Cannot connect to LTE (doesn't matter what rom i'm on) - Google Pixel XL Questions & Answers

Hi XDA, I have an unlocked pixel XL on verizon network. I cannot connect to LTE or anything other than 2g networks. I have clean installed, changed APNs and tried everything to properly get the LTE back. Help?

I mean this is gonna sound dumb but have you looked at the mobile networks setting page and have your preferred network on LTE?

Yes

Can you change the network operators on 8.1?

Is your unlocked Pixel XL from the USA? It seems it doesn't support the correct bands for your network

All pixels have the same radios. Dial *#*#4636#*#* click on phone info. Change settings if needed

SIM card is toast. I have had this exact thing happen to me. Just go into a VZW store and request a new one. Sim handshake needed for LTE connection only on VZW.

After you got the new sim and installed it did you go back to factory rom and waited a bit for it to connect to the network?

I'm on the February patch, stock. I'm flashing everything, also, is it normal for your phone number to not be your phone number with a new sim?

My number showing up on about phone is 908-770-6054. This is not my number, could it be human error?

Contact your carrier or go in and tell them that it is not your number and that you are stuck on 2g they should be able to tell you how to fix it or if you go in they can fix it

I did contact my carrier, they cannot figure out what to do. Replaced the sim about 4 times, still no luck. I go into testing (secret code) and I am on 1x network @loeffler23

Sounds like your efs data could be corrupt and there is no way to fix that. Or your LTE radio is toast. Did someone try to carrier unlock your phone?

my phone's unlocked by default and there has to be a way to fix efs, not accessible by recovery? (what is efs)

It holds the imei and other radio proprietary info not sure what partition that data is actually in on this device. I think the efs data is no longer in /efs
Twrp used to have a option for efs backup with the data system backup and restore options

[Q] foregin sim card not prompting unlock galaxy s2 t989

I'm trying to unlock my phone, I bought used on ebay, I found found a thread here that shows you how to unlock, but can't even do the first step. when I install a different sim card, I don't get the message Unlock, the phone reads the sim as a non support sim.
the sim I'm putting in the phone doesnt have service on it, Is this the reason the unlock message doesn't come up?

I put a metro pcs sim that has service on it, but when I try to make a call, it say, not register to network, and or mobile network disconnected? Aso also tried to put the apn setting, but when I try to save the apn setting, they disappear??
Anyone have any idea?
Thanks for the reply
you can use free unlock from general http://forum.xda-developers.com/showthread.php?t=2024514
but of course you have to do it from uvkl1. but--you can do a nandroid, and after you unlock it, restore your backup! it will stay unlocked

Seems your phone's ROM/Radio mismatched or not for MetroPCS. This exactly happened to my phone also, until I flashed a new radio for my rom(I am using TMobile, flashed new TMobile ROM but not new Radio. Then it had the problems as you have now).

The sim card I was putting in the phone was already register to a different phone.. I had to put a new sim, not active yet, then register the new sim to my imei and it worked fine.. I bought the phone used from ebay and it was already unlocked..

[Q] no radio after flashing ROM

so i installed TWRP on mu unlocked and S-OFF phone, and rooted the phone. then from the recovery, i made a nandroid backup, wiped the phone, and installed this ROM. even though all traces of Verizon software is now wiped off the phone (i hope!), it still only connects when the Verizon SIM card is in (and it shows the Roaming sign; fyi, i am in Canada now). it won't give me a voice nor a data connection with my Telus SIM card nor with my Rogers SIM card. so, i went into recovery, wiped cache, and afterwards, the phone was stuck in the boot...i had to go to recovery again, wipe everything, and restore my nandroid backup. the phone is now back to stock Verizon software, and it still only connects when the Verizon SIM card is in. it should at least give me voice connection with the Telus or Rogers SIM card, but it won't. something must have happened to the radio when i flashed the ROM, and i can't figure it out.
do you guys have any troubleshooting ideas? can anybody guide me towards a fix/troubleshooting method? i'd appreciate any help...

This ROM is still very early and has some bugs. Making it work for people not using it on Verizon isn't a concern of Santods at the moment. Switch to something that does work for you until he gets the rom further along.

thank you all for your help. it's not just APN though; with that ROM, i cannot even have a voice connection, let alone data. and even though i restored my stock backup (and now running the original ROM that came with the phone), the voice still doesn't work; it only functions with a Verizon SIM card.

