Transfer avatar award or trigger achievement on different account to facilitate that

Wife and I shared a 360 and I had beaten arkham origins on her account not knowing about the awesome deathstroke avatar costume that unlocks when you do. I was hoping due to not having access to a 360 any longer if I could transfer the award from her account
or trigger the achievement on mine as a means to the same ends. We've got a little one at home now and pretty crummy work schedules, even with access to a 360 going back and beating origins again is just time we don't have. Please help! T.T

cant recover my account.

Are you saying every Avatar award you unlock isn't showing up in the Avatar Editor, or just certain ones? Which ones? Are other accounts able to recover to your console? Can you recover your account to a different console? If so, transfer it to a USB device
and physically bring it to your console.

 

I removed my avatar award from HDD

I accidentally removed my avatar award from HDD.

Removing saves and playing horde again didn't help me Achievement unlocked already.

Can I recovery my awards on current profile? On avatar settings by xbox.com this award haven't too.

P.S. One moment! I found something strange. I have two profiles (they saved in different devices). I wrote about my profile here. But today I try to remove avatar award from friend's profile from HDD. Then I go to avatar editor (with friend's profile) and
found that I can download deleted award. But on my profile it is haven't. There's shows that I must to unlock "Horde beginner" achievement to get award and actually achievement unlocked already. And in the game's statistics displays that I unlock this achievement
and this award. And there was file's on HDD for this award which I deleted later. And I remember how Xbox notify me about unlocked award! But in avatar editor displays that award locked. So strange! There is obtained that removing files from HDD doesn't have
a relationship to this issue. I think when I unlock this achievement files wrote on HDD, but Xbox OS didn't add records in avatar about this award. Therefore I can't see my earned in actually award. It's bug?

P.S. Sorry for my English - I am from Russia

 

Hey,

Unfortunately, the option to transfer content such as Avatar items and Achievements in which the avatar item was unlocked with cant be transferred to other accounts.

However, congratulations on completing the game though Happy Gaming!
