Fireware Update failed V2.0.19

Reis · Saturday at 4:43 PM

Hello Everyone,

I'm trying to update my Evo Lite+ to the latest firmware version V2.0.19. I've read that some users are choosing to skip this update, but on iOS, the app doesn’t allow me to fly without updating.

I've used a new, compatible SD card formatted via the Autel Sky app. However, every time I attempt the update, I receive the following error:

"Upgrade failed. Please restart the vehicle and remote controller to try again."

Both the controller and the aircraft are fully charged during each attempt. I've also tried multiple SD cards—all compatible and formatted through the app—but the issue persists. I wish there were a way to bypass the update since the drone was working perfectly before.

My current app and firmware versions are:

iOS App Version: V1.7.36 (202501012040)
Aircraft Firmware: V1.9.9

I’ve read that it might be possible to manually update both the controller and aircraft by downloading the firmware to the SD card. Unfortunately, I can’t seem to find the latest firmware file on the Autel website.

I’d really appreciate any help or guidance you can offer.

Thanks, everyone!

Go to the Nano forum, updating firmware.

All battery fully charged.
Are you connected to the internet?
Did you try with another hotspot?

Xin chào các anh chị e đang sự dụng autel lite plus. Có cách nào để hạ phần mềm của lite plus về lại phần mềm cũ cho autel lite plus không. Và pin điều khiển trên tay cầm autel lite plus khá là yếu và nhanh hết pin. Tôi muốn thay thế nó bằng pin khác vậy có cách nào để thay thế nó không ?

I translated with my phone. It depends on what version of firmware you have to start with. There is a lot of current info under the Nano plus forum. I don't know anything about changing the battery in the controller.

Tôi dịch bằng điện thoại của mình. Tùy thuộc vào phiên bản phần mềm bạn phải bắt đầu. Có rất nhiều thông tin hiện tại trong diễn đàn Nano plus. Tôi không biết gì về việc thay pin trong bộ điều
