Devo6 problem to go back to walkera devention

After successfull test deviation on my devo6 i would go back to devention firmware.
After upgrade the firmware and upload the library i got a wrong displayed background.
The tx is functional, objects (boxes, icons and so on) displyed over the background but not cleared before actualized.
Any ideas?

Verify ends with 'Verify successful !'
The background shows like one interprets a textfile as bitmap (some stripes with pixels in different colors)
With 'not cleared' i mean that for example the timer value is not deleted and the next value is drawn over the old value,
same as you write characters with a pen on the same place again.
Or if i choose the system menue then the icons are displayed over the last screen content and on exit this menue the icons are allways shown.

Sorry for my bad english.

Re-uploaded the firmware serveral times (different versions)
My actual version is FWD v0.5A and Lib v0.3
It is a 100mW devo6 with installed telemetry upgrade modul
Tried also regular FW (not S-type) without success

I will now try the STMicro DfuSe tool to download the lib.

Edit:
Uploading the Lib v0.3 with STMicro DfuSe has not solved the problem.

I have now upgraded to FW v0.6A and uploaded your Lib and Config.
Verify was successful for both.
Problem not solved.

Might get you nowhere but did you try uploading the library first then the firmware?

No, I allways uploaded ther firmware first.

I will try later uploading the lib first.

Upload or upgrade?
It is very important, because in that tool upload means saving from the tx to the pc...

My meaning was write the library first on the Tx, then the firmware (I suppose the way it's labeled in Dfuse would be upgrade indeed).

Removing the battery I have tried.
Deviation works fine.
With Walkera Devention I have flown my heli, its works normal except the screen.

I have used several Walkera firmware versions and the coresponding libs without succces,so I think the images are not corrupted (in the file) and the verify was also ok.

How can I download the firmware and config from the tx?

With the Walkera DfuSe tool I am shure I upgraded the firmware and uploaded the lib

With the STMicro DfuSe i am not really shure.

I try it again.

Upgraded the config and lib again the screen shows ok.

I think I have UPLOADED before.

Now I try the walkera v0.3 lib.

Thanks so much for your help.

Yes, my devo is full funtional now.

I will write down the steps wich solve the problem and make screenshots too.

But give me a little bit time for that.

Thank you very much.

my screen looked the same when i first tried to load it and i had to reload it but i loaded the library first..then the FW..if i remember correctly..

Since my Devo6 is now completely ok again with your help
I describe here how the problem arose and how to solve or avoid it.

My approach was the following:

Installation DEVIATION:
- TX off, TX on with EXT pressed
- Upgrade FW (used my build from snapshot d44742f64ed5) with Walkera devention DfuSe USB Upgrade Tool
- leave DFU Mode
- --> Screen shows Message:Filesystem could not be mounted. Create the FS via ...
- Message ignored, TX off, TX on with EXT pressed simultaneously
- Upgrade Lib (deviation-lib-devo8-1.00.dfu) with Walkera devention DfuSe USB Upgrade Tool
- leave DFU Mode
- --> Screen was complete black now
- TX off, TX on with ENT pressed simultaneously (to reach USB mode)
- format USB-drive
- copy filesystem (from my build) to USB-drive
- ENT pressed
- DEVIATION is installed and works properly.

Going back to Walkera Devention:
- TX off, TX on with EXT pressed simultaneously
- Upgrade FW (in my case DEVO-6 FWDT v0.5A.dfu) with Walkera devention DfuSe USB Upgrade Tool
- leave DFU Mode
- --> Screen was scrambled now
- TX off, TX on with EXT pressed simultaneously
- Now, I made the fatal mistake!
- I UPLOADed the Lib
- (selected the file in the file explorer wich corresponded with the ---firmware and ignored the message that this file already exists.
- So I overwrote the original Lib with something from the DEVIATION installation.)
- leave DFU Mode
- --> Screen was scrambled as before ( shure, the Lib was not upgraded)

- I think I repeated this step with multiple lib versions and ruined it all
- Later UPGRADE with VERIFY (with the ruined libs) always reported everything was ok (shure, compared the ruined file with upgrade of the ruined one )

- Then I posted my problem here and got help quickly.

- Having UPGRADED with a correct lib (provided by PhracturedBlue) and everything worked as expected.
- I used to the STMicro DfuSe tool which PB suggested
- Today I have everything reproduced several times and was able to produce full function (original libs used).
- I have the STMicro DfuSe tool no longer required for that.


Resume:
1. Deviation lib install does not work for me by DfuSe tool
So create filesystem viar USB

2. Be shure to have choosen UPGRADE not Upload to install FW, Lib, Config
(Use Upload only to save Lib or Config to your PC and choose a meaningful filename for the uploaded file)

3. Upgrade only with correct files
(Hint: size of uploaded Lib files is 4.033KB, original walkera Lib files are smaller)

Thank you all who helped me here.
