Any luck with this? I am thinking about buying a Sprint A50 (SM-A505U) and flashing it with the T-mobile firmware (SM-A505U1) TMB. Wanted to see what your experience was before I made the purchase. I need the phone to work on T-mobile.

Verizon Note 8...T-Mobile sim - help

Hello all, new here and I just purchased a Note 8 from Verizon. The device is paid off fully and i wish to use my T-Mobile simcard in it but it does not seem to be picking up a signal. I did update the verizon software to the latest version when i had my verizon sim card inserted. Verizon customer service told me i need to reset to factor setting then my t-mobile sim should work but this has not helped.
How can i get my t-mobile sim to work? Any help appreciated as i am new to android phones!
Thanks
Hi there, you must flash the new N950U1 2BQK1 or N950U 2BQK2 stock firmware to have full access of T-MOBILE Network. It's the only way it will work, I have AT&T NOTE 8 working on Verizon network with zero problem.

It's a very easy process to flash the 4 US Carriers firmware, I have done it more than 50 times and I'm not a developer.

I would like to know where to get the firmware and with what do you flash it with? Is there a instructions thread or link.
It's been over 5 years since I have tinkered with a Samsung device.
Hi there. You'll need to have your Note 8 Bootloader version on level 2, meaning 2BQK2, 2BQJA or anything with 2 before the last 4 digits.
1) tmobile SIM card in device
2) Odin v3.12.7 make sure extract
3) 2BQK2 firmware extract all files
4) put all 4 set of firmware files in the right manner, bl,ap,cp and csc. Don't used home-csc only CSC.

Unlock firmware
1) any carrier SIM card
2) Odin v3.12.5 Prince Comsey or modified Odin, make sure extract
3) 2BQK1 firmware, extract all files.

First instructions is for if you want stock US CARRIER BLOATWARE FIRMWARE, second instructions is if you want SAMSUNG STOCK FIRMWARE. Follow steps and everything will be fine, happy flashing.
So wait, I have a Verizon Note 8 (currently using MetroPCS perfectly), but I wanted a stock Samsung ROM (without the Verizon crap on it), I can just flash the second set of files instead and done with it?
Yes
Can I use a gsm sim card and a verizon sim card at the same time on verizon branded phone? I see you have to flash the firmware above but am wondering if this would help me.
So much misinformation in this thread.
I don't even know where to start:
The OP was asking why his T-Monile SIM wouldn't work. It doesnt matter which firmware you're on, if the Note 8 is unlocked (the Verizon Note 8 IS unlocked), and it has a clean IMEI, and your SIM is already activated, then it will get 4G LTE. I know. I have a Verizon Note 8, and use it on Tmobile. I used it for over 24 hours with my T-Mo SIM but running thr Verizon firmware with no issues. Only reason I flashed T-Mobile firmware was to rid myself of Verizon bloat and to get wifi calling.
As far as bootloader, that has no effect on the SIM card working. The OP would need a v2 bootloader firmware if his current firmwarealso had the v2 bootload. It probably does, so thats a moot point, but the implication was the v2 bootloader was the only one that would make his SIM work.
I hope the OP got it all figured out.

plus the second SIM wouldn't have an IMEI assigned to it.
And I agree the OPs best bet is to flash thr T-Mobile firmware. But his issue was he wasnt getting a signal at all with his T-Mo SIM. Flashing firmware won't fix that. Source: I have a VZW Note 8 on T-Mo. Used it with the VZW firmware and a T-Mo SIM with no issues.

Another user had SIM issues and flashed back to factory (theirs was unlocked) then changed carriers and SIM worked again...sometimes a clean flash can work...
Hi all. For me I flash all firmware at clean wipe, never any issues. I have an unlock AT&T Note 8 unlock running the latest Verizon firmware with VZW SIM active. I also have a t-mobile S8+ unlock and running the latest U1 firmware and working with Verizon SIM active. I constantly switch my firmware between tmobile, verizon and at&t to see performance and what ever else feature added.

