Hi, I just picked up a H990n with a crack screen for 20 quid: ) Impulse buy, but at that price I'd be a fool to turn it up.
Anyway, what's the deal with this model? Can it be dirtysanta'd and is it a dual sim?
I know I could research this but I'd rather just ask this time.
Thanks.
No need to search.
Here is all you need

The DS model is Dual Sim.
Have fun

As far as I know, every V20 model except the updated LS997 is rootable, so you should be fine. There is a separate DirtySanta guide for the H990 models on here, but for some reason, it's under the ROMs section. The H990N also has dual SIM + separate microSD card slots like the H990DS, just a few different LTE bands. There are single-SIM H990 variations, but I don't think the H990N has one. In my experience, GSMArena is terribly inaccurate when it comes to details of different regional models.

Yeah I'd imagine your right, I haven't heard about rooting issues with any model except the LS997.
So it sounds like the N is basically a DS with slightly different firmware but prolly exactly the same hardware. It would be a bit odd if the N is limited in frequency bands since it's a dual sim. Probably will work fine for me in my locality as it is.

I agree, I usually only use those generic phone sites for very general info like screen size. You are much more reliable C D

FWIW, here's a list of what might be all the bands for the H990N:
https://www.frequencycheck.com/models/vn2jk/lg-h990n-v20-dual-sim-td-lte?c_id=2513440
If this is correct, then it shares all the bands of the H990DS and has two more UMTS bands and two more LTE bands (17 and 26).

Oh yes, I'd forgotten about frequecycheck, I do find that reliable. And indeed yes, I have 100% compatibility in my locality. All good so, tks.

Is it possible or will it be possible to unlock LTE bands on the chinese version?
no
So it will never be possible then? I've seen threads were they have unlocked bands on phones like OPO, S5, G4

I think its possible. If you can change bands for quallcomm SOCs(Like OPO, One m7, m8). But I think we need guide for this.
I've read this time around the modem is a different SKU depending on what version of the phone you have so I do not think it will be possible.
Of course you can activate the software... But you don't have the hardware antena...

May I ask where have you read this? What's the source?
Does anyone have a list of the different variants of the V20 around the world?
All I can remember, F800 for South Korea

I am looking for Canada version model number has well as it's LTE coverage bands.
I am waiting for mine to arrive, model number H990D, which is released in Taiwan I believe.
Here's a table with all the different model numbers I found.
Can not post links yet just google "lg v20 h990d" and its the 2nd link from techwalls.
No one else has replied to this? Surely the info exists... I'm considering getting the V20, but I want to make sure I get a version that CAN be rooted. So far only H918 is the only one, right? And that's the T-Mobile variant, right? Sucks for us who live outside of America...
EDIT: Ok, this is a good resource: https://www.techwalls.com/lg-v20-model-numbers-differences/
Here are the different models so far...

Hello Guys!
Looking to upgrade my actual Smarthphone ( S6 EDGE G925A ) and return to LG. I Have had the G3 and I really liked it! after selling it I got the EDGE because neither the G4 or G5 where good enough in my opinion.
Now with the G6 things got a lot Better! I wanted the 64GB version with the limitations it had, searched a lot and found the H870DS which was perfect! it has almost every single band but of course it does not have the B2 1900Mhz LTE band!!! Which is the one I need!
Before buying it I browsed the web and many sites stated It had it but no! I had to buy it to find out that is not true.
So the question is:
What version of the G6 64GB has LTE B2 1900Mhz and 3G 850Mhz?
Thanks!
LGH870DS its Dual Sim and has the Quad-DAC too

Thats the version I have purchased but do not have the B2.
You should have checked wiki like I did when researching the G6 and V20. Most times info there is correct.

Hey guys I've had my Axon 7 for almost 2 years now, I am planning a trip to Tokyo for just over 2 weeks at the end of August and want to be able to get a sim in Japan and use my phone as normal. Now our Axon 7 u supports 3/4 of SoftBank lte bands and 2/3 of the other bands it needs. So this option doesn't seem too bad.
Now getting closer to my question.
International or us versions of the a7 all have the snapdragon 820 which contains the modem. This same chip is available around the world including Japan. So
Does the snapdragon 820 have different versions with different modems? Or is the software the reason only certain bands are available in different versions of the phone.
If the software decides which bands are available is it possible to edit it to unlock any bands I may want when I am in Tokyo this summer?
I am on unlocked bootloader twrp etc. and have used lineage os and other ROMs right now on a stock based room rooted
Any help and knowledge is appreciated. I googled around a bit and didn't find much on the subject
Simply having a chip that supports a band is not enough, it needs antennas that are properly modulated and shielded for that frequency.
Even if you were to patch the modem to enable a certain band, you would most likely not get reception at all or cause interference on other channels

I'm guessing you aren't too aquaintanced with custom ROMs and that kinda stuff for the axon 7. lemme explain.
There are 3 versions: A2017 (china), A2017G (Int'l, the one used in Japan i think), and A2017U (US). All of them have different modems.
The updates for each device all come with different NHLOS.bin files, which are the modem files. If you flash the U file on a G you won't have any signal. Sometimes you can even wipe out your IMEIs.
But why do you need LTE for a 2 week trip though? You'll get phone signal and data anyways...

