Hello,
I recently upgraded my Huawei Nexus 6P to 6.0.1 (dirty-flash, sideloaded).
I had trouble getting LTE to work at first (turning on/off Airplane Mode makes LTE work). I kept trying to change Field Test settings to make LTE work.
However, when I factory reset it the phone won't make or receive phone calls.
It sticks on "dialing..." and it just won't work. However, data and messaging work just fine.
I forgot to back up my EFS partition so it's partially my fault.
My IMEI number and MEID show correctly, however on the My Verizon website it shows a different MEID that's nothing close to the original one. The last 2 digits were different. Neither the MEID or IMEI were changed during the upgrade process, so it should have worked fine.
I recently called Verizon Tech Support about this and they said they'd change the MEID within 72 hours to 4 days. (I called Friday evening)
They kept having issues with the server rejecting the MEID and I checked, it's not blacklisted. They told me about a "wrong form" being filled out and ran some tests and nothing worked.
The phone MEID and Field Test menus showed properly though, just calling any other number (even Verizon's activation number) won't work.
I kept factory resetting, even downgraded to 6.0 (clean flash with recovery/radios, unrooting and all that), and LTE worked better, but STILL no phone calls!
Whenever I try to activate it on the website, it keeps telling me to contact their number. I'm not sure if I'll need a new SIM card because I've tried another SIM card and will also not make calls.
I'm not sure if calling has to do with the MEID or IMEI or anything else.
Do you have any tips/suggestions to fix this annoying issue?
Thank you,
Exec360
I've seen the issue going from Wireless to LTE and vice versa but I have no issue making or receiving calls. Texting and MMS work ok also. I went from 6.0 to 6.1 by doing a factory image flash. Now I'm Chroma and I'm curious if I would have this same issue on Stock so I will probably flash factory or a slim rom stock tonight. I'm on Verizon and had a nexus 6, I popped the sim in my 6p and it activated with no issue.

Same here, except I popped out the SIM from my iPhone 5S.
Ironically, when I put the same SIM back into the 5S, calling and voicemail, in addition to data worked, even though the device was recently deactivated from Verizon.
I'd say the issue probably comes up from a corrupted IMEI/MEID or other identifier. (Not completely sure about this though — the IMEI/MEID was the same between popping in the SIM for the first time and after resetting...)
Verizon detected my device as a Huawei 1511 phone and thinks it's an old Samsung feature phone when I run it through support/help pages.
I have the exact same problem with my phone and I don't know what to do.
update: I just flashed the efs backup file and it worked again.
I forgot to back up my EFS partition and I had 2 chances to do so...
My IMEI, MEID and SIM ID show perfectly in the About section, even when factory reset and bootloader locked, but calls still don't work, very odd.
I used Wugfresh and just about every IMEI recovery tool I could find (EFS Professional) but it keeps giving me errors such as "Access Denied..." with BusyBox installed.
Still no email or response from Verizon techs tonight, expecting one tomorrow.
If not, I'll have to RMA.
More specifically, I cannot find an EFS folder or a nv_data.bin file in any file explorer — Root Explorer, Solid Explorer, TWRP, etc.
Alright, I've actually figured out that the problem is NOT the EFS after I sent it in to Verizon.
My IMEI and MEID number and everything else were actually just fine.
It wasn't flashing or anything that ruined my phone... I recently called Verizon one night on my phone about LTE issues on 6.0.1 and after that, the calls just stopped.
In fact, the problem IS on their end.
They gave me a new SIM card and it didn't work. They realized the phone was new on the network and that would cause incompatibility issues.
Now I have to ship my phone to their IT department which takes about 2 weeks.
If that is your case:
Verizon guide to getting your calling back:
First, I'd try flashing an old EFS backup when your phone was working. If that doesn't work, call their support number (1-800-922-0204) and select the tech support option or say it if it asks.
Give them your SIM card number to try activating the phone. If that doesn't work, you can still send in your phone — just ask them and a phone kit will ship.
Sending it in to the IT department will take around 1-2 weeks, so you should definitely have a backup phone or communication device on hand (you can also just use Google Voice from a PC which is a great temporary solution).
I'll say, BIG props to Verizon for giving us very good support.

