Possible workaround for the GSM issue - LG Optimus 3D

I have been struggling with the baseband locking up and makes the phone stop receiving and sending calls and sms.
On a hunch I disabled HSPA (2G data only) two days ago and it haven't happened since. This was on cyanogenmod nightly. I missed out on some key issues from the original ROM so tonight I installed ThaiZ ROM. Will report if I get the same success with this.
This is not a good solution but a working phone is more important to me than fast data. Until LG releases new baseband I will turn on high speed and reboot afterwards when I need fast network access.

I did this quite a while ago and it's a proven working method.
Reports say that the official 21B solved this issue, which is due to the way phone.apk handles network switching.

I'm using the stock V21B and I haven't had any network issues with it.

Official Australian Optus GB rom available...kind of...

As some of you may know, my O3D was sent to LG service repairers Evertec to fix a broken power button. I asked them to fix just the power button under warranty - my phone was on froyo (i was on the leaked GB but because of ghost calls and data dropouts i reverted to froyo) and i just got my phone back today with a note saying the power button was fixed and they flashed my phone to "the latest firmware"
Lo and behold I booted to a fresh install of an official Optus GB rom - baseband 20b but perfect reception. no dropouts or ghost calls. i think it may be rom related.... i do have some bloatware but at least i have no reception/data issues
im not sure if this rom is available ota or for download but the service guys seem happy to flash it on repaired phones!
yes,20b is online,but still not rootable
I had 20b installed before but it wasnt the Australian Optus rom... Whatever rom that was, it always gave me grief....now no problems at all. in fact optus even sent me a message with settings in it - i havent activated it as yet as my reception is currently working perfectly fine without it.
Guys, please be aware that LG version numbers ARE NOT CONSISTENT, at least not the way we think of it. European v20b is not the same as India v20b.
In fact, each region has it´s own version branch, so you can perfectly have, for example, Romenia v21a with the same baseband of Croatia v20b.
So, don´t be fooled by equal version numbers: you can only compare version numbers when comparing software for the same region. If you cross regions when comparing, you will get it all wrong.

I installed the same rom as you, 20B Optus, took my external SD out and formatted the phone to factory, for one day the phone worked well then the problems started as before 3G getting stuck can't go to airplane mode I had to restart the phone, after it happened over 4 times I installed froyo. Same thing exactly happened to my friends O3D, Evertec changed the board on my phone when I took the phone for service for the random rebooting problem, now it is very hard to sell the phone if I tell the potential buyers the phone was serviced. So I am stuck with it.
I use it like Thiaz as a media device now and I use My Iphone 4 as my main phone.
what is the use of a phone if it can't be used as a phone?

I noticed you're posting from a 925... Mines a 920.... I never had a random reboot and I've installed the Acura and Thiaz roms - used stock roms, OC'd and the only GB rom working properly is this one....
I'll keep my fingers crossed that it stays this way....
Admittedly I never had any issues on Froyo - If this rom does play up I'll downgrade asap. I won't miss the GB features all that much

You noted correctly, but my one is an Optus 920, I was so desperate so I am using Froyo Baseband and the CM GB for the 925, this was my last resort, the phone works very quick with no lag, and I charge once a day, hdmi does not work, and I can't view photos in 3D, but this phone is good for playing games, that is all I use it for.
I have intalled the update to my optus lg optimus 3d thought lg update tool, i have had 2 missed calls i did not receve that i know of and really bad battery life. i might have to do a factory reset if this does not fix i will not be happy.......back to lg

Good Luck mate, they will tell you that you are the only one in the world that is having this problem, all the staff at the LG service center (evertech) are using GB without any issues what so ever.
you will be told (you are special)
Ok... Here's the weird thing - I know people seem to be having problems using this rom... I am not one of them (so far) I had issues on every other GB rom but this one. Maybe it's related to signal strength, carrier specific settings or something else. I really can't explain my lack of issues. I do set my phone to 3G only - as I don't want it jumping from 2G to 3G but that's it as far as any phone changes.
*I am using the Optus GB rom on Virgin Australia (they piggyback on Optus - slightly different settings but same network).

