Hi, my phone is giving me grief as described in title. Have followed various links to try and help prob. So am about to try rooting and flashing. First purchased Rom Manager as not very tech and happy to hear of app that would do job for me of flashing rom. Well first eye opener. Rom Manager does not recognize GT-I1900T. Unsure whether to refund it or not because: Have read of apk Z4root v.1.3.0 that seems to be of use for those of little tech like myself. Am planning on using it for root. Then will flash parandroid jellybean 4.2.2 and download google app pack. Hoping this will help stop continuous freezing. Would Rom Manager be of any use after phone is rooted? And parandroid flashed? Thanks for help. Not sure if I am in right forum thought T-Mobile related to type of phone GT-I1900T but after looking around starting tobthink T-Mobile could be a phone company.
