Sorry if these are dumb questions... I have searched unsuccessfully for answers here and I am new to the forums and to Android... not sure where to ask this...
I just bought a new (unsold stock) T-Mobile Samsung Galaxy S5 (SM-G900T) phone and activated it on the T-Mobile network. The phone came with G900TUVU1ANE6 (4.4.2) from the factory. After only a few hours of operation T-Mobile has pushed an unnamed update to the phone which I assume is G900TUVU1GPE1 (6.0.1) Marshmallow. I have postponed installation of the update but don't know how long I can postpone it or if I can prevent its installation.
Will installing Marshmallow cause my S5's bootloader to become locked? I ask because I found this on Wikipedia (link not allowed) "As of Marshmallow, the Android Compatibility Definition Document contains new security mandates for devices, dictating that those that are capable of accessing encrypted data without affecting performance must enable Secure boot and device encryption by default".
Or is my G900T's bootloader already locked? I ask because I found this at root my galaxy dot net (link not allowed) "If your device’s bootloader is locked then you will get the update via OTA. [...] If your device is rooted or bootloader is unlocked then you have to manually Flash / Install Official Android 6.0.1 Marshmallow Firmware On T-Mobile Galaxy S5 using Odin Flash tool".
The second question worries me more. I bought a T-Mobile S5 because so many sources claim the G900T bootloaders are unlocked. Now I'm unsure. Is there an easy way to determine if my bootloader is locked or unlocked? (I have Heimdall available on a Linux laptop but no windows machine).
I hope to install CM10 or CM13 on my S5. Thanks in advance for any definite information or guidance anyone can provide.
I'm thinking about buying an S5 and am wondering this as well.

After installing the latest firmware, you can still flash custom ROMs, you can still root, etc.
Just look in the Android Development sub-forum, and you will see several custom ROMs for MM on the SM-900T.
You can also flash ROMs from the International S5 forum. I've never flash a CM ROM, but there are several on this forum that have and do.

G900T T-Mobile's bootloader is not locked. I've downgraded from MM to KK without problems. I flashed RR MM without problems
No brother . I mean if I need to root s5 T-Mobile than shall I downgrade it first or I can easily do it on marshmallow.
Can u tell me any authentic root process!
Thanks
http://forum.xda-developers.com/tmo...l/root-how-to-root-sm-g900t-firmware-t3358190
It's exactly the same process on MM as it is on LP or KK.
I rooted my G900T about two weeks ago. It had MM the latest patches and everything, so you don't need to worry about the bootloader ever being locked.
marshmallow to Lollipop?

Hi, I just bought a brand new S5 and it has marshmallow already, I am trying to downgrade to 5.1.1 and it acts like the boot loader is locked, Ordin fails mid flash. How were you able to do it?

Hi! is your smartphone really a G900T?
IF it is so... It is pretty sure you download a firmware and it is incomplete.
Where do you download from?
Which version is it?
it is a G900T, I downloaded stock Lollipop 5.1.1 from T mobile

i have a Verizon s4 . its unlocked. i am using it in india . i cant find any lollipop firmware without Verizon carrier . how do i upgrade my device to 5.0 ?
I'm guessing you want t update to lolipop but can't because Verizon isn't in India? There's Muniz's rooted stock OF1 in the general section.

thank you for your help i am new to flashing . can you give me link please . i don't know what is munzi or of1 . . can i flash it with Odin ? is it safe like original roms?
are you rooted? If not could you tell me which build number your phone is currently at?
As for Muniz, he's a guy who works on rooting our galaxy s4 =)
the latest build for verizon galaxy s4 ends in OF1. it is Android Lolipop, 5.0.1
his instructions are here.
you'll need root to follow the directions.

