Error 9
Due to asr being patched, the SHA signature is automatically changed and after being resigned the kernel will refuse to use it. Therefore proper kernel patches are required. If necessary kernel patches are not applied, it will fail to load asr and error 9 would occur during restore.
Rebooting your PC may resolve this issue. Aslo it can be connection issue. CPU/NAND/EEPROM

Try these steps:
Install the latest version of iTunes.
Force your device to restart: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then, press and hold the Side button until you see the Apple logo.
Connect your device to your computer using a USB cable.
When iTunes asks you to update or restore, click Update (not Restore) to reinstall iOS and keep your personal data.
