Hi i have a nexus 5 (d 821) and i'm trying to get it work again. It has no signal with a valid sim card. i am in europe.
I tried cyanogenmod ( it shows usa, japan automatic ) but no signal.
i tried lineage the same thing.
I restore it in 6.0.1 google img ( it shows only usa band ) but no signal.
i restore in 4.4 ( it shows only usa band)but no signal.
Is this problem software or hardware?? is there any rom that can make my phone work again?
I searched through the forum and cannot find any clear solution for nexus 5
thank u
Was the phone ever dropped or dismantled and put back together?
It finds no networks at all?
Sim card works in another phone?
Tried other sim cards in the Nexus?
If this is a 2nd hand phone device and a problem with other sim cards too, I'd check if the IMEI has been blacklisted by a previous owner?
it has some falls , but i dont think this is the problem.
at *#4636 menu it shows only usa band (original nexus rom) and auto us japan band in lineage rom.
I think that the problem is in software with the radio img, or else with antenna or motherboad as hardware.
i need the opinion of an expert to deal the software part,
the sim cards works on other phones...
Is the model number d820 on the fastboot screen?

I bought my mom a Moto G. The problem is, that once the phone gets out of signal, it won't connect any more the the service provider until I reboot the phone. I tried it with 4.3 and with 4.4, but it didn't changed anything.
Should I try to flash a different RADIO?
I'm from Europe and I use a German version of the phone.
did you solve that? i'm with the same problem.

d820 is for the north american market, but it should still connect to phone calls, just not lte http://www.phonearena.com/news/Differences-between-the-two-Nexus-5-models-D820-and-D821_id48985
So sorry I meant D821
have you tried to use a different sim card? someone elses sim card..
My nexus Sim is Vodafone and I have a tablet that supports calling with Etisalate Sim, I switched the Sims and the Vodafone one works perfectly on the tablet but the Etisalate don't work on the mobile and when I returned them back the Vodafone don't work again and the Etisalate works again so the problem is with the phone
I tried re flashing Paranoid Android but the same problem
Try flashing stock. If it's the same, it's hardware. Sim card, device or something. Or its carrier related issue.
Sounds like the radio is set to LTE only mode.
Dial *#*#4636#*#* and check your network configuration

Lol I found this on the internet and did it and it worked before you even said but I'll hit the thanks button anyway ??
Hi folks
My Nexus 5 - unlocked with factory 6.01 MMB29V - has no signal "No Service" displayed. I think it is because I messed up when entering the Phone Info menu (*#*#4636#*#*) and selecting "USA Band" which is now the only option available. I'm on Virgin UK but get the same issue using an 02 SIM card too.
Could anyone offer a solution to getting back the European Band option, if that is what is needed, please?
- many thanks.
The phone is a d820 or d821?
Hi its a D821, bought from Carphone Warehouse in the UK.
Hmm, I didn't think it was possible to enable North American bands on the d821 as the USA and Canada have the d820.
Have you tried reflashing the radio from a stock rom or an entire stock rom?
Thanks for reply.. I flashed ROM from Google's factory images (hammerhead-mmb29v-factory-62a68ee9.tgz) but the option still remains as only "USA BAND".
There seems to have been a solution using a temporary ROM for the Nexus 6P & 5X to bring back the full options:
http://forum.xda-developers.com/nexus-6p/help/recovering-usa-band-to-auto-mode-4636-t3271347#
But I haven't found any solution for the 5
- regards
Maybe a solution
I got contact to bitdomo and got some infos:
!!! Both advices are from bitdomo, nothing comes from me. I deserve no "Thanks" if this works. !!!
1.) Flash Lineage OS an hammerhead. LOS had the "changing-baseband"-feature included. (Yes, feature is included, but did not work for me -> maybe got hardware-issue)
2.) Try:
"Your device probably has a hardware fault or the efs got corrupted by an imei change. The originial imei is printed on the main logic board somewhere. If that does not matches the current imei when you dial *#06# then the phone you currently have is stolen or someone tried an efs repair before. Also Linage Os do the same thing what I did for nexus 5x 6 6p and pixel. Back up your current efs Copy the backup to your pc Try this https://www.youtube.com/watch?v=y3lGxQkNaMg Download link in description. Everything you need to rebuild a working efs is inside the rar file. If everything stays the same then you have a hardware problem."
(Everything works, but in the end nothing changed -> I got a hardware issue)
Hi I just got a nexus 5 as a hand down and I can't use 3g or 4g I have manually changed it to 2g with *#*#4636#*#* and it works fine on 2g. And where it says select band it's usa??? Has my phone flashed with a usa ROM and will it be fixed if a flashed a UK based ROM for it the bootloader is all ready unlocked but got no PC to fastboot or flash twrp it also says on build prop that the locale is US when I can view it in ex file explorer I'm not root on 601 stock ROM
Anyone at all

D821 32gb variety
Very strange because the d821 is the non-USA model and should work in the UK.
It says d821 in the ROM or in fastboot? Fastboot mode will show the actual model #.

Deffos a d821 and when you go to select band it says usa?? Do you think it's been manually flashed USA ROM via fastboot as bootloader was all ready unlocked when I got it
As you can see in screen shots it does detect my sim but not 3g or 4g signal but 2g signal works fine
I've checked antenna cables and there fine so it definitely must be a software issue
Is it running a stock ROM? Does it say d821 in fastboot?
Is the imei properly displayed? Could the imei be blacklisted or blocked by the carrier?

