Again, if you are not FF FF out everything that follows the 1st $SVS including the $SVS all the way to the area of FF FF FF .... that follows,
then it will not work, nor will you get a boot from the mac. You need to remove it all including that first $SVS.
Again this is based upon you saying

I know how to use Hex editor to remove password after $SVS,


That leads me to believe you are leaving that $SVS untouched & remaining.

OK so we finally finished this one without desoldering chip and using ch341a + chipmunk clip. this programmer reads no problem but erasing and writing back on was a b!t@h. what we had to do is change chip model to COMMON 25*64 with charger plugged in and battery connected we attached clip, choose detect, once detected disconnect battery (charger still plugged in..then erase...confirm erase..and if u can erase then u can write np. Hope this helps someone.