AN easier method is to use any Verizon phone with a microSIM and activate on their network.
Once the SIM is active, cut it down to a nanoSIM and put it into the Nexus 6P.
It just works. All this about sending your new phone to them for two weeks is crazy.
I pulled the SIM from my LG G3 and cut it. Up and running in minutes.

Unfortunately, my other phone does not have a microSIM. NanoSIMs usually work with LTE connections.
Trimming a microSIM is dangerous and could actually damage your SIM card tray and your phone.
Thank you for the advice, but I should warn you taking that risk may actually damage or cause issues with the SIM card itself such as not being able to read its SIM card number.
EDIT:
After 5 days, 3 factory resets, and many flashes of the older radio, it has been SOLVED!!!!!
First, try disabling, reinstalling the factory version of Google Connectivity Services, then updating it in the Google Play Store.
Next, dial *#*#4636#*#* on your phone application to get to field test mode. This function will work no matter whether the phone is working or not — it's just an information screen.
Click the 3 dots and select "change radio band". Select Radio Band 6, NOT USA or Radio Band 7 — Verizon told me to try both of those and they are glitchy.
Source: "Attaching 2 screenshots. One with band 6 where calling works but data is 1x. Another with USA band where LTE data works but no calling. Looking closely it's set to emergency calls only." (http://forum.xda-developers.com/showpost.php?p=64149076&postcount=8)
Now my GSM service is working and calls work extremely well!
Glad it had nothing to do with EFS/IMEI numbers after all.
Make sure to set your APN to "VZWINTERNET" if it hasn't been set already.
I'm glad I can share this with XDADevelopers so that they can benefit from this information.

In the US, all carriers are supported for Nexus 6P use. Since you live in Qatar, you may have a different carrier.
Here are a few other points or solutions for this issue:
If your carrier is not Verizon, does your carrier whitelist the Nexus 6P or only phones sold through them?
Do you get an IMEI number in the Settings application? (don't put it here for privacy reasons) If you don't, then your issue most likely has to do with accidentally deleting or modifying the EFS partition. Try restoring an EFS backup. ALWAYS back up your EFS before you install something else or root your phone — and keep it in a safe location! Alas, that was not the case for me.
Have you tried turning Roaming on inside your cellular network settings or have a specific roaming plan?
Do you get decent reception when making calls in Qatar? Where do you have this issue most, indoors or outdoors? You should get 1x at least.
Try the field test mode (*#*#4636#*#*) in the phone application. Go to "phone info".
If you see "GSM service: emergency calls only" on Verizon, the GSM band is not connected which makes phone calls. Switch to Band 6.
Otherwise, if you see the same thing for GPRS, try switching to another band. I'm not familiar with carriers except Verizon or other US carriers (AT&T, T-mobile, etc.)
I've emphasized this a lot, but try a factory reset. Lock the bootloader and remove your custom mods to the system. It may just work for you.
The case may be that the phone service does not work in Qatar, your reception is weak, or you have a specific phone plan. It may be your carrier not being compatible with certain bands, like GSM.
If that is the case, try calling their support and ask them for any possible solutions to the problem.
EDIT:
You also stated that you bought your 6P from Ebay. Many risks can come from buying used phones off of there rather than the official websites. It's likely that someone messed with the EFS and IMEI numbers.
It could be a stolen phone too... in those cases, it would be illegal (in some countries, not sure if in Qatar) to change the IMEI number unless you have an EFS backup. Sorry, you may just be out of luck. Try another solution like Google Voice or Skype (paid) for now until you get it fixed.
Thx bro

