GPEC2A Unlock Checksum

1
Hello People of MHH Auto, I am seeking help on getting a GPEC2A unlock checksum corrected. The issue I am having is the hp tuners file makes it past the write file but when I have to key off for 10 seconds and key back on it shows (Writer Transfer Exit: Invalid Checksum) Can someone help correct this please? I can send file read using DC706.
