HI all,
My Vita is on 3.10FW. I have setup qmca but when I unplug my vita at the copy content bit and it errors on the screen and I plug it into the PS3 and try to send over Network Media Player it errors at the end with code E-80558325? anyone know how to get around this? I have my vita on plane mode, no network, vita turned off and back on again using qmca but stuck at sending over the player. I'm trying to follow this guide using a PS3 on OFW. I was hoping to use pexpolite lite cause I have not got a idps.bin file being as though I'm on 4.70OFW on PS3:-
1. create a lightweight backup (no games\saves\videos etc.) on your ps3??? Dont Know
2. go to ps store and download any ps vita app (i got Network Media Player, but it should probably work with any other app), then make another backup??? Dont Know, how do you make a back up on a USB stick on your ps3? it will not let you?
3. extract the whole second backup with ps3xportgui???was going to use Pexploit lite for this bit
4. search extracted folder named dev_hdd0 and locate the folder with your downloaded app (mine was in dev_hdd0\vsh\game_pkg\80000001). inside there should be a .pkg file along with three others (d0.pdb, d1.pdb, ICON_FILE). copy this folder somewhere, but recreate the original folder structure (i.e. newfolder\dev_hdd0\vsh\game_pkg\80000001 in my case). extracted backup folders are no longer needed, you can delete them
5. open the folder you just copied, then replace the .pkg file with psmdev.pkg, but keep the original filename (i.e. VTXgiSAPiRkiRGYEShqfBDtjjmwoOKtEbCMHBMBsWRmgmyiPsCNMTzwEpguevtUj.pkg in my case)
6. add the folder from the previous step to your first backup from step 1 (use the 'Add from an existing copy-protected Backup' option in ps3xportgui), then restore this backup on your ps3
7. connect your vita to ps3 by using the QCMA trick, then transfer the app to your vita. it will be listed as the original app you downloaded in step 2 (Network Media Player in my case), but it's actually psmdev assistant.
8. install this update via package installer and you're done
some of these steps are probably unnecessary, but this is exactly how i did it. my vita is on 3.18 btw
Can anyone help me out on this please

I already have the installer package set up just need to somehow get the dev menu on my vita? These instructions are not exactly clear for the PS3 OFW user.