Here in qatar, i have one friend having the same fone from amazon and it is working fine. Here no CDMA plus texting and data are working. If the efs is corrupt or as u say screwed, it would work data and text? Band USA and 6 re ok with data and text.. Band 7 dead.
In general, it may corrupt the phone function but texts/data may work fine.
Most carrier connectivity issues usually come up from a corrupt EFS or the service not being activated on your plan.
http://forums.androidcentral.com/ask-question/423732-understanding-cwm-backups-efs-partition-etc.html
For you, it seems like Band 6 is the correct one. No CDMA — and GSM is working again. Good job
Another method to try:
Update the Preferred Roaming List (PRL) - dial *228 on the phone app or figure out your carrier's PRL update number
That might work, didn't affect my calls since I don't use roaming services.
By "Band 7 dead", do you mean that the service just won't connect? My issue came from messing with the bands to fix the LTE issue and messing up my phone.
Try to call your carrier's support — try getting a new SIM card or collect information about the Nexus 6P compatibility, if they don't have it on their website.
Was the phone working since you first used it? Have you rooted or done any system-level modifications to it? Also is your carrier Verizon, because I don't think they have strong roaming service in Qatar... I am in the USA right now using Band 6, working fine.
https://community.verizonwireless.com/thread/494218
When you dial, do you get "Dialing..." and just have to wait until it hangs up, or is there static, or a carrier message? Does your friend have the same carrier (Verizon) as you do?
Sorry I'm asking so many questions. I just can't quite identify your issue very well.

Thanks for exerting all kind of possible solutions . really appreciated ... I ll explain next everything ..
First of all I'm no verizon subscriber .. I just got the phone from ebay shipped to qatar .. that's all international buyer ..
well secondly, the service is activated. here is different than yours in activation process. Plus my sim card is working on all other devices, opo, op2, opx, mi redmi n2, moto g ...
I believe the problem remains in the piece I have now (nexus 6p) because im used to buy phones from the US and they work fine expect some missing LTE bands that does not really interfere with calling service.
If the EFS/IMEI is corrupt, will it register on the network normally? will data and text still work?
Band 7 dead means no text no data and surely no calls ... plus when I chose it, i always get called ended right after i press Dial a number
experience with other bands:
band USA: text and data working fine ... calls: when dialing, it keeps dialing until the network fails and returns again like reconnect (the bars disappear and return again) and when i hang up, it respond quickly and execute the action but on,
Band 6: text ok data ok , calls no .. but when dialing, it keeps dialing normally till it gives me (call ended ) and if I try to hang up after few seconds, it freezes the phone for like 10 seconds till it execute the action of hanging up ...
so the USA band is the most responsive band in terms of hanging up ..
when I dial *#4636 .... , and access phone information to change preferred network, it is usually set to LTE/CDMA/GSM (PRL) >> if i try to change it to LTE/GSM (PRL) because no CDMA here, it usually return to the default after restarting the phone .. it does not really change the network if, for example, I choose GSM only .. I still see LTE on the bar .. moreover, when i try to choose 2g from cellular networks from settings, it does not reflect and I still get LTE working .. weird ..
** in all cases, FYI, I always see the carrier name in the top left corner of the screen.
*228 does not work as Im not verizon .. plus any USSDs are not going through as it gives error "connection problem or invalid MMI code"
when I try to access caller ID, it gives error " network or SIM card error".
I tried to call the carrier but they could not do anything. I'm still expecting a call from their back office team who ( i assume ) has more experience
getting a new sim would not help because I have tried different active sims different numbers and I also tried the second carrier here in Qatar (vodafone) and the problem persist.
the fone never worked since i reached Qatar. It was not rooted. I only unlocked BL and flashed the first factory stock rom (fully including the radio), yet nothing
wait wait please don't lose hope
one friend here is also giving me ideas and solutions to get over my isssue, he suggested i flash chroma rom bcz it has more bands. I will flash it and give a feedback.
