help my kindle is a brick

hi i was a bit dumb today, i deleted the os on my kindle fire hd 8.9 without any back up. anyway i finally got n2a to install a stock image via trwp, installed fine went through kindle set up then got a pop message to install superuser, i selected via trwp, rebooted then got red screen everytime i rebooted.
so i then retried to install n2a but it wouldnt as it got uninstalled. so i put the kfhd into fastboot and flashed a stock image via kindle fire first aide but it wont seem to install. so i am stuck with a kindle that i cant do anything with. at first when i tried installing via kffa it kept getting stuck at erasing userdata, now it seems to go the whole way through but nothing seems to have installed, despite it saying its complete.
as it stands it loads to kindle fire logo then i get a message saying your kindle doesnt seem to be able to boot. i have two options of reboot or reset to factory settings. tried both but nothing works. at the bottom of the screen i get E;failed to mount/cache ( invalid argument)
any help would be so much appreciated

My kindle is dead after the wipe on safestrap !

I follow some instruction on internet and after the wipe step on safestrap, my kindle is completely dead now. it wouldnt turn on anymore, keeping showing the kindle fire logo. I think It's been erased !
Are there anyway i could revive my kindle or is it ready to be thrown away ?
Please help. Thanx !
i have a similar problem, after a wipe data factor reset from safestrap and then flashing the thor gapps rom and making sure the rom slot was active(not the stock rom slot) but the rom slot that i flashed the thor gapps rom on and ,,,i rebooted the device as usual but it only booted to the grey kindle fire splash screen so i held the power button until it booted again but only going to the grey kindle fire splash screen again,,,so i tried to boot it to safestrap recovery using the volume buttons but it would only boot to kindle fire factory recovery,so i rebooted the kindle from there and back to the grey kindle fire splash screen it went, so i rebooted in to kindle recovery because safestrap was not coming up and it would only go to kindle recovery,so i hit the return the kindle to factory settings and when it was done it went back to grey kindle screen and thats all it will do,,,,when i plug it up to windows i get mtp in device manager,but the driver has an error saying device can not start error 10
and when i plug it up in ubuntu 12.04 and run lsusb in the terminal it comes up with an id and says Google Inc. but i can't get adb to recognize the kindle,,, i even checked adb with another android device to make sure it is all setup right and it worked,,,, i have read a few times in the forums here that you have recovered this device from many types of bricks and feel that if the grey kindle fire logo/splash screen is coming up that there is hope to get adb working,,,
any help is greatly appreciated and thanks in advance !!!!
oh and it's the kindle fire hdx 7 in tab

Kindle Fire HDX 7" 3rd Generation 64gb Boot Loop please help me!

Please help. My kindle Fire won't start. I power it on, and the white, static kindle fire logo comes on, then the screen goes black (but the screen is on, there is a slight glow to it).
My computer won't recognise it via usb, and I tried a factory reset in the recovery menu. Is there any way to fix it?
I think the problem might be that I edit the 'hosts' file in the root folder, to try and get google play working, and may have done this wrong.
Please help, and I thank you all a ton.

Factory Reset without ADB etc possible?

Hello,
I own a Fire HDX Saturn 8.9 with FireOS 5.1.1 that was rooted. Unfortunately I installed Greenify and after a reboot it seemed that it blocked the launcher I installed (Nova). I got to the point where the login page should appear but there was only the FireOS background (no login page) blinking randomly without being able to make a touch input, only the hardware button work (like shutdown).
I then thought ok, I will make a factory reset with ADB and start all over. I ran "adb reboot recovery" and got to the HDX recovery screen and made a factory reset. Afterwards I rebooted but the problem still remained with the "login page" (blinking screen). Unfortunately my root and ADB got lost with this procedure and now I don't know how to get further.
How do I get to the factory recovery screen to try a factory reset again? I tried all types of boot ups (power + vol up or down; power + vol up and down) but none of them worked. As far as I have read a Fastboot cable with the Fire HDX will not help out, too.
I only have access to the file system (Android File Manager) but nothing more, at least what I know. Is there a way to upload a .bin Firmware-File and let the HDX execute it during boot-up? Or how can I make a factory reset? Is there a special code I do not know?
Now the HDX stucks at the "login page" with the blinking screen as described above. I assume it is a problem with the launcher because when I press the power button it asks if I want to shutdown and it is possible to shutdown the device. So the software itself seems to be working.

Unfortunately, You are in FireOS/HDX hell. Borked FireOS w/no adb access. Not much you can do. Even if you were able to access stock recovery a "factory reset" only erases the cache and data partitions. That's not where the problem resides. There is no mechanism on HDX devices to reset or reload FireOS. A huge oversight by Amazon that was addressed in 5th gen devices. But that doesn't help here ...
A bit more history. For several years this condition shelved/landfilled many a 3rd gen HDX. Eventually 'bulk mode' was discovered that permitted reloading the bootloader and/or rewriting the system partition in preparation for installation of a custom ROM. While it may be possible to place your device in 'bulk' mode there is no path forward from there. No one has extracted a replacement/vulnerable bootloader for Saturn not to mention the other items that would be needed for recovery. 4th gen devices are fairly rare with virtually no XDA support and development.
You can try to swipe down from the blank blinking screen with the goal of accessing settings. That might provide a path to re-enabling ADB. Beyond that you probably own an expensive paperweight.
Ok, thank you for your statement. Unfortunately I expected such an answer...

Kindle Fire HDX7

I hope this is the correct place for tis question....
I have received a Kindle Fire HDX 7 which is working- after a fashion. I can install and use various apps, although some system apps, such as ES File Explorer will not open. However when I switch on, the Kindle logo is all white and when I hold the power button and Volume Up button to try and enter recovery, nothing happens the Kindle logo remains on the screen. If I try to factory reset, nothing happens. When I go into fastboot, using my Android Studio SDK folder from my windows 10 laptop, either I get nothing or I get “Waiting for Device” and have to switch off the Kindle and reboot. When I go to Settings – About Phone, it tells me I have a Nexus HDX7, Build number Thor Nexus ROM v2.0.5 @ggow running Android version 4.2.2. I have downloaded the stock firmware for the Kindle (13.4.5.5_user_455004220.bin) but am completely unable to install it and restore the Kindle. Can anyone please help? Many thanks.
