System update failed (Your system is reverted to its original configuration)
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.

Kindly look into the matter dear ROG team.

If you are unable to update to WW-17.0240.2007.27 using FOTAService, please download the manual update file from our support site and install the new firmware that way.

If you are unable to update your phone using the UL file as well, please send me a PM with your device SN and the two IMEI numbers. (Settings -> System -> About phone -> Status)
