[Q] E980 loses signal when calling at home - LG Optimus G Pro

My E980 has a real problem making calls in my house. I have great signal and can use data without any problem, but if I try to make a call I go from 4G LTE and 4-5 bars to nada. If I am lucky I will get one or two bars back before the call times out and actually get to connect; otherwise the call times out and if I try again it tells me I can only make emergency calls. I have to either reboot or go into airplane mode and back to get it to try again. No other phone on the same network (AT&T) has this issue, however, and my SIM works just fine in other phones (does not have this problem).
I am running stock 4.4.2, software version E98020h. I am rooted and have Xposed installed with the G2 Tweakbox.
I've done multiple searches and did not find anything that pertains to my issue.
If flashing is required I am not sure if that is possible as I cannot access my SD card (KitKat issue and no app has helped).

Or maybe not. Time to find a decent ROM then.

No signal, T-mobile, WCDMA

So i rooted my phone over a week ago, and tried out many different roms. Everything was going fine, until i noticed yesterday that i kept losing voice and data connection. I tried updating to the latest radio which was out today 5.09.00.20, but still have the issue.
The only workaround i've found so far is to set the network mode to GSM only. But obviously it's not very practical for a phone like the desire. When i have it on GSM/WCDMA Auto, it keeps voice and data on for about a minute, then i lose it. And when it's on, i still can't make any calls. But i can make and receive calls fine on GSM only.
Anybody have a clue what's going on here? I tried calling T-Mobile, but they were as useless as always. Apparently there was an issue on the 29th, which is now resolved, and they refreshed something on my profile. So i dunno if rooting/flashing my Desire has caused this or if it's some network outage.
I'm currently running the latest DeFrost rom. I've tried SenseFroyo (Opendesire), LeeDroid & i'm now running the official 2.2 sense rom.
I've also been having problems when connected via 3G for the past few days, but only when I'm at home (so I think it's a specific cell). The signal indicator shows a good signal but attempting to use the internet over 3G just times out, and my voice calls keep getting dropped.
Like you I can work around the problems by switching to GSM only.
I think it might not be a problem with my phone though, because I've tried putting my SIM card in my Nokia N95 and the internet doesn't work over 3G on that either (internet works using GSM on N95). I did manage to make a call on my N95 when my Desire was dropping both incoming and outgoing calls within seconds though.
Weird! I'm going to give it a few days and report it to T-Mobile if it's still happening.
It's fixed for me now. I guess it was a network outage

A few questions about the GNex - Network, Mail etc.,

Hi Guys,
So, I've been using the GNex for about a month. I moved to this phone from a Moto Atrix and here is what I have noticed and have looked around but didn't see any good answers to these questions I am having. Hopefully I get some answers here.
Device info:
GNex GSM version on ATT.
Running JB 4.1.1 Stock with Trinity Kernel (rooted and bootloader unlocked).
Issue #1: I get really bad reception at work. But, when I leave the building, my phone doesn't automaticaly connect back to the network. Sometimes, if I don't check my phone, it's been like that all night long until the next day when I have tried to make a call and it said "No Network Available" and I have to either reboot or toggle airplane mode to get back on the network. Am I missing something? In my past experience with other devices, they try to automatically connect back to the network when they loose connectivity. Also, if I get in an elevator during a call and the call gets dropped due to network unavailability, it doesn't connect back to the network and I have to toggle airplane mode. Has anyone else had this issue?
Issue#2: This is with the stock mail app. Specifically the search in this mail app. No matter what, it always returns zero results. Has anyone had this issue with the Mail App? If I use the Gmail app, it works fine. That's what I am using now, but am curious as to what I may be missing that make it not return any search results in the stock mail app.
Q3: Speed Dial: How do you set speed dial on the dialer? Is it even supported?
thanks in advance,
vG

it could be to do with your radio, what version is it? baseband version in about phone. im no expert but when i flashed a jellybean rom i had to update my radio afterwards cause my signal was dropping alot. i also had the same problem later on but that was down to my network operator. before i realised it was them i googled my problem and a few forums suggested that my sim card was goosed. so maybe check those three possibilities? i cant help with the other two issues unfortunately but good luck sorting it out!

