Can't Bind RX1002 with DEVO F12E TX

Recently I bougth two RX1002 for my DIY drones.
One I bind it with no issues using the procedure:
- Put Bind Plug in BAT of the RX
- Power ON RX (Red Led light's slowly)
- Power OFF RX and remove the Bind Plug
- Power ON RX (Red Led light's fast)
- Power ON TX F12E with Fixed ID (OFF)
- Red Led on RX turns solid (bind complete)

The Second Receiver RX1002 does the following:
- Put Bind Plug in BAT of the RX
- Power ON RX (Red Led light's slowly)
- Power OFF RX and remove the Bind Plug
- Power ON RX (Red Led light's fast)
- Power ON TX F12E with Fixed ID (OFF)
- Red Led on RX keeps flashing fast (no bind)

I've tried several combinations of this procedure but nothing Works.
Do you have some idias to help me? Thank you

Thank you for your advice but that's what I did with no sucess.
The Red Led does not go solid. It keep's flashing quickly. No bind.
It's very strange, the Rx seems to work fine until the binding part.

I did all that like I said in the first post, but the problem remains:
- Put Bind Plug in BAT of the RX, Power ON RX (Red Led light's slowly) = cleared fixed id
- Power OFF RX and remove the Bind Plug
- Power ON RX (Red Led light's quickly)
- Power ON TX F12E with Fixed ID (OFF)
- Red Led continue to flash quickly, never bind

I don't have more ideas.
Can the receiver his faulty? it's brand new...

1º - I'm not certain but I would say about twice per second
2º - Yes, I let it slowly flash for about 1/2 minute (just did it again to be sure, but the result is the same)
3º - In the F12E menus I did the following:
- Model Menu - Fixed ID - Status Off
Then I power OFF the transmitter and back ON to bind

Sorry but I don't have that menu in my transmitter.
What I have is the menus in the attached photos.
So I don't have any way to know if the Fixed ID is really NONE.

Forgot to mention that my Firmware is:
Hardware Ver. 1.2
Software Ver. 1.5A

Done, but the problem remains, although the RX red LED starts to flash slowly as if he had the bind Plug connected

I've tried to install several Firmwares from deVention (Nightly Builds) but it was stuck all the time after flashing with a message USB "something" I don't recall.
Any way I don't think the Binding problem of this receiver is not the transmitter because it works fine with all the other receivers

I've just tried to upgrade the latest deVention Firmware on F12E but it gave me the same error (attached photo).
20170115 deviation-devof12e-v5.0.0-f590316

Well it's Deviation, not deVention.

Anyway: Now you need to,put the file system on your tx. Should show up as an USB flash drive while connected. Then just copy the files on it (or is it devo.fs for F12e also?). should be contained in the deviation .zip file.

You are right. I already reinstall the 1.5A firmware.
Can you send me a link to download the latest DEVENTION firmware to F12E ?

If you copy the devo.fs file from your pc via USB to your f12e deviation starts your tx
I had the same problem after installing deviation but now I am able to work with

Thank you for your tip, but unfortunately when I connect the F12E to the PC (USB) normal mode, or in DFU mode, it doesn't appear in the PC explorer devices, although it appears in MANAGE DEVICE / USB CONTROLLERS / STM Device in DFU Mode
How did you copy the devo.fs to the F12E ?

Ok try this:

Download usb-driver changer (this one which changes from Walkara-Dfuse mode to Deviaton-downloader mode.

Restart every time your PC after changing drivers.

And Install Deviaton with all "enabled".

The f12E in usb mode must be detected as a small usb-drive.

You cant damage - you always can go back to the Walkera-firmware

If the F12E - drive is not detected - there is something wrong with your PC.

I will try to guide your installation - i have done 2 weeks ago - and after 2 nights its running
