It seems the broken touch problem above happened due to flashing the files in the 1st post files which were from older firmware onto a device running newer firmware. Can I use the firmware extractor here to download the latest firmware and root it with magisk?

Alternatively, wouldn't using EDL mode to extract the latest firmware then running magisk work? That would seem to avoid the touch screen loss issue since firmware versions wouldn't be mixed.
