[Nexus 6P Q&A, Help & Troubleshooting] wooddale:
I wouldn't be to concerned about speeds that's a tower thing unless its slow slow. Im thinking about trying that old radio. I asked this before in Heisenberg's list of radios there is a 2.47 radio anyone try this or know what it is?
[Nexus 6P Q&A, Help & Troubleshooting] zehcwb:
Yes, having problems here in Brazil since the update. I have to force LTE, if I just restart the phone it sticks to HSPA.

Revert to 2.15 (November - mdb08m) modem got me my LTE back

(AT&T, 2.62 systemless SuperSU root, all relevant 6.0.1 (MMB29M) images flashed in fastboot, then reverted to 2.15 modem to resolve LTE issue)
[Nexus 6P Q&A, Help & Troubleshooting] byproxy:
So LTE Discovery says I'm on band 4 LTE, but it says I'm roaming on extended network, as does my phone (r above signal bars and extended network on lock screen). Again, on VZW.

I don't get it... I'm in town. Shouldn't be roaming and I'm on LTE, so why am I roaming? I should be on vzws network for sure here in town.

Either I'm blind but do we have a thread of twrp flashable radios?
[Nexus 6P Q&A, Help & Troubleshooting] Badger50:
Not yet. However, fasterboot flashing works just fine :)
[Nexus 6P Q&A, Help & Troubleshooting] choder:
I flashed the 2.15 radio and now my LTE seems to be working fine. I am on Verizon and had the same problems. It would go straight to 3g when leaving a wifi network. Toggling airpIane mode made LTE work. But this old radio seems to be working right now.
[Nexus 6P Q&A, Help & Troubleshooting] byproxy:
Flashing 2.15 made no difference for me. Guess I'll have to try a full format and clean flash. Super sucks.
[Nexus 6P Q&A, Help & Troubleshooting] mistermojorizin:
I have, it seemed like it helped at first, then back to old behavior. Are you on Verizon?

I've tried all 4 radios. 1.29, 2.15, 2.47, and 2.50. Each one, I felt like it worked on the first few bootups, then back to the 3g at bootup. It's as if somthing doesn't turn on correctly (lte radio) during boot process, because a softboot later (with the lte radio already on) solves the problem as well. Of course the airplane mode does too, but that turns everything on and off. Soft-reboot just restarts system UI, and apparently, it's in a way that the LTE radio isn't blocked from connecting.

Anyway, I've had the most success with 1.29 and 2.47, but then the problem comes back. On 2.47 I somehow stopped getting volte for a while (though I was connected to xlte). So I just flashed 2.5 back and will see how it behaves.

edit: from the line of thinking that problem is something during boot, I tried disabling the SuperSU setting "make SU available during boot." That also seemed to improve things for awhile. I know the new systemless root messes with the boot image, dunno if they're somehow related.
[Nexus 6P Q&A, Help & Troubleshooting] wooddale:
I also flashed all 4 2.15 still the best however I'm still on 6.0 bootlader and 12-1 ROM. It almost worked like its supposed to but you still have to airplane sometime but it grabs and holds on when it does.
[Nexus 6P Q&A, Help & Troubleshooting] nrfitchett4:
I'm on pure nexus 12/9 update which is the new 6.0.1. On AT&T I'm stuck on HSPA/HSPA+. Guess I'll try to flash the older radio.

---------- Post added at 07:28 AM ---------- Previous post was at 07:27 AM ----------

Got that update yesterday after clean flashing pure nexus. I'm still stuck on HSPA+.
[Nexus 6P Q&A, Help & Troubleshooting] uknowme4me:
I received the OTA yesterday and I was stuck on H until I switched AT&T APNs. I switched from nextgen to AT&T phone and back to nextgen and my LTE came back on right away. I also haven't noticed any speed issues so hopefully that fixed the issue.
[Nexus 6P Q&A, Help & Troubleshooting] choder:
I have been on 2.15 for a day now and have had no issues.
[Nexus 6P Q&A, Help & Troubleshooting] dwertz:
I have tried every way. I flashed the old radio on 6.0.1 and it seemed OK until I tried to use data, then back to 3g. I can not get it working with any config with 6.0.1 but everything works good with 6.0 even the new radio. Take in account, when I say 6.0.1 that I mean bootloader and vendor also.
[Nexus 6P Q&A, Help & Troubleshooting] mr mystery:
I'll just wait for 6.0.2
[Nexus 6P Q&A, Help & Troubleshooting] chrisexv6:
Was going to ask if this is how it will work.

