AT&T and Verizon have locked bootloaders.
All the others are unlocked.
Also, make sure you get the quad core S4, it has the best custom rom support of all the S4 models.

MEans i can purchase sprint or tmobile ? & what about docomo ???
what do you mean by Quad core ??
how would i check that phone is quad core or not ?

I mean the I9505 model.
Don't they display the hardware info of the device?

Most i9505 ROMs don't support docomo variant. Slightly different hardware (even if it's still using same SoC).

Market is selling international version of popular smart phones .. but if you check model in bootloader you will find logo model numbers means i checked 1 phone .. market sale person was saying that mobile is international version but when i checked in recovery .. it was sprint !

[Q] Advice for buying n9005 note 3

i will be buying a n9005 note 3 tomorow & i was wondering if its ok to buy carrier branded n9005's such as SFR telecoms? the phones have been unlocked as such but will it be compatible to mods here? i also have a choice of the n9000 but i want a smartphone with the snapdragon 800
so if the carrier thing isnt a wise way to go...i might just opt for the Z1 or something...thank you

If you want to make root, look if the for de rom is mj1, mj3, if is mj7, you have to void knox and warranty, pres in phone *#1234#
no...what i meant to say was...is a n9005 with carrier logo as bootanimation before the samsung one eligible to the same sort of modding as a unlocked n9005? also this carrier flashing n9005 was probably unlocked because any sim works

Flashing international Firmware

Hello everyone,
yesterday, a family member gifted me an s7 from the USA (SM-G930P). He bought the phone off SPRINT as a SPRINT unlocked version, and, of course, because I live in Europe and want to use the phone with a European SIM card I have the "hands free activation" mark that is sitting on the top left edge of the display. I also noticed some changes, for example the "mobile data" toggle is nowhere to be found and also I don't have the options to choose the network mode (2G/3G/4G). I love the phone and I also would like to keep using it, I only need some answers from you guys.
My first question is, if the phone will actually let me use 4G network with my European SIM card, or will I be limited to 3G?
My second question is, If I can flash an international firmware for another carrier and another country on the phone, and if so, will I have the advantages of that firmware, like the Mobile Data Toggle??
Thank you very much for your answers.
If you install the 'Network' app you might be able to change the network type.
In general you should be able to use an unlocked P variant with a foreign SIM but you may have to activate with a Sprint SIM first.
You can't flash the international version since it's Exynos and the P version is Qualcomm CPU.
I am not sure if this model has Samsung region lock which is another thing to consider.
If I was you I would try to flash the U firmware (US unlocked) as it has the most support for international 4G bands among the Qualcomm US models. It also doesn't have all of the Sprint bloatware on it.

Thank you for your reply. I am currently using the European Sim from my carrier and I have no problems with it. I managed to get rid of the Bloatware by using Package Disabler Pro, but it still sits there somewhere on my phone. So far, the phone is working very well and other than the bloat sitting on my memory and the lack of LTE, I have no complaints.
Can you tell me if someone has tried to flash the U firmware on a P model with success?

Could you tell me how you did it, or link me a guide??
I had bought an unlocked Sprint galaxy S7 (930P) off ebay which died on me. Got it repaired from the service center and they sent me a locked device instead. The phone is currently on Software Version - G930PVPS4BQC1 and the hardware revision is Rev 0.6. I'll be using the phone in India and have a few questions.
1. I need to get this SIM unlocked from a service online. Does anyone know of a reliable place to do so?
2. If I flash the U Rom on it after unlocking it, will I lose the unlock? (I don't mind downgrading from Nougat to Marshmallow)
3. Should I unlock first then flash the ROM or flash the ROM first and then try to get it unlocked?
4. Will flashing the ROM directly unlock the phone itself?
Please advise.
...
you could try gsm zambia to unlock your phone it works i tried it myself a few days ago, also after my phone got unlocked i flash the U firmware/rom and the unlocked remained. so you should unlock your device first then flash the U firmware :good:
PS. if you one nougat better to downgrade if you can do marshmallow so when you wont have any issues flashing to U firmware. :cool

UAE S8 to Canada S8 possible?

So I purchased this phone off of Ebay, only thing it said was International version. Once I got the phone I found it was a UAE phone.
Is there a way to flash a different locale to it? Things like Android Pay don't work, and I can't get into the Samsung Beta because the SIM and Phone region do not match.
As far as I know, Canada gets the International version of the CPU.

This is the wrong section to be posting this in. Should've been in questions section. But Canada has the snapdragon processor and the international has the exynos processor. Snapdragon has locked bootloader and exynos has unlocked bootloader. There is a thread with steps on how to flash different carrier firmware
If anything you should be excited. I'm Canadian and stuck on the romless Snapdragon version.

I had a UAE S6 and it worked fine in Canada. Got all the updates from Samsung on the UAE schedule (aka sooner than Canada)

Firmware change question

Hey guys,
I am currently on Samsung S10+ in Canada, which has a single SIM and unlocked. As I need a dual SIM now, I am planning to sell it off and get an international model with dual sim.
My question is: Do I need to change the new phone's firmware to Canada to get OTA official updates? Can it be changed?
Thanks!
The answer is no. You cannot flash the Canadian firmware on the international version. For starters, the international version is Exynos chip. Also, Samsung Pay will not work in Canada with the international version.

Thanks so much for the reply! So what about updates? Will I still be able to get them without changing the Firmware (as you mentioned I can't anyways)? Yes, heard about Samsung Pay, but I don't use it much so that should be ok. But I wish we had an option for Dual SIMS here in Canada
Thanks again!
You will not be able to get Canadian OTA updates. You will have to download international firmware releases compatible with your device and flash them.

You will get updates normally but not same as the Canidian model. so if local s10 get update dosent me you will and same way other way. When ur model code has an update you will receive it ... so dont worry u can buy and you will get OTA normally ... or you can flash other FW on it but i dont know about snap and exn .. I always flash my Brazilian s10+ with eurpian verison and leave HOME CSC so SamsungPay still brazilian.
