Recover Dead ***box/Openbox Flash Using Serial RS232 Null modem Cable

A how to guide on how to fix a corrupt firmware image in the OpenBox S9/S10 and ***box S)/S10 Even if it seems bricked.

This guide is taken from another forum so big thanks to auther.

Box does not respond or displays On?
If your box does not respond, or no displays light there is a good chance the current firmware on the box is somehow corrupt.

You will need to use this tool, connect a Serial RS232 Null Modem Cable to the box and follow the instructions.
Hopefully it will bring your box back to life.

1. Connect up your PC to the ***box/Openbox
using a null modem serial cable.
2. Switch the box OFF
3. Run EromUpgrade.exe then check the
com port setting is correct
4. Select the latest firmware .abs file. (Download her if you don't have any)

Important: Go into device manager (goto start-->run-->type "devmgmt.msc" )
or right click My Computer--->manage--->on the left side u find device manager

and check that you are choosing the right com port. If possible use computer with serial R232 com port built on mainboard.

Only thing I would like to add to the above post is to tick the include boot loader option.

Good luck.