I have a feeling they wont wait a month to fix an issue like this. Its not like its a UI thing or something, we're talking basic functionality of the phone being affected by a bug.
[Nexus 6P Q&A, Help & Troubleshooting] byproxy:
Not sure what I did... But things are working now on the 2.5 radio for me on vsw.

Fwiw, i flashed the 6.0.1 update and had the lte issues. I flashed the 2.15 radio and continued to have the same issues. Flashed back to the 2.5 radio and reset the apn and now im gtg.
[Nexus 6P Q&A, Help & Troubleshooting] choder:
Are you on Verizon? I am.
[Nexus 6P Q&A, Help & Troubleshooting] dwertz:
Yeah, I am on Verizon.
[Nexus 6P Q&A, Help & Troubleshooting] lucky_strike33:
How did you reset the APN?
[Nexus 6P Q&A, Help & Troubleshooting] jeebuspwnz:
This "problem" isn't really anything more than an annoyance. I've found that when I reboot my phone I am on HSPA+ for 2 minutes on average before it jumps over to LTE. After that, it stays on LTE just fine. If I go through an HSPA-only area it drops down successfully, then reconnects to LTE when possible. So other than that initial 2 minute wait, there's no problem. I'm on AT&T fwiw.
[Nexus 6P Q&A, Help & Troubleshooting] mistermojorizin:
I don't think ATT is affected. I'm on verizon, and it boots into 3g and wont switch to lte until the radio is turned on and off (that's what airplane mode does, but there's a couple other ways). Can't force it into LTE even if I select LTE Only from the secret phone menu. Also, just curious, is HSPA the same thing as 3g? I noticed that the bug on google forum talked about HSPA, but that's not a universal term. I think talking in generations (3g) is more accurate because there was a 3rd generation of cellular tech no matter what your carrier chose to call it.
[Nexus 6P Q&A, Help & Troubleshooting] crowsnestitsupport:
That's what I did and it improved the problem but still not perfect. Still need to force LTE only mode from time to time to get LTE, also about 10-20% slower LTE speeds. Pretty sure its system related and not radio.. I flashed every single radio and the 2.15 seems to be the best but not what it was like on 6.0. I'm on AT&T by the way.. Also have FI, and I have no issues on Fi, both with T-Mobile and Sprint.
[Nexus 6P Q&A, Help & Troubleshooting] crowsnestitsupport:
Update: OK, so maybe this is completely off the wall and all wrong but while troubleshooting this I re-enabled my Google connectivity services app, ( disabled because I'm crazy that way) and updated it in the play store and it seems to have solved all my LTE connectivity issues.. Phone jumps on LTE instantly after reboots or start ups and after coming out of a no service area or after making a phone call, all of which were an issue before... No idea why... I have AT&T, with the 12/10/15 build of chroma, franco kernel, systemless root, new 6.0.1 bootloader, updated vendor image and 2.15 radio, ( not the new 2.50 one).
[Nexus 6P Q&A, Help & Troubleshooting] ultyrunner:
FWIW, not sure about others on Canadian carriers, but after rooting and going TWRP recovery, I decided to revert to stock only keeping my unlocked bootloader. I did the 6.01 OTA update and haven't had any problem with LTE. In fact, while I didn't run a speedtest much on 6.0, my LTE speeds are very fast and it connects instantly on boot or after I drop out of WiFi range. Not sure that helps anyone, but doesn't seem to be an issue.

