Can I recover bricked device from Mask ROM mode?

A note of warning, btw : after flashing my eMMC to put manjaro/phosh on it, I booted with an other OS on the SD card and realized that while the root partition I was using was indeed the one from the eMMC, the boot partition was the one from the SD card (basically, the phone booted on the SD card but mounted the eMMC's OS). While it does not cause any immediate issues, that would have ended poorly in case of updates, with the eMMC OS updating the SD card boot partition. I don't know if uboot put anything in root partition, like in /usr, but that would mean having half a version on the root partition and half an other version on the boot partition. Anyway, that can't be good 
Removing the SD card booted properly (and fully) on the eMMC, and then I reformatted the SD card to make it be a data partition.
Also worth noting that after flashing the eMMC, the trick "short press power to boot SD card, long press to boot eMMC" mentioned on the wiki does not work anymore for me (it may just a matter of uboot configuration). But this is no issue, as I can just use the RE bypass if I want to boot a SD card to try something.
