Hello everyone, I bought my p4 in october 2016 and has been crash and damage free. Last month, however, I started to get vision sensor errors and at the sane time of the errors, got unknown version for aircraft. This was out of nowhere. I am on the latest version of all. It did not start doing it after i installed the latest version either. Just started one day. I tried turning it on and off many times, I used assistant 2 program to calibrate vision sensors and it did it ones, then all the errors went away, but after turning it off and on again, all errors came back. Tried to downgrade a version, was able to do it once. Then, same issue. Off and on .all came back. After that, i tried many many times to calibrate the sensors with the program, tried to upgrade the latest version, but no luck at all. It kept saying restart your aircraft to upgrade or restart to calibrate. No success at the end. I did tried to imu calibration. Still no help.
At the end, i decided to contact. Dji. They told me not to fly it with unknown version and send it in. I did. And after a week they receiving it, they sent me this email!

I didn't understand what all these items have anything to do with my unknown version error problem.it seems like they just want to change couple things and stick 2 hours standart labor and call it a day. And when I get it back, I'm gonna see the same error messages and unknown version issue as i think something is wrong internally with computer inside. As couple times those errors went away for short time and came back by just sitting on the table. I have never crashed, damaged or played with my drone as it is in mint condition even without a scratch.
So, i contacted dji again asked them what is the result and what is $168 for. Is that gonna fix my problem. The guy said " tech support didn't find any issues or malfunction with your drone " ????? What?
I was really mad as it seemed like they didn't even looked at my problem and try to charge me stuff that i do not need as i know my drone is in perfect condition.
So i asked them to check it again ans I'm not paying $168 for nothing and continue having my original problems once I get my drone back. He said he requested a flight records analysis and dispute invoice.
They will get back to me in couple days he said.
So, what you guys think? You guys are more experienced and know more about the product and the company. Am I being suckered into paying without solving my original problem? Or this is the way they work?
Any suggestions would be greatly appreciated. It's just very frustrating when i didn't cause any of these. Why do I have to pay? Isn't there one yearwarranty for defective units? Please help. Thanks.
