Hey guys,
I bought a phone off of Craigslist and it appears that the phone is locked with a password. I tried to go through the bootloader and do a factory reset but I get a message that the MDM Does Not Allow Reset or something along those lines. I have also tried to use Odin to flash a stock recovery, that goes through successfully, but upon starting up the phone it appears that the password is still locked to the phone and nothing changed.
I tried calling the person who I purchased the phone from and there is no answer, so at this point I feel like I lost money and cant use the phone.
Please help

The above post is correct. Odin will be your only option, although keep in mind that "MDM" stands for Mobile Device Management, it's what large companies and schools use to manage devices remotely to install updates and such, kind of like Microsoft Active Directory . Did your Craigslist source seem a bit shady? Because if that phone is linked to a MDM account and it was stolen and currently turned on, it's very likely that someone is going to track it down using it's data connection and gps.
Hi to everyone. I have a Samsung Tab S2 SM-T810 with Android 5.1.1 / Kernel 3.10.9 that has retail mode on, it was a demo in a store. Is there anyway to remove this from the device? I already try doing a factory reset with stock firmware and odin and it stills the same. I think it has some kind of software installed on the ROM memory that prevents it to fully restore and wipe the retail mode app. Thanks in advance.
Please do a search this has been covered plenty of times already. There is no need to repeat over.

It's simple, make sure OEM unlock is enabled in developer settings, Install twrp, factory reset with twrp, boot to download then flash stock Firmware.
Done.

I wouldn't be asking for help if it were that easy. I tried doing that too. All the option in the developer settings tab are gray. I can't change them. The retail app is blocking it.
Any other idea ?

Just go ahead and install twrp and continue with the previous instructions. If you get the FRP block, just flash the stock Firmware.
Also if you carry on with the attitude you're on your own.

Excuse me, I didn't mean to offend. I'll try to install twrp right now.
As I expected while I was trying to install twrp it always return an error on Odin so I gave up, then after a couple of hours the table ran out of battery and since it was the first time it went off without the retail app monitoring. I decide to boot it into download mode. and that's it.
After that the twrp finally got installed and I erased everything on the tab. after that that it got stuck on the samsung logo. And I could install the stock firmware with no problem.
All thanks to you.
Ok so ive got the Sm-810 and i was experiencing the same issue of it not letting odin flash to stock OR install twrp etc. etc. and i was going to give up and i **** you not i was trying to get into the recovery to see if i could jostle some solution loose and it fixed itself !! It was booted into download mode and i unplugged the cable and pressed and held power+vol down and as soon as the screen went black i did the same thing again and then i mustve messed up cuz it booted into the os but i repeated the process from there and no kidding after 2 or 3 cycles of power+vol down i got a blue screen with an android on it and it flashed and showed a dead android with the caution! sign and the next screen showed the regular android with the word "erasing" underneath and vio'la no more retail mode. After this Odin worked and let me autoroot and so on an so forth. sorry for my long post i just though i should share
I think the major issue is that OEM is disabled and there is no way to turn it on. So most of the solutions are a no go... So any other suggestions on make this work?

Hi huntejes,
I've a SM-T650NU unit and have the same issue you faced on the Odin step (of course I'm using the specific TWRP file for my unit) just want to know what error showed up. In my case it returned: FAIL! (Auth).
Will let the battery fully drain and after that repeat the TWRP flash. Do you remember (step by step) what you did after the battery drained? I mean charged to 30% then put on download mode? Any feedback will be appreciated.

My husband and I also ran into the problem of having our Samsung Tablet E nook 2017 model stuck on Retail Mode.. we tried EVERYTHING we could possibly think of after the 5444 password didn't work. We rooted, we downloaded "easy uninstalled" apps, did the hard reset with the 3 button deal.. nothing! Then we finally came across a few passwords we were willing to give a try.. so when you go to the retail mode bar and it prompts you for a password to uninstall try blue. The word BLUE but in lowercase.. and it worked! We were then given tons of options and finally got that crap off our paid for device. I'm 100% sure that any device purchased from Best Buy and stuck in retail mode will use the password blue. A few other passwords we came across that might be worth a shot if blue doesn't work are: galaxy and unlimited. (Each by themselves as one password) Well good luck, we know how frustrating this has been!!

