Nexus 5 "No Service" Cell Radio dead - Nexus 5 Q&A, Help & Troubleshooting

I wasn't going to post this, but what is happening to me seems to be more than just bad luck.
I am still having issues. I have three 16GB nexus 5 on December 16th and a 32 GB nexus 5 on December 27th 2013. They were all brand new, the boxes haven't been opened.
Last weekend (mar 1st 2014) my wife's phone's (nexus 5) radio just randomly died. it had "No Service".
We swapped simcards, still didn't work. SIM card was fine.
The simcard from the dead phone, worked on another phone. But a working SIM was not working on that phone.
I factory resetted the phone. Rooted the phone, to reload the Modem image, nothing happened. Loaded Cyanogen v 11, nothing.
But I then went and sold my phone of on Kijiji for $200 and bought a new one instead.
This Week again (7 days later after the death of the first phone), my phone died (2nd phone). Same thing. No cell network (it was working today morning, did at around 11am), No Service.
You cant connect to the Koodo Network even if you find it on the network list manually.
Koodo said it is an hardware issue with the Nexus 5.
I tried a SaskTel sim, same thing. Doesn't work on the phone with dead radio.
I called LG, they keep sending me to the cell carrier to get warrantied. And Cell carrier, sends me to LG, and Repeat..
FML
Now I am just waiting for my other 2 phones to die. If all four phones die, then there is something really wrong.
Does anyone have any suggestion to bring the radio back up?
(It is funny when you call Tech Support for the phone, they say "please remove your battery and put it back in again".. Lol. Nexus 5 battery is not removable.. duh!)

This doesn't sound like a dead modem, but more like a problem with your network. You say you can see Koodo Network in the network list, if that's really the case, your modem is not dead. Is Koodo perhaps blocking your ESN from connecting to their network? (This is independent of sim card). There are not a lot of reports of Nexus 5's modems going dead, and the fact that you had two do this really suggests a network problem. Can you switch to a different provider? Lastly, when you go to system settings, about phone, do you have a baseband version (modem softwre) listed? I have had phones randomly lose their modem software (although very rarely). Can you also check and see if the basebands are the same for the working and non working phones?

[Q] HTC G1 unlocked no reception

I got a used G1 almost a year ago, unlocked it so I could use it with AT&T and it had been working without any trouble until this past Sunday. I was running 1.6 for the longest time and never got around rooting it or installing mods. Suddenly, after I was on the phone for 2 hours, the G1 stopped receiving service. It was normal for the phone to drop service for a moment because of where I live, but after a couple seconds I usually get service again. I didn't.
I swapped out my SIM to an older phone and I was able to get service. So I figure it probably isn't a SIM card problem.
So I put the SIM back into the G1, browsed through the phone to see what was wrong and suddenly found that I had an "update all" button for the market. That's a feature only in 2.2, not in 1.6. I checked online to see if there were any updates to 1.6, but didn't find anything. I had no service, but a feature not in 1.6 on my phone.
After several hours of having no service, I decided to root my phone and install Cyanogen Mod 6. I thought maybe updating the phone might fix the problem. Hours later, I got CM6 up and running and used my brother's SIM to activate my Google account. It just so happened that when I was activating the phone, I had a small window of reception. After that, no service.
Monday I went to the AT&T store to see if they could help and my phone suddenly worked inside the store. I left it there for 15-30 minutes and service didn't drop, so I thought it was fixed. I left and just as I got home, my phone stopped working. So I drove back to the AT&T store to get a new SIM. Sad part is, my phone has service in the store. Again. I just don't get service anywhere else.
I got the new SIM, but I still didn't get service. My brother suggested that the antenna cable might be loose. So yesterday I went to pick up a screwdriver set that had the right size torx bits so I could open up the phone. The cables looked fine, but I pulled them out and plugged them back in. That didn't fix the problem. I still didn't have service.
Late last night, at the CS club at school, a guy with a G1 on T-Mobile put his SIM into my phone to see if it would work. After 5 minutes, my phone was able to connect. So I swapped my SIM back in, but no service. My G1 can see the networks. Right now, I can see AT&T under "Available Networks", but every time I try to connect, it says, "Unable to connect to this network at this time. Please try again later."
I'm using a spare phone right now, but I'd really love to have my G1 working again. Any help or suggestions would be greatly appreciated.
Same Problem
If it makes you feel any better.. 7 months later and I have the same issue. Been scouring the internet and XDA for hours without any resolution. Maybe AT&T is dumping IMEI #'s for devices not in their lineup? Older AT&T Sims seem to work though which is strange. Maybe this bump will get us some kind of response.

