ok, so i found a way to get rid of the custon sofware warning triangle.
totally on accident... but still i deserve some credit i think.
all you have to do is:
after the custom install (using odin, usually needed after updating to 2.36 and trying to revert to 2.3.4)
install CWM
do a nandroid
install the stock 2.36 update from Samsung
install CWM
restore your nandroid., making sure to wipe dalvick and cache
Voila!

The triangle no longer loads.
hope this helps some people. i wonder if the GSII has a stock rom they can install from samsung and do the same... anybody have one and wanna check?
