Hi all
I am newbie to the android world, i was gifted an at&t. S4 i337 model for new year. It was purchased as an unlocked device so it can work in india, but it wasnt,when i load my indian sim ,s4 always prompts with simunlock code.
I read lot of the xda thread to overcome this , intially s4 was in 4.2.2 MF3 build, i was able to root the device but i wasnt able to unlock for international band. So i updated to 4.3 using the thread "http://forum.xda-developers.com/showthread.php?t=2573080" since most of the reviews had positive feedback for unlocking. My software version got updated to 4.3 mk2 build But to my notice after this s4 loads with custom unlocked padlock symbol and rooting dosent work, it always fails when i run the supersu app in disabling knox step.
I followed every step as it said in the thread ,but failed every single time, the thread says it will work only with stock rom, since it boots with custom is this the reason for failure. How can i recover from this. Ur help will be appreciated, i have my s4 unused for past 1 month because of this.
Thanks

Hey guys,
I've been trying to unlock my phone for a few days now. Long story short, I moved from Canada to Japan and now I want to unlock my S3 to use a Japanese SIM.
I bought an unlock code from eBay. I was previous running cyanogenmod but then I was told that rooting will cause issues, so I unrooted my phone after an unsuccessful SIM unlock attempt. (wiped the phone, installed stock TW)
Even after unrooting I still had issues, and was given directions for the Service mode. That did not work either. I have tried many different methods and troubleshooting tips and nothing seems to have worked.
Here are some screenshots of the debug mode, my phone details, and a simple root checker app I installed.

My first thoughts are that since its from ebay it might not be a real unlock code.
I have had a lot of difficulty unlocking my GS3, as well. I actually got the codes from ATT, my carrier. I've tried 4 times, each unsuccessful. It says that after 5 failed attempts, the phone is forever locked to ATT, so I'm afraid to try that last 5th time. I was wondering if you could root, and then unlock more reliably. Is that possible?
Root makes no difference, you probably don't have an i9300 if you are on ATT.
I just unlocked my s5 from att to switch to tmobile. it stated the unlock was successful. afterwards it said that sim not allowed mm#3. it is completely stock and updated to lollipop. i do not know how to use odin or any of that so would need some help and insight on how to fix the problem. really would like soon so i can use my phone again and my imei is clean
Hi, thank you for using XDA Assist. The best place to get help is here,http://forum.xda-developers.com/tmobile-galaxy-s5/help. I'm going to ask that your post be moved there.
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
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

Hello everyone,
I have tried to look for an answer to my question with no luck. I have an unlocked t-mobile galaxy S5 unrooted with stock ROM and I am with At&t. I need to use wifi calling and therefore I was wondering if I can root then flash a stock AT&T ROM on my device, and what tools I should use. I mean are ROMs cross compatible. I would really appreciate your advice on this.
Thanks
It's a shame no one has an answer for this.
I'm looking for information on this, as well.
I have a SM-G900T (bootloader unlocked). I'm wondering if I can get it to be "stock" (without the yellow Knox warning on boot) and not have the T-Mobile startup animation or apps.
