OnePlus One on LTE Band 5

Fellow XDA'ers:
I've tried asking this in the "Unlocking additional LTE bands" thread, but haven't had any success. From that thread, it seems possible to unlock LTE band 5 on the One, although it does say that not all bands can be used due to "hardware limitations". From what I've read, that seems to be limited to Band 20 though.
My question is: has anyone successfully got the One working on LTE Band 5 (850mhz)? It's the only LTE band available in Vermont at this time. I followed the instructions and changed all the NVRAM values, but I can't get LTE to work. I know 850mhz here is shared between GSM and LTE. Is there something else I need to do besides editing the values? Do I have to select any bands in software? When I dial *#*#4636#*#* I have LTE/GSM (PRL) selected, "Automatic" under band selection, and then I have LTE set in Cyanogenmod.
Any input is greatly appreciated!

I assume you double-checked after reboot that the values remained in place? Did you do the rmt_storage patch? Without the patch, the values wont stick in the latest modems.

Yes, I've double checked to make sure the values survive a reboot. I also used the patch. After some research it looks like there may be an issue when band 6 and band 19 are enabled that causes Band 5 to not work on LTE. The problem is that I don't know what NV value I should use to only enable LTE bands 2/4/5/17. Is there a way to calculate this value?

Yes, you can use NV Item calculator from here:
https://play.google.com/store/apps/details?id=org.vndnguyen.nvcalc&hl=en
The NV Items are standard across all Qualcomm based devices.

Thank you! I calculated the value for bands 2/4/5/7/17 (matching what is available on the HTC One (M8). I'll give it a test this afternoon.

Still no LTE love here in Vermont. I used the NV Calculator to determine the NV 6828 value for bands 2/4/5/7/17. That value came out to be 65,626, which I input as 65626. I wrote the file, rebooted the phone, and verified that the settings kept.
My iPhone is connected to LTE on Band 5. My OnePlus just won't connect.
Are there any other settings that may need to be changed?

Did you update 6829 as well? I believe one is the supported bands, while the other tells the it which of those supported bands to use.

Yes, I did change both the 6828 and 6829 values. LTE is selected under mobile networks in Cyanogenmod, and LTE/GSM (PRL) is selected under *#*#4636#*#*. The band selection is set to automatic.

Hmm, I don't see anything wrong.
I guess one last thing to do is able band 5 only and see if it works.

I tried that as well. For some reason the phone can connect to 850mhz on GSM, but not 850mhz on LTE. I can say for sure that the OPO does not support LTE on Band 5 even if the band is theoretically unlocked.

Have there been many people who can confirm that this unlocking method works at all for the Chinese OPO? I've been trying to get Bands 4 and 7 to work and I can't get anything above H+. Does this only work on a certain ROM/version by chance?

The method used on the global version of the OPO isn't specific to that version. All qualcomm-based devices are subject to the same method. You can find more information here for the OnePlus (both global and Chinese variants), and here for other qualcomm models such as the Galaxy S5. Both forums show that many people have had success unlocking additional bands.
Now comes the bad news. Just because you theoretically enable a band on the phone doesn't mean that it will work - as is the case with Band 5 on the global version of the OPO that i'm using. The phone also needs to have the correct antennas to connect to those bands. In my case, I can connect to GSM using the 850mhz band, but for some reason the same band cannot be used for Band 5 LTE (850mhz). I don't understand why this is the case, but I have yet to be able to get it to work.
Your luck may be better. It looks like the Chinese version runs bands 1/3/7. The global version is 1/3/4/7/17/38/40. If they do indeed have the exact same hardware inside, then a simple software unlock SHOULD allow you to turn the Chinese version into the global version. If they have a different antenna, then your results may vary.
As far as I know, there is no specific version or ROM that you have to have. If you have one of the newer versions of the software, you need to be rooted and install the RMT patch. See the first link I posted above for information on how to do that.

Been to that thread, it's kinda dead now. Followed the instructions and don't get LTE bands 4 or 7 with Virgin/Bell, does that mean the Chinese OPO doesn't have the required hardware after all for those bands? Maybe Band 7 is not available in my area but then 4 must be since I had LTE on my other phones. Or maybe my phone is just faulty. Would love to know if there is anyone successfully using a Chinese OPO on the Bell LTE network.

LTE Bands for International Version

I've been trying to find the LTE bands for the International/European version of the S6/edge for a couple weeks now but have had no luck with any sites I trust. I was able to come across this site: http://pdadb.net/index.php?m=specs&...g925f_galaxy_s6_edge_lte-a_128gb_samsung_zero
Does anyone know how accurate this site is or know of where I might be able to find trustworthy specs?

Also interested in this. I might get an international version, but want to know if it will work here on the US on the AT&T network

Interested as well, if the international version supports ATT Lte that would be awesome

It means the phone(s) should work on both AT&T and T-Mobile. AT&T uses bands 2, 4, and 17. T-Mobile uses 2, 4, and 12. The International version supposedly supports 1, 2, 3, 4, 5, 7, 8, 18, 19, 20, 26.

Sorry for stating the obvious, but no support for band 17 and 12 on the international version then? What does this mean in teems of coverage and speed?

