Nexus 4 loses mobile signal when trying to connect to 3G. - Nexus 4 Q&A, Help & Troubleshooting

Basically what happens is the phone works fine while on WiFi but as soon as I disable WiFi or leave the area, when the phone tries to connect to 3g it loses signal completely. It shows the H+ briefly, then shows grey bars and then shows an empty triangle for about 3 seconds. I was running the 4.4 ROM released by paranoid android a few weeks ago with no issues until today when calls were constantly droppiing while I was out.
I've since tried updating the radio, tried two different 4.4 roms, flashed back to 4.3 rom 3.99 paranoid Android rc2 including the boot loader and radio provided in the xda thread. Still no luck. So my question is...is there a magic fix? Or will I need to replace the antenna? Im going to try get a new sim tomorrow and try that but I don't see why that would be the issue?
Thanks

Lately people are complaining about the signal issues..Pa has been the common factor in all.. I would suggest/recommend you to flash psx v2 + franco + radio + bootloader.. If you have already updated to radio n bootloader,good. Best combo.. no problems.

PSX version 2 is the KitKat ROM. It's in the Original Development.

darkstar09, are you having problems with restarting your phone? Because I'm having this mobile signal bug as well + a massive reboot problem. I allready downgraded to 4.3 but the problem was still there ..

DHD Wifi problem

Hello
I have been roaming around for like a year or so now without registering cause i didn't had any problems following stuffs from here. But now...i have like a huge problem with my Wifi and BT. Around 3 weeks ago i flashed the BeatMod ICS ROM and everything worked just fine...then one day my phone started freezing at lockscreen...like it would start up, but after pushing the power button to lock my phone it won't turn on anymore (except soft buttons)...Then i went back to stock 2.2, made S-OFF, then ENG-OFF and flashed a radio (i can't recall which one) cause i tought that was the problem...indeed that seemed to fix my lockscreen problem..but then once my phone stucked and i had to remove the battery so i could turn it off...it started to freeze at bootloader and at one point simply turned on...it seemed okay....everything worked...or at least that's what i thought until i got home and tried to turn WiFi on...it kept saying error...same with BT...i have no other problem with it except those 2...here is a logcat screenshot with what it says when trying to turn wifi on...any help is welcome
P.S: i love u guys xD xda rocks :]
Seems your radio is bad, either a bad flash or a bad radio. Did you check the MD5 before flashing it?
You might want to flash a different radio and see if it helps.
yeah i did check the md5 checksum, ummm i have no idea...i flashed another radio too but that didn't helped so i restored the phone using a 2.2 WWE stock rom from shipped roms or how it's that site called...hoping that everything will work fine, but it didn't , i might just try to flash a radio again and see if that helps. Thanks for your answer
You can check in the development part of the forum and get the latest radio
Put the .zip in the root of your SD, boot in recovery it should ask if yuo want to update
There you go, should solve your problem
i just tried that yesterday...same thing...and the errno i get from BT in logcat is 19 and the wifi driver thing persists...attachment below...
How do you have flashed the radio???
CU AssiY2K
by ur screenshot i guess that u r still using ics. i had same problem with my wifi and bt. try latest ics rom and in last pages of ics thread is a patch regarding wifi problem apply that too. i hope it ll solve ur prob

i will try that patch...i reverted to stock before and i had the same issues...hope that patch will help (which ics rom thread? LC, Virtuous or BeatMod?)
Okay,
I would try another ROM, not ICS. If the other ROM works with WIFI, then will be the issue to ICS.

well try to install latest virtuous rom and then install wifi patch.
i went back to stock and then flashed various ROMs and i still have the same issue...oh and btw, my phone vibrates twice now before booting up the ROM, then when the ROM boots up it vibrates for the 3rd time....never happened like that until i flashed a radio for the first time...so idk...i think that most probably is a radio problem...and i have no idea what i could do to fix it...it's like over a month now without WiFi and it kinda kills me T_T

[Q] Nexus 4 Radio Problem

I have been using Paranoid Android for some time now and yesterday i updated the bootloader and the radio and it has been nothing but problems since then no one seems to be able to reach me i am getting very spotty mobile data and calling anyone is a no go
i even tried reverting back to .33 and that didn't help has anyone had any similar problems or does anyone have any solutions
Same for me, I'm on CM10.1 though
Sent from my Nexus 4 using Tapatalk 2
Same problem here. I'm rooted and have an unlocked bootloader, on Paranoid Android 3.10 with Motley Kernel and Radio : radio-mako-m9615a-cefwmazm-2.0.1700.48 .
I'm getting very frequent call drops and it's very annoying. Can someone recommend a stable radio that I could use?
what carrier are you guys on? im having similar issues. im on tmobile. tried going back to .33 radio, but calling audio doesnt work on calls.
I'm using Virgin/T-Mobile in the UK, i've gone back to .33 to test it out for a while, calls are working, data looks good so far
Same problem with me,

[Q] Problems with WIFI & BT when using custom ROMs

Hi guys.
I bought my Nexus 4 (after selling me old Galaxy S2) a few hours ago and I'm running into some issues.
Whenever I'm on a ROM that isn't Stock, my wifi or wifi + BT aren't working. The WiFi status is always 'Turning on wifi...' and never changes, and occasionally its the same for Bluetooth.
I've tried installing CM11, Carbon and AOKP, changing kernels, even flashing the stock radio to see if anything changes, but it all stays the same.
Another thing I've noticed (I don't know if it has anything to do with the WiFi, but it could be) is that on AOKP and on the Carbon, I can't click the top right button in the notification bar (the one that shows you all the toggles).
The thing is that whenever I flash back to Stock 4.4, everything is ok, and both the WiFi and BT are working as planned.
I'm actually clueless after trying anything I could think of. Does any of you have any idea what's going on?
Thanks in advance.

