Flash g930u on g930f, just to be able to use Samsung Pay - possible? - Samsung Galaxy S7 Questions and Answers

Hello everyone, I have a Samsung Galaxy S7 (G930F - Exynos - International).
I've rooted the phone, but fully unroot it back with a stock rom. So, knox has been tripped because of it. I don't really care about root anymore.
I was wondering if it's possible to flash a g930u firmware on it and be able to use Samsung Pay afterward.

G930U firmware is for the snapdragon US models, you'll brick your phone trying to put it on the G930F exynos. Totally different SoC.
What's your goal exactly? If it's better US carrier support you can try flashing the CSC utility but it needs TWRP https://forum.xda-developers.com/galaxy-s7/development/utility-flashable-csc-selection-30-t3392949

so i can use samsung pay.
currently, samsung pay will not work on S7 international or exynos model.

So according to this https://forum.xda-developers.com/s7-edge/how-to/samsung-pay-knox-warranty-void-t3549449
CSC has to match your country, so you're likely going to need to flash that CSC utility to a US carrier. Since the G930F is the international version there's no stock US firmware for it, so custom zips are likely your only option.

You definitely should NOT try flashing a U firmware, because lots of things will go very badly. It's not even made for the same SoC as the F (international) version.
Tripping Knox has blown an e-fuse on your motherboard, so unless you replace it there is no way to restore it to 0x0.
And as for using Samsung Pay, that is not possible, because of Knox being tripped. Currently there isn't a workaround for that and so using Samsung Pay is not possible.

Although all the SM-P905 have the same hardware, they're customized for specific cellular provider and bootloader is locked.
You can try to flash with Odin but I believe you will have a fail as it detects wrong firmware, like P905V is for Verizon, P905A for AT&T.
they're not interchangeable although mainboard is exactly the same.
No. USA firmware is not compatible with international devices.
P905V is not the same device as P905. The P905V is a locked device, with branded firmware locked to Verizon devices. T905 is the T-Mobile USA variant of the exact same locked firmware problem.
You need to use international firmware for the international P905.
Confirmed, I have tried T905XXUBOI1 , but failed during flashing unfortunately
hopefully someone can solve it one day , it shouldnt be difficult

I own and have opened different LTE tablets, I can tell they are the same tablet, only Samsung has this ability to
unlock the bootloader and load the desired firmware. I can swap mainboard of SM-P905V to a SM-P907A tablet or vice versa without
any problem which indicates they are identical tablets except firmware and bootloader.
Any way, Lollipop 5.02 and 5.1.1 have no differences as it depends on the model.
Like Tab Pro SM-T900 is 5.1.1 but Note Pro SM-P900 is 5.0.2, don't bother to load different firmware from another model.

How to replace Chinese firmware(G9300) with US one(G930A/G930U)?

I have bought a Samsung Galaxy S7 in China. It comes with Chinese firmware (has English language though) but mostly with Chinese software, bloatware and without Google play store. So it does not sync with Google, searches go through Baidu, I can't find and install most apps so it's essentially not very fun to use.
So i want to replace the firmware with any US firmware like G930A, G930U etc. I personally think its possible cause Chinese S7 has Snapdragon 820 chipset like US S7. So basically the hardware of Chinese & US variants of S7 are same.
Just i need a proper step by step guide or ODIN tutorial to make this change. I am really tired of Chinese apps and bloatware. So please guys help me to get ride out of this. Please.
updato.com has all the firmwares for the various models and countries, and it has a step by step guide for flashing with Odin.

Boot into download mode, whatever model it says in there is the one you can flash new firmware for, do not try flashing firmware for the wrong model S7 or you can brick it
Exceptions are G930V can use G930U firmwares, and FD can use F firmware, I am not aware of any others
I recommend SamMobile for the firmware download and Odin for flashing it.
Read carefully the flashing instructions.
There are many threads with tutorials, we'll not going to post another tutorial here. Just use the search button and you'll find all the information you need about flashing with Odin.

