I am having an issue with my Unlocked 10 I am not sure how to fix, or if there is a fix at the moment.
The phone works flawlessly and I love it, however, for some reason, regardless of the signal it wants to prioritize Band 4 over Band 12. I can use the LTE Discovery app to temporarily get it to 12 (in which the overall speeds work better the places I use the phone) but it shortly after goes back to Band 4. So needless to say it becomes an annoyance having to reset it from the App each time I want to be on 12.
Is there any possible thing I could to do fix this?
Its rather odd that you're getting better speeds on Band 12. Band 12 is a 5MHz sliver that is really just meant to patch holes in T-Mobile's coverage. I've never found it faster than Band 4 and I'm in a market that has 15MHz of Band 4 that isn't contiguous (so one 10MHz and one 5MHz) which means it needs carrier aggregation to even use them both.
That's one thing that I don't like about HTC phones compared to Samsung phones. Samsung phones give you complete control over the radio, including LTE band preference built in. As far as I'm aware, HTC has not implemented this ever while Samsung has had it at least since the Captivate (first Samsung device I owned). You're basically at the mercy of HTC's RIL.
Once an HTC RUU becomes available for T-Mobile, you could S-OFF and flash the T-Mobile RUU. Its quite possible that Band 12 is not optimized on the unlocked version.

Would it ever be possible for Verizon to become a cdma provider? I know nothing about how it works honestly but if its something they could chnagr and keep existing network they could if they'd have to start over obviously not. Just curious since where I live Verizon is the only choice but GSM just beats cdma on many levels. Sorry if this is in the wrong section or if it sounds as dumb as I fear it does.

No. They're (effectively) never going to drop CDMA. For the foreseeable future they will be using CDMA as a legacy fallback network. Eventually they'll push to VoLTE (Voice over LTE) and start to phase out sales of new CDMA devices, but that's far into the future. They still have to support millions of legacy CDMA devices.
Verizon is too large with too big of a user base to pivot to GSM. Honestly at this point even if they wanted to (they don't), it wouldn't be worth the time and effort considering they're pushing LTE as their next network technology. It'd just be a complete waste of time.
Damn. Reading about all the new nexus devices being only cdma has me hating where I live as T-Mobile or att would have no service 90% of the time.

Verizon is switching to GSM since they are moving to lte and the lte voice. They'll never go backwards to hspa though, and they likely will keep their cdma network for more than 5 years.
Notice new Verizon phones have sim cards?

Ya isn't lte the GSM type tech and umb or whatever its called was the cdma technology.
I was reading that vodafone (one of the biggest carriers in the world, GSM, has stock in verizon) and Verizon decided together that lte was the future instead of the cdma version.
Even with the switch to LTE, Verizon's LTE operates in the 700MHz band, which none of the GSM/LTE networks will be compatible with. The result will in all likelihood be two separate LTE networks.
With the investment that Verizon already has in their 700MHz equipment, it is highly unlikely for them to make a switch.

ATT is 700mhz as well.
Cdma keeps connection when traveling between towers much more reliably as well.

But different "parts" of 700mhz.
I don't know whether or not cell phone providers actually do this, (I'm not terribly familiar with how they work) but you can fit multiple carrier signals into the same frequency by adjusting the phase and polarity.
I know satellite providers do this. The even transponders use linear polarity (modulating based on variable strength of the signal,) and the odd ones use circular polarity (modulating based on the directional vector at a given point in time.) In addition to that (and I don't think satellite providers do this yet) you can add a second linear modulation with a phase shift of 90 degrees to add yet another carrier signal.

Yeah, AT&T uses A & B blocks in lower 700MHz. VZW is C-Block Upper 700MHz. While you could probably make an LTE radio that combines the Lower A, B and C (lower C =! upper C), getting all four bands to play nice is going to be very difficult.

So does GSM, as long as it's operating in UMTS mode (which it will, unless you're making a voice call on T-Mobile from an airboat 5 miles south of Alligator Alley (I-75) in the middle of the Florida Everglades & barely have a viable signal to begin with, in which case it will fall back to legacy TDMA-based 1G GSM).

