Well apparently it has to do with the SD card I moved the apps I had there to Internal storage and has not rebooted yet
[Sprint Samsung Galaxy S8 Questions & Answers] 954wrecker:
Maybe thats the reason you got it for $650
[Sprint Samsung Galaxy S8 Questions & Answers] danny185:
Well it's a bug with moving apps to the SD card. I moved everything back to Internal and boom no more restarts
[Sprint Samsung Galaxy S8 Questions & Answers] jkao42:
Sprint and Verizon are CDMA

ATT and Tmobile are GSM

CDMA ties the phone to the network, GSM ties the sim to the network. They use different bands, so different radios.

This was the case for a very long time. Sprint and Verizon did not use sim cards because it would increase the cost and effectively be useless since they tie the phone. This made GSM almost synonymous with sim cards, which the technologies are not dependent on eachother.

To identify what was what, each phone had a slightly different model number pertaining to the respective carrier.

More recently, phones are coming out with radio capabilities for both gsm and cdma. I believe the reasoning was they could manufacture one phone to cover all their markets and not 2 phones for cdma and gsm. This can be seen on the model numbers, as there is only 1 model number for the s8, note 5, etc...

In Sprint's case, as well as Verizon, using sim cards is now the way they are going with even though they are still using cdma, and most of the flagship phones are going to be universal across all carriers, but will still require some sort of unlock from the carrier to be used. This is because when you buy from a carrier, unless you pay for it outright, the phone is still their property.

Long answer short, you will need to get the phone unlocked from the carrier somehow before you can use it on another carrier. There is no way around that unless you can physically change the imei on the phone. However, if the phone is unlocked, you can use multiple sim cards and tie to to as many carriers as you would like.

What service did you use to unlock your phone?
[Sprint Samsung Galaxy S8 Questions & Answers] Silenus21:
Thanks. After I try to order it says the only Galaxy S7 Sprint versions and lower. No mention of S8.

I tried to contact them by email but I'm open for suggestions.

Can't use this phone without unlock atm.

[Sprint Samsung Galaxy S8 Questions & Answers] steven1193:
That's odd. It shows S8 unlock is possible for T-Mobile.
[Sprint Samsung Galaxy S8 Questions & Answers] Silenus21:
By the time I talked to them they didn't have unlock for the SPRINT version. They added that option and I ordered that service 2 days ago. I'm waiting for the unlock.

[Sprint Samsung Galaxy S8 Questions & Answers] Silenus21:

Guys so unlock authority couldn't unlock my phone. They were upfront about it and gave me a refund.

So I contacted samsungsimunlock and they said they have unlocked a lot of sprint S8 phones with a new method, and gave me a link to order the unlock for $13. Seemed cheap but after I asked again and again if it really works and they said yes it does I ordered.

Then the next day after I order they send me another email saying my phone is hard locked and they require another payment of $13 to complete the order as this is a new model with more encryption or something like that.

I replied asking what it was about and they confirmed that the unlock is more expensive but they can unlock it.

I pay the $13 rest, Now we're at $26, I figured that's okay. $26 for an unlock for a carrier that's not AT&T isn't crazy.

Anyways after some hours they send me a link with a network unlock apk and a Code to enter it on the app. I did as instructed and IT DIDN'T WORK.

Have tried multiple times, removed adblock and any app that might interfere with the "unlock server" but nothing works. I even tried to use the app without code and it says phone was unlocked, so the app is FAKE I guess.

I told them at first that if this works I would give them promo on XDA but be careful if you are trying to scam me.

Just a waste of time, I'm still talking to them but I'll just go ahead and call my bank for a chargeback as this looks like a scam.

Outstanding, thanks for the tip! His description answers almost all my questions -- but I have one big one -- after unlock, does it still work on Sprint? It sounds like you're making it so it won't work on CDMA, and now only works on GSM networks. Can you confirm it still works with Sprint afterwards? I want to be able to swap between Sprint & AT&T on the fly.

Also unrelated -- I'm seeing a lot of misinformation in this thread... (I believe) SIM cards on CDMA networks was introduced because of the adoption of LTE technology. It's required for LTE which is actually a GSM technology; it is not needed for the CDMA tech that Sprint/Verizon use. That's why old flip phones still work with Sprint, but they don't have LTE capabilities.
[Sprint Samsung Galaxy S8 Questions & Answers] njdan30:
Sorry guys haven't been back on hammer unlocks is the gsm company from the one I mentioned earlier(cdma flasher) which I used.. sprint differs from Verizon with the cdma tech, Verizon you can swap sim and it'll work in another phone right away as sprint you can't. Sprint uses sim for lte which is correct but the phone itself has 3g,1x provisions in it.

