Stock FireTV 1st generation - stuck in boot

Hi,
My stock fire tv is stuck in boot process. When I turn it on loads the b/w amazon logo and, about 30 seconds after, the colorful amazon fire tv logo comes up. And that's it, nothing else ever happens. No reboot, noloop, nothing else.
I have tried to factory reset it by pressing alt+i+print-screen hundred of times while booting with no success. I have tried with 4 different keyboard (including a logitech k400).
I have tried to connect a USB-A to USB-A cable from the fire tv and the PC and installed adb drivers (all devices are recognized by windows and display and device manager) but I can't detect the device with adb devices at any stage of the boot process at all.
Does anyone have any other possible way to un-brick it? O any other suggestion to revive it?
btw, It "bricked" itself. One day I turned on tv and I saw empty menus and nothing happened if I tried to navigate on it... So decided to reboot it and... there you go, the way it is now.
Thanks in advance.

Anybody can help please? I've got a precious brick os plastic and circuits on top my desk right now....

1st Gen Fire TV always resetting after reset

Please help me
I reset my fire TV stick after it got slow and buggy. No root or modifications. Now it resets and switches off - no reboot :/ The remote won't switch on the stick so I have to reconnect the USB power. Then it starts again with the reset procedure.
Any ideas?
Thx

Fire TV Stick (2nd Gen) looping - can't use any of the usual methods.

I have a FTVS 2nd gen. When I boot it, I get the Amazon logo, then a brief black screen, then the "Fire TV . . ." screen.
Then, it goes to "Optimising system storage and apps - this may take up to ten minutes". It takes a lot longer than this; then it reboots. Rinse and repeat.
I have an OTG "Y" cable with a logitech K360 wireless keyboard (confirmed working), and a working remote paired to the stick.
I have tried "Back and right" held down throughout the entire boot process with zero response from the stick; I have tried ALT-FN-PrtSc-I repeatedly during the whole time it's on; I have also got funky and tried ALT Gr-FN-PrtSc-I, Alt-FN-Insert-I, and have tried throwing "CTRL" into the mix a few times too.
Nothing elicits any response from the stick. I don't think that the stick gets to the point of firing up the network stack, so there's no ADB via wifi; and of course I can't enable debugging via USB so there's no ADB by USB either.
Is there any way I can proceed? It's so old I don't mind opening it up if I have to, but that's a last resort.
TIA for informed responses.

Yes you can follow the thread "Unlock Root Twrp Unbrick Firetv Stick Tank" and once youve unlocked and rooted, flash a new fimware and start fresh.
Something has became corrupted in your sticks /system folder. Just take your time and follow the steps to the letter and dont be scared to ask for help if you get stuck.
Regards

Thank you my man, much appreciated!

OK, a combination of my shakes and my traditional mini soldering iron (HUGE compared to this circuit) I am unable to complete step 2 which is to short the CLK line to GND. At the risk of damaging my stick, I've given up.

Amazon Fire TV 2 and TWRP

Hello,
I just joined the forum this morning and wanted to say hi to everyone. Hopefully someone can help me here. I have an Amazon Fire TV 2 and it has been rooted and I have Teamwin Recovery Project 3.0.0-5 on it. It has been working for years, but one day a few months ago, I switched the TV input to the Fire TV and just saw the Teamwin splash screen sitting there and blinking. I disconnected the Fire TV and connected it to another TV and it booted up normally, however, without the option to select Boot Normal or Launch Recovery. I then disconnected the Fire TV again and reconnected it to the original TV, it did not boot and got stuck at the splash screen again. Finally after numerous attempts at restarting the device, it booted (without the option to choose Boot Normally or Launch Recovery). I used the Fire TV for a month or so and have restarted it a few times and always was able to get in, but still without the option to Boot Normally or Launch Recovery.
Last night, I was watching a movie and it ended. I tried to use the back button on the remote to go back to my Emby server to watch another show. The Fire TV was not responding and I did not see the white light on the Fire TV at all, but I still had the picture of the finished movie on the screen. I pulled the power plug on the Fire TV and plugged it back it. I'm back to the Teamwin splash screen and it just sits there and blinks every few seconds or so. I never get beyond it and cannot get back into my Fire TV. The white light on the Fire TV also blinks slowly.
I saw a post about the Fire TV 1 and a new 3.0.0-7 recovery that is supposed to resolve that issue, but I did not see anything for the Fire TV 2.
Anyone have any ideas or suggestions?
Thanks,
Chris

