BSOS is a 1633S specification firmware (16x CAV/P-CAV +R, 8x Zone-CLV -R, 2.4x +R9)
BS41 is a 1653S specification firmware for 1633S model drives (US market, where it seems they will not be launching the 1653S)
- brings the -R up to 12x P-CAV, and the +R9 up to 4x
Is BS41 better or worse than BS0S ?
- It depends on the drive ... some drive tolerances seem to fit better with 41, others with 0S - with a fully unlocked flasher, you can flash up and down - and the wrong drive too, so take even more care than usual if you are handling an unlocked flasher, or firmware BIN's and LTNFW.
