Switch Firmware,

Hello, xda_developers.
I just got mail S7 Unlocked in the mail that I ordered from eBay, I believe it was a sweet deal CAD $549.99 + tax. I am with Telus BTW. Let's get to the point.
The phone is with Sprint which has bloatware and APN is locked out. I want to flash a new firmware onto the phone without Tripping the Knox. I looked into the 930U Firmware but don't know which one to pick. I looked into the thread: "Bloat free firmware 930U....anyone tried it?" and saw the part about root, so I backed out.
After I looked into the Sprint SM-G930P firmware and saw few different "Regions": SPR, XAS, and VMU. I found"SPR" is Sprint, and "VMU" is Virgin Mobile USA. For "XAS" I am not too sure, but "XAS image has the APN section unlocked". ("Here" )
Afterwards, I found the forum "Found a code...interesting...." and used the code "##BRAND#" and removed the Sprint boot logo, and some bloatware but the APN was still locked out, and still had "Hands-Free Activation".
I need help picking the right Firmware for my phone, which will let me add APN, and remove the "Hands-Free Activation". I do not want or need to root the phone.
The phone is up to the latest update:
Software Version: SG930PVPS2APG1 ,
Hardware version: REV0.6 ,
Baseband version: G930PVPS2APG1 ,
Build number: MMB29M.G930PVPS2APG1 .
I did not want to flash firmware without knowing for sure it will not brick the phone, brand new phone in a long time, I don't want to break it or brick it on the first day.
Aswell, I am not sure if I can flash a Canadian firmware, SM-G930W8 or the Global Firmware, SM-G930F.
Thank you for reading, hope you can help me out.

The 930U firmware will work perfectly fine without root. No bloatware and you can modify the APN's.

the 930U firmware is bloatware free, and I don't have to root the phone? Also does it have the "Hands-Free Activation" or the "Activate this device" in Settings?

It's bloatware free and it doesn't require root. And when I flashed...it simply activated my device and there's no activate device in settings.

alright, thank you very much.
Going to go flash it now
edit: Quick Update, went to flash the G930U files(firmware?) and it all went smoothly. Takes time to register onto network. any fix without root?
edit 2: Just did a factory reset from recovery, seems to have fixed the slow network register
edit 3: The phone seems to run warmer than the sprint firmware, no idea why

Never mind, I am, an idiot.

Congrats on the phone! That is a good deal considering the phone goes for 899 brand new, and I'd assume around 600-750. But with black listing these days I wouldn't trust Kijiji etc.
Your phone should work fine except for LTE. Its missing I believe 2-3 bands for LTE but on the plus side it's the bands that bell/Telus don't really use much like 2600. So if you ever see soneone else have LTE and not you that would be why but, then again the bands you don't have usually are for rural areas

Thank you very much. It's a pretty nice deal, still going on I believe. I don't have to worry about the blacklist. Even without the 2600 band data works great, really don't mind not having a few LTE bands, for the price i got the phone for. With the 930U firmware, it works great.

The U firmware has more/better LTE bands enabled than the Sprint (P) firmware. I strongly doubt it's missing any LTE bands used in Canada.

I believe your correct with the U firmware It shouldn't be missing a band or 2 like it is on the Sprint firmware. But yes about the same price as you'd get it on Kijiji (since there's tax) but it's new and don't have to worry about the blacklist

FWIW - here are the bands that are apparently supported in the 930U firmware. This is band priority list from the LTE section of the ##DATA# menu. Not sure which bands Canada uses, but it looks like the only major one missing might be band 17?

I think the Canadian networks may have started using MFBI on band 12 (like AT&T has). If so then B17 would no longer be necessary in Canada. The best place to verify this might be to post a question about it on the Bell and Rogers forums on Howardforums.

In G930UUEU2APEH thread it is said:
"root with the only g930a method there is right now"
So, this universal firmware can be rooted, right?

Can any one give me the link for downloading the 930U rom for my sprint sm-g930p and are they facing any problem with the same

Did the actual flash fail, or did one or more of the MD5 checks fail? What version of Odin did you use? If any of the MD5 checks failed, you just need to download the firmware again - your download was corrupted. If the actual flash failed, the most common cause is the USB cable/connection. Try another USB cable, and/or another USB port on your computer, and don't move the phone or computer around while it's flashing. Odin is very temperamental if the connection is not perfect.

