Amazon Kindle Fire 5.3.1 Hacked – Rooted and new Rom

I just purchased a Amazon 5th gen kindle fire to use as a ground station for my drones. The device supports OTG and has the power needed to run the 3dr usb telemetry device.

Out of the box the fire is kind of useless for anything but an e-reader amazon buying tool.  Rooting and a ROM upgrade solves this! It is fairly simple, however the process is time consuming with lots of waiting (have something else to do like a book or a movie while you’re waiting on certain processes).

Step 1: Make sure you have 5.3.1.0 fire OS installed on device
Go to Settings -> Device Options -> Software Updates to check the version. My device shipped with 5.3.1.0 so I did not need to load a different firmware. Your mileage may vary.

If version is less than 5.3.1.0 follow This Guide instead.

If version is greater than 5.3.1.0 follow these instructions to install the 5.3.1 firmware. download from here

DO NOT attempt to downgrade a > 5.3.1.0 device below 5.3.1.0!!! This it will BRICK your fire.

Once version is 5.3.1.0 go to step 2

Step 2: Reset to factory settings
Go to Settings -> Factory Reset and perform a factory reset. This will reboot the device.

When device boots skip all set up and do not connect to WiFi yet (this will slow down any unwanted update process).

Step 3: Enable Developer Mode
Go to Settings -> Device Options and tap the build number seven times to enable dev mode.
Go to Settings -> Device Options -> Developer and turn on USB debugging and ADB.

Step 4: Download needed files
Download the latest SuperTool from RootJunky and extract somewhere you will remember.

Download the latest Nexus ROM for Fire Tablet but DO NOT extract it.

Step 5: Run SuperTool
From a command line navigate to the SuperTool folder and run the appropriate file. In Linux the command is
$ ./3-Amazon-Fire-5th-gen-linux-mac.sh
You will see a screen like this:

Press 2 and Enter to root device. First it will install KingRoot to your device which you will then have to run from your device when directed to do so. KingRoot will ask you to connect to WiFi.

You will likely have to run KingRoot repeatedly before it will work. Time to grab a book or a movie as this part takes time. Each time you run KingRoot it will reboot your device a few times and show progress on the screen. Each attempt takes about 10-15 minutes or more. After the first attempt I unplugged my device from the computer and had to run KingRoot a total of 4 times before it worked. Just keep trying.

Once root is gained plug your Fire back into the computer (you may need to cycle the ADB setting on your device for it to be recognized) and continue the SuperTool process following all instructions there. This will install SuperSu which will need interaction from you on the device. Follow the setup procedure according to the instructions in SuperTool.

Once this process is done run “Block OTA updates” to prevent accidentally losing root access.

Step 6: Install Rom via FlashFire
While still in SuperTool install FlashFire (option 6).

From your computer copy the zipped ROM file downloaded in Step 4 over to the INTERNAL storage of your Fire device.

On your device run FlashFire and follow these steps exactly, otherwise you risk the installation having problems:

Select the red plus (+) button to expand a selection of options, choosing Wipe.
Select System data, 3rd party apps, and Dalvik cache if they are not already checked.
Click the red plus (+) button again and choose Flash ZIP/OTA.
Search for the Nexus ROM that you’ve copied over and choose it.
Automount and Mount /system read/write need to be unchecked.
Drag Wipe to the top of the queue.

Hit the flash button to start the process.

This will take a few minutes and the screen might go blank for a while. It will eventually boot into the new ROM.

Step 7: Enjoy!
With new ROM installed be sure to update Google first. After it updates clear google app and framework cache and reboot.

Install apps. You will need EVERYTHING as this is a very vanilla ROM.

OTG works great with APM/Tower or DroidPlanner software.

Much faster, full play store support and NO ADS! Yay!

Configure Tarot 2D Gimbal on Linux / Wine

Having trouble getting serial devices in Linux to show up as COM ports ( eg, COM1 ) in Wine? So was I. Getting the correct software to configure your Tarot Gimbal and getting the com ports to work can be a nightmare.

Problem solved! Read on!

So you have a Tarot Gimbal and the included USB programming dongle.

On your *nix machine ( I am using Ubuntu, your mileage may vary ):

Make sure user has dialout privileges:

$ sudo usermod -a G dialout username

Log out and back in.

Install Wine:

$ sudo apt install wine

Configure wine to run XP

$ winecfg

Add required items to Wine registry (~/.wine/system.reg):

[Hardware\\Devicemap\\Serialcomm] 1231984861
"Serial0"="COM1"

More info here: https://onetransistor.blogspot.com/2015/12/wine-serial-port-linux.html

Plug in your USB to serial adapter to computer. Link device (ttyUSB0 in my case) to Wine com1

$ ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1

Download programming software: ZYX-BMGC-EN_V1.5.zip

Uncompress the file, right click on main application and select run with Wine.

Plug in connector on USB to Gimbal.

Select COM1 in software and click connect.

Power on drone/gimbal.

Hack Away!

Kombucha Recipe

We can all thank the Angelfish for giving me a reason to post this 🙂

The following recipe is for 1 gallon of ‘buch. It can be halved/doubled etc. to match your needs. All cooking times stay the same.

You will need:

Kombucha Brewing
Kombucha Brewing

2 quart pot
1 gallon of good water
1 cup sugar, organic unrefined preferred
1 SCOBY (AKA the Mother… a Symbiotic Colony Of Bacteria and Yeast)
1 cup starter tea
8 oolong, green or black tea bags
1 g glass jar. NO METAL!
1 piece of cotton cloth or paper towel. Holes in cheesecloth are too large, if using cheesecloth use at least 3 layers.
1 rubber band

Procedure:
Clean hands and all utensils with distilled vinegar after washing with NON-Antibacterial Soap.
Bring 4 cups of water and sugar to a boil.
Once boiling add the teabags, count to ten, then remove the pot from heat source.
Put the lid on the pot (leaving tea bags in) and wait for 5 mintues.
After 5 minutes remove the lid and add some water to fill up the pot.
Wait 5 more minutes.

SCOBY Farm!
SCOBY Farm!

Remove tea bags and squeeze them out. Let this “sweet-tea” sit and cool off for at least 20 minutes. Ideally temp should be below 110 degrees Fahrenheit before continuing.
Put SCOBY and starter tea in brewing jar. Pour sweet-tea into jar. Fill remaining space with water up to 1.5-2 inches from top of jar. Stir with WOODEN or PLASTIC spoon.
Cover jar with cloth and secure cloth with rubber band. Put jar in cool dark place (pantry or cupboard). Do not disturb jar while fermenting.

In a few days a new SCOBY will start to form on the top of the tea. After about a week start tasting your brew using a wooden or plastic spoon. When you like the flavor, you are done! Bottle it up and enjoy. Google for more recipes and flavoring ideas.

Baby SCOBYs
I got SCOBYs, who wants one???

NOTES:
Never expose SCOBY or ‘butch to direct sunlight.
Never expose brew to any type of metal.
When you first start brewing, there will be more yeast than usual.

It’s brown and gross looking. This is normal. Unless your SCOBY is super fuzzy everything is probably normal. As your SCOBY adjusts to it’s new environment it will get whiter and produce less yeast strands.
After brewing is finished, the new SCOBY can be separated from the old to start a new batch, make additional batches, give to a friend, make bio-pleather, etc.

After the first harvest, bottle all but a cup or two of the brew and just pour some new sweet tea in the jar and brew it.
