Recently with the delay on 5.0 for the US LTE variant, because of AT&T, I have lost my patience with them. I am looking for a way to rid myself of this BS while maintaining full stock software. I have heard that the variants of the tablet are actually not different, and the firmwares may work on either model. Has anyone tried this? I'm well aware the cell bands supported may change (but my carrier only requires one band, and the WW variant supports one of my carrier's bands). I would love to know if it works, and if I can dirty flash the package to keep my data, since the rom is basically identical.
I flashed OTA posted in general forum for LTE and using it in ATT. Unlocked bootloader, CWM, and root afterwards. I'm not quite sure what you're looking for?

Bricks.
No what i'm asking is if i could convert my device to the WW variant with a firmware flash, and thus avoid needing to manually flash OTA files becauze of delays. I know this isn't going to be the last update delayed on the US variant so i'm wondering if i can just switch the installed software from the US LTE version to the WW LTE version, without bricking.
Yeah.. I am thinking the same thing as well.
If it was possible without bricking the device, I would love to flash the "Rest of the World" firmware on the AT&T set too.

You're welcome to try it with the factory images. If it does brick, you can always restore through the same process. I plan on attempting it soon, but i am waiting on a microsd card.

Theoretically, the only thing that would be changed between builds is the GSM stack. However the OTA between the WW and the US version would not work by default. You'd need to go into the OTA zip and mess around with some of the build.prop info. Which then may cause MD5 mismatches when it is parsed, and would definitely affect subsequent OTA updates because of MD5 mismatches.
If there are Android 5.0 factory images available for the WW ROM you feel would be suitable for your geography, then this would be the safer way to proceed.
I remember when I owned a Samsung Galaxy S2, there was an XDA thread with flashable modems you could push to your device to get better reception in your area. Essentially the differences between the WW and US/CAN versions should only be the GSM stack, and perhaps some carrier-specific bundled app (like the AT&T app for example).
Just a quick update for those who are interested:
Well ... I just did it. Successfully flashed the RoW recovery image on the Shield Tablet LTE set which I purchased from US via Ebay. I'm still in the process of restoring but so far everything seems to be working fine.
Confirmed 2 things during the flashing of recovery image,
Quote:
1) Issues of Cellular/Sim Card on the US LTE set is almost certainly Lollipop firmware related. No problems on FW 4.4.2
2) Problem of Wi-Fi authentication error after sharing files via Super Beam ( Wi-Fi direct ) is also resolved after revert to 4.4.2
I think I will be sticking with 4.4.2 for now with the added bonus of file managers working on Kit Kat.

Thanks for the update. I am interested in this also.
So i'm assuming from your post you got LTE working? Which country are you in? Where do you get the factory images from?
I live in Australia and have the US LTE version. HSPA+ is good but it would be nice to have LTE working on my network (Telstra).

Actually, I don't have a 4G LTE micro sim card with me so I can't verify that at the moment. I am trying to test it out using my friend's sim card and will report back with the results. In my opinion, it's not a good idea to be trying my nano sim on this.
I'm from Singapore and the network I'm on supports LTE Band 3 & 7 and my AT&T Moto X which supports Band 7 works out of the box.
Got them from Nvidia developers website but you have to register for a free account first.

Yep I need LTE band 3 for my network which is not supported out of the box by my US LTE shield. If your network supports LTE Band 7 then your shield should also be able to access your LTE network as BOTH the US and RoW LTE shields support LTE Band 7.
So I don't think your experiment will help me. Is there any way finding out which LTE Bands your shield supports now that you have flashed the RoW recovery image?

I am not really an expert on such matters but let me try and if it's possible to find out the information you are looking for.
Why not try flashing it and give it a go ? There's the bonus perk of removing the AT&T app from the device.

Hi, I am currently using US LTE NVIDIA Shield Tablet in Singapore as well. I have successfully flashed the RoW recovery image to my tablet (since I'm downgrading from Lollipop as well, so I thought I might as well try), but I noticed that there is no baseband file in the recovery image package. I proceeded to flash anyway.
One thing I noticed after flashing is that I still am not getting LTE (half of Singapore is band 3, and my home is under its coverage). So, it's pretty safe to say that the baseband is not affected by the factory image.
However, it might also be that the latest recovery image doesn't cover the baseband, and it might be included in the previous updates. So, I'm trying to download the previous recovery images and see whether there are baseband images are there.
EDIT: baseband image is not in there. The baseband version is definitely still for North America (e1729-nala.4.05_0.6.3 @786934, notice the 'na' part?).

Sorry I don't really understand ... the RoW software cover for both Band 3 and 7 since the UK edition supports these LTE bands as specified in Nvidia FAQ.
You should still be able to get Band 7 coverage which the NA edition supports as well, right ?
Am I missing something ?

Thank you. That is exactly the information I was looking for. Unfortunately there is no point flashing the RoW recovery image if you wish to change your baseband (and then use different LTE bands like I want to).
Is there anywhere I can download the RoW baseband images? I remember they were readily available for my nexus 4.

