N6 - Unable to make/receive calls (4G/SMS working fine) - Nexus 6 Q&A, Help & Troubleshooting

Hi dear Developers,
Recently i've purchased an used Nexus 6. When i insert the SIM, it recognizes the phone carrier, i get 4G network working fine and SMS also. But i can't make/receive calls.
The previus owner sad that only a few carriers worked. I ignored it because i tought i could solve this by flashing the N6 stock image. But i already did that and the problem persist.
What could it be ?
I've already flashed :
5.0 (LRX21O)
5.1.1 (All carriers except T-Mobile US) (LMY47Z)
5.1.1 (For T-Mobile ONLY) (LYZ28N)
5.1.1 (For Project Fi ONLY) (LVY48I)
6.0.1 (MOB30D)
6.0.1 (MOB30I)
Please help me! I've spent more than 1 month of my salary.
Thanks to all! :good:
:highfive:

Was it blacklisted? Is it complete stock? I mean if you flashed complete stock then its probably a board.
Edit: did you wipe data and cache?

what do you mean with "blacklisted"?
Yes, I guess it was complete stock (I downloaded directly from google developers: https://developers.google.com/android/nexus/images).
I wiped cache and did factory reset after one of my many stock flashes.

If the original owner knew that the Nexus only worked on a few carriers, that is a sign that the Nexus' IMEI has been blacklisted on certain carriers in your area. In other words, the original owner neglected to keep up with the payments on his device, and thus the carrier has blocked the device's access to the network. While it could be a fault in the mainboard, the fact you can receive a 4G signal means the SIM card tray is functioning properly along with the radios, making it unlikely to be a hardware fault.
Contact your carrier. Give them the IMEI of the Nexus, and they will tell you if the device is blacklisted. If it is, find a different carrier or else try and get your money back.

Yep just like Strephon said it is always good to do a swappa check before you buy. If its branded to a carrier which its not (being a nexus) then I usually ask the former carrier if it was blacklisted before I buy.

Is it possible to use 4G and send SMS even with a blocked IMEI?
I tought it wouldnt recognize my SIM if it was blocked.
There is any possibilities to remove my IMEI from the blacklist?
(I know it shouldnt help, my carrier here in Brazil is VIVO)

No. And neither 2G nor 3G will function, so forget that.

Either pay the bill yourself, or get the seller to pay the bill. It's highly unlikely that the seller will pay up here, and paying the bill yourself is foolish. I would start looking at alternative networks to VIVO, assuming that VIVO has blocked your IMEI. The only way you will know for certain that VIVO has blocked the IMEI is by contacting them.

So that is why I'm thinking thats not an IMEI problem.
I'm getting normal 4G signal. I can browse the web and send SMS too.
The only thing that I cant do, is send/receive calls.

Then you need to check the APN on the Nexus and make sure it is correct. Here is the one for VIVO.

[Q] How can we enable(trick) Sprint HTC One for Domestic(US) Sim use (data only)

After many conversations with HTC and Sprint it appears Sprint has locked out the ability for use of domestic data cards from competing carriers on their sim capable devices such as the HTC One. It is the consensus opinion this should be an unlock-able option to ensure fair competition of market provided the user is not under contract and is in good standing with Sprint/Carrier. This is currently in Legislation and backed by President Obama. There are also over 115,000 petitioners so far.
I am not under contract, in good standing(paid) yet Sprint says they "can't" enable the use of a competitors Domestic Sim, They did not use the term unlock yet a lock symbol appears in the APN settings next to the Carriers APN(Verizon, T-Mobile)when the Sim card is in. Sprint pretended to be helpful. One support agent even gave me the msid and false ##12345# code saying to use the msid then to unlock, how nice. Another Rep discovered My phone has no Unlock MSL as it is not carrier locked. I purchased it, own it, never activated it on the Sprint Network therefore no MSL needed to unlock. I have an unlocked device. Locked "to" Sprint but not "by" Sprint. I have the right to provision data from any carrier of my choosing but how?
Not going to accept that it "can't" be done. It must be possible to trick or bypass the lock. Example: I took my Nexus 7 LTE to Verizon for a data card. Initially the rep told me it would not be possible. I now have LTE Verizon data.
My question here is can we trick the phone into accepting a Domestic Sim? It must be possible after reading so many threads and seeing the genius Dev going on here. It must be possible to use the device at least for Internet Data at least 3G. LTE should even be possible.
1. Force Roaming with Roam Control?
2. International Rom then the phone would view our Domestic(US) card as International?
3. Flash a Verizon HTC One Rom to the Sprint HTC One to trick the phone into thinking it is Verizon enabling the Verizon Sim to work?(using the sim from my unlocked tablet)
Anyone try this with Success?
This may be possible by provisioning through the sim by the new carrier (If they will do it) like with my Nexus 7 tablet. But I am curious to know if the above/or other options might work.