SOLUTION!!!!

-------------------

Ok, after months of research and online help, I've finally unlocked my phone.

I went with this guy on eBay that Silenus21 suggested (root not required, not rooted afterwards, does not trip KNOX).

I don't want to double-post everything I said in another thread on this forum, so here is a link to the details about my experience getting it unlocked:

[Sprint Samsung Galaxy S8 Questions & Answers] Silenus21:
Great to hear man.

By the way, can you test S-health and Samsung Pay? Do they give you an error by not launching, saying your system was modified.

That's the only problem I have atm, but the guy said I could fix it by flashing a stock firmware and I wont lose my unlock.

Problem is I already configured things how I want them, don't want to flash for now and lose my settings.
[Sprint Samsung Galaxy S8 Questions & Answers] aprwx:
I don't have errors launching Samsung Pay or S-Health, both work fine.
[Sprint Samsung Galaxy S8 Questions & Answers] mweinbach:
Flash this firmware with modified ODIN.

https://www.androidfilehost.com/?fid=889764386195902212
[Sprint Samsung Galaxy S8 Questions & Answers] aprwx:
What exactly is this? What is it intended to do?

What phone is it for (model number, carrier)?

Where do you get 'modified' ODIN? Why does it have to be 'modified' and not regular ODIN?

Will this trip KNOX? Require ROOT, or end up giving ROOT when done?

Sorry for being nosey... I just want to know what I'm flashing so I don't have a $1000 brick.
[Sprint Samsung Galaxy S8 Questions & Answers] mweinbach:
If is the G950U1 firmware. The US Unlocked firmware. Modified Odin because bootloader says G950U not G950U1. Search androidfilehost for modified Odin. No tripping Knox and no root. It's a official Samsung firmware from the US Unlocked device.
[Sprint Samsung Galaxy S8 Questions & Answers] aprwx:
Thanks... so then my question is will this work just as well on the S8+ (955), or do we need a G955U1 version?
[Sprint Samsung Galaxy S8 Questions & Answers] mweinbach:
you need to download the G955U1 off of Updato or SamMobile.
[Sprint Samsung Galaxy S8 Questions & Answers] varaff:

Hi

I am trying to buy a Samsung galaxy S8 on ebay(US). Mostly are network/Carrier locked. I want to use it in India, So the question is which Carrier locked should I go for so as to get phone unlocked easily and what all information should I check with the seller , so that that phone works for me.

Waiting for detailed Information.

Thanks in advance
[Sprint Samsung Galaxy S8 Questions & Answers] aprwx:
Since you're fortunate enough to be overseas, you can get the Dual-SIM (if you want it) International version. It will have all the proper frequencies you need outside of the United States, and get the unlocked version. You want one of these models:

G955FD -- International Galaxy S8+ Dual SIM

G955F -- International Galaxy S8+ Single SIM

G950FD -- International Galaxy S8 Dual SIM

G950F -- International Galaxy S8 Single SIM

Also look for 'Unlocked'. No reason to not buy it already unlocked.
[Sprint Samsung Galaxy S8 Questions & Answers] coolpulkit:
Hi, Thanks for the prompt reply.

Unlocked are quite costly so I am willing to buy the locked one but not sure about which carrier like sprint /verizon/att/tmob.

what should be my preference and what should I ask a buyer about the phone so that I can get it unlocked without any issues.
[Sprint Samsung Galaxy S8 Questions & Answers] aprwx:
The US version of the Galaxy S8 (G950U) is the same across all carriers, no matter who it's branded by. So the only question then is getting it unlocked. In this thread we have experience with unlocking the Sprint version, and you had a guy respond who can unlock a Sprint version, so there are options there.

Also, the G950U (once unlocked) looks like it will cover all India carriers as found here:

https://www.frequencycheck.com/comp...td-lte-sm-g950u1-sm-g950w-samsung-dream/india

So get a Sprint G950U (Galaxy S8), get it unlocked, and you're all set.

The point of XDA is not to refer users to outside pay-sites, but figuring out rooting and unlocking ourselves.

By the way you've just wasted your money because the files and instructions to unlock a Boot/Sprint S8 are all on here, just gotta use that search button.

Basically you flash an Eng-Boot-Root file then send an unlock command, and finally reflash it with "U1" like you did.

Easy-peazy!!

Hi,

I have a Sprint Galaxy S8+. I was afraid the phone will be blacklisted in couple of months. Do I need to flash the unlocked rom after unlocking the phone for not to get it blacklisted. Planning to use with AT&T sim card.

