Hiya

Ah you got Nigel’s off him then.

I think there is a way to do it using the boot loader and a magnet but I don’t know the procedure, hope someone can tell you how to do it.

Yeah - and just managed to figure it out

Needed the old bootloader!

Now just need to find a new battery that isn't extortionately priced! lol...

It's actually one post above your question: https://forum.heinrichsweikamp.com/view ... f=2&t=4071

There are the links to the required bootloader v1 and the instructions on how to use it.

Hi Mattias - Id read that, but seemed only applicable to the V2 bootloader...

I did guess that that the V1 was needed and downloaded that off your website and everything was easy and intuitive.

Re. the battery - do you still supply them? They dont appear on your website and the only place I've found selling them in the UK want over £35 which is staggeringly expensive for an 18500 battery...

Hi,

It's not only the 18500, it's the assembly with the small protection circuit board at the top. We sell these for 39EUR+shipping. If you still have the old battery, you could probably make this by yourself cheaper.

I did try that - does the protection circuit also drop the voltage? When I add that onto the new battery I get 3.88v and the mk2 then only powers on when I connect the usb...
