Hello everyone! I'm new here, so I apologise if I'm a bit of a n00b. I bought a Samsung Galaxy 551 running GT-I5510T in Australia from Telstra about a year ago, where they told me it was running FroYo and I could easily upgrade. I want to upgrade to Ice Cream Sandwich or Jelly Bean (preferred) but I've heard it's not possible with this phone. I tried installing Kies 2 on my Mac (which runs Lion) and it said that my phone wasn't supported. Should I root the phone? (If so, how would I do this and how can I upgrade?) Or is there somewhere I can download & install firmware from? I've found this: SamMobile Firmware Page (I hope the link works) but it's for Brazil - would it work? If needed, I can get access a Windows 7 computer but would rather do it from my computer. Please provide instructions/a link to some, as I'm not great at this sort of thing. I also found this: http://www.tsar3000.com/Joomla/index.php?option=com_content&view=article&id=334:how-to-update-firmware-of-samsung-galaxy551-i5510&catid=57:how-to&Itemid=104 but it looks rather dodgy. Thankyou in advance! I'd really appreciate your help, as it's been a complete pain in the ass.
