Note 8 N950XU Live Demo Unit Security Error, need HELP !

Hi, i have a Note 8 N950XU with Snapdragon, it worked fine with the pre installed Demo ROM, but i installed the N950U Firmware and since then it shows me Security Error: Unauthorized Software has been flashed bla bla bla, as you can see on the attached picture. I even got the original N950XU Demo Firmware and flashed it, but still shows me the same error! Anyone knows how to fix this ? Odin passes through with no error, but the phone never boots up, only the security error. I just want my phone back to working order :crying:

OEM lock?

There was no option to turn it off or on in developer options, is there any solution for this ?

SM-N950XU is NOT a device to be sold to customers, but for retailers only!
Where did you get this device?
The solution is on the screen...

I wonder if the demo model has a locked bootloader?

Hello. I actually have the same model. I'm wondering how I could flash another firmware to replace it. How can I root and install a custom recovery to this device?
Also own a s8

Go to a Samsung Service Point and ask there; or are you afraid to lose your device because Demo-units aren't for sale to customers?

How are people even getting these? Are they stolen from retailer store fronts? These should not even be out in the wild. SMH.

I don't know what that is. It's not connected to any carrier. SM-N950XU

BlueFox's thread:

I believe you would have to use Prince's Odin to so which is also in that thread.
Looks like your just trying to flash another carrier's or other official firmware. Don't need unlocked bootloader or oem unlock for that. Don't know if your version has an unlocked bootloader but I am curious.

Not gonna work on N950XU, that's what the OP is about. These are retailer demo units and you can't just flash other models' firmwares onto it.

I believe they do, but they also have the security check which was tripped by the OP when he tried flashing 950U firmware. The question is whether there's a way to get around it, which I am not qualified to answer. But I am still wondering how these retailer demo units are ending up in private hands.

Right. Probably ex demo units that get sold off before too much screen burn occurs. I don't know to be honest.
I remember reading somewhere the radios don't work on them hence they needed a new main board to function fully. But that was just a random post I'd come across that I recalled.

I actually recall reading something similar. But I also remember being able to make a call with demo units, could be wi-fi calling though, so I dunno.

[P BETA] Last OTA update broke the phone

Hey,
I was running Android P Beta, and had an OTA update today.
As it's been said on the beta topic, it apparently put me back on Oreo (the pattern lock is different on P).
But now I can't unlock the phone with the pattern at boot. When I put it the right pattern, it gives me a black screen, and ask me to unlock again.
So nothing's coming up, no wifi, no backup etc.
Does anyone have an idea on how to solve this **** ?
Thanks guys.

I know I could do that, but I'd like to be able to get some data back first (like whatsapp messages).
Whichi is why I'm trying to find a workaround, but so far it's not really a success.

i think that OTA update on Android P is in real "Android 0 8.1 June Update", as mentioned here, if this true that's the reason why you have problems

If the workaround to bring back the oem unlock toggle isn't working, then you will have to wait the 7 days for it to appear. Then you can toggle it and try installing twrp again. You likely missed a step in the process last time which resulted in 'jail'.

Reboots don't affect the 7 day timer. Your uptime timer will reset, but the 7 day timer for OEM unlock is server-side.

I'm not sure but I think that installing the update could restart the 7-day wait period. If you want to root as fast as possible then it's probably safer to not install the update for now and just wait for the OEM Unlock toggle to appear. There is also a stick thread here with a workaround to skip the 7 day waiting period, but it didn't seem to work for everyone (although it did work for me the one time I tried it).

Any luck///need help too.
Any luck with getting the OEM to show?
I've tried them all waiting 7 to 2 weeks, factory reset change date at setting up insert sim card and no luck. I got my note 8 at soon as it came out so maybe it has something to do with it? I want to root it so bad it cant because of no OEM. Any new information would be great!

Damn, sorry I thought I listed it. I have a t mobile note 8 where the OEM wont show up and a unlocked note 9 N9600 where the OEM is grayed out to which I tried Odin flashing N9600 CPT/TCP version (not to sure right early this moment) and the flash passed but the phone was exactly the same without any changes and still the OEM was grayed out. I tried 3 different methods of changing dates on both phones with no luck. Any kind of new information or version ti they and get this OEM to work for me would be greatly appreciated.

