Hello, I have an APM 2.8 (2.6 clone), accidentally i broke it's usb. When I tried to resolder it, and when I connected to my pc, it shows not recognized. It's working fine. Can anyone tell me an alternative to usb. I have a Telemetry but when I tried to upload firmware, it shows can't upload. Please help!

Bump

Can you post a pic?

Dude , only the usb is broken.

A damn pic would show if anything else is broken as well. Please post a pic, at least after you've soldered it

apm is basically atmega 2560

findout where the isp headers are and use an avr programmer to flash
the firmware using arduino interface

or flash direct using avrdude ( which the arduino interface also uses)

After I soldered t, It got broken once again. So, I trashed the usb. Will try the above thing.

It's a portraited photo! Nothing that's necessary is visible. Man, you're so great!

As @saikat sir has already mentioned, upload it via the headers.

Also check if you have done any damage by soldering it. Most probable is a short

Is that solder pads is good? I recommend you to join microsoldering group in facebook. Group members of that group will help you in this.
