Is it safe to upgrade firmware targeted for one Galaxy S10+ device to another device?
Assuming both phones are either running Snapdragon or both phones are running Exynos.
Example:
- buy SM-G9750/DS (China/Hong Kong version)
- flash firmware from SM-G975U1 (US Unlocked version)
Will this be safe? What is the procedure? Has anyone attempted it?
Will I lose Dual SIM capability?
What are the potential benefits of doing so?
Will this also enable more bands (which are not enabled on China/Hong Kong version of the phone? example band 66 and band 71?).
Is there other way to enable those bands (CDMATool does not show those bands in selection).
Bands are hardware, not firmware. Flashing different firmware won't enable more bands. Flashing different firmware won't get you anything I'm afraid. They all effectively share the same firmware. All you'll do its cause potential issues.
I know the Exynos dual SIM variants share thw same firmware as the single SIM Exynos variants. But I'm not sure about the G9750/DS and G975U1 .

If you flash a different firmware, can it unlock different bands based on which firmware you flashed?
For example, I plan on buying a verizon S7E, if I flash it to either the u firmware or t-mobile firmware, will it unlock band 12?
I'm seeing conflicting information on how to flash our phones with official software and have a few questions:
Where is the carrier-free US S8 (not plus) variant firmware? I've searched, what even is the CSC for it? XAS, TMK? XAA?
I found a thread that seems to have the EXACT process for flashing any carrier firmware, it says to download the G950/G955W firmwares, which ones? There's some for Bell, Fido, etc. The op failed to provide links.
Has anyone actually successfully debloated their US carrier S8 with a non-carrier firmware, a firmware simular to what we had on the G930U? If so, could you post your EXACT process, down to the very download links you used?
I'm using a T-Mobile US Galaxy S8, and my friend has a Sprint Galaxy S8+, we both want the carrier-free firmwares flashed, but things seem to have changed a lot in the many years since we've flashed phones (the last phone I used Odin with was the Note II!)
Thank you
I'm not too knowledgeable when it comes to the US variant of the S8, but I can tell you this much, the SM-G950W is the canadian model it seems, and XAC is the unbranded non carrier firmware for that model.
Hello,
Is it possible to convert G900A (AT&T) firmware to SM-G900W8 VMC Canada (Virgin Mobile) firmware?
Thanks!
no. different bands. odin will not allow you to flash the firmwares
the G900A is bootloader locked, not o good variant to flash roms/root
but if phone is sim unlocked it should work on any gsm netwrork.
as for canadian fw, why would you want it, all fw are basically the same except the bloatware that is added and/or specific carrier apps for some added user functionality.
the radio/modem might come into play depending on the variant/carrier, but should be ok from att to use in canada
What's the differnce of International Version and US Version?
Both support's VoLTE?
And can i use on South Korea?

Us versions are based on snapdragon processor, International is exynos, also they both operate on different radio frequencies, so I can't take my international device over to us and put a us sim in even if it's unlocked to all networks. VoLTE is carrier specific and if you wish to use it you will need to flash that specific carriers branded firmware if it's available for your variant. South Korea has it's own variant, you can't use a Korean sim in a us or international device, that's as far as I'm aware, someone can correct me if I'm wrong.
I bought s8 (G950N-Exynos-singled sim) from south korea though i live in india. Here voLTE wasn't working before, then i flashed a custom rom hadesrom one ui by corsicanu. Now voLTE works almost fine.
But the network service of my device is very poor than indian s8 (i compared it with indian s8). I was wondering if i can flash the bootloader and modem of indian s8(G950FD) via odin .
But the problems are 1. my phone is singled sim, 2. there are no such indian s8 firmware of android 9 on sammobile.com.
What if i flash the bl and cp of G950F ?

voLTE is a carrier specific service. if it wasnt working on your previous ROM and is currently working on the new one, then the dev baked in the goodness of voLTE on your ROM where it was absent prior in the previous ROM.
Anyways, as far as what will happen if you flash the G950F firmware, it will boot and then the phone will think its a G950F. Thats it. Exynos processor S8's can accept the F firmware

use this version of Odin. Teh linked page described why your phone is failing the flash. Its tripping up on a 255 error
i had to use this on my A8 when flashing the UK firmware on it since it was a UAE market phone
