Rooting and true radio s-off is amazing and will help with other problem, just not a fried emmc, not even JTAG can fix this
Soldering a new chip is tricky if you haven't done real fine soldering before, so be careful doing it yourself
Depends how and where you bought the chip, many vision specific ones come preloaded with firmware/software
If it doesn't you will need JTAG equipment to flash it
Hope all goes well for you!

Hello.

I would not do the soldering myself. I was talking about some friend who has the tools.
Anyway, the JTAG thing is a no-no for me then. Too much complications.
I was assuming that since my fried eMMC did not totally incapped the phone (HBOOT bootable, Fastboot visible, etc.), I should be able to flash any new eMMC, at least with the last method you suggested.
I don't think these thoughts are total nonsense.

No not total nonsense, legit question
All partitions are located in this chip, when it fries or is replaced you are left with a logicboard and no brain to it. The new chip would need the partition table flashed to it if it doesn't come with it. This would be something to ask your supplier as I have seen this chip sold before with partitions flashed to it already so the best answer is maybe

If it comes with FSBL ("file system boot loader"), that's a hint it's partitioned?
