2012 MBP Bricked

Was running macOS Catalina for quite sometime. When Monterey was released the MBP tried to auto-update and the laptop was bricked. Did an internet recovery to Yosemite successfully. Tried to update to Sierra and now in a fail mode. Gets to last step and I get an "error occurred while updating systems extension information". I can't boot, safe boot or do an internet recovery. Every restart, starts the Sierra install all over again with the same negative results.


Any Ideas? Thanks.


Most MacOS downloads seem to bee broken or corrupted for some reason.

MacBook Pro 15″, macOS 10.15
