recovery of macbook pro after os get corrupted

My mac get slow and i made a bootable usb of catalina and tried to install it. After erasing the ssd and strating for the new install, a message pop up saying "the os cannot be installed, it is corrupted". After this, my mac is showing a blinking folder after starting it. I have tried for internet recovery but whenever the progress bar finished, error messaged appears at last. I have tried for the internet recovery for many times but every time appears the same error message. Now what is the solution for my problem? Please help 🙏🙏

Try connecting the laptop directly to your router using an Ethernet cable as this will avoid any possible WiFi issues.


Try an SMC reset and a PRAM reset.


Try rebooting your router.


If you have access to another Mac, then you can create a bootable macOS USB installer:

What is the exact model of your computer? You can get this information by entering your serial number here:

Did you erase the whole physical drive or just the volume such as "Macintosh HD"? While booted into Internet Recovery Mode launch Disk Utility and click on "View" and select "Show All Devices" so that the physical drive appears on the left pane of Disk Utility. Select the physical drive and erase it as GUID partition and APFS (top option). Once erased try reinstalling macOS again.

My mac is macbook pro 13.2 inch 2019 model.

I have erased the voleume "Machintose HD". Internet recovery mode didn't suceed as i have tried for so many times. so disk utility is not able to see. how can i see disk utility if internet recovery fails every time. (internet speed is good enough for the recovery but not getting success. when the progress status finishes in about in 10-12 minutes, then a error appears.)
