[Q] Branded T-Mobile UK Samsung GLXY S 2

Hi everyone,
I recently upgraded to the Samsung Galaxy s 2 on T-mobile here in the UK. Obvisously it came with T-mobile's version of Android 2.3.3 . When the phone starts up or shuts down, it displays T-mobile's logo wallpaper.
The phones has an option to search for updates, but it can never connect to the server.
It does not have the option to sign into the Samsung account, it does not exist on my handset, only Google account and the usual facebook and others options.
As a result of this I don't have the option to use Samsung's mobile tracker. For those unsure google samsungdive.
I don't need to use other networks on my handset, just T-mobile. T-mobile have removed the tracking option so this is why I want to put Samsung's software on my phone.
My question or what I want to do is this:
1)Remove the current T-mobile Android software from my phone and install Samsung's Android firmware.
2)Have the option of signing into Samsung's account from my phone and be able to use Samsung's tracker.
3)Be able to update to the latest updates as and when available.
Please advise me as to what I have to do or what my best options are.
Thanks very much!

I would flash the stock version of JVR and use a custom kernel like semaphore etc

My friend can you tell which modem u r using on t mobile. Or baseband

Baseband version:
I9100BOKG1
I Spoke to Samsung about this and they said because I got the phone through my contract with T-Mobile, T-Mobile have played around with the software and some features are not present compared with buying the phone sim free with the Original Samsung software.
They said if I remove current software and put Generic Samsung software I will void warranty on the phone.
What do you think about this?
Thanks

I'd flash anyway mate, worse case scenario is if you get a fault, you can reset to factory using ODIN. Plus, I have a t-mobile s1 and it was flashed day of purchase from t-mobile, and even if you ring them, they aint really too bothered if its been flashed. Example, I flashed my brothers which played up, he rang t-mobile told them it was flashed they said well done, and would replace it if I couldnt sort it.....which I did.
In a nutshell....flash and dont look back!! Its really quite hard to'kill' an android phone!!

Hi, I have had the same issue as you. Basically if you have ever activated Samsung reactivation lock, you are screwed since the QC9 update wont let you past the google screen and if you go back to marshmallow it keeps saying activation failed. Your only option is to send it into Samsung and they will "unlock" the phone for you. I sent mine in and got it back two weeks later, unlocked.
Edit: my phone was out of warranty but they still took it in because its an issue with samsung reactivation lock, if the customer service rep gives you trouble, let him know that this is covered out of warranty.
Hope this helps!

thanks for this, I will try to send it to samsung service center in our area.

For me, the QC9 Setup Wizard screen kept bouncing me right back to the "Name Your Device" page, after "Checking for Updates..." It wouldn't let me past it. But it turns out it was just a case of logging into my Lookout account that I had forgotten all about: https://my.lookout.com/user/login and unlocking my phone using the directions here: https://personal.support.lookout.com/hc/en-us/articles/115000036533-How-do-I-unlock-my-device-
It had nothing to do with my Samsung account. Learned my lesson not to bother with Lookout, and disabled it as soon as I got to my home screen, lol.
Hope this helps someone.

S10 Trade In Program - Samsung claims I did not reset the device. Advice? Help!

I was hoping for an easy trade-in with Samsung. I have no flaws on my Galaxy Note 8, I sent it in before the date that they asked.
My screen had no issues, no scratches, perfect condition.
The phone turns on and runs absolutely fine.
The last thing I did before I packed my Note8 up was to take out my SIM card and microSD card and then do a factory re-set.
The final screen I saw was when it rebooted after the reset and was ready to start the process from scratch - which I have done before.
So what happened? Why are they saying my device was NOT reset?? This is absurd, I have seen people get no credit before for other things but never the "not factory reset"!
Can someone help me or offer advice? I have a week to call them before they charge me and I can have them ship the device back, but **I had a perfect condition Note8 and I want my $550 trade in!!**

I guess you didn't remove your accounts before resetting your phone. So, most probably, the setup process will ask for previous account credentials.
Samsung should be able to bypass this protection if they want. Or you can see with them the possibility to send them your account credentials to help them unlock the phone. If they refuse then they have bad intentions...

