Hi there, just wondering does any Australian users who own G935FD flashed the Nougat beta firmware? Does it perfectly work with any carriers? And will I still receive OTA afterwards? Cuz I really want to try the new rom but couldn't find any official stock as backup. Many thanks:)
[Samsung Galaxy S7 Edge Questions and Answers] liqn7:
1) Yes

2) Yes

3) No

4) Official firmwares - flash via Odin. http://www.sammobile.com/firmwares/

I'm on Nougat Beta 1 flashed via odin. Definitely recommend.
[Samsung Galaxy S7 Edge Questions and Answers] uggies:
Next time, please read the forum title before posting. As you can see this forum is for news&discussion NOT q&a.

I am an Australia user who flashed Nougat beta 1 as soon as it came out. Haven't had any real problem with it. It has minor bugs here and there but its good enough for my daily driver.
[Samsung Galaxy S7 Edge Questions and Answers] henrypoon:
Thanks for reply, did you flash the CSC given by the beta rom (UK)?
[Samsung Galaxy S7 Edge Questions and Answers] liqn7:
No I flashed a generic XSA CSC from the latest Marshmallow official firmware. Download and extract from the zip on Sammobile. This was an attempt to get Samsung Pay working, but it looks like they're disabled it for Nougat regardless of the CSC.
[Samsung Galaxy S7 Edge Questions and Answers] henrypoon:
Oh Samsung pay currently doesn't work for me since I don't have AE credit card. Which country of the latest marshmallow firmware on sammobile btw ? And for other fields in odin like AP, just fill up the files given by the beta rom, right? Thanks
[Samsung Galaxy S7 Edge Questions and Answers] liqn7:

Yes.
[Samsung Galaxy S7 Edge Questions and Answers] henrypoon:

Thanks for remain, one thing I am still concerning that when I flash back to official stock, will I still get OTA? Since my Galaxy note4 is running on an official stock and still can receive OTA after I flashed many times of different ROMs.
[Verizon Samsung Galaxy S7 Questions & Answers] rtpiercy:
Good evening!

I recently purchased the VZW S7. My immediate plan is to root it and then enable the Samsung carrier info (which VZW disables) so I can get to the engineering screens to check out LTE/network connection information.

I have been searching all over XDA for some type of answer to my question and haven't found it yet. What I can gather is the VZW variant has all the hardware requirements to have every band from every major carrier in the US, however VZW has disabled specific bands in their firmware. This lead me to thinking I will push the 930U firmware to it which, from what I have read here, unlocks all the specific bands as dictated by the SIM card currently inserted into the phone.

Here is my question: with the 930U firmware, how complicated is it to switch carriers on-the-fly, and to have all the bands a particular carrier utilizes?

My main line is VZW, but I also have a T-Mobile line on my Nexus 6P. However, there is zero engineering mode on the 6P, so I am unable to see information like current band, bandwidth, carrier aggregation status, etc. SignalCheck Pro only tells me the band.

So if I want to use the S7 on Verizon and then swap my T-Mobile SIM card in, how does the phone handle this, and it is a hassle once I put my VZW SIM back in?

I hope all this made sense. Essentially what I am wondering is if switching carriers on the fly is as easy as it is on the 6P- just pop the card in and go, with all the necessary LTE bands enabled.

Thank you for your time!
[Xiaomi Mi MIX  Questions & Answers] duraaraa:
I have a question for all the lucky ones of you who have a Mi Mix.

With most of the Xiaomi phones which are released, people are unhappy about the lack of band support for regions outside of China. I know many people in Europe are unhappy about not having Band 20, those of us in Japan would really like to have UMTS Band 6/19 (among others), Australians want LTE Band 28, and people in the US would like Band 12/17.

As you may know, with some phones, it's possible to unlock these bands by putting the phone into diag mode and using Qualcomm tools like QPST. Here in Japan, it was possible to enable the UMTS Bands 6 and 19 on the Mi5 and the Mi Max, but not possible on the Redmi Note 3 or the Mi5S, so it's really case by case.

Seeing as that the Mi Mix is a concept phone people are crazy about all over the world, I am very curious whether it's possible to enable LTE bands and WCMDA bands on the Mi Mix. I don't want to spend the big money to buy one without first having confidence that I can get it to work on my carrier's bands.

So I'd like to start this discussion. Has anyone tried anything? Successes, failures, please post them all!
[Xiaomi Mi MIX  Questions & Answers] KOLIOSIS:
This (QPST) is something I have no experience with,but,interested in the subject:

I'm good with the band support (for now) as what's available in my area,with my carrier,is supported (Bands 2 &4 on T-Mobile US,no Band 12 or 66 yet),definitely would be nice for at least Band 12,if possible,as I believe my area will get it eventually.

One side note & a positive one at that:

My MiMix locks-in on a signal & has better/stronger connections than any phone I've used to date. This was really noticeable while commuting back & forth to work today,unbelieveable signal quality.

IDK if the ceramic body is better vs other materials,but,recent flagships from HTC/Samsung/LG pale in comparison vs this phone.

