Appears you made several key errors any one of which could have bricked your device. If you are successful in making repairs (replacing mother/daughter boards) check back before making another run at installing a custom rom. Suggest posting a brief synopsis of steps planned before taking action.

Amazing Work!

finally after about 1 and a half years i was able to unbrick my device.

Thank you so much! :)
[Kindle Fire HDX 7" & 8.9" General] adeba:
hello,

i have a bricked hdx7 thor. i run cm11 with safestrap but i dont know what fire os version. could it be 1314.3.4.2. is there a way to find it out? the device stands with screen "kindle", no boot loop or green screen. when i put it on a windows 7 pc, the device manager shows "android" device. but i havenz install any drivers. must i install the fire hdx7 windows 7 drivers? whats the next step, install adb?

edit: its some month ago the brick. i disable ota, install safestrap and the cm 11 imgage. it works everything. but then i make a mistake and erase the fire os partition.

thx

hello. with greylogo with firmware >3.2.6 - no options.

if firmware < 3.2.6 - use this method.
[Kindle Fire HDX 7" & 8.9" General] adeba:
what exact mean greylogo? an grey kindle logo? i have a yellow kindle logo.

must i install the kindle fire hdx7 adb drivers before?
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
This thread for hardbricked devices with firmware <3.2.6

your device is bootlooping with probably higher sw version.

install adb , check for root - if you have it - ask in Q'A section for your next step

if you doesn't have root - you could try this method as described.

if you will get error openning port - you sw version is higher and no option to recovery.
[Kindle Fire HDX 7" & 8.9" General] adeba:
thanks, but its no loop, it stands all the time kindle without reboot. or does this failure also called loop?
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
Ok. i see - your device stuck on loading but no any sense to clarify terms/

First of all check adb access.
[Kindle Fire HDX 7" & 8.9" General] DB126:
If you installed Safestrap v4 w/CM11 then your device was running some version of FireOS v4 which can not be unbricked using this method.
[Kindle Fire HDX 7" & 8.9" General] adeba:
ok, is there any other way to unbrick?
[Kindle Fire HDX 7" & 8.9" General] adeba:
Update : i installed safestrap 3.75 an a custom 4.22 rom. then i wiped everything, included system. now it hangs in boot with grey kindle screen. reset factory defaults does not help.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Not that I am aware of. This method described in this tread is probably your best option. Kindles in general and HDX models in particular are crippled with a locked bootloader. You could try unlocking with this tool but the underlying prerequisites must be met (last FireOS install <= v3.2.3.2). There's an outside chance given you were running Safestrap 3.75 which is normally installed on devices running FireOS v3.
[Kindle Fire HDX 7" & 8.9" General] adeba:
hello,

when i put it on pc, is says unknown usb device and not qhusb_bulk, what can i do? the bootloader was not unlocked, must he?

edit: must the hdx stand when i try adb in grey screen? or in the menue for factory default?
[Kindle Fire HDX 7" & 8.9" General] -Tofu-:
Did the same thing. Device is at the same state. :P
[Kindle Fire HDX 7" & 8.9" General] adeba:
hello,

i have an hdx7 with grey logo. i installed windows new. then i install the kindle fire adb drivers. at next i install minimal adp and fastboot. when i put it on my laptop the device manager says "MTP-USB Device". When i wait some seconds, in the device manager comes a exclamation mark in front of the device.

when i am in adb tool directory, and type adb devices -l (is that ok?) there are no devices. factory in boot menu from kindle also the same.

can someone help me? i have also no problem when somebody looks via teamviever.
[Kindle Fire HDX 7" & 8.9" General] player594:
I have the same problem. Started using this program but device came unconnected during install, now it shows as unrecognized. At a lost for what to do. Iirc it did this once before. Showed as unrecognized then later on when I plugged it back in it was back to bulk.
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
Hold power button until device will reboot into bulk-mode. Sometimes it takes above 5 min.

If no luck - try to use other usb ports or other PC or other cable.
[Kindle Fire HDX 7" & 8.9" General] neoroid:
Stuck on opening Serial port (no progress) anyone know if there is a way to solve this, my tablet was rooted and I've installed CM12 on it before it got bricked... so I don't know if the version of FireOS that was installed before have something to do but I guess yes since it's in the boot part (still I hope that someone help us getting the required files to reconstruct the whole boot or flash completly the eMMC with a full image...)

I hope there is a chance to do it... because even the option to access the eMMC directly from the motherboard via wires soldering (fortunatly some guys found a way to do it) we still lack the required files to fix this... and it's turning to be a nightmare all the confusion around the files to get from here and there
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
This method is not suitable for your firmware.

