thats the way it is for now- I do not condone changing esn numbers but I have confirmed I have repaired a few that lost signal do to esn changes- currently is no way to modify esn and retain any signal on the sprint model and on the us cellular it will work but without 3g

well thanks ...imma use my s5 like an ipod lol
please if anyother knows how to fix my problem
Any solution so far?
Were you guys able to get this problem solved?
Right now I am in the same situation.. if I change ESN/MEID I lose signal and I can't seem to change the IMEI at all .. DFS shows that it changes but after restart, only ESN/MEID is changed, IMEI always stays the same. I beleive that is the problem because ESN/MEID and IMEI aren't matching somewhere in the code.
Please do let me know if there is anyway to get the signal back.
Thanks!
Hi I am also looking for the same solution to this issue. Any luck?
If anyone have a solution please help!
What things have you guys tried? Only things I can think of right now is messing with IMEI repair and trying out different PRLs.

I am having the same issue. Im positive if we could change the prl it would bring the signal back.
Got 3G no voice
Hi I am in the same situation but i can get 3g with original esn but i must change esn to get voice since i'm outside usa
the answer is the Baseband.
I have a Sprint Note 3 & every time I've tried to update past the MJ4 Baseband, I lose signal.
I Flashed it to Boost & I've also tried manually flashing the PRL, still a no go.
my advice is to try downgrading the Baseband.
I have a SGH-I337 (AT&T) that I'm trying to get to work with a Verizon sim. I followed the steps in the post below.
http://forum.xda-developers.com/gal...aranteed-free-sim-unlock-mk2-nb1-nc1-t2852979
I follow the steps as stated but at the end the phone has no signal/loses signal using Verizon sim's.
Usually after a fresh boot, the phone will have bars but no data and cannot make calls. The phone states EMERGENCY CALLS ONLY at this point. After a few minutes the service bars will disappear and be replaced with a NO SERVICE indicator.
The phone no longer indicates an invalid sim, but does not auto load APN settings. Manually inputting the Verizon APN settings does not fix it either.
I have checked and it does NOT show the NULL IMEI on the *#06#. Also with the Verizon sim the hidden menus don't always function (*#0011# and such) although I've read that is an AT&T only thing, I'm not sure if that true.
When I insert an AT&T Sim it gets service/data immediately upon booting. I've also tried two different Verizon sim cards.
Thoughts or Suggestions? What am I missing?

I don't own any Verizon phones myself, so I could be totally wrong but:
- Verizon's SIM cards are just for data.
- Verizon uses CDMA (Your subscriber identity is in the ESN/IMEI)
- AT&T uses GSM (Your subscriber identity is in the SIM)
Both networks require you to authenticate yourself with your subscriber identity before they will give you data access.
Sounds like Verizon doesn't have your IMEI, so the phone fails to authenticate/connect.
Try calling Verizon, tell them you got a new phone, and you would like to tell them the IMEI of the new one, so that it can connect to data services.
Either that or they need the number off the Verizon SIM

It should be able to work with CDMA. I've seen the option in some of the menu's I've been through. And the guides have all said that they can work between AT&T and Verizon/T-Mobile or vice versa.
Also, AT&T will unlock the phone for you if you go to their website and fill out the stuff. The only reason I didn't do this is because I'm still under contract and I would have to break that and pay the early termination fee.
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?
Hey guys,
I bought the G950FD on eBay so that I could root and tweak it the way I always have with my previous phones. I use total wireless which is on Verizon towers and have gotten the phone to connect just like it should, text, receive/make calls, and use data. To do this, I used the Flashable CSC Collection here to switch the CSC to VZW and it worked for a while, but after restarting I started to get some problems that I can't sort out.
1. Calls do not work anymore - I can't make or receive them at all. Dialing a number just says "Dialing" with some zeros below it, and calling my number goes right to voicemail.2. Data cuts out sometimes and shows no signal. Recently, I tried to search for carriers and reconnect to Verizon but now I can't get a connection at all without restoring a backup.3. Other observations: Using a signal info app, it seems like I only see band 1 and it is usually very slow. CDMA obviously doesn't work, so maybe that's why I can't register on the network anymore, but why did it work when I first booted up? I can't change the APN settings after switching to VZW CSC and also can't see an option for VoLTE, but that must be working right? Only some ROMs seem to work with the VZW CSC and allow me to connect to the cell towers. Changing the network mode does not do anything and just reverts back to 2G, which doesn't make sense because 2G shouldn't be possible. None of the codes that can be entered into the dialer to run the activities have worked or helped at all. When connected to WiFi, the no signal bar shows 4G connectivity and the signal bars reappear but I am still not connected.
So, what can I try and does anyone have knowledge to share about cell towers, SIMs, registering on the network, or anything else relevant to my situation? I am completely stumped and would love any input that you guys could give me and future 950FD owners who might have this issue.
I'm looking forward to hearing what you guys know,
Joe
Only verizon phones work on verizon, you can't use a non-verizon phone on its network even if its supports its frequencies. Lte on your s8 is compatible with verizon's but after it worked for a bit they disabled your imei from their network, nothing you can do about it.

Thanks for the reply! I do not think they have blocked my IMEI because I just restored a backup and everything works again. I believe it has something to do with the settings on my phone or possibly a bug with Android/changing the CSC because changing the network settings cause crashes, disconnects, and other weird behavior.

Lol don't give misinformation, they don't do this, in fact I'm pretty sure forcing all users to have phones obtained through Verizon would be completely illegal for a Telco to do. VZW doesn't even know what type of phone you have unless you register it and even if you do they don't care.