As I said, the image doesn't include the baseband image. So, no matter what you flash on the rom side, it won't matter.
Also, about band coverage in Singapore, it's not a full overlap. Some areas are band 3 (south and west), while some band 7 (North and East). I know this from an M1 engineer friend. So, yeah, no LTE band 3 in this factory image here.
But not all hope is lost. If one day Nvidia decides to update baseband, it will then definitely include the baseband in the OTA or factory image. So, possibility of switching is still there.
Was there a baseband update with the latest software update (2.0)?
The factory images for 2.0 have still not been released.
In another strange twist when i turned on my tablet this morning I was surprised to see my US shield had LTE here in Australia. Which means only one thing - Telstra are expanding their LTE spectrum in my area!

I downloaded the OTA manually and checked the content. It doesn't have any baseband update. Also, just to confirm again, I actually re-installed Lollipop. The baseband is still unchanged (only the suffix @ part changed, but I think it's just some marker).
I checked wikipedia, and it seems that Telstra has band 3 and 28. There's a good chance that they switched your area's band to 3, or they simply add band 7 (the latter is, of course, ideal).
I read that Nvidia is preparing an update to the existing Lollipop system. Hopefully they will include a baseband update, then we can probably make the jump to the RoW ROM. For now, I'm sticking with the US ROM first.

Okay ... I see that you are not able to get Band 3 coverage. But just to confirm, you are still able to get band 7 4G LTE coverage on the ROW Rom right ?
My phone 4G LTE is on Singtel, getting pretty good coverage island wide on Band 7. Unfortunately, it's a nano sim and I'm hesitant to test it on the tablet in case in gets jammed inside the slot.
So long everything works fine, I'm sticking with ROW Rom as it will probably not have none of the nonsense whereby it require AT&T approval before release.
Sorry to trouble you on another matter, I have reported this 2 issues to Nvidia customer support but just want to check if it's just my set or an common problem.
1) Cellular data connectivity will not return after enable aeroplane mode. SIM card is subsequently not detected.
2) After sharing files using Wi-Fi direct ( SuperBeam app ), Wi-Fi connection doesn't auto reconnect due to failed authentication. Require manual intervention.
What I can say is this 2 issues no longer occur once I downgraded the software from Android 5.0 back to Kit Kat 4.4.2

According to Nvidia faq, the North American version that works on AT&T, T-Mobile and Rogers on LTE bands 2, 4, 5, 7, and 17 and HSPA bands 1, 2, 4, 5.
I see that this article ( http://www.cnet.com/au/news/telstra-expands-its-4g-services-including-the-700mhz-band-trials/ ) states that Telstra is conducting trials for 700mhz (Band 17) in your area. Maybe this is why you have begun receiving 4G LTE reception in your area ?

I initially thought it may have been the planned 700mHz expansion by Telstra in my area HOWEVER Telstra's 700mHz expansion is actually Band 28 (not Band 17) and my US shield does not work on Band 28 out of the box. Although LTE Band 17 and 28 both use the 700mHz spectrum they both use different parts of that spectrum so are not compatible.
What I think has happened is there is some LTE Band 7 coverage in the middle of town here which is where I was when I got LTE coverage today. As I understand it Telstra has some limited LTE Band 7 coverage with most of the LTE network being Band 3........ so I'll still have to wait until I can flash a RoW baseband which will hopefully give me Band 3.....
Four things to note before proceeding...
1. This only works for users having vs985 model outside the US or not on verizon network.
2. I'm beginner im not responsible for any harm to your phone , I'm just sharing what i did to attain 4g services.
3. May be you already know all the things in the post but it can be useful for beginners like me .
4. Sorry for the english as its not my native language.
So Hi guys i installed this rom and as usually i was not getting any 4G or lte network.
Then i go to my network provider's website to check on which Band or frequency 4g services are active. ( for this i just googled 'idea 4g band' and i am redirected to my network provider's website. Here 'idea' is the name of network provider.)
So i found that in my region 4g services are active on Band3
Different careers use different Bands to provide 4g services such as band40 , band17 etc
Then i go to phone's hidden menu by the Advanced Menu of Fulmics Tweaks.
In hidden menu i select Modem Protocol > LTE Band Selection
There i select Band3 but i got "Fail' message on screen , however when i select band4 it gave me a 'success' message.
It means on my phone band4 is active but not band3.
All this information of Bands are stored in Modem or Bootstack section of our phone.
May be fulmics rom is having a band concerned with international rom So now i need a modem on which Band3 can be activated by going to hidden menu.
So i just flashed 35b Bootstack compiled by @xdabbeb.
Which can be found in this thread http://forum.xda-developers.com/verizon-lg-g3/development/xdabbeb-s-vs980-2-0-0-t3231279
After flashing when i tried to select band3 in hidden menu it gave a 'success' message . It means Band3 is activated on my phone. And now when i searched for all networks in Networks Menu of Phone Setting. I got my network listed and i successfully registered on it. And got 4G NETWORK.
So first of all you should know on which band your network is working and then try flashing different bootstacks on which your 4g Band can be activated.
Flashing wrong Bootstack can brick your phone
""Do not flash any bootstack above 35b. Custom roms are still not compatible with bootstacks above 35b""
You can try 24b , 12b. (But im sure only about 35b as i tried only this)
Again I'm not responsible for any harm to your phone. Use your mind and search thoroughly before taking any step.

