hello all, I currently have 2 friends who both have Lg optimus S on sprint. Both of them did accidentally update with the OTA and now do not have a rooted version of android. I was able to manually downgrade them back to V9 but I am unable to get data working. I am also unable to upgrade the PRL and the data profile. So how do I go back to a stock rom or can I just put a rooted stock rom that will allow me to periodically upgrade the PRL and data profile?? Thanks again in advance.
