I asked Harrysmith for additional instrutions and this is what he replied:
lok in you tube "how to ubrick apad" and in the part 5 video is the way to do it. I needed to unsolder the battery as thios device has no real power buttom.
Once you do it your device will be detected as VID_2207 & PID_273A. If the driver is not detected use a generic rk281x of other manufacturer but changing in the .inf file the vid and pid for the ones I mentioned above.
There are two sections in the driver information, change only the one in the MSC section. After doing that the device will be in rock usb mode or MSC mode and it will be possible to install the firmware. My problem now is that I have no correct firmware. I have a backup of the two partitions that appear when you use the htc0001.tag file. Nevertheless, I have no correct bootloader I suppose. I have tried several 2729 but without success.
I hove soon somebody with this device can make a backup copy of the full firmware image.
I hope this information will help. I know that lots of people is having this problem."
I'll be following this steps on the coming weekend, but there is still the problem he told about the bootloader. Still with this, we can get a little bit forward to solving this issue.
P.S. Harrysmith tryed to register himself in this forum, but he never received the confirmation mail. So, if any admin see this, it would be nice to check this out.
