It was just for fun, and this would be a good exercise for potential migrating my AT&T phone to some other images – I need hotspot feature but it’s a premium feature from AT&T …

Back to Kindle Fire, the process was pretty simple – root it, flash with new root image and gapp, that’s it. However, after that it seems some Apps are not that stable, crash or slow respond from time to time, though some other Apps run smoothly. I’m not sure so far if it is problem from Apps (i.e. compatibility issue with Jelly Bean), or it is Jelly Bean I was using is having problem with Kindle Fire (incompatible or poor hardware). I will play with them for a while and post here if I see anything interesting.

Refer to Recover a bricked MK802III for requirements, plus you need a micro SD to transfer the update file

  1. Download the zip file from here
  2. Unzip the zip file, you will see “update.zip”, copy it to micro SD
  3. Move the micro SD from your computer to MK802III, it will automatically recognize the update image.
  4. Follow instructions on the screen to finish the upgrade, this will take 3~5 minutes and the stick will reboot couple of times

What you need:

  1. Macbook Pro + Virtual Box + Windows XP VM
    Alright, I’m kidding โ€ฆ you just need a Windows machine, I tried Windows 7 and Windows 8 (using Windows 7 drivers) are both working, but in case you just have a Mac like me, VM is the way to go. You’d better map all USB devices to the Windows VM since it changes name during regular boot+USB debugging, and recovery boot.
  2. Download the recovery kit from here, use the MK802III link, you will get a zip file. Unzip, launch RKBatchTool.exe and leave it running on your Windows machine.
  3. Unplug everything from MK802III, open the case of MK802III – nail is the best tool for me and it should work for you as well
  4. Follow the document (one in English and one in Chinese) to short circuit the two pins, and plug in the USB to your computer at the same time. I actually found there are two small dot beside the other side of the chip which is more easier if you have a flat metal piece instead of a tiny needle.
  5. If everything works smoothly, you will see one block in the RKBatchTool.exe interface changed to some other color (different color may have different meaning, but I really want to ignore it for now).
  6. Click the button with “โ€ฆ” on the top right corner of the RKBatchTool.exe interface, pick the img file from the zip archive (should be RKM802III_20121115Recovery.img), click “Upgrade” button (that’s the 2nd button from left, at the bottom of the interface), it will take 2~3 minutes.
  7. Power off/on the MK802III, you will get original official Android back running on the stick.
