any tool for avoid a new system update?

[hardlevel]

I made the downgraden from 3.74 to 3.65, but after instaled the itls, the sysrem rebooted and asked for the updated, I couldn't use my memory card until the console is again in 3.74, so I had to do everything again

there's some function or anything else to do for the new updates not showing anymore?

During taihen install, VitaDeploy's henkaku_config.bin's spoofed version should contain the latest firmware version. It currently does not, will fix.
