Dr HD F15 Frozen (Reflash/Boot from Serial or USB Ports ?)

[moonbase]

Hi,

Does anyone know if it is possible to rescue a Dr HD F15 receiver that is frozen when turning on from a normal bootup?

For example, is there a loader app that can be used to connect to the receiver from a PC via the serial port to reflash the firmware?
Or, is there a procedure to boot it from a USB and rewrite the firmware from a USB stick?

The F15 was an earlier model to the Dr HD D15 so any rescue procedure that works for a D15 might also work for an F15?

Should be able to do same as the TM 5402 recovery hopefully
Turn the TM 5402 'Off' using the power switch on the rear of the receiver... then press and hold down the 'Menu' button on the front of the receiver as you switch the TM 5402 back 'On' using the power switch on the rear of the receiver... you will then see the 'Loader Menu' on screen... try the 'Factory Reset' option on the list and see what happens...
Also try the 'USB Download' option...

Switch the TM 5402 HD OFF using the power switch on the rear of the receiver... insert the USB Flash Drive into the receiver as normal... then press and hold down the POWER BUTTON on the front of the receiver as you switch the TM 5402 HD back ON using the power switch on the rear of the receiver... continue to press and hold down the POWER BUTTON until you see the BOOT LOADER MENU on the TV screen... then release the POWER BUTTON... you will see two options for loading firmware/files... however the BOOT LOADER program usually scans the USB Flash Drive and downloads the latest/most recent firmware automatically...

Make sure you have only tm fw on usb.

Maybe try original TM fw

Many thanks, it worked.

The menu button and power button option brought up the loader menu from which I selected factory reset.
Once that had completed I rebooted the box and loaded a channel list backup from USB.
