Greetings XDA,
After some research, I've determined it to be a distinct possibility that the OnePlus X (possibly others) have built in software limitations.
In a recent tear down of the device (http://www.myfixguide.com/manual/OnePlus-x-teardown/) it was found that the device contains these two components:
Qualcomm WCN3680 RF chip
Qualcomm WTR1625L RF chip
Here are my findings of each of these parts.
Qualcomm WCN3680 RF chip
https://www.qualcomm.com/news/relea...1ac-product-ecosystem-provide-end-end-gigabit
"the WCN3680 is a mobile 1x1 802.11ac combo Wi-Fi/Bluetooth/FM chip"
This article from Qualcomm states the the chip present in the OnePlus X supports wireless AC.
Qualcomm WTR1625L RF chip
https://www.qualcomm.com/news/relea...olution-enables-single-global-lte-design-next
"The WTR1625L can accommodate all cellular modes and 2G, 3G and 4G/LTE frequency bands and band combinations that are either deployed or in commercial planning globally."
This article from Qualcomm states that the chip present in the OnePlus X is capable of supporting ALL LTE frequencies in use, or in the planning stages of development, as of Febuary 21, 2013. Where are Bands 12 & 17?
Am I correct in my findings? Will we be able to enable these bands with this method? http://www.xda-developers.com/add-frequency-bands-qualcomm/
if youre correct then i guess those features require higher license fees
thus theyve disabled them to keep costs down
I reckon they have the right chips, but haven't included all of the antennas due to size constraints. ie there is a 2.5GHz antenna for wifi, but not enough room for a 5GHz one.
Good news is, "It is not a hardware limitation" The link if I'm right is not working??? Trying to follow you. Update this link works:

So you're saying 5GHz WIFI and all LTE frequencies can be unlocked?
- edit -
O, now I understand, it was just about the link working, not the real thing.
All chipsets with integrated modems supports virtually all 2G, 3G and 4G frequencies that are user worldwide.. They are not activated because of bureaucratic questions, like regulators approval, licensing fees, etc.. etc... There are some examples on this forum of persons who succeed on activating frequencies that were previously deactivated on Snapdragon equipped phones..
WiFi is another story, because if the phone don't have a 5G antenna, then the fact that the chipset supports it, doesn't change nothing, because it will never work.
As I've mentioned in other related threads, once my OnePlus X arrives in the mail, I'll be sure to try my hand at unlocking band 17 since I have an active AT&T sim (I'll try band 12 too, but I can't verify that one).

Steady progress. I've gotten as far as were I can read and write NV values. This has required a lot of setup, mainly for Windows to communicate with the phone properly. The major problem I'm facing is that any NV value I write does not stick after a reboot. Thus far I've only needed root, but I may need a patch flashed and that will require TWRP. The OnePlus One required a RMT patch, so I'm going to try that later tonight or early tomorrow, making any modifications as required.

Makes me giddy thinking of all you pioneers hacking/developing for the OPX. This is the first time I've seen all these discoveries in real time rather than dug up the fossils of them months later.

Posting here as this is a very cool thread to follow.
So apparently it seems someone may have picked up band 12 on their OPX. Heres a link to the post in the OPX forums in the official OP forums:
https://forums.oneplus.net/goto/post?id=14158562#post-14158562
Want to test it out myself since I currently have another phone that actually picks up band 12. If I'm able to pick up band 12 in the city I'll have my OPX on hand to verify that it can pick up band 12.

The LTE discovery app is very unreliable on T-Mobile. There's many documented instances of false / incorrect information. It's the way T-Mobile sets up their network, it doesn't report the info, for apps to recognize the band.
The only true way to determine which band you're using would be to use the phones built-in service mode. Which the oneplus doesn't have ( I checked).
https://m.reddit.com/r/tmobile/comments/2w77an/tmobile_please_share_data_so_that_lte_discovery/
Also, here's the FCC approval document, oneplus or any company cannot add / change the radios without getting FCC approval.

