First u need to overwrite the the email app database by using the writer.eml
to do this send writer.eml to ur email then receive it in your pstv or vita then click the image and close the app (dont click the error message)
then re open the email app and setup your email again
now the app is ready to write files ..
so if u want to write a file all u want is to rename that file to
then attach It to the message and write the pathe you want in the subject
for example you can try writing this file to ur0:game/launch/list_launch_vita.dat to bypass the pstv whitelist
fell free to ask
for all who don't know how to send eml to mail
Open writer.eml with Thunderbird
Go to Message -> Edit as new Message (Ctrl + E)
Enter your email and send to device
Also for adding attachment in email (when added right click on it and rename)
Followed the instructions but I’m getting a C2-15413-4 error trying to lauch Uncharted cart on 3.20 PSTV. Tried rebuilding db but no dice?
OK, got it to work but noticed the following,
1. Renaming to ‘x’ didn’t work, I had to use ‘#0’ to get it to show as camera icon.
2. I needed to put a ‘.’ at the end of the subject line ie. ur0:game/launch/list_launch_vita.dat.
3. After clicking the attachment, instead of an error it simply changed the attachment name to ‘done’ and that was it. After closing the email app I was able to launch Uncharted.
4. I couldn’t actually play due to the ‘Touch to Start’ retardedness.
You will need to do it again as resetting the pstv is like getting a brand new system
this exploit does work on the latest vita update
