i'm thinking he/she typed too quickly
llop
instead of
loop (given it's about removing the PG05IMG file which would send your phone into a bootloop if you hadn't removed it--i think this is the most plausible case)
i don't recall ever seeing "llop" as a shortened form of any commonly accepted phrase while rooting like "bsod" for blue screen of death" for a computer
you were probably kidding with the question--
but in case anyone else was wondering & wasn't familiar with terminology used in the forums, there ya go.
