Hi,

More often we get OS Update OS Update has failed to install on our TCxx and MC93 devices.

I use file sync but to avoid corruption i sent the files in the upload from the device directly, i tried the incrementals and the full updates. 

I looked to many documents on the web. I use install_system_update /sdcard/Download/updates/tc57-firmware.zip. Adb is not an option because device is elswhere.
