Which step you want to do? I do not have OTG, so I did everything by ADB.

If you want to send the extracted files:
adb push ./src_dir/* /sdcard/twrp/BACKUP/dest_dir

If you want to twrp restore:
adb shell
twrp restore /sdcard/twrp/BACKUP/dest_dir

Everything works but anything involve voice not work for me. I really need you guys advice how I can get voice input (keyboard).

Is there a secret to get Netflix working on this? The documentation is clear as mud, been rooting for decades, been lost all damn day.

Not only that, xda won't let me sign in under my nick, which has thousands of posts and been with xda since Windows mobile.

I've been spending some time working on a similar ROM/Backup from scratch, built on fire OS version 6.2.8.0
(Highest without efuse burn)

Using the latest files (AFTV-MM-20221021) supplied by @tsynik.
Latest Kernel supplied by @Pretoriano80
NTFS/F2FS/EXT4/exFAT OTG supplied by @Pretoriano80
Updated magisk (25.1.FTV)
Updated Leanback Launcher
Updated Xposed
Other Apps updated.
Some frozen Amazon apps, no OTA update etc. (non destructive debloat)
No play store/services (unnecessary and causes issues)
Quick menu on double click Home (Xposed Edge)
Build.prop tweaks (fast boot etc)

Everything working well so far.

If anyone is interested I can make a clean backup and start a new thread. I've reached out to the OP but believe he/she has not been active here for sometime.

Will need to make a backup clear of any credentials.

Does anyone know if there are any apps I can't include following XDA rules? (Cinema, CyberFlix etc)

Let me know if interested and I'll put something together.
It's been two months. Where can we download your rom?

I have been using this ROM for over a year. However, recently I started having issues with Netflix. The app works, but quits every time to launcher or black screen after several minutes of playback. Is this issue related to the ROM, or app? How can I fix it? I tried clearing Netflix Data and Cache, but did not help.

    After so many trial and error, I've finally saved the latest version of my system with TWRP backup. I want to share this personal setup with you guys since it required a lot of work to debloat, install add-ons, apps, kernels and tweaks. This is a single package that contains many modifications from other threads made for simple, one-time installation. I tried to keep it close to Android TV (Nougat) exprience. However, I kept some of the Amazon software that I use like Alexa and Amazon Appstore.

    Guides I found and used for this rom:
    !!Please read these threads before you begin!!
    !!All credit goes to those developers!!
    !!Do at your own risk!!

    Some Info:
    Android Version: 7.1.2​
    Fire OS Version: 6.2.7.6​
    Working TWRP Version: 3.3.1-0​
    Installed Magisk Version: 20.4​
    Installed launcher: Google Leanback Launcher​
    Available Internal Storage after installition: 3.15 GB​

    Screenshots:
    top.pngbottom.pngrecomendations.png

    Contains:
    ==========================================================================================

    Working:
    • Alexa
    • Voice Input of Amazon keyboard. (need to enable FireTV IME Keyboard from settings) (long press menu button for quick switch)
    • Amazon Settings
    • Fire TV Remote App (I highly suggest this app. Works perfect for navigation and keyboard input)
    • Amazon Appstore (You can install your previous paid apps from here. Search function in amazon appstore only works with alexa)
    • Google Play Store and Services
    • Magisk
    • Xposed
    • Recommendations on launcher
    • Widevine DRM (Netflix, PrimeVideo etc. works fine)
    • Kodi Audio Passthrough
    • Android Screen Cast
    Not working:
    • Google Assistant
    • Google Voice Search
    ==========================================================================================

    Some useful apps that I installed (all can be uninstalled):
    • FX (file manager with root access)
    • Link2SD (app manager with root access. It lets you uninstall, freeze system apps or convert them to user apps and vice versa)
    • Xposed Edge (simple alternative to tasker or key mapper with root access. I've mapped long-press of back button to kill foreground app)
    • LeanKey Keyboard Pro (came with tsynik's magisk module and I loved it)
    • Smart Youtube TV (modded youtube app that enables dozens of options. I'm using it to increase the playback speed of videos)
    • MX and VLC Player (to play local or online streams)
    • Aerial Dream TV (really nice screensaver that uses Apple TV visuals)
    • Prime Video, Netflix, Spotify (not to make the launcher look empty)
    Installed magisk modules:
    • Xposed Framework (rovo89)
    • Google TV Apps for FireOS 6 (tsynik)
    • FireTV4k Selinux Fix (Pretoriano80)
    Installed xposed modules:
    • Xposed Edge
    • AFTV-XM (tsynik)
    • AFTV-GAPPS-XM (tsynik)
    ==========================================================================================

