Device Unlock app not working - T-Mobile Samsung Galaxy Note 8 Questions & Answers

Phone was unlocked (via device unlock app) a few months ago. Then I switch over to the unlocked firmware. When the phone had a defect I flash the phone back to a T-Mobile firmware and sent it in for warranty repairs. The phone came back after repairs (replace main board) but is since sim locked again to T-Mobile. IMEI is still the same as before. I tried to use the device unlock app to unlock again but it goes straight to "device not recognized by your service provider". It does not behave like previously where it goes to option of Temporary Unlock or Permanent Unlock. T-Mobile have already requested my IMEI unlock again like they did previously but nothing works. They said that if you can't get the app to ask for Temp or Permanent Unlock then it will not communicate with the server.
I have the latest firmware already, CRE1.
So far I have clear cache and data on "device unlock" app, clear cache and factory reset on recovery, reflash the latest T-Mobile firmware. All have failed to get this "device unlock" app working properly again
Does anyone know how to get this app working again?

I had a similar situation with my phone that after being paid off would not unlock with app. After calling Tmo x2 times, technical help was the only way to get it to work. They probably have to manually release it on their system.

T-Mobile have tried on their end many times/things but still nothing. This is through T-Mobile technical, phone, social media, and chat. All same result.

S3 relocked?

I have a factory locked S3, but my provider gives out the unlocking code for free. I put in a sim from another provider, got asked for the code, entered it and it worked.
I then rooted the phone.
However, after a few days I wanted to remove root and reflashed stock firmware with Odin. I searched out the proper file here at xda and flashed it. I then got an error about messaging stopped everytime I booted and searched some more. The solution was to flash with Odin again, but check upgrade bootloader. After that the phone works fine and everything is in place like it was new.
But, my phone has been locked again and my code does not work anymore. I have called my provider (leaving out the root and flashingpart) and they say that if the unlock is not working I must send it to them so they can unlock it.
So I have these questions:
1. Having done what I have done, will TriangleAway + reflashing stock with Odin remove every trace of my "tampering"?
2. What can they do to the phone that I cannot do myself with som advice from xda?
3. How many attempts are there of entering the unlock code? It still asks for a code. I do not get any message about too many tries. But I have must have punched the code more than three times...
I have read that people get their IMEI changed when reflashing, but mine is still original. I can not understand why the operator lock has come back.
Please help!
1) I believe so yes (not sure, I'm new to this forum just what I've read)
2) They can block the IMEI if the phone was lost/stolen
3) I am not sure with Samsung/Android phones but when I was unlocking my mums Nokia C3 it only allowed me to enter a code three times before displaying an error message.
It is not stolen or lost. I have bought it from my operator myself. I talked to them today and there is no block on this phone. It does work with my operators sim, but no other sims.
My question was that they can do to unlock ut that I cannot do myself?

Everything, they are your carrier.
None of us can generate unlock codes for the phone, they can get the unlock codes and make sure it's 100% unlocked

What about the Voodoo sim unlock app ? You'll need root access though. the app has also been removed from the Play Store
The dev's site, you can download and sideload the app from here:

That's not an unlock code though it's just temporary. A factory unlock is permanent (or so it should be)

I spoke to my carrier and they said that there was only one valid code for my IMEI, and that does not work anymore. It did work once, but after reflashing the firmware with Odin, the lock came back and now the code does not work.
Perhaps they just replace the phone with a swap unit? Therefore I ask again, will TriangleAway and reflashing stock remove all traces of rooting/tampering? If not I will get the phone back and be forced to pay for the service as well.
+1 for this problem.
I unlocked mine with the voodoo unlocker and was fine for a couple of months. Flashed a newer version of cm10 and was asked to enter Sim unlock code. This time I got the pin from my carrier but with that number it says Sim unlock unsuccessful.
Anyone else had this problem? Anyone know of a solution?
At the moment I just have a fancy mp3 player/camera :silly:
Voodoo sim doesn't work properly with then latest firmwarea but theres a new app 'Galaxsim-unlock' that I can recommend. Your'llshare find it over in the themes and apps section

You can try to use Valhalla ( Voodoo has disappeared from the Play Store ) :
http://donmacsblog.blogspot.co.uk/2012_06_01_archive.html?m=1
I've managed to get mine back to unlocked.
I was on cm10 and then when flashing a newer version the lock came back. I was originally using voodoo sim unlock but that wouldnt work this time so rang my carrier and got an official code which would not work either.
Flashed back to stock using odin making sure to use the network branded ROM i was originally on and not just a stock ROM, then enter the code the carrier gave me and this time it worked!
Guessing you must be running a stock carrier branded ROM for the code to register properly and unlock.
Hope this works for anyone else!

