EU firmware is for Exynos and US SGS21 has Snapdragon. Not compatible.

FW SM-G965U1 (USA Unlocked) on S9+ SM-G9650 (China Unlocked), is it possible?

Hello, i'm in Italy and i bought S9+ 128GB SM-G9650/DS (China Unlocked Factory) to have Qualcomm Snapdragon CPU.
Can i flash FW SM-G965U1 (USA Unlocked Factory with Snapdragon also) with Odin?
Thank you
nothing?
Nope, because you will brick the device
No because the model number does not match, odin will not allow it to flash.
Prince comesy odin may allow it to flash but your un uncharted waters there so no idea what will happen
By any chance do we have any Odin method to root the Canadian Snapdragon versions, bypass the SM-G965W bootloader?
Nope. And dude a simple search would have told you that.
thank you all for the answers
you can make a rom out of the usa carrier firmware and flash it via twrp to your G9650 no problem. Don't let these noobs tell you otherwise.
@travis82
ahahahahaha I would need a guide to do it, so I was asking for the simplest thing, namely ODIN
I don't even know if it's better the G9650 version or the G965U1 version ...... in both cases, I have to use it in Italy with Italian SIM
He asked if he can flash firmware with odin, creating a rom and flashing via twrp is quite another matter lol
Can I flash the U1 Firmware with Mexico's Telcel CSC??
Hi guys, I made a quick comparison between 3 models (mine is the SM-G965W - Rogers) as recommended by some xda members. Some were saying it may be breaking the phone entirely, and some were saying it is working. Based on those specs all three models are pretty much the same including the Supported Cellular Bands. What is your opinion based on your expertise on this take?

sm-g9650 hong kong firmware to usa?

I've been reading up on firmware options on here but can't figure out a straight answer. I have the hong kong version of the s9 plus 256gb with the snapdragon chip. My question is can you use odin to flash USA firmware to it? Without getting a hard brick.
Like the fully unlocked firmware for us models that isn't tied to carriers. Thanks.

i have the same question...any answer?
I do not know, but it would be great if you would upload your firmware to https://androidfilehost.com
Also, would you please tell me if you are able to use the native call recording functionality that Samsung pushed out in May with your phone
Sorry for no punctuation my keyboard is screwed up for some reason
Thanks Very Much

Based on what I've reviewed this look to be the best option to do so once you confirm the firmware is compatible.

Can I install US unlocked firmware on Canadian Note 10+ ?

Canadian Note 10+ N975W is unlocked, it is the Snapdragon 855 version.
The US Unlocked Note 10+ model is N975U1, it is also the snapdragon 855 version.
But, recently, the US unlocked model is getting frequent software updates. So, I was wondering can I install the US unlocked firmware to CA unlocked Note 10+?
Has anyone tried that?
Yes you can

4G band firmware or hardware?

Hi
bought a p20 lite LX3 in USA, which it's not prepared for 4G bands here in Spain as per link and image information
https://www.kimovil.com/es/frequency-checker/ES/huawei-p20-lite
Does anybody know that if I apply a stock custom rom from LX1 model the 4G bands will work? or it's an issue that it's non solvable through firmware?
Thanks in advance

dont know if using stock custom rom will help, but, with my old p9 , wen i instaled android 8 china version, phone didnt connect to operator, only when i patched it with europe network patch, all bands worked as needed for me, but ofcorse, its european phone with china software, so i guess it is software related not hardware!

Question Do anyone try flash BC52 with BC72 firmware?

Anyone tried flash BC52 model with BC72 firmware? i would want to flash SEA firmware on my BC52 model, is it possible without root just use new flasher.
i wouldn't.but i basically been flashing diff from from hk,sea,,ru and china. their all the same but china is more light as in you can by default remap the assistant button and also data un-enrypt is friendly
当然,XQ-BC72 Dual 可以刷入 XQ-BC62 Dual 或 XQ-BC52 Dual,但我无法反过来测试。
Of course, XQ-BC72 Dual can either be flashed into XQ-BC62 Dual or XQ-BC52 Dual, but I can’t test the other way around.
Un-encrypt is the first thing good from china XD
