Has any one got a link or have the file go.apk 2.6.0? As i have a friend that has upgraded to 2.6.1 but he has batteries that are now made by DJI and he says the app does not allow take off as it says they are not dji batteries. I find this strange as the app does not have anything to do with take off ect and he has not upgraded any firmware.. maybe the app just refuses to work. I will speak to him later to find out what is what but just warning anyone who has any batteries not made by DJI until someone finds out if their is a problem. Dont affect me as i use ios and would never use cheap copied unofficial l non dji items that have anything to do with flight or control woops think i just posted in wrong area, can it be moved admin?
