The latest FOTA Version 2007.27 is not getting downloaded. System update is indeed detecting the .27 Firmware FOTA but after hitting the "Update" button, its showing "System update failed" popup with a message showing "Your system is reverted to its original configuration".
Screenshot is attached :
P.S. : After facing the problem, I cleared the cache and the data of the "FOTAService" system app and restarted the device. But after restarting, the issue is still happening.
