I was just breeding "food for thought" because of that user on the other forum that did not delete GUPDATE.GCD as per your instructions.
Another issue. If I use LDR.BIN from the memory card version 5.8 on a 1300 running 6.00 after completion in the inventory screen it shows me.
Boot BLK xxxxxxx 5.80
X-Loader xxxxxxx 5.80
System xxxxxxxx 6.00
This tells me that using LDR.BIN from the Memory Card actually reflashes the Boot BLK and X-Loader.
Is this assumption correct ?
