58w ago - Below is a video tutorial from GameBlamer on YouTube demonstrating how to dump PS Vita games via the recently released PS3 CFW 4.21.
It has not been confirmed yet and I am not the uploader, I just found it randomly so consider it a proof-of-concept if it ends up working or an 'entertainment purposes only' video if not.
The video is partly in English and part in German, and although it can be followed if anyone wishes to translate the German parts to English or make a new video let us know and we will update this article with it... those interested can check it out below!
Finally, from wololo (via wololo.net/2012/10/25/backing-up-vita-games-using-the-new-4-21-cfw-by-rogero/) on the above video to quote:
Backing up Vita games using the new 4.21 CFW by Rogero
Have you ever worried about Sony's financial situation, and what would happen to your hard earned Cash if they were to close? I certainly have.
For a long while now Sony have not been in the best financial state and could possibly face bankruptcy in the future. If this were to happen, then their servers would go down, meaning that there would be no more PSN/SEN, subsequently all of your purchased media would just vanish into thin air.
However, this is no longer an issue! (At least for those who own a Playstation 3). With the release of the LV0 keys, and CFW on 4.21, if you were lucky and updating didn't brick your console, then this is for you. For those of you who do not have 4.21 at present, fear not! There are apparently multiple people working on getting CFW on 4.25 and even 4.30 (and considering they have the LV0 keys, that probably won't take too long).
Be advised however. I have not tested this since I am still on 3.55, but the person who posted this is rather reliable from my own personal experience.
If any of you are able to test this then please let us know! If not, sit tight - it won't be long!
Please be advised that this video is mostly in German, but it's easy enough to follow.

i had the same problem with Multimanager on 4.21 cfw, i downloaded new version on pc and the installed over usb and now works fine! i was lucky and update to 4.21 without brick, just wait couple days and then try again, something new will come!
I updated to Rogero 4.21, I had Rebug 3.55.2, when i tried to open multiman, the screen just turned black and the console got stuck, so I restarted it and did it again and I got the same result.
so I decided to go back to 3.55 to be able to enter multiman and get the latest update, so I used the 3.55 to 4.21 PUP and I was able to return to 3.55 and then I tried to update to Rogero 3.55 v.7 like it was written in the instructions and I got an error and could not update.
so I tried to do it with Rebug, kmeaw, OFW 3.55, and Rogero 4.21 again and none works all get the same error, I tried through XMB and System Recovery. So now I cannot update to anything, but multiman and my 3.55 games do work, but I want to update to 4.21, what sould I do? please help me!
I havent tested a spoofer and reactpsn on 4.21 Yet , but im 99% sure we are offline for now
Want my opinion , Format your drive back to original , Run QA Toggle and condor updater , Install 3.55 ofw , Then update to Rogero 4.21 , (BUT! MOST IMPORTANTLY!) , Run MD5 Checksum on all the pups you use before you update , To make sure the files are the correct size , I did and i had no problems