[Xiaomi Mi MIX  Questions & Answers] SWBgHz:
I may have that 'xtra' mix in a few weeks, will PM you if it pans out and we can see about a software hack to open up other bands.
[Xiaomi Mi MIX  Questions & Answers] duraaraa:
I've heard the Mi5 diag drivers were usable on the Mi5S, which is the same SD 821, so that's strange. What happens when you put it in diag mode and plug it in? Can I see a screenshot from device manager, or some evidence of what the device is?
[Xiaomi Mi MIX  Questions & Answers] krazyken04:
I've got one in hand in the states (where I actually do need to unlock band 12 for T-mobile) and a patch cable I made handy in case this thing goes brick mode from us trying stuff, I'm game to be the guinea pig for science.

Fair warning though, while I'm a web developer that's very comfy with terminal, I'm new to the android ADB world, so pretty detailed instructions / links to guides will be needed ha!

Is that band 4 only on LTE? I've seen many spec sheets and the carrier I'm on only has band 4 for 3g.
[Xiaomi Mi MIX  Questions & Answers] mac231us:
this is what I have gathered from various sources (so yes Band 4 is both LTE and 3g)

Tmobile

LTE Frequencies:

1700 MHz & 2100 MHz AWS band 4

1900 MHz PCS band 2

Lower 700 MHz band 12

3G/4G Frequencies (WCDMA):

1700 MHz & 2100 MHz AWS band 4

1900 MHz PCS band 2

2G Frequencies (GSM/GPRS/EDGE):

1900 MHz PCS band 2

ATT

AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands

LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz),

Band 4(1700/2100Mhz)

LTE	B29 (700)

LTE	B30 (2300 WCS)
[Xiaomi Mi MIX  Questions & Answers] emann56:
That still doesn't mean the WCDMA Band 4 is enabled. It's possible to have LTE band 4 and not have WCDMA Band 4.
[Xiaomi Mi MIX  Questions & Answers] mac231us:
Yes....was just giving the bands and frequencies I know for two GSM carriers in the US. Monitoring the bands at various locations by something like signal check lite (much easier to use/read than lte discovery IMO) would be only way to tell.. If I recall correctly this device has 3g at 850,900,1800,1900 so there is no band 4 on 3g it seems... Although band 4 (1700/2100) COULD be a 3g band too for some devices. Someone with better knowledge can chime in here. I might be wrong.

[Xiaomi Mi MIX  Questions & Answers] krazyken04:
Update: I have actually successfully forced band twelve with NV values (I can see it stick and unwind the value to see that band 12 is allowed after a reboot). I followed about 10 diff guides to get my bearing on working with the Qualcomm editors and maintenance programs.

Sad to say: the modem in the Mix simply won't do band 12. I talked with a few folks from the Xiaomi Reddit Discord and they confirmed my suspicions that with Xiaomi (with a few exceptions) it is usually hardware that's keeping you off of a band.

I don't personally think there's any amount of software hackery we can do to get bands unlocked.

Edit: I am quite comfortable in ADB / SU and am happy to try any and all suggestions out on my phone in addition to what I've tried already btw. Please do let me know if there's something you think I may have missed following the various unlock threads.
[Xiaomi Mi MIX  Questions & Answers] mac231us:
Sorry to hear that the band could not be tapped into...

yes most likely a hardware thing-like Samsung (some of their models exclusively for Latin america have u.s bands but the 'international' variants of the same models will not do the U.S bands no matter what...

I actually opened one of them (got a damaged T239M) and found indeed that the motherboard is different...(so much speculation and folks asking/trying to flash S. American firmware on like the T705, T239 etc, myself included (not possible anyway even if going through TWRP and flashing modem files etc...bootloader and pit all different..so nothing would change with the other parts of the firmware)

so it is highly likely in this case that the modem will not do bands 12, 17 (ATT) and 29, 30 (ATT). However, it is impressive that for a China phone this will even do bands 2, 4 and 5. Huawei models (again supposedly international) except for some variants of the smaller 5-5.2 inch models (not p9, p8, P8 max, x2, t3, t3 pro, or m3 (some of these are the tablet phone types) and numerous other Chinese phones will not do anything more than 1, 3, 7 and then maybe 8 and 20 or a 28. (all useless for North America). Huawei has an M2 variant that has US bands and also on their smaller phones (certain versions)

so for the Mix, you at least have LTE 2, 4 and 5 (though of lesser importance).

[Xiaomi Mi MIX  Questions & Answers] krazyken04:
So far my experience is that if the band isn't listed in those spec sheet it isn't there in the hardware (apparently a very Xiaomi thing to do). I'm finding that they rarely software lock you out of the bands, it's usually that their hardware simply doesn't support the band.

[Xiaomi Mi MIX  Questions & Answers] emann56:
Here you go!

Step 1: Download The Following

1. Qualcomm Drivers

2. QPST 2.7.411 - https://mega.nz/#!lwVCgCKa!a5pLZFROgsAxnwxbvb6cNxRi-RpeN1JmnMFaEaj2jUk

3. QXDM 3.12.714 - https://mega.nz/#!g01DXJYJ!g-VzzF2_MXwE1LDExAzSJO-K14sdne7ymV9_OxAWLCk

Step 2: Qualcomm Diagnostics Setup

Connect the phone to computer with USB cable.

