We would suggest that you:
- Reset your network settings: Settings > System > Advanced > Reset options > Reset Wi-Fi, mobile & Bluetooth
- Please tell me your mobile network provider
- Please show me a screenshot of the signal strength when the problem appears.
(Settings > System > About phone > SIM status)
- Please change to another SIM card by another network provider, and check if the problem still appears.
- Please also put your SIM card into other phones and check if the problem appears.
Thank you
Hi Jaypatelbond,
Could you tell me your mobile network provider?
Was VoLTE supported on the previous firmware version? Which one was it?
Thank you
I saw that you had commented my post and I decided to help you. OBS: I am from Brazil and sorry if my english turn into a trash kkkk (you all have a brain and are capable of understand my words kkkk).
First - Be sure that you have the ADB and Asus drivers installed. Download the "stock rom of ZD553KL"
ADB Drivers: http://www.mediafire.com/file/cc ... fastboot_v1.4.3.zip
ZD553KL room: https://drive.google.com/open?id ... DXbL_sHr7FK22XsGfW8
Second: Extract the room file to a simple past name and directory like : C:\Zenfone. Avoid put into something complex like the original folder name C:\[up_vnROM.net]_WW_ZD553KL(ZB553KL)......
Okay... lets do it finally
Put your ZD553KL into fastboot mode (press volume - and power button at same time and after appears the message "fastboot mode!!!" you can connect your usb phone on (in?) your computer.
Go inside the room folder and find the .cmd file "flashall_AFT.cmd" and run or open it and wait until it finish. OBS: if the cmd file stop just press some key in your keybord that it will keep going.
OBS2: If the .cmd file does not open, you had to extract again the file and verify if you phone and adb drivers are okay and if the files are in a simple directoy as I said.
Hope have help you.
So what now we have to revert to Oreo?
