Thanks, but the only .257 firmware that works rooted is a custom rom from here installed via dual recovery cwm, a flasheable zip, and not have the apk.
and flashing the ftf excluding system give various apps ( bloatware ) back, but not the update centre.
i have and original APK and the odex file, copied to system apps, set permisons and nothing.
