3G & 4G Not Working 😭 - Nexus 4 Q&A, Help & Troubleshooting

My network only connect to 2G (EDGE) only. I'm using Custom ROM "Chroma", Android "6.0.1 r10" and Kernel "CallMeAldy". Any solution ? ???

i think the problem is, you have not activated 3g on your sim. First activate 3g/4g on your network than get settings, enable package and than use. Also it might be problem with your network and make sure 3g/4g is available in your city.

Is the phone using the latest bootloader and radio?

How to check and can you give me a link.

Boot info fastboot mode and look at the bottom of the screen. The latest baseband is m9615a-cefwmazm-2.0.1701.07. The latest bootloader is makoz30f.

My baseband is m9615a-cefwmazm-2.0.1701.03.
My bootloader is makoz30d.
Please give a link of latest things sir...

I'm using latest custom ROM Chroma, Android version 6.0.1 r10.

[Q] Updated to MKF & Now Unable to Get Mobile Internet

I recently updated to the MKF update on my i9505 BTU. Prior to this my mobile internet was fine. Since the update I am unable to get any mobile internet. All settings are checked to ensure I should be, the APN hasn't been deleted and I've got no idea why this should have changed anything. I'm on the EE mobile network.
Any ideas?

The carrier is "CLARO" and the kind of band is UMTS or HSPA+

Did you configure the APN settings for your carrier? If not, you can find the menu in...
Settings > Wireless and Networks > More Settings > Mobile Networks > Access Point Names
I am on ATT, so I cannot verify if these work, but I did find these...

Thanks for reply! The problem isn't in the apn or internet conection... Is in all the carrier registration, that means can't call or send sms.
Sometimes the 4G symbol appears and I can navigate in internet but don't allow me to call.

APN settings is all I had. I have an ATT on ATT network, so I do not have too much experience configuring the phone on other carriers.
In the OP, you mentioned "This happens in all the iB4STiD new version of roms in every Kernels." Did it work on his older ROMs or another dev's ROM? If so, I'd suggest flashing one of those to see if it is still working.

PM him with ALL your details--
Did you wipe (not format) System/Data/Caches? I do it 3X
If you don't have lte, did you change your preferred data choice to hspa+/3g or whatever choice has no lte in it.
Pull and reinsert your sim--

Yes, yes and yes. I do all, but nothing change. I installed a old version of GE (37, 38, 38.1) doesn't work.
Now I'm trying with GE 30. First I trying SHOstock and seems work.
I got more information for you!
The problem started when I installed a KK 4.4.4 Rom, before this never happened anything and always a custom rom allowed me to call.
PD: ONLY with the stock rom (I337UCUAMDL_I337ATTAMDL_ATT) and a based 4.4.4 custom rom is installed it can use the phone for call. Not just the internet!
Anybody knows something about that???

You are on mdl firmware. It's android 4.2.2. You could try flashing a new modern. See rockrat's modems in the general forum

No, it'll just flash the modern. Nothing else will change. I'm not sure if it will help you though. It could, modems sometimes work better and other times not. It depends on where you are and what works better in that location. You can always flash back to the mdl modem, i.e. baseband

Best way to udpate PRL with CM 10.2.1

I am running an old CM 10.2.1 rom and need to update my phone's PRL. I may plan a trip to Canada and need to make sure my phone will work. Though my ROM is old, what is the procedure for updating PRL?
Make a backup of your custom ROM then flash a TW based ROM. Update your prl then restore your CM ROM.

Update,
Was in Canada over the weekend and found out this ROM doesn't work at all for international roaming. Signal on the phone was very poor and the phone couldn't access the web. I did update the PRL before leaving. I had to restore my phone back to stock in order to use. Anyone have any luck using a custom that works well international roaming?

PRLs won't do anything for international roaming unless your phone supports the bands those carriers use

Please do another screen of settings with system and baseband version.

I have been last week in hungary and T Mobile HU was working fine on my axon 7 G Version.
I would recommend two things:
Check if your SIM Card is working fine with your device, or go into a T Mobile store and set another test card in. Or find someone who has another sim card for you.
But as far as I understood you, with the chinese ROM you had a signal?
Check if you can see the available networks in your area. (Mobile providers settings)
Double check your APN settings.
My SIM card work well in my other phone so it must be within my axon 7. My axon 7 I can turn on off the airplane mode and it can see that the sim card is T-Mobile but can't call because it says that I have to turn off airplane mode.

You probably have no signal because you flashed another model's ROM through EDL. you have the wrong NHLOS.bin file.
You have to follow a guide to unlock the bootloader ON YOUR PHONE MODEL (A2017!) then you can fix it
Cant i solve it simply flashing the right rom ?
Do i need to unlock it?
If so can you help me where to go?

I don't really know if flashing the corresponding ROM will fix your phone, but I think it will. You might like MiFavor 5.0 anyways
I'll send you the EDL package link for an A2017 rom. flash it and if you have signal, update through OTA. No need to unlock
Right now i tried global edl rom.

You shouldn't have tried the G rom! You messed up the modem in the process. That's why I don't know if flashing the chinese ROM again will magically fox things. But it's worth trying
The ROM is this one. I think it is MiFavor 4.2.

I'm using a i9505 as a media device at home. As opposed to all my other devices this phone loses its connection often every few minutes and also often doenst reconnect itsself. Its super annoying. I cant stream nothing or make a internet call.

Your carrier stopping at HPK2 simply means they didn't bother putting any work into what to them is a minor update. HQK1 will work on your device without a problem.
Hey again, I flashed the latest STOCK I could find on my i9505. But with STOCK i even cant enable wifi. I already did a factory resst but it doenst help.

If you unpack the ROM package I believe you will find a .bin file for the wifi you can flash in Odin.
