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.....
I have an x720 and have been reading on how to unlock band 17 and 12 for at&t and t-mobile LTE service. As of right now I have some limited LTE service on band 2 and 4 (at&T) but it leaves much to be desired.
I see everyone here flashing the x720 firmware to get their x727 bootloader unlocked and then flashing back to the USA Firmware to get their LTE bands back. Is the reverse possible for the x720? Can I flash the USA firmware to get the LTE bands? Will this re-lock my bootloader?
I tried flashing the modem fix from https://forum.xda-developers.com/le-pro3/how-to/flashing-guide-roundup-leeco-le-pro-3-t3511901 on my x720 and now my sim card is being detected even after a wipe and reflashing my rom. So I'm assuming i'm gonna have to go back to stock firmware anyway. I've been a long time flashoholic and modder and I'm dedicated to getting this to work for us x720 people in the US.
What about this guide for the le max 2? I've heard all qualcomm devices can benefit from this procedure:
https://forum.xda-developers.com/le-max-2/how-to/guide-unlock-bands-leeco-le-max-2-fix-t3439154
UPDATE: Fixed no sim error after flashing x727 modem.
Downloaded a stock version of the Chinese Firmware and extracted the zip, then booted into fastboot and flashed the modem. You need the NON-HLOS.bin file. Then run "fastboot flash modem NON-HLOS.bin" and reboot! Voila. But still no band 17
I think unlocking the bands is not as easy as just flashing a ROM. When I was investigating OnePlus 3T, there is a long thread about it and basically band unlocking requires a lot of tools, some from Qualcomm and not easy to get, and a process that is not for noobs, not even for "professional TWRP flashers" but hardware-engineering-mode noobs anyway.
You can have a look here on how complicated it is (OP3T forum):
https://forum.xda-developers.com/oneplus-3/how-to/guide-unlock-additional-lte-bands-t3519563
Initially I liked OnePlus3T more because of optical stabilizer in camera, but lack of bands (or better to say, their separation into North American and European version) was a no-go for me. I need bands 2, 3, 4 & 20 and there is not a from-factory OP3T with those 4 bands in one device. Band unlocking might be possible but I would not risk messing with a $450 hone to get bands 3 & 20 unlocked on NA version. So I went with Le Pro 3 X720 and I am a happy camper.
So unless you know what you are doing, or are an adrenaline junkie, I would not mess with band unlocking.
I would absolutely LOVE to see an answer and/or progress on this EXACT scenario being made. Both myself and my wife have Le Pro 3's because of the universal network band support and INSANE performance of this phone (I've literally never seen such a performer with such large battery AND ridiculous band support at such a cost effective price) ((I bought both for $249 each).
I would LOVE to be able to buy the Chinese version with the 6G of ram, and then unlock the NA bands, specifically and especially bands 2,4,12,17,and 20 would be needed for our phones. So I'm super interested in this. You want to do exactly what I'd like to do, although you have the Chinese phone in your hand and I don't.
Both of our phones (x727) are bootloader unlocked, rooted, and TWRP recovery installed on stock .21S done by myself. So if there's anything I can help with, let me know.
Are you rooted? Download Network Signal Guru and lock bands under the menu in the top-right. See what LTE bands are listed there.

Yeah I've read through that process before I posted. I don't know if I'd call that "hardware-engineering" just because it puts a device into serial mode and communicates with NV memory.... I used qualcomm's boarddiag tool to unbrick a nexus 5 with the serial connection... doesn't seem any different at all actually :fingers-crossed:
I'm not ruling that out as a method, however I think we may have hope to do it easier. The x727 has been many times on this forum successfully flashed to x720 firmware. Everyone who did this reports the loss of usa bands though i have not seen confirmation that they GAIN additional chinese bands. That indicated to me that the baseband/modem is the only difference between the x727 having band 12 and the x720 not having it. We just need to tweak the x720 modem with the bits from the x727 modem.
https://forum.xda-developers.com/le-pro3/how-to/flashing-guide-roundup-leeco-le-pro-3-t3511901 In this thread there are several users that say they successfully flashed their x720 with x727 firmware and had full LTE, however there are also users reporting flashing the x727 firmware gives them a "no sim card detected". The latter was my experience. I believe this has to do with the switch from dual sim cards to single sim cards, i tried several build.prop tweaks to try and resolve with no luck.

