How about: wipe data/factory reset? That might bring you back to the state it was in when you bought it.

I tried to root my samsung galaxy s5 model: SM-G900V with the directions on this page
http://androidbiits.com/root-verizon-samsung-galaxy-s5-sm-g900v-android-4-4-4-kitkat/
I got to step 6 and now my phone says Android system recovery <3e>
These are the options it gives me
reboot system now ---- i have tried this one
apply update from ADB
apply update from external storage
apply update from cache
wipe data/factory reset
wipe cache partition
reboot to bootloader---- i have tried this one
power down ---- i have tried this one
view recovery logs
The options I have tried just turn my phone off and back on and bring me back to the same screen with the same options. I have no clue what to do and I'm freaking out. I'm a dumby when it comes to this stuff, so anyone who could give me step by step instructions would be a life saver.
