i have had my device rooted since the week i got it in october successfully, no issues. when i got the phone it was on the oi6 firmware, rooted it and put MOAR rom on it, no issues. then on the 23rd the day before i was going to go out of town i changed my primary google account password on my device, and for some reason i couldnt tell you why other than it didnt seem that it would be of any significance that OEM UNLOCK option was enabled so i turned it off not thinking anything of it, and right after i reboot the phone i found myself in a bootloop. only going to samsung galaxy note 5 powered by android with little red writing at top that says custom binary blocked by FRP lock. so i did some research and it became obvious what my issue was that the oem unlock should never had been touched. from what i figure, but that didnt validate why i was never given the chance to actually verify my account being that the device hasnt booted back into the os or any screen other than the splash screen i mentioned and download mode. thats the only two things i can access my download screen reads this

Seems this guy got his working

Try use Samsung KIES (or Samsung Smart Switch) on Windows PC to flash/restore your firmware. I've never had to this way though.
And BTW. This is not a "hard brick", so your thread title is misleading. It's "soft"...

They all come on the sticker that seals the two halves of the box. This is standard from Samsung.

mate, its really nothing to worry about, it isnt hard bricked,
i had the exam same issue, that oem lock can be a real pain in the arse,
all you need to do is download the firmware, and i mean not just the same android version, but the same, as in oc1 ok1, what ever version you were rocking,
in my case it was the latest firmware available on sammobile,
and flash it via odin,
after that you must wipe cache, data, and factory reset to be a able to use your phone,
once booted,
you can login with you google account, enable oem unlock from dev mode, and install custom recovery and do what you do from there.
cheers

ALL EARS

So long as you are using genuine Samsung firmware or smart switch you do not need OEM unlocked.
If Odin is not recognizing your phone something has gone wrong with either your drivers or your phone is in a bad state.
Power down your phone, if you have to because it is restarting, catch it so you get back into download mode.
Then follow these steps exactly as they are laid out.
Open Smart Switch, click MORE, click Emergency software recovery and initialization, click device initialization, type in your model number using caps and dashes such as SM-N9200 or whatever your device is, then input your serial number again using caps for all the letters in your SN, finally connect your phone to your PC and continue with the prompts from Smart Switch.
The problem is since you have a carrier version, smart switch may not work. There was a guy who said it would not work for an AT&T phone.
Good luck.
Edit: I checked in smart switch using the sprint model number and it took it so you should be good to go.

yes i can get it in download mode ive installed the drivers from samsung website for the note 5, and installed them. is there other drivers i should install fgor it to recognize it? i also am successful in getting smart switch to recognize the SM-N920P for my phone model but i am unclear on how to obtain the serial number that smart switch wants. ive tried the dec hex the imei esn hex and the spc none of which it accepts. i have the box and it doesnt say serial number anywhere so im lost when i get to that point

That is a problem then because you need that number. It should be labeled SN and should be a mix of letters and numbers. Perhaps sprint keeps those records on file.
Good luck.

Help with bricked (hopefully soft) Note 5

Guys,
I bought an immaculate second hand Note 5 for 160 euro/180 dollars/140 pounds including shipping. It comes with the charger and an official Samsung case. It doesn't come with the box or anything else. I won't have it until tomorrow but I'm just trying to get a head start at hopefully fixing it.
Now here's the problem. The guy I bought it from got it from his work place. It was on the Vodafone network but he got it unlocked. He also rooted it. When he went to sell it a couple months back he factory reset it and now it doesn't go past the "Samsung Galaxy Note 5" splash screen. He's had it collecting dust for 3 months now.
Does this sound like it'll be as easy as an ODIN flash? As far as I know if it gets stuck on bootloops or stuck at the splash screen it's soft bricked and not hard bricked.
I've attached pictures if they help at all but I doubt it. Apparently it's a lot cleaner than the pictures and doesn't have a scratch on it. He also guarantees it's not water damaged!
Any help appreciated!