Samsung SM-G900A - from AT&T Unlock

Is it possible to unlock Samsung SM-G900A - from AT&T and use different sim card in another county
I have the same doubt. Any way?

I'm not sure, but maybe you can ask the AT&T customer care to give you the unlock code as well as the method to do it.
That's what I tried for my S2 and S3. I had them under contract. And if you buy it without contract, shouldn't it be unlocked already? Just curious!
I'll ask about the unlock process to AT&T tomorrow and let you know if the same trick works or not
Unless I'm not mistaken, you are not talking about rooting the device already, are you!
If you ever want to modify your phone, I recommend returning during your 14 day trial period. Otherwise, you will be stuck with a worthless piece of junk. Although nobody has verified this yet, the SM-G900T (tmobile) appears to support the same bands but I need someone to test with a ATT SIM
I want to root the phone because it may be blacklisted by at&t
I unlocked mine whit Swift Unlock.
The T-Mobile version (SM-G900T) supports all of the frequencies of AT&T, plus WCDMA 1700 MHz. Additionally, it's the only variant with an unlocked bootloader. I know people using it on AT&T.

That question makes no sense. By "bootloader unlocked", I mean that the T-Mobile version is the only variant that lets you flash anything without stopping you (e.g. custom ROM, custom recovery, custom kernel). Depending on what you flash, you will trip Knox though.

Blacklisting means the phone is lost, stolen or was not paid for completely. That means you can't use it on AT&T, and on any carriers that enforce a blacklist (most do in the US). It has nothing to do with custom ROMs or root.

I think what he is trying to say is, in the case I have a blacklisted non-unlocked SM G900A, is there a way possible to use this phone with another SIM under a non US based carrier in a different country. Also what he is wondering is maybe this is possible through rooting? if not is there any way that this can be done if yes please help... Thank you for all the feedback!
I don't think there's a way to do it through root. AT&T won't help you because it's blacklisted. You would need an eBay unlock service or something along those lines.

I think MobileTechVideos.com is the final solution.
They are an affordable service with great solutions to mostly everything.
Press the thanks button if this helped you :good:
no......and there is not a service that can "repair" the IMEI either......I "repair" IMEI quite a bit with a JTAG and the software will not work until there is a root available. You can however sell it in another country and it won't matter that it is blacklisted in the US. Unlocking the phone or rooting it won't do you any good in the US anyway since all companies have a joined blacklist now. If it's bad on one it's bad on all.
I unlocked my phone with this http://www.getunlocked.com/ page and it worked, Thanks for atantion

[Q] Found damaged N910T - Unlock, Root for Rom and Modem for ATT? [w/Pics]

My nephew said he found the phone on the road underneath an overpass. Screen digitizer looks damaged, no battery, no battery back cover and all banged up (see pics). He gave it to me to either fix or trash. I would like to get the phone looking new, working and give it back to my nephew running on AT&T's network.
Questions:
1. All the parts I need are compatible with most Note 4's correct? Will these work here and here?
2. Being a T-Mo device, the bootloader should be unlocked correct?
3. If the device is locked (not purchased by cash) can the unlock code be unnecessary by rooting? If not, what are my options since I did not purchase this device?
4. AT&T Roms are not compatible on T-Mo devices running on AT&T network correct? So will T-Mo Rom's work on N910T running on AT&T network?
5. Can I Root, flash Rom and modem?
Greatly appreciate your input, thanks.
Tmobile phone will work fine on AT&T. No need to flash anything special just pic a ROM and set up am APN.