Ok the T-Mobile model has a locked bootloader that can't be unlocked, so OEM unlock won't work.
The N9600's bootloader can be unlocked though. I have tried the date trick in the past on another Note 8 variant and it worked, but I have since read different things such as recent firmware updates stopping the trick, or needing to jump more than 30 days ahead instead of 7 to make it work. Not sure if all that's true or not, but if nothing works then I would probably back things up, flash original firmware through Odin with full wipe and wait 7 days to see if OEM unlock appears.

Yes I know the t mobile bootloader cant be unlocked but still can get be rooted and use some mods with the lost of 20% battery lose but one has to get OEM unlocked under developers options (that option never shows up for me) I've tried 7 to 14 day without reboot but not 30. I've give that a try on the note 8.
As for the note 9 N9600, I thought it came unlocked already but still just need the OEM unlock switched, which for me is grayed out and cant be switched. I'll use factory reset on both and try the 30 days trick instead of 7 and see if itll work.
Thanks for the info.

Yeah the samfail method for u.s. snapdragon models was patched by Samsung at one point, but it depends on which version bootloader you currently have installed if I recall correctly. Check through the samfail thread for more info there. I have an exynos, so can't say for sure about n9600 but that's what I would try at this point

I cant do anything without figuring out how to get OEM unlock to show up on my note and OEM unlock option greyed out removed from my note 9. The only step one found was the tricking the device on changing the date and that didnt work on the note 8 (going to try it for 30 plus days and see if thatll work) as for the note 9,,,,,,, I dont know why it's even grayed out.

Like I said you won't get it on the T-Mobile model (and iirc it's not needed for samfail, even if you are on the proper bootloader, etc.), but you can always check the 9600 and/or OEM unlock threads for more on that one if the stock flash/wipe and waiting period approach isn't preferred or doesn't work out.

It's quite simple.. You download the latest version of firmware for the device which is N950USQS6DSI3 after it's downloaded you need to unzip it one time and then boot the phone into download mode and connect it to the PC USB port and open Odin and put the files in their respective place and then flash.

Doesn't matter they're all the same just choose whichever and flash it the phone will choose the correct information on it's own!

Are there update limits? I usually get a new phone, root it, find a rom I like and stick with it a long time. I recently updated many apps and they are not working right. Only google maps will get the location from the GPS for example. Also trying to get it to work with my new car radio (kenwood) with wireless mirroring and android auto. Anyway, as much as I like root, I am thinking it may be time to just update. I am currently at N950USQS2BQK2. Yeah way back. Can I odin a current like N950UOYN7DSK3 or do I have to go in steps? Also how do I get an unlocked USA from sammobile? Just pick a USA that doesn't list a carrier? Any other gotcha's since 2017?
Thanks,
Bob

Question this may update is terrible

If it's the U1 3AUDD update you can't downgrade. The bootloader revision has been bumped to 3 and there is no going back to bl 2.

I'm pretty sure you can't downgrade because the bootloader is a different version than the previous version. The number that is shown 5 characters from the right on your Build Number identifies the bootloader version. The May update took me to bootloader version 3. Prior to the upgrade, I was on bootloader version 2. Forgive me if I'm wrong, but I don't believe you can downgrade once you've updated to a different bootloader.

Are you in the US?
I haven't tried to tether with this phone.
So, you're saying that if I tether, it will check with T-Mo or whatever my carrier is to see what I'm eligible for?
I guess that was 1 benefit about the Pixels. No checking, just tethering!

Very happy with May update

Download Activity Launcher from the play store -> go to the search on the top right -> type in "tether" -> it should search for "Mobile Hotspot and Tethering (there should be 3 that pop up) -> choose the 2nd one -> click on "WiFi Hotspot" -> click On.
I don't take credit for this as I found this on reddit. It worked for me and a few others. Good luck!