You can easy reflash the original firmware with Odin. It's nothing major.

Wow! You really think that's all? Because it doesn't come with the box I won't have access to the IMEI or serial numbers. Do you think it'll be a problem? I also have no idea what model number it is but ill ask where he got it (he lives in Ireland but I think he works in the UK as we never got the Note 5 here) maybe that'll help narrow it down.

If i were in your situation i would install custom recovery thru odin then flash one of the many universal note5 roms. Just how i would approach that situation.

You are in good shape no matter how you approach this because your device is ALIVE. You would need to be worried if nothing showed up on screen (DEAD). That my friend would be hard bricked.

You can return everything to stock except knox. Once knox is tripped its permanent.? And once you boot up any rom, settings will identify imei, model #, etc...

With knox tripped you will lose just the warranty which doesn't matter anyway. Samsung pay is working if you keep stock rom without root. Try to see if you can go in recovery mode with vol up home and power and do a factory reset. Sometimes is resolving the boot problem.

oh cool Samsung pay will work! Awesome sauce!!!

Phone arrived this morning! Here's where I'm at:
The phone model is the n920s, apparently some sort of korean telecomm model.
I was successfully able to boot into recovery mode via volume up, home and power button. I tried wipeing everythiong and rebooting but it doesn't pass the Galaxy Note 5 splash screen. I'm now downloading it's stock firmware and going to try flashing it via odin.

So it seems I haven't completed lucked out after all!
My findings are that it appears to be a bad/blacklisted imei. I know there is paid options to fix this but how likely are they to work?
I also found that when I boot to recovery mode it gives me theses lines in the log;
dm-verity verification failed
need to check drk first
What is this?
Even after flashing the correct n920s package from sammobile via odin I have these lines.
Any help appreciated!

Don't bother with dm-verity verification. You can google and you can see. For IMEI go to www.imeigurus.com. They are very good and they can fix your problem for 35$ include sim unlocking for that amount.

I had a look at that website and I see they don't support my phone which is n920s version. In regards to forgetting about the DRK, I'm pretty sure that's why I can't boot my phone.
Just to clarify for all I seem to have three main problems now;
1 - IMEI is bad/blacklisted (Repairable).
2 - dm-verity verification need to check drk first (Not sure how to fix).
3 - FRP Lock is enabled/on stopping me from installing twrp etc (not sure how to fix).
Phone cannot boot up to enable USB Debug or anything.
Stuck only with recovery mode and ODIN mode.

Just to keep everything in one place for anyone else who has this problem, here is a private message I just sent to 123Unlock over at sammobile.com forums. He is from SRS(Simlock Remote Server) - www.unlocksamsungonline.nl
Hi there,
I've been reading through a lot of websites for the last 7 hours trying to fix a phone that I bought. I was caught in a scam and sold a Samsung Galaxy Note 5 N920S which has a bad/blacklisted IMEI, the FRP lock is enabled/on and the DRK needs to be repaired. The guy who sold it to me said he got it from his work place. He also said he got it unlocked (I don't know what network it was on) and rooted it. Then when he went to sell it he factory reset it and now it's stuck/broken the way it is.
After all my reading it seems like you/your company are the only ones capable of fixing my phone. Could you please help me. I'm obviously willing to pay for the job.
My phone does not boot but I can enter ODIN and recovery modes. For more information here is a thread I started over at XDA - Developers:
http://forum.xda-developers.com/note5/help/help-bricked-hopefully-soft-note-5-t3445232
To contact me directly here is my email - [email protected]
Look forward to hearing from you,
Chris.