I'm wondering if it may also be present in specific upgrade routes. Perhaps it's happening from B08K or B08M? I came from B08L to B29M OTA.
[Nexus 6P Q&A, Help & Troubleshooting] jeebuspwnz:
I'm annoyed by it, don't get me wrong. I'm just saying it's really not that big of a deal if we have to wait 2 minutes for LTE after a reboot for a month while we wait on a patch. I contributed to the google bug thread as well, because it's definitely a bug. If LTE wasn't working at all, or connections were dropping...that would be a serious issue.
[Nexus 6P Q&A, Help & Troubleshooting] pj1980:
I did get 3g after the update but my area is a bit spotty so I'm not sure if there is a connection. I turned on airplane mode, turned off and have had 4g lte since. Not rooted here BTW.
[Nexus 6P Q&A, Help & Troubleshooting] caifan:
...and Google's silence. No kind of acknowledgement that they are aware of concerns.
[Nexus 6P Q&A, Help & Troubleshooting] PieOfJustice:
Not publicly to a news site, but within the Dev forums they have. The new Nexus line is out, they don't need the heat from that. Also it's not a breaking bug. Just one that requires an extra step after reboot. The bluetooth max volume bug is the one that had me switching back to mdb08m.
[Nexus 6P Q&A, Help & Troubleshooting] 510jungleboy:
NO issues here as I'm running the new 6.0.1. I have T-Mobile and it's working flawlessly. No issue with Wi-Fi Calling either.
[Nexus 6P Q&A, Help & Troubleshooting] KeyzerSuze:
Definitely a problem here Optus Australia.

Have to airplane mode it a few times to get 4g
[Nexus 6P Q&A, Help & Troubleshooting] collinjm01:
Well i decided to take a trip over to Nexus Forums and came up with this. Have not tried it yet.

"*SOLUTION

Just got off the phone with Google and they asked me to try a few things.

>take out your SIM card

>go to settings> backup and Reset

>choose Network settings Reset, and select it.

Then power off the device, power on the device and pop the SIM card back in.

I then powered the device off and on one more time with the SIM in it.. And Bingo!

My 6p is now switching from 3G(H) and LTE on its own without needed to refresh Airplane mode.

Try this and let us know of it works for you."

[Nexus 6P Q&A, Help & Troubleshooting] dwertz:
I don't believe its a radio issue. Its the google 6.0.1 update that causes this as I am running 6.0 with new radio and no issue. Also if I run 6.0.1 with old radio it still has the same issues
[Nexus 6P Q&A, Help & Troubleshooting] wooddale:
I agree I thought it may have been radios that's usually the case but although 15 works best for me on 6.0 none of them work on 6.01 I tried all 4. Some guys in the threads jumped all over me when I said it was 6.01 said it couldn't be but it is
[Nexus 6P Q&A, Help & Troubleshooting] snovvman:
Radio or 6.0.1, let's hope the next release resolves the issue. I just rebooted my 6p 6.0.1 and 2.50 and it immediately connected to LTE for the first time. Go figure.

[Nexus 6P Q&A, Help & Troubleshooting] chrisexv6:
"Next release"?

Is that what its come to?

We have to wait for Google to do their next monthly "security update" to fix a HUGE bug?

I guess we should just look at all the emojis while we're still waiting for our phones to work again.
[Nexus 6P Q&A, Help & Troubleshooting] snovvman:
If you have a better idea or option, please do take action.
[Nexus 6P Q&A, Help & Troubleshooting] chrisexv6:
Its already been submitted as bug to Google. They are calling it "small priority"

I suppose I could say Ill never buy a Nexus phone again but its pretty apparent Le Goog couldn't care less.

If I broke something with a release at my job, I don't get a month to fix it.

And as far as a better idea...Im honestly surprised an XDA dev hasnt been able to compare the 6.0 and 6.0.1 code bases to determine all the changes and possibly narrow down which one/ones might have caused this issue in the first place.
[Nexus 6P Q&A, Help & Troubleshooting] snovvman:
So.... it appears that we are back to the option of hoping that they will fix it in the next release?

Being surprised is not exactly an idea.... I recognize that this issue is not the center of the XDA devs' universe. If someone figures out how to fix it, great! If not, I'll just be sure to get a different device next time.

This issue notwithstanding, the 6p has some really cool features to it. I, for one, will put up with having to toggle airplane mode when rebooting until it [undoubtedly] gets resolved. I'm not going to lose sleep over it.
[Nexus 6P Q&A, Help & Troubleshooting] jabbermacy:

Not that we know of. Probably let Google sort it out...
[Nexus 6P Q&A, Help & Troubleshooting] nadiros:
Since we know its not the new radio, or any of them for that matter , then I figured I'd experiment with the ROM side of things. I thought the RIL would be the first place to start. I'm no dev, so i've started with just swapping with the older 6.0 libs... So far it sticks on LTE for every boot. I'll see how this pans out and report back. If anyone has knowledge bout this stuff it would be awesome to hear from you. I swapped out 5 libs total, and only two were easily identified as RIL.
[Nexus 6P Q&A, Help & Troubleshooting] circuit89:
I am not sure what the exact issue is over here.

