THE NEXT STEP.
6. While holding the keys down. type in the command "adb reboot recovery" on the command line.
11. After the phone reboots into download mode, press volume up to continue. Make sure that you see the "OEM LOCK: OFF" before continuing.
12. Open Odin. After opening Odin, click on AP, and select the Lineage Recovery Tar file that you downloaded in the step 2. After that, click on Start.
13. After a few seconds, if everything goes well, Odin should show "PASS" and the device should reboot into Lineage Recovery. After the device enters recovery, tap on Apply update->Apply from ADB. In some cases, touchscreen may be unresponsive or slow. If that happens, use Volume Keys to navigate and Power key to select. KEEP THE DEVICE CONNECTED TO THE COMPUTER.
14. After choosing Apply from ADB, type "adb sideload <the path where you saved the ROM file>" on the command prompt and press enter.
<CONTINUED ON THE NEXT POST>

15. If everything goes right, the device should show "script succeeded: result was [1.000000]" While ADB may show errors such as "Failed to read command" at 47%, this is no problem as long as the device says that the script succeeded.
16. Now it is time to install Google apps. On the phone, tap on Apply from ADB again, and on the computer, type "adb sideload <the path where you saved Google apps to>" and press enter.
17. After about 1-2 minutes, installation should be complete. Again, ADB might show "Failed to read command" errors. As long as the phone says that it was success, this is no problem. After installing, click on the "back" icon shown below.
18. Choose Wipe data/factory reset, and reboot the device.
19. If everything went well, the phone should reboot into LineageOS. Set up the device and Enjoy!

ADDITIONAL TIP: HOW TO ROOT THE PHONE ON LINEAGE 18
On Lineage 18, I patched the kernel so that it would have no problem with the official Magisk app.
Therefore, you DON'T need to use a version that has been modified for A21s.
If you want to have root, you can get the Official Magisk App.
1. Download & Install Magisk from the official source.
2. Select Install. When it asks you to select the boot image, choose the boot image from the Lineage OS ROM file that you downloaded from the step above. After patching the boot image, move & rename it to something you can type easily (ex. /sdcard/rooting.img)
3. Enable developer settings (Settings->About phone->Tap on build number)
4. Go to developer settings and enable USB debugging & root permissions for usb debugging.
5. Connect the phone to the PC.
6. Open the command prompt, and type "cd <the folder where you installed adb>. After that, type "adb root". If the phone asks you for permissions for USB debugging, allow it.
7. After the adb shows "Restarting adbd as root", type "adb shell dd if=/sdcard/<the path to saved boot image>" of=/dev/block/by-name/boot". The output should be something like
" *** records in
*** records out
*** bytes (** M) copied, *** s, **M/s"
8. After seeing the output above, reboot the phone. After rebooting, it should be rooted.

Good news. Thank you very much

Then, my friends, write here how it works and thank you for your observations

Thanks for your work buddy.....
I got Magisk installed an easier way...
Download Magisk Canary .apk
Change .apk to .zip then install the same way as the Rom and Gapps, by ADB sideload.
Factory reset/Format data and reboot.
Done
All we need is a working TWRP.... I've got one working but it shows no files and won't mount anything..... e.g. system, data etc

If you're on U6, there's a chance that Odin might fail on vbmeta.
A possible solution is:
1. Download Magisk (version doesn't matter)
2. Download the U6 firmware that you're on
3. Using Magisk, patch the AP tar of U6 firmware
4. In the Lineage recovery tar file that you downloaded from above, replace the vbmeta.img with the one from Magisk-patched AP tar file
5. Proceed with the installation as written above
A more fail-safe method would be:
1. Root the phone using a patched Magisk app
2. unpack the recovery.img in the Lineage recovery tar file and copy it into your device's SD card
3. Enable USB debugging on the phone, and connect the phone to adb
4. Using command prompt, type
"cd <path to adb>"
"adb shell"
"su"
"dd if=/sdcard/<path to lineage recovery image> of=/dev/block/by-name/recovery"
"reboot recovery"
After typing these, your device will reboot into Lineage Recovery. After entering recovery, select apply update->apply from adb, and proceed with the installatiom above from Step 14.

nice thankyou bro

Or you can extract just the boot.img from the AP.tar. Patch it in Magisk then repack in the AP and flash with Odin

Thank you for your review. It's such a great news that it's working on U6.
Yes, PUBG is a hell of a game, Krafton has done such a great job with it The kernel has newer mali graphics driver (R26P0 -> R31P0), maybe that could've done the trick (or it may just be due to LineageOS being much, much lighter than One UI)
How is the battery? While I wasn't able to find any abnormal battery drains (both in standby and stress conditions), I'm concered about how it would perform in other devices.