Galaxy Nexus LTE Won't Hold LTE Signal

I'm posting here on behalf of a friend because I've tried everything I think I can do to help, but to no avail. I'll try to make this quick.
My friend bought a Galaxy Nexus LTE in December and it worked great for a few weeks, until the vibrator in the phone broke - he took it to a VZW store and they replaced it for him.
Upon receiving the replacement phone, he was having trouble with LTE staying connected. It would continuously drop and instead of falling back to 3G, it says he has no signal - signal indicator in settings displays a red bar (i.e. no coverage).
He took it back to VZW and they tried his SIM card in an employees phone - same issue happened to that phone. They then tried his SIM in a new phone off the shelf, same thing happened again.
Verizon is saying it's an issue with something at the account level, but I've encouraged him to go in and complain until they give him another replacement, just in case. However, it's very odd that his SIM card in three different GNex devices produces the same issue, even though his first one worked great. They have said that a future software update would fix this.
The other day I installed the leaked 4.0.4 update on his phone to see if the new radios would work, but the same issue kept happening. So I reverted him back to 4.0.2 so he could take his phone back to Verizon and beg for another replacement. Unfortunately I forgot to re-lock his phone so I still have to do that before he takes it in.
Has anyone ever heard of this before? It seems so odd that his SIM card would do this, but I still think that Verizon owes him another replacement device since he has a phone that isn't working like it should. He's getting a big discount on his family plan but he'd prefer to have LTE on his new phone.
I would love your thoughts - this just doesn't make sense to us. Any suggestions other than replacing the phone again? It sounds like VZW doesn't want to do that for him so it might be easier to fix it another way.
Can't speak for Verizon itself, but I have been through several SIM cards now on Telstra. Same issue, all of a sudden they are unable to pick up signal at all. Seems the pre-paid cards are more susceptible.
I'd ask for a replacement SIM, as opposed to a replacement phone as it's been proved the issue exists on multiple handsets already. If a new SIM doesn't alleviate the issue, the VZW rep may be right in that it is at the account level.
Good luck!

SIM card swapping

Luckily this is a curiousity question as the urgency worked itself out.
I have my Doubleshot connected to the Rogers network here in Canada, and I've tried other SIM cards before (i.e. T-Mobile) without issue. But this one had the representatives (and tier two support) stumped.
I walked into an Eastlink store (competing communications company although their roaming is done through Rogers frequencies) with a promotional flyer. We got talking about switching, and they offered to do a test to see if the phone is compatible. So I thought, hey, why not? So they popped an Eastlink SIM in my phone, turned it back on, picked up the network no problem. Well and good.
The problem occurs when she put my Rogers SIM back in. Boot the phone up and the network wasn't recognizing. No service. We went to Settings > Mobile Networks > Network Operators. The searching took forever then threw up and error. No networks to choose from.
The interesting part is that the Rogers APN's were present. I thought maybe the SIM card went bad. Luckily the Rogers store was across the street so we popped that into a feature phone, no issues. I then thought there was some weird (new) setting preventing it from connecting. So I booted into recovery and restored a backup from three days ago. No luck.
The problem ended up fixing itself, about an hour later, while waiting for the bus (after having given up). I made a few test calls to be sure. Since it's working now, it's merely a curiousity, but the issue stands: what would have caused this and is there any way to restore service faster? Using Tbaldens CM 10.1 if that helps.
Thanks for your thoughts.
Still very interesting. I find now that every time I reboot the phone, it takes a few minutes for service to be established. Long enough for Auto Pilot Mode (one of the apps I use in case I'm in the depths of big buildings) to be engaged. I may have to quarantine that app for a little while. Or just not reboot the phone.
My Rogers SIM is an older card. It would have been pressed in 2007 or 2008 (which is also why the fastest internet I can get on it is EDGE). It may be time I shell out the $10 for a replacement. For whatever reason, that just may fix this newly attained lag on connecting.

