# Bootloop issue when installing the latest firmware on my new MKS Robin Nano V3.1

(Asked by: username_0 on 2024-09-30)

I've got a new Robin Nano V3.1 (with 5 TMC2209s and a TS35 screen) and I'm trying to update the firmware.

I powered up the board when I got it and everything seemed to be working fine (i.e. the interface was working) and then I tried to upload the latest version of the firmware using a 2GB (FAT) SD Card (newly formatted).

Firmware: <https://github.com/makerbase-mks/MKS-Robin-Nano-V3.X>

I copied the files from the bootloader/Beep folder onto the SD card and inserted it into the board and powered it on.

[![photo of screen during boot](https://i.sstatic.net/zOnKyGc5.jpg)](https://i.sstatic.net/zOnKyGc5.jpg)

The board powers up and says it's updated. The file nano\_v3\_bootloader.bin is renamed to NANO\_V3\_BOOTLOADER.CUR.

But the board is now stuck in a boot loop. The screen flashes (slightly) twice each time it attempts to boot, and on the second flash it beeps.

Did I do something wrong? What do I need to do to put things right?
