If you can't get DFU mode (firmware upgrade mode, EXT + Power On), probably you damaged bootloader.

1) You need bootloader file for Devo F12E - "devof12ebootloader.bin"
www.deviationtx.com/downloads-new/catego...nsmitter-bootloaders

2) You need flash bootloader. I don't know how do it with Devo F12E, but for Devo 7e:
silpstream.com/103/ultimate7e-flashing-the-bootloader/
www.deviationtx.com/forum/6-general-disc...-7e-bootloader#34250

connect "RESET" on the Tx to pin 15 (NRST) on the stlink
connect "TMS" on the Tx to pin 7 (TMS) on the stlink
connect "TCK" on the Tx to pin 9 (TCK) on the stlink
connect "GND" on the Tx to pin 20 (GND) on the stlink
connect "Vdd" (3.3V) on the Tx to pin 1 (Vcc) on the stlink

connect MCU BOOT0 (pin 94) to 3.3V (with 1K resistor, first check if pin 94 is not connected to GND).

For the 10pin st-link the connections are:
tms > swdio
tck > swclk
gnd > gnd
vdd > 3.3V

Be sure not to use the st-link 5V line as it will damage the mcu

devo I succeeded in Dfuse. then I flash with firmware v.5.0.0-ac7f63e using the Dfuse 2.31 upgrade tool & found a problem. the monitor screen is just written "Deviation USB".
I was curious to try to flash again with the dfuse 3.0.5 upgrade tool. "Upgrade Program" without having to restore the button.

what should I do to move to a normal position.
Please help


as i know this is normal you have only to format the usb and copy the "rest" to the drive

Yes, I returned it to normal. I re-flash with dfuse 2.31 & firmware 1.5A.
Can I still reinstall the firmware so that it can support the 4in1 module. which version of firmware & nightly build to make installation easy using dfuse 2.31 without any failure on the screen, only "Deviation USB" appears.

You can't format Devo D12E USB drive, it has fixed format.

After flashing Deviation firmware with Dfuse 2.31, reboot transmitter, you will get "Deviation USB" screen, then copy to transmitter USB drive "devo.fs" file from firmware archive and reboot transmitter. Without this file you will always get "Deviation USB".

It seems that there is already a "devo.fs" file. reads on a computer / laptop in drive G. & After I reboot it still says USB deviation on the screen.

Do you try to rewrite this file? It can be damaged or empty. Try rewrite USB drive "devo.fs" file with "devo.fs" file from firmware archive.

thank you very much, I was able to replace the firmware with nightly build v.5 by deleting the devo.fs file on the usb drive & replacing it with the existing devo.fs file in the firmware folder after extracting.

I will try to connect with eachine e011 & other receivers that support the 4in1 module.

if there is a problem I will give news here.

You will need "BuildFS.exe" to extract, edit "hardware.ini" and create a new devo.fs:

Usage of buildfs.exe is inside buildfs.zip file:

How to use ?
is there any ready-made firmware without having to change existing files such as "hardware.ini" to be able to connect all receivers in this 4in1 module.

I tried it but none of them can connect with my devo F12E which has installed the 4in1 module with firmware nightly build V.5.0.0
