[QUOTE="gdanas87, post: 96046, member: 18198"] First of all, I owe a big big thanks to Doulela!!! Thanks to his help I was able to get my sparkie back in the air again. Let me recap, from the start of the story A month and a half ago I added a used spark to my dji collection (mavic pro, mavic air, phantom 3 advanced, phantom 4 Standard). I know the little spark is not anywhere close to all these drones (video quality-wise) but it has quite a lot of advantages to all of them, one of them being the small form factor and second the fact that it is nowhere close to being annoying and obnoxious to people around you... I only had a chance to fly it 2-3 times (without the rc) before getting the bunny hop problems. It would lose and gain height spontaneously (a thing which drove the motors crazy and made them really really hot), and it once even crashed from about 20-30ft down to the soft grass of a soccer field, thankfully nothing broke... I felt so cheated, since the previous owner never mentioned of this "feature" and I felt even more stupid and unlucky that on the "demo" flight prior to me purchasing it, the problem didn't appear!!! I contacted him about this and he of course knew nothing of this and didn't want to have anything to do with me... I decided to try to refresh the firmware -to no avail - and the bunny hop persisted. I used the DJI assistant for this. Then I used another 3rd party open source software and downgraded (a tool I have used many times with my mavic for various mods) in hopes of getting it fixed... Nothing!!! Still the problem persisted! Things only got worse and sparkie was bricked after having an update to the most recent firmware stuck at 57%, hilariously enough while using DJI Assistant 2 (and not the "shady" open source tool)!!! Through all these troubles, I only had a chance to fly it twice, and even worse than that, I had already invested on a controller which was now on its way to me in the mail... Oh man what a bummer... Such a bad experience! Thankfully, user doulela read my story here and sent me his crashed spark for a really really low price to use the mainboard from. I transplanted the mainboard to my spark and wow it works and flies again!!! My gimbal stays tilted a bit (an issue that was not present with the original mainboard which is now bricked) and I had to use the adjust gimbal option to get it a bit straight since the 3 succesful imu calibrations didn't fix it, but other than that spark is all is good (for now).

I want to thank doulela once again and I am happy that there's still good trust between good people in this world, and thanks to this forum and him I am now (once again) a happy spark owner!!! Looking back on the whole ordeal, I am starting to believe that my spark's original mainboard (or a part on it) was on its "way out" since I strongly believe the hopping issue and the way it so easily got bricked were connected.

Oh well, the bricked mainboard will now rest in my desk's drawer and if anyone needs it for testing or perhaps any good electronics components from it they can have it!!! happy flying to all PS. I have only two questions which I am sure have probably been answered many times on sparkpilots but I chose to attach it to this post anyhow, so I will remove them from here if that violates the rules. question: Is it normal for the spark to get warm during battery charging through the usb port?
