I am currently running a G900A (AT&T branded phone with locked bootloader) i am in the process of buying a used S5 but not sure if the bootloader is locked. Here is the phone info that the guy provided to me.
Sm-g900f , g900fxxu1anc9 , 4.4.2
Like i said in on AT&T S5 so i am not familiar with the F models. Any info would be much appreciated.
Is it rootable through towel root? Can i use TWRP or CWM south this device. It is carrier unlocked and he is using it on T mobile (gsm) so I'm guessing it will work on AT&T since is uses GSM as well. Thanks for any help.
Edit: my apologies for posting in the general section. I thought i clicked on the Q/A thread.

Thank you. I've been searching about it and finding a lot of different answers. The T mobile guy at the T mobile store says if i flash a T mobile rom that has the lte band active then i should gain the lte connectivity. Hopefully that's the case. 3g is to slow for me. LOL.

Unlock all bands.
Go into the secret menu. Try downloading Phone Info app for this.
To unlock all the bands try this. Go to UE Settings/Settings/Protocol/NAS/Network Control/Band Selection and select LTE all bands.

Is it possible to flash a t mobile modem to my ATT i337 with MK2 through safestrap?
1) questions go in the q&a section
2) if it's a flashable zip then it should work, but I don't know if the modem is compatible, and I actually doubt it a bit.
Sent from Black<3's I337 running Hyperdrive
Maybe I phrased it wrong there was a thread about unlocking the t mobile bands on a att s4 a while back I couldn't do it because of the locked boot loader I was wondering if there is a way to do this via safestrap

Look in the general section, there's various threads about how to unlock the phone but the AWS mod seems to not work on 4.3 which i guess you need for LTE? Someone will have to confirm what that does. But you should still get H+ I believe.

Hey there folks
I have a SM-g900t that i got off Ebay (unlocked, KNOX counter Tripped). i got it because i hated my SM-G386W.
so i get this S% and start playing with Custom Roms and Loaded a rom from the SM-G900F ("ViSiON-X" or some crap) and while it works good, i cant connect to 4G anymore. phone cycles between HSPA, HSPA+ and 3G.
since im on Wind Mobile (inb4 Wind doesnt have 4G, they do, in specific areas, such as mine) i thought i'd flash the phone with the SM-g900w8 firmware from Wind mobile.
when i tried i got a Secure Check Fail: aboot message on the phone, and odin just immediatly fails.
im obviously doing something wrong here, and im guessing its going to be simple as hell to someone whos more experienced than i, so i thought i'd come ask here:
(TLDR here) How do i get my SM-G900t (that thinks its a SM-G900F at the moment) to think its a SM-G900W8 without getting "Secure check fail" messages?
before anyone asks: That samsung re-register thing is off.
to me it sounds like your phone settings are not on lte/gsm or lte/wdcma/gsm if your talking about additional 4g lte bands you could folloe this guide by fffft http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059

Hey, guys.
Thanks for reading.
I bought a locked S5 G900P from Sprint (BOD3) but I live in Brazil.
After a few days reading threads, I've finally managed to downgrade it via CWM (installing stock NK4 kernel and SM-G900P_NI3_ROOTED_ODEXED).
Then, I've unlocked it via SSU. Since I couldn't get any data, I tried a lot of workarounds (installing shohat rom, cm11...) but nothing. Then, I decided to flash the latest firmware available at sammobile: G900PVPU3BOF6.
No data from the latest firmware also.
Now, my phone is back to ShoHat V5 Rom (4.4.2), with G900PVPU3BOF6 baseband and NK4 kernel.
The signal icon on the top of the screen appears to be full (four bars) and I can see the phone carriers, but I can't register to mine (VIVO Brasil).
Does anyone know what I'm supposed to do? That's the configuration that got me closest to receiving data.
Please, any help would be greatly appreciated.
Again, thank you for your time.
Just saw that on my phone, despite using SSU:
NETWORK. BLOCKED
IMEI CERTI: FAIL, -9
Any help? Please.