I know how to flash with ODIN. But i wanted to change my firmware. My S7's model is SM-G9300 which is for Chinese open model. But in this model, there is no google apps and lots of bloatware everywhere. So i wanna replace it with any US firmware specially with SM-930U firmware. Cause i heard it gives smooth performance and bloatware less.

i saw some user changed their S7's G930A or G930V firmware with G930U firmware because of all the US model of S7 has snapdragon's hardware setup. That's why i am interested cause my G9300 also has snapdragon's hardware though it Chinese model. I know i can't flash exynos firmware in snapdragon's model because its completely different hardware setup.
So i wanted to know did anybody can successfully changed their G9300(Chinese) firmware with any US firmware? If did then what's the process? Or how can i replace it? Is there any way to do that without ODIN like with 'dongle' or 'magic flash box'? These are my queries.

I already explained, only 1-2 devices have other model firmwares that are compatible, yours is not one of them, nothing to do with hte snapdragon hardware, bootloader etc is different and will BRICK
See here for TWRP and try custom / root to get Google services

Hi,
I bought Samsung Galaxy S7 SM-G930S from the store which was converted into SM-G930FD as I was not having Korean sick apps installed in my mobile and there was no Korean logo of "BANDLTE" while switching off and switching on, when I saw my phone model name it was SM-G930FD and was supporting dual sim both had a same IMEI. But when I restarted my mobile after getting home phone got locked with this message "Custom Binary Blocked By FRP Lock" so decided to got into boot menu there I saw SMG930S written so i flashed mobile with SKT Korean firmware of smg930s but when I installed it I got tons of Korean apps and getting "BANDLTE" logo while switching off and on my phone I lost that Samsung Original logo which I had when my phone was converted into smg930fd. Now I want to switch back to Smg930fd settings/firmware so get rid of these Korean apps and Model to be appear as SMG930FD as the back of my Samsung Galaxy s7 glass has a phone model SMG930FD. I don't know Shopkeeper scammed me or what I told him I wanted to buy SMG930FD but he gave me this converted phone Kindly help me to get back to SMG930FD firmware/settings

The same experience... If you are not on Oreo, I advice you to stay on Nougat or even Marshmallow.
Although this post has been posted for a long time but I still want to ask you that how did you get the g9300 device rooted properly?

Which US (Qualcomm)S7 to get?

I'm looking at upgrading from my Moto E4 and settled on the Galaxy S7 over the Pixel due to the MicroSD slot. I now have questions as to which version to get.
I understand that it's relatively simple to flash the unlocked firmware on any of the devices. Could I just simply find the cheapest, good shaped S7 and flash the unlocked firmware and be satisfied?
I'm currently on Sprint's 1-year free service promotion until September 2018. So Sprint compatibility is needed for a while. After that, I want the freedom to be able to hop back to AT&T or Verizon (or one of their MVNOs).
Should I just buy a Sprint S7 now, then when my service is up, flash the new firmware then? Or should I buy a T-Mobile version and flash the 930U firmware right away? The universal unlocked model is significantly more expensive, so I just want to make sure I'm covering all my bases.
Depends on your goals. Flashing via Odin is quite simple and easy for the S7, but the US models all have a locked bootloader. That means you can only flash stock firmware files, and nothing custom. No ROM's and no TWRP.
If you're happy with than then you're set, if not you'll need the international Exynos model, as it can be unlocked and flash custom.

no ROMs is OK with me. the exynos version won't work on my current provider, so can't go that direction anyway.

Purchased the G955FD, should I worry about CSC?

Hi all
I just purchased the International S8+ dual Sim variant, the G955FD, from eBay.
I live in Canada and will be using both a Telus Sim and a Rogers Sim.
Is there anything I need to worry about regarding the CSC type?
I found this thread, https://forum.xda-developers.com/ga...ility-flashable-csc-selection-v1-0-0-t3605264
So it seems easy enough - I just don't know if and when I need to change the type.
And should I even be changing it to Telus or Rogers, since they don't have this variant?
And yes this is my first Samsung phone
And input is appreciated!
Edit: if it matters, I don't use wifi calling for either Telus or Rogers. I also plan on simply rooting the phone with magisk to make some mods, and put on Android pay
Just curious. Where was your Duos sourced from?