I have not been able to. NVRAM values get loaded on boot. After unlocking my X's bootloader, I booted into TWRP and flashed the OPO's RMT storage patch. Let's just say it did not work out very well. Like cellular antenna not working at all, not so well. Thankfully I'm in the good habit of making backups before modifying anything and all is back to normal.
Any updates?
I don't understand One Plus. The One plus one, was/is such a great device. It put them on the map. The one x, is a beautifully designed phone. Why disabled/cripple the phone? To keep the price at $250? I would gladly pay $100 dollars more, for the one plus one, in the one plus x size, and design. I had to send mine back, because of lack of lte in my area on AT&T. Which by the way, I still haven't received a refund. And they received the phone back on 12/5. Their support is total crap!

Well Qualcomm's anti-tamper code is getting the better of me. I've tried using the Blu_spark kernal, but this did not rid of the code. My next step it to try and see if I can't to the mod on CM and have it live once OxygenOS is back on. This assuming CM can take the mod in the first place. I don't really want to have to flash a ROM for this mod. I was hoping to keep things as simple as possible so more people would take advantage this mod. Again, this assumes everything works as I hope it does. I'm so close, yet so far.

and a video teardown for good measure.
so, what about this T-mobile 3G nonsense?
in November 2011 Skyworks announced that they would be providing their Multimode, Multiband (MMMB) power amplifier modules. in their press release they discussed two different chips the Skyworks SKY77606 and the SKY77604. for our purposes here the only difference we need to worry about is the SKY77604 support's T-mo's 3G and the 77606 does not. up until now nobody knew which of the two chips the Note was using in it. you can find the press release Here
if you can't see which one i'm talking about
it's hard to see. but the number on the top row says SKY77604. all we need now is the proper Modem/software modifications to enable 3G.
big thanks to XDA.cn for doing the teardown. you can find the original pictures here. Clicky
you can find detailed schematics and information for the SKY77604 here Clicky
There's a couple important points from that Skyworks page.
"This functionality covers multiple bands for 3GPP including bands I, II, IV, IX, X, V, VIII."
"The module is fully programmable through a Serial Peripheral Interface (SPI). "
For an exaplanation of bands, for those who need to become familar. Band I = 2100 MHz, Band IV = 1700 MHz.
http://en.wikipedia.org/wiki/UMTS_frequency_bands
The part about "fully programmable" through SPI is encouraging if Samsung doesn't already take care of T-Mobile support.

even if/when T-mobile decides to bring the Galaxy Note to the US it will probably end up with a Snapdragon chipset in it to further push the '42mbps' phone thing.
I don't understand that part about why the CPU needs to be nerfed in order to achieve a higher bandwidth.
In any case, the point here is that T Mobile doesn't need to retail the GNote. You provided evidence that currently shipping model is theoretically enabled for use on T-Mobile. Or is that the point?
Yes that was the point the hardware is capable of running TMO 1700/2100, so that said, The real problem is figuring which radio modem that can be adapted (ported) to the Note so it will recognize those bands and use them correctly.
Of Course... that is........ nothing else is needed. But this is all good news

you cannot just copy any radio.img and enable t-mobile bands. the radio and ril will need to be reverse engineered for it to work.
i suspect the Meizu Mx also uses the SKY77604, trying to hunt down the Modem from that now to see if we can learn anything. (it has Pentaband 3G enabled)

Of course, I was not saying that, but for sake of discussion here, in simple terms having something that is compatible and similar will take a lot of the reverse engineering experimentation and guess work off the table....... ergo not starting from zero.
It would be WAY easier if Samsung would just release that part of the code necessary for us to work off of.......... but I will file that wish with my chances of winning the lottery

the korean Galaxy Note has a snapdragon chipset right? if so nothing going on in here will apply to that. since i can't imagine it uses the same power amplifier.
best you can do is try to flash a T989 (T-mo US SGS II) modem and see if that makes a difference. i can't imagine it will work though.
can you try dialing *#2263# from your main dialer and take a screen shot of what shows up under WCDMA bands?
Man if we get T-Mo and Pentaband support on this phone I may just have to sell my GSM nexus.

that code does not work on my note.

and before that, i wish someone helps me with rooting this one.
if anything, it seems similar to Skyrocket, but to flash or anything, i need root access first, right?

