[Kindle Fire Q&A, Help & Troubleshooting] s2p2e:
SOLVED Thank you so much, "Thepooch"!

We finally got fastboot to recognize it in Linux by plugging, unplugging regular and factory cables, with battery in and out. From there, we flashed twrp and fff, and she booted up! problem was, it would only boot with the stock charger and the battery unplugged. Looks like the battery got fried somewhere along the way. So, I took my battery out of my kindle, put it in his... And all's well now! I have a replacement battery shipping to put in mine. Thanks again, Thepooch! We saved it.

I really didn't want to start this thread. I was determined to keep searching the forums, keep re-installing the drivers, to find a way to get this thing back up and running without just giving up and coming to you guys so that you have one more clueless idiot to take care of. But I'm out of ideas. I don't know where else to search, what else to read.

I had no issues rooting my own Kindle in December of last year, so when a friend wanted help with his, I thought it would be just as easy as it had been the first time. His device was on 6.3.1, however, and kfu didn't work. The device rebooted and has been stuck at the static Kindle fire (white and orange) logo ever since. That was over a month ago, and I'm at the point of desperation. We're both going off to college soon and he needs his Kindle back (I tried to give him mine, but it's not in the best condition - screen's cracked - and he wants his fixed or a new one).

I've read the Kindle Fire guide for beginners countless times, along with every thread regarding being stuck in fastboot; I know the issue lies with my drivers, but I don't know how to get out of the situation I'm in. The device shows up in Device Manager as unknown, and when I manually install the drivers, I get code 10. Uninstalling drivers, restarting the computer and Kindle has done nothing. I've even resorted to using the firekit, hoping to bypass all of the hassle of dealing with Windows drivers, but the Kindle is never recognized (waiting for device) when I try normal_boot or the command for installing twrp and fff. I've tried two different computers, both 32 bit windows 7 devices. I tried the firekit on both as well, same results. I've tried going through with the commands, despite the code 10 error of the device not starting (navigate to kfu/tools, open cmd prompt, fastboot -i 0x1949 getvar product, hard reset, turn kindle back on, unplug and plug back in, nothing makes Fastboot recognize it). There was a point where it showed up as kindle! in the device manager, but installing the drivers ended up with the same code 10. Now it's just unknown device, or Android ADB interface with code 10, once the drivers are manually installed. I've tried the Usb commands in the Firekit with the shorting trick, but no success there, either.

Have I missed something that will save me, despite the hours, no, days of searching? I don't know what else to try and any sort of help anyone could offer would mean the world to me. If there's someone that can help me through this, I'm willing to reward you, but I do not have the money to replace my friend's kindle. The one I got last year was a prize in a contest I won.

Please, help? Is there any other information I need to give out? :confused:

I really appreciate everything you guys do here, and I know you don't get thanked enough for all of the time and effort you put into helping people out when you don't have to. I love to help out and I'm trying when I can, but I feel like I shouldn't be giving too much advice when I can't even get this Kindle to work.
