Just trying to read LS1B PCM and get the "bootloader locked" pop up. PCM checks out okay. -I was in this PCM in the past with no connectivity issues.

When checking PCM security- it states PCM secured with a custom key. Tried various iterations eg. alt key on, high speed unchecked, 00000, $FFFF, FFFF, 00001 etc..

Updated to latest v7.5.7 build 282 with no luck.

Downloaded zip file from $0333 thread with no luck.

Any foreseeable workarounds?