Your option is replace motherboard or ivannik's hardware hack (pls do not post here duscussions about it).
[Kindle Fire HDX 7" & 8.9" General] DB126:
If you were actually running CM12 on this device then the bootloader was unlocked which means FireOS was rolled back to xx.3.1.0-xx.2.3.2 and thus eligible for this unbrick method. If you bricked the device trying to flash CM12 when the prerequisites weren't met then all bets are off.

It is unlikely anyone is going to research the components required to reconstruct to boot sequence or fire out how to reimage via direct access to the eMMC. Device is discontinued; people are moving on. The HDX line was always a ***** to work with; unrecoverable bricks are the frequent outcome of an experiment gone bad. Kinda ruins your day given the high cost of these pups.
[Kindle Fire HDX 7" & 8.9" General] neoroid:
Thanks for the details, this tablet was collecting dust since a very long period to the point I even forgot what version of firmware is in there (I was enjoying modding it from FireOS and all went like a charm, until it got hardbricked for a reason that I still ignore but I think I've tried to install boostrap or FFF went to sleep and in the morning I found a dead tablet, I recovered it before from softbrick but this one I don't have Fastboot nor ADB... just dead!)

I was hopping that someone find a solution but so far nothing work...

I found a new version of MiPhone just in case someone want it (20151028) http://bigota.d.miui.com/tools/MiPhone20151028.exe

I still hope that someone find a solution ( I tried myself all kind of experiements but failed) as I loved how fast this tablet is and unfortunately I didn't even enjoy it and I cannot afford a new one right now... the technology is progressing so fast nowadays that as you said people are moving on faster and faster...
[Kindle Fire HDX 7" & 8.9" General] player594:
OK holding the power button for a long time does cause the connection to reset, but Windows isn't registering anything now. Funny thing is MiFlash shows a device in Com10 that wasn't there before. Trying to flash causes the program to stop with catastrophic error. Tried different cables too. Anymore ideas??
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
Other usb ports, pc. Check drivers. If miflash shows comport - you should see bulk at device manager.
[Kindle Fire HDX 7" & 8.9" General] player594:
OK now it says "Reached the end of the file(0x80070026: Receiving hello packet) missed hello packet
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
Attach full log, pls.
[Kindle Fire HDX 7" & 8.9" General] player594:
Where do I get the log?
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
Read OP. "Logs of flasher..."
[Kindle Fire HDX 7" & 8.9" General] ONYXis:

Recommendations still same - check drivers. Try other PC.

Show your device manager with this bulk.

Did you use Miflash from my archive?disabled signature check if your OS is x64?
[Kindle Fire HDX 7" & 8.9" General] player594:
OK I have tried everything you asked. Different computer, Windows 7, new cable, driver is listed on COM port 10 as Qualcomm HS-USB QDLoader 9008 (COM10). Still doing the same thing. After missing "Hello packet" it stays on Open Serial Port "\\COM10" for a long time then "Reached the end of the file (0x80070026: Receiving hello packet) shows up in red type.

[Kindle Fire HDX 7" & 8.9" General] ONYXis:
Ok. At this time it works. But seems your kindle firmware >3.2.6.

Ps. I read your previous posts. You did rollback, this method doesnt work for situation like this.

Your option is change by warranty or change motherboard.
[Kindle Fire HDX 7" & 8.9" General] player594:
Ok thanks for trying to help. I got it rolled back successfully but it tried to OTA uodate and thats when it went haywire. Too bad there isnt a way to wipe and write everything back. Oh well. Like I said, thanks

I use Qualcomm Flash Image Loader (QFIL) 1.0.0.2

I don't know how to put my kindle fire hdx 8.9 3rd gen into Firehose mode

I use fastboot usb cable to boot the device into fastboot mode
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
Pls, read OP and follow instructions.

1. Install qualcomm drivers. This is main problem.

2. Use miflash (my version!!!), to examine logs at least.

3. Qdloader (with wrong drivers from Windows Update) from your screenshot - firehose proto. Fastboot cable can't boot this generation of tablet into fastboot.

the one that came with the fire hdx is just a normal one right?

i do have a moto g 2014 is that a fastboot cable? i have to search for it ;)

"kindle fire fastboot cable" from ebay OK

i bricked my kindle apollo (hdx8.9 3rd gen) a year ago. i can't believe i was able to un-brick it a few days ago. i just wanted to share a few key points of my experience:

(1) my apollo was stuck in the gray "kindle fire" logo. i could get into the stock recovery (power+vol up) but factory reset did NOT fix anything.

(2) i bought a kindle fire factory cable from ebay that said the cable will NOT be compatible with "kindle fire 8.9". i thought a fastboot cable is a fastboot cable. there is not much one can do with a usb cable. cable got to NJ fast from china.

(3) at first the cable seemed not working as i did not see anything happening on the apollo screen. a black screen was all i got. also, i did not see a new usb device under linux using lsusb.

(4) it was good that i did not give up and tried using a different usb port. bam i saw a qualcomm usb device.

