I've always reset the counter and got rid of the triangle this way:
1)Flash an old bootloader via Odin (u can find it here http://forum.xda-developers.com/show....php?t=1075278)
2)turn the phone off and insert jig
3)Flash ICS bootloader back
Switching between bootloaders can be risky if installation process goes wrong, but I have never had any single issue with that. I've done it several times and it has always worked like a charm. (Doesn't matter if your device came with preinstalled ICS, for example my freshest handset was produced in april this year and thus it came with 4.0.3 by default - The method above still works on it.)
And BTW. I don't think this topic should belong this section.
