In need of a lil guidance?

Ok so I need some advice. I was finally able to root my Galaxy S6 recently with Odin/CF-AutoRoot. Now i've got a few questions before I go any farther. The main reason I wanted to root my phone was in hopes to edit my APN's and get my data working. This galaxy is on Marshmallow, the Sprint/Boost Mobile model. I bought it off ebay, when i first got it I took it to AT&T to get service on it. They got my talk/text working but not data because there was no APN options under Settings/mobile networks/etc. That option was not there. I'm hoping if I flash a rom that will restore my missing APN options.
-I need someone to recommend me a rom. I'm looking for a stable rom, preferable debloated too. I just want the phone to function as it normally should and have the apn options back.
-Also, do I need to install a custom kernal too?

This is the forum for Sprint Galaxy S6. Did you buy the Sprint model or the AT&T model.
From what I understand, they are different.
Sprint is on CDMA network and AT&T is GSM, and the two are not compatible.

It sounds to me like you want to use the Sprint S6 on AT&Ts network. Should be possible. However, I believe it needs to be unlocked first in order to use the GSM bands. This may be one of the issues.
Secondly, I recommend doing everything yourself as there aren't many ROMs available for the Sprint S6, so tweaking everything is something you personally will have to do to make it work on AT&T.
Thirdly, why did you get a Sprint model if you wanted to use it on AT&T? I recommend talking to sprint to help you. Custom kernel has nothing to do with carriers, so using the one you have now will be fine.
IMHO: You should have done your research first. Honestly if you wanted to use it strictly for AT&T then you should have bought an AT&T variant, all your headaches and issues wouldn't exist lol. That being said, what you want is 100% feasible, but not by the average Joe. It requires some tinkering and know how and knowing how to navigate around the device.

Just an FYI: You are right, but you're not fully right. lol
Sprint and Verizon CDMA phones normally have GSM capabilities for overseas business travel. In order to unlock the GSM bands, you must get the device unlocked, or tell and pay sprint that you are using it overseas. International Unlocking allows for overseas use, Domestic unlocking allows for USA GSM Carrier use. My phone is International and Domestically unlocked thanks to a very kind and generous xda member.
However, a GSM phone will not work on CDMA networks, just cause they lack the hardware. There really isn't a niche for it so they don't make them.

This seems to be the root for S8+

Has anyone here tried the new root file for Verizon S8+
https://download.chainfire.eu/1080/...to-Root-dream2qltesq-dream2qltesq-smg955u.zip

It will only work with an unlocked bootloader. Since all US Snapdragon based S8's have a locked bootloader it useless.

So why has Chainfire made this at all if it does not work or will brick your phone? I should ask him but not sure he will answer.

He clearly states that it only works with an unlocked bootloader. If the snapdragon versions of the S8/S8+ had an unlocked bootloader it would work. Not sure why you could have an issue with him.

The U version isn't ever unlocked. Not with him. I'm just confused why it seems this would work on that model but it doesn't

If the bootloader ever gets unlocked by any means, it will work.

You missed my point and question to him. Which is "U" model is LOCKED because it is all phones inside the USA that are distributed by all 4 major carriers. So there is no such thing as SM-G955U which is unlocked. Does not exist. Thus I wanna know why there is even a zip file which chainfire created since it cannot be used on any of these phones. And why would it "get unlocked"....it is done at the factory. Only way to "unlock" it is to use a root method like was done on S7, where it basically involves flashing an engineering boot image/kernel that has root. At some point, this probably will be made and then using same modified ODIN (PrinceComsy) would potentially be the solution.

I will try and clear up some confusion. All US snapdragon versions of the S8+ have the same model number SM-G955U. There is an "unlocked" SM-G955U version of the S8+ in the US. It is carrier unlocked not bootloader unlocked. Apparently the CSC file carries the carrier information in the firmware. Also the S7 was rooted but never bootloader unlocked. So you could use most root apps but you could not modify any system files. The root was achieved with an engineering kernel and was not very useful.(ie bad battery life, phone getting hot and unstable). You could however flash any US S7 to any carrier or even the Unlocked firmware.

