Hey,
I don't know if this is too device specific, but I have a Samsung Galaxy S8+ (SM-G955U). It was originally AT&T, though I got it unlocked the day I purchased it. I use it with T-Mobile now, and I never was able to update my phone since I switched. Turns out, it was because you can only do so using AT&T activated SIM cards. Literally had to get a prepaid to update it.
My questions is: Since I have an unlocked phone and use it with T-Mobile, is it possible for me to flash T-Mobile's firmware updates to my phone without consequence instead of having to get an AT&T SIM card every time to get their firmware?
I did some research, but was not able to come up with a definitive answer. It would really save me a lot of trouble if such is possible.
If not, any other way I can update without having to get through AT&T's prepaid SIMs?
Really would appreciate any help given. This has been driving me insane.
Thanks!

I called tracfone to activate a Verizon galaxy s4 I got from a friend who switched att and iphone 5. When tech support tried to activate it they said the phone was locked and I needed to have Verizon unlock the phone.
I cannot get a hold of my friend as he's on a business trip for a week. Is there a way to unlock this myself? or can I only have Verizon do this. And if I can do this myself, will I have quirky setup and need workarounds for use?
My galaxy has a verizon sim card and a 32gb data card. My phone model number is i545 if iirc.
Thanks for any advice.

To help you get started with replies quicker I'll say that it is mostly dependant on which firmware you have and also if you have root.
those two factors will allow you to know if you can use any of the unlocking apps by chainVire if they are still around. someone will point it out to you I hope. On the go, can't show you myself. Best of everything in your efforts but read around. I'm sure someone has done it before. Welcome to XDA. I seen that was your 1st Post. Awesome!
That app is for unlocking the sim card. My track phone doesn't need a sim card.
Can I maybe just remove the sim card and have it work? Or do I need the sim card for the s4 to work at all?
Idk why they told you it is locked, all Verizon phones legally have to be carrier unlocked because of their deal with the FCC.
Translated from Calligraphy
Okay, I also remember they asking for an MEID off my S4 and this one only has an IMEI number.
Will this make it not compatible? I don't want to pay to unlock this thing if it won't work with Tracfone afterwards.
Has anyone found a reliable way to sim unlock the sprint version of this phone yet? I been looking into the threads on XDA and google, doesn't seem like theres a way yet?
Also does anyone know if i'd be able to use this phone on gsm carriers in canada after unlocking?
Thanks for future replies!!
http://www.htcunlockingservice.com/htc-phone-unlock-network/CDMA-EVDO-REV-A--USA--htc-one-m9.htm.htm i found this site for cdma devices, has anyone tried this site b4?
So far none of the methods used for m7 and m8 work. Trying to gather info and see. Any old hand willing to lend some help?
I'm confused, I thought this was a global phone and thus I would be able to pop in a sim from another country and have it work automatically? Either that or be able to get an unlock code directly from sprint. Was I wrong by assuming this? : I'm going out of country in two weeks and more than likely am screwed if this is the case D:
Im not sure but I think this may work

Just tell me every details you get
Even if you did find a way to simunlock it it wouldn't do you much good as the Sprint M9 lacks the radio frequencies required to work on most other domestic carriers:
http://s4gru.com/index.php?/blog/1/...rock-out-with-their-flagships-for-the-season/
Second, the One M9 was not tested, thus is not authorized for domestic GSM/W-CDMA bands. Rabid phone unlockers under the new Sprint domestic unlocking policy, consider yourselves forewarned.

I bought an HTC One M9 that was supposed to be unbranded and unlocked and turned out to be a Sprint locked phone.
The guy who sold it to me was able to get the unlock codes.. but I am outside the US and trying to unlock the phone requests an update (i assume from the carrier).
But as I am outside of the US i have no link to the carrier..
Is there anyway to force the sim unlock so i can enter the code?
When I put in the sim, it says SIMLock enabled contact customer service.
Sim Unlock Sprint HTC One M9 outside the US?!
Trying to sim unlock the Sprint HTC One M9 variant. I've managed to unlock the bootloader and root the device but now I'm stuck with the next step. I live outside the US so Sprint cant help me and the phone hasn't been activated on Sprint. I was hoping i could sim unlock this the same way I did with my M7 but no luck? Help anyone?
Okay, I have a question. I have a Sprint HTC One M9, and I want to go to the T-Mobile store tomorrow and get a T-Mobile SIM for it. I'm not allowed to post a link to the page I'm referencing (under 10 posts), but according to Sprint's page "FAQs about Unlocking Your Sprint Device":
Under the second bold question, where it says "Will Sprint notify me when my device is eligible to be unlocked/has been unlocked?": It says all DSU-capable devices are automatically unlocked. This means that I should be able to go to T-Mobile tomorrow and get the SIM card and just put it in the phone for it to work, correct?
Sorry for the noob question. Definitely appreciate any help.

