hi
if you are just re-flashing to get rid of the analouge function and improve reliability then stick with the dpr chip.

If you want the excellent lights that these chips afford then you need sparrow hawk eyes and superb soldering skills to be able to do it..

If how ever they are lacking like mine then swapping the dpr cars to solder in chips makes things a lot easier,especially if someone is kind enough to do them for you.

Even with Greg's diagram and my glasses on and a magnifier I can't find the right bit, if I could I don't think with my shakes I could solder that small any way . So i will save up and send to the experts

Hey Grunz,

This is what MIH recommends from his site&#8230;

Gently separate the board from the carrier. The board is held on four posts, which are melted onto the board to hold it in place. If necessary, use a craft knife and cut off the melt blobs from the top of the board. DO NOT cut the posts off - you'll need these later to reassemble.

Here's a link to this section of his site, his site is set up with tabs, so you will have to click to upgrading chips, f1 chip.

A sharp scalpel does the trick for me. Try to leave as much behind as possible then you can use the tip of your iron to re-melt the plastic to anchor the board back onto the carrier once you have re-flashed the firmware.

Good luck ......
