Chinese new year has already ended. You took a lot of holiday and enjoyed it. When will we get a answer ? Or due to Corona virus, you can't contact China division(factory). You knew that all serial no are same.C4ATAS000000 adding Google play protect indicated "not certified" is occurred.

I have received a mail from Selena-Asus. I didn't know till yesterday. It follows: Hi svraffter There are ZenFone Max Plus (M1)(ZB570TL) which are illegal sold by our vender. Therefore, if customer encountered unable to update FOTA issue with WW_14.02.1809.70_20190708 version for ZenFone Max Plus (M1)(ZB570TL), please follow below steps to guide the customer to verify: 1. Please ask customer to provide the serial number to verify product condition. 2. If customer’s serial number is less than 15 digits and the 3rd and 4th digit is not ”AX”. The device is considered as Non-ASUS genuine goods. 3. Please ask customer to seek for service from original disti/ dealer or original purchase channel. 4. Customers can also follow the steps to verify product condition by themselves: Please go to ASUS Official Support Site and enter serial number on warranty status search page. The way to get serial number is: (1) Find the serial number in “Settings” -> "System" -> ”About phone” -> ”Status”-> ” Serial number” (2) Serial number is showed on the sticker label of the device or the package box.(The serial number is listed after the word “Serial Number,” “SSN,” “S/N,” or “SN.”) If the system shows” The serial number you entered is not valid” ,the device is considered as Non-ASUS genuine goods. Thanks and have a nice day. 2020/2/5 09:01

After that I have sent some quetions to Selena Asus, but no answer. And I contacted Aliexpress(seller) and explained all this problem(It can't update Android 8, serila no. are all same no. , Google play protect certification inidacted device is not certified. )Showed letter from Selena Asus . Today I got a judgement and I will get a refundt without returning. I think aliexpress is very kind ,excellent and wonderful. :lol:lol Next I will buy this site. If someone have same problem, try to do it. You may get a refund.