Hi there, thanks for the info. What area are you in and where did you find what band you needed? I have tried numerous times with all the bootstacks and never had consistent 4G.
@mopartonyg
I'm in India and i just checked my career's website to know which band they are using. However in USA Verizon wireless uses Band12 as Primary Band and Band2 , Band4 as Secondary band to strengthen the signal in densely populated urban area. So if you are verizon user in USA band 12,4,2 must be activated. I can't say anything about consistency as it varies from place to place.
Actually Verizon uses band 13 for it's primary along with bands 4 and 2. Not having any luck getting data to work on Fulmics with this method. I select band 13 and band 4 (as band 2 is not in my area) yet even with that I still can't get data at all on Verizon with Fulmics.
same boat here... actually the only band I can get working is 4. I have to assume the design of the international rom with the band they are designed around, just don't play nice with our CDMA harware/modem partition. I would suspect that the international roms would require some engineering for them to really work properly. not sure if just porting them over and chaning settings is going to get the job done. perhaps someone more intelligent than I could share some light, but there certainly is a conflict with how these roms communicates across the CDMA bands in the US

One thing i noticed here... that only Verizon sim users are facing problem regarding 4G whereas other international users like me ( and some of my friends in China are free to select any network ). So may be verizon is creating restrictions as when i was on Stock vs985 verizon Rom ( unrooted) , i was not getting any official ota updates. It always says your software is up to date. But then i found a statement in Verizon's website that you will not get any official updates if you are not having verizon sim.
So verizon knows what Rom and what sim we are using.

A couple of good approaches to the issue. Although it needs to be noted 4G is directly related to the band on each carrier (VZW, TMO, etc) See Below
Carrier 4G LTE Bands Frequencies
Verizon Wireless 2, 4, 13 1900, 1700 f, 700 c
T-Mobile 2, 4, 12 1900, 1700 def, 700 a
Sprint 25, 26, 41 1900 g, 850, 2500
Europe 3, 7, 20 1800, 2600, 800
If a specific ROM cannot be set to the correct bands above, it would make sense to me that Verizon wouldn't work in Europe on a stock VZW ROM. It would not be able to use the channels in Europe.
And vice versa, that Verizon wouldn't work in the states on an international ROM in the US. Whether the Verizon SIM is blocking that band, or the design of the ROM, would be a better question for the developers.

Warid's approved devices will definitely work with Warid's LTE network. For our "Warid LTE Approved' devices please visit the "Warid's LTE devices" section. You can also purchase LTE devices that support 1800 MHz (FDD-LTE Bands 3) from other sources. However, Warid doesn't take responsibility for these devices if they do not work on Warid's LTE network http://www.waridtel.com/lte/faqs
So it makes sense that if BAND 3 works international (see above) that you get 4G
The one thing I noticed after activating bands 13 and 4 (with the proper VS985 35B bootstack) in the hidden settings is when I searched for my network under network settings it does bring up Verizon but it fails authentication. So it's like there is something missing in Fulmics ROM itself that would get it to where the ROM will work with Verizon's network. So is it a matter of lifting whatever files from say 47A/47B into Fulmics that have the Verizon VS985 specific info to get it to work perhaps?

I think now its not a matter of bootstack. Because even when Required Band is activated we can't register to the Verizon. Xpirt mentioned in a post that he is working to resolve network issues in Verizon models. We can hope that this problem will be solved in next version However xdabbeb shared that the 47A modem won't work without the corresponding 47A secondary bootloader (sbl1). Unfortunately, the 47A sbl1 doesn't play nice with the last bump-exploitable Android bootloader (aboot) we have from 12b. If you use that pairing, you'll put your device into 9008 bulk mode(Hard brick).

The good news is we do have 47A ROMs that are using the 35B modem so there is potential that Xpirt could use that as a source for a fix with the authentication issue. So @xpirt if you need anyone to beta test fixes my VS985 is ready to help!

