G900V firmware on my G900A phone

[oja60]

Hei all,

I bought my phone off ebay without realizing that there are different models for different markets. However inside the battery case the model number is SM-G900A. Since I off course wanted the latest android version that my wife has on her G900F I went about googling for a solution. After lots of tries and lots of failures, I eventually managed to root my phone with towelroot. I went on to flash a G900V firmware onto my phone (Don't ask why). Now I have a G900V baseband, bootloader and rom entirely. I then went on to update OTA to end up with Android 6.0.1 version only to realize that it cannot be rooted yet. I then went back to 5.0 in order to root and to install custom Twrp 3.0.2.2 recovery and unlock the bootloader to developer mode using sambootloader unlocker.

My question is this: How the h... was I able to transform my G900A to a G900V model to begin with. This is over a year ago, and I cannot remember how I went about it. What I do remember is that I used ODIN, with a G900V pit file and did a complete wipe checking repartition, nand erase all, phone efs clear, and bootloader update.

Now my follow up question is this: If it was possible to "transform" my G900A into G900V, would it be possible to "transform" it into a G900F model given that the hardware on the phone is identical ? I mean what is it that makes the phone a G900V, G900F, G900A model in the first place ?

Would it be possible to completely repartition the internal memory of the phone and flash a complete G900F package with bootloader, recovery, system, modems etc ?

If you are inclined to answer this with a short no, then please be so kind to explain why my phone now only accepts G900V firmware ?

You have done something very risky

Flashing another phone's PIT is a quick way to hardbrick (*i've done it before. what an argue at the service center!*)

Don't try to convert to a G900F... that's an even more different phone

Simply flash G900A PIT+FIRMWARE

Also, NEVER TOUCH any checkboxes in Odin like nand erase all and phone efs clear! Your phone will never work on cell signal again.

There is no way it should not accept ATT firmware because the signing key is in true ROM on Qualcomm S5s I believe

this is risky and dangerous i know all partitions except bootloaders can be flashed with flashfire on a bootloader unlocked phone but ive never heard of someone flashing bootloaders succesfully i wouldnt attempt it and agree with lightning i do remember g900a and g900v modems seem to be compatible but im dangerously curious can you remeber anything else oja60

No, not really. All I can remember is best described in the post above. I bought an S5 from ebay, probably delivered from asia somewhere. The back of the phone said G900A and I was curious as to why I couldn't get any OTA-updates. I the downloaded a G900V pit file and a stock G900V ROM from sammobile, and went at it. After installing it all the phone worked like a charm, so I could then go about rooting and unlocking the bootloader with the above mentioned method.

I have now gotten a hold of a G900F phone which I wanted to begin with. That means I could try the procedure again to see If it's possible to convert the now G900V phone into a G900F in the same way. I need to specify this however: We are not talking about running a G900F ROM on an unlocked G900V bootloader here (That's easy!). This is about converting the whole shambam. What I still haven't gotten an answer to is what makes a G900V a G900V and what makes the other models unique ?

Best regards