Boot the computer into the Disable Driver Signature Enforcement mode.

(Press Start->Search->cmd then right-click on it and click Run as administrator. In the CMD window type or copy this bcdedit /set testsigning on and press enter. Restart PC.)

On the phone keypad type *#*#717717#*#* to enable the diagnostics mode.

Open the Device Manager (Win+X, M).

Update the driver for Device Manager --> Ports (Com & LPT) --> Qualcomm HS-USB Diagnostics using the attached Mii5_Driver.

Step 3: Edit the NVRAM settings

Use the following Qualcomm software:

Qualcomm Product Support Tools (QPST)

Qualcomm Extensible Diagnostic Monitor (QXDM)

Open QPST Configuration first. Make sure there is an active phone there, and leave it running. Then, open QXDM as well and in Options ? Communications check the box next to the matching device and choose the matching COM port from the pull-down list below. Click OK and choose the NV Browser view to find the configs you need to edit.

You need to edit 2 configs: lte_bc_config (LTE) & rf_bc_config (GSM & WCDMA)

PLEASE MAKE A BACKUP OF THE VALUES BEFORE EDITING. WRITE IT ON A POST IT NOTE IF YOU NEED TOO.

LTE BANDS: Change the value of lte_bc_config to 2061719111903

This should enable - 1,2,3,4,5,7,8,12,17,20,28,38,39,40,41 bands. (If any bands don't work then I guess the hardware doesn't support it.)

GSM/WCDMA BANDS: Change the value of rf_bc_config to 562950069289863

This should enable - WCDMA 1,2,4,5,8 bands. (If any bands don't work then I guess the hardware doesn't support it.)

ALSO: If I am missing any bands, download this app and make your own values - https://play.google.com/store/apps/details?id=org.vndnguyen.nvcalc&hl=en
[Xiaomi Mi MIX  Questions & Answers] emann56:
Check the above post, I can't promise you it will work. I don't have service with band 12 to test it. If it doesn't work then the hardware just doesn't support it.

And you're certain how?

Could be nvram variables overwritten on boot. That's known to be the case on other Xiaomi phones.
[Xiaomi Mi MIX  Questions & Answers] mac231us:
that is just like this

http://xdaforums.com/galaxy-tab-s/development/wip-lte-bands-usa-t2875561

Samsung in its variants of its SM-T705, SM-T239, SM-T561, SM-T285 (don't know of more) has bands for all regions similar except for Latin America (705M, 239M, 561M and 285M). The S. American versions (M) have North American LTE bands 2, 4, 5 and 17 (not found on European, Asian, Oceania etc region phones) Folks have tried various things (myself included) to no fruition to get the U.S bands on the non-S. American versions...I actually opened a T239 and 239M (trashed device I got) and found the motherboards are actually different

So in the thread above you will see the similar issue...enabling bands in the service menu but they do not stick on reboot..(and anyway the hardware is not capable anyway as the communication chips whatever are different as are the boards)

Some have even tried to get the U.S versions that are marketed by ATT etc that do not have cellular calling to somehow do the calling-not possible becasue again the hardware is different (at a minimum, speaker and microphone arrangement is different as the U.S versions are tablets only and not tablet phones)
[Xiaomi Mi MIX  Questions & Answers] thklinge:
That's different. Look to the other Xiaomi phones. Some can be reprogrammed, others don't because the nvram values are overwritten by software on boot.

The hardware in this case is the Snapdragon 821. It's an SoC, which is an abbreviation for System on Chip. Which means that all the bits you need are included inside a single chip. Do you really think Xiaomi modifies the Snapdragon chip to disable radio bands?

This is all software, I'm confident a workaround is technically possible, but might require boot time modifications.
[Xiaomi Mi MIX  Questions & Answers] mac231us:
the Sm-t285M also has an SoC (as do the T239 and T239M),..even if not even half as sophisticated...it integrates radio modules ...and is the same as on the SM-T285 (have both devices) yet one gets U.S frequencies the other does not (even has different bootloader and pit)...

About Xiaomi...don't know...one may ask the same about Samsung..why? like why would Xiaomi stop at bands LTE 2, 4 and 5 and not do the 17? or the 29 or the 30..or the 12

there must be something else other than the software imo

anyway some bright folks will figure this out hopefully one way or the other! hope they can get the bands
[Xiaomi Mi MIX  Questions & Answers] thklinge:
It's for the Chinese market, so during boot time they set nvram values to enable only the relevant bands. Nothing more to it.
[Xiaomi Mi MIX  Questions & Answers] chris.davis925:
I think this is often the case. I suspect it has a lot to do with the FCC for American markets. The FCC must approve the bands and frequencies for devices selling in the US.

In any event, I think [MENTION=3850697]Goronok[/MENTION] can tell us if it works or not once he tries it today. :)

I have observed that some roms/kernels are applying their own values at boot - in which case we should also attempt to use a different kernel or ROM if possible. I don't (yet) have this device.