They could... except then your phone would only work when uplinked & downlinked through a fixed, securely-mounted antenna. Doppler shift does terrible things to phase-based modulation. Just ask anybody who's ever tried to watch an 8VSB-modulated ATSC TV transmission during a hurricane (when the transmission antenna is wobbling) or from a moving vehicle. In theory, there are exotic antenna designs that can untangle polarized signals while moving by simultaneously receiving multiple phases & using a DSP to separate them out "after the fact", but they're *way* out of the current realm of viability for mass-market consumer electronics, and WAY more demanding than a 2" metal stub embedded inside your phone.
Truth be told, spectrum isn't the problem. Tower density is. The nice thing about CDMA is that you can literally fix almost any bandwidth problem just by throwing more tower sites at it & letting the network sort itself out like magic. CDMA has very few "hard" limits. Some, like 1.25MHz or 5MHz channel pairs, are carved in stone and can't be engineered around. Once you're in the club and own the spectrum, though, it's really just a question of "what kind of tower density are you willing to pay for. Crowded mall? Give it its own cell. More-crowded mall? Spread a dozen picocells around it, especially the food court.
Verizon is unlikely to ever support legacy GSM or UMTS directly, and can really only evolve into LTE going forward. Sprint could, in theory, buy T-Mobile, and instantly consolidate GSM/UMTS into any cell site where it has deployed Network Vision (~3% of the US, so far) as long as it had the use of T-Mobile's spectrum, with little more than a site visit, software upgrade, and some software reconfiguration. Verizon can't do that, because it ALREADY upgraded its network, and has too much in sunk costs to scrap everything and redo every cell site the way Sprint is (and MUST). Truth be told, Sprint won't do it either unless it merges with T-Mo, and the feds are unlikely to allow it (it's not 100% impossible, but VERY unlikely to happen unless there were simultaneously a merger between US Cellular, MetroPCS, Sprint's "rural" partner networks, and/or Cincinnati Bell (to preserve the status quo Quadropoly).
AT&T and Cingular switched to GSM because they had no meaningful upgrade path from TDMA. In fact, AT&T was actually planning to switch to CDMA until they bought Cingular, and altered their plans only because Cingular was already deploying GSM. In theory, Sprint+Tmo (with the spectrum of both) could semi-gracefully migrate towards GSM with backwards compatibility for CDMA2000 voice and 1xRTT (like Telus did in Canada), but NOBODY could really get away with "flipping a switch" and forcing a wholesale changeover anymore. Hell, Sprint doesn't even have enough Nextel customers left to pay the electric bill for their added tower costs, and the official iDEN sunset is STILL two years away.
Remember when AT&T chose to only carry the 16GB version of the S3, will US Carrier version availability of Note 2 be different?
http://www.engadget.com/2012/10/10/samsung-confirms-october-24th-event-is-for-the-us-galaxy-note-ii/
I'm leaning toward 64GB Grey & can go to any carrier.. Verizon has LTE in my metro NY area but would fall back to 3G where it doesn't have LTE coverage while AT&T has LTE about 15 minutes away but usually only falls back to HSPA+ that is way faster than 3G not to mention would be ~$10/mo less (yet I'm on FIOS 75/35 Wi-Fi or other fast Wi-Fi most of the time anyway) so not sure which carrier to go with, advice on carrier options? -Thnx
Still have the EVO 4G on Sprint which does not have LTE yet in the area & its 3G is slow so the unlimited data differentiator is not too compelling as I'm mostly on Wi-Fi & when I'm not would rather not deal with slow 3G, prefer minimum HSPA+ speeds..

AT&T Note 2 will most likely be unlocked while the Verizon version will most likely be locked. Seeing as you are on the XDA forums and you have fast wifi most of the time I would recommend the AT&T version. Being unlocked will allow you to run custom kernels and ROMs which allow you the ability to tweak your operating system and squeeze extra performance out of your device. AT&T recently added LTE in my city so that made it an easy choice for me along with all the benefits you mentioned of AT&T.
I would also like to get a 64GB model however I think its unlikely that will be released in the near future. Typically the higher GB models are released later.

