Once recovered, it did not update with the information from the offline version i had been using whilst i had no internet.
However i can still continue from the save, so the information can't have disappeared, just the achievements have not updated. each save is also saved with a console code to prevent people from just copying each others saves/achievements and cheating games...
I had the same problem with my gamertag a few weeks back and have not found an answer either.
When i came home i was still using my gamertag offline.You don't have to recover at all anymore and the achievements stay.You just have to copy the profile from the HDD to the card.Then i bought Burnout paradise and proceeded to play it and gain achievements.Recently my Internet connection has been fixed, so i went on my 360 and recovered my gamertag back from my friends 360.Hey, i'd be grateful if anyone had an answer for the problem below.OK, so i didn't have an Internet connection for a while, and was using my gamertag offline.HD(just recovered what you originally recovered at your friends because your whole experience at friends was offline... the only way around this is to completely copy/clone one HD to another with the transfer cable which also wipes the one being copied clean... the only way around this is to completely copy/clone one HD to another with the transfer cable which also wipes the one being copied clean... The save is tied to a gamertag, not a console code.so none of it was sent to the LIVE servers so when you recover... you can save data on the memory card and then transfer it onto the HD... you can save data on the memory card and then transfer it onto the HD... If the GT is avaiable either through an HDD, memory card or GT recovery, the save works as normal.My point is not that they have been lost as such, just that why, when using the same profile, did my achievements disappear, just because i went from offline to online. when you are offline the only place that knows you have the achievements is the HD of the console you are using... What i still fail to understand is why back on my 360, with my LIVE account recovered, my HD does not update it with the new information.I thought it updated your online profile when ever you signed in. the only way to update the achievements is to reload your profile there... and until you connect to the LIVE through the internet... I can continue the saved game on the LIVE account (which i originally saved offline) but alas no achievement update.
