  • Resolution set to wontfix
  • Status changed from new to closed

This is intentional to prevent accidentally overwriting/erasing uboot and its settings or the art partition.

If you really need write access build your own image with modifictions (remove .mask_flags = MTD_WRITABLE) or use uboot itself.

I have tried the Barrier Breaker 14.07 and it is the same result.

It is still locked!

You say is to protect "prevent accidentally overwriting..."

Replacing the boot loader with something that do not need the soldering on the tiny, tiny, puny board and damaged it physically...

"Prevent" a disaster! That is exactly what that would achieve. You could have thought of a software switch for instance.

Asking us to build a new image increase drastically the risk you are trying to avoid in a first place.

Now, that being said: Can I change just one module "mtd" instead? That would reduce the risk.

The solution is to build a new image?! That is so stupid. I'm going to fuck up my flash instead and insult people on IRC :D...
