[Q] D80220c - Canada - Mobile Data and LTE Selection

Hey everyone.
I bought my G2 from an online retailer. It's from Europe I believe (D80220C?).
Here's my issue:
When I try to activate LTE in my mobile data menu the only selection is "GSM / WCDMA Auto". Even further, when I install a custom ROM I get the selection for LTE but it does not enter the LTE network. And further again, when I enter the 3845#*802# menu and select "LTE only" from the 'Hidden Menu -> LTE-Only -> Modem Settings -> RAT Selection' menus, I lose my network connectivity completely.
I know my SIM card works because I have an Xperia Z2 and Samsung Galaxy S3 (d2lte) and they both enter the LTE network instantly.
I'm guessing that the problem has to do with the modem. Is it because it is a European device and has no LTE network support in Canada?
I have downloaded close to 10 different ROMs tonight and plan on finding one that suits me as well as try to find one that actually allows me to use the LTE network.
Thanks in advanced for anyone interested in helping me out with this issue.

Can anyone help me with this?

Flash the correct modem. I'm having a similar issue

This is impossible to answer without knowing who your network provider is. Some use different bands than others.

Virgin mobile. The bands are: 1700B4 2600B7, if they share the towers with Bell. My phone is capable of those bands.

Virgin Mobile, so basically Bell.

My guess is that it will be D803 HERE. If you have ROM on your device then check model name under settings->about phone. Should say D803, but it also may be wrong depending on the ROM you flashed.

Mine is the D802. I tried flashing a D803 Bell modem earlier today and that did not work. Had to restore EFS and restore ROM.
Edit: Pretty sure I just bricked my phone. Can't boot any rom now... this is ridiculous. I backed up my EFS and when I restore it does nothing.
Edit2: Nevermind, false alarm. That Bell modem is not going to work for me though. D802 doesn't like D803 basebands

Did you try D802 modem? If not then flash the D802 modems and see if you get a winner

That's the problem though. There is no Bell baseband for the D802, as the D802 is the Intl' phone
Is it possible to modify the baseband to include the frequencies of Bell's LTE network in Canada?

[4g fix] on Fulmics Rom for verizon VS985

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?

LG V20 H910 AT&T - 4G Band Issues

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:

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.

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.

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.

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.

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!

Cross Flash From VS995/Verizon Unlocked to US996/US Unlocked?

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.

How to unlock 4g bands for H910 in UK/Europe?

Hi there. I bought an 'unlocked' AT&T H910 LGV20 from ebay.
I thought would work in the UK as the phone hardware has compatible 4g bands that my provider (EE) uses.
The stock at&t firmware only allowed me to use 2g/Edge.
So I have flashed several other roms / kdz files using LGUP
( h910 Puerto Rico, H915 Canada, US996 unlocked US - variety of android 7 and android 8)
Some roms (particularly Android 7.0 Canada and Puerto Rico) work with 2g and 3g but there isn't even a 4G option in the base menus.
Some roms have global or allow you to select LTE/3Gpp but they don't allow me to get a 4g signal.
One even said 4g at the top but when I checked the connection in phone settings - about - it showed 3g (and this was consistent with the download speed too)
II only got videotron Canada to work. Bell and Rogers should have an overlapping 4g band but I got the CUST error on those roms.
I have tried going through service menu but all that can do is sometimes force a 3g signal from 2g
So what should I do?
1. I s there a rom with overlapping 4g bands that would work? Can I flash a HK rom onto H910?
2. Can I root the phone to unlock 4g bands?
Would this survive unrooting to allow me to access microsoft intune (for work email), banking and sports apps (which sometimes don't like root?)?
3. Would a custom rom work? Which do you recommend to keep as many features as possible eg remote control, camera, DAC?
Do they also work with microsoft intune, banking apps, sports apps etc?
I have followed a few of the posts out there but given the ebay seller I wonder if a few more people in Europe might have been tempted!
Thanks!

Hi
You need Band 20 (800) to use with EE UK and according to GSM Arena list of specs for the H910 that version of the V20 does not have it and I do not know if it can be added.

Thank you!
I was led to believe the H910 (same as H915 in Canada) supported all of EE's 4g bands.
But for sure, the carriers seem to have locked some out. But not having any luck with other roms either...
I cannot post the url but
frequencycheck . com
carrier-compatibility/wwW4hXP/lg-h910-v20-lte-a-h915/ee-everything-everywhere-united-kingdom
Compatibility - 3 out of 3 bands supported
100%
Interface Name Supported by device?
LTE B3 (1800 +) Yes
LTE B7 (2600) Yes
LTE B20 (800 DD) Yes

As I said in previous post the H910 does not support Band 20 (800) check GSM Arena site select LG V20 and then H910 and select LTE bands and you will see that Band 20 is missing. The H915 is not listed.

I have a similar issue, having bought an "unlocked" H910 and having only 2G. Is this the file name of the H915 kdz file you flashed to enable 3G: "H91510e_00_VTR_CA_OP_1205.kdz"?
Thanks.
