AT&T G900A, locked bootloader, can I move to Tmobile, and rom? - AT&T Samsung Galaxy S 5

Hello, I currently have a few Samsungs (old, S3), and they are all rooted (I am familiar with rooting, firmware loading via Odin, TWRP/CWM, etc). I have read a large number of posts on how the Galaxy S5 after 5.X is boot loader locked. I was gifted with a AT&T Samsung Galaxy S5, with the Sim unlock code (and I would like to use it), however, it has been updated to G900AUCS4CPA2. To add insult to injury, I am on T-Mobile.
Forum posts have indicated that the only requirement to move to T-Mobile is to change the sim. However, it would be nice to use the wifi calling, etc (or at least a T-Mobile rom). Even though the bootloader is locked, is there a way to install a Tmobile S5 5.X or 6.X rom? It seems like installing different AT&T roms via Odin is possible, as long as they are >=5.X. Is there a way to install a T-Mobile rom via Odin?
Barring all of that, is there a way to install a totally generic rom, and not be AT&T branded/bloated/etc?
Thank you.

No. The locked bootloader prevents all of that.

Ok, but it came with 6.0 and I downgraded to PA2. So there is no way to install anything else?
Backstory: I initially tried and failed to install 4.4.2, and with more reading realized that I was on the "bootloader locked" 6.0, and that I had thrashed the current rom that was installed. I then found an XDA post on moving back to 6.0, but it starts with PA2, which installed successfully and the phone is on PA2 (the rom I posted in the beginning of the thread). So, I can seemingly install AT&T roms, as long as they are 5.0+?? I just can not move anywhere else??
Thank you for your input.

[Q] Flashing KitKat on a Moto X with 139.12.35.ghost_row.AmericaMovil.en.PR

Hello!
I'm currently stationed in Singapore and bought a Moto X about a month or so ago from eBay. While I am anxiously waiting for my Moto X to receive the 4.4 update, I realised that the system version (after the previous camera update) is 139.12.35.ghost_row.AmericaMovil.en.PR, which I found to be a Latin America version after some searching on the forums and Googling here and there.
I also found this thread, where OP said that they can be flashed over to either the T-Mobile version. Does this continue to work for the 4.4 updates by T-Mobile or AT&T, and would there be anything else required for flashing? (I saw something about flashing new radios and all, but was quite confused by contradicting explanations and suggestions :/)
Thanks in advance!
// EDIT:
To add on after a bit of searching, I realised that I am allowed to unlock my bootloader, despite claims from the original retailer on eBay that the phone came from AT&T (which is notorious, even here, for their stance on bootloader unlocking). What gives?
I got the same Moto X from a buddy yesterday. I did a lot of searching and also discovered the thread about the phone being flashed to t- mobile.
I fooled the steps on another thread titled " Return to stock 100%" out something like that...
I downloaded the correct Att firmware and with the use of RSDLite, I successfully flashed my Moto X to ATT.... it took less than 10 minutes. And as soon as it booted up, I got hit with the "update available" message ( kit Kat)

Thanks for the information!
I've successfully upgraded my phone to the Verizon version (minus all the bloatware that I hastily blasted off), with root and TWRP. So this is what I did, for future reference:
It seems that AmericaMovil versions are not bound by the AT&T's locked bootloader policies, and other Latin America versions are probably free from the restriction too. So I managed to get my hands on the Motorola Fastboot and unlocked my bootloader. TWRP was installed (remember to use 2.6.3.1 and above for 4.4 support), and then flashed the Verizon system dump available here. Root was installed by TWRP.
After getting on the device and setting things up, I rebooted to recovery to remove lots of bloatware (available in /system/app and /system/priv-app). Had to remove some of them through Titanium Backup as the file names were not always indicative that it came from Verizon. I made the extra step of killing the god-awful boot animation that they had by replacing it with this.
And... that concludes my experience with this, I suppose.
I've been looking through a few threads and I am not comfortable enough to flash the T-Mobile rom over my AmericanMovil one yet.
I can't seem to find step by step instructions on how to do this.. Would anyone like to explain it from the ground up?
My understanding
1) unlock bootloader
2) flash a recovery like twrp or cmw
3) flash the rom that is given in the OG post here http://forum.xda-developers.com/showthread.php?t=2477180
4) this should now give us the t-mobile version of things and we should be able to do the standard OTA from there?
[Q] So can this all be done without ever having to root the phone?