It would suck if despite that, 3G still eventually never works on T-Mobile due to a lack of developers getting this phone. I won't hold my breath though.

The form factor and all the internals look identical to our variant. This is good news.
its beautiful and in spanish! its coming to me.
man can't wait. I really hope this one will support Tmo band, love the specs and the battery life.
Funny thing is, 3 hour SOT in my nexus 5 considered good battery life, while in this beast 6 hours SOT is some kind of "weak"? Wth? This is QHD. I absolutely love this phone despite a lot of hater out there are screaming everyday
I don't see this released to a few countries alone, I'm thinking more likely it will international with broad release but excluding the US. In other words Clove and the rest are going to have it for sale and getting it will be strictly a matter of dropping the plastic. But then again maybe that's just wishful thinking.
The US Droid Turbo works on International networks via GSM, right? So if this one has identical hardware, less branding, it could potentially work on VZW, right?

Not exactly. It would need a CDMA radio. Then it would need to support Verizon LTE bands. And then even if they pulled a Nexus 6, because of the CDMA radio, Verizon would have to allow it on the network, which is doubtful because they want to sell you a Droid Turbo.

No one really knows how Verizon is handling the activation of the Nexus 6. Droid-Life was able to pop a Verizon sim in their review unit and it worked. Maybe Google is giving them all the Id numbers and they are just allowing any Nexus 6 to activate in their network? I guess we will see when someone buys one directly from T-Mobile and see if it makes calls.

I'm guessing something similar happened with the Moto X 2013. I bought it from Moto, and it was branded as Verizon. I'd assume Moto told VZW here are all the serials for the VZW XT1060 models. With the Nexus, they may have just given them all of the numbers for all the devices, because I'm guessing you don't specify which carrier you have when you purchase, unless you're doing an upgrade.

Something tells me the United States is going to be excluded from this. Im sure it can be imported, but thats just going to jack the price up beyond being worth it.

Since the device HAS passed through FCC as IHDT56PK2 (the droid turbo is IHDT56PK1... the PK2 adds in UMTS/AWS = tmobile 3G), one can assume that they do intend to sell it within the US.
The FCC is a US regulatory body, and is only required for importing into the US.

Many devices pass through the FCC and don't ever appear from US consumption. While somewhat promising, its not nearly a sure thing.
Verizon may have an exclusivity right on the model preventing it from being sold on other carriers. At least for the time being. But there's been no press about it being released in the united states, so one can on speculate at this point.
Keep in mind that only means it can be legally imported, it does not show intent to sell. Similar processes are followed throughout much of the world and two variants of a GSM phone can cover most of them. There is little reason not to get FCC certification since it is not an expensive or difficult process within the confines of the larger effort involved in global release and one of the handsets will be suitable for use in the states anyway. I'm not saying its not going to happen, I'm saying the filing does not make it a certainty and more than one phone has seen certification without being sold in the US.
Also to the thread in general the spread of possible IMEIs are public record, Verizon need only block out the range specified for a device in order to block it, they do not need specific numbers off individual devices which are not public record.
I am opening this thread with the intention of enabling a discussion among the North American users (current/prospective).
It appears that Note 3 Pro (Snapdragon variant) is the logical choice for north american user, as it includes few of the 4G bands.
So, how is the network experience with the major cell phone carriers? Which firmware/rom includes those bands? AOSP/Global/China? Does VOLTE work?
I have been using the RN3P for the last couple weeks. I am in the Florida area in T-Mobile network, and really happy to see that I get 4G LTE most of the time. It's the band 4 according to the LTE Discovery app.
I have tried a bunch of different roms, including global stable, aosp and developer beta. I have observed that the network is much better with the developer MM roms. I am currently using the Epic ROM based on the developer rom, and I think I shall use it as my daily driver.

