Renaming/removing "system_update_plugin.rco" - Impacts?

Post by OperationNT » Sat Jan 14, 2017 2:57 pm

Hello everybody,

I try to have a system which cannot be updated through LiveArea and any application (but which can still be updated through SafeMode in case I mess up with "vs0:").

I noticed that if I rename "vs0:app/NPXS10015/system_update_plugin.rco" to "vs0:app/NPXS10015/system_update_plugin.rco.lock", the update menu in "Settings" application doesn't work anymore and when my PS Vita displays "Update software", the menu which pops when I pick the button is also locked. This is exactly the behavior I was expecting.

I would like to know if someone already tried it and if there is any negative impact (for example, permanent brick risk because SafeMode won't be able to apply an update). Does this method prevent update in IDU mode?

Thank you for your answers!

Well safemode have files to work in os0: If im right so you will be still able to update vita with use of safemode ;)
I did not expect that you can still edit some files in vs0 and be able to accouly get it startup. well i think only some plugin files or .jpg .png .dds files.

HERE i found this >> os0:sm/update_service_sm.self
I think its update service for safemode ;)

Ps. i tried the same as you did and ofc when you get in update options they just change name to "msg_update_wifi" and so on.. and when you enter it nothing happens.

Thank you for your clarification.

Yes, when you enter the update menu, you see string IDs and then, nothing works which is enough to prevent any unwished update :-).

os0:sm/update_service_sm.self is actually a Secure Module (that's what sm stands, certainly not for "Safe Mode", it is therefore used during updating, it doesn't matter if the vsh is involved or not), I would not advise on modifying the system files on a vita, no matter the purpose, it is safer just not to update, unless you are in IDU mode, updates on vita aren't forced on the user.
