My Cybook Opus is working again with 2.1 firmware. You only need to download one more file and upload it on the SD card. Cannot tell you which file and where to download it cause this info is for private use only.
And thanks for you answer then i just wait to see answer from Bookeen if any.
Thank you all for trying to help me
