COS doesn't work that way with LS-1B PCM. Read the COS 2/3 Bar OS Upgrade tutorial - it would have downloaded with the EFILive software.

Thanks!

I was confused at the first part of the tutorial and was hung up trying to find the upgrade listed under "upgrade OS".

(ive seen it in the list before but apparently like you said not on the ls1) regardless I was able to figure out the COS is in a sub folder when going into the actual efilive program folder and not through a desktop link like I usually open the tunes.

Did you find 02020003.tun and/or 020200005.tun...?


Also, see some COS notes here: COS5.txt

( that applies mostly to COS5, but some of it also applies to COS3 )


Follow the LS1B COS tutorial (full flash, cal flash, fix all OOR tables, fix B3647/9, cal flash, read back, save to file).

I did see both but I didn't go any further than that. I will take a look at the COS5.txt and take baby steps from there.
