Each kindle needs its own set of libusb-win32 device drivers installed, to work with fastboot for windows. There are multiple ways to do this, and multiple versions of libusb drivers for windows.

You can read some details about how *I* installed them for my K4 and Touch here:

You still need to know which libusb-win32 version, and what installers to use, and more (that you can learn from the libusb websites). More information will be provided later (perhaps in a wiki page). Hopefully there is enough information at the above links for you to figure out how to use it now if you need it.

This eliminates the problem of needed Windows for MfgTool and linux for fastboot, and the problem of the kindle dropping out of fastboot mode when the USB connections is disconnected or reset (by rebooting the host PC or VM). But it has the added complication of needed Windows device drivers.

At least there are alternative methods of using MfgTool and fastboot now, so you can use whichever method works best for you.

Hi man, mi kindle model is touch 3g (the last touch model). I have been reading all the steps from the previous report by Poetcop and trying to repeat but I don't understand some things and terms. I downloaded libusb and get recognized my kindle by windows xp (in virtual box), i copied the same text from .inf that you use geekmaster. I don't understand the next step that runs fastboot.win.public there are some .dos files that can´t work correctly I suppose. Also in the report from Poetcop mentioned that uses Linux, what version recommends to install in mac osx (virtual box) and how I can run ssh file

Oh frabjous day! Caloo calay! My Kindle Touch is unbricked, freed from the black screen of death! I'm so grateful to the friendly wizards on this board, especially hostar and double especially geekmaster. You have achieved amazing things. Let me put down the steps precisely, in case it might help someone:

* First, I installed hostar's windows port of yifan lu's fastboot tool, fastboot_win_alpha. That was the key. The only complicated part was the libusb-win32 installation, but I got through it by following the instructions on the sourceforge page carefully:
http://sourceforge.net/apps/trac/libusb-win32/wiki
geekmaster's screencaps should also help.

* Then I booted into fastboot mode, for the thousandth time, but this time to actually do something. In case you don't know, you hold down the power button until the light goes off, and then, without releasing, press the home button and then release the power button.

* Then I ran the following commands:
fastboot flash diags mmcblk0p2_ssh.img [from the first post in this thread]
fastboot setvar bootmode diags
fastboot reboot
That got me into diags mode, for the first time in weeks, and my heart sang!

* I started ssh, following geekmaster's instructions to "Select menu items N) U) Z) X). Wait 20 seconds for dropbear to startup"

* In linux on my mac os x, entered ssh root@192.168.15.244, with password mario. It complained that the device had a different signature or some such, so I had to delete the line containing 192.168.15.244 from known_hosts, at which point I was able to get in.

* I'd forgotten to copy mmcblk0p1.img to my /mnt/us, and I discovered that the USB mode option in diags didn't work after starting ssh, but on choosing Reboot (D, R from the main menu) it did work again. Then I went back in with ssh.

* dd if=/mnt/us/mmcblk0p1.img of=/dev/mmcblk0p1 bs=4
which took 137.6 seconds.

* Now to reboot into main. Disable Diagnostics didn't work, with the message "device_info.xml not found, check device settings", but no problem with my new fastboot powers, I just chose "Install fastboot bundle" and then ran fastboot setvar bootmode main, fastboot reboot.

* The normal, healthy Kindle reset screen, and the same screens I saw when I first bought it. I wonder if this was affected by me running fastboot setvar bootmode factory at one point. I had to unplug and plug the usb back in to get the normal directory to mount, but when I did unlike when I exported it before, it was populated with the expected folders.

I marked with blackie the steps that I don't understand, and what exactly is the definition of ssh and how to work with linux (which version) to restore my kindle touch. Excuse me for my ignorance, I don´t really know much of system or this process, I beg if can explain in more details some terms and steps to follow. At this moment I only can get the kindle in fasboot mode the same as the images from this post
