SM-G930X Can't Enter Download Mode - Samsung Galaxy S7 Questions and Answers

I recently bought a SM-G930X Samsung Galaxy S7 Live Demo Unit to use with my Samsung Gear VR. I used a Youtube tutorial titled Samsung Galaxy S7 G930X Live Demo Unit removing retail mode.
Unfortunately, I think I made a boneheaded mistake. In the video he uses Odin to install twrp-3.0.2-2-herolte.img.tar, but I installed twrp-3.0.2-3-herolte.img.tar. So, total n00b question here, I'm assuming I made a mistake, right? I can tell because now no matter what I do I can't seem to get back into recovery/download mode to be able to install the correct version. Can anyone point me in the right direction to fix this? The phone will still boot - I just can't get recovery mode to launch before it turns back on.

Galaxy Ace S5830B does not start, neither download mode appears.

You have likely heard the saying "From good intentions hell is full." So today was a shame to me.
A friend of my wife's father wanted her to upgrade android 2.3.4 for a custom, to take Tim's Android, etc.. then she called me to do this.
So I did not pay much attention, and installed a ROM S5830i instead of an S5830B.
Result: no boot screen it appears.
I've tried everything. Start recovery mode, download, push all the buttons, but it does not even appear on the backlight.
Heard of a device, the USB JIG. He sort of "force" to open the galaxy in download mode, but I did not want to spend money.
Anyone know what I do?
PS: My phone is with her, that is. I'm no cell phone.
Thanks in advance.
If I have the same problem with galaxy pocket can any body help pls?

[Q] Got Galaxy S6 live demo unit. Model no. SM-G920X. Need help

Anyone else have one? I want to completely remove the demo software and use it as a tablet. Now please note I am looking for an answer that puts the instructions in steps like you're talking to a baby. Assume I have no experience in any of this. I also only want answers from people who have been successful at doing this and own the device.
Also I want to know: are the specs of a demo unit exactly the same as the normal retail version?
Build number if needed is: LRX22G.G920XXXU1AOD7_LLK
Bought in the UK.
So far I've turned the demo stuff off as far as I can. I entered the password 5444 and whatnot to disable it.
Also:
Fast charge doesn't seem to work. Charges quite slowly.
I get this error when I try to install certain apps: unknown error -501.

If it's a live demo unit it's probably crippled in most ways. Wifi, Fast Charging, Cell Radio, things like that are all probably affected by this. Live demo units are primarly there to show a "finished" product. It's there to show of how pretty the exterior of the phone and the screen. Maybe the camera. But it's probably a pre-release version. You're going to have a bad time trying to make it work for your needs. Best of luck.
Thanks but I'm looking for help from people who have the demo unit. I have a galaxy s4 demo unit as well and it's fine, had no problems
OT why are u fun of getting demo units, aren't these supposedly be for demo purposes only?
Why not get the retail and get rid of issues. If u bought it then you should be getting a retail/production phone than demo UNLESS you paid it for less ... Lol

Yes I bought it for 1/3 the price of the normal phone, and I don't need the phone features. I am asking how I can completely remove the demo software. I prefer someone who already owns it and has tried it, to answer.
I've bought the same. mine is clearly removed from display because it's had a bash. So I think it shouldn't be a problem.
I've been trying for the last couple of hours. Can you get yours to be recognised by odin? I couldn't at all.
I turned developer mode on to use adb sideload but it has been no use. the device says everything has the wrong footer and validation denied.
what else do you have besides 5444? That's the first I've heard of that.
Hey Quarzar, the other password needed to turn disable factory reset off is M729Q16K8546, after you've entered 5444 to enter the Samsung Retial software. But even after factory reset I'm stuck with the demo software. I haven't tried Odin, will have a look. I don't want to flash something and risk bricking it.
Quatzar can you try something? Can you try installing 3DMark and run the ice storm unlimited benchmark on your demo unit and tell me what you get?
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.
Darn that is annoying, so glad I never tried the fingerprint thing now. It auto installed two updates for me as well without asking me
Easy easy dude
Hi, look its very simple!
You have to ROOT your device, then istall Titanium Backup on it and the open up the Programm and through its options you can UNINSTALL anything you want, even the retail software! Thats it:good:

Ok back awake now.
If anybody gets locked out, just use android device manager in a browser and wipe the device.
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.

Please can you show me how to root it in baby steps? The most important thing is, have you done it yourself on a galaxy s6 demo unit? I don't want to follow a procedure for the normal s6 and then end up bricking my device.

Hi Quatzar, yes Odin recognises it I think. It says 'added!!' and the blue bar under ID:COM. When I plugged the S6 in at first it did have to download 'Serial Gadget' update and Samsung something. But I don't want to flash anything until someone else has already tried it and succeeded, in case it ends up going wrong.

Galaxy S7 G930X LDU Retail mode removal

Hello,
I bought one of these to play around with it but this one seems to kinda go bat**** crazy. Android runs fine but It wont play any demo videos and it wont reset itself. Instead it constantly launches the samsung screen repair tool and flashes all kinds of colors and shapes. I went into the retail mode app and then the store settings and it asks for a password which I put in 5444 but it says the password is invalid. I see some people have had success removing the retail mode app and then flashing a stock rom. My question is does anyone know the passwords to the retail demo mode app?

Gear s3 Stuck at odin mode

Hello, as of many have faced the same issue by now, i searched alot and couldnt find a fix to my problem,
i have bought a samsung gear s3 frontier some time ago, i have ordered it from ebay "UK" i think and it was shipped to me in sweden, i discovered that my watch doesnt have samsung pay so i searched a little and there was few suggestions which none worked, so i left the watch as it is hoping it will be added next update or so.
yesterday i saw a video talking about installing a combination firmware using odin software and then pull some files and edit them using note book, i searched for combination firmware for my R760 watch and there was kernel 1 and 2 i didnt know which one to use to i downloaded 1 and used it on the watch , odin said it was successful but i got an error on the watch saying something about kernel 2 security and ofc error booting, i tried to search for the stock firmware to return the watch to work but the boot option/ wireless download gets stuck on the flower logo and stays there "didnt reach the stage where i need to click twice to enter AP mode, after many reboots and trying i got the watch to enter AP mode but the background was blue not black as it use to be, i ignored that and added another stock firmware which said fail on odin at 45% and it said old software resoted because it was failed,
Now im stuck at odin mode, every time i try to enter wireless download mode the watch just stays on the flower logo and thats it nothing, i tried the 2 sec hold power 1 sec release thingy and it didnt work no matter how many times i try,
the worst is the watch is not charging now and every time i switch it on it show booting and switch off again b4 i can do anything, and when i put it on the charging station, the station give me a red blinking light which means its not charging,
Watch : Gear s3 frontier SM-R760
on the download mode i remember it say software : official and locking is disabled
i would appropriate if i can restore the watch as it was b4 even without and samsung pay, i dont want to throw a 300£ watch for a software issue, please help me .
