Why do you have a demo phone and want to use it on a carrier. Sounds stolen.

At this point I think this question does indeed belong to the developers section. It would be pretty cool to be able to convert Demo Units to normal phones. I have a lot of friends who own mobile phone shops and would like to make this conversion. Besides it is a shame to have a half-working S4 and not be able to make it work!

Hope that developers can solve this in the future and I would be happy to donate as there is a chance to get my hands on a demo unit, too.

No one in this forum will be able to help with what you need. If you are in Romania, you will need to re-post this in the Q&A section in the international S4 forum.

Go into the Samsung retail mode app. The passcode is 5444. Go to demo mode timing or something like that and set it to start at like 4:00am and finish at 4:01am. Thats what I did. Works a treat :)

please open tis phone and make few pictures of it. I mean mainboard. Then we will know if is possibility to fix it or not.
Because if is radio(modem) on this unit is possible. if not it isn't.

But second think which we need is unlocked bootloader. But first please share a photo.

But if we use that trick (for running live demo video for one minute only) the things we store on the phone will still be deleted? Cheers

Yes, it will. It will even go as far as deleting you r SD card if you insert it.
The wipe in recovery mode won't do the trick either if you have the LDU. The retail mode DCT and retaimedia.zip are integrated in the software and when it reinstalls the apps it will reinstall the RM. Flashing a I9505 firmware on I9505X doesn't work either, it messes up the wifi radio and other things.