Great question.
As I did more reading on the device I checked the eBay listing and didn't see exactly where it's sourced from. I should have it in hand by Wednesday and I'll try to validate then. What should I be looking for?
Is there a specific source country that works better than others?

Firstly, congratulations on the new phone. I've got a 955FD as well.
It doesn't matter where the phone is sourced from, although if you want to check, you can go in to settings > about > software information > service provider information and see the CSCs listed there, in this format 'XXX/XXX/XXX'
The first one is the active CSC on the device at the time of you checking, the second one is the CSC for the SIM card currently being used, and the third CSC which can not be changed at ALL is the one from which country the device was sourced.
I'm in Pakistan so for me the CSC format is: PAK/PAK/MID
First two are PAK because that's the CSC for my SIM card and because it's the active CSC on my device, however the last one always remains as MID since that's where my device was imported from.
Canada has no CSCs available for the G955FD sicne it's the Exynos variant and the one sold in Canda is the G955W which is Single SIM and SD835, however the CSCs should work regardless of device variant. You can flash the CSC for whichever is your main SIM card, or whichever you use more often. Either Telus or Rogers, entirely up to you.
The benefits of flashing your carriers CSC is getting stuff like VoLTE and WiFi calling (and sometimes even 4G+/LTE+) to work. No harm in doing it since you're going to root anyway, so make sure to flash whichever one you prefer.
Magisk, rooting, mods, that's all fine, but do confirm properly about Android Pay before actually going ahead and rooting.
Samsung Pay will not work in Canada with the 955FD, and will definitely not work anywhere at all once you've rooted and tripped the KNOX warranty counter. Android Pay can be tricked into working by passing SafetyNet with Magisk, not sure if this still works or not though.
Other than that you should't have any issues.
If you've got any more questions, just tag me or quote this post and I'll be happy to help.

Thank you!
The break down is very much appreciated.
Is there any issue with flashing (via TWRP or Odin?) random CSCs?
Since there is no G955FD in Canada, I don't want to break anything.
I'm very comfortable with flashing and modding the heck out of Android phones, but Samsung seems to be a totally different ball game lol
I obtained a Galaxy S8+ G955FD Dual Sim from e-Bay as well, sourced from UAE. I was able to register US issued MasterCard and Visa on Samsung Pay.
I am on T-Mobile, other than not having WIFI calling, the G955FD works great. Rooting the phone would most likely break the Samsung Pay. So that is a decision you need to make.

No issues at all. Plenty of people in the US using the Exynos variants and they've all flashed the necessary CSCs when required.
Flash TWRP using Odin and then use the flashable CSC selection mod to choose whatever CSC you'd like to flash.

Thanks guys.
I'll assume that flashing TWRP is going to trip knox, right? therefore flashing a localized CSC is going to require me tripping knox.
Which hey, if Android Pay works fine then i don't need to use Samsung Pay i guess.
If i dont change my CSC, then will my phone receive OTAs when they're released in whatever country its sourced from?
Will changing my CSC to a Canadian one mean i'll start seeing Canadian OTAs?
What about manually flashing official images? Do i have to make sure that the file i'm using matches the CSC as well?
And lastly, are the S8 and S8+ images the same file? Or are ROMs for the S8 100% compatible with the S8+?

Flashing anything other than a Samsung Stock ROM will trip KNOX. Including TWRP. The Canadian CSC using the flashable CSC selector will have no effect on KNOX since it'll already have been tripped because of TWRP.
If you don't change your CSC, and are rooted with Magisk and have mods, you won't get any OTAs since the phone is rooted.
And no, changing to a Canadian CSC will not get you Canadian OTAs since the Canadian variant has the Snapdragon 835 and the 955FD you're getting has an Exynos 8895, so OTAs and stock ROMs are most definitely not interchangeable.
Manually flashing stock ROMs is possible, I suggest you flash the newest one available when you get the phone, which is G955FXXU1AQK7. And honestly, because there's been a major overhaul in how CSCs work on the S8, you can just grab any firmware and flash it and it'll stay on the CSC your phone came from because it can't switch to a Canadian one without you manually doing it.
S8/S8+ images are not the same and you can't flash S8 images on an S8+ or S8+ images on an S8.
Only S8+ (G955F/G955FD) stock ROMs will work on your phone.
However, since you're going through all the effort to root, change CSC and flash Magisk Mods, might as well use a custom ROM?
They get updated regularly so you don't have to keep flashing the stock ROM, and you can still have root, CSC mods and everything but with a few extra features and possibly better performance.

