I'm probably an idiot, but I think softbricked my Vita and don't even know why. What I did was (since I wanted to use the PKG installer): 1) Put the Vita into IDU mode (using the HENkaku homebrew). 2) Edit the app.db file, like in this guide. 3) Reboot the Vita. Nothing different. Retried several times. 4) Noticed that the PKG Installer had the value "12" in "page ID" and "1" in "pos", so I thought it would appear if I added enough pages to the home menu. 5) Created 3 or so new pages, moving an icon to the bottom left of each. 6) Rebooted my Vita. And... The PS Logo appeared, the epilepsy warning too, but the little spinning bubbles or whatever froze almost immediatly and the system shut down. I tried to reboot several times, same result. Thinking it was a database problem, I rebooted into Safe Mode, rebuilt the database, but it didn't change anything... Except that now, everytime I power the system on, it rebuilds the database. Is there anything I can do? EDIT: The console boots normally if I start it without the memory card, if that can help identify my problem. EDIT(2): Problem fixed, see below.