from the looks of things , this looks risky . i would rather have a unbricked s4 without lollipop thanks for your help. is it possible to root s4 with iroot ?
It's not really that risky.
best way to root kitkat Verizon galaxy s4 is to use towelroot with NC5 build kernal
Verizon's Galaxy s4 is supposed to be unlocked by default, its just rooting is an option just in case you dont like the look of the s4's lolipop. if you want just complete current stock lolipop build OF1 you can download it here and use ODIN to flash, or just use Samsung kies software.
just so you know if you use the sammobile method or kies method to update to lolipop, you cannot go back down to kitkat. Muniz's method with root allows you to return to kitkat builds if you so desire.
by the way what happens when we flash a rom with carrier to a unlocked phone ?

wait a minute . the link you just send me . . isn't it a rom with Verizon carrier . my phone will remain unlocked if i flash it ?????
You do realize that Verizon phones are supposed to be GSM unlocked by default due to some agreement with FCC for their bands?
From here
Unlocking a Verizon phone
Even though Verizon uses CDMA instead of GSM, most of Big Red’s devices come with an unlocked SIM card slot. According to Verizon, its 4G LTE devices aren’t locked and, if you want to bring one of them to another carrier, there is no code needed to program the phone to play nice with it.
However, even though SIM-equipped Verizon phones can be used on AT&T, T-Mobile, or other GSM carriers, the phone will need to have roaming GSM radios in order to make phone calls and send texts in the United States. While most recent Verizon handsets will work just fine on American GSM bands, your mileage will vary when it comes to LTE support.
Even though Verizon doesn’t have an online unlock request, you can call 1-800-711-8300 and request a SIM unlock.

sorry for my lack of knowledge . i didn't know that . i bought it from my friend . i thought it was locked by verizon and he got it unlocked for Indian sims .
well, then the choice is yours, you can root your phone and use muniz's method to allow you the option of going back to kitkat if you desire, or just use normal methods like samsung kies to update normally, which will lock the bootloader so you can't downgrade.
As for me, I'm going to(try to) sleep. 3 AM here X(

thanks buddy you were very helpful . my last question what happens when we flash a rom with carrier to an unlocked phone .
well... if it was one of those international versions of the galaxy s4 like the GT-I9500, then you'd probably brick it by flashing a rom for a carrier version like the SCH-i545. or at the very least softbrick it.
I think unlocking phones is something more hard coded than the rom itself. cause, even if for example you have a att phone unlocked, it still has a att rom, and should be able to update the rom while using an att sim
though in your case, I have a feeling whoever "unlocked" your phone never bothered anything other than change the APN settings to that of whatever Indian carrier you were using.
your phone shoulnt have any problems with flashing an update via kies.
check your build number under settings> more> about phone. if they match any of the PDA here, you're on stock. using network signal info app in the play store can also tell you the build number (build ID) and bootloader.
though if your phone doesn't say "custom" when you boot it from power'ed off, that you're probably on a stock rom with no root
Hi, guys!
To all who runs AT&T M9 Firmware Locked to AT&T.
A lot of people can't run Nougat, bacause AT&T didn't want to share update signature key outside AT&T network. If you are not in US, you can't get Nougat update.
Does anyone have activated AT&T sim? Just flash your M9 by latest MM firmware. But before Make backup of your data, phone became clean!!!
What to do:
1. Flash file: 0PJAIMG_HIMA_UL_M60_SENSE70_ATT_MR_Cingular_US_3.38.502.41.zip
2. Use method 2 to grab OTA download link as shown here https://forum.xda-developers.com/sho...75&postcount=2
3. Post here result to share with others
Thanks for help!

Can you give me a quick tutorial? my phone is:
s-on
Unlocked
firmware: 2.11.502.21
If you have AT&T card, just use OTA update. I don't know all things how to update from Lollipop. Plase read Readme thread.
Anyone found the OTA url yet? I restored to stock, but it says no update available. RUU isn't an option since you can't go from 3.x to 4.x.
After giving up on rooting my AT&T phone well over a year ago this week I just found out rooting was available. Right now I am leaving AT&T and going over to T-mobile. I would like to get all the AT&T software off my phone since I will be with T-Mobile.
In searching for rooting ( I have not done it since my HTC One) I see rooting for 5.1 and 6.0. Right now my phone is running 7.0. Can you root with 7.0 running?
When flashing a Rom do I have to find ones that are specific to G925A?
Thanks for any help confirming this. I just do not want to brick this phone. First time I do things like this I want to make sure I have all my information correct.

