Hello! I have a problem. I am using MacBook Pro 13 Mid 2017 (Two thunderbolt 3 ports) since 2018 without any problems. I was on Big Sur and decided to clear my MacBook. I rebooted into recovery mode, erased Apple SSD and tried to reinstall Big Sur. But it failed with error like "failed loading update" during installation. In logs there is error saying CRC missmatch. Since then I tried multiple times to create bootable stick with Mac OS installation using another MacBook. Every time I am trying to install Mac OS from stick I get same error in logs: CRC mismatch; got: %number% expected: %number% for file %filename%. I tried Big Sur and Monterey, same error for both. just different files and CRC checksums numbers. However when I create stick with Catalina I can install it successfully, but in logs I see that it also fails to verify CRC but after that it is not failing immediately and tries to retry and retry completes successfully. After that I am able to boot and use my MacBook without any problem but when I try to update to Monterey through system settings during installation I have the same CRC error.
I tried to reset NVRAM, PRAM, no success after reset. Is there something wrong with my MacBook hardware? Or maybe it is bricked firmware? Maybe there is a way to restore firmware on non T2 models? I saw that Apple suggests to restore firmware on T2 Macs using Apple Configurator, but I can not understand how I can restore Mac without T2 chip. Any help please? I can not go to official Apple service in my county right now because of lockdown.
