flashing twrp on lg g4 no error, but no twrp I'm trying to flash twrp to my lg g4. I've reached the part where I run 

fastboot flash recovery twrp.img


And everything seems to work fine, but when I try to enter recovery mode, I get the default lg recovery (restore factory mode options) and not twrp.
Here's what it prints out when I run the flash command:

target reported max download size of 536870912 bytes
sending 'recovery' (32060 KB)...  
OKAY [  0.827s]  
writing 'recovery'...  
OKAY [  0.341s]  
finished. total time: 1.168s  


What am I doing wrong?
I tried doing it from a different computer and tried flashing older version of twrp.
I solved the issue..
Apparently, when you enter recovery mode, the phone asks you whether you'd like to do a factory reset, and you choose yes it boots into TWRP :)
Hope it helps someone.