I really appreciate your efforts and also his efforts @Soulfly3
pardon me if I wrote too many things and for giving all my trials not in order
Thanks
Thanks everyone for helping me resolve my issue. biggest thanks goes to @@scoobysnack who helped me greatly to get over it.
Installing Chroma ROM solved the issue because basically it was a problem of bands. Chroma had more bands that work in Qatar. and I could return back to stock rom again without any problems ( but don't mess up with bands in phone information )
Thanks @Exec360 for offering me your great support >>>
I told you chroma would solve your problems. it has different bands to select and I figured the "AUS" bands would work.
Any advice for those of us operating on Verizon's extended network? I'm using my device on the Appalachian wireless network (with whom Verizon has a network sharing agreement as part of it's LTE in Rural America program), and I'm constantly getting the roaming indicator, even though I know I'm not roaming. I've never dealt with this on any other device, and I've used 4 different devices encompassing both Windows Phone and Android. If I switch the CDMA roaming indicator to "Home", the roaming indicator disappears and the usual LTE indicator appears, but I'm unable to make voice calls. If I switch the roaming indicator to "Automatic", I can make voice calls but the roaming indicator returns and the device tells me I'm roaming inside the test menu, even though Verizon tells me I'm not incurring roaming charges. If that's true, then the roaming indicator is just an annoyance, but it's there constantly (even when on WiFi) and for me it's a significant annoyance. Is there anything I can do, or is this just something I'm going to have to live with?
This is probably something silly and small but I'm pulling my hair out trying to fix this. I bought a G4 play XT1607 unlocked from Best Buy the other week. I also purchased a tracfone SIM activation kit. The kit had 2 sim cards, one GSM and one CDMA. Since I used Verizon service previous to my foray into prepaid plans, I activated the phone with the CDMA SIM card and registered the IMEI with Tracfone. Then I was able to successfully unlock the bootloader following the motorola official procedures, put on TWRP and flashed a LineageOS ROM w/ SU and OpenGAPPS. It worked fine for a couple of days and then *poof* my internet data would no longer connect at all. I rebooted several times and got nothing.
I then saw that there is some LTE/wifi handoff bug and I figured, no biggie, I'll swap my tracfone service to the GSM SIM and pop it in and it'll be good to go. Not so. At first, in fastboot, the screen was saying <Baseband not found> and I couldn't even place a phone call. The phone still doesn't seem to recognize the SIM card and doesn't show any cellular connectivity. I've tried flashing AOKP, LineageOS (both 7.1) and the stock 6.0.1 deodexed several times. I've tried this thread here and using it's 2.35-1 Radio file with the above ROMs which I installed using TWRP as well. None of this is seeming to work so I called Tracfone and they said it should be working and must be on my end. So following this I decided to go fully to flash fully back to stock. I used this file:
https://mirrors.lolinet.com/firmware/moto/harpia/official/RETUS/
and followed these directions
https://forum.xda-developers.com/g4-play/how-to/guide-return-to-stock-firmware-recovery-t3551797
Phone seems to be working fine other than not getting any kind of cellular signal. Even though it should be "factory fresh now" When I called tracfone they didn't seem to sure of themselves and told me it would activate within 2 hours and to call back if I had issues. It's been 4 hours now an dNo sign of signal. Did I mess something up here? Does tracfone need to do something on their send since this phone/IMEI was used previously on their service as CDMA? Or can I just "pop the new SD card and go" Or do I just need to add something like APN settings or similar to get what I have working? I don't want to call tracfone again if I don't have to because they didn't seem to know what to do when I explained it to them and sounded incredulous that one phone did both CDMA and GSM to begin with.
Can anyone help me? I'd like to use this GSM SIM card in my unlocked XT1607 (RETUS). This phone was previously on the same tracfone account with the same phone number but on their CDMA network. What gives? Is this something I messed up or tracfone needs to deal with?
I did some more research and I'm pretty sure this is on Tracfones end. I believe they still have it registered as a CDMA device and it's ignoring my GSM SIM when I turn it on.

