Can I run Android from an SD Card? The eMMC in my phone is dead I have a Mediatek based phone, Alcatel 4030x, and it is slowly dying.

The System partition is now mounted as read-only, then apps start crashing after a minute or two.

I've tried SP Flash tool, restore stock rom, and numerious other methods, but I'm 100% sure the eMMC is the dead so these methods do not work.

Right now I do not have the equipment or skills to replace the eMMC, so I was wondering if I can run Android from the SD-card?

Someone else on this site managed to run Android on his Samsung phone using the SD card, so I tried his method, but it does not seem to work for my phone, here is the method I found:

Use sd card as internal storage and stop writing to internal memory for good

I partitioned the card, edited 'fstab', but the phone does not boot from the SD card, is simply sits there with a grey screen when I turn it on.

Has anyone else managed to do this as right now the phone is about as useful as a chocolate teapot! Thanks
I'm having a kind of related issue with my Moto G5s (xt1794) right now. I hard-bricked it and now it won't boot. There are some guides about flashing a fully functional image onto a sd card. After pressing the power button for 1-2 minutes the phone boots. If I switch it off and remove the sd card it won't boot again, so i guess it is really booting from sd card, not just installing the software into emmc or something (which would be more useful in my case). Anyway I think this could solve your problem.
