LTE not detected-Sprint - Nexus 5 Q&A, Help & Troubleshooting

Hello. LTE is not detected on my Nexus 5 (Sprint).
I've been thinking on downloading a factory image ( https://developers.google.com/android/images#hammerhead). Will this image override my modem/baseband drivers?
My ex used this phone before. I would not be surprised if she did something weird to the phone.
Any other ideas? I already tried *#*#3282#*#* and *#*#4636#*#* to select only LTE, then LTE/CDMA then I have updated the PRL..
Thanks

Nexus 5 cellular network issue on 2G only

Hello everyone,
One month ago my device had a problem of rebooting again and again and again. . . , I give my mobile phone to service center, they said you need to change motherboard to solve rebooting problem.
But I didn't change mother board, my rebooting problem solved when I pressed power button hardly.
In service center they disassembled my phone to checkup. after then when I got my mobile phone back my new problem started.
My problem is with cellular network, my build number is MMB29K my radio is radio-hammerhead-m8974a-2.0.50.2.28 my device bootloader is unlocked. my bootloader is bootloader-hammerhead-hhz12k
My device is unable to find cellular network when I set preferred network type to 2G, my device can only find network on LTE and 3G.
I tried this different radios too radio-hammerhead-m8974a-1.0.25.0.23.img, radio-hammerhead-m8974a-2.0.50.2.26.img, radio-hammerhead-m8974a-2.0.50.2.27.img But nothing works,
This is a hardware problem?
Anyone have idea how to fix it?
Please help!!!
Sorry for my bad English.
Does your carrier support 2g? In Canada, there is only 1 carrier that has 2g.

Yes my carrier supports 2G I live in India
Hmm, possible loose connections inside the phone?
I have the same problem, im from indonesia and im using D821, after upgrade to marshmallow, my phone only have 2g, no 3g/4g. i have solved the problem.
- first i downgrade my n5 to 4.4.4
- flash modem using recovery NEXUS5_KRT16M_RADIO.zip
- Reboot your phone
- flash again modem using recovery NEXUS5_KTU84M_RADIO.zip
- reboot your phone
- go to setting, more - mobile network - APN
- reset all APN on the list than create new apn of you mobile carrier.
- and the problem solved.
nb: bootloader must unlocked
( i dont know why should flashing the modem twice, i have try only flashed NEXUS5_KTU84M_RADIO.zip from the stock of 4.4.4 but the problem still on my phone)
sorry for my bad english.

Help! Phone switched to CDMA

Dear all,
I have a global version of galaxy s6 (g920f) originally on stock rom 6.0.1 and rooted. Last night i was trying to change my network preference settings from lte/gsm to lte/gsm/cdma through *#*#4636#*#*.
I did that because my phone either stays at 4g or 2g only without switching to 3g. However, after doing that, my phone suddenly switched itself permanently to cdma mode only, which is not usable in my country (malaysia).
I've done factory reset, reflashing stock firmware to stock though odin but the phone stays the same and become unusable. I've tried searching for other solution in the forum but i cant seem to find one.
Kindly advise,
Thank you very much.

Note 5 SM-920P bought in China

I bought a Note 5 which worked fine with China Unicom, the phone was 5.1.1 so I decided to manually update the phone to mm. After the update the phone can make calls, but it can't pick up data signal. I've tried everything from flashing the modem back to 5.1.1 (which was the one that worked, originally) but no dice. I was wondering if anyone had a solution to this. The phone isn't rooted and its constantly trying to activate its voice and data, even though the voice all ready works.
Enter the APN settings manually for your network. The same happened to me on my Unlocked N920P. I entered the APN (Airtel India) and deleted all the others. On upgrading, it will automatically pick up the Sprint APNs. So add a new APN and enter your setting for your network manually.

It happened to me too. The first step was the APN. changed the APN manually on mine but still it seemed no data connection was active. On step two I discovered that even the data seems not active, in reality there was a data connection and everything was working, but the icon was not showing due to something missing in the Sprint's SystemUI data connection icons.
So, try to put your apn manually and try and check if there is a data connection, i.e. using the browser to navigate.

Open the notification panel - touch the "down arrow" symbol on the upper right corner to show all the icons and look there must be the data connection icon you're looking for.
As for the update: Updated myself to MM and everything works fine with the exception of 4G. This is not something caused by the update but because the LTE-4G bands the phone works are not compatible. Check yourself @ willmyphonework.net
Flash pure GSM kind of roms.
First go to official MM by ODIN, root it,
Via TWRP, flash Lamlazy ROM or aurora rom which is compatible rom without sprint stuff.
Try this rom http://bbs.gfan.com/android-8394771-1-1.html
Download link pan.baidu.com/s/1c2JZgje PW kr10
I didn't try yet. but it says N920p supported. If u are on sprint, am not sure how it works.. but GSM should work well.
That V7 of Lamlazy can be found here -- thread http://forum.xda-developers.com/show...&postcount=153

No LTE 4G option in "preferred network mode" D83820d

hello everyone
I upgraded from kitkat to the D83820d twn xx rom a long time ago, and noticed that I only have GSM, WCDMA, and GSM/WCDMA auto options under preferred network, but I didn't care at the time because I wasn't using this device for internet much. but things have changed.
I tried the hidden menu method where you select "Automatic" under WCDMA-Only Network Mode but it didn't work (preferred network mode options didn't change). Does it only work for specific roms? I also found the cust.prop method but I'm hesitated to try it cause I found complains of phones getting bricked.
which method should work on my rom?
The answer is already there on the forum: http://forum.xda-developers.com/showthread.php?t=3025868
See post #20 or #29 for solution. In my case i had to make a change in two cust.prop files in that directory. Now I have GSM/WCMDA/LTE as preffered in network mode menu.
