Big Sur on Late 2008 MBP stopped to working

Since 2 months ago, I installed Big Sur on my late 2008 MBP, the last week I had to format the ssd for a problem, but now I can't install Big Sur anymore, because when I am on the installer at 15 minutes of finishing the installation says: An error occured loading the update macos, tried to restart and doing first aid on usb and ssd and connectiong to wifi, but I have this error in loop that before there wasn't, tried also to redo the usb and redownload Big Sur installer from Mist but didn't resolved