Did you flash the stock firmware with Odin? Did you put the firmware in AP section in odin and it was successfully flashed? Sometimes after that it keep staying in boot screen for long time. Just turn it off presing the power key for 10 seconds and turn on again.

black screen asking for password to start device

Hey, all; Apologies, if this has been posted before, but I cannot seem to find this partilular issue. I had purchased my new T813, off a retailer on ebay, they indicated it was a store return, and had the google frp lock. I managed to easily bypass the frp in a Tab E, so I figured (quite incorrectly) that this would also be a no brainer... not so!
I have tried flashing several firmwares, (got one from Russia that seemed to work okay, but still had google frp. I put the earliest firmware I could find on it; "T813XXU1APD7_T813XAR1APD8_HOME.tar.md5" It failed, and I was stuck on download mode, and would only reset, using the Vol down/home/pwr buttons, only to reboot to a green screen, stating; "firmware update failed" (on the tablet, and the red failure in Odin). I could not get the flash to work, 4 times, and was worried about the tablet running out of battery, so I flashed (not knowing what the hell I was doing (how many readily admit that?) I flashed a 20mb file called; "BL_T813XXU2APK6_CL9829844_QB11715585_REV00_user_low_ship_MULTI_CERT.tar.md5" and the tablet was able to boot, past the Samsung flashscreen, but loaded up to a black screen stating; "enter password... to power on, or something like that" Does anyone know what the password is? I can't remember where I got this, there's so much scattered around the web, I was just reaching for anything... any help would be greatly appreciated.

Sounds like a stolen Tab, I'd say. ?

That's what I'd say also. Return to seller.

In order to bypass FRP, you have to downgrade the firmware to the lowest possible build as it doesn't have any patch to fix security holes.
Like mine, SM-P580, I had to flash Hong Kong firmware to bypass FRP as it's older build than US version. As long as you can downgrade firmware, bypass FRP is easy. I have done it within 3 minutes.
Power + Volume Down will force your tablet to restart. When you can get to Download Mode, try to flash a new an older firmware again, regardless region . If you can downgrade firmware, your chance is 100%. A build that forces you to have internet connection in order to continue until it get Google account verification is a build that need to downgrade. Older build allows to continue setup after Software Update check failure due to disconnected internet. The latest builds will lock attempt to downgrade so don't flash any new builds . I experiment with the latest build of Android 6 and Android 7, they do the same thing: check software revision and lock downgrade if a lower one is detected. I can downgrade Android 7 to Android 6 as long as that build has security patches which lock FRP bypass.
This users did it by downgrade from T813XXU2APK6 to T813XXU1APF4

Not necessary to be stolen. I bought mine without password or PIN, but forgot to remove the owner's Google account when flashing new firmware.
It activated FRP but I was able to bypass it to use the tablet.

First thing to do when buying second hand: factory data reset.
Everything else is stolen goods.

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 ?

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.

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?

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

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.

I was going by this thread? Maybe there is two versions, demo and live demo ? I don't know to be honest.

I bought it off of the let's-go app. I have no idea

SM-N960XU - Retail Demo Model

Thread Closed: even if it is completely innocent, discussion about how to bypass a locked device, stolen or not, is prohibited on Xda for obvious reasons.
Hey there, First time Posting but Long time Lurker.
I was wondering if theirs a site for a firmware for this device. A buddy of mine bought one off eBay and well my buddy forgot to unlock the OEM and Enable Debug...... (Rip)
It's Probably really early for anything since the phones just come out but was wondering if anyone here knew of a site thats run by Samsung or something that has retail roms to
fix demo models.
Any help is help, ive tried doing factory roms and everything but it just goes to Fail Modem on boot with unauthorized os.
Thanks!

Demo models, does normally not have modem.

This phone was likely stolen,why would a demo model be on the market already?
Besides,demo phones are basically useless,buyer beware............................

thats what i told him lol, i said id give it a shot but no promises.... Its making a nice paper weight on my desk right now tho.

im sitting here with 2 demo unit Note 9's. A friend used to work for a company setting up displays in stores. She quit the job but still had a box of "stuff"...tablets, phones, accessories...any hopes of using these Notes?

