So I have this S7 International version and I've been reading a lot and realized that my CSC is ECT for Nigeria NG I'm thinking this could be why my data is so damn slow compared to my HTC.... Is there a way to change this and how would I go about changing it... I'm on MetroPCS (T-Mobile) in the USA.
Thanks
go to sammobile . com and download the firmware you want and use Odin to install. Theres plenty of other software, whether it's UK, Luxemburg or any other. Plus you can get the latest April security update
I just wonderin what's the best country, I was thinking Austria T-Mobile but honestly I don't know much about Foriegn carriers
But seriously I waited 4 hours for a 2GB file to not gethalf way done I just stuck my sim in my HTC and it's halfway done in 5 minutes
Make sure whatever you download is of the 930F variant and not any of the snapdragon firmware. Most US based ones are of snapdragon type.
I know that I was just wondering if it matters what country I download whether it's Austria or Germany Poland UK etc
Holy crap this has fixed everything. I now for the first time have an LTE signal. Unfortunatly it's not rooted anymore but I"ll take being able to use the internet over having a linux distro on my phone any day
Glad to hear you sorted the problem. Best way to select ROMs is to look for countries with matching LTE bands to your carrier. Most likely case is that CSC might limit bands or do something on that area.
Hi,
I just received my unlocked G930F from B&H today (What a beautiful phone).
Exynos 8890 Octa-Core Chipset
According to "Phone Info" this was made on 2016.07.09 and assembled in Vietnam.
Product Code SM-G930FZKLTPA
Firmware code & Active code: TPA
Aavilable CSC codes: ALE, ARO, BVO, CHO, COO, EON, PCW, TPA, TTT, UPO, UYO
CSC Country: Panama
Mobile Operator: Home / 310410
I am located in New England.
The two Mobile Network types I have seen displayed so far under the SIM Card Status are; LTE and HSUPA
I did a manual update today and the current version is:
G930FXX1APG3/
G930FUUB1APEQ/
G930FXXU1APEQ
I have been trying to read as much about this version of the S7 as I can so I don't have to ask too many questions, I do have a few at this time though. My S4 was also on Straight Talk and would not update past 4.2.2 I needed a more reliable phone so now have this S7. I want to get all the security updates as well as any of the Android updates as they become available. Straight Talk is not so good about sending updates and I understand AT&T drags their feet on update certifications. Also, it appears some countries are more likely to get updates than others. I understand the UK gets frequent updates, I am not so sure about Panama.
I've read inserting a SIM from another GSM carrier such as T-Mobile even if not activated will allow updates via wi-fi; does this work to get the newest updates?
I want to keep the stock Samsung firmware for the moment & with that, is updating from the phone my best bet or is there a better way to get the latest updates?
Is there any benefit to having the CSC country reflect say, the UK or the EU as opposed to Panama? If so, is there a reasonable way to accomplish this & could you provide a link for me to look into it?
That's it for the moment, I have more reading to do...
Thanks!
I have purchased an unbranded G930F from B&H for use on AT&T in the U.S. The phone currently seems to work fine with AT&T LTE, here is what I've determined using Phone Info and About Phone:
Country: Panama
Product code: TPA
PDA: G930FXXS1APG3
CSC: G930FUUB1APEQ
Baseband: G930FXXU1APEQ
Now I'd like to reflash my phone using Odin to fix some software issues from OTA updates not resolved by factory reset. From what I gather, I think the proper thing to do is flash the latest firmware from SamMobile (any region) and extract HOME_CSC from the current Panama firmware. I've read a lot of other guides and threads but a lot of similar questions are unanswered or refer to deleted posts on other sites. So here goes:
1. Does CSC affect my phone automatically working with AT&T LTE in the U.S.? Should I make sure to keep using the Panama CSC since it seems to be working, or does it not matter? If it does, is there a list of certain CSCs that are compatible with AT&T LTE or a specific preferred CSC for AT&T users? Does the CSC need to be for the same model S7 (ie. can I flash a CSC from a Snapdragon model firmware with a G930F firmware)? (found out that requires root, which defeats the point of remaining stock/untripped KNOX)
2. Will flashing a more up-to-date firmware for a different region also change the baseband, or can I safely flash a new firmware while leaving the baseband intact? Similarly, will flashing a more up-todate firmware/baseband for a different region possibly break AT&T LTE? Are only some basebands compatible with AT&T?
3. I don't have Samsung Pay on my device, but I found mixed info saying that UAE and UK firmware include working Samsung Pay. Are those the only ones that do and will either of those affect AT&T LTE functionality or other software features? It's not critical but would be nice to have.
4. I see some custom firmwares list VoLTE support, are there any stock firmwares that do that would be AT&T compatible? Once again, not critical but it would be nice. (seems it's not worth the hassle)
As far as I know, there aren't any firmwares for the G930F that lock out the AT&T bands. You're fine using AFR, XSG (UAE's firmware), and AMO for your csc to use samsung pay. AMO (Spain) has the whitepages feature if you should want it, but I think that MST pay in AMO doesn't work (I don't use that firmware, so can't confirm). I use UAE's firmware and have no issues with the latest release and pay/framework. I've made plenty of MST payments all with no issues. To my knowledge, your baseband firmware does not need to be preserved at all. I recommend you do a complete reïnstall of the UAE firmware and flash everything to avoid issues. I'm on AT&T and have yet to have had any signal issues.
As an aside, only the USA has "4g LTE". The rest of the world calls it 4G. Your status bar indicator for data strength will always show 4G in international ROMS for this reason. In case you were wondering, "4G HSPA" is actually 3G or H/H+ in the rest of the world. United States carriers rewrote the definition of data speeds in the united states so that they can get away with selling lesser services than the rest of the world. Telecoms in the USA are among the worst in the world, so congrats :victory:

