As per the instruction in magisk, I patched the stock boot.img again this time with "Preserved vbmeta in boot image" then flashed "same issue". Next was checking the 3 options then flashed again but message still appearing during power cycle. I also read that fastboot in our device is factory disabled and inaccessible so doing that fastboot command is not the right method for our device.

ohh sht dude i think this is the reason why you have the broken dm-verity message in the screen its because you disable it while patching the boot image which is wrong to be honest( it depends though) try patching your boot image again but this time dont check anything just leave it be ok and tell us if the message is gone

why do you want to delete the bootloader partition? it will remove the bootloader unlocked state and it will corrupted the phone

actually the first time I root this device, I used the boot.img provided by @Zezo 089 and I thought it was normal to have that message after all the steps and then that's when I tried patching boot.img on my own but still issue persist though.

Okay update bro, I tried patching the stock boot.img with magisk and all 3 options unchecked and then flash again but it didn't get rid of dm-verity error message bro.

owh, good thing I didn't try this method yet.

here bro its a vbmeta image if you still need it its for oppo a5s only

do you have other method how to access fastboot bro? based on my research, I think fastboot on this device is disabled so I cannot apply the fastboot command, did the "adb reboot fastboot" and combination key already but to no avail.

Bruh
I found it
+ I didn't know it will remove the Bootloader partition, it will remove something has the dm-verity + vbmeta verification + got it from a website

well I was pertaining for this solution bro but forget about this now that this device doesn't really have fastboot enabled.

yes your right it will remove the message because you will remove or relocked the bootloader also doing that will corrupt the phone making it unable to boot because of an authorized boot image, bro @Zezo 089 not all in the website are true we need to research more before doing it we might screw up if we dont

Actually bro, like I said before, I used your boot.img you provided here when I'm still on the process of rooting my phone, I didn't patch magisk since you provided the img already but after all the process, I got the "dt-verity error" and I thought it was a normal thing when rooted already.

he patched boot.img file ( to save your time instead of getting the original file from the frimware (rom) and patch it , i thought that providing a patched boot.img by magisk app may help !) : here

Well, if this doesn't limit the functionality of the phone then I could leave it be , right?