First 6P: Arrived with 6.0, I flashed 6.0.1 so that I don't have to wait. LTE issues came up all the time.

Second 6P: Replaced due to first 6P having microphone problems. OTA upgrade to 6.0.1 and I've been using it for last 4 days with multiple reboots. No LTE issues. Phone locks into LTE mode with no issues after reboot. Phone works as normal.

I am not sure if flashing the phone manually is the reason behind this issue.

hows the testing going? can you post the ril libs for us to try out?
[Nexus 6P Q&A, Help & Troubleshooting] jdenman03:
I'm having consistent LTE issues on my nexus 6p. Idk what's up but its very annoying. Sometimes if I toggle APN settings, it fixes it right away, sometimes it requires a reboot, sometimes I have to switch to 2G and then back to LTE.
[Nexus 6P Q&A, Help & Troubleshooting] leekslk:
this works for me post update to 6.0.1
[Nexus 6P Q&A, Help & Troubleshooting] nadiros:
So far so good here. My concern is that I haven't seen my device change from LTE to H and back...just stays on LTE. When I check in the phone service menu however, it says what it should " LTE GSM auto"

I see no harm in posting the libs I used from 6.0. Make a backup of your ROM first of course. Unzip and Drop the 6 files into /system/lib, overwriting the ones already there. I by no means claim that this is the best, brightest, or correct way to " fix" this issue, I am just posting because of your interest and in the hopes we may learn something.

[Nexus 6P Q&A, Help & Troubleshooting] PieOfJustice:
I have attempted both the Stock 6.0.1 flash and the OTA 6.0.1 at separate times and the problems are present on both for me.
[Nexus 6P Q&A, Help & Troubleshooting] ggPeti:
I have a European version Nexus 6P in Hungary and experience similar errors with LTE. I have found a reliable way to enable it though, can others try this method?

Open the "Testing" app (press *#*#4636#*#* in the dialer)

Go to Phone Information

Set preferred network type to "GSM/CDMA auto (PRL)"

Turn off radio

Turn on radio

Wait for it to connect

Set preferred network type to "LTE only"

For me, LTE is instantly enabled if I do this little dance. I also found that it not working is correlated with this log line pair:

12-24 01:30:26.056 E/PhoneBase( 4129): Error! unregisterForCallWaiting() in PhoneBase should not be called, CDMAPhone inactive.

[Nexus 6P Q&A, Help & Troubleshooting] enaybee:
Starred issue tracker. Thanks OP for initiating it.

I was on the phone with AT&T yesterday. I guess the rep ended up doing a reboot/refresh on LTE service on my phone's IMEI. She didn't tell me what exactly she did but now I am on LTE as soon as I start my phone or cycle WiFi connection. LTE stays connected. Only time it drops down to H, when I am making calls. Not sure why but this has been the case since I got my N6P. Never had this issue before on any other phones.

Something to add to discussion.
[Nexus 6P Q&A, Help & Troubleshooting] jsnmarek:
AT&T did not active VoLTE or HD Voice for the Nexus 6P which is why it drops to H when making calls. I'm pretty sure they won't support a phone that is not sold directly from AT&T unfortunately.

Here is what I did, very simple. Booted in Bootloader then recovery mode.

Then I deleted cache twice. Then factory reset and wipe twice.

Rebooted and put all my info back into the phone.

Now the connection to ATT LTE is perfect and super fast d/l speeds!

Its like night and day. Before it would eventually get LTE but the d/l

speeds were like running on E. Terrible. Now in the same location

its like lightening.

Let me ask you a question how did you get on 6.0.1? Are you stock? Are you sure when you reset your phone you didn't go back to 6.0.0? If your stock and took the ota then you might have something don't see how but never say never. I think if you just did the boot loader then returned your phone to stock you may be back on 6.0.0.