But if you cannot flash even the csc, how do you gain root access when Odin basically does nothing. That's my question and point. Seems that if I stick with Galaxy phones that I'm never going to attain root again. Probably because they don't want risks of pay apps being misused. I have one app that refuses to even run if I have usb debugging on. Vendors are getting smarter about locking things down.

It's not Samsung's fault...it is Verizon, AT&T, Sprint and T-Mobile. I can't even take my Verizon phone and change it to T-Mobile. That's ridiculous!

If LG lets it's consumers unlock there bootloader then why don't samsung? I'm selling my ccarrier unlocked s8+ and buying a unlocked g6. Screw this crap. I hope samsung goes bankrupt! SAMSUNG ALLOW US TO UNLOCK OUR BOOTLOADERS.
I wish my S8+ was rooted?

The reason you can't do this is the bands are different (I believe). Or, at least Verizon is CDMA while T-Mobile is GSM. I don't know much about the differences between CDMA & GSM, but I know that CDMA phones won't work on GSM networks & vice versa. That's why Verizon phones won't work on T-Mobile. Hopefully that (kinda) cleared it up for you.

My goodness you could not be any more wrong..... That is no longer the case anymore. Verizon phones work on T-Mobile and all GSM carriers. I should know since I was with Verizon and I switched a while back but am now back on Verizon. Some phones from T-mobile won't work with Verizon but some do. It just depends on the phone and what bands it has. Like the S8 from T-Mobile will work on Verizon but an iPhone 7 from T-Mobile won't because it doesn't have CDMA bands. It's simple research

CDMA is only for 3G. With 4G, Verizon is using LTE GSM (same with AT&T, T-Mobile).
Verizon LTE covers over 98% of their network, but there are still some remote places where there is only CDMA coverage.
Verizon is moving away from CDMA and it will be retired by 2018.
So as long as you don't mind not having CDMA in a few places, any LTE GSM phone with Band 13 would work with Verizon.
Look at HTC U11, it doesn't have CDMA, but it's still advertised as "Verizon certified".
Sadly, the Internationals versions of S8/S8+ don't have band 13. But fortunately, all US versions have both bands 13 and CDMA support. That's why you can switch to any carrier as long as it's a US version.

My point exactly about the S8's. US variants are all the same no matter what carrier. All Google phones after the Nexus 6 are the same way. The Nexus 6 worked on all US carriers no matter where you got it from and it's like that all the way to the new Pixel phones. Where as iPhone's, just as an example, have different bands when it comes to different carriers. Unlocked, Verizon, and Sprint iPhone's have all bands both CDMA and GSM where as the GSM ones like those bought straight from T-Mobile or AT&T only have the GSM bands.

You're NOT stupid! I had no idea either. I know that I tried to switch my Verizon S8+ to T-Mobile but it wouldn't recognize my IMEI so I just figured the two networks were different

I have a unlocked verizon(xfinity mobile) s8plus on tmobile right now.. The phone had no issues on setup to go on the tmobile network..

SIM unlocked T-Mobile Z2 Force - on Verizon?

There are a ton of entries on XDA about sim unlocking the T-Mobile and Sprint versions of the Z2 force, but none of them confirm once unlocked if they've used it on Verizon.
T-Mobile's page confirms their version utilizes bands 2,4 and 13 - all of which are Verizon's LTE bands.
Can anyone confirm?
I'm looking to buy this to replace a work phone on Verizon. My personal account is with T-Mobile, so would be very nice if I could just flip sims whenever I'd like. Appreciate in advance the responses!

(unlock T-Mobile bootloader, sim unlock, root and put a custom rom with safety net passes)
then type this on google and try.

Oh if this works I would be so happy to switch back to VZW. Anyone attempted it yet?

I'm interested in knowing if anyone tried this too

I’m too chicken to mess with anything not official from xda on my daily driver. I’m sucking it up and waiting out the period for the device unlock app to ‘officially’ sim unlock and try. When that day comes, I’ll post here.
I think it’s ignorant having to wait for a sim unlock for a phone you bought outright.

Eagerly awaiting news on this - why is there a waiting period on the sim unlock? How longs is that period? I'm about to head out to Tmobile store and buy me one too.

