i don't understand what it is that you are trying to do

do you want to install deviation 4.0.1?

do you want to install the original walkera devention?

list the steps you have taken to try and do what you are wanting one by one.

also why do you think there is a problem inside the transmitter?

Yes friend!!

hello friend, thanks for answering, already tried to install the 4.0.1 version my radio, but he's a blue screen every time I turn, now when I try to install the factory firmware, it gets black lcd no light, and only with a light from power on (red light). The only firmware that it works and I have access to the software and the USB mode to copy the files to the root system, the deviation is 3.0 firmware only one that works on my radio, all others fail ....
I opened the radio to see if he had any electronics problem component, all measures are all no problem ...

If a v3.0 works on your tx, all deviation versions should, and also the stock fw too...

Hello friend it on the site walkera pro 12s you only 2 models a version for the 100mw and 10mw for another B, already tried both, same symptom so the radio turns on and gets the red LED on the battery it is 100% charged, already tried other USB ports, another computer with windows xp, installed the manual drive and also did not work ... I do everything according to the manual first install the firmware, then the libray file and yet when tenteo call it, nothing appears on the screen, no light on LCD ...

What I am failing to understand is that if I download and install the 3.0 bypass it all works, if I try to install the 4.0 deviation, ja my radio does not go over the USB mode to copy the files to the root system. .. simply gives a blue screen ... When I try to install the factory firmware, downloaded by the Walkera site, or blue screen is simply not turn on the light only red light on power connecting. I downgrade to the version 3.0 standard deviation works ...

Hello friends, I did a test now here on my radio, I'll tell you what I did ...
1st pass the firmware by Dfuse
2nd Libray
3 Hold ENT + Power button to enter Download Mode to copy files, the problem starts exactly th ...
4 blue screen of death, I can not any more, not open USB
5 Back to deviation 3.0
6 Do all of the above
7 My radio works ... I do not understand!

This photo is just to certify that you guys in 3.0 works fine!
Deviation 3.0 USB mode works perfectly

when installing 4.0.1 are you using the dfu and the library file from the same zip file?

deviation-devo12-v4.0.1.dfu

which is installed using the dfuse 'firmware' tab and using the upgrade button

and

devo12-lib.dfu

which is installed using dfuse 'library' tab, also using the upgrade button

both of these files are inside the below zip file

Hello friend thanks for the reply, but always at the Libray Upgrade, do not upload, If I had done the Upload file which would have to send it again? tell me his name? thank you! I'm talking about the 4.0.1 zip deviation

A blank screen after installing Deviation in my experience is usually due to an improperly installed file system, i.e. the firmware isn't finding the file system where it expects it to be.

This usually happens when the file system is copied over exactly as downloaded, which includes two folder levels that aren't needed when installed on the transmitter i.e. the top level called 'filesystem' and the next level labeled as the devo12 (or devo8, devo10, etc., depending on which version your have).

Only copy the files inside the Devo12 folder to the transmitter, not the filesystem folder, or the devo12 folder itself.