(5) to recap, try using different usb port or computer. also don't expect to see anything on the apollo screen. finally you may need to press the power button for a very long time to see the device showing up. i used a clip to hold the power button down until i saw something showing up on the computer.

(6) i used windows7 x64 to run miflash. the driver installed automatically. the tricky thing here was that i had to try different windows7 computers. the first win7 pc gave me runtime errors when trying to flash. i almost gave up here too. i was glad i tried a different win7 pc (a newer one). the 2nd win7 pc worked.

(7) yes the 2nd win7 pc worked but i forgot to replace the thor recovery.img with the apollo one. i found that out when i tried to enter the twrp recovery after the flash. lucky all i needed to do was to reflash one more time with the apollo recovery. i was then able to see the twrp recovery screen.

(8) when in twrp recovery mode, i was able to use adb under linux to talk to the apollo. adb shell also worked in this mode. if i was not in twrp recovery mode, i saw a dark screen. in that mode, i could talk to the apollo using fastboot under linux.

(9) once i had twrp recovery, the rest was quite straight forward.

i am immensely grateful to the guys who put the files and tools together to allow me to un-brick my expensive paperweight. THANK YOU ALL.

[Kindle Fire HDX 7" & 8.9" General] DB126:
Sounds like in incompatible TWRP image. Use one of these (must match your model); you can update to 3.x later if desired.

I was able to get the touchscreen drivers installed and get TWRP working again. I grabbed the stock image files from the thread below and flashed. Everything seemed to go just fine, but when I reboot I just get a black screen. No Kindle screen. It just sits on the black screen. Any ideas on why it won't boot using a stock image?

http://xdaforums.com/kindle-fire-hdx/development/twrp-flashable-stock-images-t3194914

Edit: Nevermind. I got everything working again by flashing a 3.2.5 firmware from the OP. I missed that step.
[Kindle Fire HDX 7" & 8.9" General] Maverick777:
I have a new, but less serious problem now. I'm on the 3.2.5 firmware and want to upgrade to 4.5.5.1. I downloaded the firmware and transferred it to the Kindle via USB. The Kindle picked up the file in the update settings, validated it, then powered off to install. It then gets stuck at the gray "Kindle" screen.

Any ideas why it won't update properly?
[Kindle Fire HDX 7" & 8.9" General] ONYXis:
Try to hold power button. I think you stuck entering to stock recovery. It is corrupted.

But why you are doing this? what purpose? if you wanna stock - why you dont try to upgrade to latest 4.5.5.2 ?

Or why dont use repacked stock?

Anyway if I am right, I think you need to restore any recovery at this moment.

So need to again use this method but to avoid any problem replace recovery.img and emmc_appsboot.mbn with these (rename twrp and aboot_vuln). I need to fix this manual.

sure. your firmware is > x.3.2.6 and this method not suitable.
[Kindle Fire HDX 7" & 8.9" General] DB126:
- if the device once hosted CM 11/12.1 the bootloader version is >3.26 it can not be 'unbricked' using this method

- bootloader can not be unlocked without a functioning ROM to obtain device specific information needed to generate an unlock code

- it is very unlikely your device can ever be recovered without replacing boards

Will this help with only a Blank Screen?

Hey all I was using a bootloader unlock and I hosed it (to make a long story short I didn't disable drivers signature verification) up now all my kindle does is display a blank screen. No "kindle" grey logo or bootlooping, just a blank screen, I got a fastboot cable but still no luck with my Windows 10 machine being able to recognize/see my kindle. My question is: is there any hope for my kindle ever working again? Do I just need to hold the power button down for 5 mins (I saw that suggested)? I also have a linux box is there any software that would work with Ubuntu? Any answers are greatly appreciated.

Thanks,

Two Crows Seeing
[Kindle Fire HDX 7" & 8.9" General] DB126:
- fastboot/factory cables are useless on this device (with one exception as outlined in the OP)

- unlocking the bootloader does not expose the device to a brick risk; something else happened

- this thread and the techniques outlined in the OP are your best hope depending if you successfully flashed a vunerable bootloader prior to the device going no responsive

- otherwise...it is highly unlikely the device can be salvaged short of board replacement
[Kindle Fire HDX 7" & 8.9" General] player594:
Sounds like your in the same boat as me. Mine powers on to black screen only. Connecting to pc gets it detected but that's it. Can't recover anything.
[Kindle Fire HDX 7" & 8.9" General] DB126:
Were you attempting to unlock the bootloader around the time of failure or did the device die for some other (known/unknown) reason?
[Kindle Fire HDX 7" & 8.9" General] player594:
I rolled back the firmware so I could root but forgot to turn off auto update so it tried and bricked my tablet. Now it is a paperweight

Sometimes it shows up up in MiFlash and if I choose to flash it gets hung up on waiting for Hello.packet.