That's good to know. There are so many variants of this device, it's really confusing. I ordered mine from Gearbest last week, who knows when it will show up. The problem with these Chinese retailers is that sometime they themselves don't know what they have. I guess I have to see what I get. I just hope that mine also supports band 4, which T-mobile in USA also uses.
Are you still using China firmware? Does the china model come with Google Playstore?
http://willmyphonework.net/
most networks will work on the note 3 Snapdragon version (kenzo).
the Kate or aka Note 3 Special Edition model supports a additional 'band 20' which afaik is not used in the USA (someone confirm?)
the Mediatek note 3 Hennessy most likely doesn't have good usa network support
so make sure you get the kenzo or kate model, though I would stick with kenzo since the kate doesn't have as good of support or accessories

Mine came with Global 8.0.1.0 installed, prerooted, and unofficial bootloader unlock. I flashed official 8.0.1.0 global from tgz file, which then relocked the bootloader. I have done the official unlock with the same 8.0.1.0 official stable with no problems.
It came with Google Playstore, and some gapps (not all).
Anyone tried AOSP roms in north america? Does it also get the lte coverage?
I have heard privacy concerns from many people MIUI roms. May be rumors, may be not. But I don't wanna take the risk.

I have on hand experience with Umi Super. Which carrier you are on? With T-mobile Umi Super had really poor data connection. Barely got 3g, I couldn't even stream a YouTube video. I don't think it has any north american band. It's a decent phone for the price, but do your research first.
In Florida with T-Mobile network, using band 4.
I recommend changing the default apn settings to fast.t-mobile.com one, which better result for me.

This is a warning to all buyers of the Le Max 2 X821 sold by banggood in october / november 2018 with 4/64 GB!
They sold some sort of patchwork phone with bodies of X821 / X820 with suspectful having internals of X829.
Reason:
- Le Eco aka LeTV never build an X820/X821 (for the chinese or indian market) with 4/64 GB - the only model having this combination was the X829 for US
- LTE band 20 is not possible to connect (tested with several SIM cards)
- LTE band 20 cannot be activated (tested several firmwares)
Please test your device and report please!
Suggested app for testing: "Network Signal Guru" from playstore.
1. Root device
2. Start app
3. Grant root privileges to app
4. Tap three-dot-menu (upper right)
5. Select "Lock bands"
6. Select "LTE"
7. App shows usable bands
--> Please post results
Thanks!
I think I bought one of them.. I thought something was weird with the device model and firmware.. Well.. at least it works in my network.. Might get rid of it though as it has the camera problem..
I bought one of those too.
how to do the testing for the actual usable bands to be sure?

Please root device and install the App "Network Signal Guru" from playstore.
Start this app, grant root priviliges. Then tap upper right three-dot-menu.
Then select "Lock bands", then "LTE". After this the app will show the usable bands. Please post result here (screenshot). Thanks.
I got the following bands for my "X821": 1,2,3,4,5,7,8,12 and 17 (20 is missing).
For comparison: On my bq M5 I got all bands usable in germany: 1,3,7 and 20 (800 MHz)

Are you referring to this: https://www.banggood.com/LeTV-LeEco...8.html?rmmds=search&ID=46149&cur_warehouse=CN ?
But if you scroll down to specs you'll see this:
4G: FDD-LTE: B1(2100)/B3(1800)/B7(2600)
TDD-LTE: B38(2600)/B39(1900)/B40(2300)/B41(2500)
I do not see B20 listed there.
Plus, Max 2 for $130 with 4/64 GB?
That should be a raised red flag, considering the fact that a year ago *real* X821 3/32 GB was selling for $180-190.
Can you return it? I would.

Yes, I am referring to this. Until yesterday evening B20 was listed there. As I am new here to xda I cannot post screenshots... sorry
Thank you for your warning. :fingers-crossed: I was about to buy this at banggood (same link) and immediatly refrained after seeing your post.
after checking:
1. there is no LTE band 20 in this phone (and yes, when I ordered the phone it had band 20 in the product specs, now removed)
2. only one sim slot is working!!!! NO DUAL SIM!!
3. the box is fake, including the sticker with a production date of 07/2018
4. the charger is only 2A charger compared to the original 3A charger of the X820/X821 I have
the rest of the phone specs are comparable to my other X821, the roms work. it just seems the screen is slightly different in quality. The phone is definitely fake, possibly from the same factory than the original.
I have noticed that charger is not original, but other than that it looks legit.
Both sim slots work and i have 4g , probably my provider has other 4g frequencies too, i use 3g for battery anyways.