First look on A21s LineageOS 18.1

hi,so i get this message "only official released binaries are allowed''in download mode,after the vbmeta failed...
SM-A217F/DSN
and in frp hijacker i get ''check device connection or com ports''

Update:so i succeded to hijack my phone after the error but it wouldn't boot into recovery,and i got everytime a screen with a warning that my phone is not using samsung's official software,and when i press the power button to continue,like it shows,it boots automatically into android.
So what should i do?
And do i need root to do this?

How To Guide [GUIDE] Beginner's guide on how to root Redmi Note 10 Pro (sweet) without TWRP

I decided to make this guide since I didn't see a guide thread which explains how to root the phone.
DISCLAIMER: I am not responsible for ANY damage that occurs to the phone, you getting fired because the alarm app failed or the world getting nuked, etc...
Requirements:
-A unlocked bootloader (if you don't know how to unlock it, search "How to unlock bootloader Xiaomi"
-boot.img extracted from your phone's fastboot rom (MAKE SURE YOU DOWNLOADED THE EXACT SAME ROM THAT YOUR PHONE HAS (Check "About phone" in settings. Make sure that the version AND the code (RK(something)XM) match, if you have MIUI).
xiaomifirmwareupdater site contains unmodified MIUI roms for your device.
-If you have a custom rom, extract the rom's zip and get the boot.img from there.
-ADB and Fastboot drivers installed on phone and PC
-SDK Platform tools downloaded from official android website. Extract the downloaded zip to desktop and rename it to platform_tools
-A Computer
-Basic understanding of CMD, ADB and Fastboot commands.
-The phone
If you see an error, scroll down to the troubleshooting section.
Steps:
(on the pc)
-Copy the boot.img file to the phone's downloads folder
(in the phone)
-Download the magisk app from the official github site
-Install the app, then open it.
-In the app, select install on the magisk card

-Select patch a file, then find and select boot.img.
-Tap "let's go".
(on the pc)
-Connect your phone to your PC and copy magisk_patched.img from the phone (should be in downloads folder) back to the pc.
-Rename the file to magisk.img, then move it to the platform_tools folder which contains fastboot.exe.
-Now reboot the phone and when the screen goes fully black, hold volume down button until you see "fastboot".
-Your phone should now be in fastboot mode. Connect the phone to the pc.
-Press win+r, then type cmd
-Type cd desktop
-Type cd platform_tools
-Type fastboot devices (if you see nothing, make sure you have adb and fastboot drivers, that the phone is connected and is in fastboot mode.)
-Type this carefully: fastboot flash boot magisk.img
-Done! Now reboot the phone by typing: fastboot reboot
-If you did everything correctly, the magisk app should say that it is installed.
TROUBLESHOOTING:
Q:Fastboot says it couldn't find "magisk.img" or CMD says fastboot doesn't exist
A: Make sure that cmd says that its in C:\Users\(name)\Desktop\platform_tools and that magisk.img is also in there.
Q: Phone is in bootloop
A: Hold volume down button until phone is in fastboot and flash stock boot.img with fastboot flash boot.img. (You will not have root access) If the phone is still somehow in a bootloop, execute the flash_all_except_storage.bat script by double clicking it (found in the sweet_(region)_images folder you extracted from the full fastboot rom .tgz file).

Very good but easier with unlocked bootloader and flashing twrp via adb flash recovery "name of twrp file". Afterwards you can flash directly magisk (I prefer 23 canary debug apk) to root.

if i may add to the troubleshooting: if it says magisk.img isn't found, just type this (after confirming connection with fastboot devices command:
fastboot flash boot
then drag and drop the patched magisk file onto the cmd window/line where you typed the command above. worked for me.

Tanks you

For beginners, "assuming bootloader is unlocked if not click here" should be mentioned.