I just purchased the T-Mobile variant and I am going to unlock it via http://www.cellunlocker.net. When checking out at cellunlocker.net they displayed a message:
"Please be advised in order to unlock your Samsung Note 4, you MUST activate the phone with the original carrier or SIM issued within your designated location. This must occur before you attempt to unlock and activate the phone with a foreign sim card. The Note 4 has a region lock feature seperate to sim unlocking and if unlocked before activating to its original carrier or continent the phone will be region-locked and must be unlocked directly from Samsung. For more information, please refer to the warning sticker found on the packaging that your phone came in."
Do I just need to get a T-Mobile sim and activate it once? Then boot it up with my ATT sim and enter in the unlock code? Or can I disregard this message?

1) not sure... most of the main parts should be the same.. i.e screen. There may be slight variations with many parts.. such as charging ports.
2)Bootloader is unlocked to my knowledge however Im not certain.
3) Rooting and unlocking are 2 seperate things. The phone will be carrier locked. I have a tmobile Note 4 phone that I run on AT&T. I paid to unlock it on simunlocker. Ive never rooted this phone yet
4)False to my knowledge. There should be no issue at all here
5)YOU cant change the modem to a modem from a different carrier. and there is absolutely no reason to do so. YOu should be able to flash an ATT rom on it if you'd like.
Unfortunately... It is true what others have said. If the phone was not paid for in full by the OG owner( on Tmobiles plan where you pay for the phone month to month)... then it will most likely be black listed at some point. SO you might be able to activate it but 4 months down the road it could suddenly stop working.

If it's blacklisted, nothing short of changing the IMEI # with a JTAG device can save it.
Considering it's physical condition, trash it. I would.

After $200 in parts that I received yesterday, she looks beautiful now . I much rather work on it until its fully operational instead of trashing it.
None the less, still blacklisted and unable to access engineering mode. Any pointers?
Update: Running rooted 5.0.1 with TWRP recovery and have successfully unlocked via imei-unlocker.com. Made a call to a business number, worked fine.
Leads be to believe down the road a few months service may be cut off due to blacklist? I would still like to explore other alternatives to avoid service being possible cut off...

Empty Data Triangle

Help!
I have a Nexus 6 that my son bought off of Swappa, and it worked fine for about six weeks. It has an AT&T sim card in it. One day he looks down at his phone, and has no data connection. The data indicator in the status bar just shows an empty triangle. He was running Chroma 6.01 at the time.
Things I've tried and the results: (I have tried fixing APN settings along each step of the way, the phone won't pull them in automatically. I've also tried locking it down to 2g/3g/LTE only)
1. Wiped and reinstalled Chroma - no change
2. Completely wiped and factory reset using Wug's - no change
3. Took to AT&T, had sim card replaced. New sim card works fine in another phone, but no change on Nexus.
4. Completely wiped, updated radio, and installed PureNexus - still empty triangle, but got a couple emergency broadcasts...very odd, tells me it has some kind of connection.
5. Tried all versions available for radio, tried rolling back to factory lollipop using Wug's, no go.
6. Wiped and install OctoOS - no change
7. Had sim card replaced one more time for good measure - no change
8. Took Verizon sim card and installed, now it has bars in the triangle, APN is automatically located, but no actual data...I'm guessing because the phone isn't actually activated for the Verizon account?
Edit: 9: I did check the IMEI through both Swappa and AT&T, and it came up clean both places.
Edit: 10: I did factory reset using Wug's to 5.1.1, 5.01, and 7. Full data wipes each time, including SD card.
Observations: The phone is reading the sim card, at least partially. It pulls the phone number from the sim card properly, shows the proper carrier, and almost works with Verizon (well, different results from AT&T anyway.) That to me indicates that it might not be hardware related, but I don't know what else it could be after doing everything I've done.
I'm hoping somebody here may have some other suggestions to try?
When I read your trials ... Did you try the official stock rom?
The N6 sounds like it's blocked on AT&T's network. Follow @NLBeev's advice first. If that doesn't work, I'd double-check the IMEI using Swappa's tool. The original owner might have had the thing financed and stopped making payments once he got his money.
I did actually, sorry, I should have included it in my original post. I'll modify to include it. I actually tried 5.1.1, 6.01, and 7.
Excellent suggestion, and I did actually try that. I forgot I did that, thank you for reminding me. I'll add that to my original post. I checked the IMEI both in Swappa and through AT&T, and it came up clean both places. Is it possible they could have blocked it a different way, not using the IMEI?
Granted I don't have even a sliver of the technical knowledge of the other members who commented, but, reading through your post and the thread...
It seems to me that the Nexus 6 might still be Carrier Locked to Verizon...

