I haven't rooted my phone. i unlocked its bootloader. But before i've unlocked it still giving me the"error footer is wrong" or somethin . Im trying to update android 10 manually using recovery.

I've downloaded the WW_17.2018.2004.424-user
Pasting the file on root directory means i should root my device?
I hope you would help me thank you maam

Hi Mercc
Thank you for your reply. Because you already flashed custom ROM, there may have some unexpected side effects. Please try hardware reset and upgrade to Android 10. If the issue persists, kindly check some power user website for further checking.

# Hardware Reset Guide/Access recovery mode for the Factory Reset:
0. Try to back up your data with USB cable. If you can not access the phone, please check if your google account or microSD card have auto backup your data. 
1. Power off the phone, then keep pressing "volume down key"
2. Press "power key" and stop press " power key" once you feel the vibration. Still keep pressing "volume down key"
3. Stop press "volume down key" once you enter [Android Recovery] Screen
4. Choose "Wipe data/factory reset">"Factory data reset"
5. "Reboot system now"
Please note that once the steps are completed, all data, apps, settings and personal information will be deleted.
