Then you had v1.25 or v1.26. I gonna suggest downloading the v1.25 firmware zip file from this link. First unzip the file. In the resulting Windows subdirectory, a DH53F125.EXE needs to be further extracted to yield a bunch of files. The 2 flash files of interest are named DH53F_1A.fd & DH53F_10.fd.

1. Rename the first 1A file to DH53FX64.fd.
2. Then copy that file to the root directory of a FAT32 formatted USB stick preferrably with an activity LED. It must be the only file in the root directory.
3. Insert the USB stick.
4. Make sure the battery is fully charged and plugged in.
5. Then press and hold the FN+ESC key.
6. While still holding the keys, short press power button to turn the machine on.
7. Don't let go of the keys until LED activityis obvious.
8. If successful, should take about 5 minutes and machine should automatically shut down.
9. If unsuccessful, then try the same procedure with the second 10 file starting with step #1 again.
