PSVITA 3.50 and TN-V Bubble : Only White screen after boot

[Razorbacktrack]

Hi,
Following this tutorial (http://wololo.net/2015/10/11/tutorial-i ... -psp-game/) I used the UNO game as base (but also I tried with Canabalt Minis,that perfectly works with ARK CFW) with my PSVITA 3.50, but every time I start the TN-V Bubble, I only get white screen (also keeping R pressed).
What's the problem?

Make sure you are using the right version of TN V 11 for firmware 3.50. I had the same problem and it turned out to be the fact that I was using the 3.52 version of TN V 11 bubbles and it works a bit different than the 3.50 version. Once I realized this I installed TN V 11 without a problem. I got the right version off of the web since the link on wololo was down when I tried last week. Let me know if you get it to work or if you need the file, I can gladly email it to you. Happy CFWing !!

Same issue running 3.36 and using Numblast as base game. Tried using the 1.00-3.36 files from here and still ended up with only white screen.

Might it have something to do with ARK-2 being installed beforehand?