I can only imagine it is the FRP as this would require the setup to ask for the security details you had on the device prior to reseting the device and then the Google email address attached to the account, however this would only happen after a master reset so not sure if this is the reason, however when I tried to sell a S9 to a recycle site in the UK and I made this mistake they sent it back as I was not able to remotely do this.

Did you do your factory reset through settings menu? I sent in my galaxy s8 back to them for the trade in program Monday and it was running One UI beta 3 so I flashed it through ODIN using the latest Sprint firmware and CSC file to wipe everything back to complete stock. When I did the initial factory reset before flashing in odin I went though Settings > General management > Reset > Factory data reset. It asked me for my google password before it would reset the device. I did the ODIN flash to make sure everything was gone and it was on the correct latest Sprint firmware. I was afraid being on the BETA they may reject it. Now you've got me worried because I didn't try and set the device up again to see if it asked for my google password. I'm 99% sure when doing a factory reset through settings and entering in my credentials FRP is no longer active. Does anyone know if a clean ODIN flash using the CSC (not Home CSC) will remove any and all settings such as FRP?

I am a little confused as I removed my SIM and SD Card and then did a factory reset and it went back to the first set up screen. So, you are saying if we did not remove our Google account or work email prior to factory reset they could refuse the trade in??

Yes. FRP (Factory Reset Protection) is designed to deter theft by requiring any Google account (not sure about Samsung account) that was active on the phone at the time of factory reset be logged into prior to using any other account after the factory reset. You can disable FRP by just going into Settings -> Accounts and removing your Google account prior to a factory reset.

Maybe so, but I've traded two phones with no problems and all I've ever done is a factory reset from the settings. Both times I did reboot to see if it went to the default setup screen, but that's all I've done.

Same here, did a factory reset only. It was approved even with unlocked bootloader and twrp...

Well, I appreciate everyone chiming in...I hope ultimately they approve the trade or get you phone back to you so you can sell it to recoup your money...
I checked to be sure and it seems my trade in was excepted as they only charged my Amex the discounted amount and they received my trade in on the 28th of March and i did not do anything but a Factory Reset... same thing when i traded in my S8 for the S9...
Maybe Sammy saw something questionable on the unit and used this as an excuse to deny the trade? It could be possible that this deleting of the prior accounts is in the fine print somewhere and they use when needed?
Best of luck...

I think you're at Samsung's mercy in these situations. You can complain to them until you're blue in the face, but in the end it's at their discretion.

Yeah, there was nothing wrong with my phone so I am going to complain pretty hard. I have hit up the Samsung Mobile USA and Samsung Support USA on Twitter before and retweet them enough that I hope to make a fuss that I can get taken care of.

Good luck. What's so bad is that Samsung isn't even the one's inspecting the phones. They should have some process that makes Samsung themselves look at a phone after Ingram Micro rejects it.

No Bootloader OEM Unlock Option?

I got the S10 recently, and when I went into developer options, the "OEM Unlock" option is missing. This confuses me since I ordered a Hong Kong model (SM-G9730) that supposedly allows for an unlockable bootloader according to people here and elsewhere. Would appreciate it if someone could help shed some light on this. If it matters, in Settings > About Phone, it definitely says SM-G9730 is the model, and under Software Information, the build number is G9730ZHU1ASBA, which is apparently the February 2019 build date.

Same issue
I'm getting the same problem. I am 100% certain without a shred of doubt that I have the exynos version but OEM unlocking does not appear in developer options immediately after developer options is turned on. From what I have noticed in my recent struggle to put this piece of ---- to good use, the OEM unlock option decides to appear after a certain amount of time after developer mode is enabled. Idk whose bright idea this was but if pissing off the customer was their goal then they did a stellar job.

I have this vague memory of reading that the oem unlock option is timed. So I went ahead and set the phone's system time to a month into the future (also checked 24 hour time but im not sure if that had an impact) to 7/9/19 while the phone was connected to wifi and now the OEM unlock option has appeared again. Hope this helps.