I'm confused too. Are you wanting to use it on Sprint or T-Mobile? Do you have a sprint account, and did your phone activate on Sprint? I don't have any experience using a non-Sprint sim with this phone/firmware. The only thing I can suggest it maybe do a factory reset and go through the setup/activation with the T-Mobile sim already in the phone. Good luck.
If you're wanting to use both Sprint and T-Mobile on this phone, I'm not sure if that's possible. From what I've read elsewhere, even though this firmware is unlocked, it can only be active on one carrier at a time. I don't think you can switch back and forth at will, without activating/deactivating from one carrier to the other. I could be wrong though, as I have not used anything but my original Sprint sim.

is there a How to on Canadian Carrier Switching?

I've looked all over the forums and all the threads on carrier switching refer to switching US S8 variants to US carriers.
Can someone please explain or point me to a thread that explains how to carrier switch Canadian providers that would be fantastic. In particular I want to go from Rogers to Freedom Mobile (aka wind mobile) . My phone has been factory unlocked.

I can tell you from experience that freedom does not have any carrier specific features, so doing a firmware switch wont benefit you in any way I dont think.
You can however go onto sammobile and download the firmware for freedom and flash it using Odin. Again probably no real benefits. You would benefit if you were going the other way tho, as Rogers, Bell and Telus have carrier specific settings in their firmwares.
But since you are carrier unlocked, you could try a factory reset then put your freedom sim in it and boot up. It might install the freedom files. My S7 worked this way when i went from a Bell locked phone to a Koodo sim...
Edit: That link has an unlocked canadian firmware as well, you could use that firmware too.

Open the dialer and type *#243203855# then select GLW, this will change your csc to wind mobile/freedom, it'll wipe your phone..

Hi Peachpuff. I have an unlocked S8 phone from a Bestbuy canada marketplace seller. I tried using your code to change to the Telus CSC so I can get VOLTE but got the invalid MMI code error message. The about phone says its an SM-G950FD, and the only code the phone appears to accept is the one displaying the EMEI.
Hope you have some guidance on that ?
Thanks

That's not a canadian s8, its an international one, so that code won't work and i doubt you'll get volte working at all.

The "U" model is the newer model that Samsung introduced on June 30 of 2016. It is UNLOCKED for North American carriers. It will run all of the big 4 (AT&T, Sprint, Verizon, & T-Mo) based on which carrier's sim card you put in it. Samsung introduced similar to some of the Motorola models or the Nexus/Pixel models that can be taken from carrier to carrier. That is ONLY true of the 935U. If it does not say U, it is not the North American unlocked model. It was sold directly from Samsung, Best Buy, and other online electronics resellers. None of the four US carriers sold this model since they sold their own model. Because it is not carrier locked, there is very little bloatware. Now having said all that, the bootloader for the "U" version is absolutely locked by Samsung so it cannot be rooted or flashed at this point. That is everything I know at this point. Good luck. The product is reaching end of life, so you should pick one up soon if you want, but you can take it to any carrier in the US.

So you are asking about 935U software running on 935A hardware? That doesn't seem to be what the original post says. Everything I told you was about 935U hardware only. In reviewing your original post, it seems you are asking a hardware question. Nevertheless I wish you all the best with whatever device you have. Good luck.

If the motherboard says 935A, you have the AT&T version that was flashed with the unlocked U firmware. The U firmware can be flashed on any of the US carrier versions. Flashing the U firmware removes the carrier bloatware but it won't unlock the phone. If the phone was fully paid for and not blacklisted as lost or stolen, AT&T should unlock it, otherwise a 3rd party unlock service should be able to provided it's not blacklisted and you tell them it's a 935A, not a 935U.

Hi all. its probably T-MOBILE G935, then check out IMEIFIX.com, if not then Sprint G935P check out IMEIGURUS.

I think it might be a mix + carrier needs to support and device needs to be whitelisted in their system. Which model do you have or planning to buy?
XAA will contain most US carrier's CSC codes, so this what US unlocked model comes with.
TMB is for T-Mobile, which is the same as sold by T-Mobile.

If you put T-Mobile sim card, then go to phone app and access the settings and then check if you see WiFi Calling there. To find out what you CSC is, just download Phone INFO app(Samsung) from play store. The launch the app and swipe to the left to go to CSC section.

USA(XAA) is an unlocked version that works with US carriers.

Right, I had that question myself before, but you have to make sure which model you have and what is the CSC of your phone. Carrier versions should be: G950U, but US unlocked is: G950U1. There is a little difference in XAA and others, but if you really want unlocked that would have CSC codes of most US carriers, then use XAA image. It will allow you to put any US sim card in the phone and it should work.

I would suggest checking out the carrier switching threads here. There are several... One here and at least one other I think in the T-Mobile S8 guides forums section, that walk you through changing the firmware to the US unlocked while keeping carrier features.

