Nah, I tried that as well and that didn't work. It Odin flashed the other partition and then it just hang there.

That would be related to the ROM in question then. Hidden is basically all junk/bloatware data. As long as the partition itself isn't flat out corrupted the system doesn't care about what's there other than to install APKs put inside on first boot.

Hi there, I also have a DEMO Unit here SM-G920x, after a lot of back and forth, and a short period of "bricked" I managed to install TWRP via Odin, and then flashed this rom http://forum.xda-developers.com/gal...xtrestolite-deodexed-mod-edition-1-0-t3094423 via TWRP , it seems to be working fine until now, all demo stuff is gone. It was even asking for the Sim pin, which I didn't have. I will report back when I tested a little more.

Hello, I have a G920x LMY47X.G920XXXU1COH3_LLK. It caharges only at 70%. Any ideea how to fix this?
Thank you!

I have demo unit of htc one M8. I rooted and installed custom rom. Its works like a normal phone now. Hope this can be applied on Samsung as well. Let me know if u already tried that. Someone is selling Samsung S7 live demo unit in my area. Im thinking to get it if it works like that.

If you download this.
https://download.chainfire.eu/733/CF-Root/CF-Auto-Root/CF-Auto-Root-zeroflte-zerofltexx-smg920f.zip

Extract it. There is a copy of Odin in there and the file you need to flash with Odin.
Run Odin. The window will open....

Shutdown the demo unit. Then hold down down+home+power until the logo "demo unit" etc comes on.

It will go into the warning page. Press up to put it in download mode.
Connect your computer to the unit with the USB.

But my guess is of yours is the same as mine Odin won't recognise the unit.
Does Odin show a blue/green bar?
Does text come up in the message window?

If it does find the zip file that came along with Odin inside the original file I linked. Put it in the box that says PDA (or its PA now I think from memory they relabelled it.)
Press start.


I bet it doesn't work and nothing will change.
hello i have done this...now i can see 3 apps: "superuser ", "retail mode", and " samsung retail mode".

If I replace the mainboard with a board from a original disassembled s6, will it make it gsm working phone ? I don't know if the ldu has gsm antennas though...

How do I remove the screen burn in... It's still bothering me after flashing the firmware which has everything hidden. I had an option to remove it within the retail mode app but now I don't.

Hello,

I got a Samsung galaxy s6 SM-G920X live demo unit. I was able to flash twrp 2.8.7.1 and then root it. I tested that root works fine by installing root checker application and also by uninstalling some system apps (like retail mode app) using es explorer's root explorer option.

I would like to know if some one here flashed any working custom ROM on this model successfully.
If so could you please post the details on it?

Thanks,
Simon Mandy

Hello,

I spend couple of days. And so far i have been able to flash twrp 3.1.1-0-zeroflte and root the device with stock android 5.1.1

    I would love to but I went looking for what you'd used. found the factory reset code. wiped.

    signed in including the fingerprint thing. Samsung installed a software update even though I didn't sign in for samsung. wouldn't let me cancel it. It auto rebooted. Now I can't unlock the damn thing. It knows it should check for thumb prints. won't do it. There is a backup password thing but it won't let me use it.... I'm locked out.

    It might be deliberate.

    So does anyone think it would be possible to connect/install the necessary hardware from a non-demo device and get these live demo units to work as a full-fledged device?
    every LDU generation the same questions ... :D
    I didn't open a S6 demo unit but other samsung demo devices. There are ICs missing on the mainboard. I doubt you could buy this special hardware somewhere. Then, these chips have to be soldered ... (from the backside), the contacts are missing on the board ...
    So my answer is no, not without changing the mainboard. You probably could use the board of a crashed phone and put it in the demo device (when they did not change anything else) for former LDUs this was possible.