So your just switching carriers to T-Mobile? And your using the same phone G925A?
It still has a locked bootloader so it's still not rootable. From what I can find you can root 6.0.1 on an older firmware with ENG boot firmware. But not for 7.0.
@ThatAngryGnome
i need G925AUCS7ERC1 7.0 root file
It's been forever since I've been here, missed this place. I am practically a noob now.
Here is my scenario:
I have a Verizon-branded S9+ / SM-G965U on the firmware/baseband G965USQ3BRK2. It is paid off, assured it is carrier unlocked and has also never been modified, pure stock. I'm looking to switch carriers from Verizon to another service. It's also my understanding that Verizon phones are a pain in the hiney and there may be issues with data, features, and other nags and warnings because a non-Verizon SIM is in use. Had an S5 that worked on other carriers but was a nightmare to configure.
Will I be condemned to a similar nightmare of nags and warnings, or will it rebrand it's self and allow me to receive OTA updates on the new carrier? Just not sure of what my options are, the search results yields conflicting information where some had to flash some firmware and others didn't.
Any recommendations would be appreciated.
I converted an unlocked Verizon S9+ to an unbranded, unlocked device, using it on T-Mobile and couldn't be happier with it. You have the option of flashing your own carrier's firmware or the factory unlocked, and it will improve your situation, no more SIM card notifications and all that.
P.S. I was in the same situation as you, used to be on here all the time but felt like a noob all over again. But a super helpful member here guided me through the process and it was completely painless, one quick flash with Odin and it was all good.

Welcome. Looks like there's some instructions here: https://forum.xda-developers.com/ga...icial-stock-firmware-thread-samsung-t3764479. However you will want to make sure you find the patched version of Odin to get past the fact that you are flashing a different firmware than is currently on the phone. And you will want to flash G965U or U1 firmware, that also has a 3 as the fifth number from the end, just as the firmware that's already on your phone.

Thanks for your help and for answering the questions.
Is there any benefit to flash U1 or would just U work?
Would the firmware downloaded using SamFirm work with that version of ODIN you linked?
Do I have to go through a rooting process and install TWRP prior to going ODIN on my phone? Or can I just go into download mode on my device, click yeah about a custom OS, then do the ODIN bit?

The U firmwares are those from carriers and the U1 is from the factory unlocked unbranded variant. so it's up to you if you want your carriers own firmware or just a generic Samsung version. If you need Wi-Fi calling and or volte, there might be a better chance of it working with your carriers firmware but the unlocked firmware does a good job with that as well, I have both of those features working perfectly with the U1 firmware and a T-Mobile SIM. Just make sure to use the CSC as opposed to HOME_CSC, so that your phone is fully wiped and configured for your sim card. I will say one advantage of the unlocked U1 firmware is free built-in caller ID ?
No rooting necessary, in fact it's not even possible on the US models, so just boot into Odin and flash the firmware using the patched version of Odin.
After i updated my s3 t827 with the original onu ui update, my tab is slower than a snail. I wanted to try custom roms before throwing it out of the window.
I use mobile internet with it and i do not want to lose that option with a custom rom.
Can u let me know if they killed this tanlet with the latest update or do i still have a light at the end of the tunnel if i use a custom rom?
Thanks
The 827 is the Verizon version. Basically you're locked into the Samsung/Verizon firmware. The device can't be rooted and you can't use custom roms.
How about the US Cellular or Turkish ROM? They are both T827 variants and I've seen where people have successfully flashed Verizon onto US Cellular units.
I use samsung t827 tablet Turkish rum but can this tablet be root and can be used as a phone ..?
