Lost network connectivity and phone signal

I am on ecliptic rez v7. I just had this problem today where all of a sudden, I had no network connectivity and no phone signal at all. I had not messed with anything network wise for my phone. I tried restarting my phone, clearing cache and dalvik cache, turning the phone completely off and on, but nothing. I couldnt even get the option for network modes on my phone, it just had limited signal for emergency calls.
I ended up reflashing the same rom and its working back to normal, but I was wondering what could have possiblly caused this. I had this happen only 1 other time to my phone randomly, but it was on counterstrikes CM9 rom.
Has anyone had this happen to their phone?

MROM-Olympus Issues

Hello guys, I would have posted this directly to the MROM thread but I can't due to not having 10 posts....so I'm posting here and hoping somebody can help me or draw attention from someone in that thread that is running this rom. I'm having a few issues with this ROM that are leaving me unable to use my phone at times and others that are just annoying.
[ROM] MROM-Olympus [CM7] build:20130330
Problems with the Phone function:
1. The biggest problem for me is sometimes trying to dial or receive calls stops working, and you don't know this, when everything else on the phone is functioning fine. A reboot will allow the phone to be able to dial out and receive calls once again. I have not noticed any patterns ...just when I get ready to make a phone call it says "dialing" and then after a few seconds a beep and it hangs up. Also as noted when this happens I'm unable to receive calls and everyone gets my voice mail. It was doing this after a install and without anything else being installed...I do feel that it's gotten worse as in happening more often but that could just be my frustration making it seem that way.
2. Another phone issue since day one: Sometimes after dialing a number the screen goes off and pressing the power button may or may not bring the screen back on or if it does the screen comes on for a split second then goes back off. It's impossible to end a call this way or to enable speaker phone, look up contacts. When it's functioning correctly a call is made then the screen goes off when i place the phone close to my ear and comes back on when i take it away. A reboot fixes this issue usually for awhile, I've also had to take the battery out twice because the power button did nothing.
Problems with the wifi tethering function:
3. Wifi tethering works but I've noticed problems on upstream packets. On 4G the phone can hit 5-6 Mbps down and 1.5 Mbps up on T-mobile. I've ran test via "speedtest dot net" which they have an android app so you can test your data speed right from the phone. Now when I connect "wifi tether" my computer to it and run the test from the computer I get the 5-6 Mbps down but the upload test takes forever to start and when it does I usually get anything from 25-220 Kbps. I performed this from linux, windows and an android tablet ..all report slow upload speeds while the phone directly running the same tests get very good performance. I'm wondering if this could be a issue with the wifi driver or possible kernel issue of sorts.
I choose this rom because from what I read it was one of the most stable and everything on the phone works which is the most important thing to me.
Thanks in advance!
Happened again today, phone uptime was 17hrs. I'd made a few phone calls and received one, pulled the phone out of my pocket to make another latter and it did it's thing where it says dialing .....a few seconds then the beep like when you hangup and then back to the contacts. I checked this time the status and it showed in service and data connected. I was also able to txt and browse the internet just not make or receive calls until a reboot.

Network drops when making or receiving calls

Hey guys. So I've been trying to figure this out for several weeks with no luck and I was hoping you could help me. I have a Verizon LG G3 on AT&T on 10b. I can connect to 4G LTE and Edge just fine. However, when I try to make a call or receive a call on LTE, the network vanishes instantly. I'm talking from 3-5 bars to no service in within 5 seconds of calling my phone or calling from it. I've tried flashing different modems and the problem still persists. I already tried flashing the stock (what I'm on now), factory resetting, clearing the cache, etc. and have not been able to fix it. Today I called AT&T tech support and after they re-registered my phone I was able to make one phone call before the problem reappeared. When I made the call, my LTE dropped but I stayed connected through 2G/3G/Edge not sure which one.
The only other time I've had it working properly is when I had Cyanogenmod installed. However, that led to another issue. With Cyanogenmod, my phone would crash within a few minutes of booting. Most of the time I couldn't even make it through the setup. To be more specific about the crash, my screen would freeze and become unresponsive for a dew seconds and would then turn off completely. The green LED would turn on and stay on. Every time this happened I would have to pull my battery. The only way to prevent the freezing was to turn on airplane mode. If I turned off data or had the phone SIM-less it would still freeze airplane mode was the only solution.
If anyone can help me with either of these issues I would be greatly appreciative. If you need any more information or want me to post logs just let me know and I'll happily do so.
Here's a quick recap incase you don't want to read through the walls of text.

EDGE works fine
On 4G LTE network disconnects when making or recieving call
Cyanogenmod fixes network issues but freezes when not in airplane mode

I think you are talking about making calls on Voice over LTE. I am not surprised Verizon rom does not quite support it. Maybe you can try this swap boot.img hack to install AT&T rom and see if it solves your problem?

Thanks for replying. That's my main theory too. However, according to my research, the VS985 didn't get VoLTE until the 12b update. I'll definitely try an AT&T ROM when I get the chance at the very least I'll probably learn something from it. Any chance there's an option to make LTE data only on this phone?

Calls Getting Delayed

After i try to place the second call; it gets delayed for like 10 seconds. in that 10 second time period, the phone runs other programs normally . and suddenly it starts calling..
This gets very annoying . I reseted and reinstalled the system via Companion tool its still the same..
Anyone experiencing this issue and any ideas how to fix?
* I was using Truecaller and other calling related programs. Uninstalled and still the same.
* Using 6.0.1
Kind regards,
wifi reception and this issue is now fixed in the latest build. (.575)

Wifi/Bluetooth randomly failing Huawei y6 2017?

First of all I know it's a crap phone.
It is not my wifi that is the problem, it happens on all wifi networks.
I didn't drop the phone or anything like that.
I am running stock Android 6.0 (no root)
I previously used a hack from this website that involved putting code through MinimalADB to mount an sd card as the main storage as this phone doesn't support apps on sd card (Did after that hack!).
On my phone randomly when I am using my wifi the wifi stops working randomly. There is no warning and no sign except only the left arrow beside the wifi bars lights up (the bars are still full). Nothing at all will load. The only solution I have found to this problem is restarting my phone. As this happens usually after 10/15 minutes of using the phone it is beyond irritating. The Bluetooth also goes and even though it says I am still connected to my headphones no sound will transmit. Mobile data still works.
If anyone can help it will be super helpful.
