Custom rom removed service.

When I installed 1.35 liquid on my Galaxy Nexus I could no longer get 3g, 4g, or even make phone calls. In settings it says no service. Is there some step that I just didn't follow. Also when I reinstalled stock the service came back.

since you mentioned 4g, i assume you're on verizon?
did you update the radios to handle the 4.0.4 rom?

How do I install that?
How do I install that? I went to that website and downloaded the file. Do I just install it the same way that I installed Liquid(through recovery mode, install from sd card, pick rar and install)?

Tried and failed
I tried what I mentioned earlier and it didn't work I still don't have service.

then i would try a dfferent rom/kernel

Any Recommendations?
Any Recommendations? I am not sure what the difference is in kernals but I really like this ROM what kernal should I try?

They flashed a Maguro build. :facepalm:

make sure you picked the rom for verizon nexus (toro) not GSM (maguro)

Ohhh.
So the Liquid rom isn't compadible with the verizon version of the Galaxy Nexus? What rom should I use then?

liquid has a verizon version.

[Q] Baseband Unknown, Signal Drops

Hi, i'm from Brazil and i have a Gnex from UK, and it's unlocked.
When i was at 4.0.2, everythings ok, but after the OTA update to 4.0.4, i'm having some problems if the data is turned on, and the option 'only 2g' is checked the signal is good, but if the data is turned on and i have 3G connection the phone lose signal, and baseband shows Unknown.
My Gnex is Yakju, and i have flashed the 4.1 (JRN84D) from here with baseband I9250XXLF1 and 3.0.31-ge8de0e2 kernel ( on the post shows that's a stock kernel ). And the problems still here.
More info about my Gnex on fastboot mode:
Product Name: Tuna
Variant: Maguro
HW Version: 9
BootLoader: PRIMEKK15
Baseband: I9250XXLF1
Sorry for my bad english, but i can't use 3G connection and i need to recive emails, etc
If anyone can help me, thanks! :laugh:

I'm not 100% sure but I think your kernel maybe be the Developer preview kernel, the official is 3.0.31-g6fb96c9, you could try flashing that? It's what I'm running with 4.1.1 and it works fine.

The 4.1.1 is available from OTA, but when i press to install the phone reboot then enter in CWM and shows a message that de update was found, try install but give me a erro message that failed, i'm a new user on android, my phone was an iPhone.

No, when de signal is dropped i had to take battery out from phone, wait 5 or more minutes than put it back! If i put it back before i have the baseband unknown message on Config > About Phone. And this happens only if i have 3G signal, i see many people saying about signal issues after OTA to 4.0.4 and if i still with "only 2g" selected i don't have signal drop or disable the data, then i don't have any problem

If it's the status 7 error it's because OTA's require stock everything I think, including recovery.

Not sure if it will fix the problem, I think it's in the kernel you have as that's where WIFI is managed, however you could try and if that doesn't work change the kernel.
Instructions on how to update to official 4.1 are here however if you want to then accept the OTA afterwards when following Method 1 do not delete/rename /system/etc/install-recovery.sh and CWM will be overwritten by stock and you should be able to accept OTA's.
Note: If you don't want to lose your data then you could try skipping the "Wipe data/factory reset" step but do that at your own risk, I skipped it and it works fine though.

a "different" kinda phone problem(?)
I looked through most all of these forums and couldnt find anyone with the problem im having. Not sure if it's me or what...
My problem is that when I flash some roms, my phone doesnt work. (yes im on sprint and only using toroplus). Well, yesterday, for most of the day, everything on my phone worked. When I got up this morning, It hadnt charged, and I lost my dialing again. Some ROMs I flash start off. When I go to settings> about phone> status under "Network" it says "unknown" and under "service state" It will say "no service" then checking on "Moblle Network State" It'll say "unknown"", sometimes my phone number shows up, sometimes it doesnt, Most times I cant make outgoing calls and when anyone calls me, it does a half ring and directs my callers straight to my voice mail. Is anyone having this problem too? And if so, how did you fix it? It frustrates the hell outta me and I think I should just go back to ICS although I dont want to. HELLP!!! :-/
Thanks,
Ridge

P.S. I forgot to mention that Im on a Sprint phone and that Im running Houng81's AOKP Aug1 version Baseband: fg01, the kernel that came with the ROM, Ive even replaced them a few times and nothing does any better. Forgot to add this to my prior text LOL sorry, that just gave me away as a n00b huh? HEHE

Doing the OTA might solve it since it will update (i think) your bootloader to lc03, you still on kk15. If it doesnt, use fastboot and update manually. To run an OTA with cwm installed, you need to download the update.zip from dev section for the OTA you want to run, but do it through cwm (like flashing a custom rom).

I read in another forum that the "factory" folder is the efs on the Gnex, and maybe my phone was with this folder corrupt, if i get a backup of another Gnex thats everything is working and restore to my Gnex will be resolve the problem?

Thanks for this post. I bought my mom a sprint gnex for mothers day, and sprint is pushing a 26mb ota. I put TWRP on her phone and rooted. Do I need the stock recovery to do the update, does the update break root?
Sorry, not familiar with Sammy or nexus devices, I've always used HTC. And the nexus forums are kinda hard to navigate because of the way it's split up.

