There is another Chinese universal firmware based on 1.4.4S posted recently on hdpfans available at:
It is originally posted by akira on hdpfans forum. According to the instruction, if you extract the file and put image.img and tag_install on the root of your thumb drive, it will automatically start the flashing in 33 seconds upon start up. Alternatively, you may just use the image.img file after clearing the firmware using the traditional way.
I have not tested this version yet but the previous 1.4.4S. It works really well and I have not experience firmware corruption since I flashed to it last month. It is rich in Asian IMS content but you will need to understand chinese to find the way. The new version has improved remote control responsiveness, customerisable IMS channel buttons, and using internal or USB drive as cache for streaming.
By the way, Youtube is working in this firmware and Transmission should be included too.