Nope it's still going to be locked. I bought my phone outright from HTC and spent hours trying to call Sprint (both regular and international support) and get it domestically unlocked, and all they give me is the run around and my MSL. They keep saying the new provider can use the MSL to reprogram the phone to make it work, which I believe is what happens when you flash to a prepaid CDMA carrier, not for GSM.
I kept arguing (with the call center manager) and went over the terms on the Sprint website to no avail. They'll unlock the SIM for international use no problem, but domestically, they will say it's impossible.
I've only heard of 1 other person from the Sprint forums getting the DSU unlock on the M9 and it was a pain for him as well. I pretty much gave up. Not worth the hassle. If you get yours domestically unlocked, please let me know and I may try again.

as I know this is international unlock. so when you will arrive to your country you will need just local sim card and it will work well if the phone was unlocked correctly before
So I learned the hard way that you can't have it all.
I travel for work quite a bit and I was in the Middle East working when my Verizon S7 Edge started to have problems. I looked for a replacement in Dubai and was happy to find the S9+ at a reasonable price and with the 256GB option (which I wasn't finding in the US). I popped in my Verizon sim and life was good.
Then I returned to the US and. nothing. worked. I had forgotten that Verizon was strictly CDMA in the US and this phone had no CDMA radio.
I also was noticing that the samsung pay app was locked to the UAE version which was annoying but not a huge issue...I couldn't add American Express credit card which may or may not have been due to that region setting.
So in order to actually get service I switched to T-Mobile and have had decent data rates. However the phone doesn't use volte or wifi calling which is very bad since where I am staying is somewhat of a dead spot for mobile coverage. I basically can't receive phone calls here and making a call requires me to wait about a minute for the phone to figure out what protocol to connect to (dowleveling to either a 3g or H to actually connect and dial).
My initial research tells me that I don't want to root the phone and lose all ability to use samsung pay, but I would love to do as much as I can to the phone to get it working as best as possible.
Can someone chime in here to let me know what's possible? I don't want to experiment too much, and it's been rare over the years for me to keep up with all the root/firmware/rom etc. that has become available. My last real era of rooting phones was many years ago with iPhone and even then it was a lot to keep up with.
thanks in advance!
bump.
Anyone?
I had the same issue. I ended up rooting to get TMobile volte/wifi-calling. Also, by rooting you can also use Verizon Wireless; however, only with LTE.
You could use Google Pay lol.
Furthermore, I suck at giving reasons, but that's what I did.
Don't quote me on this, but from what I understand, you can use the patched ODIN and flash the firmware's CSC outside of it's region and change it to XAA. There is also a guide to changing CSC without root that may work as well.
From what I understand, the G965F is unable to load the XAA csc without root since it is only for the Snapdragon version
I ended up using Tekhd's tmobile detonator after I bricked my G965F/DS atleast 3 times. It works great now.
The way to change csc without root is via a combination rom and using Realterm. Using TMB CSC on a global G965F/DS ROM will end up in a PUK code lock. I tried ALL the US CSC on my G965F to confirm this.
Hi,
I would like to buy a V60 and use it in Europe.
But reading about it makes me wonder if it is such a good idea to buy this phone.
Could you help me out, I'm a bit of a newbie to Roms, rooting and fixing phones so they work.
I was reading something general about importing a unlocked carrier phone and it stated that I can buy an unlocked T-mobile or other carrier and use an european sim. There it stated that it will come a time when you need the us carrier sim card to perform things and I will be unable to do those things without the correct sim card. I do not remember what those things where. Perhaps it was If I need to update it. Is it true that you have to have the carriers sim card even if it is unlocked?
Is there any other problems one might face. e.g.
This was the latest LG phone so perhaps they will not care about customer service so much:
perhaps LG will stop posting security updates:
From what I understand there are two parts of the software of a phone: the firmware and android. The firmware is LG specific and I will not be able to get updates on that. But for android which is on top of the firmware there should be a way to get updates even if LG stops posting them, or?
If not, can I switch to an other rom to have them?
Can I update to a later android version even if LG does not post one for the phone?
Can I root the phone and be rid of all the us carrier stuff, get a phone that is not associated with any carrier?
yes you can root the phone and flash EA firmware. instructions available here and works perfect for ATT unlocked phones. also you can buy a Verizon version, use it 60 days in the Verizon network, after it will work anywhere and get updates. the problem is that no new LG V60 devices left in the stores.
So I have an issue with my current tablet that is locked to T-Mobile not getting any data using a normal phone sim. I'm not about to risk buying a different T-Mobile locked tablet or even one with T-Mobile Firmware as I have a feeling I will run into the same issue, and I can't get any clear answers about it.
Does it make sense for me to buy an ATT Unlocked S7 and use a T-Mobile Phone SIM in it then? Surely an unlocked Tablet from another carrier wouldn't get caught in the data-only SIM mess right? Or are there other ways around this issue? Ironically all I really need is data, but I need to be able to use a normal phone sim from my T-Mobile plan.
Usually t-mobile doesn't care if you use tablet plan sim cards inside phones but it does limit the usage of phone plan sim cards inside tablets.
So with tablet from popular/well known brands, no matter if it's from another carrier or a factory unlocked version, you are almost certain to be detected by t-mobile and it will either block the tablet or limit the speed to 3g speed, especially with those free phone lines with unlimited data.
You would better go with an imported tablet not dedicated for US market.