Verizon & Sprint will likely carry at least 32GB versions, AT&T better not only offer the 16GB again..
Ideally I want Samsung Galaxy Note 2 128GB (64GB Marble White + 64GB MicroSDXC) on day1
This is a carbon copy from my post on howard forums but this is a more technically based crowd.
Well, I am hastily planning my transfer to ATT from Tmobile tonight and stumbled across the band list for ATT. I currently have a LG G2 which I really like a lot and was looking to go to a G4 when they are available.
I checked the current bands used by AT&T and the list is quite impressive. I have currently 4 towers within range of my house and a -90 db signal on my front porch. This is impressive since I only get Tmobile on my second floor or the end of my driveway. With Verizon, Tmobile, and Sprint the towers are about 3 miles away. AT&T has 2 towers that are 3 miles away and then two more within a mile. This is where the improved signal comes from. There is also a public safety tower less than a mile away. Both ATT and Verizon are dropping antennas on all the new public safety towers in the county. Sprint and Tmobile not so much because they are still in the LTE upgrade phase. So ATT is the logical choice even though data is capped. I refuse to go to CDMA and my work Verizon phone still doesn't work in some parts of my house. Not an option. I would still like it if ATT had wifi calling.
On to my question. I saw ATT will be adding band 30 support at the end of the summer. I am not sure if they own band 30 in my area but I am in the process of looking. According to phone scoop the LG G4 lacks band 30 support. The Samsung S6 has it. I really like my G2 and the G4 is the logical upgrade. I also know that the G4 has not officially been released so phone scoop and several other sites might not be accurate.
1) Does the LG G4 currently have support?
2) Is there future support with firmware upgrade when band 30 is actually available?
3) Is the chipset capable of it to be added with NV editing like with Band 12 on the newer phones without filters?
4) Should I not worry about this feature since band 30 is not owned by ATT in central Virginia.
5) Should I not worry about the G4 since the S6 is comparable?
6) Will the short range of 2.3 ghz negate the speed boost just like the 2.5 sprint currently deploys which seemed to only work next to the tower when it was WiMAX?
Thanks. Looking forward to having a phone that actually works like a phone and not a drive by wifi thief.
Thinking about this as my next possible upgrade, been with a Note 3 for about 3ish 4 years it feels like. After the bootloader got unlocked I had few reasons to upgrade. Now however the hardware is getting dated and this looks like a viable upgrade. Would this phone work on Verizon's LTE network at full speeds, I am assuming there will eventually be a CyanogenMod released for this and then all I would need to do is unlock it?
Don't count on it
It's sadly not that simple from looking into it for the Mi5... However if they make great progress with the Mi5 there could be hope for this device as well since the 820 and 821 have few differences (or none? just an OC?).
The Mi5 is able to make calls and text at the moment but the LTE is still a bit unstable. If this looks like it will get enough support I might choose it over the Pixel XL. And if it works on Verizon since I still have my unlimited data plan.
I'd like to see B2, B4 and B12 LTE bands unlockable. I'm guessing monitoring progress on the mi5 is the right move since they have similar hardware profile.
Hopefully the chip can support the bands, otherwise it's another great phone that wont see it's potential in the us/eu market.
I bought this phone for several reasons, the great Camera, rootability, but Mainly for 5G and faster data. It's Rooted with .037. Since I had my years old sim in the phone all I was able to manage was about 35 Mb/second on 4G. So I headed to the ATT store and got myself a new sim card for it. On the way home I did a speed test and got 75Mb/second, 5G. Great, I thought. So when I got home I wanted to do some speed tests, and it was on 4G. I have an anntlent booster in the house due to having a metal roof. It has the following bands. each can be adjusted Individually:
LTE Band 12 Uplink (698~716MHZ) Downlink (728~746MHZ)
Band 13 Uplink (776~787MHZ) Downlink (746~757MHZ)
CELL Band 5 Uplink (824~849MHZ) Downlink (869~894MHZ)
PCS Band 2 Uplink (1850~1910MHZ) Downlink (1930~1990MHZ)
AWS Band 4 Uplink (1710~1755MHZ) Downlink (2110~2155HZ)
I turned down all the adjustment screws and took the phone outside. It connected to the PCS band 2, 5G. Took it back into the house, it was showing 1-2 bars. So I turned up the gain on band 2. The signal strength jumped up, but the phone instantly jumped to 4G. I thought it was supposed to go to 5G on a strong signal, then fall back to 4g if necessary. I tried *#*#4636#*#* and setting the phone to "nr only", but you night as well piss up a rope, the phone ignores these settings and resets itself to "unknown"
I fiddled with it some more and got a solid 5G icon. But only 5 Mbps download. For a couple hours messing around, and re pointing my antenna to another tower, I finally got a 4G signal on AWS Band 14 with 15Mbps, less than I was getting with my old 4G Sim.
I would like to see this thread developed with better Radio versions, hopefully ones that can be actually locked to what they are set on, whether it be those who want to avoid 5G or those who want to enforce 5G. 5G IS definitely faster in my rural area. Software I used to help diagnose this, and cell tower locations: Network cell info (an older version from an old phone extracted with apk extractor because the new one on google play kept crashing) Open Signal, and I tried Network Signal Guru, but it did nothing on this phone. Please post any ideas you may have concerning Radio connectivity, Booster (resetting) better software and firmware, etc.
@GivIn2It I've changed the prefix of this thread from "Development" to "General" as it didn't qualify for the first. Please review the stuck guidances at the top of the forum and do not change the prefix back.