This is good to hear and I second that!
Looking forward to getting it fixed and use it as my daily driver. It would totally be worth a big donation, thanks to everyone working on making this available to so many.
Great discussion towards the development of the International ROM's for our VS985. I was able to get 4G with Andy's 30A ported ROM...although the signal bars never came up on my phone, I was able to get the 4G speeds. I noticed that the APN XML was filled with Chinese... So for whatever reason and way, my phone was able to grab "somebody's" 4G tower. I'm hoping the RIL (Radio Interface Layer) and libraries were pulled over and perhaps this could provide some more insight to @Xspirit

I am on BlackSoulxxx latest LG G3 Tekcafe v5.3 D85530A-Full G5 ROM. Here's what I did to get the bars with 4g data. I tested it out in areas where there is no cell service and in areas where there is 1x or 3g and the 4g came back. I even made a backup of the ROM wiped and installed another marshmallow aosp rom and others. I then went to restore BlackSoulxxx ROM and 4g signal still came back.
Steps I did.
1. Tot'd back to stock 10b and rooted and installed twrp.
2. Flashed LG_G3_Flash2BackupEFS.zip of the 10b rom.
3. Wiped stock 10b and flashed the 10b G3_EFS_Flashable_Restore.zip that was created from the the LG_G3_Flash2BackupEFS.zip.
4. Flashed BlackSoulxxx rom and after it booted up I had signals but not data until I entered the Verizon APN manually see picture of what to enter. If mobile network is greyed out flash 35b bootstack.
5. I entered the verizon APN and selected CDMA then global I got the 4g icon with signal bars I changed the icon with a buildprop edit.
I just don't get signals while in 1x or 3g but data does work still and it will get 4g again if your in a 4g area. The phone does say T-CDMA 64. Here's a https://drive.google.com/file/d/0B-EyVOQK1xDAa0VmbERXcUlrV1U/view?usp=sharing to change it to Verizon Wireless courtesy of @xpirt.

Great job posting your step by step instructions. I've been able to achieve all of the same on a host of international ROMS however with a couple of caveots. I can either have SMS/MMS working properly, or break SMS/MMS and have internet with signal bars. Question about the file above. This will just modify the header, or will it specifically put you on the Verizon network?

So when you go into the About Phone>Network, does it say Verizon Wireless for the network?
Pre-requisites: Must be 6045i user in an area that has band 12 lte (t-mobile) willing to flash a test hybrid modem/radio. If it doesn't work you just flash back your old modem. I have a version but am unable to test since band 12 is not in my area. I am attempting to combine the band 12 portion with parts of the 6.0.1 modem. Some issues encountered by users are apparently because they are using the 5.0.2 radio.
If you meet all the requirements and are willing to test please PM me.
Who's gonna test this 6.0.1 modem with band 12 support?
Come on...should I assume folks don't WANT to keep band 12? Eventually we will have to move to the newer modems to maintain compatibility with the roms. I've made a 6.0.1 radio that has the t-mobile config from 5.0.2. This radio works FINE on my personal phone for bands 2 and 4 but the closest band 12 is around 80 miles away. I've placed the test radio here under the "testing" folder: https://mega.nz/#F!u0UBAICD!DzKYnswfK5J6dw5WQNgEDg
ok, went and done did some tests.
with some interesting results...
--
note my starting point was the marionette's material rom. with 6.0.1 radios zip from famewolf's repository flashed over the top of the factory 5.0.2 radios.
i'm in southern california where Tmo has band 12, on a 6045i
--
questions:
1. are the radios supposed to be flashed right over the top of what was there, or is some partition supposed to be wiped first?
i flashed the radios each time right over the top of whatever was there, so if that was not correct, it would of course effect the results.
2. are we sure that the 6.0.1 radios do not have band 12 already available?
--
semi-related observation:
it appears that the lock screen issue of not being able to change the security method to anything other than none or swipe may be related to a temporary condition with the radio, rather than a permanent condition. as prior to testing this, i couldn't set pattern and so installed the 6.0.1 radios so i could set pattern, and then at the beginning of testing i installed the 5.0.2 radios and i still had the pattern lock screen functional. so the radio appears to only effect the actual act of changing the lockscreen, but doesn't have any other effect after the lockscreen has been set.
----
testing
-> i started with the 6.0.1 radios which i had already installed and LTE Discovery showed i was on band 4 at my office.
i didn't do anything else here because of the premise that i did not have band 12 available with the 6.0.1 radios.
-> i reinstalled the 5.0.2 radios, drove a short loop, and LTE discovery showed i was getting bands 4 and 12
as expected
-> i reinstalled the 6.0.1 radios, drove a short loop, and LTE discovery showed i was getting bands 4 and 12
i had reinstalled the 6.0.1 radios with the intention a little scientific method of documenting the lack of band 12 in the 6.0.1 radios, prior to the next step of testing famewolf's radio.
i do not know why, but i was getting band 12 after installing the original 6.0.1 radios.
this is why in my question above i ask if we were sure the 6.0.1 radios did not support band 12.
-> i installed famewolf's test 6.0.1 with band 12 radios, and drove a short loop, LTE discovery showed i was only getting band 4
so, this was also odd, as it was the opposite of what we were expecting.
-> i installed the original 6.0.1 radios and drove home, LTE discovery showing me going back and forth between bands 4 and 12 the entire drive.

