Purchased a S7 advertised as a NiB 930A. Showed up flashed with 930F but the markings on back of phone were 930A. I know in most other threads, folks recommend it be sent back to seller, but he has offered a partial refund to make it right.
My main concern is security. I don’t know who installed what on this device. Would reflashing it be a reliable method to get this device back to stock and ensure it is secure?
Any other recommendations? I would like to keep it if possible and maybe flash it to 930U.

Install "android phone info" from playstore or "cpu-z" and identify which cpu the device has, you will then know what you can and cannot do with your phone.
G930F=Europe
G930A= USA AT&T
G930U= USA (Exynos) Unbranded
CPU Exynos = Brilliant
CPU Snapdragon =Nightmare.
It's snapdragon att

Try flashing G930U but you'll always get limited reception in a different region than the USA
Thanks for the suggestion. I already sent it back.

The G930U is snapdragon, the USA doesn't have an Exynos model

I've have a G930S (S7) from SKTelecom is there any way i can remove all the unwanted carrier apps and flash stock rom to it?
If its an Us model, I don't think there is a way but you should still check out the s7 theards for the snapdragon versions
Good luck

Nope it's a Exynos Processor (8890)
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?
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
So i just dont know if im looking for the right stuff or what..
Id like a rootable ROM for debloat and performance reasons.
I have a Galaxy J7 SM-J727U..
Just got it from the store and i can find barely any info on this Model.
Does it have a different name? or just no development for this device?
Thank you
I've got the same phone, and I'm in the same situation. I've got 15 days to return it if I can't find a viable root option, but it seems decent for the price. I've gone through a lot of the steps for trying to root similar models, and in every case I simply can't flash anything with Odin. It gives the error "secure check failed". Everything I've looked into about this seems to point to the "OEM unlock" option under developer options, which this phone doesn't seem to have. I would also love to know if there's any potential for progress on this. I'm willing to put in some research and testing, and I'll let you know if I find anything anywhere else.
The U usually stands for UNLOCKED(as in any network/carrier)
Does not necessarily mean the bootloader is unlocked which is likely if the result is 'secure check fail'
What are the specs of this device and country of origin?
Anyone please say the exact CPU used in ths model. SM-J727U.

That's wrong, sorry. I saw one of the YouTubers Boost Mobile variant (J7 Perx) of SM-J727 with installed Snapdragon 625. I've sent this question to the Samsung support in Twitter, they've confirmed my suspicion of the Snapdragon-based US device. But I was unsure. And here I am completely sure of Snapdragon 625 inside J7 2017 US version.

It was my understanding he is in Ukraine, and there the j727u is the Exynos model, as is the US j727u. The j727p and t models use the snap dragon chips

Yes I am the Ukrainian resident, and her we can obtain the SM-J730F. This is a real Exynos 7870 device. But yours J727U might have a different one.
EDIT: One of the users said that there is indeed Samsung Exynos 7870 inside the unlocked model. Meh. From the wompshmack's post the Download Mode looks to be verifying the signatures.
I have a J7 that is SM-S727LT. I can't find anything on that either

Can I ask you to look for CPU model in your phone? CPU-Z should provide it.

A bit offtopic, but there also is the SM-J727S model, which is the Samsung Wide 2 (or J7 for Souh Korea, sold by the SK Telecom carrier), there is TWRP for it. The CPU is also Exynos 7870.
Theoretically the same rootmethod can be used. Can anyone test?
ANYONE ROOT AND TWRP J727U ?? HELP.. i see no option to enable oem unlock also why.. got my htc rooted then if failed screen damage lines ect fault of too many drops i guess so got this galaxy thinking it will have a twrp ect as its a galaxy yet i find nothing, my luck..
also it was consumer wireless carrier, i cant find prepaid cards for this why ? annoying.. i can send a few to a paypal for help here.. tried odin flash twrp pop says fail.. adb commands the phone so can i flash twrp like that on command prompt.. i need twrp for j727U BUT CANT FIND IT lol
Is there anything for the SM-J727U?
Baseband version J727UUES3ARF1
which variant do i use for galaxy s8 from japan? Sm-G955J / SVC35
Please
variant of what? you looking to stay w/Japanese or go to another region/country?
I just want to use an operator-free rom stock, but I can still use it in Japan
Thanks for help!
What's Japan use for cell svc, GSM? Exynos phone? If so pretty much any custom Exynos ROM, with the version appropriate CSC ought to work just fine.
Maybe it's out of topic, but kinda similar with my question, and the last reply is still quite recent.
I just got a used s8+ g9550 (TGY/Hongkong). I looked at Phone Info app, it comes with Hongkong PDA & CSC (G9550ZHU1AQG6), and US version of BL & CP (G955USQU1AQGL). Still on Nougat 7.0.
It works just fine here in Indonesia. But I'm afraid it won't be getting any OTA updates since I'm not living in China. Is it actually OK to mix up the firmware (AP, CSC,BL,PDA) like that? What versions are compatible with my device?
I'm totally new here. I don't even know why there're 4 firmwares for each device, and what each one of them is for. All I know CP = Modem/Baseband, BL = Bootloader. Mind to explain it to me? Thanks

I beleive your phone is a snapdragon processor not exynos - if it is chinese, I think there may be a way to unlock the bootloader but I am not 100% sure of that. I know that the S7 Chinese was able to be unlocked but there was a special ap you had to install in order to do it.
I know I haven't helped much but I wish you good luck...

I'm looking to go US, T-Mobile to be specific. What do you suggest?
I wanted to flash the global rom (SM-G935F) from SamMobile to my SM-G935V which has bloatware related to Verizon Wireless (USA Carrier). But since these models have different SoC I don't know what will happen so I don't risk. I'd be happy if someone who tried this answered my question.

I don't need to try it to tell you that its a bad idea. If you search the forums you will see hundreds of threads for different Samsung phones where people did exactly what you did and they bricked phone (hard or soft). You cannot take an Exynos ROM and put it on a Snapdragon SOC. You risk damaging the phone.

It isn't a "risk", it will 100% brick your device.
You can try "porting" the Exynos firmware to work on Qualcomm but it won't be an easy task.
But, unfortunately, you have the Verizon device, due to the bootloader that Verizon Samsung devices have, you won't be able to flash anything except the Verizon G935V stock firmware, your bootloader will not allow using anything else, it won't boot non Verizon software.
