can someone please help me - upgrade of my Max Carta to 4.4 does not work

i use the files and descriptions for Max Carta from here

http://ereader-store.de/en/content/8-downloads

my device arrived today with firmware 1.8.2

I used MFG tool as described. It runs through different actions and then the buttons turn green and it reports success.

However, if I then restart my Max Carta and check the Android version, it is still 4.0.4 and not 4.4.

Also, if I do NOT use MFG tool and copy update.zip to SD card root folder and do the normal "OTA update" via settings, then everything seems to run through very well. It shows the following text output after reboot

"
finding update package
verifying update package
Installing update
checking update package matching
done package matching
wirting logo
writing boot image
extracting system image
writing system partition
"

Then the system restarts and it is still on 4.0.4 !!!
No error messages...

What is missing in my process? do i need to replace the firmware? If yes, please provide links from where I can get missing resources.

I need 4.4 to run Mendeley. I want to use the device for sheet music PDF and without document management I will not be able to quickly access a piece out of my over 3000 sheet music PDF. Perhaps there is another solution instead of Mendeley - then I appreciate your help. I tried MobileSheetsPro but hand written annotations do not work in its PDF viewer - therefore, I want to use Mendeley that can open PDF files in the Boox Max Carta reader app, which seems to be optimized for pen use.

Thanks a lot,
Mario
