As I said in another thread, I'm working on deciphering ancient Jiroft inscriptions of Kerman, Oldest Evidence of Written Language.
Just about those two short texts in linear Elamite script:
I see the words of Kerman and Gedrosia (name of Jiroft on the early the Arab-Sasanian coins was Gedroft), it seems very possible that both names have Indo-European origin, so the original inscription could be also in an Indo-European language.
Map of Gedrosian admixture:
These are only from 1000 BCE though. It's likely that Indo-Euro Iranians were already there by then. In other words, those names could be Persian or some related Iranian language.