Where there are cell towers that are broadcasting using bands 12 or 17, you will not be able to get LTE coverage, but you will be able to get coverages for towers broadcasting on bands 2 and 4. Your real world coverage will depend on where you live and how each carrier has decided to configure their networks, but you will be able to have LTE for both.
[edit] Both 12 and 17 are 700mhz frequencies, which means that indoor coverage will not be as good if you don't have those frequencies. So that's a trade-off you might want to think about before going with the International version. Though for the most part, many people will have access to a wi-fi network while at work and at home, which I assume would be where most people would be for most of their day.

From what I've been reading, WiFi calling/texting features only work if you buy a T-Mobile specific device. Any other phones used on T-Mobile won't work with WiFi calling/texting features. That alone is the reason I would not buy an international phone and use it on T-Mobile.

Hi guys,
I have noticed that the verison I can purchase in France is the SM-G920FZ-02. Is it the same thing as the SM-G920F ?
I am unable to find the LTE bands for this version...
If it is not the case, I guess i could just get the SM-G920F from another country ? I've seen it on the UK version of the Samsung website.
I'm travelling a lot between Europe and the US so it's one of my main concerns but apparently Samsung doesn't give too much information on this yet!

FCC filing show the international model will support LTE band 2, 4, 12 among others: https://apps.fcc.gov/oetcf/eas/repo...ame=N&application_id=794688&fcc_id=A3LSMG920F

Based on the info so far in this thread , it would seem like a safe conclusion that the 920F international version would indeed work fine on the AT&T LTE network

So does it support 12 and 17?? I'd be interested in getting the international for ATT. Just not sure what will and won't work

Band 17 is a subband of 12 (12 is the larger scope that includes 17 in it). The S6 920F support band 12 so it should work on AT&T just fine.
Bands 4 and 2 which are also used by AT&T are also supported according to the FCC documents so i assume the international model 920F should work just fine.
I can't be sure the same about other 920X models out there.

Does anyone know the difference between the 920F and the 9200?

Samsung I9200 is the Galaxy Mega. Is that what you're referring to?

I realised that there are commonly 2 available international versions, SM-920F (European?) and SM-920I (Rest of the world?). Wondering if anyone has the LTE specifications for the SM-920I version?
Edit (4 April): Found the answer to my own question at the Singapore Samsung website (under Specifications). So LTE Bands 1,2,3,5,7,8,12,17,18,19,26,28. No Band 4 though. I'm guessing that would greatly degrade the LTE experience with AT&T and T-Mobile?
4G+ LTE Cat 6 up to 300Mbps, VoLTE, 4G+ LTE FDD [Band 1 (2100MHz)/ Band 2 (1900MHz)/ Band 3 (1800MHz)/ Band 5 (850MHz)/ Band 7 (2600MHz)/ Band 8 (900MHz)/ Band 12 (700MHz)/ Band 17 (700MHz)/ Band 18 (800MHz)/ Band 19 (800MHz)/ Band 26 (800MHz) Band 28 (700MHz)], 4G+ LTE TDD [Band 40 (2300MHz)]

Edit (8 April): Interestingly, the Australian Samsung website for the same model (SM-G920I) shows that Band 4 is supported. I'm totally confused now as to whether this particular model supports LTE Band 4.

LTE Bands on an N920T

Going by the specs I've seen on a number of tech sites, I've always thought that the LTE bands on most T-Mobile phones were limited to those that T-Mobile and AT&T use (4 and 12). However, when I ran "search for operators" I could see Verizon (and ATT + TMo) towers. Then I found this page at T-Mobile's own website that shows this:
InternationalQuad Band GSM; LTE: 1, 2, 3, 4, 5, 7, 8, 12, 20; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850)​​
The UMTS bands obviously are TMo's, but LTE covers way more than they have deployed. So it would seem the N920T really has these bands? Perhaps it's because the chipset is Exynos.

You can see and change the band's from the dialer using *#2263#
I don't recommend changing them but you can look at the list.
I did change the default bands to LTE/WCDMA/GSM on mine for use on AT&T

That's interesting. When I execute that USSD, it shows way more bands than I quoted from TMo's spec list:

And this continues into the 40s, I just can't remember how to screencap the entire page. I am curious if they are all actual bands you can use, or (I would assume at this point) every possible LTE band there is. But it's a feature code I haven't seen before, so +thanks.

Well, after further digging in the *#2263# screens, this definitely looks like an international kind of phone.
If the settings are to be believed, there's also support for TD-SCDMA, which is an alternative to W-CDMA (and incompatible with it). That's used in China, which is a long way off from T-Mobile territory.
But that's great -- such an enormous frequency list is exactly what a flagship should offer. And it's probably no coincidence that this is an Exynos chipset, because other phones using Qualcomm seem to have restrictions in place for the US market.

Is it possible to change Bands (LTE & 5G) on SM-N9860 For Rogers Wireless in Canada?

