Yes, it is possible to solder the Flex Ribbon Cable for Zenmuse H3-3D. I have done so on five different spots on mine. Tools: ------- Magnifier or even better, some glasses with a lot of + Scalpel with very thin tip Thin soldering iron tip. Thin solder...THIN How to: ---------- You may be forced to first take the gimbal apart. Check howto with YouTube first. Plug in the iron. If possible, start with as low temperature as possible. Try on the solder first. Locate the broken spot. Carefully scratch approx 1.5 mm of both sides. Carefully! until the copper is not covered . Put a tiny amounth of solder on both copper ends, put some very small amounth of solder on the clean soldering iron tip. CLEAN...ok? Then carefully drag the iron over the broken spot. Don't move anything for some seconds. Voila! Connected! If you are unlucky you may have to do this on all leads and maybe on several broken spots. This was the case for me. I know it works because my P2 has been up n flying a lot since the repair.
