There are so many varients of the SM-G925, all with a letter at the end, I am looking for a Edge that will work on AT&T , I want one with an unencrypted boot loader.
What version should I get. I bought one on Ebay it said it was a SM-G925 (with nothing at the end) is this even a model, or am I going to get something else you think?
Ps. it says its factory unlocked, but I am not sure what frequencies and modles go together.
please assist.. thank you
Yes there are many SM-G925_ models, where the letter _ changes depending on network.
I'm in Japan with a softbank 404sc phone, the SM model is SM-G925z.
If you wait until it arrives, you can go through the boot loader steps here ( search google for galaxys6root highonandroid how to root s6 edge), without downloading anything until you get to an aqua-blue screen which will tell you the model.

If you care about good signal reception, without doubt get SM-G9250. It's modem and bands it supports is superior to any other variant. I had slower and worse connect with G925F.

Android newb... will I lose anything flashing my unlocked international phone on AT&T
Hi everyone, and thanks for all the great info here. Let's assume I have my "how to root" links bookmarked and ready to go, but like a good boyscout I want to understand the gotchas/subtleties before I cliff jump. I'm also within my 15 days to exchange my s6edge AT&T for an unlocked one at Best Buy, which I plan to do today... :highfive:
(I'm technically savy, but a real newb in the world of android versions, manufacturer changes, and carrier versions and conflicts...) :crying:
1) How do I do a full ROM-level backup before beginning my adventures in rooting? Titanium Backup is no good since I need root to use it. I'd like an iPhone-style backup that I can just restore should I brick my phone.
2) After I exchange my phone I'm going to immediately airplane-mode it to prevent autoupdates (my current phone already autoupdated to unrootable OF4)... once I root how do I effectively get-latest? I'd obviously like the latest security updates, and 5.1 if I can manage it, and to maintain root.
3) AT&T doesn't have 5.1.... but if I go unlocked then can I run 5.1 on AT&T? (I've been iPhone forever -- carriers messing with you is really foreign to me). On a related note, can AT&T send some update/profile-change OTA to my phone that will conflict with updates I'm doing locally? If so any tips to avoid this?
4) An unlocked phone will perform just as well on AT&T as an AT&t phone, right? (looks like the 925F has all the AT&T bands and more, whereas the 925I is missing 1 AT&T LTE band)
Thanks for any info, help, and/or pointing me to resources where I can find the info, in advance. I'm technically savy, but a real newb when it comes to the gotcha-ridden ground of android and carriers.
Thanks again.

So can I upgrade a 925F to 5.1 and use it on AT&T? I'm trying to work out if AT&T has _all_ edges locked down or just the official AT&T versions.

At&t does not have the power to lock down all variants; only the variant with its branding. Just make sure 925F is compatible with the network of you want to use that variant.

Thanks so much. Is there a reason I can't to seem to find any people running 5.1 or rooted phones on AT&T? Just that not many people are buying unlocked phones?

The at&t variant is the only variant not to receive 5.1 yet. It has nothing to do with root and everything to do with at&t's corporate policies. Most people who use a smartphone in the USA buy it through their carrier. So those users on at&t likely bought there phone from them. This is why no 5.1 for them.
Hey everybody,
So recently i bought this international unlocked Galaxy S9+ (SM-965F/DS Exynos processor) off Amazon and it's great, everything is fine with the one major exception being that at home my signal is pretty poor and i get extremely delayed text messages coming in and calls taking forever to dial out or failing to connect. Not a problem, i'll turn on Wi-Fi calling, right? Wrong, option isn't available, some detail: I'm in the US on T-Mobile, updated to the latest Pie OS update, i'm very tech-capable and used to do tier 2 tech support for Verizon. Long story short, I've tried everything in the book including FDR and fresh setup as well as clearing system cache etc. and it's looking like the ONLY solution to get Wi-Fi calling (and subsequently VoLTE that i didn't realize wasn't enabled until researching and checking myself) enabled is to flash the ROM with a T-Mobile OS. Unfortunately i'm coming up negative trying to find the firmware for this phone. Plenty of resources out there for the SM-965U(Snapdragon), but none for the SM-965F(Exynos) as of yet as far as i can tell (and before any ignorance jumps in here as i've seen on other threads, NO the SM-965U software will NOT work on this model phone as it runs a different processor, non-Snapdragon Exynos chipset)
So, that all being said, is anyone out there working on a fix for this, is it likely i'll ever get a fix for this, and/or is the fix already available and I've just completely missed it? Any information or help would be greatly appreciated. Thank you for your time and consideration.

