How do I remove Samsungs Live Demo Unit Software?

How do I remove Samsungs Live Demo Unit Software?

Hello all! I have recently bought a lot of samsung smartphones on eBay. They are all Live demo Units. I am aware that there is no baseband in this phone and no IMEI assigned to them so it will never be able to connect to a cellular network but im getting really annoyed with the live demo software and would like to know how to remove it. I would flash with Odin but im on a MacBook Pro so thats not an option.

Check post #10.

You may be out of luck on the demo unit models as the firmwares probably have hard coded live demo app installation even after factory resetting / wiping the phone."

"you know what all your answers are wrong. also checked on other forums the 5444 and m729 is only use to access retail mode app in order to set ldus settings and also to register the store where the ldu is being setup.. i have a friend from samsung and good thing he’s from hhp fieldforce he taught me how to disable or freeze the retail mode inorder for user to use the ldus but take note you can only use it like tab you can download games and store files like ordinary tab or ipad without sim. so here it is

you need the 5444 and m729 to open retail mode app

on the retail mode app on the upper part you will see the “3 dots” like settings drop down you’ll see 3 items there. now go backhere is the trick. on the lower part right at the middle of your screen just tap your screen there 9 times. dont worry at your 6 tap youll see a notif to click 3 more 2 more 1 more ..then voala!! go back to the 3 dots on the upper right part open it and youll see now 4 items the last item will be deactivate retail mode, tap deactivate then it will turn to activate meaning its already deactivated

now to fully use the phone you’ll see also under option the lock/unlock auto factory reset. you need to turn it off so that your phone will not factory reset every day during 9am gmt lols..

—-owkey hope this one will help you. been using s8+ ldu for a year now. this one applies to s8 to note 9. and to s7 and lower i hope you will find the retail mode global neutralizer i guess the file is being leaked ol where in you download the apk file install it and it will corrupt the retail mode app and automatically freeze the retail system that s been hard coded into the ldus. i dont have the file myself but my friend does since he is using s6+ ldu before.."

This may not help but here are the passwords for retail mode. passwords - 5444 and M729Q16K8546.

You can remove Retail option in this phone but can't use sim, for this sim issue you have to use extra device ...which is called Gmate Smart

"You can still flash.

Call on Heimdall, and tell him to activate the bridge.

Use Heimdall instead of Odin.

Here is a tutorial.



Here is a iFixit thread on disabling Retail Mode.

How to remove retail mode?

I'm not sure if its in this thread, but I've read somewhere even though you can remove the demo software, the phones are neutered so they can't make calls."

"^ YES! Kinda jerkish to give us this trick (and of course this is the only place on the web I’ve found that this is posted) like finding the hidden deactivate button … and then not giving us the pw. RAWWWWWRRRRRRR!

Regardless, if you disable factory reset using the aforementioned passwords, delete the hidden files, go back to main menu and disable content protection then go to settings/apps/special access (under the menu at top right)/ device administrators you can can uncheck the retail mode app and deactivate that way.

I also denied it permission under apps that can change system settings just for good measure.

Get Package Disabler Pro (Samsung) in play store and disable both retail mode apps (samsung and retailmode), Discover S8+ and anything knox related (also just for good measure).


I dunno, but after 24 hours or so it seems to be fairly retail mode free, and I didnt touch Odin. With the retail mode service gone, i cqn charge past 70%, power saving mode and airplane mode work fine, obviously cell radio/SIM reader isnt even in the phone so i cant make calls, and factory reset is still missing, but why would I wanna go thru all that again anyways? I just got a $50 S8+ with some minimal tweaks. I’d say thats pretty rad."
