PS Vita firmware 3.50, TN-V11 eCFW and reasons to not update!
A few days ago Qwikrazor has leaked a TN-V11 eCFW build that is working on PS Vita firmwares 3.3x, and can be modified to work on firmware 3.50 as well.
Even though ARK-2 & TN-V11 are compatible with PS Vita firmware 3.50, I strongly recommend you folks to not install PS Vita firmware 3.50… Not yet.
You might ask why, but one of the reasons are the Custom Bubbles.
Custom Bubbles are patched as of firmware 3.50, and there is no chance of fixing the known technique. It would require a completely different method for firmware 3.50 Custom Bubbles.
Another reason is clearly that firmware 3.50 (same as 3.3x) lacks support for the TN-X eCFW (so pretty much the PSOne Loader), the Package Installer and the Webkit Exploit.
If your device is already running version 3.3x, then I would still not update to firmware 3.50, simply because firmware 3.50 added a few new limitations.
If you are using the World of Pool, Pool Hall Pro or Ape Escape: On the Loose exploits, then be sure to use them on 3.36, since using those on 3.50 will have the above mentioned limitations.
Those limitations are not (yet) circumventable, which means that you have no chance of getting rid of them (as of now).
Those limitations include being unable to properly access the /PSP/GAME/ directory (read-only), which prevents you from creating folders & modifying files in said directory.
Another limitation is that you are unable to rename, delete or even add EBOOT.PBP & PBOOT.PBP files. If such a file is on your PS Vita, then it will stay on the PS Vita. You can not get rid of it, at least not easily.
In the past there have been methods to get rid of similar limitations, for example by renaming folders or using dots. As of firmware 3.50 those methods don’t work anymore, and unless someone finds a new method, this won’t change.
