Questions About Basebands, Mobile Networks and Unlocked Devices - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I have a few concerns to address. I recently bought the Galaxy i9505 (or in my case, the Sprint SPH-L720T version). The device comes unlocked with stock firmware/software, Lollipop 5.0.1 baseband OH2.
Now I will try to make this as clear as possible. We don't have the Sprint network here, I'm on Vodafone. I just flashed an official ROM from Sammobile with a different baseband version (this one) because I can't find the version that my phone came pre-installed with. I upgraded to address the StageFright and widgets app draw issue that was on the stock ROM.
Now my question is: by flashing a different baseband version, will I lose the ability to have an unlocked device and incur roaming charges on my network, or is the unlocked to work on multiple networks feature on a firmware level so I don't have to worry about it?
Thanks.

You will lose your domestic/international unlock of you upgrade the Baseband unless it was actually unlocked by Sprint.

Yeah, I kinda figured that would be the case. Good thing I made a backup.
I suppose you wouldn't know where I can get a StageFright Patch for the OH2 version by any chance?

[Q] Need some information about I9502 (Samsung galaxy S4 Dual)

I had purchased an I9502 through olx.in, last week.
Second hand.
Due to rare users, there is no dedicated thread on XDA for my device
Now, many questions arises.
I had updated to official lollipop (5.0.1), by SAMMOBILE's official ROM. After upgrading, my second SIM cant connect to network. So I revert back it to KK (4.4.2). Still the problem persists !!!!! . I couldn't use it as a dual sim phone Is PDA and CSC version is important while flashing? or we could install any PDA/CSC rom version on samsung phones? I don't know the original ROM so, I had downloaded all firmwares available at sammobile and tested. only 2 of them managed to register my SIM(first) on network. Is it a hardware issue? or by a wrong ROM ? anyway now my mobile admitted at hospital and specialized doctors have been studying his disease
Is there anyone using dual SIM without any errors?
The PDA and CSC are vital to ensure you get the right regional variant for your device. The only exception is if the phone is unlocked for use on another carrier, in which case you can use a ROM from any region. Where you have the dual SIM version however, you only have one region available to you, but with multiple Android versions. The firmware here is the latest for your device. Do a factory reset before flashing through Odin.
I am totally disappointed.
My technician said that it had lost IMEI !

What will I do?
Is there anyway to recover its IMEI?
I had followed all guidelines available through search.
But, I couldn't...
Please help me on this....
Flash just the modem through Odin. You can extract it from the firmware download. Sometimes the modem needs to be flashed twice before everything functions correctly.
Other than that, I'm not aware of anything else software-wise that can be done. You'll need to take the phone to Samsung themselves and have them look at it.

How to check which Samsung SM-G935F (S7 Edge) variant I have?

I am trying to register my phone onto Samsung's website but there are a ridiculous amount of variants of the SM-G935F.
About > Settings only appears to show "SM-G935F".
Any ideas?

Wrong.
My 'Baseband version' is G935FXXU1APB2.
That is not on that Samsung list - probably because it's not asking for my baseband version...
EDIT: The SamMobile Device Info app on the Play Store found it for me.
I don't know exactly where you will find this information, but they are related to the version of software installed by the carrier - for example, the EVR variants are supplied by and locked to EE, the O2x variants are supplied by and locked to O2.
Mine came from the Carphone Warehouse - they tend to ship phones that do NOT have the carriers own software, and to confirm this, mine is the top variant in the list (ABTU). I registered my phone online using my phone, and it somehow auto detected the correct variant.

How Do You Find Bootloader Version?

How do you check to see what version bootloader you have? I have unlocked my bootloader on my Note 3 and am running OF1/5.0. Ready to install TWRP and new ROM. But, not sure if I have a 4.3 or 4.4 bootloader and can't seem to find a simple answer and how to confirm.

This is what you'll get... In my case.. NC4 bootloader (unlocked) and OF1 based OS (Jasmine ROM)

Thank you for the recommendation. I dig the app, though I still don't know which bootloader I have going by the 4.3/4.4 scale. I'm assuming by now I have the most current one, which ever one that is, because I installed the latest TWRP and am running CM13 with no issues thus far.

The last 3 digits represent the OS/bootloader/firmware versions. In my case, bootloader is NC4 which is 4.4.2, my baseband (modem) is NK1 which is 4.4.4 and the ROM base is OF1 which is 5.0

Ah, now that makes sense. Thank you for the explanation.

Unable to revert to stock rom

I have an unlocked Galaxy S8. I flashed it with the stock Sprint rom to get Sprint visual voicemail and wifi calling features. Doing so changed the model of my phone from SM-G950U1 to SM-G950U. Now, I am unable to flash back to the stock rom because Odin says the model number doesn't match. What can I do to revert back to the stock rom for the unlocked S8 with region code XAA? All help is appreciated.

I recently reverted back from T-Mobile firmware to unlocked S8 as it used to be. You need to use custom Odin, not the regular one.
Do the section where is says "Flashing Unlocked Firmware"

I don't know which ROM to install for my phone, because CSC and Baseband and PDA are different. It cannot be updated by OTA in settings. My android right now is 8.0.