The focus problem. Clicking noise while is trying to focus and many times won't focus properly. Hit and miss. That's in stock ROM. Any other custom ROM is worse

I seem to have luck. Camera is working perfect on my device. But I will check dual-SIM, because other user wrote, on his Le Max 2 it does not work.
I would not call it fake if it is really x829 instead of x821, it is still better than refurbished or real fake. As i remember x829 was more expensive than x820/821, cdla earphones could not be the only reason.
Charger is leeco but i do not know for which model it was for with 1A, charger for my old x600 was 2A.

No earphones included here! I've two of these fake devices with band 20 missing. Band 20 is still an important band in Germany. There is a reason why different models exist. Calling something fake is absolutely legit in this case if someone (banggood) flashes the firmware to pretend it's another device and sells without pointing to this circumstance. I will even go that far to call it a fraud.
Well, I have bought my phone from banggood during that period (rose gold, as it was the only colour available), and two SIM cards work fine in this model, have installed LineageOS 15.1 and it works beautifully and it supports fix for camera focus (pictures are really nice). I have not been able to check B20 yet, though - but I have trusted specifications and I may confirm, that it was listed there, as otherwise I wouldn't have bought this phone. So, it is another example how tough it is to trust the Chinese merchants...
Network Signal Guru lists following available LTE bands on my phone: B1, B2, B3, B4, B5, B7, B8, B12 and B17. Indeed, B20 is missing and what about B38?
Frankly, am very confused - why does Network Signal Guru not list B26, B38, B39, B40 and B41 (sure, they are not used in EU at the moment but shouldn't it be reported by NSG)?
There is a site, which I have relied on - https://www.kimovil.com/en/where-to-buy-leeco-le-max-2 - and it is supposed to show, which phone supports this or that. Now, I am really confused... Sure, that phone is cheap and runs nicely - but nobody likes being lied to.
About Dual Sim: the preloaded rom allows data only in the first slot
Flashing any other rom from XDA solves that issue.
After checking band 20 it turns out the phone does not have it.
We have been fooled by BangGood or is it rather BangBad?
Dear Yerry,
I have LTE access almost everywhere in Poland, but only LTE bands B3, B7 and B8. I am not able to verify, whether there are areas where only B20 is available - and whether my phone would support it. But you cannot, alas, presume that if you have good LTE reception - it means, that B20 is there. There is a nice utility, 'LTE Discovery' which does not require root to report, which LTE band the phone uses at the moment. You may then have a look at its log, and verify which LTE bands were available - you can check there, if your phone has ever switched to B20. Mine has not, however. But, as said above, I do not know much about B20 availability in my country - so can't really tell. Gruesse.
Bought One to replace my old Galaxy Note 4. I check that I stop having 4G coverage with my current operator (Vodafone). This only emits LTE in the B20 band in my locality. So it has no B20 band. We have been deceived by Bangood.
Does someone have screenshots of a X829?
Would be intresting wheter it matches the fake version.
Has anyone else had this issue???
Last night Verizon pushed the System Update 3 enabling 5G. By wonderful design, they didn't include MY phone. Does anyone know where this file could be hosted or something...? I can't find ****...

5G not an option now, lost access to LTE
This is bs, but it also means they completely pulled even LTE access...

Might want to remove that language
Seems Verizon is trying to monopolize where you buy phones, chances are most people don't know about this limitation before they buy it.
Where did you buy your phone from?

