6.0.1 new radio T-Mobile - Nexus 6P Q&A, Help & Troubleshooting

I had previously flashed the original radio for the 6p to have band 12 on T-Mobile. It worked great. My phone would switch from band 4 to band 2 and band 12 when necessary. Now that I'm on 6.0.1 and the new radio also uses band 12 my phone stays on band 12 only 90 % of the time. My question is for T-Mobile subscribers. Have you noticed this or is it just me? Being on band 12 primarily slows my lte speeds significantly. Another question I have is can I flash back to the older radio that permits band 12 usage while on 6.0.1? That radio was much better for myself. Both radios do show that they are using carrier aggregation when 12 and 4 are available. But I rarely see singularly band 4 or band 2 alone. I use the Lte discovery app to check what band I'm on. Almost Always band 12 and the Lte speeds prove it being only 5×5 deployment. Thanks to anyone who responds with true knowledge of checking this on their phone

You can flash back to a previous build to get your old radio back, just grab a copy of the factory build and use the radio image from that.

Or you can stay in whatever rom / stock image your on now and flash any radio at any time. Radio is independent of any ROM that your on

It's just you. I find that I only connect to band 12 when band 4 gets around -120dBm or worse, then switches back to band 4 when it gets stronger again.

Verizon xt1060 4.4.4 update works with T-Mobile SIM

I updated my Verizon XT1060 4.4.2 to the 4.4.4 with the posted method in the other thread. [FXZ] Moto X 4.4.4 212.55.26 (XT1060)
http://forum.xda-developers.com/moto-x/general/fxz-moto-x-4-4-4-212-55-26-t2827307
Now it works flawlessly with my T-Mobile sim using the unlocked GSM function.
Previously with 4.4.2 it would say "unknown sim", have LTE, MMS, SMS and voice call switching issues. Even forcing HSPA was inconsistant. Now all's well with my experience.
good to know, just picked up a tmo sim yesterday, but have it in my att note 2 right now
Sent from my XT1060 using Tapatalk
I'll have to try it with my T-Mobile SIM later
After further testing, I had to change preferred network type to LTE, GSM, UMTS. default settings were flaky after driving around town.
Rebooted a few times and airplane mode a few times. Still good for now. Settings stick unlike 4.4.2

I'll test it the next time I'm in an LTE area. The nearest one is 35 miles away. I could do everything on HSPA, but I had issues in LTE areas on 4.4.2.
I wonder if that means the Maxx will work perfect on T-Mobile when it gets triple 4

The maxx already has 4.4.4, had it before the X. According to several posts over there, LTE is still broken
The default APN on the XT1060 with 4.4.4 is now fast.t-mobile.com, so a manual entry is no longer needed. I still put one in though because I like to customize the APN type settings.
It now correctly falls to HSPA/GSM from LTE when calling out too, instead of locking you to CDMA voice. So, you can use the phone as a phone now, even when connected to LTE.
I'd consider this fixed now.
Did your set preferred network type to global or LTE,GSM,UMTS?
I originally had it at Global, but it started acting like 4.4.2 (problems switching between phone and data) after I started moving around town.
LTE, GSM, UMTS works good but takes a long time to find a signal if I come out of a no signal zone

I did set it to LTE/GSM/UMTS, and I added my own APN even though the default (hidden) APN is correct.
Yeah, even on Verizon, the phone is slow to switch networks. If I get dropped from LTE, it'll stay on 3G or 1X even though LTE is available; sometimes I get no data on Verizon for a while. Seems the same with LTE and HSPA switching.
I should add that Global mode doesn't lock to EDGE now, but it is sketchy, as you say.
I've been having calling issues using 4.4.4 when connected to tmobile LTE on my xt1060 dev edition. If I force GPRS, calls work fine, if I switch to LTE/GSM/CDMA auto (prl) I connect to LTE, but then can't make or receive calls. I haven't been able to figure out how to force H+ which seems like it would fix the problem, any ideas?
Also OP mentioned a "unlocked GSM" function, could you elaborate? I search these forums all the time but have never posted anything until now.
might work on AT & T? It may be possible?

Think it should work as it is supposed to be a GSM unlocked world phone.
For me 4.4.4 fixed some of the phone/data switching problems and issues with the gsm settings resetting after reboots.

Well Verizon is currently doing testing because I made a complaint against them with the FCC.
I told the Verizon guy that I can connect to T-Mobile LTE on 4.4.4 (though I had issues with 4.4.2), but that I didn't test voice capability very thoroughly while connected to LTE (fallback to GSM may still be sketchy). So, he said he'd get back to me after they've done some testing on this particular issue. I did say that 4.4.4 fixed a lot of the issues I was having though, mainly getting connected to LTE, and having overall GSM/HSPA network issues when the phone was trying to connect to LTE.
Looks like my issue is that I'm not in the so called "refarmed" spectrum area for HSPA+, so I can either get LTE, or EDGE, nothing in between. I've tinkered with the build.prop to no avail. Guess I'll keep tinkering.

