G928X Live Demo Unit without fingerprint sensor?

Hello,
I got a Galaxy S6 Edge+ Live demo Unit (G928X) and installed the latest firmware for G928F as I always do with the LDU devices. Unfortunately the fingerprint sensor doesn't work (I get an error message that there is a problem with that sensor and I should reboot) in my former S6 Edge LDU (G925X) the fingerprint sensor worked after installing a "normal" ROM.
Does anybody know whether the did not build in a fingerprint sensor in the G928X? Or is there a "trick" to get it working?
Thanx a lot!
best regards
I have the same problem on my g928x ldu ,after flashing g928f firmware the fingerprint sensor doesn't work , the cpu doesn't enter in deep sleep mode so it drain around 3% battery per hour in idle and the maximum cpu frequency is 1.3ghz for little cores and 1.8ghz for big cores. I tried a lot of roms and kernels but nothing changed.

You need Twrp or CWM Recovery to do factory data reset after flash normal firmware and everything ok
Hello, sorry to use this thread, but i want to ask people you owns this demo if anybody open the phone? I ask this because my g928f had an accident and completely broken LCD and back cover. So it is more cheaper if i buy a demo and replace the motherboard. My doubt is if USB porting charge of demo have connectors for antennas?

S8 Duos G950FD - Dual SIM + MicroSD Card Trick Blocked in Latest Update

Dears,
I just updated the firmware of my S8 OTA and the SIM+MicroSD trick is now blocked, it is not even possible to enter to Android until the card is removed.
This trick was blocked last year by Samsung on Android 9 on the S9, and now it is included in the lastest Android 9 S8's firmware update. There is a thread within the S9 forum about how to remove the restriction in a S9 but requires rooting the phone.
For the moment I will revert to the latest Android 8 version I had yesterday using Odin, but is there are any suggestions for the S8 without rooting, it will be appreciated.
Regards,