It was widely reported that T-mobile was requiring manufacturers to remove band 12 in phones not fully compliant with VOLTE due to the possibility you could be somewhere where you could get ONLY band 12 and you would not have 911 access. Multiple people reported that the 6.0.1 radio stopped access to band 12. I provided a copy of the 5.0.2 radio and several others reported band 12 came back.
Now keep in mind I'm not in a band 12 area so I have 0 chance to test this myself. I took the t-mobile configuration file for the 5.0.2 radio and put it in the 6.0.1 radio...it's possible they also made additional changes I'd have to fix but I had to start with the simplest possible solution. Please take a couple of days to confirm your results. If you can't get band 12 on the hybrid then reconfirm you CAN on the plain 6.0.1. Please note the phone detecting the presence of a band 12 tower does NOT mean it's connecting to it...you need to actually SEE that you are connected to a band 12 tower in the lte discovery app.
Ok, more tests.
reloaded the 6.0.1 hybrid band 12 radios, and drove to work.
LTE Discovery reported my connecting to bands 4 and 12.
so, on a 30min / 20mile drive the hybrid radios will at least do the same as what the 6.0.1 original radios did last night.
both radios, 6.0.1 original and 6.0.1 hybrid, will connect me to bands 4 and 12 on the same commute route.
Is it posible to have band 3 enable in 6045i?

I just flashed the stock Oreo G935UUEU4CRG2 firmware (Vzw) today. I will run it bone stock for a week and report back. I should be able to tell if there's a significant difference in battery life and performance from the stock V firmware because I've never rooted my S7 edge and have run the stock Verizon firmware since new. With this Oreo U firmware, I do hate how Samsung Pay has that quick launch edge feature at the bottom of the homescreen that can't be removed.
I am very interested in the U version of the firmware . I have the Verizon Galaxy S7 Edge G935V w/ Android 8.0 but use it on Straight Talk with their AT&T sim card.
I had to change it from CDMA to GSM, also had to add a new APN for Straight talk.
It works but the phone is missing LTE bands 12 and 17. Band 17 is used in my area and without it the phone connects
to a different band and its weak in my area.
I am trying to learn if I can put the G935U (AT&T) firmware on the G935V and will I get band 17.
I know band 17 is in my area because of my previous phone of a week ago, Nexus 5.
Would you know if it can be done, and where would I find recent info how to do this
along with what bands and features would be offered or not available.
Thanks,
Ken

On my G935V, flashed with U Nougat firmware I have received the Oreo U upgrade.
It works great, the only issue is that it reverted the LTE bands to the typical V version bands. I had to re-activate the other LTE bands, just because... I can. My provider is still a Verizon MVNO, and VoLTE is working.
What I like about the Oreo is the Bluetooth codecs - besides the aptX and Samsung HD (UHQ) now Google provided native support for LDAC (Sony). I couldn't wait to get that, because I really wanted my Sony's MDR-1ABT headphones to be used in their full glory (LDAC codec).
PS: To appreciate the quality difference you need to listen to FLAC files.

Ken, first check out the supported bands between the Verizon and the AT&T S7 edge in the link below. It will confirm the discrepancy in supported bands between the two models.
https://www.phonemore.com/compare/p...5v-vs-samsung-galaxy-s7-edge-sm-g935a/3296028
Then go to this link and download, extract and Odin flash the AT&T "U" firmware and see if that will open up the AT&T bands for your Verizon S7 edge. It very well might. I think you should also choose the option in Odin to "Clear EFS" before you flash so that it can be rewritten fresh upon bootup with your AT&T sim card. Do this and report back your results. Good luck.
https://updato.com/firmware-archive-select-model?record=0A1AF06A906411E89F15FA163EE8F90B
Thank you for your reply.
I am downloading the firmware G935U (AT&T) firmware now. Its going to take several hours because I am not a member of that download site.
I did he A/B comparison and both phones seem to be identical except for the band coverage. The AT&T has band 12 which from my reading
is 700MHz and it includes the segment band 17 has so if I understand it right if I have band 12 I should be in good shape.
It also seems to have all the bands of the 935V except for band 13. The 935A has actually more bands of coverage.
Could you clear something up for me. Once I do this I am reading I can't go back to the Version S7 Edge G935V.
However would I be able to convert it to one of the other carriers like T-mobile ?
You are the first that stated to check the EFS box.
With ODIN I will be choosing all 4 files but making sure I do NOT choose the HOME file, is that correct?
After flashing are there any other special instructions I need to do or will the phone right after flashing just
need to go through the normal setup along with possible adding the same APN config I am using with it on Straight talk w/ the straight talk AT&T sim?
thank you,
Ken

