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...
Hi everyone. I just want to ask a question about my s3. So here is the scenario:
I brought my s3 locked to rogers to a CP technician and asked him if he could unlock my s3, he then told me that he can unlock it even though it is in 4.3 firmware. I don't know what he did but the only thing that I know is that he upgraded my s3 to 4.4.2 and he also rooted it. When he gave it back to me, I can already use any sim card so I guess that the unlocking is successful. The problem occured when I got home, my phone says it is in emergency calls only so i tried to toggle airplane mode on/off if it would fix the problem and it fixed it, I can call my phone again but then after 30 secs of toggling airplane mode to off, it would eventually cant receive or make calls or text. But when i toggle airplane mode on/off again, it can receive or make calls and texts but after 30 secs the problem occurs again. I go back to the CP technician to ask him what's happening but when I'm in their area, the phone works like a charm. I don't even need to toggle airplane mode on/off. And it can also receive or make calls/texts in their area. But when I go back to our place the problem occurs again.
BTW, my ImEI is still the same at the back of the phone if this info is needed.
Thank you everyone and i hope my problem will be solved.

You can flash a stock Rogers ROM. After that, you can install Philz Touch recovery, backup your current ROM, flash another a custom ROM (I like Liquidsmooth), and try it out. If you want to go back to stock, boot into recovery, and restore your backup.

Hi sir, I found out that I'm on the latest firmware already, it's 4.4.2 already so i don't need to get it from sammobile already, will i just skip the flashing on stock rogers rom step and proceed already in installing Philz Touch recovery to install a new rom. Thank you so much sir.
Connect via wifi and install any ota updates. Then install philz and a custom rom. You may also need to install gapps if they are not included in the rom.
Hello everybody! I have a problem. When I am in 2G network, network signal is good, but no one can call me. SMS is incoming and internet works. But no calls. Sometimes and me can't even be able to call. What is the problem? With 3G network no problem.
Device - T999N.
I live in Uzbekistan. Operator is Beeline Uzbekistan.
Is the phone running the latest bootloader and modem? Which ROM is installed?
Modem T999NUVUBOH1.
Now installed RR от d2att. But I've try CyanogenMod, LiteRom, OctOs. And STOCK that was, I do not remember.
And what do you mean with the bootloader?
The bootloader is what allows the phone to boot the ROM. It's similar to a computer BIOS.
This happens on the stock ROM too?

Bootloader is not the kernel. The Kernel is part of the operating system.

And it will not break unlock?
The simplest way to update everything on the phone would be to flash a stock ROM from sammobile.com. Flashing a stock ROM should not re-lock the phone to a carrier. I have used several Samsung phones in the past and, once the phone has been network unlocked, it has stayed unlocked.
Before flashing anything, confirm the phone's model # in download mode.

I'm sorry if this has been asked and answered, I did a bit of searching but didn't find an exact answer. Maybe I'm getting two narrow sighted in my search, but anyhoo! I ordered a Pixel Xl 2 unlocked from Google. My question is if I pop a verizon sim into the deivce, will updates or any changes cause it to lock the bootloader. Should I unlock the bootloader to make sure it retains it's unlockable state or is it fine to pop in the verizon sim with no worries?
I am on Verizon also, and I too ordered the Google store unlocked version just so I could unlock bootloader when I got my phone. What I read and did was boot the phone WITHOUT SIM card connect to WiFi, skipped the setup, and enabled developer options to be able to unlock bootloader, unlocked bootloader and then I put the Sim card in and continued to set my phone up. If I were you, I would also do the unlock_critical command as well since it will also wipe data. I was unaware of that when I did mine. So future wipe is necessary for me.
Edit: wording
I used my pixel xl witch I ordered from Google on verizon for 2 months last year before I decided to unlock it and had no issues. If you concerned about it just unlock it now. If you not as worried but still think this could happen just manually side the update from Google every time a update is released just remember to remove the -w from the flash file and then you are ensured that it will flash all the unlocked able software!

Same here, ordered the 2xl from Google, unlocked version. On Verizon. Unlocked the P2XL before putting the sim in (I did both bootloader and unlock_critical). Popped in the sim. No problem.
However, I would agree, and assume (again, didn't test this) even if you put the sim in first, you can still unlock, it's just that it won't ask you for WiFi when you activate the first time, it will simply use the LTE connection to connect.
The SIM controlling the unlock in the Pixels is an urban myth that just won't seem to die.

I haven't flashed anything whatsoever, all I did was get the device, open the case, charge it, unlock the bootloader (and critical), then set it up, then put in my sim (may have put the sim in before I set it up, can't remember, but definitely unlocked first, to be safe).
Is there an advantage to using the Verizon Radio Image? Does it give us something we don't already have? I'm getting expected LTE speeds (~18-20 mb/s down, ~4 mb/s up) with my phone so far...?

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
