Where did you find the file? Do you mean you flashed the tar.md5 to the phone and it works? I'm suffering the same issue. Can't get the S5 to work with an ATT Straight Talk sim even though it's an ATT phone, clean IMEI and the ATT card works in an S4.

Firmware flashing

Is it possible to flash the firmware of another carrier and have the phone work with said carrier? Just curious.

That's not really how it works.
Different variations have support for different frequencies, you can't change that.
Also, if it's SIM locked, you'll still need to SIM unlock it.

T-Mobile stock firmware on SM-G920T factory unlocked version

I recently purchased the G920T factory unlocked version on eBay, is it safe to Odin any T-Mobile stock firmware, any info will be appreciated, thanks in advance.
Once you above a certain firmware you can't go back. What firmware you currently on?
It is currently on G920TUEU3COK1 can I Odin to the latest T-Mobile G920TUVS3DOJC I understand that I can't go back but is it safe and will it function normally, thanks for the reply.
i have this same question because from what ive read 3COK1 is for Cellular South (aka C Spire). while the 3DOJC is for Tmobile, both under the G920t firmware. are you also on tmobile network with this phone?
What are the benefits of flashing T-Mobile firmware on the USA factory unlocked phone? I have this phone on T-Mobile and wifi calling works. I also get great reception. I assume this phone will get Marshmallow months before T-Mobile releases their build

Does this firmware that the device came with (G920TUEU3COK1) have any carrier branding or logos anywhere? Id like to switch if it doesn't have carrier branding

Are you getting LTE on it.
So I flashed the C Spire firmware and it asked for an unlock code. I flashed back to the original tmobile firmware and it is still locked although it was unlocked before, but the device unlock app says its ineligible for unlock now.
Anybody else encountered this?
Call t mobile customer service and ask them. They can adjust their servers and then the unlock app will work.

I'm sorry I misread that this a different model. I'd try to contact the user stifilz to unlock.

Were you able to get it unlocked? I plan on doing the same, flashing the unbranded to my t-mobile that is currently unlocked.

I'd advise that you dont.
To unlock it I had to flash back to the original tmobile rom. From the tmobile rom, the device unlock app failed in different ways.
After i called tmobile over and over I got it unlocked (like 2 hours of calling).
Hurts my heart to see all the tmobile bloat, especially when i dont even live in the US, but at least my phone works

Thank you, I guess I'll just sell this one and buy an international unlocked, glad to hear you got your phone working.
Anyone successfully updated this G920TUEU3COK1 US factory unlocked version to marshmallow? I have Samsung Pay, wifi calling, etc. all enabled on mine and would like to update, but also keep the unlocked non-bloated firmware.

Which method did you use to update the G920TUEU3COK1 US factory unlocked version? Does using the Tmo firmware risk un-unlocking the phone?

Quick Question 910A At&T Phone - Prepare for T-Mobile Rom - Unlocked Already!

My friend has a 910A At*T Note 4 - I unlocked it and her data, calls, pics, texts all work GREAT!
Now what else should I do to prepare it to get a T-Mobile Rom, as she is with T-Mobile and wants root and a custom rom on it
Thanks in advance - tried searching nothing much came up on this Topic.
N910A has a locked bootloader you cannot flash ROMS on it.

To my knowledge there is no root nor anyway to unlock the bootloader.
The phone is locked down.
That is why people who wanted root bought the N910T from tmobile and use it on AT&T.
Sorry to burst your bubble.

I unlocked my AT&T Note 4 and am trying to use it with T-Mobile but it won't register on their network. I can't even make calls, I can only get numbers off of the sim card. Any ideas on what I could do?

I have outright bought my phone from AT&T and is now unlocked

Can I change the rom on the phone if I wanted to without being tied to AT&T? can I download something via odin3 to make it any other ROM other than AT&T? I hope I have NOT confused the issue.
Many thanks for taking the time to answer.

No. You are carrier unlocked so you can use another carriers sim. You are not bootloader unlocked, so no custom recovery or ROMs.

[Sprint] Unlock Bootloader?

I know the Sprint bootloader is locked, but does anyone know if there will be a way to work around this?
I have seen some threads on a trick to unlock the Verizon bootloader even though it also comes locked- would this work for Sprint? Thanks
UPDATE: What is the Pixel version of MSM/ODIN? I know how to get to EDL mode on it, but from there how would you go about flashing a different firmware to potentially get around the bootloader? Anyone know?

Why didn't you activate the eSIM option? Went smooth and easy for me on my unlocked Google version.

Mine is not the unlocked version and I read a few threads saying it isn't grayed out if you don't activate the sim first, but alas it was still locked.
Anyone know if the sprint version is unlocked for other carriers