unlocking h901 t mobile?

yeah, it uses the device unlock app.no it says i'm not eligible for unlock.the seller who sold it to me even requested tmo and was denied.tried rooting and messing with system files now it says can't connect to remote server even after reflashing stock using LGUP.Tried using the f600l rom port, no you can't get the sim unlock prompt to pop up.tried blisspop and resurrection roms, they do prompt for a sim code but the codes do not work it says 255 retries remaining<<<something not right there.I do have the right unlock codes, just get them from an unlocking site or ebay.Speaking of unlocking sites, they want 60usd+ to unlock the tmo variant WTF!! Also if you try to get into the sim unlock menu using stock rom (dial 2945#*901#) it just says device permanently locked for everything.Now if there was a way to get a stock rom or port from say at&t variant which has the sim unlock prompt it just might work.
The closest i've got to unlocking this thing i the actual network unlock screen that comes after you flash the stock firmwire through LGUP. it said 0/30 attempts or something for a brief second or two the first boot after reflashing and then it restarts before you can even do anything into os never to be seen again unless you reflash it again but again you will only see it for a second and its gone again.I wonder if there is a way to keep that screen on so you can attempt to unlock it via code.
Also I'm pretty sure the device unlock app is just there to check prerequisites of your t mo account.In reality it does unlock the same way as other phones.probably just applies unlock code from tmo database once it checks you've met the criteria for unlock.
t-mo has really locked these down .
So has anyone been able to successfully unlock this phone without the tmo app? or have a cheaper service to unlock this thing ? Else im stuck with a paperweight.

I have tries on UL40 many different rooting apks and through pc. Most say root fail or your phone doesn't seem to be able to root. Any help would be appreciated. To root the ANS UL40 and also how to flash over Note 3. I have done flashing before on a note 2. So i basically know what to do. When I did try to flash over the note 3 I just get your account cannot be verified when calling 611 (without the sim) but when I insert sim its says no sim or sim locked reboot phone. Thanks

Hi,
My friend just got the same phone and while setting it up for her I noticed that the default file manager is called CyanogenMod File Manager. It's probably meaningless but thought I'd share it just in case there's some sort of CyanogenMod back door. Good luck and if you do get it rooted please let me know.
I found a paid root that will root UL 40 Assurance choose the 6 mo lan.. https://www.oneclickroot.com/support-packages/
I wouldn't have asked on here if I wanted to pay for it, and they are not a guarantee they can do it. have read somewhere that someone ask them to do the same phone and they could not............ And no still no root. Probably does not matter. Talked to Assurance wireless rep today and they said lots of people are complaining about this phone. I have had in less than 2 weeks of getting it, had to have them warranty it and they sent me the same one. It would reboot on it's own and yes did factory reset. Now have the replacement, haven't done any kind of rooting or anything and on day 2 it starting to not be able to make phone calls. Says phone is not responding. Did a factory reset on this one and still doing same thing. Sometimes it does make a call and sometimes not. Pissed I am....
I stumbled across a site. Idk but it looks like it could contain some valuable info you may need or may be looking for. Send me a message or email me for the link. Since I've not posted before, it won't allow me to post the link.
I have decided to go to another provider for my cell phone and the UL40 phone will be no more. After talking to them so many times and finding they are complete idiots. Because they keep sending me a phone that stops working correctly after 1-3 days. Even before I started trying to root. I even talk to a real English speaking (LOL) person and they told me what I already knew, the ANS UL40 phone is a complete piece of ****. So many people have complained to them about that phone they decided not to ship out anymore. Now what kind of phone i will get from other carrier, I'll have to wait and see. Thanks all.............

I was wondering if there would be anyone nice enough to make a custom ROM for the ANS UL40. I would do i tbut I don't have the coding skills or patience to do so.
ANS UL40 "Cast" compatibility w/Actiontec ScreenBeam Mini2
Asking if ANS UL40 "Cast" will run Actiontec ScreenBeam Mini2.
UL40 is "CAST" standard compatible with Mini2 (WiFi Mirocast and INTEL WiDi certified) ?
UL40 able to PARE WiFi and update Mini2 firmware. UL40 says CONNECTED, but click "CAST" and phone goes back to WiFi. Mini2 screen says Connection Failed.
If able to preform firmware update, then UL40 is communicating w/Mini2 so, UL40 should be compatible, but "CAST" fails.
Please advise.
Many kind thanks.

