well i came into having my old eris back which had since been rooted and i went thru these directions on here
How To Downgrade your Rooted HTC Eris back to 1.5 - HTC Eris Root How To's - TheFuzz4.net
to go back to 1.5 and i assume un root? being this was the site it was rooted from.
now is eris on 2.1 or still 1.5
do i need to have it connected to a service plan to update if thats the case. i want to give it to my gf close to stock as possible since her ally is crap
