Lost my M2 Pro with DH- weird speed limit descend

[cmunozs]

Hi all!
Sorry if this has been discussed but I could not find any info about this specific issue.

I have been flying my Mavic 2 Pro for a few years now, with the hack installed. I have used the hack several times doing this very same thing and for the time ever, this has happened to me. I was flying my drone around 2.3KM in a straight line up while I was standing. I had 31% of battery left, which is usually enough to come back down at that altitude, but I must admit I normally do not come down with 30%, but 40% when flying this high. And trust me, I have done it many times. The thing is, per some reason I started to descend the drone and I noticed my speed was limited to 3m/s. Normal descent speed is around 8.4m/s (meters per second), since I changed that with the hack. Long story short, I was able to descend until I was a 150 meters from the ground, with 0% battery left when the dron lost power while in the air and fell into some trees. I might be able to recover it.

Question is: does anyone know why this could happen? Is there anything am I missing here? I know I am pushing the drone for what his purpose was intended for, but In this case, I do not see why this happened due to the hack itself.
It is a very specific question to all of you that have a drone with a modified firmware on it, I guess.
Thanks!

I'm sorry to hear about you crash. I hope you'll be able to recover it ok.

It can be baffling when a drone goes AWOL while following a path that it had flown without incident in the past. Since your Mavic 2 Pro was close to the ground when you lost signal, the "Find my Drone" feature in DJI Go4 should lead you to within 50 strides of the crash-landing site. To this day I haven't a clue why my first Mavic 1 Pro vanished into the horizon never to be seen again a year ago while out on a 9-mile round-trip Litchi waypoint mission. I can only speculate that sudden battery failure might be the culprit in that disappearance.

In my neck of the woods out in the Third World boondocks, FAA and CAA rules don't apply, and that means I can launch my Mavic 1 Pro and Mavic 2 Pro quadcopters on Litchi waypoint missions covering over 13 miles round trip, thanks to the non-DJI extra-range "hump-back" batteries I buy from Ali Express.

Starting with a few spiral-ascent test flights to generate battery durability data at 26 mph cruise speeds, I progress to sending the drones off on more daring cross-country sorties that probe the performance envelope of those batteries when smart RTH is de-selected, and all power-draining obstacle avoidance sensors fully calibrated but disabled.

Keep us updated when you finally retrieve that Mavic 2 Pro, my all-time favorite DJI drone bar none. I currently own two Mavic 2 Pros and one Mavic 2 Zoom, whose thumb-wheel zoom feature is the coolest ever feature.

Thanks for your words! Yeah, I have one of those "hump-back" batteries you mentioned. I have actually been using almost always with my now lost drone. This time, I was using one of the original batteries, which makes me think it was something related to a voltage issue on this original battery. It was recently charged, so it should not be bad charging, but age of the battery itself, I think.
I'll try to find the drone tomorrow during daylight (this happened while the sun was setting). I have a pretty good idea of where it is, but It would be very difficult to get it from those trees o even walk around the area. We'll see...
Of course, after this already had happened, I started to think on what else I could do to make it come down faster. I didn't try sports mode Maybe that could have helped to take the drone out of that "state".