I'm not too sure whether flashing via TWRP/CMW will allow you to get OTA, unfortunately. Which is why I went straight for the Verizon system dump. But yes, you can change firmware without ever having to root the phone. Heck, I think there's a guide on restoring mentioned by @plmiller0905 below that will allow you to do it without unlocking the bootloader, even.

I believe the bootloader does have to be unlocked in order to flash a different firmware.

Yeah after doing so more reading.. (at least the way I'm willing to do it) is to just unlock my bootloader and then using RSD Lite (Which i still have no idea what that is / where it is) flash an SBF found here (http://sbf.droid-developers.org/ghost_rcica/list.php)
I guess following this video somewhat http://www.youtube.com/watch?v=Fr0JHSAXJDI#t=15
Does that sound right?
Should I flash the TMO_RETAIL_XT1053_4.2.2-13.9.0Q2.X-116-X-17-57_MR1_CFC.xml.zip
Or just jump straight to the 4.4 version TMO_RETAIL_XT1053_4.4-13.11.1Q2.X-69-3_MR2_CFC.xml.zip
??
As far as I know, the use of RSD Lite doesn't require an unlocked bootloader (at least, that's what it shows in the video you showed me anyway), especially since these are images supposedly signed by Motorola themselves. Let me know if you've found something else?
As for your question on which to flash... I'm not sure, but you'd skip a lot of the hassle if you could flash 4.4 straight, so how about trying that?

Rsdlite is a shell for a flash boot flash supposedly with an XML doing all the steps together. Just makes it easier.
You need unlocked boot loader only to flash an image that doesn't match your current boot loader. So if you have a. At&t phone you can only flash at&t images by rsdlite. But if you unlock your amerimovil phone you can flash any xt1058 image I think. So amerimovil could take say a rogers or at&t or telcel image. Not sure if T-Mobile image will work on a full rsdlite flash as it is an xt1053 image. I think you can flash most of a T-Mobile image by twrp but not by rsdlite not sure

So if I flash the at&t image found here (http://sbf.droid-developers.org/ghost_rcica/list.php), would it come pre-loaded with all the bloatware AT&T has even though I'm not using AT&T network?

yes of course. think about it like if you took a dell windows 7 install CD , and put it on an HP. all the dell customizations would still be there.
obviously since you have unlocked bootloader, once you do the RSDlite you can always flash twrp, and superuser, and delete all that stuff. but then you wouldn't get updates again. i dont think the at&t image is really THAT bad. though i've heard the rogers one is better (though maybe not 4.4 yet)

Yeah unfortunately that's what I thought. Hence why I would of liked to flash the t-mobile image but I'm going to hold off until someone that is a bit more adb savvy then myself tries it out. I wouldn't know what to do if I ended up soft bricking my phone
Well it didn't take long to try it out myself...
It worked out!
I used this thread here http://forum.xda-developers.com/showthread.php?t=2446515
I downloaded the Tmobile 4.4 Image and used RSD.
All you have to do is unlock your BL. (Note: I was completely bone stock with NO root and NO special recovery like CMW or TWRP)
Have all the proper drivers installed, enable USB debugging in developer settings on the phone
Go into Fastboot on the phone
Plug in the phone and just follow the video
I do not take any responsibitliy if you brick your phone. It is fairly easy process and took only a few mins.
Hope this helps!