Verizon's LTE band 13 is exclusive to the Verizon model unfortunately. I wish it wasn't so you could use a bootloader unlocked Sprint or T-Mobile edition on Verizon. I did that with the Google Pixel - used the universal one on Verizon. I just got used to having an unrooted phone with the z2 Force. I switched to blokada after many years of always using ad away. I think most all ad blockers on unrooted phones are VPN based so it lags WiFi and mobile data a little but that's what you get to work with if you want the best moto phone running on Verizon.

Could you provide your source of information on that? T-Mobile's listing of the Z2 Force lists band 13 LTE capability, and multiple sources say that the Sprint variant has band 13 too. I am just about to pull the trigger on a Z2 Force variant that is bootloader unlockable, but whichever carrier version I get has to work with Straight Talk Verizon.

I'm seeing the sprint one listed as having band 13 now everywhere actually. My bad. I don't recall seeing that back when i got it and was shopping around. Let me know if the Sprint one works for you on vz because i miss having a a rooted phone.

The only different thing on the US phone's is the oem partition. Everything else hardware and software are very similar to the point I want to say identical. (Obviously, some slight changes in /system and stuff but that's with the territory of using OEM ROMs). I have flashed a T-Mobile flashall and it worked. I flashed back to Sprint shortly after. I did it for science.

So in short, will am unlocked T-mobile Moto Z2 work on the Verizon network with a sim swap? Or does it require a root or the bootloader thing that was mentioned, I haven't done either one as I am content with factory.

So, what's the verdict? Will unlocked T-Mobile Z2 force work with Verizon?

Most likely will not work. T-Mobile variant is GSM and most likely doesn't have the CDMA bands on it or programmed into it. Only thing you can try is flash Verizon firmware and see if it works. 99% chance T-mobile firmware will not work, Verizon firmware has about a 40% chance of working. If you don't have the device, I'd suggest not investing as no one has tried it.

I tried the Verizon flash all on my TMobile z2. Didn't work.lost baseband.
The flash all looked as if everything flashed properly...but when it finished and rebooted it still had tmo splash screen. So I don't know if it really did it.
If it's worth any thing my Verizon Sim in my tmo z2 gets great data...just no calls/messages

I have an unlocked Sprint variant that I flashed to Verizon and use with Straight talk Verizon. The only issue is that so far whenever an update comes in I have to back up all the things I want to save and flash the updated flashall, because the automatic updater just keeps on failing. I don't know if this matters, but I'm bootloader unlocked (had to for sim unlock) but without TWRP or root. It's possible that if I would try relocking the bootloader that the automatic update process would work. I briefly had a Mint sim in there (T-mobile) and everything seemed to work. I didn't really try things out with the Sprint rom, but as I remember everything worked, I just didn't like the icon style plus always having a notification saying something about a non Sprint sim card

Was it officially unlocked or was a modified file flashed to your phone? If you had a third party service unlock, then the hash check for that partition is incorrect and that's why updates fail.

I had a third party unlock it. Actually, it was the guy that people on this forum have talked about.

Will this work on Verizon? My tmo z2 was unlocked by TMobile not a third party

No it doesn't work... You can get data but that's it..

Hi- I am wondering about being able to buy a new-in-the-box z2 Force that was originally sold for Sprint, and being able to flash the T-mobile firmware to it for use with them. Is this possible? I have done this for Galaxy S8/S9 phones, but there is a deal right now where I can get this phone with 2 of the mods for dirt cheap, but it won't really matter if I can't do the conversion. Any advice?

Buying from Samsung instead of carrier

Hey, I plan to buy my Galaxy so from Samsung rather than my carrier (ATT). I have a couple questions. Will I just be able to add the Sim currently in my Galaxy say or will I need a new one? Also, will I have to take it into the store?

Just put your existing soon card in and away you go. No need for anything else. It's what I did when I got my Note 8 from Samsung.

If you buy it from Samsung, the phone it's unlocked, so you can use any valid SIM (including the one you are currently using now).

Samsung has an unlocked model available on their website along with carrier specific models. I would think the carrier specific models are the same as the phones you would get at a AT&T or Verizon store. Correct me if I'm wrong.

