Flashing international ROMS

Since the galaxy s6 edge has the exynos 7420 cpu does that mean international roms will work on US carriers? just have to change the APNs?

I have been wondering the same thing. Have you gotten any further with this?
I'm in South America and would like to flash an INT ROM hoping to get LTE working here. LTE Band where I am right now is 1900 mhz. Would flashing an INT ROM "unlock" the phone for that? Are there other "consequences" that one should be aware of when flashing an official International ROM? Any comment on this is appreciated :good:

no i haven't found any information on it sadly :/

Im searching information about too. I tried install some 925F roms then flash 925p kernels but no luck. GPS not working, data/voice not working, even no mobile operator setting in setup.

You would need more than just download and flash!!! You need to port libs, xmls, framework, apps etc to make it compatible with Sprint

Anyway of getting a sprint compatability zip?

Thanks for the info. In my case I don't need to make it compatible with Sprint since I'm in South America. Any suggestions on how to flash an official International G925 Rom?

I think that will happens only when somebody write unified kernel for F/I/*/*/*/and P version of this phone. I researched this and found that noone from kernel makers want not do this. In nearby thread one programmer offer to try modified bootloader for 925p (to be able rollback to 5.0.2). He can't even find testers(. No one want brick their phones.

Not true..... People have been testing bootloaders. Still more work done to be done to it. There have been about 5 testers

S6 G920F roms on S6 G920P?
Dear users
I would like to have S6 International roms on my S6 Sprint but I can't,
is there a compatibility for sprint file to fix the other touch screen and other processor (exynos and snapdragon)?
Please, can anyone reply if you know it?
PS: Sorry for my English, it's not good.

Unlocked SM-G955U

Last year's S7/S7edge had a different model number for each carrier (G935A/T/V/P/R4), but this year they all seem to be using the 955U model with different CSCs for each carrier.
I noticed on SamMobile there's an unbranded firmware available for the G955U with the XAS CSC, what CSC is that? Generic?
The reason I ask this is that because these US variant phones get imported to Pakistan and some people buy them since they're cheaper than the officially sold G955F models here, so if a G955U gets imported here which for example was previously used on T-Mobile in the USA, if one flashes the XAS ROM, will it basically be an unbranded Snapdragon 835 S8+ or is removing the carriers CSC not possible?
All replies will be appreciated.
Cheers

The U version is locked and not able to root. It's used by all USA carriers and they probably made it locked down due to Samsung pay. At some point a root crack will surface but it probably won't be stable

I don't need root though.
Just the possibility of flashing an unbranded ROM with no bloat, something that won't be used with US carriers.

You cannot flash firmware without rooting on this device. That's my point. When you try flashing in Odin, nothing happens. That's why you cannot root or even flash things. Got it? You need root in this case.

I think we are after the same thing; xas is sprint from my understanding. xaa should be the "unlocked" carrier neutral you are looking for. There is a thread in the s8 forum where some people had success flashing parts of the Canadian firmware then refreshing parts of us firmware they had quasi obtained this but I have yet to try
https://forum.xda-developers.com/galaxy-s8/how-to/rd-carrier-switch-root-snapdragon-t3597473

I read somewhere that only G955f models can change CSC firmware using Odin.
G955U models won't be able to... I could be wrong...
Then again, we won't really know until someone buys the U model and tries it out for themselves.

What did you find out? I'll try it with mine but I need help. I am by no means a schooled veteran in the world of command lines and tech talk but I can follow direction. I've managed to unbrick a couple LGLS 675 and bypass frp (for myself) a couple hundred times. I'll post a screen shot of my about phone if you guys are interested.

im using a 955f (so could be different on your phone), but just turn the phone around, on mine the S/N stands printed on the bottom of the backside, you can slightly see it ->here<-
and also I'm really not sure about that, but i believe some Serial/IMEI/whatever-numbers do stand in download mode
EDIT: By what i've found google'in, on the 955U, just the IMEI is printed. Sorry

G955FXXU1AQH3 unlocked, bloatware grabage problem.

Hey fella's, and ladies. I just got my G955F, bought inside of the US off of the same person I usually go through. Turns out It's a UK model that came with Vodafone bloatware and shows 4G instead of LTE (even though it IS LTE). Is there a US variant? And if so can I flash the phone with any G955F variant software using odin? So I guess I'm asking, what is the best, and purest firmware if I am in the US. I have T-Mobile and I'm in Cali. Thanks ahead. (Sorry, but I posted this in the S8 section originally, like a dumb-dumb)
Also, could I flash with G955U unlocked firmware?

http://updato.com/firmware-archive-select-model?exact=1&q=SM-G955F
Here you can download the US ROM and use Odin to flash - these are official ROM's so Knox will not be tripped

NO
You CANNOT flash a G955U rom to a G955F device
It will definately soft brick or even hard brick your device
You can flash this rom ( https://www.sammobile.com/firmwares/galaxy-s8/SM-G955F/EUR/download/G955FXXU1AQH3/184528/ )
No bloatware, multilang and fast updates.

