This problem is a chronic problem of DJI MINI 1, MINI 2 and MINI 3. (ALL HAVE THIS DEFECT)
I was a victim of "this" defective firmware.
It actually works like this: Dones 1, 2 and 3 DO NOT have a cooling fan. If the update takes a long time, more than 8 minutes, it may cause the 5.8 GHZ chipset to burn out.
This information should be mentioned in the equipment manual and even in the DJI FLY informing to perform the firmware update ONLY on cold days or in places with a lot of ventilation.
Even recommending the use of mechanical winds to help cool the equipment during the update.
In Brazil some companies manage to change this chipset. DJI's recommendation (support) is to change the coreboard (motherboard.)
This amateur error (hidden defect) should be treated with respect for the customer. If you search the internet, you will see MANY people reporting the same defect. DJI Forum, MAVIC PILOTS Forum, Youtube.
Just put "DJI 5.8 GHZ stop work" and you will see several complaints.
I bought my drone at BESTBUY in Canada in November 2022 and I came to Brazil. I received the update 01.06.0200 and performed the update in the living room at home. Since then, the 5.8 GHZ has never worked again.
I opened a call at DJI Brasil and they informed me that I should send my drone to Canada for analysis and they forwarded my call to DJI Los Angeles.
Since then I've been exchanging messages with DUKE (DJI support team employee) and so far no solution.
It is absurd for a product to be sold with such a basic error that a simple message on DJI FLY would solve it.
I am very disappointed with the quality of DJI products and the lack of support.
It explains why the guarantee is not global! (ugh)