I've been doing some research on this since yesterday and I've been hesitant on doing it. I saw in your last post that you successfully flashed the TMO 4.4 ROM on your AmericaMovil phone, so I have a few questions for you before I go ahead and do the same:
1. Can you please confirm that your model is XT1058 and not XT1053?
2. Does the TMO ROM have the TMO boot logo and any TMO bloatware?
3. Does the TMO ROM have the Tethering & portable hotspot option under Settings > More?
4. Does the TMO ROM have the Mass Storage option under Settings > Storage > | > USB computer connection?
5. Have you been having any radio problems since you flashed the TMO ROM?
I wonder if I install the ROM in here http://forum.xda-developers.com/showthread.php?t=2477180 using RSDLite, would I get the OTA update to 4.4? The reason I want to install this ROM is because it only flashes system and boot.img without flashing bootloader, modem, logo etc... and I know the XT1058 radio is different from the XT1053 radio, so I've been reluctant to flash a full XT1053 ROM on my XT1058 phone.
But what I also would like to know is if an OTA update would flash a full ROM or not. In other words, if I flash the ROM above and then OTA update to 4.4 and the OTA update flashes the full ROM including the radio, I might as well flash the full 4.4 immediately.
What do you or anyone else think?
I'll answer to the best of my ability. heh

Mine was an XT1058, and has been flashed to XT1060. (I didn't notice that T-Mo had a 4.4 ROM on the list, so I went straight for the flashable ZIP for Verizon instead. silly me.)

At least according to this article, the TMO version shouldn't have any bloatware.

There's no reason why there shouldn't be; I'm seeing it on my Verizon version.

I can't say for sure if you'll face any problems, but I flashed the T-Mo radio provided here with my Verizon ROM, and I had no problems connecting to my network in Singapore.

Thank you for your answers!
Regarding Mass Storage, the reason I'm asking is because I don't have it on my AmericaMovil ROM.
The ROM is basically exactly what you get when you buy the T-Mobile version.
I figured the radios are nearly identical from the AT&T version and the T-Mobile version so my XT1058 is running on the XT1053 radios. There is no bloatware. tethering is there but I'm not sure if t-mobile will allow it. There is NO tmobile logo that comes up on boot. USB connect to computer is there.
As for the radio section again.. I was getting only EDGE in my house before I switched to this ROM (Meaning when I was on the ORIGINAL XT1058 image) and I am still getting only EDGE in my house.. Unfortunately I haven't left my house since yesterday flashing the image but when I'll be back at work in NYC and should see '4G/LTE' over there.
We'll see.

I've always been on T-mobile network. Both when i was on original XT1058 AmericanMovil system version and still on T-mobile when I switched the image to XT1053.
Back on my Nexus 4 though.. I would have HSPA+ in my house.. So I thought it was a bit odd that as soon as I received this phone that I wasn't getting anything other than EDGE..

[Q] Kitkat update after SIM unlock

Hello everyone,
I have an AT&T galaxy note 3 that has an unlocked SIM, I unlocked using a code from cellunlocker.net. I'm using it on MetroPCS. I have the gps issue that others have mentioned on the forums and I wanted to update to Kitkat as I heard it fixes the issue. Only problem is I obviously can't get the OTA update from AT&T. Kies says that my phone has the latest firmware (MJ5). I tried using the ZIP that was posted on the forums (official not beta) but I got the sideload error. I also went into best buy and tried updating it at the Samsung desk and they said they couldn't pick up the phone in "smart". Not sure what that means but they said it has to do with it being unlocked. The phone is not rooted and never has been. Am I missing something? Also, if I do succeed in updating will I loose my SIM unlock? If I do can I use the same code I used previously to unlock it?
Thanks!

no you dont need an AT&T sim, updated mine with an Aio/Cricket sim card in and it worked fine. Try going recovery then installing the NB2 OTA first then again with the NC2 OTA, a quick search should fine you these files on XDA, I did it a month or two ago fine.
---------- Post added at 03:02 AM ---------- Previous post was at 02:55 AM ----------
Here are the NB4 & NC2 OTA files, please note these are not mine, they are from other XDA posts
NB4: https://www.dropbox.com/s/zccryfxycby1iq8/2400258.cfg
NC2: http://www.mediafire.com/download/mb...o2/2400258.zip
I believe install goes as follows:
1. copy file to phone
2. rename to update.zip
3. boot recovery
4. wipe data/factory reset
5. install update file
6. select update.zip
7. restart follow install
8. do steps 1 to 7 again, except copy over the NC2 files
hopefully someone else can confirm this? As I did this a couple months ago and don't wanna mess up the op's phone.

