I imported a Toukiden Vita 1000 from Japan last week. Decided to check out the hacking stuff for this device before I just straight upgrade it to latest. Came with 2.12. Using my PS3 I was able to link and activate my vita on my PSN account. Wanted to do the mail bug to create the TN-V bubble. Got a cheap PSP game to sacrifice, got everything downloaded and transferred to the vita just fine. but then realized I needed 3.0+ for the mail bug. So I upgraded to 3.18 using this guide and download. http://www.guidingtech.com/42173/offline-update-ps-vita-firmware/ http://drivers.softpedia.com/get/FIRMWARE/Sony/Sony-PlayStation-Vita-Firmware-318.shtml Upgrade seemed to go fine, but when I follow this guide http://hackinformer.com/PlayStationGuide/PSV/tutorials/how_to_fix_questionmark_bug_for_mailhax.html It doesn't work as indicated. I open the attachment, get the error, close the mail app (home button and swipe) and relaunch it. But the email is not reset, and when I go to #0 attachment its a ? Not sure what I am doing wrong. Is this even worth it? I read somewhere once you get the bubble installed you can update, is that true? Or should I just update to latest and play PSP games on my PSP3000 (which I still have with CFW on it). EDIT: Also openCMA and qCMA are no longer connecting to the content manager. Gives the error "You must update the system software of the PS Vita system." when connecting to qCMA and "Could not connect to the PC" to openCMA. Airplane mode is active. System info says firmware is 3.18 yet I can't do anything like it is. EDIT2: Fixed the openCMA issue. Uninstalled the driver installed by qCMA.
