[SOLVED] Seriously confused K800i Upgrade

*edit* Sorry, I think this went into the wrong section

I really don't understand all of this. My K800 had apperently very old firmware. SEUS and the on-phone update service has never updated so I went about flashing the phone with Phone-XS. Using more luck than skill, I successfully upgraded from R1ED001 to R1GB001, both on Red49. I lost all my settings, phonebook etc, but hey, VERY new to this. The new update has also not included the Update Service on the phone - it's just not there!!
So have I got the latest firmware now? There are a huge number of files available apparently for the K800i but many don't even start with R1.....
Any help - in really plain simple terms - will be greatly appreciated.

Hi. Dont update it with SEUS because it will upgrade your phone to CID53 and you dont want that. They have messed up a few k800.
