KitKat update guide (HKC1 ONLY)

So let me do the tutorial real quick. This is a translation from this tutorial: http://hispatablets.com/teclast-x98/tutorial-para-instalar-kitkat-teclast-x98-hkc1-t1790.html

Requirements:

Teclast X98 3G (HKC1, firmware version 1.11)

Files from here: https://mega.co.nz/#F!UFdilCpK!tNOmz1msDRKu3tF16oFjdQ

MicroUSB cable

Computer with Windows (I've installed it in Windows 8.1, so I guess 7 and 8 should work)

Steps:

1. Installl Drivers

First of all, let's install the necessary files. Install in the following order:

iSocUSB-Driver-Setup

IntelAndroidDrvSetup

ManufacturingFlashToolSetup

Once those three are installed, copy the CUSTOM_CONFIG.INI file in the folder where you've installed Manufacturing Flash Tool. The default path is C:/Program Files[(X86) if you have a 64-bit machine]/Intel/Manufacturing Flash Tool.

Unzip the big firmware file (KK-HKC1.zip) and check for a file called flash.xml.

2. Extracting VID/PID

We open Manufacturing Flash Tool, we click on File-Settings, and the following appears:

We have to input the VID and PID values for our device so MFT recognizes it. We'll have to put it in Flash mode and Droidboot mode so we get the 2 VID and 2 PID values necessary. We get the reading of the VID and PID values from the Device Manager in the following fashion:

2.1 Extract VID and PID from Flash Mode (SOC Devices)

Turn device off

Hold both volume buttons AND the power button until the Teclast logo appears

Connect the tablet with the MicroUSB cable

Once connected, go to Control Panel-Device Manager

Seek the Intel Android Phone category, just over Intel SOC. Expand it and right-click on Android ADB-Interface. Click on Properties

In the Properties Menu, click on the Details tab (third one) and then on the scrollable list. Check Hardware ID.

You'll see two alphanumeric codes, one for VID and the other for PID. Take note of them,

Unplug the USB cable and leave the tablet alone for a bit. It'll turn off on its own.

2.2 Extract VID and PID from Droidboot (Android Devices)

Turn device off

Hold both the Volume+ AND the power button until the Teclast logo appears, and then the Droidboot screen (similar to Fastboot)

Connect the tablet with the MicroUSB cable

Once connected, go to Control Panel-Device Manager

Seek the Intel Android Phone category, just over Intel SOC. Expand it and right-click on Android ADB-Interface. Click on Properties

In the Properties Menu, click on the Details tab (third one) and then on the scrollable list. Check Hardware ID.

You'll see two alphanumeric codes, one for VID and the other for PID. Take note of them,

Unplug the USB cable.

Browse with the volume buttons until you get to the Power Off option. Confirm with the Power button and the tablet will turn off

Once we have the VID and PID values, we input them on the Manufacturing Flash Tool in this specific way:

In my case, the values were:

Soc Devices: VID 8087, PID 0A65

Android Devices: VID 8087, PID 09EF

3. Installing the firmware

Now we have MFT open, so we close the Settings menu with "OK" so the VID/PID values are confirmed. Now the good part comes: installing the firmware. We click on File-Open and we browse for the folder with the unzipped firmware. Look for the flash.xml file and select it,

It's time to put the device on flash mode. With the device turned off, we hold both volume buttons and the power button until the Teclast logo appears. Connect the tablet right after that and let it be. As you see from my log, the flashing takes at least 8 minutes, so be patient and FOR THE LOVE OF ALL WHAT'S HOLY DON'T DISCONNECT THE TABLET WHILE IT'S FLASHING. It'll do everything on its own, including the reboot.

4. Fixing the audio

If we stop there, we'll notice quickly that there's no sound input (mic won't work) or output (no sounds come from the speakers). We need to inject a couple of files.

Download Audio_Update.zip and unzip it

Turn on the tablet and activate ADB debugging mode in the settings

Open the folder where you've unzipped it and open a shell (command window)

Plug the tablet to your computer

Run the following commands:

[B]adb devices[/B]
[this is so we check that the tablet is correctly seen by the computer, it should say "BayTrail something"]
[B]fpt-setup.bat[/B]
[ignore the error that comes out]
[B]update.bat[/B]

Once you've ran the three you'll be prompted to press a key. The tablet will be rebooted and you'll get to say "OK Google" in peace.

And that's it. Enjoy the chucklet!

Thanks have to be given to leroys who provided the firmware. Also dukito from HispaTablets provided the driver files that I link in the Mega folder. I hope you enjoy it, Remember that no success is guaranteed and that

any result is your and only your responsibility

. Which is fine.