I have tried resetting the time trick a dozen times and OEM unlock does not appear. What is really frustrating is that it was there when I first got the phone and I had it turned on. Of course back in March, there was nothing you could do with the phone. Then bright people started to figure out how to root but by then, a firmware update had come along and OEM unlock disappeared. I tried to install Magisk but it failed badly. Now I'm stuck with the first phone/tablet I can't clean up all the unwanted crap I will never use or want. Very frustrating.

you need to wipe data, and when you set up your phone have wifi connected. Then it should appear in the options, if it does not change the time into the future

I have reset the phone back to a previous firmware version, which should have wiped the data completely. I enabled Developers Options right away but OEM Unlock was not there. I tried the time thing again, but to no avail.
Of course my carrier promptly wanted to install the last update which I accepted. Strangely enough, the phone is behaving better since I did this but I still would prefer to have it rooted so I could get rid of a bunch of junk apps.

Nope. I believe my carrier must have blocked it from appearing. I've given up all hope of rooting this phone and I'm learning to live with it the way it is. But this may very well be the last Samsung phone I have.

This is unbelievably unreal. All these versions and only two are unlockable? I have always bought my phones direct from the manufacturer to prevent a carrier from telling me what I could and could not do with my phone, now the manufacturer is getting in on it. A waste of $1000. However, I refuse to accept this mode of operation. I will perform better research and find a phone that gives me the freedom I feel I am paying for.
Thanks for the information guys!

Note: You have Internet to be activated. But first i would do all other steps. and then restart, do time sync, deactivate set 7+ days back in time (25-7-2019 > 17-7-2019)
DONE! UNLOCK OEM appers (at least in aprils version)

I just got off of the phone literally less than 5 mins ago with a Telus rep and we were discussing rooting (I'm in this forum wondering if there is a root method for the SD S10 version yet ~ I don't own one). He has the S10 and is waiting for a method to root it. We joked about how the Exynos version is inferior to the SnapDragon one. "Thank god we live in North America" he said.
So I don't know how you got the Exynos S10 from Telus. In Canada you should only be able to get the SnapDragon S10,

You're correct, I was mistaken in thinking the Qualcomm processor was the Exynos version. My apologies for that. Nevertheless, the OEM unlock switch is not available and has not been since the first updated firmware I got from Telus.
When I called Telus to ask about it, I got the run-around and essentially a non-answer. I have to believe it is Telus that is blocking this function although I've not read about anybody having this trouble who is with any of the other carriers. If you are looking to buy, you might explore this theory.

There is no root method yet for the SD S10.
It's not Telus, It's Samsung.
If you want root, don't buy a Samsung device. There will be a method eventually probably, but there has been a problem with root on the S line for quite some time now.
I would recommend a Pixel myself (monthly updates for 3yrs+), but there are other options out there.

Question Verizon S21 Ultra Locked and not unlocking

I appear to be in one of those samsung lock horror stories. I purchased a paid off verizon s21 ultra that was suppose to be unlocked but after i put my tmobile sim into it works for 5 minutes perfectly then an error pops up saying unable to change carrier call verizon customer support. So i did long story short i got no where. So i filed an FCC complaint and got in contact with a verizon executive and he got in contact with who i bought the phone from and they provided all the paperwork proving it was paid off and he reprocessed the unlock request and said it will now for sure be unlocked and it didnt unlock so i contacted samsung like he said for me to do if it didnt so i did and they told me to wait 48 hours for it to process. 48 hours later guess what its still not unlocked so i call samsung back and they said verizon still hasnt released it supposedly and there is nothing they can do and i need to go back to verizon. Im stuck in an endless loop of verizon executives telling me to call samsung and samsung telling me to call verizon.
What is there left for me to do now? This is stupid why is it not unlocking... The only thing that i can think is left is that the phone is flashed with stock firmware and not verizon firmware to remove the bloatware. But that seems like it shouldnt matter. Also the phone never asks for an unlock code it just says call verizon customer service.

It's more a Verizon lock horror, not Samsung.
Flashing other FW won't solve your issue.

First, did you verify that the unit is paid off?
Second, do you know anyone that has verizon?
Don't know if it will work, but I would try flashing the unit back to stock Verizon firmware and finding someone who has a verizon sim card.
Verizon units kind of unlock on their own. It is troubleshooting I would try because I do not believe the unit will unlock on U1 software on its own. Once it can get unlocked then flash back.
I suggest someone who has a verizon active SIM as it may help in it unlocking even though you can connect through WIFI

The verizon executative said it was guaranteed paid off and he unlocked it remotely again. But it does have u1 firmware on it im guessing i need to use frija and download the vzw firmware? And will another unlock request need to be processed again? And none of my friends have verizon due to how much of a ripoff they are lmao but i can have another verizon demo sim put in at another verizon store. I feel like i would have to file anpther fcc complaint just to talk to another verizon executive.

