Suggestions for Manual update
1. Model name : Asus_X00TD
2. Firmware version : OPM1.WW_Phone-15.2016.1902.340-20190216
3. Rooted or not : No
4. Frequency of occurrence : permanent
5. App name : FOTA service
The problem persists from buying of the phone. I can't update via the system update option in my phone. It doesn't shows any update available for my phone.
I want to know that is it safe to update my phone via Manual update directly to latest firmware version WW-16.2017.2005.082 (1.53 GB) available at your website or should I update it stepwise (i.e from Android 8 to 9 & then 10)
