There have been several reports of users not being able to use the web applets without updating regardless of FW, DNS settings and several other factors, making it impossible to use the HBL and SwitchbruDNS.
This has now been investigated by devs over at the Reswitched discord and we know the following:
NeedsUpdateVulnerability is a function in the ns:vm service in the NS module.
It seems that in systems with the issue it is set to 1, while "normal" systems have the value 0.
When any of the web applets open they will check that value, if it is set to 1 a update will be needed, this update prompt can't be cleared by going into recovery mode making it impossible to launch the browser, and seems to be a issue on all FW.
We do not yet know how this value was changed, but as the DNS servers don't block all servers it is suspected that Nintendo have made a undocumented server to change this value. (this is speculation) regardless it would be smart to now completely disable internet (airplane mode) until the cause is found. (If you still plan to block updates).
What we do know: This issue is standard on all new Switches shipping on FW 4.1.0+ (see image 2)
Is it patcheble?
Yes, but right now Fusee does not have sdMMC support, so the only way now is to patch it through running Linux on the Switch and then applying a patch from there. Obviously that is not a easy solution, but until more is understood we have to wait.
