Is Devo 12E supported by the Deviation Uploader? was created by andrej
I got a Devo 12E, installed the 4-in-1 chip and wanted to flash Deviation. The uploader 0.8.0 that otherwise successfully updates my Devo 10 shows Devo 12E as unknown:

Is it feasible to flash the device with the current Deviation Uploader? The uploader refuses to automatically create a filesystem in this case. I assume I could connect it via USB in the mass storage mode after firmware flashing, format the device manually as vfat and populate it from a v5 Devo 10 firmware build, as recommended here . But my assumption may be totally wrong and I definitely wouldn't like to brick this thing. This forum post says that Devo 12E is indeed not supported yet.

I tried to look at the (recommended) Dfuse tool from Walkera, but the archive contains a strange file with a name ending in ".exe". That definitely won't run on any of my systems. Is there perhaps a development build of the Deviation Uploader with Devo 12E support?

Now I'm confused. :-( It looks like Devo 12E is in transmitters.yml! And it has been there for quite a long time already. So, what's wrong with my Devo 12E? Does it have a different ID somewhere that doesn't match? What should I check?

I am pretty sure that I have never had my 12E work with the java uploader. It works fine with my other TXs but I get the same thing you do.

Could you please post the command line output of deviation uploader when connecting a devo 12e? And also the output when running Deviation uploader with command line argument "-l"?

OK, I somehow managed to flash it, albeit in a very crazy way.
  1. Download a spyware VirtualBox appliance from here , 64-bit, version 10, "stable".
  2. Configure the virtual appliance (roughly) like this. (It will definitely work with less CPU and RAM, but my machine has 32 CPUs and 128 GB of RAM, so I don't care that much.)
  3. Configure USB forwarding for the virtual appliance like this:
  4. Start the virtual appliance.
  5. Download the Dfuse USB upgrade tool from here , version 3.0.5 .
  6. Avoid zadig _like_ _the_ _plague_; it won't help in this case. :-( One needs to do the following instead (in the running appliance):
    1. Install the Dfuse USB upgrade tool in the appliance. That will also unpack a suitable driver for the DFU device (see below).
    2. Plug in your Devo in the DFU mode (power on while holding EXT) and wait until it gets connected to the appliance and initialized. It will be called something like COM5, blabla, not working.
    3. Go to Device Manager in the appliance and choose to update the driver for the DFU device manually. Point the driver updater to C:\Program Files (x86)\STMicroelectronics\Software\DfuSe v3.0.5\Bin\Driver\Win8.1\x64
    4. Start the DfuSeDemo application in the appliance. It should see the DFU device now.
  7. Flash the device with the Deviation firmware for Devo 12E from the end of this thread using the tool you installed; for some reason it's called DfuSeDemo. The tool should recognize and display that it's a Devo 12E that you're connecting.
  8. Stop the VirtualBox appliance.
  9. Connect the device in mass storage mode (hold ENT while powering on).
  10. Format the device that appears (happened to be /dev/sdh in my case; check dmesg for yours) as FAT12, e.g. like this: mkfs.vfat -F 12 -n DEVO12E /dev/sdh
  11. Mount /dev/sdh (or whatever device this is on your system) and copy a Devo 10 filesystem into it, either from an existing Devo 10 (my case) or from the v5.0.0 Devo 10 zip image; simply copy the following files from the archive into the new FAT12 filesystem:
  12. Unmount, disconnect, power cycle the Devo 12E and you're good to go.

Hehe, that seems a little overkill on cpu and ram for running dfuse :P
It should probably just have worked with deviation uploader, as it reads the device flash areas correctly. Could you please share the output of lsusb for the devo device?

So I tried to flash the Devo 12e with the Java flasher, but it didn't work. It just says "Copy complete" immediately and does nothing.

BTW, the approach I described above has just bricked my Devo 12e. It worked fine for an initial installation of Deviation, but when I tried to use the same approach to upgrade to the August 1 build, flashing appeared to work, but since then the device only starts in DFU mode, no matter if a button is pressed. If it can do DFU mode and flashing, this is probably reversible somehow, but there doesn't seem to be a tool that could fix it.

EDIT: This can be fixed using the DfuSe USB Upgrade tool (version <3) instead of the DfuSeDemo tool (version >=3). Not sure where the difference is, but the older tool identifies and flashes the Devo 12e just fine.

This confirms the results I got earlier. The only reliable way to flash the Devo 12e is with the DFUse 2.31, as I found here .

The Java Uploader doesn't see the Devo 12e as anything but Unknown, so it is not usable.

The DFUse 3.05 version sees the Devo 12e will allow you to backup the original Walkera Config, Internal and Library images, and they can be reloaded with 2.31. However version 3.05 will not reliably flash the Deviation images.

OK, just ordered a 12E and am going to look into the 4in1 module install and maybe even the voice mod.

I just love Deviation and this group of transmitter hackers.

Any advice for the mods to the 12E? (I have killed one 7E with the infamous pin 13 soldering.....successfully modified 2 others though....LOL)

You don't need to solder to the MCU pin in the 12E, so it's much easier, also plenty of place is in there...

The 4-in-1 soldering on a 12E looks exactly the same as on a 10. Just easily accessible pads on the PCB; no expert skills needed.



Mods that I'd love to see would be Hall effect gimbals, but preferably easy to install, without too much drilling and 3D printing. And an open-source flashing tool that would support the 12E would be very helpful. :blink: So that one doesn't need to start NSA (R) Spyware (TM) in a virtual machine for each Deviation upgrade. :oops:

Deviation Uploader 0.9.0 still doesn't support Devo 12e. :(

One more thing: It looks like the Devo 12e has a bug (which I haven't seen on Devo 10) that makes it impossible to read certain perfectly legitimate states of the FAT12 filesystem.

Once you create the FAT12 filesystem, Devo 12e will not tolerate file replacements or file editing done by mounting it via USB. Your entire filesystem will then become an inconsistent bunch of random characters and presumably, Devo 12e won't boot from it if it gets too bad. It mostly affects the languages/ directory, but also other directories.

The solution is to never overwrite files, not even within one single mount. Simply prepare all your Devo 12e filesystem beforehand, including all the model definitions and all the zip contents highlighted above. Then copy all of it once (wihtout ever overwriting or otherwise replacing / deleting anything on the FAT filesystem) to the Devo 12e, unmount it and don't mount it again, because it seems that even mounting and unmounting the FS a second time turns it into a pile of broken trash.

This is very strange and it doesn't occur on my Devo 10. However, editing and saving models on the Devo 12e works perfectly fine, so internally it doesn't clobber its own filesystem beyond readability. Just the mounts are troublesome.