DON'T GIVE WRONG INFORMATION!!!
If you don't know what you talking about, then say nothing!
You CAN'T flash G955U FW to a G955F
Do you know the difference between the G955U & G955F?
If you did, than you would have known the answer!!!

He has a G955F phone with a UK ROM on it... he wants a US ROM so the link takes him to the US ROMS for a G995F phone
I didnt answer the last bit about the G955U as I only just saw that - and just to clarfiy the G955U is the Snapdragon version so no, a Exynos ROM will not work

Got it. Couldn't find any US firmware on that page. Part of my question about the US firmware, or multilang firmware comes from the fact that Walmart sells G955F's. I would imagine whatever firmware is on there would be what I would want. Just don't know what that is.
-Thanks for all the replies so far. If I can't figure out what firmware comes on the US Walmart G955F phone, I suppose I will go with the variant listed above.
-Also, will VoLTE work on the multilang rom? Or is there a rom that works with T-Mobile and VoLTE? And if anyone is wondering, I wanted to Exynos variant, that's why I didn't buy G955U.

Well, I went ahead and used this firmware. Really like it, no problems at all and its exactly what you said it would be (hopefully its got great support as well). Appreciate the direction. Thank you.
If anyone finds out what comes on the US released (Walmart) G955F, I would really like to know. I've been searching and searching, and can't seem to figure it out.

Hi guys, I've just got a G955F as an upgrade from Vodafone UK with lots of their bloatware. Can I flash any other firmware over it without tripping Knox or invalidating the warranty? I'm in the UK btw.

Flashing My Note 20 Ultra 5g N9860(BRI) with SM-N986U1 firmware

Hi,
I was wondering if its possible to flash US unlocked firmware onto the unlocked dual sim Taiwanese variant of the Note 20 Ultra 5G (SM-N9860).
There are certain features like Samsung pay that is somewhat limited for me because its still shows the region as Taiwan.
Of course I don't want to brick my phone but wanted to see my options in terms of changing the region to a US version.
Also, just to confirm, there is no way for this 5G variant to get 5G with US carriers, correct?
Thanks

SAme question here.. can anyone help please? also can anyone help in this issue:
I am living in UK, have note 20 ultra 986U1. all 5g Bands are not active, on android 11 (UI3.1) there was a way to access to service menu and enable all 5bands. and I was using the 5G here. now, I updated, and that can not reach seavice menu to enable right 5G band. anyone has any idea what should I do? even I can not flash with UK rom, as UK rom is for Exynos, but mine is snapdragon. any other idea maybe? or other rom that works with my phone and also enabled 5G bands?
do you think if I just change the CSC , my problem will solve? if yes, which CSC I must flash and how?

Reflash AT&T 20 Ultra to Unlocked Firmware?

I've looked through threads of people doing the reverse of this. It's been a few years since I've had an android and was running nexus devices then. What's the process to flash an unlocked firmware on an AT&T locked 968U to the 968U1 firmware (assuming there aren't issues doing it)?
Are there any other pitfalls I need to be aware of prior to doing it other than the wifi calling?
If this is already posted somewhere else, please feel free to point me there. I didn't see any info about going from a carrier locked 968U to unlocked firmware.
Thanks in advance.

I just did this today went from TMB locked one to unlocked (For a family member) mine is unlocked. All went well no problems at all. Just download the U1 Firmware you want to flash and for CSC use home_csc (In ODin) so you can keep your data and probably the wifi calling feature too ( i did that all features are intact). Use the Odin and firmware from Ota and non Ota thread . Enjoy

I flashed the U1 firmware (ATJ3) onto my AT&T Note Ultra, then flashed the Home CSC from the AT&T U firmware. I have VoLTE and WiFi calling.

Help!
Hello all, I have a Note 20 Ultra 5g that is unlocked and I'm looking to flash the original ATT firmware for this device.
Having this unlocked version on Firstnet has been nothing but problems and I don't have access to band 14 or wifi calling.
I see this thread is a little old but if anyone could help me out or send me in the right direction I would greatly appreciate it!
I have rooted some of my older phones several several years ago so I think I could pick this back up pretty quickly. I know over the years things seem to get easier and have probably changed quite a bit since I've last done something like this.
Thanks in advance!

AT&T hasn't released any "official" firmware for the Note 20 series.
Since Samsung firmware is multi CSC, just flash any firmware with the same build number as the AT&T variant and use your AT&T SIM card.
Go to this thread https://forum.xda-developers.com/t/ota-and-non-ota-firmware-for-n986u-and-n986u1.4143833/
Make sure you know what device you have, U or U1. Then grab the appropriate version.
Fir AT&T U devices, N986USQU2DUCA or N986USQU2DUCA will work.
For AT&T U1 devices, N986U1UEU2DUCB is the most recent version.
