I'm following this guide to root my HTC Desire 510.
I reach the step Step 4 – Root the HTC Desire 510.
I perform the command
fastboot flash recovery recovery.img in a cmd prompt, and I receive the message:
sending 'recovery' (10594 KB)... OKAY [1.352s] writing 'recovery'.... OKAY [0.731s] finished. total time 2.085s
I rebooted my phone, then powered off the phone.
At Step 5 – Install SuperSU, I don't see the option ‘Install zip from SD card’. I don't see Install Zip either.
This is what I see:
FASTBOOT RECOVERY FACTORY RESET SIMLOCK CHECK SMARTSD IMAGE CRC SHOW BARCODE
What do I need to do to Install SuperSU?
