So, this is what I'd try, if you haven't already:
- In Big Sur, start the 11.1 update.
- At the first reboot, choose "Macintosh HD" entry if you have it - not your normal NVMe entry.
- Take a note of how long it takes - you should see verbose boot log messages for at least a minute or two, and if you can read them they'll talk about moving files or something along those lines.
- If after auto reboot you still have a Macintosh HD entry, choose it again.
- After one or two reboots in total you'd expect the next reboot to only have your normal SSD/NVMe boot entry. If it still says Macintosh HD after two reboots in total, it's likely not working (but still try selecting it one more time)
- When you reach a boot where only your NVMe/SSD entry is listed, choosethat, and you'll get a slow progress bar, possibly with "X minutes remaining", but possibly not (I think mine didn't have it).
- After that you'll be in to the OS, and hopefully on 11.1.
If one of you guys with issues could try that and report back, I'll investigate if necessary. If you try that and you still can't apply the update, then yeah I guess there is still an NVRAM issue. Maybe a new msu-product-url NVRAM key needs to be set, different for each update process.
I tried your suggestion going from 11.0.1 to 11.1 and it worked. Thanks!
My steps using opencore 0.6.4 in verbose mode on my ASRock X299E-ITX/ac board without working NVRAM:
1. start update in Big Sur
2. after first reboot chose the new entry "Macintosh HD" -> then took about 10min with lots of messages
3. after second reboot (had to power off as the reboot was not rebooting properly) chose my usual disk entry as "Macintosh HD" was gone -> some messages -> normal progress indicator that seemed stuck at roughly 10% -> took about an additional 10min
4. i think it rebooted again but am not sure as i left the room briefly
5. Big Sur 11.1 started with usual selection screens (Siri, iCloud etc) as usual after an update
-> working System