Yes it's on stock ROM with stock recovery it is a d821 in fastboot the IMEI is displayed in settings and haven't checked blacklist any free services but if it was blacklisted 2g would not work as I can still text ring and edge data works
Just checked the Imei and device is not blacklist
Everything certainly appears to be in order.
Does the phone work properly with a different sim? The sim works properly in another phone?

I would if I had a PC or a laptop but I'll get round it somehow thanks for the help
Does the screenshot mean mine is a USA variety and it won't detect the uk bands hence why It states USA bands in *#*#4636#*#*
The FCC ID indicates the phone is a d821. The FCC ID for the Canada/USA version is ZNFD820.
Well I tried to flash the factory image again and the problem is still there I have even installed twrp and pure nexus and it still doesn't pick up 3g or 4g
I was curious as a colleuge of mine recently purchased the OP8 5G from T-Mobile rather than directly from OnePlus. The sim tray only supports one SIM, and I am assuming that as it has been done historically on prior OP devices, the T-Mobile OP software only supports one sim card. I am unsure as to whether the T-Mobile variant has hardware to support two sims or not, but I think it may only a software issue. Would rooting and flashing to get onto the Global firmware enable dual-sim support for a OP8 5G T-Mobile variant?
Thank you,
I'd assume so. I'm planning on trying this myself when my dual sim slot comes in from Shenzhen.

What is the dual sim's use case for you? International travel or work/personal use?
I think in Asian countries, people often get 1 cheap SIM for cheap voice plan and another SIM for cheap data plan.

In my colleague's case, for work and personal use. I personally have my OP7 Pro as my work phone, and it is the unlocked non-carrier variant, so the dual sim support is there. However, for my use, too, I would like to have the capability available on my T-Mobile OP8 5G just as my colleague. I had him order a dual-sim tray from eBay, and from a US seller to get the item faster. If it works for him, I'll likely order the dual sim tray.
i dont think the global or eu roms support dual sim. there was a disclaimer under the network & sim settings untill ob1. not sure if ob1 supports dual sim yet
Dual sim works, however, i cant get my Verizon sim to work with t-mobile. I get the CDMA-less notification, i read that you can get it to work, you just got to call verizon to register your imei with them so dual sim can work. This is running open beta, stable 10.5.12 wouldnt see my second sim.
I havent called them because my verizon sim is through work.

And, this is on a T-Mobile OP8 5G? If so, I wonder if my colleague would have any issues running two T-Mobile SIMs on a global ROM? (I suspect the T-Mobile software doesn't even recognize a second SIM).

Yes, this is on my t-mobile OP8. I converted to global because I prefer global. I haven't tried two t mobile sim cards, and I haven't tried using t mobiles firmware.

So, after receiving the dual sim tray, and inserting two SIM's on T-Mobile's software--it does not even recognize the second SIM. What particular guide did you use to port over to the global firmware? Thanks!
I would also be really interested in knowing how to get the second SIM to read on the T-Mobile IN2017 variant of this phone. I've been tearing my hair out trying to get this to work, now that I've seen that the international models running Android 11 OB2 seem to have functional dual SIM. Personally, I kind of gave up on getting Android 10 to do dual SIM- even with the European ROM (which I'm fairly certain is the only way dual SIM on this device was ever officially supported by OnePlus), I haven't gotten it, but I think I'm annoyingly close. T-Mobile MSM to Global 10.5.12 to Android 11 DP2 will get you non-functional dual SIM- the device will see both SIM cards, and will properly identify them and their phone numbers, but the second SIM won't connect to voice or data, no matter what I do. If I upgrade the device from DP2 to OB2, the dual SIM UI stays (if I go directly from Global to OB2, it doesn't show), but the second SIM slot is still non-functional- no service for voice or data on the second SIM.
For anyone who has gotten a T-Mobile OP8 to properly read two SIM cards, I'd really like to know how- through my hours of messing around with this thing, it always seems like one step forward and two steps back. Hopefully the final release of Android 11 clears this up.
(My two SIMs are from T-Mobile and AT&T, respectively. Unfortunately, I don't think two T-Mobile SIMs has a chance of ever working with this setup on any firmware- "SIM 1" and "SIM 2" share an IMEI. While that's probably okay for SIMs from different carriers, that's not going to fly on the same carrier- it will look like a cloned IMEI to the network, and probably get shut down fairly quickly.)
Has anyone managed to make it work the Oneplus 8 (pro) unlocked USA version with 2 sims at the same time ? Thank you
It's working on mine with second simbtray however there is no service with both inserted. BecUzebitvhas the same IMEI as slot 1

1. First of all unlock bootloader and u also have permanent sim unlock from t-mobile.
2.After unlocking your phone will restart, setup your oneplus 8 and enable developer mode and in developer mode enable "usb debugging" .
Note: You must have working adb/fastboot drivers.
3. now restart your phone to bootloader.
4. Download any android 10 fastboot Rom from xda developer.
"I have tested this : https://sourceforge.net/projects/fastbootroms/files/OnePlus 8/10.5.9-EUROPE-OnePlus8Oxygen_15.E.18_OTA_018_all_2007160043_913306-FASTBOOT.zip/download
4.1. For flashing this rom your phone has to be in fastboot mode.
5. After downloading extract the rom and open extracted folder and double click "flah_all.bat
5.1.connect your phone to computer in fastboot mode and enter "Y"
wait for 5 to 7 minutes, in this process your oneplus will restart to recovery mode but never unplug the cable or use your phone during installation.
Note: i have tested dual sim with dual sim tray.
