Yeah I know that as well

The issue is if I go s on for repairs now on hboot 1.56 I will get a **TAMPER DETECTED** message and need to unlock via HTC dev again

If I NEED s on I can downgrade the hboot to 1.44, install an earlier 1.29.xxx.x Rom and return to S-on and accept OTA's til latest version

So it's either send it off now as is and hope for the best or just suck it up and go back to s-on