Appreciate your response.
[Sprint Samsung Galaxy S8 Questions & Answers] billa:
Flashing it with the U1 firmware does not unlock or prevent it from being blocked, and by the way it's called "unlocked" incorrectly, since there's nothing unlocked or unblocked about it, it's simply "unbranded". As long as you unlock it, there's a good chance that it will remain unblocked on at least one of the major carriers like ATT or TMO, and it should always work on PagePlus Cellular (a Verizon based prepaid) even if it gets blocked on all the carriers.

Hope that helps...
[Sprint Samsung Galaxy S8 Questions & Answers] santhiratan:
Thank you Billa for valuable information.
[Sprint Samsung Galaxy S8 Questions & Answers] ChazzMatt:
I thought all the major carriers now shared/honored the same blacklist database?

XDA partner Swappa even lets you check on a phone before buying it, so you won't buy a blacklisted phone:

https://swappa.com/esn

Also see this article:

http://www.cnn.com/2012/10/31/tech/mobile/stolen-cell-phones-gahran/

They said by 2013 all the carriers would be participating...
[Sprint Samsung Galaxy S8 Questions & Answers] billa:
More or less, but there are some loopholes in the system... as I have mentioned, sometimes the blacklist doesn't propagate throughout all the carriers, thus it may still work on some. Even if it's blocked on all carriers, it turns out that the Verizon based PagePlus prepaid seems to disregard the blocked status and does allow service at least for now. The problem with Swappa checks is that it will come back blacklisted even IF ONE of the carrier has it blocked, therefore it's not a very accurate check if you want to find out for each carrier separately. There are ways to check it on a per carrier basis, but for the average user it's easier to just try all the different sim cards.

Of course all this could change any day, so please don't rely on it long-term.

[Sprint Samsung Galaxy S8 Questions & Answers] JeffATL:
I have a similar issue and also need heeeelp!!!!!

My phone is originally Verizon branded. However I did carrier switch using Canadian CSC and Factory binary (other thread)

First I did ATT and the sim worked great. Then I flashed Oreo Beta and set CSC to XAA using Carrier Switch thread.

Put ATT sim, runs some configuration stuff and then works great. Put the Sprint sim in , while phone is running, phone detects sim card change , restarts runs Sprint config stuff , registers with Sprint, works great, repeat this process , no issues. Checking phone info app

, active CSC is SPR, so even though I was on XAA it seems like Sprint sim changed that

Now the problem, a few days go by and I put the ATT sim back, the preconfiguartion no longer runs, its stuck on Sprint. ATT sim will not work for calls. I want to be able to switch back and forth between Sprint and other carriers, not on a daily basis but I still want the ability.

I have done this twice so my phone is not hard locked to Sprint because if I flash again, I can use ATT. I tried disabling autopreconfig right after flash before inserting sim but then I can't get Sprint sim to register

Side Note: For those that say Sprint does not use sims that is false in 2017. Sprint is I think the one carrier where the sim will only work in the device registered on the account with the corresponding IMEI. All Samsung s8 models are hardware same regardless of carrier capable of CDMA and GSM, this is usually configured by inserting appropriate sim

I need a way for the sim change to be detected and for the phone to restart and configure it appropriately, the Sprint configuration is preventing this ???

The cell is not rebooting into the system, it stays on the HTC logo until the battery runs out. :(

I can boot into TWRP with no problem. :good:

I downloaded from HTC the: RUU_M8_UL_M60_SENSE70_MR_BrightstarUS_WWE_6.12.1540.4.exe

But it is not working because it can't connect, I supposed it needs the system to work.

Can someone give me some guidance? :fingers-crossed:

Thanks!
[AT&T HTC One (M8)] redpoint73:
That isn't the right RUU for the AT&T version. You would need to have the US Developer's Edition, or else have s-off and change to the Dev Ed CID or SuperCID, to use the "Brightstar" RUU. If you have the AT&T version, and still on the ATT CID, you need to use an AT&T RUU. I have them listed here: https://xdaforums.com/showthread.php?t=2751432

You don't need a working system/OS to use RUU. But you will need to be in bootloader-fastboot mode (in recovery won't work), and relocked bootloader to RUU (unless s-off, in which case unlocked bootloader is okay). IF you meet all the requirements, and still having USB connection issues, you should try to re-install HTC Sync and HTC Drivers, try another USB cable, and try another USB port on the PC.

If you choose to flash a ROM in TWRP, all you need to do is get a ROM from one of the development threads:https://xdaforums.com/htc-one-m8/development

https://xdaforums.com/htc-one-m8/orig-development

Then you can copy the ROM to the phone's storage using TWRP (to browse the storage); or alternately put the ROM on SD card, using a USB card reader. Then go to "Install" in TWRP and flash the ROM. This also assumes you phone is on relatively recent firmware (Lollipop or Marshmallow is okay for the current ROMs).