I bought a phone off amazon, and it was locked. I followed this video and made sure i downloaded the right files for the phone. They are posted here somewhere..
Here is the youtube link for hardreset.info
here is the firmware link

I have same model : SM960XU
And same problem, after flash : it's stucks with green screen with SECURE CHECK ERROR : MODEM.
did you fix your problem ?
can anyone help with it ?

Hey Guys,
First of all for the toads living inside the well who hasn't seen the outside world: A Demo model isn't always necessarily stolen. These are given by samsung for earliest testers and or app developers whom are sponsored by Samsung. Also, When the Product reaches EOL, Samsung never collects them. Those are usually distributed among the staff, and or close associates of the store keepers. You'll see them a lot on eBay, But never pay and obtain one - because that might be stolen. If you are receiving one from a legit source for no payment, Nothing to worry. These Demo's are never sold, and are always distributed or placed in stores for free. Also, They have a tracing app which shows where they are placed, on which date and by whom, along with it's power on/off state, and a separate FOTA Server for Demo content to be downloaded.
For the Solutions: You can always flash them with the regular firmware once you identify the CPU Type. Install an app like CPUZ from an OTG, and then run it. Check the CPU type (Snapdragon or Exynos).
If it's Exynos it should be N960F firmware, and If Snapdragon it should be S. I'm not so sure about Snapdragon, but the surest way to verify this is check the units which are sold to customers in the same store. Demo's are usually based on the region.
When flashing through Odin, You can load all 4 files, the modem won't be rejected if it's the same CPU. (I've done it numerous times for Exynos devices). Before flashing, Make sure to tick Nand-Erase option in Odin, and Flash it away.
If You've screwed up the device to a potato state with Download Mode, Download the firmware files from a Paid Site (Won't link them here, You can Google for them using the firmware code on the demo device).
Hope this info helps you mate, If not or if you need more information - Send me a PM with the Questions.

Thanks for answer. Fully agree with you about low IQ people who think Live Demo Unite - it's "probably stolen unite .." ...
SM-N960XU
1. if some one have this model , do not flash it before you go in to "retail mode app" - and enter login and password - to disable ( not remove ) - retail mode...
login and password easy to find on itnernet for free.
2. i didnt desable retail software before going to flash my note9.. and this is problem... now , knox loader - wont start new firmware.. all flashing going well... Odin say nothing , but ... green sreen and "security error - on restart"...
Nothing helping.
- wiping cash - not helping
- wiping to factory settings ( from recovery ) - is desabled by MDM ,
what is MDM ?
MDM (Mobile Device Management) Policy is a software package that Samsung will supply enterprise. The companies want use smartphones and tablets as a tool to support their employees but they want to limit some functions such as Camera function is disable, Browser function is disable...and now, my team will solve "MDM does not allow factoryReset"
----
well... nothing helps.
but here some interesting finds...
Demo Unite model is : SM-N960XU
It's was surprise for me, but same model name is for regular Note9 is also ..
SM-N960XU
Look at this :
.samsung .com /ca/support/model/SM-N960XZKUXAC/
visit page, and you see "SM-N960XU".
but URL states : SM-N960XZKUXAC
If i am understand right , this is full name of regular phone ?
SM-N960XZKUXAC
so i am probably need to look for some firmware for SM-N960XZ ? Corrert ?
--------
Anyway - what i will to try now, i want to install custom recovery. and from custom recovery i will wipe system and install fresh firmare.
i think custom recovery will replace - samsung recovery what is blocking phone from starts new firmware..
but only one problem...
when i try to install twpr - ODIN3 - tells me : complete write operation failed
So it's means : knox wont let me replace it self..
WHAT TO DO ?

XDA doesn’t allow this kind of posting as it’s a grey area!! Stolen or not! None of you can prove you purchased via legit mean?? As even Samsung does not sell them so how can it be legit?? And don’t say eBay/Amazon it can be stolen and resold on there! So you can kiss those theory goodbye!!
That’s why they don’t have modems, as Samsung did not release them for the general public! You can’t bypass no matter how much you flash it! Mods shut this thread down before someone grows some i.q! LOL