[Q] Help with understanding logcat (dropping calls)

I have a strange issue with my HOX and i wonder if anyone can read something about that from my log. I've been having call dropping issue for a while now (seems to be on aosp only... sense roms work great). If i start a call and have data enabled I sometimes get an issue with signal dropping (No service). I never have that issue with data disabled. If i'm connected to a wifi network i don't have that issue. The issue is only there if I have data enabled and not connected to wifi network (either wifi off or out of range). I've been tring to understand what the problem is but I've had no luck (been searching for a solution for about a week... tried different settings... like "wcdma only" but the problem is still there)
The problem doesn't always arise but still pretty often... It happens often on some roms and not very often on other roms (I've only had this issue twice on cm11 but get it almost every other call on SlimKat). I've attached a logcat from SlimKat while outgoing call dropps signal. Hope any of you can shed a light on my issue. I looks like a hardware problem but i don't understand why it works on sense roms.
Edit: I first had this issue after I OTA'd to 4.18.401.2 (with new hboot 1.72). It's a shame HTC denies us s-off. Otherwise i would just go back to hboot 1.39 but i'm hoping i can somehow fix this because I really love AOSP roms and i really don't like Sense.
Edit2: This only happens on outgoing calls. Never on incoming calls.
Edit3:Took out the sim card. Polished it a bit. Put sim card back. Now in 10 test calls i never had signal dropping. I cut the sim card myself and now i guess it's time to go and get a proper microsim.
Edit4:Still had a signal drop on outgoing call.
Will report back after i get a new sim...
I tested the HOX with another sim card from another carrier. No problems whatsoever. I tried my sim card in an iPhone 4 and it worked without any issues. As soon as I put my sim card back in my hox and place a call I get "out of service" (with data active and wifi disabled). I just don't understand. Everything works great with data off or if I'm connected to a wifi. I really don't want to change my carrier (it's just so cheap )
BTW the sim card is not very old. Maybe a year max (although i did cut it to size myself but I've done that dozens of times for myself and my friends and have had no issues)
Anybody got any ideas? (haven't tested with different sim card from my carrier.. will test as soon i get a chance)

H812 Keeps Losing Signal (Please Help)

Hello everyone, I've been lurking here all weekend as I've been trying to stabalize this phone I bought off of Kijiji. Right off the bat, when I
installed the sim I forgot to turn off the phone . Haha, I was extremely tired & only when I removed the battery (of course) did I realize what
had happened. Ever since the sim has been in, the signal has been unstable every 5-10-15 to 30 minutes (this is without running POGO). By
unstable, I mean both data & most importantly calls. I won't be able to make or receive, when I place the call during these failures it will
say dialing, connecting... and just continue until "call ended". And when I"m called, outside of LTE just say we've forwarded your call to VM. On
LTE, it will say something along the lines of this customer isn't able to receive your call at the moment.
Troubleshooting Attempts:
- Tried SIM in a different phone & it worked perfectly
- Power Cycled Several times, Factory reset it 3 times
- Set up 2 APN's (sorry can't link yet, but google them if u like they're ez to find. LG G4 VM Canada APN's)
- ^ Tried both, both unstable, but PDA gives most stability
- I've registered to all available networks under GSM/HSPA/LTE all unstable
- Connected Automatically & Manually to GSM/HSPA/LTE together & separately. All unstable
- Phone is not in Air Plane mode
Model: LGH812
Unlocked, Original Carrier: Rogers
Current Carrier: Virgin Mobile (Canada)
Android OS: Marshmallow
Kernal Version: 3.10.84
Build Number: MRA58K
Software Version: H81220x
Now, I have just recently come across a very interesting development. Using the App Network Signal Refresh Lite,
In pokemon go I've been able to transition to a signal that will stay solid for up to 5 minutes, 3 on average. It will still
lose connection, but will usually reconnect in-app in moments. I do have to minimize it & do a refresh again in NSRL
every now and then but it's a big improvement. Before hand, when I would use go, the service (calls included) would
completely rip in seconds.
So... any ideas? I'll appreciate any & all help.
I've flashed every stock rom I can for the device too, but the signal continues to drop regardless of the OS. Some error messages I' ve gotten are emergency calls only, no service & service disabled but usually it just shows that its connected to virgin but I can't make or receive calls.
Other than the cellular service, everything else with the phone works perfectly. The wifi, the camera, the gps, etc it would be a shame to have to get rid of it but the essentials first. I have to be able to make calls.
Please, anyone, any ideas? Are there any apps I can install to fix the broadband or something.
It won't remain stable no matter what I do... and no one has any solutions
tips, thoughts or ideas? Really regretting this purchase now... It's been a
month and I still cannot get a stable connection. This is ridiculous.

