Alright, so I have a few ideas.
1. Try flashing a new rom via fastboot. (the following is based on the assumption that you have adb and fastboot in your path)
Flashing a ROM through Fastboot
So Why Do I Need To Do This?
You don't, normally you would flash a ROM through recovery, but why not have another way? Maybe your recovery partition on your phone is corrupt?
Maybe you just want to say "I learned something new!" whatever your reason here are the simple steps:
We need to download the ROM of choice to your computer. Once complete find the folder that rom is in and open terminal/cmd to that directory
(quickest way for windows; just hold shift and right click within that folder > open command window here) of course make sure your phone is plugged into computer and in fastboot mode.
Lets see how quick and easy this really is...
In the command line type:
Seeing your serial number means we know all is good
Now lets type these commands:
fastboot erase system -w
fastboot erase boot
fastboot update superawesomerom.zip
Of course replace <superawesomerom.zip> with the correct file name
and last but not least:
2. Boot into Recovery via fastboot.
Plug phone into PC, connect with USB cable and have phone in fastboot mode, now open CMD/Terminal in the same directory as your recovery image
fastboot boot recovery.img
Of course name image correctly to fit command or vise versa
Now you are in recovery of choice within your device without it being flashed to your recovery partition. There is a time and a place for everything, can you think of ways this may help you? Sure you can!
This doesn't actually flash the recovery.img... it will just allow you to boot into it. Make sure that you have a good TWRP version.
