I have an s-offed att branded phone on t-mobile. It's running an old ruu t-mobile. I just downloaded an update to lollipop. I can just run the update?
Possibly...
you need to check a few things... what's your phone's cid set to? (you can see this in your boot loader screen).
As a general rule, I've found that if I run t-mobile radio's I have more problems than if I run either a native AT&T or the DEV edition radio and then t-mobile firmware on-top of that radio... my phone doesn't seem to do some of the hspa bands from t-mobile...
check your cid, before you do much of anything else...
If he's running a tmo ruu, i would assume he's running super cid.
I would also have to assume that he's changed the mid to tmo?
scifan, have you considered using DFS to set your bands?

What is the mid and DFS?
I have a Verizon branded m8 and am using a t-mobile mvno
(straight talk) SIM. I am considering changing RoMs from viper one to one off if the t-mobile thread in order to solve this problem of random service disconnections. Should I switch to a different Ruu? Should I have changed the RUU when I was on stock?
I apologize if the this should be on another or is own thread.
Thanks so much!

DO NOT, repeat DO NOT try to "convert" your Verizon M8 to T-Mob (with T-Mob RUU). The partitioning (possibly hardware) is different. The T-Mob RUU won't work, and may result in a permanent radio brick.
I'm not sure what is causing the service disconnects. Does the issue occur if you only use 2G and 3G? You may consider looking at enabling the proper LTE bands used by T-Mobile. From what I see, the Verizon M8 supports the proper bands that T-Mob uses for 2G and 3G. However, the VZN version only supports one of the two LTE bands (Band 4) used by T-Mob (Bands 4 and 17). Enabling LTE band 17 may or may not help. The missing support for LTE Band 17 may be related to your disconnect issues, but that's just a theory.
The hitch here, is that trying to enable LTE Band 17 requires s-off, which costs $25 by sunshine app (if you are not already s-off). And its not a sure solution, so may be money wasted.
You can take a look at the following threads, on how to enable bands on the Verizon M8. But I don't personally vouch for these:

Awesome thanks. I paid the 25 dollars for s-off already to root the phone. Sunshine works like a charm.
I'll check out the links you provided. I have a feeling your theory is correct. You described how I felt the problem was but lacked the knowledge to produce words to describe. Thanks again.
I don't know whether this is the right thread to ask this question but if you do know kindly advise me; i recently bought a T-mobile M8 which was imported from USA and had sim unlocked but i don't know other details except that its not rooted (that i checked with supersu). May be it was imported as scrap since it's an old model and may be it was unlocked from t-mobile, i just have no idea. Now the phone is asking me for a few updates which describe to tell me that these are intended to prepare phone for marshmallow update (currently it's on jellybean). Should i allow update to progress or not? i don't want to loose sim unlock.

Hello, All.
I've successfully completed my quest in getting my Verizon Galaxy S7 to work with AT&T's primary LTE band; Band 17.
At first I was using the PE1 firmware with root. I first used Phone INFO (for Samsung) app to access the service code 2263. On PE1, only the factory Verizon-supplied bands were showing as supported. Band 12/17 were not showing in the service menu.
I took my chances and flashed the G930U firmware (found on the AT&T S7 forum of all things) and booted the phone with my AT&T SIM card. I ran LTE Discovery and achieved profit. Band 17 was working with the same signal as the iPhone 6S the SIM card came out of.
Also, the 930U firmware completely debrands the phone, which is perfect since I'll be using it on AT&T. After I confirmed band 17 I proceeded to root using the normal method of flashing the engboot and installing the root/SuperSU package per the root instructions. I did not use the Verizon PE1 debloater/fixes .zip files to make necessary tweaks, post root. I performed the tweaks manually (wifi fix, CPU governer: interactive, and SecurityLogAgent) .. Let me know if I'm missing anything in those regards please.
The ONLY thing I can't do now is view all the LTE bands in 2263 Service Mode. I get a "RAT Selection option: is restricted".. I want to see if all LTE bands are unlocked now. If you know of another way to see all the supported LTE bands, please let me know!
I now have exactly what I was set out to accomplish and it's great. The S7 is replacing my iPhone 6S on AT&T and I will be buying a Note 7 to replace the S7 on Verizon. If/when root is achieved on the Note 7 I will do the same and replace the Note 7 on Verizon with the iPhone 7 (I cycle my personal/business phones as a guilty pleasure if you can't tell already)

nice work, thanks for taking the plunge
Just did the same on a friend's S7 that he was trying to get on Cricket's LTE, as the VZW firmware kept him on HSPA+ at most. All I had to do was flash the AT&T firmware and bam, LTE. I forgot to check what band it was on but at least it's an additional proof of concept.
Thanks for the info!
Can u link that ROM
I haven't tried with Samsung, however, most phones with Qualcomm modems can be accessed via QXDM or similar PC software. Often the so called hacked HTC modem driver will allow QXDM to communicate with the phone.
There are XDA threads detailing how to access the appropriate LTE bands and selecting bands of choice using the above method.
AT&T and VzW both use bands 2 and 4, so you probably have all the bands that you need covered already.

The factory Verizon firmware did NOT have LTE band 12 or 17 unlocked so I was only getting HSPA+ with little spurts of band 2/4 LTE every once in a while with the AT&T SIM card in it. Flashing the 930U unlocked band 12/17 for me so I have full LTE coverage in the same spots where I only had HSPA+ before.

One thing to note also is that the G930U firmware auto detects your carrier settings and has you restart after first boot. I'm assuming it will unlock correct bands depending on the carrier SIM you use. The G930U firmware does NOT, however, like the Verizon SIM. Upon updating carrier settings with a Verizon SIM installed, the device will reboot into recovery. Every time you power on the device it will prompt you to update the carrier settings and will have you reboot again.. back into recovery. Rinse and repeat. I had to refresh the U firmware to get my band 12/17 back after putting the Verizon SIM in.

The issue I have is with the U Firmware. However, the method does not trip knox. Make a Smartswitch backup and give it a go. If it still doesn't work flash back to AT&T stock and restore from your backup.
OP: if you haven't been able to allow the RAT selection i'd suggest this.
go to Service mode main menu (either broadcast cmd 27663368378 or app like shortcut master), 2. ue setting > 1. setting > 1. protocol > 5. sim > 4. EF_RAT Free Supporting > 1. EF rat free supporting on (select even if it shows on)> now RAT Free Support.
Then business as usual.

Your call is being transmitted over LTE so the data reverts back to Hspa during the call. Mine does this but returns to LTE after I hang up.

Thanks for the explanation. So at this point what is the point of this method? Does unlocking the band lead to a stronger signal?

You unlock the band that AT&T primarily uses for LTE. Much more LTE signal throughout the nation on band 17.
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.

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.

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.

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.

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.

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

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.
Brother give me root file for note 10 plus SM-N975U android 10 version one Ul version 2.5 plz help me
Hi
I have been able to flash the unlocked non carrier specific firmware on several Verizon Samsung phones over the past few years. Through my employer, I was able to get a free Motorola One 5g UW that I want to take and use on ATT. I know it has the antennas. I can put my sim in, and it shows cricket, but it is locked through Verizon. Is it possible to flash a Motorola from one carrier specific firmware over to another like the Samsungs ? Verizon says it will unlock after 60 days, but even still, it will have Verizon bloatware on it. Thanks in advance.
It doesn't work
Radio in AT&T and VZ versions are different.
Moreover, both bootloader are dead locked and there's NO WAY to unlock