Is it possible to change Bands (LTE & 5G) on SM-N9860 For Rogers Wireless in Canada?
I had a thought:
Currently, the Samsung Galaxy Note 20 Ultra 5G Dual Sim (SM-N9860, Snapdragon) 12GB Ram 512GB has the following LTE & 5G Bands:
4G FDD-LTE:
B1(2100),B2(1900),B3(1800),B4(AWS),B5(850),B7(2600),B8(900),B12(700),B13(700), B18(800),B19(800),B20(800),B25(1900),B26(850),B28(700)
4G TDD-LTE:
B34(2010),B38(2600),B39(1900),B40(2300),B41(2500)
5G Sub-6 FDD:
N1(2100) / 5G Sub-6 TDD: N78(3500),N79(4500)
Now, I am with Rogers, which requires the following bands:
LTE Bands:
700 MHz Lower A/B/C: 12/17/13
850 MHz CLR: 5
1700/2100 MHz AWS: 4
2600 MHz IMT-E: 7
1900 MHz PCS: 2
While SM-N9860 supports all but one - Band 17 LTE bands - the phone should work almost flawlessly with Rogers in terms of LTE. However, when it comes to 5G, it is a complete different story.
5G Bands:
2600 MHz IMT-E: n38
600 MHz DD n71
The Canadian (similar to the US) variant of Note 20 Ultra 5G supports the following band:
LTE Bands:
B1, B2, B3, B4, B5, B7, B8, B12, B13, B17, B18, B19, B20, B25, B29, B30, B66, B71
5G Bands:
n41, n66, n71
Questions:
1. Since both are based on the Qualcomm SM8250 Snapdragon 865+, is there a way to change the LTE & 5G bands?
2. Is it hard-coded into the firmware of the 5G modem that is incorporated with the Snapdragon 865+, which makes it impossible?
3. Does that fact that SM-N9860 has a unlocked bootloader and it is rootable, would this help change the bands or matters of the bootloader / root does not have anything to do with the frequencies / bands?
4. If the matters pertaining to unlocked bootloader/rootable , should this question be asked in the thread that Dr. Ketan discusses, with regards to the rooting process?
5. Only reason that I ask for all this is: recalling from memory from earlier days of Note(s) 1 thru 4 - rooting, installing custom rom (thru odin), etc. - I remember coming across a "modem" specific file that gets flashed by odin. Is that still true these days with the newer Note models or it is different?
6. I understand that Qualcomm supplies the specific modem chipset, with regards to 5G - would any of their development tools supplied by Qualcomm can help with changing the bands?
Thanks, just wanted to know.
Thanks.

It seems no one has replied.
Is it really that hard to change the LTE & 5G bands on the SM-N9860 model, given that it uses the Qualcomm SM8250 Snapdragon 865+ chipset (which I am presuming it has the 5G embedded modem)?

Years ago we used to be able to play around with enabling bands using something called QPST ( i think, its been awhile) but i have no idea if it will work on new devices.
Id suggest tailoring your search to that and see what state its in.

Depends on carrier... But I want to say it's the n261 and 260 and anything above 28... I could be wrong... I'm not in a 5g area... But I checked the vZw bands... Idk for other carriers

I think Rogers, Telus and Bell are all using band 66 for their 5G.

Question Can the CN Xiaomi 13 be fully support by T-Mobile in the US?

Hi everyone!
I'm considering buying a Xiaomi 13 while I'm still in China and flashing the Xiaomi eu ROM. The CN version is much cheaper than the global one. I'm a T-Mobile customer and wondering if anyone has used a CN Xiaomi 13 in the US before? I've heard that sometimes the CN version Xiaomi phone may have issues to fully use 5g or 4g network in the US. Please share your experience here, and thank you for your time!

Cn 5g 1/4 bands 4g 2/6 bands
Global. 5g 2/4 Bands 4g 5/6 bands

It's about the Global version not CN.

yeah, i am trying to delet it but in "edit" section there is no delete otion...

I came across something interesting. This website actually compares the band coverage difference between the CN and the global version. It seems the CN ones normally get lower coverage, but I still have no idea how bad it could be since I have no idea what type of bands are covering my living area...

Thank you man!

I'm also in the US using Google Fi which uses T-Mobile. I'm also dual SIM with ATT.
I ended up getting the Global version because it had more supported bands even though it was more expensive... Ended up getting the 12/256 for $860 on eBay.

Aloha,
Wonder if you can help? I purchased a 13 pro and having a hard time connecting to T-Mobile service. I have been working with tech support and I'm unable to make and receive phone calls. When I try to make calls the service drops. Im able to use data (internet) but unable to use the basic phone functions. Could you please let me know the apn settings that your using or have any suggestions on how I can get this service to work? I'm in the US.

Here you go.

Mahalo for you quick response. So you default is the epc I would assume. Let me try. Did you do any other tweeking to the apns? My other question would be is the sim with the att getting the service and not the T-Mobile? Have you tried with just the T-Mobile sim?

Did you ever get this squared away ? I am looking to buy the 13 pro within the next day or 2

The CN versions should function, though you'll likely experience signal outages due to only having a few of the frequencies. If you're looking to use the 13 in the USA, then the global version is what you'll be better off with.

I have a CN version phone and MintMobile (reseller of T-Mobile) SIM. It works fine. Plug & play. No special setting needed.