Same problem here too, i have it running on metro, tried the ota update and it gives me "software update interrupted" message. Ive benn trying to find a way arround it but i dont know how, let me know if you get it . Thanks
So I finally got my At&t note 3 unlocked and on MetroPCS updated to KitKat!
Here's what I did:
1. I was on MJ5 so I couldn't update straight to KitKat NC2 without first updating to NB4. I tried to install NC2 first and got an error. I found a very useful thread here with links to all the firmware versions http://forum.xda-developers.com/showthread.php?t=2693375 Many thanks to Walter.White!! I downloaded NB4 and installed it using ADB. In ADB you'll need to type "adb sideload xxxxx.xxx" (x is the filename of the update) without the quotes.
2. After successfully installing NB4 I downloaded NC2 and installed it the same way, and voila! Make sure to remane the file to "Update" first. When your in ADB type "adb sideload update.zip" to install the file. Now I'm running KitKat.
Note: My sim remained unlocked just like I had figured so no surprises. Just check your apn setting are correct after upgrading so you'll get good service (LTE, etc..).
Can anyone confirm?

G900A and G900AZ

I read that the Cricket Galaxy S5 (G900AZ) is a rebranded AT&T S5 (G900A). Has anyone tried ODIN flashing the stock AT&T rom on the Cricket model?
For instance, i have read people flashing the Tmobile S5 stock rom on the MetroPCS version and it works fine even though the model numbers are slightly different. It changes the phone into the Tmobile version.

Did you ever get an answer to this?
NO, but....
The Cricket S5 is indeed a rebranded AT&T model. I have both of those models including a LA G900M (TTT.) Major difference is nowhere near as much bloatware, and most importantly an unlocked bootloader. The only advantage would be upgrading to MM if you want stock, since the January update still has it on LP. You're better off trying a LA stock ROM though (I say this because they use the same custom recovery) But cutom ROM's can take you there as far as 7.1 Nougat right now.
I just recently rooted my Cricket model with CF Auto-root (klteaio), flashed the latest TWRP (klte) recovery and installed Xposed Framework (by dkcldark... wanam custom won't work.) Had a little of lag first couple of days, but I guess that's to be expected. Hope this helps in some way.

You could always try it. I don't know exactly how well it will work.
You would have to be rooted FIRST on the G900A in order for FlashFire to work. If i remember correctly anything already on LP can't be rooted or downgraded back to KK.

Y'know what would be really nice???: Seeing that android updates are only good for 2yrs on a particular model after its initial released, and the given the fact that most carries plans are only 2yrs; wouldn't it be nice if (for sake of argument in THIS thread) AT&T would release a firmware for their phones, that would unlock the bootloader and possibly SIM unlock the phone as well. I mean after 2yrs the device is paid for and quite frankly no longer belongs to them. I hate the idea of being forced to either get a new device once my plan has expired or use MY phone with the carrier its branded under. Of course it probably has everything to with them making their money from those of us who can't do without having a new device every year.
So I can pull a copy of the G900AZ engineering firmware I found, but I doubt we'll be able to flash it. What is was thinking is that we use beaups CID changer to make our device into one similar to the cricket wireless one. Since it is essentially a dev edition of our phone.
You cant just flash a unlocked bootloader to a locked bootloader phone. A specific explout must be developed to defeat the bootloader. Simply shashing over it will never work.
The G900AZ is just a rebranded version of the G900A though. I don't think there are any glaring differences like there would be from G900T to G900A. If the aboot does flash then it would be a simple unlock.
@NavSad @AptLogic
If you wanna try this, here's a link to their firmwares:
https://www.sammobile.com/firmwares/database/SM-G900AZ/
You'd most likely need to extract the correct files and be on the correct versions before flashing these.
Apparently, something similar happened with the T-Mobile Galaxy S6, where the MetroPCS firmware was flashed on the T-mobile firmware.

