Macbook Pro 16 A2141 stuck in network boot

[sdogs]

Good evening guys ;-) In a moment of lucid madness I bought a macbook pro 16 A2141 on which they sat on it. Aside from the banana shape and obviously gone screen, the macbook turns on, sounds the initial gong.
I disassembled the screen and connected it to an external display, using a usb-c adapter, but I can't reinstall the os.
I tried SMC and PRAM reset but the result doesn't change, the recovery starts only from the network, I tried different USB pendrives with different operating systems but nothing, it sees the boot device for an instant and immediately goes looking for the network.
It goes into taget mode but I don't see the disk from other macbook, it doesn't seem to go into DFU.
The strange thing is that it downloads the operating system from the net, the apple logo appears, the line goes on without errors but when proceeding with the installation of the os. I have no video output.....
I tried booting with linux deft but nothing to do, immediately search the network ....
Any suggestions? I take a big hammer ? ;-)

T2 or M1 macs have full security enabled by default, which means you cannot boot via USB. You need to be able to get into recovery mode first to disable it, but you can only do that if you know the old users password. Wiping/reinstalling has to be done via network and then you might be met with an activation lock.

This is why buying these newer macs is a complete lottery unless you are dealing with the original owner to get rid of the acitvation lock. Bypasses are only available for the T2 mac's but this is hardly useful if you are trying to fix these for re-sale.

hi reformatt ;-)
thanks for the reply but after countless attempts I solved it by pressing cmd+v at startup, it restored via lan and started and now it works fine, was it luck?
I had tried in every way but in verbose mode it did the restore .... mysteries of apple ;-)
