eMMC probably became write-protected. Only way to fix that is by JTAG. Problem is, if you don't have a full backup of the phone (which you most probably don't have), then after JTAG there is a high chanche that the phone will be stuck in airplane mode with none of the wireless communication features working.
So if you get somebody to repair it for you, make sure they backup the chip before fixing it, so you can later fix wireless functionality

With the Samsung eMMC Write protection being turned on, none of these tools can do anything, and NO, even Android cannot be installed to the phone without first repairing it.

One thing.
My friend ended up with the same issue as this.
Question - how do you differentiate emmc write protection and emmc death in these cases?

Because apparently where he went to fix it, they wanted to charge quite a bit because they had to replace stuff.
