E:format_volume: make_extf4fs failed on /dev/block/mmcblk0p27
I think it would be great to first check and to be shure if it's eMMC problem or not.
How to check this (one of example):
Try to install some other Recovery.
If you pass without errors turn off phone and pull out battery for few minutes. (if you get errors in installation, try few times, or try with different recovery, but just be shure that you not installing the same you allready have)
Put battery back on and turn on phone in recovery. Check is it really there and installed.
If you succesfuly installed diffrent recovery your emmc is working and you can fix it.
If you don't get errors, install it, and after restart you see that you have your old recovery, it's probably problem with your emmc. We can try more things to be shure.
