I'm trying to get back to the V2_508 no timing firmware or even the V1_508 no timing. I currently have the V3_508 flashed to my Xtreme stock and for the life of me cant get back to the old firmware.

I want to do this because I remember the brakes in the older 508 firmware being much better.

I have uninstalled the V3.1 software and installed the V1.64 software and when trying to flash the esc with older 508 firmware its simply not there. All tha'ts available for me to downgrade to other then the current V3_508 is the V1_508_rev which is the reverse motor direction firmware.

I assumed maybe since the LCD box had the V1.08XXXX firmware on it from the V3.1 software I maybe needed to downgrade the LCD before being able to downgrade the esc. But when attempting to downgrade the LCD box from anything other then the v1.08XXXX firmware with the v1.64 software I get an error message from the software that this cant be done.

Any help with this would be great.

Thanks.

Hopefully I don't have to go out and buy another lcd box and bin the one I have.

Cheers

If once upgraded the box to V1.08, you can't go back I believe.

If you have another box with V1.07 on it, you can still go anyway you want.

I don't know the older available ESC firmwares in V3.1 software, but the following steps should work I think:

With 3.1 software, and V1.08 box, flash the ESC to 930STOCK (or any firmware you know also exists in V1.64), then with 1.64 software and v1.07 box, flash the ESC to V2_508 no timing.

Note:
You can have both V3.1 and V1.64 (there are a few) and V1.63, 1.62, next to eachother on your PC, just unpack them in different folders!

Why bin it?
And also buying a 2nd box should not be a real problem, because they are not that expensive (Checked the box from Orion? :sneaky: )

I won't bin it, use it as a door stop - yes. :rolleyes:

Awesome post an explanation. This is what I thought was going on. Glad you could confirm this. So glad to know it wasn't me and I'm not going crazy.

I do have another LCD box that I got from a friend I haven't checked what he has it flashed with yet. I'll look into that latter.

But what would be best of all would be if Hobbywing would just fix the breaks or allow the downgrading to the older versions.

If I must get another LCD box I will but kinda lame if that's the only fix for this issue.

It would be great if this new software/firmware release Angelo just spoke of would address some of this.

Maybe it time to get this info out. If you upgrade your LCD box to 1.08 you will not be able to go back to the old firmwares in the v1.64 software UPGRADE AT YOUR OWN RISK! . Was this ever mentioned by anyone in this thread?
