Hi everyone,
got a brand new ZS570KL with TIM SKU. Android version onboard is Marshmallow (TIM_4.11.40.1217_20161014). I dowloaded from ASUS website latest available FW for the TIM SKU based on Oreo (UL-Z016-TIM-15.0210.1807.67-user). Followed instructions for manual update but after some minutes I got a FW update error with dead Android picture and red triangle on it. There are no log lines that explain the cause of the error, just the picture is shown.
After rebooting I get an error poput saying:
System update failed. (3) Unknown error. System restored to previous configuration.

I then did another attempt performing manual update by placing the same update file on SDCard and using the Recovery mode. The error message I got was: The version is unmatched. Error in /sideload/ (Status 7).
I got the same error trying with a different update file (see attached screenshot).

I assume the cause is that the starting version for the update is too old, i.e. it is not allowed to update directly from Marshmallow to Oreo.
My questions are:
- how can I know which is the minimum FW version I need to have installed beforer updating to a certain target version? The release notes contain no such information
- which update steps should I perform for updating to Oreo from Marshmallow? Only available TIM SKUs from ASUS website are:
UL-Z016-TIM- (Nougat)
UL-Z016-TIM-15.0210.1805.54-user (Oreo)
UL-Z016-TIM-15.0210.1807.67-user (Oreo latest)

Thanks for the help

Hi Selena,
got your advice, PROBLEM SOLVED, below a recap of the solution:

- Factory version on phone: TIM_4.11.40.1217_20161014 (Marshmallow)
- No OTA update notification
- Downloaded UL-Z016-TIM- (Nougat) from ASUS website and installed manually from recovery mode
- Phone successfully updated to TIM- (Nougat)
- Immediately got a notification for OTA update available
- Accepted OTA update
- Phone successfully updated to TIM-15.0210.1807.67 (latest Oreo available)
- Phone works perfectly, no battery drain, no autofocus issues whatsoever

This is a great news for all Zenfone 3 Deluxe users in Italy where the device is sold by TIM carrier as an exclusive. Many people complained they were stuck to Marshmallow, this is the way to solve!

Thanks a lot!