From my x720: 1, 2, 3, 4, 5 ,7, 8, 20, 38, 39, 40, 41
I think that's what is officially listed online. Most people in the US would be fine with this except the notable lack of band 12(tmobile) and 17(at&t).

Then let's get started! Looks like all we are missing from your list is band 12 and 17.
Can you get me a dump of the baseband? I'd like to start digging into it and compare the x720 and x727.
I may try the qualcomm tools if I get the chance this weekend. If I have success and don't brick my phone I'll do a write up specifically for the LP3...

Sure man, I'm totally down to help however I can. I've never dumped a baseband before (never had the need) so the process eludes me, but I'm more than happy to perform whatever steps needed to do so.
Just give me a detailed rundown on how to do it or what tools/commands to run and I'll have it done for you ASAP. You can privately message me if you'd like, makes no difference to me. Give me the knowledge and I'll give you the love.

Question, how do I unlock the bootloader now? With the us servers down I can't get twrp files. Also, I can't unlock the bootloader with adb. I'm trying to flash Lineage OS onto my x727. All help is appreciated, thanks.

Had anyone who doesnt have the Global Version tried to change the LTE Band with the Snapdragon software tools? If you haven't heard or tried this just search Unlock LTE Bands in XDA main search. Because I'm think its going to be much cheaper to by the Chinese version that is like only 343USD for 6gb of RAM and 128 ROM and unlock the bands. Any thoughts? Thanks.
Changing the bands with QPST or QXDM can be done but it has no effect on functionality.
Some software will see these bands as unlocked but the phone itself can not make use of them. You might also run into some trouble on MIUI though custom roms seem more flexible with this.
At the moment there is no way to convert a CN (band restricted) model into a Global model (no band restrictions).
Hi, somebody has any news ?
for conversion(activate ) band 20 in Xiaomi Note 2 ?
thank you
This is very important topic I think. What I find really weird that the firmware files (modem) and rom are the same no matter which version you have...
On redmi note 3, kate and kenzo have different rom and different modem files. Its really weird here.
Hello good people,
I live in the UK, where the V20 was not released.
I have bought the AT&T unlocked H910 from Ebay, as it was stating that it works in the UK,
but the LTE band used by my carrier 800 MHz band 20 is not available on this phone.
"LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 12(700), 29(700), 30(2300)"
I have followed some of the noob guides and reading for days I believe that I have successfully rooted the phone, (shows in root checker). - as after some reading I was led to believe that by rooting the phone i would be able to change these settings via an app. however this did nothing for me.
could someone please kindly point me in the direction so that I can mod this so that the phone picks up and communicates with the correct Band? is this possible at all? or should i just try to return this to stock and return the phone?
or is this a situation where i just bought myself a small tablet?
I would be grateful for any help in solving this issue,
Many thanks in advance ! :good:

or is this a situation where i just bought myself a small tablet?
I would be grateful for any help in solving this issue,
Many thanks in advance ! :good:

Hi
You need to get into the service menu on the 910 and search for the 20 band and enable it. Sorry I cannot be more specific. You can google for the code(s) that will get you into the service menu.
I have a V20 but it is Verizon vs995 which has the correct bands but for some reason will not work with EE 4G only 3G.

Thank you for your reply,
I have tried this, i think i can get in by code *#546368#*910# assuming that this is what you are talking about?
this will take me to hiddenmenu
with 4 sub menues
- device test
- ELT Test
- SVC Test
- Field Test
I believe that i've seen people try to access the modem settings in the field test option
and i have seen that people get 3 or more options in this place, (third allowing you to select band) where as I only get 2
- Engineering mode
- PDP settings
do you know why the option does not appear for me?
- Would there be a chance that the option was hidden from the start by AT&T ?
Also I did not do LGUP dump before the root where many people in their guides have pointed out to
do, i followed a guide which does not involve LGUP to attempt to root my phone, should I try to flash the phone in a different firmware to try to unlock the mode ? along with the LGUP dump ?
again, thanks for the response !
Sorry, don't know but have you tried SVC entry I seem to remember some in the US using that to alter their Band.
The code you used does not work for me on my V20 in fact apart from IMEI code *#06# no codes work o. My phone.

