Another angle: S60v1. S60 has multiple versions, and there's a distinction between UIQ and S60. UIQ is another platform, but S60 is Nokia's. So the user is specifically after Series 60, Version 1. So perhaps looking into old Nokia support sites. They might have had a download section for firmware, but it's no longer available. Maybe through wayback machine? Let me check that.
Looking up "Nokia S60 v1 firmware download" on Wayback Machine. Hmm, maybe some old support pages are archived. Alternatively, user forums like XDA Developers might have threads where people archive ROMs. For example, the XDA forums for S60 devices. Let me think if there's a section there for older S60 versions. s60v1 rom download
Wait, some Nokia models might have firmware updates stored in their support databases. But those would be for later versions. For S60v1, maybe not. Alternatively, user contributions on forums may have extracted firmware files. For example, if a user wanted to get their phone working again and extracted the firmware from their own device, they could share the .nds file. But again, redistributing those could be against the ToS. Another angle: S60v1