Yes you can go back to the stock verizon firmware.
There's two csc files in the firmware pack CSC_HOME will not wipe everything and the regular CSC wipes everything. You need to choose the regular CSC so it wipes everything. So backup your internal storage if needed. You may or may not need to manually enter your straight talk APN. Your SIM and APN should be detected upon first boot. Just make sure you choose the regular CSC file and not the CSC_HOME. You want to wipe everything and start fresh. If your APN doesn't automatically populate after flashing the rom then enter it manually. You should have no problems with this version of the U firmware.
G935V to G935U (AT&T)
If its written I have not found it yet but it would be nice to have a before and after as far as what you will gain and what you will loose after the firmware flash. It would cut down
on all the follow up questions, especially for me.
After flashing, you said I can return to stock firmware. Its strange I am reading you cannot return due to a BL that will not be compatible anymore with the Verizon firmware.
The G935V has been taking updates when it was on Verizon. Will this continue after changing it from a G935V (Verizon) to a G935U (AT&T) while on Straight Talk with their AT&T sim?
Does this G935U (AT&T) flash change any specific characteristics of the phone like its serial number and model #? I ask because the Samsung Smart Switch program besides
backing up your phone can also return it to stock (in case something corrupts it) and I am wondering if I give it the current serial# and model number G935V, will there be any problems since its model number firmware will be different.
I was advised when using ODIN under "Options" to check "Phone EFS Clear" . Does this still sound right. All other settings should stay as is.
Thank you,
Ken

Q: After flashing, you said I can return to stock firmware. Its strange I am reading you cannot return due to a BL that will not be compatible anymore with the Verizon firmware.
A: When you flash a different U.S. firmware it has a bootloader included in the firmware. They can be flashed between the different U.S. firmware with no issue. the only time you may not be able to flash a firmware and bootloader is when you attempt to "downgrade your firmware to an earlier version.
Q: The G935V has been taking updates when it was on Verizon. Will this continue after changing it from a G935V (Verizon) to a G935U (AT&T) while on Straight Talk with their AT&T sim?
A: Yes, but the updates may not come as often as the carrier version of the firmwares such as Verizon, sprint, T-Mobile or AT&T. But you will get updates. It seems the carrier firmware will bring more frequent security patch updates than the "U" firmware.
Q: Does this G935U (AT&T) flash change any specific characteristics of the phone like its serial number and model #? I ask because the Samsung Smart Switch program besides
backing up your phone can also return it to stock (in case something corrupts it) and I am wondering if I give it the current serial# and model number G935V, will there be any problems since its model number firmware will be different.
A: No. The model#, IMEI, etc will not be affected. Only the software version will be affected as well as carrier specific update compatibility will be lost due to the "U" firmware.
Q: I was advised when using ODIN under "Options" to check "Phone EFS Clear" . Does this still sound right. All other settings should stay as is.
A: Yes. If you are having issues with network configs, you can choose to wipe efs so that it will rebuild upon first boot of the new firmware. This is only recommended if you have issues connecting to the network. Otherwise don't do it.
Since I'm on a roll I have another quesiton,
I dd a side by side comparison on this site
https://www.phonemore.com/compare/p...5u-vs-samsung-galaxy-s7-edge-sm-g935a/5532054
The phone called G935U has several more bands than the 935A (AT&T). Would this be a different G935U flash as compared
to the G935U (AT&T) ? If so would that not be the firmware to go with? It covers CDMA as well as GSM with the extra GSM bands.
This would be very similar to my G935V which offers CDMA and GSM.
Do I have it right NO CDMA capabilities on the G935U (AT&T) firmware?
Thank you for your replies its been very helpful. Its been a mystery trying to find out
what features you end up with with G935U and if their is a non provider version like in the above link.
Thank you

G935U Product Code USC vs. G935U (AT&T
Last night I flashed my G935U. It took 3 tries with the 3rd working after switching to a different ODIN reversion.
The phone works fine, no issues except I am disappointed I lost all the CDMA capabilities should I want to try straight talk with a Verizon sim.
After I flashed the file from the updato.com site I searched and found another G935U with Product Code USC. USA
https://updato.com/firmware-archive-select-model?record=05B44581906411E89F15FA163EE8F90B
A little more research and I found this is the unbranded version (correct me if I am wrong) The unbranded version appears
to retain CDMA plus have more GSM bands than the G935U (AT&T)
Could anyone offer some details on this firmware and could I have flashed this instead of the G935U (AT&T) to have retained
the CDMA and get more GSM bands.
Thanks, Ken

Then go to this link and download, extract and Odin flash the AT&T "U" firmware and see if that will open up the AT&T bands for your Verizon S7 edge. It very well might. I think you should also choose the option in Odin to "Clear EFS" before you flash so that it can be rewritten fresh upon bootup with your AT&T sim card. Do this and report back your results. Good luck.