Hi thanks again for getting back to me,
I am sorry but i do not know what SVC entry is, any relating articles i find are about terminal entry? is this in the ball park ?
could you point me in the direction of where i may find the information to do this myself ?
Ty
I meant SVC Test entry. Other than that I do not know. Sorry.
Hi Stransky,
Did you ever get your h910 to work in the UK? I think I have the same issue with my V20 h910

If you are in the UK then you don't need H910 rom. Flash it with US996 [usa] KDZ and that will sort out all the band issues without having to do anything more. Plus get's rid of At&T bloatware as US996 doesn't have any carrier bloat or network restrictions. I'm in Ireland and the rom is working great, 4G+ etc. My phone was originally a Verizon model.
edit: One drawback is you will loose FM radio as it's not on the US996 rom. If you are able to root the fone you can get it back with my mod if your on oreo.
thanks don't want to use the FM radio so will try your mod. Is there a guide to flash US996?
I'm being told in another thread that flashing another rom can't give you extra bands, so I'm a little confused between the contradictory advice.
ROMs do not have anything to do with available bands. Bands are hardware dependant

Your answer is in bold. He just gave bad advice. If you look earlier in the thread the Verizon variant has those bands already.

You can buy a US996 v20 on eBay for $86 with free shipping in the US. Probably your best bet. V30 and G7 unlocked phones aren't too expensive either in good condition, though I have not cross referenced which bands they have, so you'd have to double check. I like the phone myself, might buy a couple so relatives have backup phones.
Let me be clear. The H910, VS995, US996, on a hardware level have exactly the same motherboard, The only difference is the software...the ROM. So for example VS995, US996 don't have FM radio out of the box where H910 does. This is a perfect example of where the sofware has been designed to restricted FM radio leading one to *think* the fone doesn't have FM radio on some models at all but in fact it does.
So, It the same idea for BANDS. A fone MAY be missing bands out of the box because the ROM has been designed to restrict some of the the bands where in reality the fone has those bands. So in that case you can overcome this by changing to a ROM that does not have this restriction enabled in the ROM, in exactly the same way as in the case of FM radio. Carriers do disable bands on fones for their own devious reasons.
I know from experience H910 has hotspot restrictions as well. There is a work around OR you can just flash US996 that does not have this hotspot restriction. Also H910 has restriction in the Mobile Settings section. If you change to US996 there will be extra settings in Mobile networks>System Select settings which are GLOBAL / LTE/CDMA, LTE/GSM/UMTS. These options I'm sure I recall did not show up on H910 rom which could be useful to some.
I did not have an original H910 but all I'm saying is that I'm fairly sure that the motherboard is exactly the same as the other models in which case it will have all the same bands as Verizon and US996, just you can't see them because of H910 software on it. Of course you can't enable bands if they don't exist on the motherboard but you can if they do exist but have been restricted by the ROM.
So to the guy who asked about the H910 you can try to use the service menu to enable bands BUT this is not the best way to do it as the service menu might not let you or maybe the enable doesn't last after rebooting. The best way to fix this is to flash a ROM that does not have network restrictions and then you can forget out it from there on in.

Please see my previous post.
You have 2 options. You can either flash a clean US996 KDZ that you download at https://lg-firmwares.com. You'd need LGUP to flash it, guides on youtube and here, search for them. You don't have to be rooted to flash a new KDZ.
If you are rooted you can just download a custom ROM from here such as WETA ROM US996santa version and flash it in TWRP. You could backup your current system just in case it doesn't solve your problem but even if your problem isn't solved the US996 rom would be better anyway for the other reasons I mentioned in my previous post plus I forgot to add that would get rid of all the AT&T bloatware as well.
thanks for the advice, I'm really struggling to find a guide that matched my requirements or is there a generic guide I can follow. Bit scared as I'm reading some roms will brick the device.
Don't need to root at the moment so hopefully that will make it simpler.

Hi there - can you please point me to the rom you use? I just got a H910 from ebay at&t 'unlocked'. But I found only 2g on the stock rom. Have flashed a variety of U996, H915 (canada), and a H910pr (puerto rico) but can only get 3g sometimes. Some of the android 7 roms don't even have 4g as one of the options. Others do but I cannot select it - only 3g.
I'm in the UK but the 800/1800 bands Ireland uses are also the same for EE in the Uk.
Many thanks!
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.
