I reset mine the other day with a brand new TTL cable. Relatively simple operation. Great instructions in the GEOSATpro microHD TTL udf Update.pdf within the Satellite AV link above.
Your cable isn't connecting to the MicroHD. Are you choosing the correct COM port on your pc? That's the most likely problem. You might consider using an older one running Windows XP if not already, but go into Device Manager and confirm your com port. Or try 1 through 5 and see which one works.
The LED will light up as the cable supplies the 5v to power the chipset. This does not indicate that the correct USB port is assigned in the ALI Editor.
If the driver installed correctly, the PC device manager will show the com port assigned to the USB/TTL convertor device. Select this port in the ALI editor.
My guess Kraven is you don't have the com port on the right number, as stated above. I know you are running XP as stated before so if you don't see your serial port com number assignment in Device Manager; keep trying different ones starting at 1 until you hit it.
Lets sum up. Each port I tried popped up "port error" (or something to that effect) except for COM3. When I tried to load the latest firmware:
TEST SERIAL PORT STATUS: FINISHED
COLLECT STB Information: Failed to get Version
OS is XP on rarely used laptop (except for Satguys radio streaming).
Is it normal that while connected to USB, the receiver still flashes green/red? I hope its not a total loss since Ive literally used it for less than 2 hrs.
1. Did the driver for the serial USB/TTL adapter install properly?
2. Does the PC's device manager detect the adapter and if so what port?
If the device manager does not show the device, it is not recognized and the driver may not have installed. The cycling red/green LEDs will occur if power is applied by either USB or radial power connection, but the serial communication is not made to handshake the STB and the PC.
Changed laptops (w7) and the driver installed properly. After that she was smooth sailing on "unlooping" the receiver.
Gotta give credit where its due: A popular saying amongst cusumers is "you get what you pay for". SatelliteAV and company (Brian, Ke4est etc) definetly prove the opposite.
The after sale support for the MicroHD far surpases its price tag.
Mine is now doing the loopy thing, just went to update the receiver via the TP on 97W, loaded the update, and yes to re-boot and it won't stop rebooting.
Noting the TTL pins on the circuit board, what is the pinout for these to a DB9 serial? Will try loading the software using this method. What baud rate?