Which is possible even if the phone has payed off and has both a clean IMEI and clean ESN.

Very good thought, and I will look into it. I suspect it's most likely not the case though, since it worked on AT&T for about six weeks prior to it failing. The seller sold it as an unlocked phone, previously used on the AT&T network, but you know how that goes. Can't take anything on faith when it comes to used equipment :/

Typically Verizon phones are unlocked. I bought the N6 off eBay and the seller had Verizon at the time and it was a Verizon branded 6. I did not unlock it and used it on ATT/Cricket for 6 months before coming to Verizon.....
Have you checked to see if you have an IMEI number under settings? Maybe your EFS partition got screwed up.
By law (FCC) verizon LTE capable phones are sold unlocked, don't think it's a carrier lock issue
Have you verified with att (or who the use for insurance claims) that phone wasn't reported stolen after you may have bought it? I know a guy who bought a HTC 10 on Craigslist and it worked great for 3 weeks then was killed. When it was reported lost/stolen.

I did verify with AT&T that there was no report of it being stolen. The IMEI does show up in settings, as does the phone number. It shows "Carrier Unknown" in the carrier field though, but only when on AT&T. When I try Verizon, it actually reads Verizon as the carrier.
When I boot into the bootloader, it shows Device Unlocked, Status Code 3, so I think it's unlocked properly.
Is it possible, as chapelfreak suggests, that the EFS partition is corrupt? If so, is there a method to fix it?

Darn. So if there's no EFS backup, chances are this thing is now just a very small WiFi tablet? I didn't make a backup of EFS, didn't even bother to make any backup at all, just flashed Chroma and let it run for a month and half before the deathstroke happened.

I've read a few threads where the EFS got corrupted and the phone had to be returned, but that was several years ago so personally I have a EFS backup via TWRP on a OTG stick, but I've never had to use it. I know it's an option to back up in the nandroids for TWRP but usually that is not one of the boxes checked.
I agree with you though it is hard buying pre-owned items. Personally, I have learned from past purchases to stay away from anything electronic that has been pre-owned due to the unknown nature and it can be a hit or miss.

Nexus 6: As in 6 hours of trying but still no service?

I recently tried activating a Nexus 6 from AT&T to one of my existing Sprint lines. After Sim card switches, BYOD to SIMGLW446C and lots of support from a knowledgeable in-store tech it was determined that my phone was confirmed "activated" but it would not connect to the network.
The tech discovered the phone did not have a MIN nor did it list my phone number in the phone settings. They could not determine where the error was stemming from but told me the IMEI and ICCID were accurate and we confirmed the phone unlocked through ATT. (Unlocked two days prior to latest attempt at activating)
Nobody seems to know what is keeping this phone from functioning properly. Any input is greatly appreciated as I would love to have it in service. I have it listed for sale as AT&T but am starting to feel skeptical if there is just something wrong with it and shouldn't be selling it off for someone else to be disappointed.
Thanks for reading

Ok... I'm sure you made sure the IMEI that is printed somewhere... is not blacklisted...
Go grab the factory images and flash the newest radio from it using fastboot... See if that works...
If not... Flash the whole thing... Image at a time and see if that fixes it...

There is this:
Thanks for the input. I flashed a new factory image and it authenticated to Sprint's network just fine. It still wouldn't let me switch and activate online but no other issues aside from that.
