This has always worked for me (after going through the same as you).
Behind the ITB motor there is a silver bracket with two silver screws. This bracket affects the tracking of the belt. Remove the ITB motor. Loosen the two screws on the bracket and adjust the bracket 1mm at a time until the belt stops tracking off.
Run the ITBINIT in SRV Mode & check in DISPLAY MODE for Belt tracking closer to '0' - it will never get even close to this number because it too is BS. as there is no Initialization to '0' as such, but perform the above several times (before readjusting) until the belt movement stabalises around a constant number range - eg. 125 - 169 - 146 - 152 etc. Also visually check with the R/H door open for even distance of the Belt on the Roller both ends.
