[Q] Radio/Modem not working at all. - Nexus 4 Q&A, Help & Troubleshooting

Hey, I normally wouldnt make a help thread. But Im at a total loss of ideas on how to fix this. My Nexus 4 has been running on AOKP 4.3 nightlies for a week or so perfectly fine. Today out of the blue I lost signal all together, so I went through the normal steps of checking if everything is in order. I tried to go into my apn settings to check those, but I just got a force close upon opening my mobile networks settings. I tried using the *#*#INFO#*#* menu to check my phone settings in there, but that force closed as well.
So I flashed a clean ROM and tried to check my APN settings. I was able to get into the APN menu this time, but when I would try to save an APN and it would just exit the setup screen without saving an APN. When I try and change the setting to anything (for example, GSM, WCDMA, etc) in the *#*#INFO#*#* menu it instantly resets to "UNKNOWN" I have tried flashing multiple new radios, and new kernels and nothing has worked. I'm totally lost.
Any help would be enormously appreciated. All of my previous phones were CDMA phones so I cant really just swap my sim into an old phone to use.
EDIT: Problem was resolved. If you find this thread because you have a similar problem, download the factory image from Google's site and flash that. That fixed it for me.

I've tried flashing a few of the radios from that thread with the same result every time, unfortunately.

Currently what ROM you're using? If you're on nightlies you should be aware that it isn't stable. I suggest you restore your nand backup if you have one.

Im currently on an AOKP nightly. Im trying to flash back to stock but Im having trouble getting it to do that for some reason too. Its acting like its been flashed, but it always boots up into AOKP again. Trying my hand at another toolkit before I start attempting to do it manually.

Flashing back to a factory image fixed the issue. Thank you!

Don't forget to make a backup. By the way I just got my 4.3 with CM 10.2 working with franco kernel.

No Service after flashing ROM done Nandroid b/u still No Service

Well I flashed NexusSence 0.3 earlier today and love it,
The only thing is I get no service and obviously cant use the phone or data, I thought this was a problem with the ROM but after restoring to a Nandroid back up I still get no service. I have several back ups and none of them resolve the issue.
Can someone please advise as what I do next.If anything. I have searched but not found anything that makes feel confident in doing anything else without first asking.
I may be wrong but I'm pretty sure I need to flash the radio .img but the question is which one??
Thanks
***********************************************************
I'm in no way blaming NexusSence for this, it could and probably was something I did or didnt do.
the funny thing is I still have signel bars that apear to work and when i go to
>setings>wireless & networks>mobile networks>network operators.
I can scan and picks up my local mobile network carriers,
When I choose O2 who ive got my contract with it says:
Registering on O2 Network
then:
Unable to connect to this network at this time. Please try later
HELP
Have you tried...
Have you tried going back completely stock and unrooting. Try using one of the official rom images in the dev section
Exactly the same issues.
I was on NSCollab before this, restored and facing the exact same issue as the OP.
Right now im flashing NSCollab again, will restore again if the fresh installation fixes the issue.
btw. which version of CWM are you using?
Something similar happened to me with an i9000. I solved it by flashing back to stock AND doing a factory reset on the stock ROM.
Also verify that your IMEI hasn't been erased.

^ Nope the addresses are completely different.
iv'e had this happen on 2 occasions, first was on CM7 nightly 85, other was on Zuluzulu rom, i thought it had something to do with CM7, reverted to a former back up i made, wich was fine, and now on and AOSP rom, also without a problem!
really like to know what causes this problem, as i like CM7 roms the most!