In my experience flashing another version will not add the bands. My case - I have flashed the "U" version on my "V" branded S7 Edge and the bands remained for Verizon. The modem firmware will read something that is flashed in the modem hardware and activate only those bands. There is a way to force other bands (see below).
More so, having the "U" Nougat, with modded LTE bands, I got the "U" Oreo upgrade from Samsung. After the upgrade to the "U" Oreo, the LTE bands reverted to the "V" ones (I had to re-enable them again).
I did "force" in the NV the new bands on my V using QPST and QXD professional Qualcomm tools, but since I don't really have a T-Mobile SIM I can't verify if the change works or it is something hardware (like RF amps) that is really missing.
How to: https://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
The stock value for the "V" hardware, in the NV cell #6828 is 4190. That corresponds to LTE bands 2,3,4,5,7,13 (check with the LTE calculator).
I have changed the value to 2062440470751 that corresponds to bands 1,2,3,4,5,7,8,12,13,20,25,26,29,30,38,39,40,41 (close to what U would have natively). Again, I couldn't test if the software change is sufficient for them to actually work, but I have a feeling it does not.
When I traveled recently to EU, I have used cellmapper to check the LTE bands. I never saw B20, even if, on the map of that country, B20 was available in that rural location. I had only 3G.
G935U vs G935U
I posted the wrong link
This is the one I have my question on
https://www.phonemore.com/compare/p...5u-vs-samsung-galaxy-s7-edge-sm-g935a/5532054
This compares a G935U vs. a G935A
To get to the chase, what firmware would I flash to get the features of the G935U (left picture)
I just flashed my phone with the G935U (AT&T) and although it works fine with no AT&T bloatware it is missing
some of the GSM bands of the G935U (Left picture) and all of the CDMA bands.
Thank you,
Ken
Like I said above, the different firmware does NOT change the LTE bands.
KenKK said:
Last night I flashed my G935U. It took 3 tries with the 3rd working after switching to a different ODIN reversion.
The phone works fine, no issues except I am disappointed I lost all the CDMA capabilities should I want to try straight talk with a Verizon sim.
After I flashed the file from the updato.com site I searched and found another G935U with Product Code USC. USA
https://updato.com/firmware-archive-select-model?record=05B44581906411E89F15FA163EE8F90B
A little more research and I found this is the unbranded version (correct me if I am wrong) The unbranded version appears
to retain CDMA plus have more GSM bands than the G935U (AT&T)
Could anyone offer some details on this firmware and could I have flashed this instead of the G935U (AT&T) to have retained
the CDMA and get more GSM bands.
Thanks, Ken

G935U with Product Code USC is the "U.S. Cellular" network. I believe the way it works is the software will use the installed SIM to configure the network compatibility mode that will be available in network settings. The true "U" model of the S7 edge will have hard coded support for whichever bands samsung determines for that model number. The different versions of the "U" firmware are specific for whichever carrier/network the phone will be used on. I'm not sure which firmware would allow both GSM and CDMA networks to function simultaneously, but there is an app in google Play store called "network mode" and you could give it a try and see if it will open up simultaneous GSM/CDMA support in your network settings. I do know that Sprint's firmware does have GSM and CDMA support and I'm familiar with that because I have had sprint for nearly 10 years and have a lot of experience with the samsung software as I've built several ROM's including port ROM's over the past few years. Try the Sprint "XAS" firmware. That's the global version.
I've been looking for a good, inexpensive phone my partner can use on AT&T, T-Mobile and Verizon and I was able to snatch an unlocked VS995 in excellent condition for $70--it just needs the battery replaced soon which I also ordered. The main downside to this model if you're using it on AT&T and T-Mobile is that it doesn't support Band 12 and 17, but I know the US Unlocked variant does. I just received the phone today. I've been searching on the forum for an answer into if this is possible with the VS995 variant and I've seen people say it is using an LG V20 version of LGUP, but haven't found anyone that's confirmed they've been able to do it on the Verizon and not the AT&T variant and the steps they took to do so.
I want to stay on the stock ROM so I'm not looking to root and install a custom one. Is it possible to convert from the VS995 firmware to US996 so I can gain band 12 and 17 while removing the Verizon bloatware and staying on the stock ROM/OS? If so, would anyone one of y'all be kind enough to post the link to a guide or article that details how to do so? I reset the phone to factory settings so thankfully don't have to do a backup. After doing this, is it still possible to receive OTA updates and, if so, are they gonna mess anything up like reverting the phone to stock firmware or the phone's unlocked status?
Thank y'all so much in advance.
I have a vs995 and I flashed it with US996_usa and working great. You need to download the us996 usa version (2.3GB KDZ) at lg-firmwares dot com and flash it with LGUP PATCHED. There is video on Youtube giving detailed instructions. You will be able to find all these easily via google. I don't know how any of this works with the various US carriers or bands as I'm in europe.

As far as I'm aware, cross-flashing firmware on the V20 won't give you any additional frequency bands unlike some other phones, so you're still limited to what the VS995 has from the beginning. From what I've read, US996 firmware works fine on Verizon except for a few features such as WiFi calling and video calling.
As for AT&T and T-Mobile, you won't get VoLTE or WiFi calling along with the missing LTE bands, so, depending on where you live, overall coverage could be significantly worse than having the H910 (AT&T) and H918 (T-Mobile) models, respectively. Not having VoLTE would be a problem if you were in an LTE-only area without roaming because then you'd have no way to make or receive phone calls.