Well.. when you were on cm you couldn't get any service? Is your carrier lte/cdma or gsm based? Are you showing global mode when on cm? It also can be a case where some qpst work needs done to enable the extra radio bands needed to pickup your carrier.

i'm guessing by CM you mean CyanogenMod, right? if so, i was never on CM. i was using the stock ROM (4.4.3, Sense 6.0, Verizon bloatware), and then i flashed the Lollipop ROM by santod. the phone initially could connect to Rogers and i had voice and very slow (i.e., EDGE) data speeds, but after flashing the ROM, my phone lost the ability to provide any sort of voice connection except when i'm using my old Verizon SIM card (that shows the Roaming icon, because i'm in Canada now).
i could try CM, if you think it has less possible bugs. do you suggest i do a factory reset while on stock ROM and then flash CM?

Yes. Factory reset on stock recovery. Then flash twrp and sideload the latest cm build. I would probably stay with cm11 for now too.

Well you can do a factory reset on stock Rom and let it boot up and then copy cm over to phone storage for flashing.....or...adb sideload.
When you boot into twrp under the advanced options there's an adb sideload feature. Once the phone is in this mode you can use you pc to send a Rom over using the command "adb sideload nameofROM.zip". Your pc will send the Rom over and the phone will flash it once it's copied over.
Backup the internal sd card of your phone before you factory reset. I've forgotten so many times it isn't funny.

ok, i did all that with MDMower TWRM 2.7.1.2 this time. CM11 is up and running now, but i still have the same issue. my Telus and Rogers SIM cards lead to a "No Service" icon, whereas my old Verizon SIM gives the Roaming indicator. funny thing is that with all three SIM cards, the correct set of APNs is loaded by default when i boot the phone, but selecting those APNs don't change anything. i also tried Global, GSM only, WDCMA preferred, and some combinations of those modes to no avail (the only SIM that leads to service is Verizon's). it seems like the phone is hard-coded for that particular SIM card, no matter what.
any other ideas? could the radio have become corrupted somehow during unlocking/S-OFF'ing/flashing? if so, what is a workaround for this?

I would bet they are using a frequency that's not currently unlocked on your radio. There is a lengthy how to posted on Google about how to enable Qualcomm radio bands.

aha, great! i know that Verizon HTC One M7 uses
CDMA 800/1900 MHz
GSM/GPRS/EDGE 850/900/1800/1900MHz
UMTS/HSPA 1900/2100MHz
LTE 700MHz (Band 13)
according to this Wikipedia page, Telus has a HSPA+ network on 850/1900 MHz (so at least the 1900 Mhz band should give me something, shouldn't it?), it has CDMA service that's supposed to shut down completely in 2015 (it is out of service in some places in Canada, but i'm not sure about my area), but has no GSM service at all.
thanks for the tip about enabling radio bands; i'll search for it...

[Q] I747M - Telus - Won't connect to network - Weird

Hi everyone,
Weird issue with my telus locked S3. When searching for networks it only shows EXT, and nothing else. Is my phone hooped? I already tried a fresh factory restore to stock. Checked blacklist and its not black listed. My SIM works in my S4 just fine. Hallp?
Does your phone show the correct imei when dialling *#06# on the dialler?

great question. It does...but with a /11 after it.
That's fine. It's the first 15 digits that represent the IMEI.
Have you tried changing the network settings to wcdma only?

Well i reflashed I747MVLUFOB1, and the weird thing is i had to do a factory reset on the phone for it to give me the default setup (when i flashed it..it seemed like it didn't delete everything). Now at least its showing "bars" of service..but will only find the EXT network (and i do mean cellular network here).
Any other ideas?

On a side note, seems like it won't connect to telus, but it will connect to Fido (and will roam on rogers with my international SIM). IMEI is not on the national blacklist..maybe its not the phone?

I am experiencing the exact same problem as you My problems also started after I installed the I747MVLUFOB1 (BMC/Bell version) on my Bell locked phone. Mine was a little more complicated in that I had also lost my IMEI and I had to restore my IMEI. My IMEI is now restored, phone is not blacklisted but same issue of only having EXT as a network option. If you figure it out, please let me know how you fixed it! Thank you
Hmm very strange. Well i did check the IMEI several times (along with the person that brought it to me) and couldn't figure it out so i had to give it back unfixed. I didn't end up figuring out, but i did hear of another scenario..exactly the same with an S5 they had. Wonder if there's a lot more people with this issue out there?
This tutorial saved my phone! Luckily I had a friend with the same phone.

Question SIM not working after EU V3.23 Update

Hey guys,
yesterday my phone got updated to the 3.23 Version. Since then my phone is getting no signal to my provider nor mobile network.
I tried WIPE USER DATA which also doesnt work. The sim works fine in my iphone xs...
I also tried to manually apply APN settings.
After i plug in the SIM card it asks for my pin. I enter the pin and it unlocks the SIM but no signal.
I only get a Question Mark at the Status Bar.
Do you guys have any similar problems?
Greetings from Germany