I believe for it to be unlocked or at least go through the process, the verizon U package is what I would flash, but you may be in a little bit of a issue if you don't have a verizon SIM on hand, even if not activated.
There are multiple ways to get it to flash back to U. I would use a patched ODIN and just flash the appropriate files from somewhere like samfw.com
If he sent out the remote unlock, it is very possible that once you flash back to U verizon package and connect to WIFI and go through the setup process etc. It may just unlock on its own. If you do not have a Verizon SIM card, leave your SIM out of the phone while going through the initial setup. You will need WIFI.
I would start with a clean flash just to be safe.

You literally quoted the answer

Verizon firmware has an app called "Network Unlock". Perhaps at the 60 day mark, the phone automatically unlocks. However, if on the unlocked U1 firmware, there is no framework to remove the lock. It'd be interesting to see exactly how the Verizon unlock process works.

It is somehow tied into their U package software and I am assuming unlocks it at the modem level in background processes. It's like the "signal" they send out can only be detected on their U package. I've seen it many times where Verizon phones automatically unlock themselves when restored to original package from U1.

I can confirm this works on my s21+ that was on verizon network, and was supposedly networked unlocked. Service carrier software said vzw/vzw, vzw/vzw. Tried to switch to tmobile with no luck with sim card swap. 5 minutes, error message about cannot which carriers, please call Verizon. Was on SM-996U1. So I tried to flash to SM-996U1 TMB, then SM-996U1 VZW, then, SM-996U1 XAA. No luck. Then I flashed, hesitantly, with SM-996U VZW . I thought that would put all verizons bloatware on it. Reseted phone and it did put all verizon bloatware on it. Then the magic! I installed my new tmobile sim, and a message appeared and asked if I wished to switch carriers. YES!!! phone rebooted to tmobiles network with no verizon errors. I checked service carrier software and it was TMB/TMB, VZW/VZW. I flashed phone again to SM-996U1 XAA. I rebooted and service carrier software was TMB/TMB, TMB/VZW! I then checked for software update, took update, and all it good! Thanks for all the information here. Took me days to find it and understand it and try it!!

Hi, folks. I am facing the same issue with my S21 5G (SM-G991U). I am also told that the phone paid off and clean. I am not sure what version I am on currently. I have tried SamKey, but that didn't work. Any help would be appreciated. Thank you in advance.

Does your device boot up Verizon and have all the Verizon apps?

I can confirm this works on my s21+ that was on verizon network, and was supposedly networked unlocked. Service carrier software said vzw/vzw, vzw/vzw. Tried to switch to tmobile with no luck with sim card swap. 5 minutes, error message about cannot which carriers, please call Verizon. Was on SM-996U1. So I tried to flash to SM-996U1 TMB, then SM-996U1 VZW, then, SM-996U1 XAA. No luck. Then I flashed, hesitantly, with SM-996U VZW . I thought that would put all verizons bloatware on it. Reseted phone and it did put all verizon bloatware on it. Then the magic! I installed my new tmobile sim, and a message appeared and asked if I wished to switch carriers. YES!!! phone rebooted to tmobiles network with no verizon errors. I checked service carrier software and it was TMB/TMB, VZW/VZW. I flashed phone again to SM-996U1 XAA. I rebooted and service carrier software was TMB/TMB, TMB/VZW! I then checked for software update, took update, and all it good! Thanks for all the information here. Took me days to find it and understand it and try it!!

From my experience, Verizon phones will not unlock unless on the U package, the U1 never allows the unlock to be processed.

It does not boot up with Verizon but it does have a few Verizon apps included (it has Call Filter and Digital Secure) installed. The current version of the software is G991USQS6EWD5. Service provider version is SQOMC_SM-G991U_OYN_SPR_13_0020 SPR/SPR,SPR/VZW.

Are you using this phone with Verizon service? From info you provided, your phone thinks you are using Sprint. It's a SPR CSC. You need to change the CSC to VZW. You need to bring the phone back to it's original state for any attempt of the unlock "processing".