Please keep us posted, I am on Vodafone and the signal is shocking where I live (inner west) Vodafone will be updating the network next month.
but I do not have any issues with my iphone at all, and when I go to my other house (castle hill) where the signal is perfect -50 db I still get the baseband crashing.
I used the phone for 2 weeks back in November when they released the Europe Open before I stated getting complaints that I am not answering Phone calls and I missed out on couple Jobs worth over a grand!!!
Quick update.... 1 week later and still no issues - strange but true! No missed calls (that I'm aware of and no loss of data... Perfect reception... For virgin mobile customers on Optus GB rom - no issues.
GPS lock perfect - regaining signal after airplane mode perfect, over 400MB in data in a week and no loss of reception, perfect... This is the only rom that works for me on GB without ghost calls, internal reorganizing crap or loss of reception/data
I can't root and have some bloatware but I can live with that...
Will update if things go bad but for now I'm VERY happy!
Thank you so much for getting back to us, I will be trying the 20A Australia again, this time around, I will take the SD card out, will fully format the phone and only install couple important apps that I need, I am doubtful but at this stage I am willing to try anything. will try the 20A for 3 days and will report back.
Edit:
Day one: No Freezing and no missed calls at all.

AT&T Microcell Issues

Looking for any suggestions to solve my Microcell issues. I'm running CM 7.1. I have tried the 12.39.60.19U_26.06.04.06_M Radio and RIL and currently using the 12.56.60.25U_26.10.04.03_M radio and RIL. Just about everything works fine. Battery life is acceptable, cell tower usage is fine, wifi, bluetooth work fine. My only real issue is when it is connected to either of my two Microcells. It regularly drops calls. It can drop the call anywhere from within the first minute to after 10 minutes. Not really predictable. Any ideas on what else I should try? More radios, different ROM, tweak some settings?
I have same issue on my Infuse. I wont get some of calls when I connected to microcell. If people leave voice message, i will receive them, else its like no one called me. but the caller thinks, i am not picking up the call
I dont know, whether its Custom ROM issue or Microcell.
I think its microcell, because last week when I tested, even my friends stock phone had missed some calls, and my wifes samsung focus also.
but their miss rate is very less compared to my infuse.
Reports of problems with microcell after flashing?
I've done some googling but haven't found anything definitive regarding my concern: What effects might flashing a new ROM have on using my At&T microcell? NOTE: In the past I've flashed new ROMs and not had any problems connecting with my microcell.
The other day I was having stability problems on my Inspire, so I reflashed the de-bloated latest AT&T update (which I had been using already) and for some reason since then I haven't been able to connect to my microcell. Today I flashed a matching radio and RIL in case I had flashed badly matched ones and I'll be checking on the success or failure of that tonight when I get home.
I did find some rumors that flashing a new ROM might cause the microcell to no longer recognize the phone, although it still has the same IMEI and it has the same phone number (obviously) so I don't know how that might happen.
Last night I deactivated and reactivated the microcell and made sure the location etc. are correct, and that didn't seem to have an effect.
I've been running the sabsa ics roms by alirez, and have had no issues with my microcell.

[Q] Radio disconnects!

Here is whats happening! I go into an awful area with no cell service and when i return into an area with good service... It shows all my bars, 3G icon, but its all grayed out and will not return with color... Also i have no data connectivity at all. The only way to resolve this problem is a reboot. I have the Nexus s 4G KL1 radio... This has happened twice in 2 days. Can anybody tell me what this could be? I tried the KL2 radio and the same thing happened. So I went back to KL1. I am running Cyanogenmod 7.1 stable. Any help would be appreciated, I like this phone and dont want to have to go back to my slow Evo.
Happens on ICS ROMs. I switched back to GB because of that issue.
OHHH ok that makes sense since i was on an ics rom... That sux i love the ics roms to. Is this an issue they know about and are working on?
Yes I am sure the devs know about this issue. A lot of people already reported this issue on the ROM's threads. I think there was a fix in the CM9 repositories that was merged this week.
well thats good news since were i live its not good service and im in and out of service a lot. Thanks for chiming in and letting me know! I was wondering if i had a bad radio or some thing lol...
This happens to my I9020T as well (with stock ICS, Pixel ROM, and Brainmaster's Stock and MIUI ICS ROMs). So, it's definitely an ICS issue. My network connection won't reconnect after I ride the subway (underground, where there's no signal) for about an hour. The only way to fix it is by doing a reboot (enabling and disabling Airplane mode doesn't fix it).
I just tried switching radios: from KI1 to KF1. I'll update on the result later tonight.
Sounds like exactly what happened to me.
I went back to gingerbread. I haven't had the issue since!
Just out of curiosity have you tried the KL2 radio with CM9/Latest nightly and then toggle your Data Enabled or the data roaming? If that works it might save you the reboot. Settings, wireless & Networks/more, Mobile networks, Data enabled.
You could try toggling the data roaming too.
Yup tried it already

