While you can access user-land exploits on 9.03 via the web browser, these exploits do not grant the kernel access required to modify the system storage or bypass Syscon security checks.
Unless you are comfortable soldering and your last version was 9.00, the best "fix" is to use the newer PPPwn exploit on your current firmware. for your current firmware instead?

Downgrading a PS4 from 9.03 to 9.00 is a highly technical process that involves hardware modification. It is not possible via a simple USB update or software "fix" because Sony's firmware is designed to prevent rolling back to earlier versions. downgrade ps4 903 to 900 fix

Some users have reported that Wee Tools displays 9.03 as "1.62"—this is a known issue but doesn't necessarily mean the tool isn't functional. Check for updates to Wee Tools or consult community forums for workarounds.