You can plug into a pc through usb, in pulldown menu change usb options from charge only to system update, this will open a folder containing verizons upgrade assistant. Here you can find the ota

Amazon a couple months ago. Worked just until 11/13. Easy few months of service with minimal issues
so i was researching if i want to get this phone and i found something that might help you. take a look at this thread: https://www.reddit.com/r/verizon/comments/je9hai/nationwide_5g_on_oneplus_8_pro/ and the instructions here: https://mt-tech.fi/en/modify-oneplus-7-pro-5g-8-and-8-pro-nr-lte-a-band-combos/
I just got a 8 Pro and last night got a system update that seems to have enabled 5g. under connections my automatic network selector now shows an option with 5G added and im getting LTE+ that shows when I'm using data. now my speed test shows I'm getting almost triple my download speeds now at 148Mbs or so down . I honestly wasn't expecting any type of 5g access with how Verizon can be with non-branded devices.
Maybe you need to get the update to have it work like i did but just thought i would share since it just happened
This likely won't help you if you bought Verizon's 8 pro (rather than from OP or Amazon, unlocked). Sorry, but I'll just include the following:
I had been with Verizon for years, and then switched from Samsung to OP 8P. Love the OP. But Verizon poorly supports this device if it's BYOD. I couldn't get VOWifi or VOLTE, among other things.
After searching on XDA, I found the OP 7 Pro logkit.apk and used that for a bit, and it *did* give me VOLTE and VOWifi (you have to use some USSD codes to get to some behind-the-scenes settings, if I recall one code was *#*#INFO#*#* (crap, it may have been #*#*INFO*#*#), that opens up a really cool set of setting windows related to your cell signal, wifi settings, etc.
Ultimate super-awesome fix? I ditched Verizon and wen't with T-Mobile. (after 20 years with ATT or VZW).
Wow!! Instant wide-coverage 5G that actually works, instant support for VOWifi and VOLTE, and visual voicemail that works too. I love it.
So, I'm sorry OP (Original Poster)(not OnePlus), I realize this may not help you directly, but I really do feel your frustration, and just wanted to share my experience. Maybe someone may be helped a bit. And, no, I don't work for any telecom co. My job requires good phone signal etc and it has to be reliable, thus my taking a chance on T-Mobile.
Best wishes.
Oh hey original poster, the link you put is the one I looked at before switching carriers, because it said T-Mobile was the best for OP8P, and I agree completely. Good tech support too.
From the weblink:
=============================
OnePlus 8 and 8 Pro on T-Mobile 5G
As you may have expected, T-Mobile is the best-supported carrier for the OnePlus 8 and OnePlus 8 Pro. The unlocked models of both phones support T-Mobile's Sub-6 5G network, meaning you'll get the same network access as many of the phones it sells directly. T-Mobile's Sub-6 5G is the portion of the network that operates on lower frequencies, and has the widest coverage — you'll find its Sub-6 5G layering most of the same footprint as its LTE network.
The phones also support Sprint's mid-band Sub-6 network, which was the core reason T-Mobile purchased Sprint in the first place. So as T-Mobile starts to integrate Sprint's spectrum into its new larger network, the OnePlus 8 and 8 Pro are ready for it.
5G on T-Mobile: Everything you need to know
Curiously, though, neither phone supports T-Mobile's mmWave 5G network, which is admittedly small right now but is a main pillar of its overall 5G rollout nationwide — particularly in dense cities. This is even the case for the OnePlus 8 that T-Mobile will be selling directly, which is a head-scratcher.
For most people, Sub-6 5G is more important, especially in the next year, because T-Mobile's mmWave network is very small and only available in parts of a handful of cities. But it will become more and more important, so if you plan on keeping your OnePlus 8 for a couple of years, keep in mind that you won't have access to T-Mobile's whole 5G network as it grows.
====================
I just bought the OP 8 Pro from one plus and the only thing not working VOwifi but VOLTE is working fine and so is visual VM and now so is 5G for me yay . I do know when you BYOD you need to chat with support and provision your line for CDMA-Less if that's not added to your line things will not work there is a way to get VoWifi working but i never used it on my other phones so not really a big issue for me. i can see it being an issue for people with bad signal at home. i have had good luck using phones on VZW as long as they were certified as allowed on their network
Kind of related, I have a OnePlus 8 IN2013 on Verizon (if you are wondering why the EU model its because it was the only model I could find in Onyx Black) LTE and everything works fine on it but I wonder if I can get low band 5g enabled using the method posted further up. I already know I cant get mmwave 5g and honestly dont care but I cant for the life of me find what bands Verizon is using for their low band 5g