Problems with 3g and ROMs

So when I first rooted my phone I put Fresh on there. I installed the ROM and the 2 radio files. I then got the 3d and gave the evo to my gf, but fresh was very slow for me so I installed the CM7 ROM.
CM7 was very buggy for her, especially since she was new to Android I decided Sprint Lover's ROM on there and flashed a newer update on it since.
The problem is that she has been having problems with 3g. She has so many problems and errors with 3g data. It shows that she has 3g, but she gets errors when she tries to access the internet.
My question is, how can I get it back to stock or a nice rooted stock rom to try and fix this problem? Do I just flash a stock rom? I'm guessing the fresh radio's might be messing something up. If there is a simple solution to this without having to do a full erase I'm sure she prefers that, being that we've fully erased her phone like 4 times already, lol.
Thanks guys.
Get the Sprint Lovers all-in-one package from here: http://forum.xda-developers.com/showthread.php?t=830153
It's flashed through hboot (it's a PC36IMG.zip) and will flash not just the rom but also the radios. This will wipe everything.
Alternately you can go here http://forum.xda-developers.com/showthread.php?t=715485 and get just the latest radios and flash those. Flashing this will not wipe everything.
If the problem is with the radios then that should fix it. If it doesn't, then it's likely that the issue lies somewhere else.
thanks, just installed the new radio's. Will see how it works.
I would definitely just get the app mybackup root and back everything up apps/data , sms etc.. Then just restore everything after you flash a new ROM.
Then just do a fresh install of what ever ROM you want then test out different radios till you find the best ones that work for you I'm on old radios because the newer ones didn't work great for me not all evos work the same .
I hope that helps you out some.
Sent from my PC36100 using XDA App
I got simalar problem like u.
I installed new radios, try different roms like MIUI, CM6, CM7, Miks, Minn, OMJ's, etc...... finally I go back to stock rom but still got the same problem.
I almost crazyy
the phone never got 3G signal, it only works 1G no matter what I did.
I've reserched couple days but looks like nobody got my problem.
now I fixed my problem btw... well I'm not sure this thing works to u or not
anyway try it if u still got 3G problem.
*I don't even remember where this posted originally,,, somewhere this forum or not,,
huge thanks to original author btw
download 'MSL reader' at market n get the numbers. it's 6 digits.
go to your phone and type ##3282#
tap 'edit mode'
type that 6 digits from MSL reader
tap 'data profile'
open menu n tap 'restore'
then the phone will be reboot.
when booting is done, your phone will start resistering to network.
after that, if something popup n ask update (mayb PRL update), 'cancel' it.
mine works perfectly now.
hope this work to u.
ok thanks, i'll try it out. I do get "3g" at the top though, but always get an error while trying to retrieve data.
Also, what files in the SD card are necessary? Is there a list? I think there are so many junk files in there taking up space, I don't know whats necessary and whats not.
Please help slow EVO 4G after flashing Sprint Lovers All In One
Obvious Noob here.
having issues with my Evo 4G after flashing Sprint Lovers All in one
phone seemed very fast immediatly after flashing SL but since then has become just overall slow.
in fact, i'm downloading an update to ROM Manager right now (a 2.27MB file) and it's taken literally 20 minutes to get to 75%. it's painful!
when i go in to manage applications...says "computing" on space, data and cache etc.
before i flashed SL all in one i ran factory reset 3x in a row prior to flashing - i did NOT re-format my SD card but had it removed (after unmounting).
Should i try to wipe and re-flash or just go to CM7? Are there any things i can try before re-flashing or moving to another rom? Please help..
thank you OB1B

[Q] Why does my Wifi & Bluetooth not working even with stock rom?

Hey guys,
I have a Galaxy S4 (i9500). I installed Omega ROM v22 on it and everything went smoothly, Wifi & BT working perfectly.
After a few hours of using the device (nothing special at all, texts and stuff like that) - I noticed my wifi isn't working and by not working I mean that I click the wi-fi button and it changes from gray to the mid-state between gray to green for around 20 seconds before it goes back to green ago.
If I open the menu to see my networks it just says "Enabling" without any networks there.
I had to drive somewhere so I went to my car and tried to enable Bluetooth, and same thing happens there - Bluetooth will not turn on and will stay stuck on mid-state between gray and green for a while and go back to green.
I flashed omega rom v22 again and the problem was gone, or so I thought. I went back to the car for another drive and realized the bluetooth issue is back - and when I got home I realized the wifi issue is back as well.
I figured I need to reset everything so I tried the following:
Full wipe (including dalvik and even including "internal SD card") and then flashing stock rom (from the official website, stock rom of my country).
The issue was back after a few hours. I do not have BT or Wifi access. Yesterday Wifi suddenly started working for a few hours but then it stopped working again.
I really need help! I have no idea what to do with this issue!
Well rule number one when you have problems after flashing without wipe.
1. perform a full wipe and see if the problem persists.

Tried that, no luck.
What else would you try?
In some places when people had problems with Wi-Fi they said to flash a different kernel but I don't see why I would have this specific issue with Omega Rom and why the default kernel with it wont work well?
Maybe this could be a root issue? My root works fine but I have this weird gut feeling like this is some permissions thing that's going on.
I'm trying to think why it would work right after the wipe but then stop working shortly after.
Another symptom: It randomly started working for a few minutes and then stopped again (around three hours ago).
Any idea what's going on?
Well, if you fully wiped and didn't restore any apps and settings then it can be two other things.
Or it's a bug in the rom or a hardware failure in your phone.
I would suggest trying a different rom first. Do not restore anything, not even your google account.
wi-fi fix?
Do you actually have an i9505? or is it a canadian or att version? if its the latter sometimes the devs offer some wifi-fixes, also try a different kernel. otherwise it could be that your radio/modem are not compatible with the version of the ROM you are flashing.
Tried arrow ROM and this issue doesn't seem to happen in this rom. Hope it stays like that...

