Hi,
I have the same androidtv stick as yours (from the dx site) and I needed help getting the second part of stane's rom installed.
I tried stane's original firmware and installed it twice as per stane's advice to get both the core and the apps installed but the apps do not get installed for some reason.
Next, I tried your 2 part flash, the first part flashes fine, the second part states it is missing required files to update. I looked into the factory_update_param file and found these lines:
--update_package=/sdcard/update.zip
--update_patch=/sdcard/new_patch.zip
So it's looking for the original update.zip, so I just copied new_patch.zip and renamed it update.zip. Unfortunately that doesn't work because I get a null error since it boots into recovery.
Do you have any suggestions?
