Here’s the final solution to CGDI MB key programmer error: “Load File Failed, error code: 27E1” (shown picture below)
Possible reasons that cause the error:
1). Device fell on the ground and damaged
2). Take apart the CGDI main unit manually
CGDI Prog MB host is equipped with an encrypted battery. If you disassemble the programmer, the encrypted battery will power off automatically. BenzMonster software refuses to run properly.
What is more, the battery cannot be purchased separately nor installed by yourself.
The ONLY solution is to send CGDI back to repair.
Always read CGMB label and directions carefully before beginning use.
