Flash J327U ROM on carrier-locked phone - Samsung Galaxy J3 (2017) Questions & Answers

Hi, I was wondering whether or not I could flash the J3 Emerge (J327U - Unlocked ROM which has Oreo) on J327P (Sprint/Boost variant). From what I know, the U version is the unlocked version so I'd expect the J327P to be able to handle it. Thanks

You could try it, some different sites say it has Exynos 7570 in which case it likely won't work. Also be careful because the Boost Mobile variant has SD425 but sprint has SD430, but both are still J327P.

That's something I thought about, in any case, I'm attempting to port LinageOS 15.1 to the J327P. I'm now trying to build a device tree.

Any reason not to get the carrier version of s7 if installing a custom rom?

I use Straight Talk (AT&T sim) in the US. I am looking to get a phone I can install a custom rom on. (Still researching which rom). Since the carrier-specific models of the S7/edge are about $100-200 less used, is there any reason NOT to get a carrier specific model?
Since I'm installing a custom rom, all carrier bloatware would be gone. Wouldn't this effectively be the same as the unlocked model, maybe without international capabilities which I probably wouldn't need anyway.
Is the AT&T model the only one that would work on Straight Talk (AT&T sim)? I'm looking for the cheapest variant that will work.
Thank you.
Some may have a locked bootloader making it impossible to flash TWRP / Custom ROMs

There aren't any, you need the canadian or international s7 if you want roms, all american phones have locked bootloaders, there's a half assed root for it but that's it.

Wouldn't the US unlocked version work? SM-G930U

The unlocked part refers to its ability to be used on any carrier, nothing to do with the bootloader, its still locked like all the other snapdragon phones.

Ahhhh....it boils down to the chipset. So the G930F with Exynos looks to be what I want for running a custom ROM.
Bingo.

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?

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.

No problem. Im sure that you will like it even more
If you can, please share a pic from the device info to see which CSC do you have
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.

The right questions? Galaxy J7 SM-J727U

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..

unlock s7

Hi, I came from S4 and teted several Roms. Can I unlock the S7 so easy too?
Unlock what? Carrier, bootloader, or root?
I want to install custom rom CM15 or similar. On my S4 I had TWRP. How can I install it on S7?
Which version of the s7 do you have? I think the Verizon and AT&T versions have a locked bootloader.
Not just Verizon and AT&T, all US models. Sprint, carrier unlocked, etc.

Thank you for the information. So only Exynos versions have unlocked bootloaders?
I believe there's a chinese snapdragon variant that is the only exception, otherwise yes just Exynos.

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

VPN does nothing when the Samsung services are based on the CSC. I have PIA and Adguard but this will not work.

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?
