2. cause i know that's danger to play with bootloaders, and that can't be downgraded from higher to lower version, once we updated it...

1. I answered with what you asked for, any bootloader. Since you wanted specifics, a better way to ask might have been "What is a good safe b/l that will support SDHC cards in a GO 300?"
2. O yes you can downgrade from a higher to a lower b/l.

1. The answer involves secure bootloader, you're not someone recommend an insecure bootloader, I do not see the logic in your conclusions!

2. No, you can't downgrade, it's not true, it's related only to some custom bootloader, read bellow,

Excuse me here for a bit, but
1. would have been answered if you'd bother checking the tutorial about bootloader
2. if you have no idea what you are talking about you should not state that we won't tell the truth here!!

The fact is there are several BL to choose from with SDHC support, and the next fact is that downgrading a bootload is no problem at all and that it works just fine, otherwise we would not make that statement.
The stuff you link to is about 3 years old and much older for Opentom, if you seek totally outdated information I suggest to do your futher research there instead in our forum where we won't tell you the truth about bootloaders ;)

1. I have no idea what you are trying to say here!!!!
2. "O yes you can downgrade from a higher to a lower b/l." This statement is based on what can be done in 2013, not what could or couldn't be done 3+ years ago!!

oke, but still the question remqins, what is the best bootloader and navcore for the go 300? cause i'm having the same question as i'm a bit affraid of trying as it is not my own tomtom...

The BEST navcore & bootloader for a device is always the current official navcore for that device.

That having been said, take your choise in post 1 of this thread & expect some features being non-functioning.