You may want to check out this link (https://lg-firmwares.com/lg-h812-firmwares/) for an H81220X Bell/Virgin kdz (H81220x_00_1122.kdz) and use LGUP-NEW to install it. It might help but if not, you may be facing a hardware issue ...
Solved lg g4 losing signal
I bought my lg g4 K450 and within days l noticed my phone was losing signal constantly. By the grace of God l tried this and it worked.
Go to settings---Then to Network---To more---To Mobile networks----To network operators. Select search network. All available networks will be displayed after a thorough scan. Select your network provider with a WCDMA instead of GSM and it will register it. After it done registering, restart the phone. and u are good to go. It worked for me, if it works for u give glory to God.

No Internet Connectivity on my HTC 10 - Please help..

So I got this phone from my Grandpa who recently passed. I was able to insert my AT&T SIM, reboot, and use the phone as normal on 4G+ without any issues what so ever.
Fast foward 24 hours and after rebooting my phone a couple of times and accidentally "Updating Profile" my 3G/4G no longer wants to connect. What's strange is Voice and Text still work as long as the text isn't a MMS since that server is also no longer connecting.
I have confirmed the radio is functioning as I can switch it off, verify it's receiving signal from the nearest WCDMA tower through the 4636 menu.
As well as airplane mode and wifi are working
Sometimes my wifi will not connect first-time unless I "forget this network" and use WPS button on Router to connect - it's like my phone won't authenticate the network once a password is entered. Once connected it stays connected without issue.
Some things I have tried already:
I have attempted to change APN settings to strictly AT&Ts 3G connection - no luck.
I've installed custom ROM, Recovery (Bad Boyz HTC 10 Oreo Stock ROM, TWRP) - no luck.
I've reinstalled stock firmware from HTC RUU - no luck.
Got a new SIM from AT&T and had a tech "diagnose" my phone - no luck.
I've searched all over the internet and found multiple threads about having no signal or no IMEI, but this doesn't completely fit my issue as you can see in my pictures I still have a valid IMEI and cell signal. AT&T said everything is fine on their end regarding my phone, but since it is not an AT&T phone any other support I'm going to have to find elsewhere (Screw AT&T)
The only other thing I can think to try is purchasing a Sunshine license to S-OFF and try manually deleting the radio partitions and then reflashing an older radio or stock radio, but I'd rather not spend $25 for this solution to not work or further complicate my matters.
My question is has anyone experienced this random loss of 4G connection but still have the ability to call and text on their HTC 10? I know this is an older phone, but I really like this phone after using my LG V20 for so long.
UPDATE: Put the SIM in my LG V20 that I was using prior to switching to this device and it is also now having the same issues.... Wtf is going on?
Thanks for any responses!

At your own risk, this:
In the bootloader enter these commands:
fastboot erase modemst1
fastboot erase modemst2
(this will wipe the faulty modem partitions we are about to reset)