I'd like to know this as I would like an unlocked bootloader but.... I would like the Carrier version for some additional features like VoLTE/VoWifi.
Right now I'm torn between just going to Best Buy (since in the states) or just getting it directly from Samsung.

The carrier versions will have the standard carrier bloat pre-installed.

I can't find the exact band specifications of each of the models... Does anyone know if the hardware/antenna chips will be the same on T-Mobile vs. unlocked from Samsung? I am assuming there are certain bands missing from the unlocked version if you plan on using T-mobile's network, but I can't confirm this....

Best Buy's doing a $100 off if you preorder on Friday just heads up.

It looks like the answer to our question is on this page: https://www.techwalls.com/samsung-galaxy-s9-sm-g960-g965-model-number-differences/
The T-Mobile version seems to be missing the following, in comparison to the unlocked US version:
4G FDD LTE B71 (600 mhz) - This is T-Mobile's new spectrum... this seems important to have (just google t-mobile 600mhz)
2G CDMA and 3G CDMA - I don't believe this matters to us
3G TD-SCDMA B34 and B39 (2010 and 1880mhz) - I assume these will be missed if outside LTE coverage?
But in general, the unlocked version seems to support more bands than the Tmo version
So, it seems if one is on the T-Mobile network and plans to stay there, they really should get the T-Mobile version of the phone.... someone please correct me if I'm wrong.

I'm with AT&T and I'm pretty sure there will be no wifi calling on any phone other than the AT&T version. That's a feature I want. If it doesn't matter to you an unlocked phone may be for you. I don't know for a fact that wifi calling won't work on an unlocked S9 but if it does, it will be the first. I don't want the extra carrier apps but they aren't going to cause me any grief on a beast like this phone. I'd rather have the services the carrier provides if I'm going to use them. If It turns out that wifi calling works on the unlocked S9, I may revise my plan but I doubt that will happen. I'm pretty much done with the rooting/modding stuff so that isn't an issue. Even the master hackers are going with stock phones d/t the features and security.

Unlocked vs Tmobile/Flashing Carrier

I'm curious as to what doesn't work when you purchase an unlocked version vs Tmobile branded? Im told you may have issues with wifi calling/rcs/video calling/and visual voice mail....
2. How easy would it be once you get the unlocked version to flash the carrier software to make everything work and then flash back to original if needed to be for resale or warranty
The reason im asking is that samsung is giving a bigger refund on the unlocked version...

If you live in the US I think the unlocked version is just a SIM unlock. I think it is still the snapdragon version. Which means it will not be bootloader unlocked. I think you have to get the exynos version from an online retailer.

Note 9 was able to do this and I did it. I don't see a reason why you shouldn't be able o do it in Note 10+ once carrier firmware become available to be downloaded.

I pre-ordered the unlocked version myself and I have AT&T so it should be as easy as waiting for the carrier firmwares to become available on SamMobile and flashing with Odin. My interest is now with DeX supported with microsoft if Odin is even neccessary to flash firmwares anymore?

from what i can see on sprint i think they are using the qualcomm chip, i could be wrong, its labeled as SDM 855 Octa-Core SDR8150 and when searching that in google qualcomm documentation on the 855 pops up

Very curious about this myself. I preordered the unlocked version because that gave me more value for my trade in. I'm curious if I get the unlocked version and flash TMobile carrier software. Will I then get tmobile updates ota?

It's been the same for years now, hardware wise phones are the same, you'll need princey odin to flash unlocked/carrier firmwares. I buy unlocked and flash the carrier unlocked firmware. No bloat but it has the carrier specific radio. I prefer the native caller Id, no bloat, and the RTT over the carrier bloat and video calling. Google duo is better anyway

Are you TMO or ATT? I have accounts with both.
I know WiFi Calling, which is what I really need as far as carrier goes, is usually more difficult with ATT.
If you are TMO can you get WFC to work without flashing carrier?
How long do you usually have to wait for the carrier firmware to come out?

If you are TMO can you get WFC to work without flashing carrier?
How long do you usually have to wait for the carrier firmware to come out?