I'm new to the forum and phones in general. This was helpful but I'd like to ask a few questions to clarify.
I purchased 2 phones off eBay for use on at&t. One of them came with a UAE baseband G930FXXU1BPJG and one came with G930FXXU1APB4 (which I can't find any info on) The second.. APB4 displays LTE, but the UAW firmware only shows 4G. I just assumed it was not using LTE, but your post seems to indicate that it might be. I never actually ran a speed test, which I will do.
1. How can I get the APB4 on both? I haven't been able to find a download for that or even a google result.
2. Why did the AT&T rep have to manually change my IMEI number in their computer to one for an AT&T s7 before the UAE firmware would even negotiate 4G (it was stuck on H) ?
3. If download speeds on the UAE phone aren't LTE do you have any other ideas I can try?
Thanks in advance for any help.
Hi All,
It's been a long while since I have posted something, but I have been using and reading up on XDA with much gratitude since I joined in 2010. The community represented here is just awesome in every way, and I would like you all to know that. I wanted to ask you guys for advice on the following matter:
I currently own a galaxy note 5 in the Netherlands, which I have purchased in Dubai. I decided on the dual sim model, since I find the dual sim capability for my work and private sim very important. The phone has done me well in the last 18 months (worked without any trouble in NL, and is rooted), but now I think it's time to replace it. My new phone of choice would be the Galaxy S8 plus, preferably the 6GB model. Of course this would also need to be the dual sim version, otherwise I could just buy the normal version here in the Netherlands. I have some friends living over in Hong Kong, which would allow me to buy the phone there.
Now for the hard part. Not only does the phone need to be dual sim, it also needs to support all dutch bands (including volte if possible) and it must be able to be rooted (adblock on its own is enough reason to justify that, let alone all other possibilities). I am used to flashing kernels and roms on my phones, as per the consice instructions found on this forum.
The phone that meets my criteria seems to be the SM-G9550 (6GB) that can be bought in Hong Kong. Would you guys please advise me on whether you think that would function here in the Netherlands and whether I can root it? And if not, what would you advise me to do given the above?
Thanks a ton in advance
@kimi4life
The G9550 is the Chinese/HK variant of the GS8+, and while it does support LTE Bands 3, 7 and 20 (those used by Vodafone NL), the combination of bands, known as Carrier Aggregation (or 4G+), may or may not work. Moreover, VoLTE and WiFi calling (if applicable) will NOT work with this variant.
The reason behind this, is the CSC. Since the G9550 is only sold in China and Hong Kong, it does not have a Netherlands CSC (Carrier Specific Customization), so you'll have all Chinese and possibly even carrier bloatware for China.
There is a way to get a G955FD CSC (EU variant) on your G9550 (CN/HK variant) phone by rooting it and flashing a custom ROM and CSC switcher, you can check Nicholaschum's thread in the Discussion section on how to do that. Do keep in mind that doing all that voids KNOX and there is no way to reset the KNOX counter.
However, the Chinese variant has no custom ROMs, and you'd be better off with the Exynos G955FD variant.
I wouldn't recommend going through all the trouble though, the 64GB/4GB S8+ is pretty good on its own. If you pick up a G955FD, and pop in a Netherlands SIM card, it'll automatically switch to the right CSC based on your country and what carrier you're on. This variant can be rooted, has a few decent stock based custom ROMs, and gets software updates more often than the Chinese variant. You will also have no issues about LTE band compatibility since the 955FD fully supports all networks in Netherlands.

