TMOBILE GALAXY S8+ to Verizon, help

I have a carrier unlocked TMOBILE S8+ , not rooted, Is it possible to flash firmware of verizon or an unlocked firmware and move my service to VERIZON? please help! thanks, do i need to root?

Why would you need to flash anything other than wanting certain carrier apps? You just said that your phone is carrier unlocked. Which means you can take it to a different carrier.

SM-G955U to SM-G955U1

I noticed after rooting that I went from firmware U to U1.
I guess my question is can I use normal Odin to flash SM-G955U1 firmware and have my phone unlocked so I can use my goole Fi sim card?

Flashing the firmware alone will not unlock the phone. You must have the carrier it is attached to unlock it first.

When you buy a Galaxy S8 Plus at a store in the usa like Best buy or other, you will get the model SM-G955U1 which is unlocked and it works will att and tmobile sim cards, i have that model and works fine with Tmobile.

You can use ODIN to flash U1 firmware for a bloatfree experience, but that WILL NOT carrier unlock your device. It has to be unlocked by the carrier. Either by calling them direct or paying for an unlock service. But if your phone is paid off, your carrier will unlock it for free.

Of course. Search the forums and carrier switching thread.

That's a half truth. You CAN purchase the U1 model at Best Buy, but only if you specifically ask for it. They also sell the carrier versions for ATT, Verizon, and I believe Sprint.
The U1 can also be purchased directly from Samsung, as well as the carrier versions.
Yes the U1 works with ALL major US carriers. I.e. Verizon, Sprint, ATT, T-Mobile, US Cellular, and all their MVNOs.

You can try my post i would like to help you

I have the U1 and flashed U firmware, and was trying to go back to U1 and Odin is being a pita about it.
Any pointers on how to get my U1 phone that thinks it's a U now, to get back to being a U1? Get a binary error when I try. I have both firmware. U oddly says it's an XAS file (phone still shows being XAA, but U1 is an XAA file, both from sammob, and both are latest updates, Dec. 1st.).

If your getting a binary error either you are 1 of 3 things. Using older firmware than on the device. You need to flash the combination file then subsequent firmware. Like u1 combo u. Or u combo u1. Or wrong odin. 3.13b

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.

Nevermind, I fixed it. I had to perform the carrier switch and flash Tmo's firmware. Running perfectly!

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.

S9 with still on contract unlocked

Hi Everyone,
I'm expecting a CDMA/GSM s9 with bad ESN from sprint. I understand i can put GSM SIM and it should work, but will i still have to unlock it? and if yes, can it be done despite th ebad ESN. I read somewhere else someone that it could be flashed with VZN firmware using samfirm and then unlocked. Any ideas? Thanks

Sprint SM-A505U Odin flash T-mobile SM-A505U1

I am thinking about buying a SM-A505U that is locked to Sprint network. Anyone know if I can just use ODIN to flash SM-A505U1 T-mobile firmware to get it to work on T-mobile? I am hearing from other people that the Sprint variant currently does not work on T-Mobile out of box and that they are paying for carrier unlock services to get it to work. While I know carrier unlock is an option, I also reads somewhere that it may be possible to flash the t-mobile firmware and that would essentially turn it into a t-mobile phone and lock it to t-mobile (Which I am Okay with). Where as a carrier unlock service would allow me to use any sim.
Anyone know if this is feasible? Is there an actual hardware difference between the SM-505U and SM-505U1? Or is it purely software?
