[Q] Need Expert Answer for Noob Questions

Dear All
I am from UAE & bought Galaxy Tab yesterday. I have inserted my SIM and it is working fine but need to jump into upgrading firmware business
I have read many threads but got confused with the information. Can some expert please answer following :-
1. How can i check that my TAB is Factory Unlocked? I have checked using that *# code and it says all locks are off.
2. If my tab shows me that all locks are off, does this mean it will not get Locked if i upgrade the firmware?
3. I have currently
PDA: P1000JPJJ1
PHONE: P1000JXJJ1
CSC: P1000OJPJJ3
Can you please advice which version from samfirmwares.com i need to take for upgrading it? Currently its Arabic but i dont need Arabic. Can i install Euro version? If yes which one please?
3. Can i root & unlock all available firmwares? Should i root after upgrading firmware or before upgrading?
4. I was an iPhone user. So curious if firmware upgrade will also upgrade baseband and phone can be locked?

I dont have a tab (I may get one)
1) put a sim card in from another carrier
2) should do
3) use the samsung update utility
4) like iOS updates may block the root exploit but if it is factory unlocked then it shouldn't lock the tab
5) there may be baseband updates (my htc wildfire has had 2) and they didn't lock it

Thanks for your reply but one question is Unasnwered. How to ensure that my Tablet is Factory Unlocked before i upgrade?
Putting another sim will not confirm that it is Factory Unlocked as it can be unlocked using methods in this forum and then any SIM can be inserted. Same concept like iPhone... Right?

By factory unlocked do you mean so you flash stuff on it and do upgrades? If so you ll have to look at a rooting guide, they dont.come unlocked like that.
If its sim unlock puttin an other sim will tell you

I understand that to flash firmware and custom rom, i need to root it.
By factory unlock, i mean network unlock. It works with all SIMs now. I dont know if it is Network unlock from Factory or using methods described in these forums.
So concern is that if i upgrade to new or Euro firmware now, will is become network unlock again? If yes can i unlock it again on latest firmware?

Upgrading firmwares wont lock it if its unlocked. It will be in the same lock condition as it was before the update

Custom ROMs for SIM unlocked SPH-L720

Hi,
I have recently sim unlocked my SPH-L720 that means my Sprint Galaxy S4 is now working on T-Mobile sim. In order to do this I had to downgrade my baseband to MVC. Earlier I had NAE baseband. I think I read somewhere that I cannot upgrade my baseband version which will revert SIM unlock.
I want to install custom ROMs on my unlocked Sprint mobile now. Can someone please tell me how many custom ROMs can I install on my modified device? I am very much inclined towards installing Carbon Rom but not sure whether it will break away sim unlock feature. Here is the link to the post. http://forum.xda-developers.com/nexus-4/orig-development/rom-carbonrom-kitkat-t2630336
Please guide..

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

You have a snapdragon version that has a locked bootloader, there is no current standalone root method, if you have the latest bootloader installed then the mentioned methods you've used won't work as they haven't patched it yet. Blame the network providers for all this.

As a side note more than likely you will convert your model to a U model instead of a w