Thanks a ton for the clear explanation! It would seem the G955FD would be the best choice then. I'm not sure if these are also sold in HK, i'll just check online if they are. Small bummer on the storage space, since I've heard it is not expendable when using the second sim. Then again, if I go abroad I might as well switch out one of the sims and place an SD card.

955FDs aren't available in HK, but the dual SIM S8+ has been launched in the UK and is available in Dubai as well.
In fact, I bought my 955FD in Dubai as well.

It has just launched in the Netherlands I heard. Ordered it at the Samsung shop just now - looking forward to it!

Thanks again for the advice! I'll get back to you on the best way to root when I received it
my friend is brining me over a G9550 from HK over the weekend. o2 in the UK have not cleared the s8/s8+ for wifi calling and volte yet, but when they do, where is the link to root and install custom rom and csc on it so i can hopefully get it to work with these services?
im getting the phone for free, so i can't complain with free!

will the korean exynos firmware or custom rom built for that device even work for the snapdragon G9550?!
No need to root for adblocker, you can get adblocker through "Adhell" or "Disconnect for samsung browser" in play store. I don't think rooting is worth it on such a new device with many functions out of the box. Substratum also got samsung support without root.

No it won't.
I have a G9550 (6GB/128GB) from Hong Kong and can confirm Vodafone 4G does not work on it, only 3G

That's odd considering it supports the necessary bands.
Have you set it to LTE mode?

I thought it would support it straight out the box too but it only connects to 3G:

You sure you have the APNs right?
Dial *#2683662# and tell me if a Service Mode menu pops up.
Erm I did get some OTA configurations when I put my Vodafone sim card in but I didn't accept them settings as it was browser changes and I didn't think they affected my data connection, could they be it?
It said:
service mode
menu not exist
press back to continue
current command is 1000
Edited to add:
I just looked in my access point list in settings and it does come up with Vodafones access point settings
Edited again to add:
I spoke to Vodafone who checked my APN settings and assured me they were correct
Edited again again to add:
Added the APN settings manually, restarted my phone and now it works with 4G ?

That's because the Chinese variants don't support carrier aggregation on the same bands used by networks in the UK.
I have 4g+ in china and Hong Kong but not here on voda uk
I got an Exynos S7 SM-G930F a few weeks ago, firmware is Australia version. It kept locking up randomly, even from the first time I powered it on, so Amazon seller sent me a replacement, which is also Exynos S7 SM-G930F, but UAE version. UAE one hasn't locked up yet, but I've had it less than a day.
I have to decide quickly if I will return the Australia version and keep the UAE one.
I'm in US, on a reseller of T-Mobile network.
1. Are there any differences in hardware between these phones, or just firmware?
2. Can I safely burn the Australia/UK/etc version of the stock firmware on this phone? Does it even make any difference, other than having an extra "United Arab Emirates TRA ID" section in the About page? (I'll maybe root and install LineageOS etc later, but wanted to try stock first.)
Both seem to work fine, making calls, transferring mobile data, etc. Both have legit IMEIs and seem real.

G930F is the hardware, you can flash any ROM for that model S7, might need to check the "Repartition" option in ODIN if you are changing CSC's
So the replacement phone hasn't locked up even once, so it must have been either a hardware or Australia firmware issue. UAE firmware version has been working fine.
