Error -2100F is very similar to the Error -1008F and other recently spotted errors, such as Error -2106F, Error -1426 and Error Code 1309.

Error -2100F appeared on our radar as a result of a post on Apple Discussions, where victims have complained about the following kinds of problems on their Mac:

Cannot run macOS Recovery (error 1008F-2100F-2003F) -Mac stuck in internet recovery
MacBook Pro Late 2019 started restarting unexpectedly.
So, I decided to erase the disk and run a clean install. Command+R and boom I get a firmware passcode.
I go through and I get the typical options.
I erased the disk through Disk Utility and the only option was Ventura.
I didnt want Ventura, so I switched off in order to restart and be able to re install the previous one I had (Big Sur).
No luck. The mac is stuck in internet recovery mode only, doesnt offer other options after booting. When it gets connected to the wifi, I get errors 1008F. I got once 2100F & 2003F.
I have deactivated Macbook from Find My, I have reset PRAM, SMC etc.
I have tried wifi, wired connection and hotspot over the iphone with 4G (that was the fastest).
I am so desperate. The machine refuses to run a recovery & clean install.
