option -oo is recommended standard operating procedure for now. There's no 
particular advantage in trying to use firmware-bootloader first.

Others did.

This doesn't exactly explain anything. For relation of SoC GPIO-b7 and and PMU 
GPIO2 see discussion of gsm sysfs node fix in [hw].
If you were lucky to successfully flash without using "s3c24xx-gpio b7=0" you 
probably used a recent kernel with sysfs node fix.
Anyway not following the quite accurate and detailed instructions on 
gsm/flashing might explain why you didn't see any success on "the other 
combinations"