Hope someone can figure out how to gain root access on this phone I have it and It would be a blessing
you can unlock the bootloader in android dev settings "OEM unlocking", once in bootloader cmds like "fastboot oem unlock" or "fastboot flashing unlock" do nothing when connected with usb, what a shame. In recovery (vol up + power) there's an option to mount system, it does but I doubt that can lead to anything root access wise, btw, root noob.

Could you elaborate!?
In which market are you in?
It seems to me that they are still shipping it in many markets Assurance Wireless is in, like Oregon for example... so how did you come by that information?
I got this phone a couple days ago and got my msl code by running adb logcat while dialing ##data# and entering the wrong code, it was 536978 and used this on DFS to change it to 000000 then I was able to access everything once I entered ##diag# and then 000000, and enabled diagnostics. If I can get a working stock firmware or boot IMG I could root through magisk and then do separate fastboot boot (magisk patched)boot.img. I am unable to find a stock firmware for this device if anyone can let me know and I'll have root for us.

Issue with unlocking - Please help

Hello,
I have an SM-N950U from TMB which was purchased direct from Samsung when it was just launched after the whole debacle of the Note 7.
Phone has been working fine on TMB this whole time. Today I switched to VZW and attempting to have the phone unlocked.
I tried to use the Device Unlock app on the phone, with no luck. It fails when I try to Permanently Unlock the phone.
I called TMB for assistance, they said that the manager has tried to process it manually and has been unable to do so after multiple attempts. Escalated to higher support who got on the phone and said she's unable to help and does not know why it is not working. Said she will be escalating to a higher support group, but as of yet, nothing from anyone.
Is there any way of unlocking this phone without TMB?
I've attempted to flash VZW via ODIN, both U and U1, with no luck. I also tried the U1 XAA and still the same thing, I get a message "Network locked SIM card inserted".
Any help would be greatly appreciated as I am at a total loss and want to continue using this phone as I've been, just with VZW now.
Side note, maybe it's failing because the phone is already unlocked, just doesnt work with VZW? Not sure if thats a possibility, but is there any way to check to see if the phone is in fact unlocked or not?
Anyone?

Tab S6: Factory Reset with Stock ROM and still getting "protected by Knox Cloud Service"

Recently purchased a used Galaxy Tab S6. I was warned it had a warning about the bootloader being unlocked. No big deal. The seller couldn't remember his Samsung account credentials so we couldn't factory reset at time of purchase via Settings. No big deal. I went into Download Mode and relocked the bootloader. I went into Recovery Mode and Factory Reset.
Then I ran into "This tablet is protected by Know Cloud Service. To continue setup, connect to a wi-fi or mobile network." I've done that (since I can't skip the step) and get the dreaded "Can't create work profile" error and that's as far as the set up will go.
So I used Odin to flash the latest stock ROM and factory reset again and wiped the cache and I'm still having that problem.
In download mode, I've confirmed that Knox has been tripped.
I've googled like mad and I'm not finding a solution. Can anyone help me out? I'd prefer to stay on Stock ROM so there are no hardware issues (particularly with the SPen) as I'm planning to use this device extensively for note-taking (with OneNote). However, I'm open to custom ROM if that's my best/easiest/simplest route.
Thanks in advance!
If you're able, unlock the bootloader again. When you flashed with Odin, did you use the CSC or HOME_CSC file?

I used CSC. As I understand it, that is the "deeper" reset option.

Correct, that wipes user data.
Unlock the bootloader again, which will wipe the device (again), and see if it's removed the FRP. If not, you should be able to flash TWRP, from which you should be able to flash this to disable the FRP.
I can't access the developer options because I can't get through the setup wizard. So I can't flip the OEM Unlocking so the download mode doesn't give me the option to unlock. I can connect to ADB via the Recovery Mode but Fastboot doesn't see it so I can't do "oem unlock." Are there any other methods to unlock it? My friend Google hasn't found any yet.
Seller was able to login to both his Google and Samsung accounts and remove the device from them. That got me through the 100% Know Enrollment Service before it hung up in the "update" portion again. He was also able to send a message to the tablet from the Samsung account to try and release it further but, of course, since I've wiped it, that message can't get through.
I'm getting desperate. I might have bought a paperweight! Any once else have a suggestion?
Checked with the seller. He bought it from Kijiji as well from the original owner. It's always been a personal device, never an institutional one.
Last night's searching of the internet determined that the device is in "prenormal" status so I'm just going to wait 7 days and reboot. That might be sufficient. Nothing to lose at this point.