Dude, I have a SM-t560nu and I feel your pain. For months I was trying to find a solution and had to deal with obnoxious fools who couldn't get it thru there heads that this was NOT the usual Samsung Retail Mode but a special piece of software that puts the tablet into a rolling cycle of 2-10 minutes, shuts off all developer options, locks frp and basically makes anything you do null and void. I tried every password Imaginable including "BLUE," "5444" and the oft repeated "M729Q16K8546" all to no avail.
Here's the deal: this IS unique software and you'll find it at retailsamsung.com. (I can't post the actual url because of the new user rules, which is kind of funny because I've been a member for about 10 years but I don't think I've ever posted anything.)
Go there, search your device and download 2 items: One will be your installation package (for instance "Samsung_Retailmode_Global_Common _141006.apk") and the other will be called "RetailMedia.main." Download both to na sd card, put the sd card in your device, move the programs from the sd card to the download area ON the device. Now start your device, got to the download area and tap on the first program, the apk. Enter 5444 as your password, follow the instructions. the second password will be "M729Q16K8546." This will remove the Retailmode software and most likely trigger a Samsung lock. Go to Sammobile, download the original firmware and congrats, your new tablet is finally working right.
I was wary of downloading software from such a plain site, especially one I've never heard of but I figured after 6 months of no luck and my new tablet just sitting in a drawer, unusable, what did I have to lose? Well, it works, i'ts awesome and it's like new.
Hope this helps.
Mfb5159, You Are Awesome! A friend entrusted me to remove the Retail Mode from her Samsung Galaxy Tab A 9.7. I tried Everything. The passwords that can be found everywhere online, circumventing the FVP (of course that was useless), downloaded & installed the firmware with Odin in download mode... nothing. Then I ran across this forum. Tried two versions of retail mode from RetailSamsung.com and the second one worked. I had to open the retail app I installed, enter the generic passwords (5444 & the M729Q16K8546), then it gave me the option to factory reset the device. I chose yes & it worked! No sign of Retail Mode on the tablet. It's like a brand new tablet!! The .apk file that worked for me was SamsungRetailMode_GlobalCommon_141006
Thank you So Much for your help.
I hope I'm not posting on a dead thread. I saw a good deal on a T813 in retail mode (will provide link if needed, it's on a very popular and legal south american online store). The thing is, as explained by the vendor, someone attempted to remove the retail app and now is stuck on a countdown in the lock screen. After some time it reboots itself. I've been reading a lot about the topic and the main problem seems to be the OEM unlock off. Now apparently I won't be able to access any feature of the device at all. I thought maybe I could reinstall the retail mode and get back the app or just boldly odin flash twrp and a stock rom risking myself to an FRP lock.
However I thought better ask advice first, so what do you think? Any help is greatly appreciated.
Well, I bought it and first day has been no success. I can access guest user, could log in to my ggl account and downloaded some apps. OEM, third party apps and developers are out of reach and cannot access main account. No sign of retail app.
Flashed new stock rom, FRP asks for a password, tryed 5444 Mz$%"#$%& blue galaxy unlimited with no luck. Attempts to flash twrp via odin fail due qst (?) error. I guess because is OEM locked. Flashed some older rom and still a countdown that doesn't let me in in main account.
So far, this is my progress with it. Any advice to flash twrp, remove frp lock and/or remove retail mode? Thanks in advance

Did the same, although I had to use the older ap_SamsungRetailMode_Global_Tab_A_L_v1.0.4_15031100_M15031100_P0.apk with my SM-T550 (Galaxy Tab A (2016) 9.7") - I also had to stop the existing RetailMode Service from running by opening applications, swipe across to Running Applications, and tap on the Retail Mode executables to disable the "Sta" service. Annoyingly if you accidentally get the password wrong then it'll reset itself and delete the newer APK and you have to start the whole process over again
Could anyone at least point me in the right direction please? I can't access the main user of the tablet because there's a lock on the screen saying "Try again in 1440 minutes" which is a day. It self reboots every 5 minutes and each time the 1440 minutes thing resets. I booted in safe mode, now it doesn't reset and countdown is set for the next 4 hours.
Please, any light on the matter will be great. I have 4 days to return and I wouldn't like to do it cause it was extremely cheap unless, but I don't want to end with an expensive brick either.
Huntejes,
I had the same experience as you with my SM T810. The particular version of the Samsung Retail app (com.samsung.sta.retailagent.lite 6.9.20161101) installed on my unit didn't have a 'configuration settings' option; instead an option called 'Store Settings' prompted a password entry - but admin passwords 5444, blue, galaxy, unlimited all failed.
So then I went the Odin/flash stock firmware route. Unfortunately, despite two rounds of that, the Retail Mode application and restrictions remained. However, what did arise from this seemingly pointless process was the ability to enable installation of third party apps under Settings - all other admin access and functions (i.e. factory reset, program uninstallation, etc.) remained under the restricted control of Retail Mode. I went through that process about a year ago, assuming I had failed - the restrictions remained, and I was out of ideas/options.
Two days ago, I decided to revisit the problem, having to reeducate/remember what I had done previously along the way. Eventually, I came up with a novel workaround that hadn't occurred to me before - side-loading an apk file containing a different version of the Retail Mode software. Ironically, this worked. After installing and running the alternative Retail Mode app, using admin password 'blue' I was able to uninstall the original (i.e. problem) Retail Mode app, enable factory restore, and execute a complete wipe, which was successful.
I know this thread has been silent for a while, but it was one of only two threads that I thought took the larger conversation beyond the first basic step and I thought that contributing to it would be a small way to express my thanks.
Cheers.

