I have been flying quad out side in really cold whether lately but it seems to handle it pretty good. Recently i bought a New GPS and magnetometer to make my quad much more stable. Anyway after i got my gps i realize that the GPS is neo-6m and i need to do some editing on source to get it running properly. I did my research and finally i started to compile the code using ardino for the first time and i started uploading. Took about half a min and it came up as upload done with few errors. So i thought nothing harmful and i rebooted the APM, no red or blue led are turning on.

Okay, now i thought i might have broke the  code and it just need to reflash using Mission Planner. Well that failed too with no communication error. Then i thought i need to re flash the boot loader. I found isp pin and i plug that into my programmer, that failed too. Now i was bit confused and there is no rx tx lighting up too.

Then i thought, i might have to clean the board and try again since when i bring the quad into the house water get condensed on the unit so I took one of my perfume bottles and start spraying at the board knowing that perfume has alcohol in it and it will help me to clean the board(living in a college house so dont have much tool available). Wala that worked, i was able to re flash the board with the new update firmware. I kept my finger crossed and connected it to my mission planer. Then mission planer started to yell at me gyro health is bad. errrrrr. I was at this point frustrated.

I took a sharp screw driver, tryed cleaning around the MPU-6050 and something cause APM to go into a mood and it flashes a red led like 3 times and goes off. NO communication whats so ever.

Does anyone know what red led flashes means? Should I hot gun MPU and resolder it? I dont have money to buy a new one and i really need help.

I was thinking of getting a membership at near by Maker space so that i can use a hot air gun.