Hello, you have to flash older radio to enable wifi. Try version 84. Just flash the zip from CWM.

Hi, thanks for the reply.
I noticed that a lot of my sensors are dead as well when not using a stock rom.
I've had nothing but Android devices for the past 4 years, but in this case, I don't know whether the radio solution can solve the problem, since it looks more like a Kernel issue, or am I wrong?
Isn't the radio supposed to affect only wifi and BT? What about the other sensors?
Will try that soon though, phone has 2% battery.

I'm having a similar issue. On nexus 4 phone with current stock ROM running 4.4.2, I tried Cyanogenmod 10.1.3 but wifi was always in trying to connect mode, never managed to turn it on/off. The same behavior is on miui ROM but on stock everything works fine!

If the custom roms you are using are based on 4.4.2 it may be a problem with the newer kernel. This article recommends flashing the 4.4 kernel as a possible fix.

[Q] Only getting 1.5mb internet speeds on 12mb

Hi,
This is an odd one.
I get 12mb download speeds on my home wifi if i do a test from my laptop or girlfriends iphone. If I do the test on my Nexus i only get about 1.5mb.
If I reboot the router (Draytek) I get the full 12mb again for a few hours then it drops right back down to 1.5mb.
Now I know you are all thinking straight away its the router but I have recently changed this from a Linksy router to the draytek and had the same problem with that one, so it would appear it is my Nexus.
I am running PA with the latest Kernal for it.
Any ideas or help?

In "About Phone" look for baseband (a.k.a. radio) version. But be careful, if you are using Jelly Bean ROM, your radio should be 0.84. If KitKat ROM, then the radio should be .97 or .98. Don't flash 97 or 98 on Jelly Bean ROM !!!

In "About Phone" look for "Android Version" if it's below 4.4 then you are on Jelly Bean (e.g., 4.3 or 4.2). I don't use PA ROM so I don't know which version currently for PA.

Have you tried to wipe cache and dalvik cache in recovery? Also did you test your phone in different area because it depends on where you are compared to the cell signal tower.

I found this information on Google's support forum:
I can hereby confirm that flashing back the radio from M9615A-CEFWMAZM-2.0.1700.84 (default for 4.3) to M9615A-CEFWMAZM-2.0.1700.48 (default for 4.2.2), whilst keeping the rest of 4.3, did NOT fix the wifi speed and connectivity problems on my phone.
I then proceeded to downgrade completely to 4.2.2 using the Google-supplied factory images, and I'm now getting 44 Mbit/s down and 5 Mbit/s up via 802.11n, where on 4.3 with either of the two radios, I couldn't even reliably finish the test (it would stop halfway, with the download speed estimated at 7 Mbit/s). Besides that, I've now been able to update tons of apps from Play, where with 4.3 this was not possible with either of the radios.
Just in case someone finds this, the version of Android on this Nexus 4 causing endless wifi problems is:
* Android 4.3
* baseband M9615A-CEFWMAZM-2.0.1700.84
* kernel 3.4.0-perf-gf43c3d9, 2013-06-17
* build number JWR66V
The version working well is:
* Android 4.2.2
* baseband M9615A-CEFWMAZM-2.0.1700.48
* kernel 3.4.0-perf-g7ce11cd, 2013-01-29
* build number JDQ39
You should use a different radio. I'd recommend the hybrid radios 33/84. Uses .33 radio for connections such as WiFi and data, whereas .84 radio is used for calls.

I am going to give you the best info you're likely going to get as I suffer the same problem.
Don't reset you're rooter switch wifi on and off on the phone as it achieves the same results.
After a while of doing this it will improve the duration it locks on to fast wifi.
Also I think relocking the bootloader helps WHY I haven't a clue.
All I know is I have the same problem with the newest and fastest wifi available in my area and after trying everything flashable, settings in wifi and even patching my wifi from roms with my wifi working the results are.
1 go back to a stock 4.3 rom.
2 try what I suggested.

Just asking, but are you sure you didn't confuse MByte/s with Mbit/s? (Notice the lower and upper case B )
It would make sense as 12Mbit/s are 1.5MByte/s.
Ok guys, just so you know, Radio/Baseband has nothing to do with your WiFi connectivity or the transfers speeds you are getting on WiFi. All WiFi modules, drivers are present in the Kernel and NOT the modem/baseband. Hope this gives you clarity and prevent waste of your time fiddling with the modem to solve WiFi issues!!

Flashed enough radio basebands and pulled enough files from the system to know where both live. I am talking about interference something causing the wifi to drop suddenly as if the network is strangled (but its not) there's a few phones that suffer the same problems as I have read all there posts.
It's something causing it to drop turning it on and off helps for a short time in my case about 3mins tops.
It could be anything I just find it a little strange that on a custom rom any soap ,cm and custom stocks this happens but not on a Google image. So something strange is happening who knows. Just wish I did.

Is Nexus 4 getting wireless speed over 2.4mb/s?
This is the maximum that I can see at transferring of files to PC on same network.
I can't have it locked over 54mbps at settings of wireless.

4.4.x update makes wifi not work

ever since updating to kitkat my nexus 4 is running in to a lot of issues with wifi, when i turn on my device wifi would work for about ten minutes and then stop, while still sowing connected to my home network but unable to load a page in chrome or send a message in whatsapp. if i downgrade back to 4.3 everything works fine again but updating again would do the same thing. even installing a custom ROM like CM11 would make wifi unusable while CM10.x would work fine.