I don't think that's the issue. Did you set an APN for Tracfone? With the GSM SIM, you have to configure the APN.
Tracfone's site says to go to apn.tracfone.com but that site gives an error. I did find this: http://apn-settings.com/tracfone-apn-settings-step-by-step-configuration-guide/
Or you can check on Howardforums or Turks.
Also G4 Play, also Tracfone BYOP. I, however, did GSM from the getgo to avoid something like this. On my phone, when I installed Lineage, my MEID disappeared entirely (it only shows my IMEI in settings). SIM card reads just fine and APN settings are fine. I do think the initial ROM you installed inhibited the device's ability to read its own MEID (everything hints at these ROMs being made specifically for dual-SIM GSM phones). However, switching to the GSM SIM should have worked, provided you actually transferred your number and didn't just pop the other SIM in (the MEID on the Red "BYOP" card would have needed to be decommissioned).
Here's a thought: Try dialing *22890 on the phone. If it says the phone is programmed for CDMA service, then that could be part of the issue. Also check Settings to see if you have both an MEID and IMEI, or just an IMEI. If your IMEI is 0, then the SIM Card is not being read and they need to ship you a new one.

Just to follow up, I did find the correct web page for Tracfone APN: https://www.tracfone.com/apn
Posting for reference. APN is RESELLER/reseller.
I am currently in India, and trying to use my Essential PH1 with a Vodafone India 4G sim card. The SIM is not registering with the phone, and I am unable to get any network. I keep getting the message "your SIM is not allowed to use this network". I have tried contacting the local service center, but they tell me that the handset settings need to be changed. The same SIM works well with other phones in India.
I am using a Vodafone India 4G sim.. its a 'postpaid' connection (if that matters). When I manually select the network, all the available networks are listed, when I select "choose automatically", a message pops up "already registered on the network", but i dont get any signal.
When I manually try to select Vodafone IN from the list, pop up message says "your SIM is not allowed to use this network"
I have checked with Vodafone customer care, and they are sure its a phone config issue.
The same SIM works perfectly fine in any other handset. (Currently running the same SIM in Nexus 5)
Since this phone has not been launched in India yet, there is no technical knowledge or troubleshooting database available locally. Would you be able to help me with the correct settings so that the I can continue using the phone in India?
HI
I am having the same Issue with my phone, just bought it from US. indian SIMS not registering, were you able to find a solution for this?
Thanks
No.. not yet. The Essential customer care was supposed to get back, but they are not responding since the last couple of days. Do keep in touch if you are able to find a solution...

Hi
Received an OTA today for the device, Airtel and Vodafone are now registering ,. Jio is not able to register.
Cheers
I'm having a similar problem in Japan with Softbank, which ironically bought Sprint - the sole carrier of the phone in the USA.
There is no signal at all, and when selecting Softbank manually from the list of carriers, an error message stating it can't authenticate on the network popped up.
I faced the same issue a week ago, with both Airtel and Jio not registering the device on their networks. Yesterday, I booted up the phone again, installed the OTA, and was on my way to the Airtel store to talk about it. When I put in my SIM and turned it on, it got a signal and LTE data. I didn't try the same with Jio.
The most likely reason for the phone not being detected initially is that Essential has just one SKU, as far as I know, with all IMEIs of the 99x series. That's the typical IMEI series for Verizon and Sprint in the US, which are CDMA networks. Most other GSM IMEIs are of the 35x series.
I had planned to contact Essential support about this, but I didn't get down to it. I'm not sure what exactly made it work the second time. Maybe the OTA update changed something, or maybe Airtel took a while to auto-register (whitelist) the IMEI of this phone after it first detected it being used with a legitimate Airtel SIM. Regardless, it works just fine now.
NOTE: After I was able to get a signal, I could see the LTE symbol with no internet connectivity. I changed the preferred network type to "Global" in Settings and then it worked just fine. The default setting of LTE/TDSCDMA/CDMA/EVDO/GSM/WCDMA didn't allow data, only calls and SMS.
Yes am too facing same problem with essential PH1
used all operator Indian 4g / 3g sim card
even cdma also ...no result ...no network
Product Name -Mata
Variant Openus
Baseband 2.0.c4-M1.2
Secure boot Yes
Device State Locked
anyone some clue ???
regards,
When using outside of the U.S.A change network type to Global. Secondly insert the Sim (with the phone turned off). You should receive service when you turn the device on. In case you don't, give it a moment.
I had to replace my Sim as a last resort and then it worked without a problem.
Good luck.

Does it say Sim not present? If not, go online and search for APN settings for whatever network your on and enter them in as listed. On the screen you posted, click "access point names" and transpose the data from whatever your carrier's APN settings.

Can you raise this in guide section ->uicc unlock post. you can ask for modem partition from someone who has openus variant and can flash those ones. Did you also check your sim in another phone

Maybe i dont understand but it looks as if you have 2 APN settings profiles yet you don't have either selected.