So maybe the first think i do is try and see how long i can go without having to root it / put on TWRP.
If i dont touch anything, including the CSC, will i receive OTAs as the source country gets them ? or am i out of band and therefore am on my own?

It's CSC is XSG/XSG/XSG which looks like "United Arab Emirates unbranded"

First thing im noticing is that it's not restoring my Google backups
Is this because it's a samsung phone and i need to use the Samsung backup feature instead?

It is indeed a UAE phone, good place to be sourced from since XSG gets updates fairly quickly compared to other CSCs.
What issue did you face when restoring the Google backup and how exactly did you try to restore it?
Some people have reported that the Samsung Pay app installed on XSG phones works well in other countries, so you can try that out if you want, otherwise Android Pay should work fine.

Thank you!
Yes, i actually just got a notification for an OTA. I think the December security patches.
Which is aweosme, so i'm not going to flash a different CSC because i dont think i need to at this time!
Regarding the backups; I was expecting to log in to this phone and get all my apps that were installed on my last phone.
But then i realized that htis is a brand new phone and i dont have a backup to restore to!
So i just manually installed the apps i needed and was on my way.
Lastly, yes, i just installed Android Pay and it works perfectly fine.
Thanks for all the help!

If your previous phone is an android phone and you use Google ID on that phone, you should have no problem restoring your apps. The Play Store remembers your Google ID and all of your apps should be restored if you log in with you Google ID.
Im noticing now that of my 2 SIM cards, one is usually around 80% strength, while the other is around 50% strength.
is this possibly an issue with using the wrong CSC for my region?
Or maybe since only one SIM can use LTE at a time, the other SIM is stuck on 2g/3g and it just has crappy reception becuase those towers arnt really in use anymore in my area?

Yeah, that is probably the case.
I had taken my 955FD to UAE earlier this year, used my local UAE SIM in slot 1 for LTE, and my Pakistani SIM card in slot 2 so I could still get texts on that number. Battery life did take a significant hit since the signal strength on one of the SIMs was quite low.
Changing CSCs may or may not have an effect on the signal strength. A good way to check is by using the SIM with poor signal strength in another phone with the same network mode, and see if you get the same results, if so, changing CSC will do nothing. If the difference is very large, then you could consider flashing the CSC although I wouldn't recommend rooting your phone just for a CSC change, especially if you aren't facing difficulties in making calls/sending texts/using data.
I have a 955FD XSG also. Using AT&T. I managed to enable VoLTE by quickly putting the sim on an att branded phone and returning the sim to my phone. I now have the VoLTE toggle and calls are placed over LTE but I can't seem to get the wifi calling toggle to appear.

WiFi calling won't appear without the AT&T CSC.

Change SM-G930A to UK or EU ROM from AT&T/Sprint ROM without breaking Knox?

I'm in the UK and I've acquired three brand new sealed S7's - SM-G930A - which I would like to sell, but they appear to have an AT&T/Sprint specific version of Android - I've booted one and it keeps trying to install DirectTV and other US-centric apps.
Is there a way to put these on a UK or EU ROM that doesn't have all this unnecessary bloat, so that they can be used outside the US WITHOUT breaking KNOX (which would mean I am unlikely to sell them at all?)
Thanks!
The AT&T variant of the S7 is built upon a Snapdragon CPU. All of the European variants are built upon a Exynos CPU. Breaking Knox isn't your biggest issue; you can't install a European version of an S7 ROM at all.
Additionally snapdragons have a locked bootloader, so you can't use a custom ROM as work around either.
Your best bet would be flashing the G930U firmware, it's the unlocked firmware for Snapdragon that has no carrier specific bloat. It can be flashed via Odin without affecting Knox, but you may need the patched Odin for it to not give mismatch errors. https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