    Requirements:
    • OTG Adapter
    • USB Keyboard/Mouse
    • USB Stick Formatted Fat32
    • TV or Monitor
    • Firestick 4K
    How to install:
    1. Be aware that your warranty will be void.
    2. Backup your files.
    3. Unlock bootloader and install twrp using this guide.
    4. Download and extract Firestick 4K Android TV TWRP Backup.rar to TWRP backups path on USB stick; TWRP > BACKUPS > G070VM0984752N1Q
    5. Do a factory reset via TWRP (use otg adapter and keyboard/mouse to navigate)
    6. Restore from TWRP backup that you prepared.
    7. Reboot to system.
    8. Connect to wifi and log in to your amazon account. (still using keyboard or mouse to navigate)
    9. Go to Settings > Fire OS > Controllers and Bluetooth Devices and pair your Fire TV remote. (now you can ditch the keyboard)
    10. Enjoy.

    Additional Notes:
    • Developer options and USB debugging enabled.
    • OTA updates disabled.
    • Disable "Stay Awake" option in developer settings if you want the screensaver to start.
    • Long-press to back button kills the foreground app. It makes quitting activities easier.
    • Long-press to menu button opens fast keyboard switching window. It helps to switch to amazon keyboard when I use voice input.
    • You can change the launcher to whatever you want. I'm happy with Leanback Launcher. I didn't try but there's this.
    • Important: Never install magisk updates from magisk. Use TWRP.
    • If you want to create TWRP backup, select "System Image" and "Vendor Image" insted of system and vendor.
    • Suggestion: FX Web Access makes it easier to tranfer files.
    • Suggestion: I think keyboard from FireTV remote app and alexa's speech to text input are the most efficient input methods if you don't have physical keyboard.
    • Important:
      Play Store downloads not fully compatible with Amazon download manager. In case apps won't install from Play Store - uninstall Play Sore updates from ATV Settings.
      NOTE:
      You need to remove and readd Google account after module update.
    • Installed Netflix and Spotify apps are compatible with alexa.
    • I couldn't make my dualshock 4 controller work with this device. Even with the stock system. Help would be appreciated.

    • @k4y0z and @xyz` for unlocking the bootloader.
    • @tsynik for building those life-saving magisk modules which is basicly the key of this build.

    • @bnevets27 for debloating script.
    • @Skel40 for build.prop tweaks to increase performance.

    It's possible to interact with this ROM on first boot without a keyboard. You must use adb shell over USB. The USB cable connected to your laptop, and the FireTV Stick plugged into HDMI on your monitor.

    1. First make sure the device is booted and you see the FireTV stick over USB with adb with adb devices.
    2. Open a new shell with adb shell. You should see a prompt showing mantis:/ $ (may differ if you're not using a 4K stick.)
    3. You have multiple options now to interact with the UI.
      • input keyevent <number> which allows you to send keypresses to the device as if you were working with a keyboard.
      • input mouse tap <x> <y> which allows you to click things on screen using a grid of coordinates. The top left of your screen is x=0 and y=0. The bottom right of your screen is x=1920 and y=1080. Figuring out the exact coordinate of where you want to click will take some trial and error. Don't be afraid to try. Add more x to make the mouse click something right. Add more y to make the mouse click something in the direction of the bottom of the screen.
    4. The easiest option is to use the keyevent input.
      • Use the following guide to map your keypresses to numbers: https://stackoverflow.com/a/8483797/6252246
      • Examples:
      • input keyevent 19 - Up arrow on keyboard
      • input keyevent 20 - Down arrow on keyboard
      • input keyevent 21 - Left arrow on keyboard
      • input keyevent 22 - Right arrow on keyboard
      • input keyevent 66 - ENTER key on keyboard
      • input keyevent 29 - 'A' key on keyboard
    Your goal is to get the FireTV Stick on your home network by entering in the wifi password. Once it's on your network, you can then use the FireTV app on your phone to interact with the device. You can also navigate to the FireOS settings for Remotes and Controllers and unpair the non-existent remote ID which ships with this ROM. To do that start the pair process. When it asks you to press "select" on the 'old' remote (which you don't have) just press select (tap the pad) on your FireTV app and it will proceed with the pairing.

    Hope this helps someone without a OTG or keyboard like me.

    i'm doing experiment on this rom and google assistant seems to work (except voice search) , if you try to type it works. I bet it needs to be tweaked out , maybe removing/blocking alexa and reassigning the voice button on the remote to trigger google assistant

    EDIT:
    i was right, google assistant works. I've been able to use voice search and use it to control my smart home.
    to make it work:
    -enable google assistant in atv voice settings
    -go home and agree microphone usage trying to make a search
    -go in xposed edge pro
    -choose a button ( i used volume down for test) and set google assistant on a key ( it is under activity > google > searchactivitytrampoline (don't forget to enable button)
    -done

    how to use it:
    press the chosen button
    and press alexa micrphone button and it will work