Thank you for the info. Are you referring to this video? I'd watched it before but it's for flashing the stock ROM on a US996 variant and the links in the description don't work.

Hmm, where did you read that? From what I've read the hardware/modem in the VS995 and US996 version is the same and therefore the difference only comes down to the carrier firmware artificially disabling bands the device supports just like it is on many other smartphones. I could be wrong, but one way to find out would be to do it myself and then try to connect to a Band 12 or 17 tower.
WiFi calling and video calling I'm totally fine with not having. Never used or needed them. With AT&T and Cricket I've never not had service and with Metro the couple times I haven't had T-Mobile service roaming has kicked in and saved the day. Thank you for the info.

Here's some frequency band info for both the VS995 and US996:
VS995
US996
I'm pretty sure this is a hardware difference, and no firmware change will be able to add more band support unlike some other phones you may have heard about (such as recent U.S. models of Samsung phones). Otherwise, there would have been plenty of discussions and guides around here regarding this (and FWIW, I happen to own a US996, LS997, and H918).
As for LTE Band 12 on the T-Mobile network, only phones that are certified by T-Mobile will be able to access it (more info on compatible phones here). So even though a US996 has the hardware for connecting to Band 12, you wouldn't be able to use it since T-Mobile has blocked access to it and only allows it for the H918 model.
Based on all this, I would expect a VS995 to get LTE Bands 2, 4, and 5 on AT&T and T-Mobile. Of course, since you already have the phone, there's only one way to find out. Just make sure you carefully read the guides/procedures about using LGUP for cross-flashing, and absolutely stay away from any H918 firmware (it will instantly kill any V20 that is not an actual H918). Not sure if there even is a separate guide around here as it is usually mentioned in the initial steps of different rooting guides for each V20 model, but you can find the patched LGUP that ezzony mentioned in this thread (you may have to move the DLL file to a specific folder location for it to work properly).

Yes, but the Frequency Check website only looks at firmware differences, not the internal hardware. I decided to do some further digging and went to the source that tests these (the FCC) and found that the VS995 and US996 have the same ZNFVS995 FCC ID meaning they share the same internal hardware. Verizon just decided they wanted to be arseholes and cripple the phone's band support in their firmware so it wouldn't work to the best of its abilities on T-Mobile's and AT&T's network. Similarly, T-Mobile decided to also be arseholes by artificially limiting Band 12/VoLTE support to their own H918 model only. I hate that carriers are able to get away with this BS. It is incredibly anti-consumer and infuriating. If the hardware supports XYZ then it should be enabled and capable of taking advantage of it. The FCC tested Band 12/17 to work properly on these and says regarding the device's capabilities:
This device contains the following capabilities: 850/1900 CDMA (BC0, BC1), 850/1900 GSM/GPRS/EDGE, 850/1700/1900 WCDMA/HSPA, Multi-band LTE, 802.11b/g/n/ac WLAN, 802.11a/n/ac UNII, Bluetooth (1x, EDR, LE), NFC LTE Band 12 (698 - 716 MHz) overlaps the entire frequency range of LTE Band 17 (704 - 716 MHz). Therefore, test data provided in this report covers Band 17 as well as Band 12. LTE Band 25 (1850 - 1915 MHz) overlaps the entire frequency range of LTE Band 2 (1850 - 1910 MHz). Therefore, test data provided in this report covers Band 2 as well as Band 25. LTE Band 66 (1710 - 1780 MHz) overlaps the entire frequency range of LTE Band 4 (1710 - 1755 MHz). Therefore, test data provided in this report covers Band 4 as well as Band 66.

Seriously, f*ck both Verizon and T-Mobile. Thankfully I'm starting my Cricket/AT&T service in a week so I'll be able to test if it can pick up and use Band 12/17. You happen to know of any app or way to force/limit the device to only using one specific LTE band? Thank you so much for linking to that thread for flashing these using LGUP. I'll make sure to follow it and to download the US996 (US Unlocked, not US Cellular) firmware and post a small update on my findings. Thank you so much for all the info. Really appreciate it.

While I've never tried this, have a look at this old thread on LTE band selection from a hidden menu. The dialer code differs by model, so for a VS995 it would be *#546368#*995# and for a US996 *#546368#*996#. The code works for my US996 and H918 on Oreo but not for my LS997 on Nougat (for which there is a separate APK file to access the hidden menu). There are lots of submenus and items in there, so be sure not to accidentally change settings that you're not supposed to.

Hello
You crossflash with which android version 9 or 8
If android 9 whats the battery backup (good/bad)
Does the android 9 has a darkmode
Does it brings back or activate the FM radio ?
Thanks

Android 8.
I know Android 9 does not have FM radio because Android 9 is only available for the Korean variant (F800) and it never had FM in the first place.