[Q] help! t989d 4.1.2 no signal!

hey guys, like the title says, ive flashed with odin fw 4.1.2 onto my t989d and everything went fine except for the fact that i dont have any signal now, it cuts in and out, when its on it shows no bars and quickly doesnt work again.... i flashed to 4.0.4 and that loaded fine with bars showing, but i really wanted jb for battery saving purposes. im a newb at this and any help would be greatly appreciated! i tried updating with kies from 4.0.4 and it said my firmware was not supported or something... build number is jzo54k.t989uvmc6
baseband is t989dtllg2. i also went into recovery mode, flashed cache and flashed the internal and still the same... please help guys! any help is greatly appreciated!

Try flashing back to an older radio. I I see you are on uvmc6 radio which is the newest.
http://forum.xda-developers.com/showthread.php?t=1895400
there is no spoon.....

I think you need to manually set up your apn settings. I always have to on 4.1.2.
Also, I had to use the new T-Mobile radio, the Telus tlle4 didn't work for me. Hopefully when Telus puts the update out they'll have a new radio. The tlle4 had better reception. The new radio works OK tho.
Sent from my cell phone telephone....

sorry, but how would i go about flashing these radios to my phone? do i have to be root? i really dont want to root or put cwm or anything on my phone... i just want it to be clean t989d official firmware...

I am not sure how you flash a radio if you aren't rooted with cmw or twrp recovery.
You would probably have new radio if you installed stock 4.1.2 and more than likely need to still set up your apn settings manually ....did for Telus anyway.
Just Google "jelly bean add apn settings Telus" or koodo, whatever you're on. The settings after installing stock are wrong.
Sorry, yes you said you have new radio. So should just need the correct apn settings.

[MODEM]/[RADIO] [20B] TMO D851 LG G3 Lollipop Only

I was having a problem trying to find the modem for my D851 here on XDA. There were many plainly listed for D855 and other models of the G3. I am using Paranoid/ASOP 5.1.1 Rom and I accidentally flashed a D855 radio. Rookie mistake, I know... And thought I backed up the modem along with the system files. Well I didn't and lost my imei, apn, signal and all... So while searching and again not obviously placed easy to find I read a thread and found one, flashed it, and it returned everything to normal without having to flash back to stock rom and blah blah blah... From what was listed, this for L 5.0 and up.
1. Boot phone into recovery, preferably TWRP
2. Flash the modem zip DOWNLOAD: https://www.dropbox.com/s/xz26z91hej9ryz3/LGD851.20B.MODEM-iNb4TMO.zip?dl=0
3. Reboot
I didn't make the radio, nor take any credit for its creation. I'm just trying to make it easier for T-Mobile D851 users on Lollipop to find incase they have deleted or lost theirs like I did...
I am not responsible for any issues or problems that may be encountered by using this.
I hope this help those in need like it helped me... Please let me know...

Im currently having a major issue with the lollipop update. I had my d851 with t mobile and I wouldn't lose lte when I would make a phone call... I currently switched to metropcs and now when I make a phone call I lose lte and my signal drops to 4g. I tried everything... APN, restoring the phone, called metro like a thousand times and nothing. Any help would be greatly appreciated.

Flashing the 30D modem seemed to help quite a bit, the signal will drop to 4g while you're on a phone call but the data is alot faster. Give it a try, it worked for me.

Well, I went camping over the weekend and of course the phone dropped service again. The cell signal was weak and the data was almost non-existent. Luckily I brought an old phone, re-activated it, and was good with LTE signal. My question is would flashing a different modem help? I have the LG-D851 with SW version D85130e so I assume that has the 30e modem. Is that correct and would the 30d modem be better? Thanks.

No idea. Could be something else (mechanical) causing the issue. 30e is the latest for our phones. You can also drop it down to 30d & see if it is any better.

That's what I was hoping to do but was trying to see if there was a way to just install the 30D modem instead of loading the entire phone with the older SW version and having to re-install all of my apps. I downloaded the modem file but after doing some research I couldn't figure out the procedure to install it. I saw a few videos about a TWRP recovery but I prefer not to root my phone. If I have to root it in order to get it working then I will...I just wish I could figure out what the issue is. I saw a few other people mention issues with the LTE setting defaulting back to WCDMA/GSM (which I experience) and they said the 30E modem could be the issue. The phone was just wiped clean a few months ago before I bought it from the previous owner.

If I have to root it in order to get it working then I will...I just wish I could figure out what the issue is. I saw a few other people mention issues with the LTE setting defaulting back to WCDMA/GSM (which I experience) and they said the 30E modem could be the issue. The phone was just wiped clean a few months ago before I bought it from the previous owner.

yeah without having root, your options are limited. If you own the phone, I would say go for it, if you are leasing it, then take it back to where you got it & tell them it's reception sucks.

I own it and bought it second hand. According to the previous owner he didn't have any issues with it but who knows. I assume if I root it and load the 30D SW I will have to load everything from scratch? Is there an LG backup program for this phone? Thanks for the help.

Review the warning information, then tap OK to confirm.

I have the TMo version (D851) & the first thing I did was root it & install a custom ROM to get rid of all the Tmo crap that is stuck onto it. ugh! I don't use my phone all that much for calls, mostly emails data & music playing, so losing the stock Wifi Calling function wasn't an issue for me. Currently on the OctOS Nougat weekly builds, tremendous ROM, great battery life fast & smooth & decluttered. Since you already own the phone & do not have a warranty, you've nothing to lose here. Do some reading in the threads on how to do it, you'll be very happy once you see how much better your phone can be. You put on it only what you want to put on, less junk, less memory hogging.
