Please be patient as I work on completing this guide, as I work full time and am a full time student.
You can find the original discussion thread for this topic here!
DISCLAIMER: I am not responsible for any damage to yourself, your Kindle, or other property incurred by following any or all parts of this guide. Proceed at your own risk.
WARNING: Do not attempt to follow this guide unless you are fairly familiar with soldering and Linux commands. Serious harm to yourself, your Kindle, and/or your computer can result if you are not careful.
Q. What devices will this work on?
A. This how-to works for the Kindle Fire 2 only. (There are other methods of restoring a bricked original Kindle Fire; refer to the FAQ for that device)
Q. Why won't this work for KFHD7"/8.9"?
A. The motherboard designs for the KFHDs are different. That means that the entire process of finding all the solder points for those motherboards (including desoldering the e-MMC) has to be repeated before the same method for fixing hard-bricks on them can be used. (Note: If you have a hard-bricked or otherwise broken KFHD7"/8.9" that you'd be willing to donate for this endeavor, please PM me)
Q. Under what circumstance does will this guide help?
A. This guide is intended to restore the KF2 that was previously thought to be beyond restoring, or hard-bricked, as a result of flashing the incorrect image to your ROM. This means a KF2 that does not display anything on the screen and does not light up the power LED when the power button is pressed (i.e. it appears dead even after charging). If your KF2 still shows signs of life but is not working, please try one of the other methods of repairing it. Might I suggest Q16-23 of the FAQ?
Q. Is there any way to do this without all the soldering?
A. At this time, no; however, I am in the process of developing a device to do this that does not require soldering.
Q. I don't feel comfortable doing this myself. Can I have you fix it for me?
A. Send me a PM and we'll work out the details.
Hard-bricked Kindle Fire 2Suggested materials:
USB SD card reader (one with only one slot, NOT the multi-card readers)*
30 AWG wire (I found mine at Radioshack)
solder (the smaller the diameter, the better)
soldering iron (pencil iron will work, but soldering station is better)
plastic opening tools
a small Phillips screwdriver (mine came with my plastic opening tool kit)
a computer with Linux (a live CD of a distro should theoretically work, but I used an installed copy of Ubuntu 13.04)
*For cheap card readers near me (literally three blocks up the road), I found this one from Microcenter and this one from Tigerdirect. Go with whatever is cheapest for you.
Helping hands tool
A good light source
Magnifying glass/magnifying visor (I used a x7 magnifying glass with built-in light)
Desoldering pump/wick (in case you mess something up, need to desolder the SD card reader, or want to clean up your board after you're done)
Lots of patience