How did you get ATT N8 to work on VZW? I flashed my Tmo to VZW and i could never get speeds above 1mpbs. Even with unlocked firmware it did not get anywhere with VZW. I heard that its because the IMEI is not in VZWs database.
Hi there. My AT&T Note 8 works great on Verizon network, it's running the latest N950U1 Firmware 2BQL2, everything works great. It will work good on T-Mobile too, lately tmobile network giving trouble, sometimes less than 1 mbps on download. Since June 2017 I been having trouble with tmobile network in my area and around, so I switch to Verizon, couldn't bother the crappie service. My location I get 215 mbps on my note 8, IPhone 8 plus 147mbps download. I prefer Tmobile but it's not working good in area anymore.

@Mr. Orange 645
I currently have a Verizon Note 8 with a TMO SIM and I'm getting 4GLTE but a few problems. Most of the incoming calls forward to voicemail and all outgoing calls the data has to drop completely before the call can connect. Will doing the carrier switching updates listed in the link above as well as flashing T-Mobile firmware assist with this problem? The phone is on 2BQK2 currently.

Verizion note8 with tmobile sim card
This is what happened when I changed carriers from the original verizon note8, on verizon network, with verizon sim and the most recent verizon pie update, to a carriers sim, that is tmobile service. And what happens, I didn't even think was possible... I put the new carriers sim in, truconnect, booted and let the phone register the new sim and network. Checked for update.... the was one, let the phone download and update. And you know how Verizon's boot logo is... it wasn't anymore. Booted the tmobile boot logo and sounds, strange. I'm not super noob and the little bit of knowledge and experience that I do have with roms and updates across carriers usually require physically flashing the rom. Correct me if I'm mistaking. Continuing.... optimizing apps....., huh?! The update flashed the tmobile software, without effecting any personally installed apps. Though the update did remove all the verzion software/bloatware, without permissions, and installed tmobile apps. 2 that are meant for user usage. They are tmobiles device unlock and the tmobile app. Which I might add, do not function, I surmise, because in not on the actual main tmobile network, but a scabbed on. I have never seen or experienced anything of the short. Please tell me if this is normal.? I was a bit upset. I did not give any carrier the permission to delete or install any app on my phone. But maybe things have changed since I dabbled. And If they have, maybe this might help the people that have been using Odin to get tmobile version rom while originally being a verzion phone. I dont think it's normal. Please tell me if this has happened to you.

Exynos S9 locked itself to a carrier?

Hey all,
I was given an S9 (Exynos version, unlocked, SM-960F/DS) that had TWRP installed on it, but was stuck in a boot loop. After messing with it for a while, I stuck it in a drawer and forgot about it until recently, when I pulled it out and decided to just restore it to stock. I downloaded a ROM for that specific model from this site ( https://forum.xda-developers.com/galaxy-s9/how-to/official-firmware-thread-regions-t3765015 ) and flashed it using Odin. This got the device to boot fine to the setup, but it defaulted to German, and rejected any SIM I put in it, even though the phone was originally unlocked. So my question is, now how do I remove the SIM lock again? I'm guessing I'll first have to wait the 7 days for the OEM unlock cooldown to elapse again so I can reinstall TWRP?

Then why would the phone start demanding a PUK for any SIM I insert into it after flashing, when it didn't before? The SIMs work on any other phone I try them in.

Because certain SIM unlocking services depend on you not wiping the phone in order to keep the unlock
You'll need to unlock it again using a paid service

In that case check it has not been IMEI blacklisted due to non payment of contract or reported stolen, you state in your OP it was given to you
If it is IMEI blocked there's nothing XDA can do to help you

What I meant by that was that a friend of mine handed it to me to try to fix after he messed with it in TWRP, getting it stuck bootlooping in the process. He had bought it factory unlocked. I checked the IMEI, it's clean. It's demanding PUKs for any SIM I put in it, even though those SIMs work in other phones; I tried a Ting SIM and a Cricket SIM.