I've tried enabling-disabling Data as well, and it doesn't fix it.
The weird thing is the same issue happened to my girlfriend's T-Mobile G2 with Gingerbread last week, when I unchecked the "Use only 2G network" setting on her phone and forgot to check it back. So, when she told me the issue when she got home, I re-enabled the "Use only 2G network" setting again, and her phone haven't had the reconnect issue ever since.
So, my speculation right now is this reconnect to network failure issue has something to do with the Nexus S' 3G/4G network type setting.
I definitely think you're right
I am having somewhat the same problem.
My phone keeps switching from UMTS:3 to HSDPA and back to UMTS:3
This is draining the hell out of my battery. But when I have it on EDGE 2G I'm getting good battery life.
the issue is not that big for me. I just give it a few moments with it in sleep and when I go to use it again it fixes its self.

Update!!!! I have since switch off of the I c s rom. I have not had the incident happen even 1 time since doing so. I am totally convinced it's on ice cream sandwich roms.

I doubt the radio would make a difference. I think the issue lies in the Phone application.
I could be misinformed here, but if i recall correctly, our phones radio is relatively stupid as far as radios go, and the intelligent parts are actually done as a part of the phone application. This only applies to CDMA Variants of the Nexus S, but it could be the reason that the ICS update was pulled (As thats where CM and others get the ICS version of the phone app.).
After taking the subway for about an hour last night, my NS actually reconnected when I got back up to ground level. One thing that I didn't do is listen to music (PowerAmp); I was always listening to music when I had those network reconnect issues.
Anyway, I hope this issue gets fixed in the upcoming official Google ICS update, that should be released in a few weeks*.
*http://www.engadget.com/2012/03/15/confirmed-ics-coming-to-the-nexus-s-in-the-next-few-weeks/
I've found that if you just stick it in airplane mode when you are about to go into known no service area and then take it out of ap mode when you know you have a signal you can save from having to reboot to reconnect.
My building at work is a tomb for sprints signal and it works for me every day w/o rebooting ...
To all of you having network reconnect issues -- do you use any battery saving apps, like JuideDefender or GreenPower? I use one, and I'm thinking that its network toggling internal API method has something to do with this issue.
Yesterday, I disabled my GreenPower app right before I took the subway, in which my NS couldn't receive any network signal for about an hour. Then, when I went back up to ground level my NS was able to reconnect to my network successfully.
I'll do the same test later after work and update back tonight.

[Q] No signal strength all of a sudden

Hello,
I bought my Nexus 5 on the 11th of December 2013 and it had been working flawlessly ever since. Since last week, I started noticing the occasional signal drop and I'd be out of cell reception but would usually be back up within no time. However, yesterday, out of the blue I'm travelling on the highway and my signal strength disappears never to come back again. I've tried the following:
- Restore old backup (including EFS)
- Went back to stock from PA
- Upgraded to the latest radio
- Took back cover off to see if anything was wrong but found nothing.
- Tried another SIM card
Nothing worked. My SIM card works fine in another phone. Everything else such as WiFi and Bluetooth works flawlessly but I just don't get any reception.
This is very disappointing and I have my fingers crossed hoping someone can help me with this since I didn't plan on getting a new device for at least another year especially after paying $520 USD for my phone here in my country.
Thank you for looking.
im having a similar problem with the radio after the last few otas. im getting a lot of dropped calls on 3g aws...
im going to try to revert to an old radio as i don't think this is a hardware failing issue..
Sent from my Nexus 7 using Tapatalk
Flash stock firmware with fast boot. If its the same, its a carrier issue....call them to see. Or its hardware failure.
just wanted to post my fix for this issue - very disappointed with Google that i had to do this...my provider is mobilicity canada (3g aws band fyi)
flash krt01b radio from this thread...
http://forum.xda-developers.com/showthread.php?t=2514095
this is *not* a carrier or hardware issue (at least in my case)
seems others are having same issue
https://code.google.com/p/android/i...s Owner Summary Stars&groupby=&sort=&id=70878
Then it is a carrier issue....cause on Telus in Canada....never had an issue with any radio version. ?
telus would have a stronger overall signal but uses AWS band for lte which is different than mobilicitiy 3g aws...
I'm not disagreeing.... Just saying its the carrier....not Google.
See my point?