I've searched around, and it seems to be caused by a VPN. If you use a VPN, turn it off and try again. If not, it could be that the Xiaomi unlocking API is down temporarily.

No need to flash lazy flasher since you already flashed Magisk. They both do the same which is to disable dm verity. Also, lazy flasher is an old zip intended for old devices so maybe that's why it failed.

Softbricked Razer 2 using "fastboot flash recovery twrp.img"

Here were my steps with Razer 2:
SUCCESS: Developer Mode USB Debugging
SUCCESS: (CMD) fastboot flashing unlock
SKIPPED BY MISTAKE: (CMD) fastboot flashing unlock_critical
SUCCESS: (CMD) fastboot flash recovery twrp.img
SOFTBRICKED: TWRP.img flashed on recovery partition alerted Google Security AI
So, I received the error in this picture:

"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",

RAZER 2 SOFTBRICK ERROR
I did not unlock bootloader partition access, so when I use flash_all.bat, the script does not successfully create the hard drive partitions.
Strangely, it still tries to install system files on both A and B partitions (the Razer 2 uses A-B partitioning).
Of course, since creating the partitions failed, when the system.img flash reaches file 6/6 on partition B it has no partition to send the files to, so the script kicks me out.
Since the phone is softbricked, the phone does not show up on my drivers list either. The computer can flash the script, but it does not recognize the device is there at the same time:
fastboot devices: Visible
adb devices: not visible
It said Razer 2 in device manager prior to bricking, and changed to ADB interface while in bootloader mode after installing the correct USB Drives (Found on the Razer site). now it doesn't even show that the USB port is active.
I found a forum online that suggests using the CMD command to remove the error:adb reboot "dm-verity enforcing"
However, it failed and spit this error out:
adb reboot "dm-verity enforcing" Failed. Error: no devices/emulators found
I'm wondering if it because the computer cannot see the phone in device manager.
Or maybe it's because I don't have the patch they are talking about on the XDA forum. I am still learning and not familiar with what patches are. I know some bug fixes are called patches but aside from that I don't know how to use them. This was the patch link they sent that they said you need for the command to work:
https://github.com/invisiblek/andro...mmit/e1f62399183b854144301ce85f3a33b53ebfdde7
I also tried:
CMD: fastboot flash boot boot.img
CMD: fastboot flash boot_a boot.img
fastboot flash boot_b boot.img
This did not erase the error either.
Apparently, some phones did away with the recovery partition post 2016 (my razer is Dec 2020).
They flashed the recovery partition inside of the boot Kernel in newer phones instead of having a separate recovery partition with its own Kernel.
I also discovered that my phone's firmware (Found directly on Razer 2 Site) does not have an existing recovery.img file to even dirty flash to erase the TWRP file.
So naturally I am assuming that there ISN'T a recovery partition to flash the img file onto in the first place. This also explains why I am able to still use recovery mode on the phone even though I bricked it by flashing TWRP and replacing the stock recovery.img.
So CMD: fastboot flash recovery recovery.img is useless (I already tried just in case)
So now I have this TWRP file floating on the hardrive somewhere and do not know how to get rid of it if these 3 methods don't work.
So if the TWRP.img was not successfully flashed onto an existing partition (and bypassed security successfully), then I would imagine that flashing the original boot.img would not help which is why it did nothing.
If anyone knows how to get my device to get recognized while in this error mode that would help. Then I can figure out how to use the patch to get the CMD command to work to wipe the boot error.
I used CMD: fastboot flashing get_unlock_ability, and it spit out a zero (Meaning it can't be). So I need to change that to a 1 somehow with some voodoo tech magic.

Seems like you're making a lot of assumptions here. There is no "Google AI security". This error message means there's a dm-verity corruption error: Android Boot Flow
This is probably because you attempted to flash an image without properly unlocking the bootloader, so what you flashed does not match the verification signature.
I'm not familiar with the Razer 2, but if it's an A/B device (meaning it has A/B slots) it most likely does not have a recovery partition. The recovery kernel is compressed into the boot image, which contains the ramdisk and system kernel as well. It is not possible to directly "flash" portions of the boot image; any image flashed to /boot will completely overwrite the contents of the /boot partition.
It is important to note that due to the compression used for the recovery kernel, there is no custom recovery that can replace the factory recovery unless the entire boot image is replaced - i.e., LineageOS. TWRP does not support the compression necessary.
Remember that adb commands only work in recovery or system. You have to use fastboot commands in bootloader or fastbootd, and you must have the correct driver installed to interface with your device in bootloader/fastbootd mode.
If you're able to boot into bootloader, try the correct command to unlock bootloader on the critical partitions: fastboot flashing unlock_critical

