Hello,

once i flashed on the recovery modus from 2.5.xxx to 3.1.xxx and last to 3.5.259 ST. Now i can not importing future OTA Upgrades without FULL OTA on the recovery modus. It was fine to go to the latest Version 4.0.xxx. Was this special Updates? I have any update.zip Files tried. She ending with an Error.
