Officially, they don't. Google updates the FRP mechanism every few months (Android 14 introduced hardware-backed locks that are nearly impossible to bypass via software). However, repair shops need these tools. It is cheaper for a shop to pay $10/month for a licensed tool (like Chimera or Octoplus) than to refuse service to a customer who lost their receipt.
If you answered yes to all four, go ahead. If not, stick to paid professional software or visit a local repair shop. gsmoneinfo o androidfrp verified