Wifi calling has no issues on unlocked firmware with tmo. At&t I'm not sure but if you flash the att csc and and cp files, I do believe that's all it takes. I believe you need to flash the at&T AP file.

My Note 9 is unlocked. Using on T-MOBILE with no issues with WiFi calling. I am not able to use the stock visual voicemail though which I would prefer. With T-MOBILE I'm forced to use their visual voicemail which really sucks. Does anyone else know if they're is a way to use the stock visual voicemail on T-Mobile?

I saw posts that allow you to do that if you flash carrier firmware
I just use Google Voice and forward unanswered calls to there

When I inserted my SIM it appeared to automatically install the T-Mo firmware, but that's the problem.; it forces me to use the T-Mo VM (which absolutely sucks) and not able to use the Samsung VM which is pretty nice. I had previously used the Note 9 on Verizon with my work SIM and I was able to use the stock VM. When I switched to T-Mo it forced me to use the T-Mo VM. I can't see a way to get back to the stock VM unless I'm missing something...

I go into the phone app call or SIM settings and find the call forwarding settings:
Then I do they conditional forwarding to my Google Voice number (I then, after setting up Google Voice, turn on Do Not Disturb for Google Voice, so I don't get there phone ringing twice)
Then GV serves as my VM

If you live in the US I think the unlocked version is just a SIM unlock. I think it is still the snapdragon version. Which means it will not be bootloader unlocked. I think you have to get the exynos version from an online retailer.

^^ What he said. Do not make the mistakes I, and many others made in the past - do NOT buy a US version from T-Mo, or from Samsung USA website, unlocked or otherwise. All USA versions are snapdragon based, and will have permanently locked bootloader - no rom flashing of any kind, no custom recoveries or improved radios. What you need is SM-N975F/DS Exynos version (unless you use CDMA carrier like Verizon or Sprint). It will have the same bands supported as Snapdragon one, with the exception of band 71, which you dont really need. T-Mo's B12 serves the same function as B71 (extended range LTE), and T-Mo made the tech available only in limited number of cities anyway. In all likelihood, by the time they roll it out in your city - you're gonna be thinking about buying Note 12 or 13.
Don't worry about software features like voice calling or any other - with all the custom roms and development available for Exynos version you'll be able to find yourself a rom that has any features you like and then some.

This is great advice ..... IF ..... you are looking to root and/ or do custom ROMs. But having done every release S9+/Note9/S10+ with Exynos it's NOT always that easy to get the CSC stuff right and working (and the development is often done by people who could care less about NA CSC because they don't live there).
Root / Unlocked bootloader = the Exynos device, like you said.
So what appears to be the answer (for the thread, assuming no root) after looking at all the answers in this and a couple of other threads is that the Unlocked US Samsung device is the same (or can, in worst case scenario, by Odin flashing carrier firmware, be made to do) device functionally as the carrier devices --- calling features, etc.
For me, the difference was going to be $300 bigger discount.

That's only true if you want to unlock the bootloader and root. The OP was merely asking about flashing carrier firmware on the US Unlocked version, which does not require root or an unlocked bootloader.

the bigger trade in value was a deciding factor as well for me...Well we weill see how it goes on the 23rd

I want to be able to root and flash TWRP on my Note 10+, but when i did this on my Note 8 i bought the N950N which was the korean exynos version and CRC support for t-mobile sucked ass, i want to make sure
A) what model do i buy for
- Rooting and stuff
- and best t-mobile network compatibility without going through all the dumb stuff

Same here. When Samsung stopped hobbling the OS, and added more features I didn't need root anymore. The extra $300 was my deciding factor. I have the unlocked Note 9. The only thing I have noticed aside from slower updates is that the camera sound can't be turned off independent of the global phone sound. Everything else works fine and I haven't noticed anything useful missing.

I was actually giving advice to all folk, considering purchasing, not just the OP....Also, just curious - how do you Samsung's locked bootloader on the unlocked Note (I hope you know 'unlocked' means SIM unlocked only) will accept firmware, signed by T-Mobile? It's not a given Samsung original bootloader, untainted by carrier branded modifications, accepts carrier signed ROMs. You may need to be using T-Mobile version of the bootloader, for it to accept T-Mobile signed images.