are you saying mobilicitiy is purposely weakening their cell signal cause they are almost bankrupt ?
i still blame google i had no issues with the radio before they borked it...

Just saying that unless many have the issue with the phone or radio, then its an issue.....if not, it isnt .
So in this case, it leaves hardware or carrier....assuming a stock flash didn't help.
If flashing another radio helps the OP...awesome!! But the new radio does work fine for the mass majority.
Hope it does work for him tho!

[Q] My D820 won't even detect my network

Hi people,
So here is the thing. I brother gave me a D820 purchased in the USA and I was using it just fine until one fine day, it stopped seeing my network. It supports the GSM frequencies at 2G and 3G but it isn't even discovering the network.
On Vodafone India - Now, even when I do a manual search, my network isn't visible. It was working fine earlier but it just isn't now. I have tried everything from reflashing the whole thing, to trying out a custom ROM like CyanogenMod, including the CAF builds.
I have also tried flashing the old radio and that didn't help either.
On Airtel - What is funnier is that I used another network's SIM card and it seemed to be working perfectly for a few days and then the same problem appeared there too. Only this time, it was seeing the network, only wasn't registering on to it. It couldn't be a network issue because the same SIM card worked perfectly on another device.
Request any help to resurrect my paperweight Nexus 5 into being useful again.
Thanks in advance!

So you need to give more infomation. A lot of the stuff you're saying is pointless for example (I also tried flashing the ld radio???) there are a lot of radios for the nexus 5. (reflashing the whole thing???) what ROM were you on? what kernel? when and how did it stop working? what were you doing?
Be happy I replied lol it seems like you wrote the post in one big panic of a mess. so go ahead now.

You're right. I was in a state of panic.
The problem just happened. There was no reason for it, nothing. It just stopped detecting my network.
I have tried the following builds. And radios from these build separately, because as I understand, there were some WIFI issues with Lollipop to begin with:
1. KTU84P
2. LRX21O
3. LMY47I
More pointless info: Apart from these I have also tried the latest CyanogenMod 12.1 NIGHTLY (cm-12.1-20150419-NIGHTLY) with the CAF kernel and the standard CyanogenMod 12.1 AOSP NIGHTLY build.
what ROM were you on? - I was on stock KTU84P when the network stopped getting any sort of detection from the device.
what kernel? - Stock kernel that accompanied the above ROM. The phone was not even BL-Unlocked or rooted.
when and how did it stop working? - The when is a week ago. The how is a mystery.
what were you doing? - Nothing. I just woke up in the morning and found that my device has no service. Then I tried a manual network search and my network wouldn't show up. It works perfectly on other devices, the SIM card that is.
So, now I have a phone that doesn't work on my network.

My wife's Nexus 5 D820 has the same issue. Network worked fine on 4/13/2015, but zero network service the next day, 4/14/2015.
Did your problem happen on the same day? Are you on StaighTalk also?
Her phone was on stock software and still locked. Tried everything and figured it's a problem with the phone since putting my sim card in her phone didn't fix the problem. The phone detects sim cards and their registered phone #s, but zero network service. My guess is the cell antenna hardware broke.
We bought a different phone. Wish we could fix it! It would be nice to fix this Nexus 5 that functions fine except no cell service.

Hey, I have the EXACT same problem. My Nexus 5 wont detect the Vodafone network in India! I tried all kinds of stuff - flashing the original stock rom, factory reset - nothing worked. All other networks are working fine. The same vodafone sim that wont work in the nexus is working absolutely fine in other phones. I am at my wits end - did you find any solution to this yet? Please let me know.
I have also been facing the same problem on vodafone.50% of the time i am unable to make or receive calls even when signal is present and if the call connects the call receiver cant hear me.The problem is also present in al the other ROMs and rradios i have tried.
