Loss of signal - Nexus 5 Q&A, Help & Troubleshooting

Hi, I have loss of carrier signal frequently on my nexus5. I have to reboot the system to get signal again.
There is installed cataclysm 10 September, with blue spark 3.40 and base band M8974A-20.50.2.27.
Someone can help me?

Try another modem, carrier, rom, kernel...
Did it already happen in the past?

Can I downgrade to kitkat radio even if I have 5.1.1 cataclysm rom?

Yes.
Radio is completely detached from the OS version. Flash radios until you find one that works best for our device.

[Q] After flashing latest Synergy, network show up as empty

I still have my IMEI nmber, it is not zeroed out, but network would show up as empty, and there is no mobile network it says disconnected.
Anyone can help ? thanks!
Also sorry, using latest Syngery build and I have no problem with like the Jelly Bean R14 build at all, and old Synergy rom R143 works for me as well..
Is that with wifi on? Mine says disconnected when wifi is on. Turn it off and shows connected

Did you flash the VRBMB1 modem?
I had a similar issue when coming from R143 to R420, I flashed the new modem and wala it was fixed.:good:
I'm now running R443 and I have no issues using the VRBMB1 modem.

Oh I was thinking about that. But I thought r433 has the newest modem so that s what I should use..so which one did you download.
It is not a WiFi on issue but I don't see carrier issue.
Modems are never included in roms. Go to settings -> about phone and look up your baseband version.
You can find flashable modems here

4G never going above 1 bar...

Hey guys
I recently got into the s3 (I know, I'm late to the game...)
I am using the latest elemental X from Nitro...and I love the ROM!
The one thing I noticed is that I can never get above 1 or 2 bars on 4g. Speedtests never go above 4 or 5 Mbps. However, My Bionic will do 25+ in same area.
Any suggestions where I should start investigating?
Thanks!
About the only thing I could suggest is to try another modem and rpm

How was your signal on stock ? ROMs don;t change the radio, so should be the same. Did you make any other changes?

Hmm, to be honest, it seemed ok...
Here is what I did when I got the phone...
I ODIN's back to stock 4.1.2, rooted and unlocked bootloader.
Went into clockwordmod...wiped etc, installed elemental X, and gapps.
Should I have done the OTA update 1st?
I just checked the baseband version..., it says "I535VRBLK3"
Could that be it?
Elemental is aosp right ? If it is then that's you're answer . try a touchwiz ROM and you'll see the bars falling off your screen . tyres ROMs have to do with your signal . touch wiz ril will always be superior to aosp's ril.

Your modem should be VRBMB1 , you are on an older modem/radio version
You should install the latest OEM verizon 4.1.2 full.
Then root and install the ROM you want.
The radio is the radio and custom ROMs shouldn't mess with your actual signal if you install via recovery, but GUI changes to the status bar may cause the display to be different.
Thanks....Thats exactly what I just did....
Stock ROM still giving lousy signal....speeds aren't that much better...
Ill try a touchwiz rom also...

And your modem version is? Data rates might get a little boost from some tweaked ROMs, but actual signal strength won;t, it simply doesn't because custom ROMs still run the stock modem and radio. And the stock ROM IS TW . when I run stock , I get 25+ mbs down in a 4g area, same as on Synergy custom, even when I have only 1 bar I get 10 mbs down

Hmm, forgive me, but which would be the modem version?
I put everything back to stock, rooted for now....
Thanks again my friend!
ive read that hte AOSP roms show less bars but get similar signla.
ive seen it in practice when with my mother.
check the signal strength on TW, then on AOSP and see if theyre equal. my moms stock S3 gets the same signal as my aosp phone does in our location.
Go here. Download the latest. It is an all in one. With the latest trust zone. It may alleviate your problems.
Or not.
I am running the PACMan ROM. And it shows less bars. Yes, it annoys the living daylights out of me. But, the speed is there when I use it and do speed tests. Any way, good luck.

3g issues after flashing NEXESQUE ROM

After flashing this rom my 3g signal is always very weak or nothing, while the gsm is full all the time. Any help? (sorry for my English)

If I remember right this is bug in nexesque rom.
It may be this, because before flashing it had been working fine. I'll try changing the rom.

did you flash the patch for the gsm?
because i did that and my 3g signal was all wack.
and after that patch even the signal on the other roms i flash stayed the same.
only 2g works fine.
so it may be this

I flashed the gsm patch and I was still not working. Now I flashed other ROM (cyanogen) and the 3g is working fine. It should have been something from NEXQUE ROM :/
NEXQUE is for BL locked phones, to provide vanilla Android experience as much as possible. Enjoy in AOSP, CM or any other rom (Carbon as my favorites) for unlocked BL

Just use older carbon build and fix camcorder hiss sound (if you have) manually. I use 20140423 build.

no mobile data sometimes

I lose signalevery now and then and it never happened before.
Maybe its because of 4.4.4?
I had it with Mahdi Rom and elementalX. But now Im stock 4.4.4 rooted with f55 and jt still happens.
Should I change the modem?
Have you tried testing out other radios? Couldn't say if modems are included with the radio, but I've noticed signal strength differences depending on what radio I'm currently using.

Cm based roms mobile data issue

Hi,
I have a weird problem in my nexus 5:
Mobile data is not working in CM based roms, wifi works great.
I have tested many roms (CM12, CM13, Resurrection remix...) but always the same thing: no connection.
APN settings are ok. Roaming doesn't help neither.
AOSP based roms are working without any problems.
Does anyone has a clue what should i do to fix the problem? I live in Finland and carrier is Saunalahti.
Thanks in advance!
Data is fine with stock ROMs? Bootloader and modem is compatible with my ROMs you flashed to the phone?
