Hi I was asked by Ting support to throw my question out to the ting army for help. Some background on my phone, it's a Sprint galaxy 3 that I picked up on ebay and did a factory reset and activated to ting with no issues. Then a few days after it tried to do a system update and it started to fail after it initiated. I included some screen shots.....it's mentioning 'signature verification file failed. The ting support is mentioned 'rooting' (which to be honest I don't know anything about the process). Ting is telling me I should try to get information on how to where to get the stock ROM to fix my phone. Has anyone run into this issue? and if so, any help would be appreciated.