I did try that but I get this error:
View attachment 5880855
So I think the dm-verity issue is locking me out of the access to use that command.
Also, I meant the Google AI Security that flags it as a dm-verity. This video also explains that it places the app in the boot Kernal (which is accessible still), which is how I think you are able to work around getting TWRP on the phone.
This is where I got my info:
(watch @ 4:00)
(watch @ 6:00)

Again, there is no "Google AI Security". Dm-verity is the first thing executed by the kernel - it compares a hash of the boot image against a reference hash. See Dm-verity
This should not matter on an unlocked bootloader; the only thing the bootloader checks is for a valid boot image header.

It might be misinformation then on the video. I don't know but I guess it's not relevant either way.
Valid boot image header?
Any ideas why I am getting the error:
No adb devices/emulators found?
The phone isn't even showing when I use Diskpart on CMD to search for Disks.
I can't use an ADB command if it can't communcate with the phone. I ws going to try to use the command:
adb connect [USB port name]. Only fastboot works.
I saw someone connect that way when it was not showing. other than that I don't know how else to get my CPU to recognize my phone. Any ideas?

It depends. What command are you trying to use, and what mode is your device in when you're trying to use it? This error means that ADB is not able to detect a device that is either in recovery mode or Android system. If you try to use ADB commands in bootloader/fastboot mode, you may get this error too.
Pernilex said:

Why would it? Diskpart only shows currently mounted partitions, so this would only work if the PC detects the phone as attached storage.

Of all the ADB commands I'm aware of, "connect" is not one of them. Any connected ADB device will show up in adb devices

Try fastboot devices with the phone in bootloader mode, if nothing shows up you probably have a driver issue.

fastboot devices recognizes my phone.
adb devices also recognized my phone and so did device manager before I soft-bricked the phone.
So definitely not a driver issue.
ADB devices only recognized my phone when I selected USB file transfer while my phone was on the home screen and I could actually boot into it.
Before I bricked it, my phone's drivers were only recognized on the device drivers or under adb devices when the phone was in file sharing mode. My phone was never visible in adb devices while in bootloader/fastboot mode, so I assume this is what you are getting at.
I had forgotten that this was how I entered ADB device manager before I bricked it.
I'm assuming I have to turn file transfer on again somehow while stuck on bootloop without access to the User Interface.
Then once file transfer via USB Debugging is active, I can use the ADB command to disable dm-verity and get out of the loop.
Then I can double unlock the bootloader the way I was supposed to the first time and unlock internal storage access, not just the bootloader itself.
Then I will have access to the storage partitions so the phone will flash_all correctly and not try to flash the system image onto the phone without a partition and kick me out of the script.
Question is, how do I turn on file sharing with only access to fastboot? My phone is locked again right now (I re-locked it trying to follow a bootloop troubleshoot guide). It is now showing the same error as the fastboot critical_unlock command and saying I cannot do that.
So obviously remove dm-verity needs to come first after I enter file sharing mode. Then I can follow the proper double unlock steps.
Is there a fastboot command to re-enable USB debugging?
For example (ignore validity of commands this is just an example of steps):
1. fastboot enable USB debugging
2. fastboot boot USB file sharing / fastboot switch to ADB
3. fastboot disable dm-verity (bypass bootloop)
4. fastboot oem unlock bootloader
5. fastboot flashing unlock_critical (parttion access)
6. Fastboot flash_all (Razer 2 Stock ROM)
PS: I thought anything plugged into a USB port, HDMI port or a second hard drive port would be recognized by DIskpart. I did not know it was only for storage. I learned how to access it when I was teaching myself how to put windows ISO on a flash drive to reset my PC offline. That being said, if the CPU had access to my Razer's storage, wouldn't it show up like a flash drive would if it was hooked up to USB?

Were you able to get the issue fixed? I am currently having the same issue