My phone is somehow locked for Sprint after the September update even if I have an unlocked variant (OPENUS)

I glanced at these but didn't read the whole threads. Pretty sure they address sprint sim card locking post update. It may be worth reading about to see if yours is a similar situation. Good luck man.
I'm kind of in the same boat, essential phone openus variant with no service. I've tried different things and have been able to get it to work but just for some time before it gets no service again or some odd behavior. I don't get invalid sim or no sim notification, it is a no service notification, apparently it recognizes SIM and accepts it but is not able to find a network, as if it were out of coverage or mobile radio off. SIM card has been tested in another essential phone at same location and works flawlessly.
So far I've found that if I downgrade software to nougat and then update to oreo or pie, and then insert SIM, phone is able to get LTE connection, receive or make calls, it works fine. But then after a couple of hours or even half a day, it gets no service again. Network or factory resetting doesn't do anything, changing network settings neither,then after If phone is restarted with sim in or if sim is inserted while on, it immediately shows voicemail notification but there is no way to retrieve it of course.
Most of the times at network settings it gets and shows the correct apn but it doesn't let to choose network manually, it turns back to automatically and says no networks available. Some times I get a rare relation with wifi connection, if wifi is on and connected it shows carrier name as if ti was connected to network but no calls in or out, as soon as wifi is turned off or disconnects, carrier goes back to No Service.
Maybe someone knowing this has some idea of why phone has this strange behavior which makes it useless as a phone.

I think your phone locked for Sprint like mine , call them to unlock it .
mine is unlocked From Sprint now , but i sill need a Sprint Sim to complete the unlock process which i didn't get yet , I don't know where i can get one (I LIVE IN MOROCCO)
I guess it's possible but I really don't think that phone could be locked to sprint. I understand although sprint variant is supposed to be locked, most users are able to use other carrier sim, and only the pie update has shown invalid sim, which is not this case by the way.

mine is not a Sprint variant , and somehow is locked to Sprint , it was previously purchased From Best Buy . but after installing Pie on it , it shows no service , i called Sprint and they said it's locked to them
than i made an unlock request and they unlocked it
ok, so maybe flashing modemst images for openus variant could solve the problem, I don't mind trying if they come available but haven't found them yet.

Hi everyone.
I bought a V20 T-Mobile version H918 on eBay. Seller claims it's carrier unlocked. As a precaution, I bought a $10 Red Pocket prepaid SIM card to test it with (because my current phone is CDMA). First, I tested it with Red Pocket's "GSMA" sim card, which uses AT&T's network. When using this SIM, the phone mostly didn't work. Out of 30 tries, I was only able to make a phone call once. All other times, I got no dial tone. And I wasn't able to receive data at all. APN settings were correct, verified with Red Pocket customer service; also tried many other APNs I found on google, but they made no difference.
Next, after doing a factory reset, I tried Red Pocket's "GSMT" SIM card, which uses T-Mobile's network. When using this SIM, all services including calling, texting, mms, and data work perfectly. Although, despite it working, the phone is using the wrong APN (fast.t-mobile.com). This seems to be a hard default setting, and the phone doesn't allow me to select a different APN while this SIM card is inserted.
Red Pocket tells me that an unlocked phone should work fine with either the "GSMA" or the "GSMT" card. So, their advice, together with the fact that the phone isn't letting me change the APN when on T-Mobile's network, leads me to believe it might not be unlocked. How can I know for sure?
Note: IMEI registers as clean in the database. Also, the IMEI in settings, the one shown by dialing *#06#, and the one on the sticker all match.
Thanks!

If it was locked, I don't think it would have accepted the ATT sim at all. You can try playing around with the Device unlock app, but on the first screen it seems to pretty much always claim its locked for me
On my (pretty sure its unlocked, havn't stuck another sim in it almost since I got it months ago)
H918 that's running on a T-Mobile (proper, not mvno) sim I can freely add and switch between APNs
Keep in mind that the H918 isn't going to be good on ATT's network.

Thanks for the reply. You're saying if it were still locked, it would give an error message with the AT&T SIM?

right, if it were locked, you wouldn't even get 1/30 phone calls to work, you'd get like invalid sim or something. Locked means it wouldn't even try to use the other sim.
Happend to find a video of someone with a simlocked h918 unlocking it, it shows networked locked where the carrier name goes.