AFTV2 as in Model DV83YW? (found on the bottom of device).
If so, I've found that sometimes a faulty power cable can cause this kind of behaviour - try plugging the device into the wall & a computer/laptop (at the same time) with a USB-A to USB-A cable - for some reason allows the box to draw enough power to boot if the power supply is faulty.
If this doesn't work your power supply is probably fine - you could probably re-flash the pre-rooted rom and it would probably boot again, but honestyly I'd recommend unlocking your bootloader via the unlock.zip method (found here: https://forum.xda-developers.com/t/unlock-root-twrp-unbrick-firetv-2-sloane.4222331/) if you're running FireOS 5.2.7.2 or below, or the brick method if running 5.2.7.3 or above.
Of course, you will need to backup your /data partition via TWRP (to a external SD), but I think this is the best option for future proofing & would allow you to recover from something like this a little easier if anything were to happen to your AFTV in the future.

Thanks for the reply. Don't think it is the power cable as I have another power cable I had purchased a while back and it does the same thing with that, but I'll still try connecting it top the computer and see what happens.
I'll also try the methods you linked. Unfortunately, since I cannot boot into the Fire TV, I cannot determine what version of FireOS I'm running.
You mention backing up via TWRP, but I can't get into TWRP, that's the issue. It just sits there with there with the TWRP splash screen and it blinks. No options to boot normally or boot into recovery.
I try what you suggested and report back.
Thanks again,
Chris

Fire TV Stick 4k half dead open for suggestions

2 days ago I came back to my Fire TV Stick 4k only to find black screen with "loading..." letters in corner, and at that moment pressing home button did nothing, seemed that remote isn't working at first or device froze.
3 Hours before that I has using device, and only thing I did i power toggled it 3 times in few seconds using power button on remote (don't ask why it irrelevant now)
After I power toggled the device, and after "Fire TV" logo it stated that it can't find my remote. So i changed fresh batteries, tried to resync remote to device and all other stuff, but nothing helped. So I decided to try my remote on another device, and concluded that remote is perfectly fine and connects to other device without problems, and that it's nothing wrong with it.
At the same time it baffled me that device didn't load home screen after boot, just notification that it cant find remote and black screen after that.
Later I discovered that remote is in fact working (built in firmware restore functions and menu that is accessed by long pressing home button for few seconds).
So I decided to do factory reset by pressing key combination.
Factory reset menu came up, and after I pressed "OK" nothing happened, device didn't reboot.
Pressed key combo again, and let the timer for factory reset count down to zero.
When it came to '1' it froze.
Pressing key combo again factory reset menu would come again and do countdown from start.
I can also invoke menu accessed by pressing home button for few seconds, but what ever I choose from there it freezes, but if I press home button again it opens same menu again and move left-right and even enter "profiles", so it's not frozen, it just seems that it can't open any menu entry for some reason.
At he same time I can access it via wifi ADB and run ADB shell commands, so it is connected to wifi that has internet access.
I tried running "adb reboot recovery", device reboots, comes up with Fire tv logo and "no command" on screen.
It sits there for a minute and after it reboots and goes into normal boot.
I also tried "am start -n com.amazon.tv.launcher/.ui.SettingsActivity" folowing "am broadcast -a com.amazon.tv.intent.action.MASTER_CLEAR" but no avail.
it states "Broadcast completed: result=0" and that is it.
How do I factory restore / flash firmware, whatever ?
I will take any suggestion before tossing it into bin, because I think memory got corrupted somehow and device is processing and executing fine.
Edit 1 :
Safe mode method using USB keyboard on OTG cable doesn't work. Tried ctrl+alt+menu+prtscr+i several times, it invokes nothing.
Edit 2 :
Tried rooting using shorting to ground exploit, but it doesn't work since serial number of device is too high thus bootloader locked.
Edit 3:
I can see all the installed packages over ADB and uninstall ony of them normally.

Thank you for suggestion. The main question is how do I format USB stick to Android "internal memory" if I don't have Xiaomi 4K stick, like you mentioned in your original post ?
I have another working Fire Stick 4k, and have formatted USB stick using that device, but since Fire Stick 4k uses Fire OS 6, and possibility to format USB stick to "internal memory" is a feature of Fire OS 7, I don't think it will work.
At the moment I just formatted this stick using Fire OS 6, connected using OTG to malfunctioned stick, I can see Fire TV accessing it few times on boot (LED flashes), but after boot I don't see any activity. I will let it sit for a few hours.