Does AT&T even have real 5G (NR) deployment in your area? If so, is it NSA? If so, it probably uses B2 as the LTE agg link. According to the site below, ATT is supposed to be on n5/850mhz. You need to find out how ATT handles it's NSA deployment, but I guess you need to have B2 + n5 at a minimum.

Not sure if the Network Signal Guru betas are fully public yet, but they work great with the Pixel 6. No band locking though.
Contribute device capability info if you can to the cacombos site. We won't learn anything about what the Pixel 6 is capable without field testing. There's no documentation or data sheet for the "new" 5123b modem in the phone.

Thanks for that info. Apparantly, there is some aggregation going on. When the phone switches to 5G, none of the software including the Phone Info page will detect what band it's using. Phone info does show NR Available: True and NR State: Not_Restricted.

OK, then. How am I supposed to obtain that device capability information to upload to Cacombos, I don't have software capable of obtaining all that information from the phone. I'm willing to share information if you're willing to share the software that can obtain the information.

Problem is this, not sure the instructions are compatible:
This works with Shannon modem devices except Samsung Exynos device (eg. Pixel 6 and 6 Pro). For Samsung, please use Exynos internal logging by exposing modem to Scat, ShannonDM or Airscreen. Require root.
Open terminal with adb shell or with Terminal app.
Start logging with in superuser (su)$ su
# modem_logging_control START
Turn on Airplane mode and wait for 5-10 seconds. Turn off Airplane mode.
End logging with command# modem_logging_control STOP

Instructions under "Samsung device" references OneUI shortcodes which won't work with the PX6/P
It works. The wording is incorrect. It works for non-Samsung Exynos devices.
This is how we gathered the combos until NSG started working.
But the reason why we need more data is because one report from one phone only reflects the country they're in and what their carrier supports.
It's like cellmapper, more data is better.
I think I have figured out the problem. The Pixel 6 Pro doesn't like it when I have all my gains all the way up, at least for 5G. When I set the bands CELL Band 5 Uplink (824~849MHZ) Downlink (869~894MHZ) and
PCS Band 2 Uplink (1850~1910MHZ) Downlink (1930~1990MHZ) to a little over halfway, the phone regularly connects to 5G, especially when downloading. The signal icon on the phone varies between 2 and 4 bars. Download speeds about 2- 15 Mb/s, which is about a third of my better 4G speeds. But I get to see a pretty 5G icon on my Phone. Superb! My next step is to buy a honkin Yagi to replace my pathetic one, and do some signal searching to see if I can pull in that 75Mb/second tower. If that doesn't work, It's just wait for ATT to improve their 5G here, as I have determined that the Pixel 6 Pro is (mostly) working correctly out of the box, it is looking for the best signal, and if that's 4G, that is what it will switch to. Being more of a hardware guy, I think I can accomplish more with external equipment than I can monkeying with the guts of the phone. Rooting was scary enough. But I'm still open to flashing a better radio, when someone comes up with one.