That's interesting considering the same amplifier for band 4 AWS LTE is the one used for HSPA. Band 4 AWS LTE operates on 1700/2100 MHz, the same frequency as the non-refarmed T-Mobile areas.
I think I'm also in a non-refarmed area, but I do have access to HSPA. The download speeds are just highly limited (0.05Mbps), so there's likely some baseband setting preventing full speeds. The last time I had reliable HSPA+ in my area was on 4.2.2 where I could pull just over 1Mbps down. In better areas, I get 5-15Mbps on HSPA+. These are certainly 1900/2100MHz areas.

I'm confused. Are you using a Verizon device? The XT1060?
While perhaps the same amplifier is being used (I have no info to either confirm or disprove this statement), the XT1060 (according to all relevant FCC data) lacks the actual physical radio hardware to support UMTS on 1700mhz. Additionally, 0.05Mbps sounds MUCH more like EDGE data than HSPA/HSPA+ data.
I'm very curious now. Would you mind trying out this app:
https://play.google.com/store/apps/details?id=com.roaderster.mrf&hl=en
And seeing which UMTS (WCDMA) band/frequency it says you are using when your phone supposedly says you are using HSPA on 1700mhz?
We already know for a fact that the XT1060 does indeed support UMTS band 2 (1900mhz). I also *thought* we knew for a fact that the XT1060 does NOT support band 4 (1700mhz). LTE, yes, but UMTS, no.
I'm anxious to see what this app has to say...

The Skyworks 77619-12 is a penta-band amplifier that provides bands 1, 2, 4, 5, 8 support for HSPA/LTE and is used in the XT1053 and XT1060, among others. See here: http://www.skyworksinc.com/Product.aspx?ProductID=1024
I don't have root, so I used an older LTE phone without band 4 support, and put in a T-Mobile SIM. There was no signal at all, and T-Mobile says this will be so if a phone doesn't support 1700MHz even if it supports 2100MHz. So, I only deduced from that that I'm in a 1700/2100MHz area rather than a more typical 1900/2100MHz area. The limited down speeds are on HSPA+, but upload speeds are around 1Mbps.

Thanks for the link. As you already know (no doubt), an amplifier can do nothing if the underlying radio doesn't support the band/mode (UMTS on band 4, in this case). Likely, they use that same amp in all the Moto X variants (except, of course the Sprint variant, which uses band 25 on TDD-LTE).
The fact that the phone won't work unless both 1700 and 2100 are supported by the radio itself makes perfect sense since they are using FDD-LTE (Frequency division - requires 2 seperate bands - one for uplink and downlink).
Did you try the app I suggested? The description doesn't say it requires root...
And finally - you never confirmed: are you using the XT1060, or the XT1053?

The app only lists possible bands and converts them to frequencies. It won't tell you what bands the phone is using.
On 4.2.2, my XT1060 reported using bands 1 and 4 for HSPA, which is 1700/2100MHz. I figured it was misreporting.

Can't get 4g lte on nexus 4 with cricket service

I can't say for sure, but after a quick search, I noticed Cricket Wireless' network bands are the same as AT&T's. That means our Nexus 4 cannot connect to its 4G network even if you flash a hybrid radio.
I know tmobile ised band 4 for lte and att have the same band
ATT BANDS
4G HSPA and HSPA+*
850Mhz (Band 5)
1900Mhz (Band 2) bands but it all depends on area if they own a license.*
LTE*
Band 17(700Mhz),
Band 5(850Mhz),*
Band 2(1900Mhz),*
Band 4(1700/2100Mhz)*
LG/Google Nexus 4 that the device included hardware necessary for LTE on at least some of its bands, namely bands 1 (2100 MHz), 2 (1900 MHz), and 4 (AWS 1700/2100)
Ummm I'm on cricket and my LTE works fine

The Nexus 4 only has LTE with band 4, after you've flashed a hybrid radio and set it to LTE/GSM/CDMA auto (PRL) in your dialer settings (dial *#*#4636#*#* and go to Phone settings).
So should work perfect with New cricket service since used at&t towers and have band 4 too right?
But u dont know how get lte just got HSPA AND HSPAP may need another apn settings and specific radio?

I don't know how to get it to work properly with AT&T, and I don't know their APN settings. But there's this thing called "google" that might be able to steer you in the right direction.
Already try different apn settings but nothing work that's why i recur to you guys if can point me on the right direction

I know it's been a while, so hopefully you had the issue resolved. If not, have you tried contacting Cricket? I just switched with my Nexus 4, and in a chat they were able to provide all the info to set up Access Point Names. The same settings are listed at this website: https://apn.gishan.net/settings/60_22_cricket_apn_settings_for_lg_google_nexus_4.php
Upon rebooting the phone, a symbol "H" appeared next to the cellular symbol. Looks like it's better than 3G, although not quite 4G. However, it works for me just fine.