I'm currently researching the very same issue... So far i hypothesize , with no knowledge, that if it is rooted, you can then change the csc settings and configure it for TMO, thus enabling WiFi calling. If someone can confirm, that'd be great, otherwise i'm trudging slowly to verify.

Well i looked at this and it looks like a non-stock rom i'm sure wrought with problems that unfortunately is not helpful. My goal here is to have my phone work and continue to get standard updates with original and licensed (more or less) software and have it actually work. I'm not interested in a full OS replacement pre-loaded with a bunch of adblockers and other crap the designer thought would be useful, just want my standard features enabled and nothing else to change if at all possible. Also, if you believe my statement here is in error please explain, your one line really isn't very helpful, and nowhere on their website is there any description as to what tekhd detonator does / is supposed to do / what it will break. I'm certainly not risking bricking my phone when their own website says under all of its S9+ related material that it's for Snapdragon which the variant i have again doesn't use Snapdragon.

This is going to be a hassle trust me. even with the Snapdragon models from different CSCs VoLTE and Wifi Calling do not carry over. An ATT 965U would have to be reflashed with the TMobile CSC and USERDATA files to get access to TMobile features. U are trying to do this with an Exynos model. I think you would have to root and install a custom firmware that has the TMobile USERDATA embedded.
Good luck.
can the U1 be flashed to the verizon u firmware? i thought i read someone tried this, but suspected it didn't work because he had previously used the phone with verizon with the unlocked firmware...

You can flash the G965U onto the G965U1 and vice versa. It's been well documented that this will let us go from one carrier firmware to another as well as let us have the unbranded carrier firmware. The only catch to this is the bootloader version of the firmware your wanting to flash. The firmware one wishes to flash must have a bootloader version equal too (or greater then) what is currently on the phone.
If your trying to ask about flashing the U1 onto an exynos variant then the answer is definitely no. You can't flash firmware from a different model onto a different model.
Hello everyone,
First i want to thank everyone at XDA Forum community for being a great resource of information and providing great community support.
I purchased Moto G Power 2021 (Android 11), locked to verizon. I am trying to unlock it to be used on other carrier such as tmobile and for traveling. I came across websites that sell the unlock code.
However the problem is when NON-Verzion sim card is inserted in the phone, its does not ask for sim unlock code. Therefore not sure how to carrier unlock the phone.
If someone has insight how to go about network sim unlocking the phone, that will be very helpful and greatly appreciated. thank you
i'm in the same boat
Verizon is a cdma network and boost is a gsm network. The radio files included in your Verizon firmware probably aren't capable of connecting to a gsm network as the two networks operate on different frequencies and I assume employ different connection/communication protocols. You MIGHT could flash the firmware from boost for the same model, but even doing that could be frought with problems like if the boost firmware is older then anti rollback protection wouldn't allow it to boot when flashed, and I'm not sure if the Verizon and boost versions have exactly identical hardware, which could cause massive problems even if it did flash and boot. For example, this model phone has like 3 different touchscreens and using a firmware with the wrong touchscreen drivers would render the touchscreen useless. If you're determined to carrier unlock, be ready to do some serious digging and read everything you possibly can before doing anything that could have irreparable consequences. Best of luck

What's the model number of it?
I'd imagine you maybe could flash the firmware for the carrier you want to switch to using the fastboot flash method, the rescue tool will only flash your phone's official firmware. But you can download different builds for different carriers off of lolinet and if they don't work you could flash the correct firmware to get back to where you are now. You might flash your official fw with the vendor stuff from the other carrier's rom if flashing the whole firmware doesn't take or isn't compatible in some way.

Hello thank you for your advice, unfortunately i don't have much experience in flashing different firmware. Also i think it causes too many problems, which are difficult to fix. Therefore i was hoping if there is a way or hidden menu i gotta go into will activate the phone to ask for unlock code when different sim in inserted.

Tmobile is much cheaper in comparison to other carriers. I think once the phone is unlocked it will work pefectly.
When you insert a non-cricket sim card does your phone ask for network unlock code?

yes, it does. it is network locked and "not eligible" for unlocking.
I called Cricket, but they won't unlock it because it hasn't been on their network for the six months they want.
I bought the phone really cheap on ebay for its long battery life., it's damaged (bent as if someone sat on it) but works fine, no cracked screen or anything else. I want to use it on my T-mobile account.

