NEED HELP with S8 Plus Retail Demo Model

Hello XDA Members
I tried to flash a stock rom into this s8 plus retail demo model# G955XU through ODIN 3.12.3 using stock firmware from sammobile. I get a PASS from ODIN but when the phone reboots and tries to install the files it goes upto 32% then restarts then this message comes up:
"Security Error: This phone has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair/return for this issue may have additional cost"
I tried 3 different firmware from BELL, Rogers & Telus G955W Canadian carriers but no result. Also when I unzip the firmware files from Sammobile I get 5 files BL. Ap. CP. CSC_OYA & Home_CSC_OYA but in odin there are only 4 slots. I tried both home and CSC file into the CSC slot but no results. Your help will be greatly appreciated

Why do you want demo mode? It's literally a resource hog and can only be removed with hard reset. If you want the demo videos that come preloaded, you can download them from the Samsung retail website

Thought the same thing, 1st post, joined today, asking to flash a demo phone. I'm sure theres ways of getting a demo phone legitimately, i just haven't heard of one this early in a phones lifecycle.

kind of wondering the same. hopefully that's not the case, but yeah, kind of comes off that way with the little information given.

Hello
Hello there
I am facing the same problem, flashed with Odin and got and error message: The phone has been flashed with unauthorized software & is Locked. Call your mobile operator for additional support.
Any way around this problem?
Do let me know guys

In Europe for the S6 and S7 the demo units do not have the same hardware as the retail products for cost efficiency. There is therefore no way to get them to work with a retail software version.
I have not had any feedback as to the S8 but chances are that it is the same.
Shops here often get them free of charge and some do sell them to make some extra money.

1. Sounds like a stolen phone?
2. Hardware may be, and likely is, different as another user pointed out.
3. Even if you got it to work you couldn't make phone calls or use mobile data as the IMEI will likely be blocked/blacklisted by all the telcos.

Hey there guy I got a S8 SM-G950X LDU . Anybody knows how to flash it with odin?

This just doesnt seem right.
It is likely a stolen phone or something else.
I am closing thread for now.

hello guys. i have leeco le pro 3 x720 and And today I've updated my phone. rome 23s to 26s. and i have problem i need account for active username and password.Because this phone does not have my country
pls help meeeeeee i neeed account . Someone can make up for me acount plsssssss

http://sso.le.com/user/emailreg?ver=3.0

I've been wanting to make an account too but there is no UK /GB option to put my phone number in and I can not proceed Is there a way?

My country is not in a list also, and I think I tried most of combinations I could think of what includes real number after wrong country code, country code after country code and then number, etc., etc. but nothing worked.
Tried to register via US site as well, but nothing.

LeEco ROMs only come with so many countries and languages. Sorry, but you'll have to flash a custom ROM that has support for your specific country or language. Don't bother with an LeEco account, because it isn't going to help you. 1) LeEco is bankrupt and 2) their servers are down.
If you're using an x722, you'll need to downgrade to the 01D (developer) ROM before attempting to flash a custom ROM or TWRP, or you'll brick your phone. I don't know if this is a necessity for all variants, but it is a necessity for the x722 variant on official 26s.

Create leeco account using baidu account you don t need phone number for that
Check in youtube there is video showing this method

Brain is melting.. Confused over which firmware I need!

Hello to all, apologies for my first thread being of the begging variety! In my defense I can promise that I have spent way tooo many hours spent searching for the answer I seek.
In brief due to my wife having a tropical moment and upon forgetting the screen lock password, followed by formatting/wiping plus the icing on the cake being she forgot the required synced Google account details..
I have succeeded in removing the frp lock but I think I've ballsed up along the way.
My problem is that I don't have a Scooby-Doo as to which (full/4 file) firmware I need. Every search leads me to multiple different regions, none of which are UK/GB (I am in UK using UK "three" network. Phone model number is,
SM-G531H/DS (grand prime duos)
Could anyone please help me out and tell me what firmware is needed.. Using odin 3.09 and Samsung Z3X tool Pro. All drivers installed. Phone won't go into safe mode, can access download mode and the dos type menu too.
Very much appreciate any help.

Samsung Galaxy S8 G950U - FRP locked

Hi. I purchased a preowned Samsung Galaxy S8 and I am not able to get it running. The phone has factory reset protection and it asks me for owners google account. The seller does not want to provide me with that info because of privacy issues. He said that he deactivated that option through google account, but it did not help. I've tried all the methods that I found on YouTube and through google but none of them seem to work. - the "two finger" method turns on voice assistance but does not enter Tapatalk menu
- the setting method does not work wither because I do not have the "help & feedback" menu
- others like installing SideSync on PC and connecting phone through usb, nor any other that I found online did work
I also tried to call Samsung support but they are asking $70 for unlocking and I would need a proof of purchase with IMEI address, but the seller did not include IMEI, anyways its to expensive.
I went to some phone repair stores but they were asking from proof of purchase from Samsung authorized store, they did not accept eBay...
It's an unlocked T-Mobile version Samsung Galaxy S8 SM-G950U running android 8.0.0.
This is whats the Android Recovery menu showing - 8.0.0/R16NW/G950USQU5CRK1
Is there any new/working way to unlock this brick?

When i bought mine and factory reset it this happend to me also. It is fixable tough I followed these steps but from another video that i can't find atm , hope it works for you

have the previous owner call google. they can track the IMEI and verify the previous owners credentials allowing them to release the FRP lock and making you the full complete owner now

i know this post has already been quoted and therefore what was posted is still there, but have you been able to get past this FRP issue as of yet?

discussing FRP unlock methods outside of googles prescribed methods are against XDA rules. Please refrain from discussing things of that nature.

I am faced with a Dilemma...

I have a Galaxy tab S6 lite that is locked by a pattern and I don't have its gmail since it was used by another PhD student at our department. Factory reset did not work since I still need gmail. I also tried flashing it by odin but I didn't find a firmware with CP file, and hence even after flashing it I still could not log in. I could not install lineage because it says "only official binaries are allowed to be flashed(recovery)". Perhaps to install lineage I need to activate OEM, but how could I while it locked. Do you have any suggestions on things that I could try, I am getting desperate with this! Thanks!

Yeah. Ask your department head how to unlock it.

@Fethi_02 let me remind you of the Forum Rules:
9. Don't get us into trouble.
Don't post copyrighted materials or do other things which will obviously lead to legal trouble. If you wouldn't do it on your own homepage, you probably shouldn't do it here either. This does not mean that we agree with everything that the software piracy lobby try to impose on us. It simply means that you cannot break any laws here, since we'll end up dealing with the legal hassle caused by you. Please use common sense: respect the forum, its users and those that write great code.

Does this device belong to you? Are you rightfully in possession of it? Do you have the right to use it?
If the answer to any one of these questions is "NO", you may not use XDA to seek any more assistance on this matter, and we recommend you return the device to its rightful owner.
However....If you are in legitimate possession of this device, I suggest you contact the person you bought the phone from. Most Android phones these days have "Factory Reset Protection" which is an anti-theft measure intended to prevent stolen devices from being wiped and re-used.
Failing that, your only option is to seek an FRP unlock, or return the device and request a refund. Either way, all activities conducted here on XDA must be legal and legitimate.

Come on man.
