It describes how to do it if update from sd-card and update over usb fully works.

In this post, however, I will describe how to cope when both options do not work (the system does not recognize UPDATE.APP or update over usb does not work, or - after updating- tablet still continues to bootloop).

Ok, let`s start. Warning!!! It will be difficult and cost of money :/​

Needed tools:

ADB & FASTBOOT

Additional drivers

DC-Phoenix(PAID!!) {Mod edit: Link to paid software removed. Oswald Boelcke, Senior Moderator} or Huawei-Update-MultiLoader-Tool (FREE!!! :)) {Mod edit: Link to Easy Firmware removed. Oswald Boelcke, Senior Moderator}

EF-tools from ... to login into site.

Pendrive with at least 4GB freespace and OTG USB cable or SD-CARD.

We gonna also need board software(paid) :( And full software assined to our device. Thank`s good`s not all is paid :D:D:D

This software - among other things - allows updating via SD-CARD and OTG cable. Unfortunately, it's Chinese.

Uff!!! :)

How to flash Board Software with DC-PHOENIX?​

First: battery at least 70% charged (for safety), but it would be best if it was 100%.

Download and install firmware and drivers for you device.

Buy a credits for DC-Phoenix, witch allow you to doing flash.

Download board software from ... site

Turn phone into fastboot/bootloader mode (powerdown device with long-pressed power key, push VOL- button and connect tablet to PC).

Open DC-Phoenix.

After opening u will see a login window.

Enter the username and password, then log in to the server.

After login, u will see window with information, where u can get a tutorial to flash.

Regardless of what you press (yes or no), the program will guide you to main window.

On the right side u may choose update file and customisation file (usually main update file is in root of "dload" folder, and customisation file is in folder inside dload, but in case of "board software" the path-to-file ,after unpacking will be look something like that ~\KOB-L09C500B007\KOB-L09C500B007_降级包 ). In "Update firmware" tab we have two options: standard and advanced. Choose first one, and next in field "Update file" navigate to downloaded board software UPDATE.APP file. File will be loaded, and program will show you list of partitions to flash. Then press update button and wait for process to be end.

Tablet will be flashed with board software and reboot.

It may take a while to start. Do not turn off your tablet under any circumstances. This can result in a hard-to-repair software damage (hardbrick) what can result in the need to return the device to a specialist service. !!!​

Well, we've received a tablet with the basic version of Android installed, with several test applications.

We do not need them.

How to flash Board Software with Huawei-Update-MultiLoader-Tool ​

Download Huawei-Update-MultiLoader-Tool.

Unpack and open it.

Select an UPDATE.APP file.

In next box select Android-Phone-Multi-Upgrade-Config-PCUI.xml file.

Click "Next", and wait until files will be loaded.

You will see another window.

Press together VOL+ and VOL-, then plug your USB cable and connetc device to PC.

Program will recognize device, else click "Scan" button in top of window.

Wait :)

Prepairng SD-CARD or USB drive ​

Copy the "dload" folder from the software appropriate for your device to the usb disk or sd-card. Then connect it with an OTG cable to the tablet or plug sd-card to device. Press and hold the power vol up and vol down buttons. The software update screen will appear, and update will start. When finished, the device will restart and you should enjoy "rescued" equipment. Another way is to boot in installed "Board" system, and select "SD upgrade" icon.

Unfortunately, I can not provide board software files because of the ownership rights.