You will need to download the USA(XAA) firmware. That will give you the unbloated version and you will have WiFi calling and volte with T-Mobile. Just type in sm-g930u1 and select the XAA firmware. I have full T-Mobile capabilities with that firmware which is the US Unlocked model.
Make sure to use the regular csc file and NOT the home csc file.

Unlockboot expensive, but do you recommend?

Hi,
I found that "unlockboot" can help me to unlock my S10+ SMG-G975U, that previusly UnlockUnit identify my device as Unavailable - CDMA and something like that topic.
Do you recommend unlockboot to unlock by 99USD?
Thank in advance!

Are you wanting to carrier unlock it or bootloader unlock it? The phone is already carrier unlocked, just insert your SIM. The bootloader cannot be unlocked on the G975U.

Hi,
No, there is a message that said "Sorry, your device can´t be activated on another carrier's..."

What carrier are you on? If you flash the U1 unlocked firmware and insert a SIM, it should work. If you don't want to flash then it looks like you need an unlock code, which is odd because from what I have read the G975U is already carrier unlocked.

If you purchased a carrier branded model new it doesn't normally come unlocked. You need to own the phone outright before a carrier will unlock it and some carriers require that the phone be used on their network for a minimum period of time (usually 1 or 2 months) even if you did purchase it outright from them.
You cannot flash U1 firmware on an S10+ unless it's carrier unlocked.

Hello,
I flashed this one: https://forum.xda-developers.com/s10-plus/how-to/sm-g975u-firmware-downloads-tmo-spr-att-t3908657. Everything goes ok, and the message of unlocking appears, requesting me the unlock code.
Any suggestion?
Thank you!

Actually you can flash U1 firmware anyway, but it will still be locked to the same carrier without the unlock code. Carrier locking is IMEI based, not software or device based.

Have you tried calling the carrier and asking them to unlock it? Most carriers will unlock your phone once you've had it for 3 months.

Recently the firmware for the S10+ became all-inclusive like on the S9 models so I'm not sure if flashing U1 firmware over carrier firmware will get rid of the carrier apps anymore. They seem to get installed now automatically as part of the provisioning for the installed SIM card. If you have a network unlocked Verizon phone and insert a T-mobile SIM you end up with the T-mobile boot animation and T-mobile apps and all the Verizon stuff is gone. Maybe the U1 firmware doesn't work the same way.

I read in a different thread that you have to activate the phone with Verizon and wait 3 days. After that just put in another carrier SIM and the phone should auto unlock.

this is incomplete and some is inaccurate..
his vzw device doesnt need to be paid off but does need to wait 60 days from activating on the verizon network before they unlock it..
also you can absolutely flash u1 firmware on a u device, it has literally nothing to do with the sim lock.. and no, flashing u1 on u doesnt magically unlock the sim..
pretty sure on U firmware vzw device will say message cannot be used on another carrier yet.. on u1 will i believe prompt for unlock code when a dif. carrier sim is inserted

sprint however needs to be fully paid off and active at least 50 days and account needs to be in good standing to be eligible for sim unlock

Hi,
I found that "unlockboot" can help me to unlock my S10+ SMG-G975U, that previusly UnlockUnit identify my device as Unavailable - CDMA and something like that topic.
Do you recommend unlockboot to unlock by 99USD?
Thank in advance!

are you trying to unlock the Sim or the bootloader? i have the same phone and was disappointed to find out i couldn't unlock my bootloader. no root no custom rom smh. but it's because Samsung removed the developer option to "oem unlock" which must be enabled to unlock. so done online service claiming to be able to do so is crap and waste of money. also if you're trying to unlock the Sim which I think that's what the site is claiming to be able to do because Sprint is a CDMA network if you unlock the SIM the only other service you can put it onto would be boost or Virgin Mobile which just use Sprint's towers. they're the only network still using CDMA. so pointless all the way around sorry buddy.

Thanks for your reply!
I am trying to unlock the sim, the cellphone was Verizon US, (refurbished by asurion). And wanted to use Movistar (Telefonica, from Mexico just GSM). I am searching to do a root and try to follow this guide: https://forum.xda-developers.com/showthread.php?t=1693491. So what I understand, the site "Unlockboot" could do a CDMA unlock, and after 3 days of chatting with the person that is on service there, sounds that are possible, also is possible that I can continue using my GSM provider of Mexico. But it is very expensive 99$ USD is 2000$ MXN... Also, I do not trust a web service, also if there isn't a reference on this forum.
So that's the update...

I think ibowtoandroid who maintains multiple Samsung device threads on XDA has an unlock service but I'm not sure what he charges.

Where I live there are multiple independent phone shops that sell SIM cards and phones and are not affiliated with a single carrier and also phone repair shops that offer to SIM unlock a phone as a walk in service. You can probably find a shop to do it if you don't trust an online service.
