Manual install instructions did not work (rw error) - LineageOS 20

OS    : LineageOS

I couldn't sideload the zip (the error wasn't descriptive sorry) so I tried to manually install it following the instructions in the readme.

When trying to push the apk it would error as it couldn't write the file. Here's the commands I used.

> adb root
> adb shell mount -o rw,remount /vendor
> adb push treble-overlay-bromite-webview.apk /vendor/overlay/
treble-overlay-bromite-webview.ap...18.3 MB/s (16815 bytes in 0.000s)
adb: error: failed to copy 'treble-overlay-bromite-webview.apk' to '/vendor/overlay/treble-overlay-bromite-webview.apk': remote couldn't create file: Read-only file system

I came across this as a possible solution using adb disable-verity and it worked:

> adb disable-verity
> adb reboot
> adb root
> adb remount
> adb push treble-overlay-bromite-webview.apk /vendor/overlay/
treble-overlay-bromite-webview.ap...74.7 MB/s (16815 bytes in 0.000s)

# and the rest of the tutorial...

and I managed to follow the rest of the install instructions with no problem. I now have Mulch System WebView working.

I don't know if the tutorial itself is broken, I could have just done something wrong or my phone just didn't want to cooperate. But figured I'd write an issue as the install-guide didn't work for me.

Thanks for the project btw :)