I believe the issue of why it's not asking for unlock code may be two fold. For one, since you mentioned you bought the phone locked to Verizon, was it purchased from them or was this a second hand purchase like ebay/FBMarketplace etc? Because either way you'll have to meet the carrier minimum requirements for unlocking a device, the former scenario of you having bought the device yourself being much easier to deal with than the latter case.
Second, as was mentioned here earlier, you may be dealing with different hardware. I'm not sure if the G Power 2021 all contain the capabilities to run all network frequencies or not. But if it's hardware restricted or dissimilar to other models in kind based on network carriers & OEM agreements, you might not be getting the chance to input an unlock code because the third party SIM inserted may simply have no way of being recognized by the device, either from a software vendor blob limitation, a hardware radio restriction or lack of capable hardware, or both!
I know this is an old one, but was a solution ever found? Currently stuck with Moto G Power 2021 as well, locked to cricket. It doesn't prompt to enter a code either.

Only free solution is to meet all of Cricket's requirements, and have them do it for you. Otherwise a 3rd party company can do it, for a fee

That sounds better honestly. I'm open to using a 3rd party company, but point me in the right direction if possible. I've been looking, but no idea what service to use if the moto g power isn't asking for a code.
EDIT: Actually, I finally found someone at a reasonable price to do it, and it worked, phone unlocked. They used USB Redirector and did their thing. Took all of 10 minutes. Now I just need to flash a different rom to rid myself of the cricket bloatware.
Have you tried another sim card in your phone, I'm pretty sure these all come unlocked by default. Mine was bought at US Cellular & I'm using a prepaid Verizon service by simply throwing the new sim card in the phone. It works perfectly as it did with US Cellular with no setup or changes required. I believe all moto g power phones do this I had a regular moto g power not 2021 that was on Verizon I switched to straight talk the exact same way.

Actually, another random question, but is there no way to update without unlocking the bootloader? LMSA? Just making sure.
Since the Galaxy S6 Edge days I've been getting AT&T branded Samsung phones. This time around due to initial perks of a trade in were better for the unlocked version of S23U, I went ahead and pre-ordered the unlocked version. Are there any drawbacks anyone has experienced with the unlocked version that would warrant me to cancel the order? Are there any AT&T features such as visual voicemail, personal hotspot or HD voice that isn't compatible with the unlocked, non carrier version? Any help would be appreciated as i believe I can still cancel the order.
Thank you.
With an unlocked phone, you cant call. But if you add a sim card into it you can do anything such as mobile data, call, hotspot, etc. An unlocked phone can work on any carrier. But it is still the same thing as an at&t version unless you add the sim card in it.
So I assumed if i insert my AT&T simcard it'll work just like an AT&T phone?

That's what I have done for every phone I have had since the S7 Edge on T-Mobile. Still using the same simcard since I started out with the (S7 Edge), then Note 8, S20U, S22U and now S23U and has worked fine with T-Mobile but without the carrier bloat. The only downside is Unlocked versions always get the updates last.
You can always flash U (carrier firmware) that is bit different from from U1 (factory unlocked) firmware. This way you'll get exactly the same experience as for the phone of any carrier directly. You can always switch back and forth with data wipe.

First time Sammy user here, so possibly a stupid question but... from my search it appears that other than carrier bloatware you don't loose anything by going to U1 firmware and possibly gain faster updates. Is that a correct? Seems to be the case for WiFi calling but what about ATT wifi hotspots for example?
Unlocked phones were useful for sticking local SIMs in them for international travel but with the new international plans pricing is actually reasonable so it is not worth the hassle.

I was in the same situation as you, and ordered the Unlocked version this time instead of the AT&T version. I am happy to report that everything is working. Visual Voicemail (Samsungs App), Personal Hotspot (aka Mobile Hotspot), HD Voice (VoLTE), and WiFi Calling.
I'm curious if anyone knows the compatibility of a US Verizon s23 ultra and T-Mobile's network. I assumed they would be compatible as long as its carrier unlocked however I'm having issues getting my Verizon s23 ultra to accept my t-mobile sim. Any insight from someone with more experience is welcomed.
Verizon locks the phone for 60 days. After that, you're good to use whatever SIM you choose (you may have to flash the U1 firmware to get all features working though).

That sounds like it's still locked to me? Are you using the pSIM or the eSIM? There have been some reports recently that the pSIM gets unlocked and the eSIM remains locked to the original carrier but if you're trying to use the pSIM and they say it's unlocked, I don't know.
