Disconnecting USB while the first upgrade for the Firmware KDlinks A400M

[VACUUM]

How to fix the TV-Box problem?


Hello
I have a kdlinks A400M Android Media Player . I  tried to upgrade its firmware which was based on the Android 5.It was unable to boot showing kdlinks logo.
I tried to install the zip file: #1 Build number HMD-2.0.6 2017-11-05.11415 which is
provided on the official website of Kdlinks, first.

What I did was based on these:

1. Copy update.zip to the root of a USB pen drive (so the USB pen drive should contain a single file named update.zip).

2. Insert the USB pen drive into any USB port of the KdLinks A400.

3. With the A400 4K3D turned off, use a paper clip or pen to press and hold the the pinhole restore button on the back of the KdLinks A400.

4. While keeping the restore button pressed, turn on the KdLinks A400.

5. Keep the restore button pressed until you see an Android droid logo.

6. Release the button and the firmware upgrade will proceed.

which is recomended on the official web site of kdlinks.
But My bad during the update due to a problem I had to disconnect the USB.
Now I am trying to reinstall the upgrade zip file after doing a
FAT32 computer reformatting  for the USB and pressing the "UPGRADE" button on
the rear of the unit again,but there is no
reaction from the kdlinks.
what do I do?Should I wipe anything?How?
please help me.

Many thanks

I am not familiar with KDlinks products although I appreciate that they are based on HiMedia Q10 Pro.

For HiMedia Q10 Pro the correct update procedure to Android 7 would be to install version 2.0.4 first (https://www.mediafire.com/file/bzd7e7vi9bbwz6a/Q10_PRO_FIRMWARE._ANDROID_5.1_TO_ANDROID_7_v2.0.4._FUTEKO._HMD-2.0.4_2017-07-05.191425.zip/file) then update to latest Android 7 firmware. This may be different for KDlinks though.

If you removed the USB stick during install it's possible the box is bricked and there is no alternative flash process for Q10 Pro so it's impossible to recover from.

My general advice is to contact KDlinks. They will have better information about their own product.