So thank you, mfb5150, for your post - had I seen it earlier you might have saved me an hour or two of trial and error. It's interesting to me that this thread has finally reactivated after having gone dark by the time I came across it back in 2016. I'm not a developer, and have no programming/coding experience, so I hope that this thread continues to be a resource for any others like me out there.
Hi guys,
I have a galaxy tab and sm-t561, which presents the problem of retail mode that you can not remove in any way even with odin, I wanted to ask, how do I install a version of retail mode via apk? I downloaded the new version of retail mode but how do I install it?

i just follow your instructions and awesome mine is unlock now and downloading the update to android 7.0 thanks bro
So I bought this phone from eBay, like many before it. But this time it came with a twist: when I booted the phone, initial setup ran and all wend fine until I got to the register Google account screen.
There, the phone says: "This phone was reset. To continue, sign in with a Google Account that was previously synced on this device".
No matter what account I use, I always get a Toast message saying "Unable to sign in to device due to a unknown error. Please try another account or try to sign in again after 24 hours.".
I'm guessing this is some kind of theft protection where entering a previously synced account "proves" that you're the legit owner. The authorised service here told me that I need some kind of proof that I'm the legit owner and surely enough the eBay seller has issued no invoice containing the phone's IMEI (or any similar document).
Anyway, here I am with this gorgeous phone on my hands which is little more than a brick due to this.
Is there any way I could get it to work again? Returning it will just generate more costs for me and I'd like to avoid that.
I've seen guides on youtube where they managed to bypass this security measure, but both methods I've seen failed for me. I guess the version running on my phone is just too recent and plugged all the holes.
Do I have any way of downgrading the software at least? Note that this is a fully locked phone and I can't even start TWRP from fastboot.
Anything else?
Edit: Now that I'm re-reading this post, it occurred to me that there's very little chance that this phone wouldn't be a stolen one. Had it not been, the seller would easily issue me an invoice.
Leaving this post only because my searching hasn't turned up anything on XDA. Probably also reporting the guy on eBay.

From the Settings / About, what is exact (full) build name/number?
Generally, if you are on Nougat then IMO, rolling back to MM should completely reset your phone.
You cannot flash TWRP without unlocking Bootloader. But that will not help much for resetting Google protection.
Btw, enable Developer's menu, does it allow you to unlock FRP/OEM Unlocking - in that case you will be able to reset all from EMUI recovery.

It is stock recovery. I don't recall the option for factory reset. In fact there's no options at all, save for reboots.
Fastboot says everything is locked as it should be.
Don't know how to downgrade to MM.

Rollback instructions are here
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
But not sure would it allow you to setup.
That is Factory Reset Protection (FRP/OEM Unlocking) - if it was unlocked you would be allowed to reset from recovery.
You can ask seller - maybe he can login to his Google account and remotely remove Google account from the sold phone.
Or you can try DC Unlocker, not sure would it work
https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
Well, DC unlocker ultimately worked, but not before buying a wrong package, having to ask tech support, etc, etc. Not to mention the guy really has no patience for people who don't have his level of understanding of the subject. Why does he do it then if he hates the whole thing so much?

Sorry for bothering but I'm interested now - when Bootloader was unlocked (and FRP too), were you just able to pass setup or you needed to do Factory reset from Recovery or how did you get the stock ROM working for you
Final resolution: the seller sent me an invoice. I guess that means that the phone wasn't stolen after all since they can only expect that this will be entered into Huawei databases.

The procedure was thus:
1. unlocker unlocked the FRP
2. phone rebooted into a factory reset (low level) mode - it specifically said "low level"
3. phone booted into normal Android where the FRP protection was no longer active. On screen where it previously demanded a previous Google account it now only demanded A (any) Google account as I'm used to from all the other phones I ever bought.
Sorry old post