[Q] How to enable band 3 lte on nexus 4, running rooted 4.4.2?

Hi,
I did google around this subject, but unfortunately that just left me very confused!
I need to enable band 3 LTE on my Nexus 4. I am running Android 4.4.2, rooted and all that. I have to stay on this version because I can't manage to share the VPN connection when tethering on other versions. (Long story).
How do I enable band 3 LTE? Complicating factor: the middle of the touchscreen is broken so I can't use the keypad properly .
Many thanks.

There is no band 3 LTE on the Nexus 4. The only LTE band the Nexus 4 is physically capable of supporting is band 4, and this was left dormant (which is why a hack is required to enable it). My guess is it has band 4 LTE because the only US carrier to offer the Nexus 4 was T-Mobile, which had the rights to use band 4 (and only band 4), but at the time of release, they hadn't yet upgraded their network yet to support LTE. So rather than jump through the FCC hoops to get it certified, they just left it dormant. Regardless, you can only get LTE on band 4 on the Nexus 4.

Band 12 - T-Mobile

So I'm not the brightest with the different frequencies etc... What I do know is that Band 12 on T-Mobile has greater building penetration, and that it's currently not supported on the Nexus 6P, despite the phone having the band. My question is, what functionality do I lose? Aside from having more penetrating power, which gives me better signal, do I lose anything else? Honestly, I'm pretty sure Band 12 isn't even in Columbus, Ohio (where I am) yet... but I don't wanna buy this phone and then Band 12 go live here and then I lose LTE, if that's even what happens... or would it just resort to the current band 4?

Thats trouble for you. From what I understand there is a long certification process to get the certification from T-Mobile, especially if they do not sell the phone. The Nexus 6 DOES support the T-Mobile band 12:
Unlocked devices
The following unlocked phones not only support LTE band 12 but all other bands required to be compatible with T-Mobile network (LTE bands 2, 4 and 12, HSPA+ on AWS and 1900 MHz, and GSM on 1900 MHz) however band support is not the only requirement. T-Mobile issued a statement regarding band 12 unlocked phones: All Band 12 LTE devices on our network must support VoLTE, E911. Currently only three unlocked phones supports VoLTE and band 12:
Nexus 6 XT1103 (US model)
iPhone 6s A1688 and A1633
iPhone 6s Plus A1689 and A1634

well tmobile has already confirm the 5x/6p will work on their network... im just wondering what the lack of band 12 support (for the time being), means for me. i assume i would continue to run on the band 4 that i do now.
Not sure if you've found the answer to your question or not. If you dont have Band 12 where you're located then its really a moot point. I'm in Phoenix and there is a TV station still operating on the 700Mhz Band 12 spectrum so I dont have it. However, if T-Mobile lights up Band 12 and these phones havent received their certification then they will not use Band 12 at all. That means you're limited to Band 2 and Band 4 LTE. Assuming you dont have Band 12 in your area (it appears you do not based on the de-facto map that most cite reference to is here http://www.tmonews.com/700mhz-lte-map/), your coverage will remain the same as it is now.
That being said, Google has stated that they are working with T-Mobile to have the 6p certified by the time the devices ship. So if that holds true, and T-Mobile rolls out Band 12 coverage in your area you should theoretically get better indoor LTE coverage since low-band spectrum travels farther and has an easier time passing through obstacles like block walls. Until then, you should have a similar coverage experience to what you have now. You're not "losing" anything to answer your question.

Missing Lte Band 12?

Use my Pro 3 on the T mobile network ..
Notice when i am in large building i.e Walmart or Movie Theater..
I get zero bars..!!
Went to GSM arena [ http://m.gsmarena.com/leeco_le_pro3-8344.php ] and according to their specs, this phone is missing band 12 and 17 if your on AT&T.
Also according to lineage [ https://github.com/LineageOS/lineage_wiki/blob/master/_data/devices/zl1.yml ]
Now the site Le Eco Usa Says it does [ http://www.leeco.com/us/phone/leeco_le_pro3/ ]
So my question to the community is what gives??
Which version is true?
there are different version of Le Pro 3. The one with band 12 and 17 is the US version X727. check what version you have and if it's not X727 then you know what.
Went to settings..
Says Lex727..

as long as you get lte out in the clear places, it's just weak signal.:good:
This phone has B12. I've seen B4 & B12, B2 is the only one I haven't seen used. I checked with a signal app.
Band 12 Le Pro 3
Wanted to weigh in...I am using the LePro3 x727 in T-Mobile (north Miami, FL) and I have yet see the phone connect with Band 12. I have both Band 2 and Band 4. I am running lineageOS and using the app LTE discovery.

Hard to connect to B12 since B4 is the primary band here, but sometimes I get lucky.
I connect to B12 sometimes, but it is very rare. You can force Band 12 in Network Signal Guru and see if your phone connects to it (needs root). The network will always try to keep you on Band 2 or Band 4 on T-Mobile.
