[Q] Rooting Verizon S4 on AT&T Network - Verizon Samsung Galaxy S 4

Hi,
I have a Verizon S4 (SCH-1545) MK2 running Android 4.3. It is rooted and I flashed Hyperdrive 13 via SafeStrap. Then, I switched carriers to AT&T, but I am using the same Verizon S4. I am still running HD13.
I was wondering if I can upgrade to HD 16. I have to upgrade my base to NC5 KitKat 4.4.2 before I can flash HD16. Will me switching carriers have any effect on how I upgrade/root/flash HD16 and all roms in the future?
Thanks

Verizon uses CDMA and AT&T uses GSM, you may be able to get Voice working, but I highly doubt you will get an LTE connection since they are different frequencies.

Recently, they unlocked one of the bands of LTE to allow traffic in the Verizon S4. If you check the bands on phonescoops, it will show that is is compatible with one of the LTE bands. In theory, it should get LTE in the major cities that have that band. However, Verizon likes to be stupid and lock their devices.

You will be able to get GSM working on your S4 with EDGE or even 3G data, but LTE is unlikely. Voice and SMS will work fine. You will have to get the APN settings for AT&T and set it up in your phone.

[Q] Unlocked AT&T S5 on T-Mobile

I recently unlocked and rooted my AT&T Galaxy S5 to use on T-Mobile network. However I still have AT&T firmware on the phone, and I'd really like to flash cyanogenmod, or at at the very least stock T-Mobile. Is there any way to do this? Thanks in advance!

Don't know if there is a Cyogenmod available for your model (SM-G900A) but there is an AllianceRom which is built off the T-mobile SM-G900T firmware which will work on the AT&T S5. However, since that version of the S5 has a locked bootloader you will need to use Safestrap Recovery instead of TWRP. You might want to look among the threads in the AT&T S5 area of this forum for more information and maybe ask your question there. I brought my unlocked AT&T S5 over to T-mobile and used it for a few months before getting a T-mobile S5. AT&T stock s5 firmware worked fine. I also did try out AllianceRom on that phone briefly but stick with stock. I don't think rom slots ever got fixed on Safestrap so only the stock rom slot could be used for flashing which is one of the reasons I chose to stick with stock on that phone.

[Q] Moving i545 to Tmobile

I'm trying to flash a TMobile ROM on the i545 to use on TMobile. I have Insane 4.4.4 Hybrid v6 working, but the cell radio is not. I've tried flashing modules (which made the wifi work - I assume that is the module's only function). I have flashed 2 different i545 KK kernels to no effect either. I have it flashed in rom slot 1, should I be overwriting the stock rom slot? I'm running the latest NG6 (came with it updated), but can downgrade to NC5 from my understanding, if needed. I'm not sure what I'm missing to get it working, as I know others have. Thanks.
You don't need to flash a T-mobile ROM, just insert the T-mobile SIM and set the APN.
Edit: just to be clear - the i545 will work on T-mobile, but only on bands that VZ and T-mo have in common.
Flashing some other carrier's ROM won't change what frequencies are supported by the radio hardware.

Thanks. I know this, but I need the wifi calling feature that is only in tmobile ROMs.

[Q] Any T-Mobile S5 specific issues? Can it use S900F ROMs?

Hi all, I'm considering getting the S5, but where I live only the T-Mobile version is still available (international version is sold out). Are there any limitation/issue with the S900T? Can we just use an international ROM (for the S900F) and have it run flawlessly like the international version? Thanks in advance.

I use the G900T on AT&T using Omega Rom (a G900F Rom) and have no issues. I'm not sure what country you're in but the G900T has all the LTE bands the G900A has and a few more.
The G900T does not have a locked bootloader like the G900A does. It's a great way to go if you need a GSM phone in the U.S.

flash unlocked Verizon s4 ?

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(

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

Convert Verizon S5 to full T-mobile S5

I have a Galaxy S5 that was on the Verizon network. I now have it on the T-Mobile network with a T-Mobile sim but I still have all the Verizon crud.
I have it rooted and the bootloader unlocked. Can I just flash any T-Mobile stock/rooted rom and have it be a full T-Mobile phone?
I've rooted several Sprint & T-Mobile phone but have never done a carrier change. Currently it is on Verizon PB1 Lollipop.
Thanks to all.

I'm in the same boat.

Did you ever get it working?
No. It wasn't my phone but a friends. His main compliant was that it did not do location searches correct and I fixed that by adding the T-Mobile info. He said he would just leave the rest alone.
doesnt verizon lock its bootloaders? the device is different, it's not a G900T
slight success
i have flashed my Verizon s5 to the T-mobile based Twisted lollipop ROM.
http://forum.xda-developers.com/tmo.../rom-twi5ted-lollipop-5-0-v1-deviant-t3037766
i used this process because i had a stock 6.1 Verizon ROM which was crap.
http://forum.xda-developers.com/ver...t/rd-unlocking-galaxys-s5-bootloader-t3337909
jrkruse, guide is really helpful along with the link above.
However, i have problems with the lock screen not loading and when i turn the brightness all the way down my screen flickers with a yellow hue until i turn up the brightness. I am lead to believe that the screen flickering yellow is a hardware problem with the screen. Nevertheless, i am trying to move to a stock T-mobile Rom now even though i don't have a t-mobile kernel.
I have verizon s5 I'm attempting to do the same too... If only we could change the baseband from verizon to tmobile? I have cid 15 chip and have done the unlock. Could there be a way?

Flash Verizon S5 to T-Mobile
I was able to get it working! I have unlocked my Verizon S5 boot loader following the directions from the Verizon S5 page under XDA. I then flashed the sm-t900 pg2 firmware with TWRP. Everything seems working fine.