Hey everyone,
I am currently running a straight talk variant galaxy s5, which is exactly the same as the verizon variant s5, just without the locked bootloadet. I know this for a couple of reasons.
1. I was able to root and flash twrp via Odin without safestrap.
2. I can boot into recovery without safestrap.
3. I can flash roms and make back ups in twrp without safestrap.
4. I can flash any verizon variant s5 rom, and they work flawlessly.
I have read, on galaxys5root.Com that cm 13 will work on all the s5 variants, except for Verizon and at&the due to there locked bootloaders. My question is this, if the locked bootloader was the only issue preventing cm 13 from working on a verizon variant s5, how hard would it be to port it without a locked bootloader? Or is there already a version of cm13 out for Verizon s5 variant?
In fact before I flashed a rom my phones model number said sm-s902L now it says sm-g900v. Not only that but YouTube before I flashed a rom would only let me play upto 720p, now it let's me play upto 1080p. And it's not a type o, it is actually playing in 1080p. It also recognizes and let's me over clock the full quad core processor. And I can verify that I bought this straight talk s5 from Walmart directly, and unboxed it out of a a walmart /straight talk box. What I think is that this really IS a verizon s5 sm-g900v, just with straight talk software on it, which gives it the unlocked bootloader.

On your phone go to settings => about phone and look at the build and baseband numbers. If they read SMG900VV you have a locked bootloader. If there is a KLTE in the build and baseband number your bootloader is not locked. If you bought your phone at a Verizon store or a retail outlet such as best buy, you most likely have a locked bootloader.

They say that the "klte" version is a generic gsm build. I don't know if that will work. I know I would have to add the vzw apn's, but i am also concerned about the radio files and modem that are in that build

Oops, I forgot about all the klte variants. I guess you would be looking for a build for the kltevzw. The CM thread says if your device is not listed to use the generic klte build, but I don't think I would chance that.

I am getting set to do the same - and it looks like there is a version for Verizon Gs5.
Scratch that - looks like there are no Verizon builds beyond KitKat so far. Getting the latest OptimalROM 15-5 instead.

It may work. In theory because the base models are the same and can run the same ROMs. But my fear would be that if you bork your bootloader your device would be hard bricked. You need the bootloader to even start the boot processes.
Anyone know which bands are supported by the VZW version? Is it only 2/3/4/5/13?

I just read about this. According to this review: http://www.pcmag.com/article2/0,2817,2500353,00.asp
"It (Verizon Wireless Samsung Galaxy S7) has LTE bands 2/3/4/5/7/8/13/18/19/20/38/39/40/41. Samsung unfortunately removed key LTE bands for the other major US carriers—12 for T-Mobile, 17 for AT&T, and 25 for Sprint—to make it difficult to use this model elsewhere."
I doubt it was Samsung that removed it - more likely, Verizon had them remove the others. Just a guess, tho.
Is there an ELI5 version of this thread? What is the importance of knowing which "bands" are supported?

Using the phone LTE in other carriers. Carriers 'own' certain frequency bands which are used to communicate with your phone. Your phone and the tower need to be able to use the same frequency band in order to communicate.
Most phones work on 2G/3G world wide (except on CDMA carriers like Verizon, generally most phones don't use the tech/frequencies for verzion nor would Verizon allow then on their 2G/3G bands of they did). But LTE is new enough that most phones don't support the 20 odd frequency ranges used (2G/3G use less then 10 combined for most of the world).

The modem supports all the bands, Verizon disables it in software. What a bummer! I will suggest you to buy G950U or US cellular model.
Or flash the firmware of the carrier you want to enable the modem which has been successfully posted on a few xda threads and other sites. All snapdragon us variants can be cross flashed.

You'd have to check on the s8 forums. An s7 probably would as I think only the Sprint and tmo phones were simlocked. Not sure though as I've only had my ST phone and read the vzw phone being used on several carriers.

So are you saying that the actual bands are software based not hardware based. So all we have todo is flash the right ENG and ROM and wala I have right radios for my carrier?? US Based.
Yes, flashing the fw of the carrier loads the correct radio drivers. The radios are hardware based, but locked down by what the firmware has the instructions to look for and run.

Great explanation, I’m new to this stuff - we all have to start somewhere right?
So is root required to flash? The reason I ask is that I’d like to buy an S7 but I want to be able to WiFi hotspot tether without carrier provisioning and some versions of the phone allow it while I’m pretty sure others block that (like att)...By the way do you know which version would be best to flash to for WiFi tethering and ALL LTE bands made available? Thanks!

I use the hybrid rom that is loaded with vzw and debloated custom to my needs. It has tethering enabled. You'll just need to use root long enough to get the flashfire setup going and then once you're done it is unrooted. You'll have to check other threads regarding performance tweaks if you decide to stay rooted.

Using the engineering kernel for nougat you can achieve toy, but it's buggy and slow since it wasn't meant to be used for daily devices. That's why the hybrid ton was developed to show some root uses without needing to keep root, like removing bloat permanently or getting the tethering service setup.
