Question Flashing Another Country/Region's Firmware?

[nsfxpython]

One UI 5/Android 13 still hasn't hit my US (SM-A536U) phone yet. I'm leaning towards this being a no, but would it be possible to download the European firmware for Android 13 for the A53 and use it on my US phone? I'm hesitant because the European variant is SM-A536B and mine is SM-A536U. That would prevent this from working right (them having different model numbers)? I just want verification.

If this is possible, I would just download the Europe firmware from Sammobile and flash through Odin, right? Does the device need an unlocked bootloader? Can't do that on a US variant if so...might be out of luck. Anyways, thoughts?

**And I don't wanna hear crap about "just wait for the OTA update to hit your phone", I hate how there's no set date for when the OTA update will get to my phone (one of the only things I miss about owning an iPhone, everyone got the new update on the same day).**

I think it should work - they seem only to differ in network coverage, yours supports more bands:

Well, you know the usual disclaimer like bricking, dead kittens and WW3, right?

Oh of course! If this fails the world falls into total chaos.

You're talking about the network bands, right? I'd imagine that shouldn't have much of an impact when it comes down to firmware. I wonder if I'd see a decrease in network performance? Hmm things to consider. Thanks for the insight!

Anyone else have anything to add? I think I'm gonna try flashing later today with the European firmware.

You don't need unlocked bootloader and you don't lose warranty as long as you flash original firmware with Odin. However i'm not sure that you would be successful in flashing EUX firmware on A536U model, try not to brick your phone. It probably wont work anyway and wont let you go trough with flashing in Odin as it's different model.

When comparing the models, they seem to be nearly identical in terms of specs. Like mentioned above, the only difference comes from the network bands. I guess the US variant has more bands to it than the European variant. Now I'm second guessing lol. I have the firmware downloaded, just backing up my phone in case things go awry.

Yes, but it's not that simple. You would probably have to change CSC first, i think SamKey tool is used for that, if hardware is the same maybe it's a possibility.

Even at SamKey US model isn't supported yet. US/Verizon model uses different 4G and 5G band frequencies, you could do a lot more harm and i'm pretty sure phone wouldn't work.

Noted! Thanks for all the info.

I guess it would be safer to wait for the official OTA. At the end of the day I still want a working phone. Really not a fan of how Samsung releases its updates. Appreciate the help!

It would be best to wait, also i can tell you there's not much difference in OneUi 5. Visually is pretty much the same.

Would it be possible to do the same thing for the exynos model. I have a a536w model.

All the A53 models use the same Exynos processor.

Hi Guys,

Would a conversion from a SM-A536E to SM-A536B be possible?

Yes go for it!

 

[PlutoDelic]

Yes go for it!

So Odin failed with re-partitioning part. The SM-A536E i have is a Dual Sim with 8GB RAM. Is that the issue, or do we use a patched odin in this case?

Try using a patched Odin.

Try using a patched Odin.

Pardon for asking but has this been done before? Dont wanna be the guinea pig.

Yes many people have done it.

Just tried the Patched Odin as well and too it's failing. Could be the 8GB RAM being different somehow?

Hesitant to try the PIT path.
