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.
me too.. I am not sure about what to do, whether I should go for the manual update or wait for the FOTAService to get fixed for which the system update failure issue is happening. FOTA is of about 158 mb while the manual update file size is 2.29 gb! though data is not an immediate concern for me, but what if in future updates, FOTAService still acts like the same? That would be like we would always go for the manual update only if the issue keeps happening. I think we should wait for the fix this time only. Lets see what Asus does to address the concern as I have shared the log file as well as the screen recording video with the Mod as per his request and he replied that he had forwarded the files to the dev team. Lets just wait for few more days.
I'd just list the steps for manual update here: 1. Download this fota file (158mb) https://fota2.asus.com/delta_package/phone/WW_Phone/formal/17.0240.2004.9-user-WW_Phone-17.0240.2007... 2. Place the downloaded file in internal storage (not in any subfolder) 3. Rename the file to this: UL-ASUS_I001_1-ASUS-17.0240.2007.27-1.1.204-user.zip 4. Reboot your phone the notification for updating will pop up click yes and the process will start As easy as that! If any of you are wondering that fota/manual update has any difference believe me there isn't I've manually updated my Zenfone 5z many times without any issues
