Hello guys i need help regarding my htc one m7.

I tried to go back to stock rom with a HTC ONE m7 fw 1.29.401.12 and did not know that ruu version have to match exactly the fw version since i have s-on.
I locked the bootloader and therefore all data were deleted on my phone so all my backups and cyanogenmod installation files.
My bootloader still works this goes also for twrp.
I researched for hours and found a solution with adb sideload but i am just not able to properly transfer the file.

I have htc sync installed and also sdk tools adb etc.
When i go into recovery and open cmd command in platform tools and type "adb devices " i get this : List of devices attached
name of device device
so everything is good till now.
Now i go to twrp and put the one into adb sideload then i get the following result when i type adb devices :
adb server is out of date. killing...
* daemon started successfully *
List of devices attached
name of the device sideload

So this is my problem guys i need to transfer the file but i dont know what is causing the problem would be awesome if you can help somehow.

Have a nice weekend all!
