Phone stucks on boot loading.
wipe data/factory reset gives E:failed to mount/ cache error
wipe cache partition also fails.

Many same post suggest TWRP but i don't have it. Did not understand how to install it on a phone can't open.
Many more says EMMC chip is dead. I hope it is not. I know it is very likely but i want to try other options first if i can.
