I received a used handset from ebay (for a fantastic price!) and it has an outdated version of Galaxo ROM on it. I want to return to the latest official Samsung ROM (whichever that is), so that i can then do some comparison benchmarks before moving to the latest GAOSP. Can anyone help me with a couple of questions? 1) How to return to a stock ROM from Galaxo ROM? 2) Where can I obtain the latest ROM and which is it? Intended use is in UK. 3) Does anyone have any idea about when the next GAOSP (full) Beta will be? PS: I have never done this process, so please humour me and give me detailed instructions Thanks a lot in advance!
