It is going to depend on why you lost boot. This really only applies to those that forced their device into Fastboot mode, particularly anyone that used a Factory Fastboot cable, when you have a condition where the device will not turn back on. It times out of QHSUSB_BULK mode & then is reset by a long hold power condition.

If you made changes to certain system files without properly applying permissions, this could also possibly help. If you however, completely removed system files, then I have no idea. I have not tested that yet, though it seems that it may as the HDX does appear to hold a good portion of the raw firmware on-board for some reason I have not been able to completely determine yet.

Those of you that have the previously thought brick that gives you the QHSUSB_BULK device USB install, you are NOT bricked.

you need to let the device sit for a few minutes & then press & hold the power button for several minutes. I have successfully recovered from this state doing this (purposely) numerous times. Be patient. Let your device sit in BULK mode for 5 minutes WITHOUT touching anything. Leave it unplugged & do not press any buttons.

After 5 minutes, press & hold ONLY the power button for approximately 2 minutes. It should boot in approximately 90 second to 2 minutes, after which, immediately release the power button & let the device restart.

This works for me on BOTH HDX 7 & 8.9 devices without fail.

I'll try this when I get home, thanks!

There is no software. That is a QC diagnostic mode that sits between DLOAD & the bootloader. It may be possible to trigger DLOAD from this mode, however, currently, I do not know if the appropriate driver is available, nor do I know any of the commands that may be used to trigger DLOAD. Likely, since fastboot does not recognize commands, there is a security element that requires a password/key to be sent before, or with any fastboot or DLOAD commands.

I did however reply in YOUR thread & have yet to see any response. I am not sure what you mean by "all white". Are you saying your device powers on, but will not fully boot? If this is the case, you may be able to use ADB to push the system folder, after remounting the partition as R/W, which should restore the files you removed.

This is only for devices that are stuck in QC HSUSB_BULK mode. If your device bootloops, then it is NOT in this mode. What did you do to it? I need info, concise info on what you did, so I can MAYBE tell you how to start going at recovering it. Also, is it 7" or 8.9"?