I tried ODINing the G900AZTUU3BOG3 firmware, and it immediately returned a SECURE CHECK FAIL: aboot
I'll try using FlashFireon it tomorrow during my batch of tests.

Just so I can get an idea of what everyone's fuse values are, do you mind telling me what you see after RP SWREV in Download Mode.

Mine are S1, T1, R1, A2, P1. I'm on Lollipop 5.0 with with ability to downgrade to NCE.
Also @AptLogic, maybe try through stock recovery, just as a precautionary measure.
P l e a s e do not try this
So I tried using FlashFire to flash the G900AZ firmware and I HARD BRICKED MY PHONE.
If anyone wants to give me advice on how to unbrick it PLEASE DO because I have to put all my development on hold indefinitely until I can unbrick it or buy a new one (which isn't likely because I don't have the cash for that right now).

I would try this method:
Grab a sdcard
Grab a debrick image here:https://www.androidfilehost.com/?fid=457095661767140194
Then put the sdcard in your computer and use Win32 DiskImager to write to the sdcard. After that, put the sdcard in your phone and boot into Download Mode.
If your phone isn't fixable using this method you'd have to try JTAG.

Is the debrick image just the first 200MB of the phone's data?

Is it impossible to flash an AOSP rom on a rooted AT&T S5 Active?

Hello!
I've done some reading and having not gotten a satisfactory answer I thought I'd throw my question out to the community.
I'm currently running Twisted Lollipop v7.
I can Odin back to stock 4.4.2 whenever and redo towelroot and install safestrap etc.
I've been unsuccessful at flashing an AOSP rom and wanted to confirm once and for all if it is truly impossible to flash Blisspop or Cyanogenmod or Sonic or any of those I enjoyed on my trusty old S3 onto my unlocked At&T S5 Active.
If it is not possible I will get rid of this unlocked AT&T S5 active and get a used what? The T-mobile variant? The international variant? I just want to be able to flash whatever the hell I want without too much hassle! I do like the phone other than that though!
Looking forward to any advice!
Thanks!

No you can not flash any AOSP roms on a device that runs safestrap, the bootloader isnt unlocked so you cant install a custom recovery the closest thing to a recovery is safestrap, and with a locked bootloader you can not install kernels which is why you cant install AOSP based roms.

Thank you for your response!
Blues! It's what I suspected. I intend to offload this phone as a result and get another. Which variant would you recommend I get so I can flash happily and not worry about a locked bootloader? The SM-G900F, or what else would you recommend?
Thanks for your help!

Any phone that has a carrier would be locked for the most part, i know sprint and maybe t-mobile usually don't lock there bootloaders, but that doesn't mean anything they could still be locked down. Your best bet if your looking to get a new phone for whatever reason stick with the ones straight from samsung the international versions. they usually don't have locked bootloaders.

Is there full bootloader unlock/root available for the ATT S6?

This is one of two phones I'm looking to buy after work today to replace the Verizon S5 I broke last night. Wanting to make sure whatever I get can be bootloader unlocked and fully rooted, otherwise I'm just getting another S5 so I can continue using CM ROM.
Thanks!
i think yes following this steps
1-root it using pinpong root
2-unlock the boot loader using ADB on pc
3-install twrp
4-install SU
watch the video it did it with a note 4

No.
No bootloader unlock at all.
Therefore no non stock based custom roms.
Root is available via ping-pong on very early lollipop builds, but unless you specifically know you are getting an old, non updated device, it's not likely this will be an option. Some newer builds of lollipop can be rooted by a tethered method. There is a root method for some MM builds. Think one is under development that has yet to be confirmed or released for N.
Very strongly do not recommend ATT version of this device if rooting and custom ROM's are important to you.
If you're looking at an international, rather than att model, then you're in the wrong forum.
