My G1 Note recently won't turn on and it loads up to the Samsung splash logo then just stays on it. It isn't frozen, as a blue 'cloud' is moving behind the logo. I understand some say to reinstall OS, but I want to know if this will wipe everything on the phone. I do have most of it backed up, but I have about 100+ photos and some videos I took recently on a holiday that I haven't been able to put on a computer yet so it would be a let down if I can't get them back. Would maybe finding an update on Odin work? Or is a factory reset the only real option? Thanks!
