Evo 2 Pro V2 :Firmware Upgrade V2.3.23 failure on two new drones

[perryfromabove]

I realize that Autel firmware upgrade process can be a little clunky. Then I'm also thinking what are the odds that 3 units have failed to successfully upgrade? Before I left the workforce, quite a bit of time was spent pitching in at the IT help desk. I understand that keyboard troubleshooting can be challenging... which leads me to wonder (with no disrespect intended) whether the firmware upgrade sequence performed is lacking critical detail ? It's unfortunate that we don't have the benefit from a step-by-step recording of the upgrade being attempted. At least it would affirmatively rule out another possibility....or help refocus along another path the troubleshooting flow chart.

sd card, downloaded the right firmware file, placed it in the root and the power RC first and drone second. it fails immediately

this happens if I do with the app

You know that you have to open the file “Model-c….” And will be 4 items that you have to copy those items to the sdcard. No the files.

I asked Autel and they said I need to copy the folder, what you are saying is I need to copy the individual files?

 

[perryfromabove]

but yeah, I know there are 4 files inside

Exactly… if you copy the folder into the sdcard it won’t work.

Yes, you should copy those files to the sdcard and then insert the card into the drone and when you turn the drone and the remote will do it automatically

thank you man !!let me try, fingers crossed

IT'S WORKING. I literally showed the screenshot of the folder to Autel asking the same question. disappointing that they couldn't think of something like this.

just so I am clear, I have another 2 batteries.

i am not formatting sd card and then copy the files again for each battery? correct?

once it's done for all three, I can insert a different sd card because the firmware is already in place?

You got it ! Yes, you have to run the firmware for each battery then the second battery you will have to copy the files again as you did in the first battery because after the update the drone erase it. You don’t have to format each time, it is up to you. After that you are done, just make sure all the parts are updated, (I mean video/camera/battery/ ) look at the Autel website firmware table if all the parameters are updated. After each firmware update I usually do IMU calibration/ gimbal and compass.

amazing thank you, you are a legend

No problem at all ! Glad I was able to help! Flight safe and be safe

 

[perryfromabove]

NEVER MIND - so I did the upgrade it says reboot - when I do it disconnects and says upgrade failed

 

[perryfromabove]

now one battery works but others are having issues, that's a real mess

a second battery it's stuck at 99% for like 10 mins - don't want to touch it but don't think t's normal

I think it is failing as the new firmware is already there on the drone. You should not have to upgrade the Firmware for the drone to upgrade a battery firmware. Is it possible there is a separate file for batteries? In the new firmware zip folder is there a file for the battery

Oh this happened to me as well. But I just turn off the drone as Ken told me will be fine. I just got back home from flying my drone. I flew 3 batteries without any issues.

I don’t think so. Just check on the settings if the battery is updated. If is updated, you are done.