Just activated a new Rogers (LTE) SIM card. Booted up the phone, and service was recognized by the time I entered my login PIN. So everything looks good (as it looks like my old SIM was starting to die). I'm still stuck with EDGE, but that is due to the phone being a non-Rogers phone. No big deal there.

Oops network stopped working

Wake up this morning phone is cool, all apps I need setup and working. Really liking the phone.
Wife goes to store, comes back and said she tried to call me and it went to my Google voice account. Phone never rang. Try to call her, nada.. says I have a 1xRTT connection which is weird.
Phone is dead for cellular network access.
Contact support, nothing works, reactivate my Nexus 5x and everything works, so it is the Pixel. Have to go in Monday to get it replaced. Will use the Nexus 5x in the meantime.
Pixel was on 7.1.1 completely stock bought from Verizon online.
Today went to a store to exchange the phone. I had factory reset the phone first.
When I got there they only had 1 left. The sales person said let's change the SIM first to see if that fixes the problem, new SIM and seeing a good LTE signal, it works great.
Get home and reload my apps etc, go to make a call, back to square one. 1xRTT, no cellular network, no calls in, no calls out just like on Sat.
Now no stores have pixels in stock, cute.
Jan 5th is the earliest I can get a replacement.
Might just cancel the entire order as I have now had a Pixel since Wed that I can't use and it will be 2 weeks after I got the original before I get a replacement.
Either
1. The phone is bad
2. The tower by the house has issues though my Nexus 5x works ok
3. The Pixel doesn't do well with LTE?
I've heard that there are users in other countries with LTE issues, but not around here.

Can try turning Enhanced 4G LTE off (or VOLTE) and see if that works. Or, maybe turn it on if it's off.
Tried that both on Saturday and again today after the new SIM was pot in.

I Am very frustrated with this phone....

I bought this phone off Ebay about 3 weeks ago. It was labeled as a d820 The listing said for parts does not read sim card but everything else worked. Being Semi decent in the tinkering world I thought I would spend the 40 $ on the phone to see if I could make it work. When I got the phone it was on the setup screen because it was just factory reset. When I put my sim in (T-mobile) it showed that it had a signal. As soon as finished setup it lost the signal and could not connect again. So obviously it is some kind of software issue. So the first thing I did was try to update it from lollipop to marshmallow. Once again it showed it was connected to my network until completing setup. This time when I was in the bootloader I noticed that it said it was a d821. I figured well I paid 40 dollars I was probably going to get ripped off somewhere. So then I started reading about how to use the d821 in America thinnking that was the issue. I tried the qpst thing where you add the additional bands- nothing. Then I messed around a bunch in the cdma tool after reading a thread about adding cdma to the device. I also tried flashing various modems and roms with no luck. Last night I thought maybe theres something I missed hardware wise in the phone so I opened it up. I checked all of the connections and everything was fine. I started reading the numbers and got really confused. On the back of the phone it says d821 under the lg logo. but on the inside of the back cover and the plastic shroud on the motherboard it says d820. This might be irrelevant but it would be super great if someone had an idea of how I can get this to work on T-mobile in the USA because with a decent rom this phone is wayyy smoother and faster than my 5.5" alcatel idol 3 network unlocked from cricket (So lte sucks). All i want is a phone that has a stable lte connection XD
ANY ideas how to fix my D821?
The model # in the bootloader is the correct model #. Is it possible the imei has been blacklisted?
On the motherboard, near battery connector there is info about 32/16gb and d820/d821.