I know all about the different versions of the phone, I've been around here for a while. My first question was simply if the 820 has different versions with different banded modems. After reading your reply I'm still not sure. Like I said I know about the different versions of the phone and the fact that they have different modem firmware. My question was hardware related, based on another guys reply it seems not likely it's there antenna that is the deciding factor in what bands can work as far as hardware is concerned which obviously means there is no possibility of unlocking any bands

What I mean is that installing different modem firmware basically makes the modem inoperable. hence, there are key differences between the models
I'm in Tokyo right now and get LTE on Docomo via band 3, which doesn't seem to be advertised anywhere. I was quite surprised! Speeds have been great!
Technically, it can work in Japan. It will get LTE in urban areas and a mix of LTE and HSPA+ elsewhere. From a practical point of view, the garbage radios in the Axon 7 are a serious problem if you're roaming. Hopping around on different bands and carriers causes the radio to constantly die, lose data, or lock onto the wrong cell tower. You'll have to cycle airplane mode frequently and you can't count on incoming calls/texts working.
I haven't had time to try LineageOS in Japan yet. It seems to have fewer radio problems so it might do OK.
Axon in Japan
Hey, I use a American Axon 7 in Japan with no issues, if you use any MVNO sim that uses NTT Docomo Network you should be fine, for example BicSim, IIJMio Travel sim etc.
Hi there. I live in Canada and use A2017G. How to switch it to USA bands and is it safe to do? Or should I wait for Oreo (seems like November)?
Thanks
I think you are stuck with whatever bands that are hardcoded into the G. Probably has something to do with the baseband/radio/modem. I did find an article on XDA awhile back that claims you can add bands to your phone, but it seemed mostly suited toward Samsung. In any case, it doesn't really matter, a G model should still receive a minimum of 4G with most US carriers, but maybe not LTE. I'd imagine Canadian carriers are similar. But I do have to wonder, you live in North America, so why buy a G. The U is the variant that is designed for this region. And U has better support, ROMs, etc.
Maybe you can just flash the A2017U modem

Maybe you can avoid suggesting things you clearly have no idea about.
While you're at it, why don't you flash a modem from another phone?

You can't add bands that the phone doesn't have. By changing the daughterboard of an A2017U to an A2017's, a guy simply lost all connectivity, plain and simple. Antenna stuff is hardware stuff.
Oreo won't really add bands either
@Choose an username...: I have read other topics on XDA that say you can use QPST/QFIL to add basebands, on almost any device that has a Qualcomm CPU. But I havent tried this myself. It may just be a matter of placebo, or people wanting to believe that it works, when really nothing may be changing. You could also brick your phone during the attempt, which is part of the reason I havent tried yet.
I think that all A7s have nearly the same hardware, including the same (hardware) modem/radio, but with different basebands enabled/disabled depending on which model you have. But I have no proof of this. I will leave this to people that are willing to deeply dissect the hardware.
And then there are the modem files you can flash, which vary according to your model. I am not sure what would happen if you attempt to flash a A2017G/A2017 modem on a A2017U (or any other combo). I think the worst you will face is a loss of Internet/text/phone calls.
When I first bought my A7 I was going to get the Chinese version from AliExpress, because it has more RAM, storage, and ForceTouch. But then I realized that it doesn't have most of the basebands that my carrier (T-Mobile) supports. And you never know where most of the AE sellers get the hardware, they could be stolen, preowned, whatever. I have bought numerous 'new' items there before, but they ranged in quality, ranging from brand new to fair condition. So I thought better of it and bought a new A2017U from NewEgg, complete with ZTE's Passport warranty and 3 years SquareTrade insurance. And I'm glad I did, since a few months ago I had to make use of that warranty to get my A7 unbricked from DFU, before the tool was available.
I think only differences between A7 models are in processor i.e. bands. There are variants in SD 820.

We're in the same boat... My carrier using AWS bands just like T-MO. A2017G was working perfectly fine maybe missing just one band on LTE. And recently new band was introduced - LTE band 13 (700mhz), which supposed to improve indoor reception - big issue for Axon 7 and AWS. They call it 'Extended Rabge LTE.
So A2017U has that band, but A2017G doesnt. My assumption was that both phones are sharing the same hardware and bands available are controlled by software.
I clicked some numbers and got into some engineering menu where I see choices: USA Bands, Cellular 800. So I picked USA and restarted.
EPIC FAIL!
I lost 3g AWS on SIM1! Only 4G present, which is actually working fine. Just imagine phone with perfect 4G connectivity internet is flying, but you cannot place a phone call... (My carrier - Freedom Mobile doesnt have 2G GSM). I tried to switch it back - no luck
Solution - I use SIM2.
Oreo
Just installed it no OTA had to use sd card. That actually fixed SIM1 band problem. It doesnt seem I have band 13 (that is what I wanted), but connectivity seems better and switching between 3g and 4g is very fast...
