Thanks for maintaining this index — really helpful.

I'm stuck on the 120P (NSPanel120PB) at v3.4.1, and the earliest verified "from" version on the 120P diff list is 3.5.0. There's no confirmed 3.4.x → 3.5.0 diff link for this channel (nspanel-pro-ver120). Does anyone have a verified URL for that specific hop, or know whether 3.4.1 needs a different path (e.g. via the emergency recovery to an earlier full ROM first)?

Happy to test/verify a candidate link and report back with a curl -I check if someone has one.

I still do not have a confirmed 120P 3.4.1 → 3.5.0 diff. The CDN cannot be listed, so I cannot say that hop exists. The only indexed full-ROM checkpoint is 4.0.12; applying it directly has been verified from 3.7.1, not 3.4.1.

I would not recommend emergency recovery or a downgrade. If your panel is rooted and recoverable and you test 3.4.1 → 4.0.12, please report the result and I’ll add it to the guide.