Well the only thing I can think is to flash a stock firmware for the region you are in, pick a carrier firmware to force the CSC change, Multi-CSC that contains Germany will default back to that if that is what the phone's original CSC was, but I doubt CSC is causing this
O2U CSC (United Kingdom) for G960F is a single CSC, flash it using CSC and not HOME_CSC along with the other 3 sections
But it seems to me this was not originally a factory unlocked handset, it was unlocked by an unlocking service and sold as one
If that doesn't work, pay for an unlocking service

Is there a way I can find out what carrier the phone thinks it's locked to, or would I just have to get SIM cards from around the world and try them?
Can I do this without enabling OEM Unlock (so without letting the phone run for 7 days)?

Samsung Phone INFO will tell you the current CSC, but if it defaulted to German either you flashed a German firmware or that is the default CSC
OEM unlock is only needed for custom
Flashing a Multi-CSC ROM such as BTU for United Kingdom will have the greatest chance of it defaulting to it's original CSC
I used that app, and it indeed says the phone's CSC is German, Deutsche Telekom from what I could tell. I tried flashing a number of different FW packages (including the UK and Singapore ones) but it still defaulted to German each time.
I tried going to their unlock page and entering the IMEI, but they have no record of it being sold by them.

Like I said, try flashing a carrier branded firmware like O2U, it cannot default to German if that CSC is not included
Flash using CSC and not HOME_CSC
Sim lock is on its own secure enclave chip, so if this was truly Sim unlocked then it isn't even possible to "relock". Either was unlocked in an unreputable way, or is IMEI blocked as mentioned before.
So I just got time to re-visit this project. I flashed O2U firmware, and it defaulted to English and shows the corresponding CSC. The phone is still locked, and I checked a bunch of IMEI blacklist checkers and each one comes back clean. At this point I accept that the phone is actually locked by a carrier, so I need to instead figure out how to get it unlocked, and to do that I need to figure out what carrier it's locked to. Like I said earlier, I tried entering the IMEI into Deutsche Telekom's unlocking page, and they have no record of them having locked that phone. So how would I go about figuring out what carrier it's locked to? If that information is on its own secure enclave chip, is there any way to read it?
Afaik german providers are forbidden by law to simlock phones for several years already. Problem must be somewhere else.
Try entering the PUK of any SIM if that's what's requested. It should be on the full size SIM, else contact your mobile network operator.

SM-N975U Att note 10+ service issues

Did you set the APN information correctly?
Also are you using the N975U1 firmware or the standard AT&T firmware?
Are you using the BYOD sim card from straight talk?
What have you done over the phone with Straight Talk as far as troubleshooting? - this one can be important. If the phone isn't working with straight talk only it maybe a configuration (apn setting) or provisioning issue.
Are you sure the device is compatible with the area or region your in?
What provider/tower (Verizon, AT&T, etc.) does straight talk have you going through?
More information on what you have done to setup the phone for straight talk, troubleshooting steps you have taken, what information straight talk may have provided (etc. etc.) will help others be able to help you. Providing little or no details makes it rather hard to offer any help.
The apn won't let me put dun in the type I sim unlocked it with a puk code and got strighttalk byop I tried flashing the U1 firmware to it wouldn't take it so I did a Verizon firmware thinking that might help and same thing with the striaght talk it doesn't wanna work i put a Verizon sim in it and it works just like it did on ATT so I'm confused as to why the straight talk sim won't work they can't figure it out on their end either
I factory reset the phone reset network settings did just about everything I could with the phone besides it being funny about the apn cuz it says apn cannot be changed on this device if you put dun in the apn type i dunno the only thing I notice is when the Verizon sim card is in the phone the network mode is set to global whereas with the striaght talk its LTE/CDMA and it won't let you change it to global

Straight Talk uses different mobile providers to offer service different areas.. They utilize Verizon, AT&T, Sprint and T-Mobile (Sprint and T-Mobile have merged recently, but Sprint towers are still active).
I have seen posts across the internet that indicate you should be using the U1 firmware on the phone.. I would make sure your converting the phone to the U1 firmware properly.
If I recall correctly (this is how I did it previously) when flashing the U1 firmware make sure your doing it without the sim card installed and using the non home_csc file. Factory data reset the phone after you successfully flash the U1 firmware and then insert the sim card after setting the phone back up (so it can apply the new sim/network settings).
I would strongly suggest you do not restore a backup during initial setup when you do this. If you restore a backup it may restore previous network settings/configurations that were for what you had previously.
If flashing U1 firmware doesn't help (and since this this is a Straight Talk specific issue) then it's more then likely on the end of Straight Talk. I would call them and make sure that your sim card is the correct one for the cell towers they have you going through and the phone you have. Using an incompatible sim card (or one that is faulty) can cause issues like this. You can also have them send you another sim card to try.
Also contact them to make sure the service is properly provisioned and activated on your phone. Double check the APN with them, and see if they have an alternative one to try. It is also possible that a service outage maybe (or issue with Straight Talk internally) in your area, so I would call them to make sure that neither are not the case here.