Sadly, it did happen with this rom, after just a few hours.
I'm now using stock rom and still suffering from the issue.
Does anyone have ANY idea what I can do to fix this?

[Q] No data on CM12 on my LS980

Over the last several days, I've noticed I don't have any data connectivity on my LS980, running CM12. I'm on the ZV8 radio.
Things worked fine a few days ago--I'm not really sure when it stopped working, maybe when I installed the most recent nightly (150505)? I've tried toggling roaming on and off, wiping things, reinstalling, rolling back to both CM11 and the nightly where I knew it worked (150405), all without any luck.
I can make calls and text, and wifi works just fine, but I've got no data service at all.
Any suggestions on how to troubleshoot? I'm happy to do some digging, but I don't really know where to start!
Did you figure this out
Im having this issue also
Yeah, it ended up being that some of my radio settings were jacked. If I remember right, I switched Preferred Network type from CDMA/EvDo/GSM/WCDMA to CDMA + LTE/EvDo.
And then it started working.

I guess my settings got messed up also during my latest nandroid backup.
I had another working backup......So I just flashed the old working backup, then flashed the Data only from the non working backup restore.

Phone says dialing but never connects. Incoming calls don't ring either

Phone seemed to stop working yesterday. Last time I used it was via Bluetooth paired with my wife's car.
I get signal and can text, just not send/receive calls.
I was on dirty unicorns official and had not messed with anything in several weeks.
I just updated radio and vendor and installed latest weekly of dirty unicorns.
Anybody go through this before? Any advice?
Thanks.

What does your prl version say under your IMEI settings? I had this exact problem when I flashed the latest PN build. I tried everything to fix it. Flashing my EFS backup worked for a while but sometimes on a reboot I had the same issue again. Flashing EFS would fix it again but it was temporary. The permanent fix for me was a clean flash of Chroma ROM. Just curious but what carrier are you on? It seems like this issue has been affecting CDMA carriers like Verizon more than others.

When I had this problem the prl version in my screenshot said unknown as well as the MIN number. If you problem started after flashing an update I'll guarantee its software and not hardware. If you have an EFS backup I would try and flash that first if not I would do a backup in TWRP and then clean flash Chroma. If it doesn't work you can always just flash your backup and be back to where you are now.

I'm sure you have already checked the APN settings but it would be a good idea to make sure they were not changed when you updated. Are you in a good LTE area? A lot of people with this issue could make and receive calls over LTE but when they didn't have it they couldn't even though they had service. That's why I think it affected CDMA carriers more. LTE goes over GSM and 3g goes over CDMA. Does your phone number show up under SIm info?

The EFS doesn't change. The original backup you have is all you need as long as you have a backup of just the EFS partition and nothing else with it. It might not fix your issue but it won't hurt anything. I tried Chroma after reading it fixed a lot of others problems with the same issue and that worked for me also. I'm still running it but others have said they were able to go back to their preferred ROM after flashing it and all was good.

As long as you clean flash their shouldn't be any issues. Just go to advance wipe and select system, data, cache and dalvic. Just make sure you don't check internal storage. Then flash chroma and the recommended gapps and you should be good to go. Make a backup first and you can always just flash back to the point where you are now if it doesn't work.

I don't have an EFS backup on my google drive (like I thought I did). I think I have the backup in the office, but not available now.
No joy on the Chroma -- still no PRL data, no phone sound on dialing, no receiving calls
At this point, I figure it's hardware related

Have you changed any settings in the test menu? Another option would be to swap sim cards out with another phone to see if yours works in theirs and vice versa. As a last resort before you RMA you should wipe everything and flash the stock images and start fresh. Even if that doesn't fix it I think you would have an easier time with the RMA process being completely stock and relocking your bootloader.

So, uh, I forgot to mention a critical piece of data: I live in Georgia, but this occurred at one of the South Carolina beaches, over 300 miles away.
I had full LTE, but noticed the phone said Not Roaming (or roaming: false).
As soon as we got home today, boom -- could make and receive calls again.
So, I think I can close this thread and open a new thread on how to get roaming to stick.
Thanks for all your help! :good:
