I guess it has to be done with calterm5 or older version works 3.17? 4.7?

It's better to connect with new protocol as there are less problems (Calterm 4/5) vs the old block by block protocol (Calterm III). However, Calterm 3.17.0 also will connect usually without problems to most Chrysler ECMs provided you have the correct ECFG's/E2m's.

The unlock can be done right in Calterm if you know how to complete a service command.

I've been exploring the different modes these 2350bs can operate in. I think I'm almost got it, but I'm still experimenting. I kept thinking I'd end up bricking these things kicking these ECM into rom boot, and bootloader too many times. But knowing they can be recovered with different methods is reassuring. Still trying to make sense of all the checksums in these different modes, and the cals. I'm going to feel like an idiot if it's as easy as ticking a couple boxes somewhere in these different modes 

I might just try to scoop a spare 2350b to play with. I'm guessing you can't use a 2350a harness on them, right?