The Global setting doesn't really matter in this case and your phone will be set to use the towers that Straight Talk has you going through.
The only thing that I can think of that would be a problem with network mode is if your sim card from straight talk is meant for a different provider then the towers they use in your area (i.e. sim card is for AT&T but the provider they have for the area is Sprint).
the straight Talk sim works in other phones no problem a s8 and a older note im thinking att has something in the software to block other apns i dunno i unlocked it with a PUK code and flashed verizon firmware on it thinking i could get passed it but the verizon sim works 100% and the att sim works 100% too but a straighttalk sim card (verizon) towers the phone tries it shows 4g and disappears and then it shows it has service but cant call it just says emergency calls only

I would not use older phones as a means to say the sim card is good. Besides that's irrelevant to what is going on with the Note 10+

Then this means one of two things... Either you didn't get the phone unlocked or else you did not convert to another carrier (or the U1 firmware XAA region) correctly.
If your using the unlocked firmware (U1 XAA region) then you should be able to edit the APN. If not then you should be able to create one.

That sounds like either the sim card isn't good, the phone was not activated/provisioned properly in there systems (call them and double check IMEI and model information), the phone is not compatible with the service they offer in your area (I suggest using the XAA region U1 firmware in this case) or else your phone is not fully unlocked.
I would also suggest google searching or else asking them for any updated or alternative APN's to try. It maybe very likely the one you have is not suitable for the phone/area... It wouldn't be the first time I have had an issue similar to this like this.
I am opt to believe the first 3 are the most likely scenarios since the phone works on Verzion with the sim card per your indication.
Yeah and the only reason I tried the older phone is to see if the sim card is activate with the number and the phone itself pulled the apn from network when I tried to flash to U1 the phone gave me a error but it took the Verizon firmware for the 975U but its still not working do you know of a good link for the firmware your talking about so I can try that

From personal experience I would advise in the future you don't do that. When you activate the phone you should activate the one you are using and definitely do not use an older phone to activate a newer phone. I have had many problems with this in the past as provisioning for an older phone didn't always work for my newer ones..

I waited for you to give more information on the issue, but you didn't. So I am sorry, but if you don't provide the details of what is going on it makes helping you very difficult. You didn't say what error you are getting, what the firmware version(s) are of what your trying to flash and what is currently on the phone.
Here's the last piece of help I can offer now.
I can tell you that the following can be found on the forum by searching:
Links and how to obtain the firmware - Multiple threads asking the same question exist here. Also Frija, SamFirm, SamMobile are just a few examples of what can be found referenced here.
Bootloader version(s) - what will happen when you try to downgrade and what will happen (along with a important thing) when you upgrade.
Websites to find firmware - SamMobile and some others have been mentioned.
Patched Odin - In case you need the latest version it has been mentioned here already.
I can also tell you that by using Google and searching for SM-975U1 XAA on Sammobile does in fact work.

Changing CSC Code - Please Help

Can someone please tell me how to change the CSC code for a S20 Ultra 5G that is stuck on Verizon??
I have already flashed T-Mobile CSC with no luck. As well as flashed latest A12 file for "TMB" (T-Mobile) from SamMobile. And dialer codes do not work on this phone. I'm guessing its becasue I read somewhere Verizon locks the dialer for code use.
Please help as I have transitioned to T-Mobile and the system keeps installing Verizon apps that I am unable to remove AND the Service Provider still shows Verizon.
Device is SM-G988U1. Yes, its unlocked.
