OptimizedCM January 18 not working with FreedomPop

So I've been running with OptimizedCM-12.1-20151130-jflte on my FreedomPop phone, and it's been working OK. Got an OTA (20160118) update and installed it, and while I can apparently get onto the data network, FreedomPop Setup is forever spinning its wheel "Registering for push notifications". It's an L720, of course.
So I can browse the web, but I can't use it as a telephone.
Fortunately this isn't my main phone, so no panic.
n.b. dirty update.
p.s. Pretty sure I'm not a robot, but I could be a cyborg.

I was mistaken, it's not getting data either.

Never mind, a clean install worked.

Nexus 6p calling issues, please help

Hello,
I have an international version Nexus 6p. While I was in Panama I accidentally removed the OS using TWRP, after rooting. I reinstalled the latest OS, TWRP, root, and used a custom ROM. I was dumb and didn't back anything up.
I couldn't make phone calls or access the internet with my phone on the network I used there, but I could with WiFi so I chalked it up to the ROM. Removed that and did a fastboot factory reset. I still couldn't make phone calls or receive them so I figured it was the network in Panama.
When I got home I still can't make or receive phone calls. I can text, and access the net but the service is very unstable. I am using cricket wireless, and I know it's not the service because the Sim was in my gf's iPhone and worked perfectly, and my friend has cricket and his is stable and works perfectly. I am running the latest Android 7.1.2 and would love some help with this issue.
I have tried flashing a new factory image, erasing modemst1 and 2 through fastboot, changing bands, using a different Sim card, factory resetting in general.
I have not tried another ROM (read somewhere that chroma would fix the issue, but don't really wanna jump back to 6.0.1 unless I have to).
Thanks for any help.

i-9505G, Correct APN but no data

Hello folks,
Galaxy S4, Play Edition, currently rooted and AOSP 7.1.2 installed.
I rarely used data on this phone and never since I installed the ROM. Lately, I needed the data often and I noticed that I do not get the data on this ROM. I confirmed with the carrier about the APN settings (Airvoice Wireless, att MVNO). The carrier reset data from their end. I tried manual APN entry but none worked.
Searching on the web led to various ideas, like reset network settings, airplane mode on/off etc etc. Tried everything, no change in the status quo. I am at loss on what is the problem. I tried the SIM in my wife's phone (HTC One X, Kitkat) and it worked without any issue.
I could not figure out PDA, CSS but the baseband version is I9505GUEUDNL3, in case if it needs an update.
I checked the thread (https://forum.xda-developers.com/galaxy-s4/general/ref-galaxy-s4-i9505-modems-bootloaders-t3315987) over and over but didn't understand what/how this stuff is worked out.
I am really going nuts and I do not want to pony up for a new phone at this moment.
Any help is appreciated.

Flash back to a stock ROM and check for data connectivity. If everything works, it's a ROM issue rather than being a hardware issue.

The issue seems to be related to the ROM.
I restored to 5.0 (LRX21P.S012.141205) and the data works flawlessly.

I lost the signal on my cell phone after moving from Android 9 to 8

hello, for my curiosity use the method with vpn to update my cell phone to Android 9, apparently everything was fine until I realized that I did not recognize the 3g, something that made me very uncomfortable so I down to 8.0, my surprise was when now instead of agrariar 4g already not even took signal, with luck it recognized the SIM card but it did not allow to use Internet Mobil nor to make calls, also at the moment of updating it to 8.1 this simply froze in the logo of Android one, since I did not have a backup, I tried to put a ROM that I had previously used and that if I grabbed 4G but now nothing, for me it is more important to have a signal again, please help me

What Rom did you use?
The last one from Miui.com?
I think that you must reflash Android Pie

Just do this
Go to settings. Applications then clear data for Google play services,Google frame work, location then remove the sim card and use VPN switch to Netherlands or us and use wifi till the update is done you won't get any problems

Looks like corrupted IMEI to me. Just search, I saw a thread with guide to recover IMEI when downgrade from Pie to Oreo.

phone says there's LTE service, but disconnects when making a call and cannot receive/send texts

I installed the latest lineageOS 19 version, rooted my phone then ran into this problem where the phone says i have service, but when i place a call it wont fully make the call. Then my mobile data will X out and i get pop up error saying mobile service is unavailable. I then tried lineageOS 18.1 and arrowOS and same problem persists.
formating between installs obviously.
I have looked at every option on this phone and tried combinations and everything in the network/system/ everything and still not working.
The process was actually very simple since i have some programming experience. Other sources mention possible baseband issues? On the fastboot screen it shows a baseband version. all the information there appears normal. I only flashed the boot image one time to root and didn't mess with any other manual flashing processes. Just used twrp. I didn't quite understand twrp at first and therefore didn't get a backup using it... iused adb to make a backup which apparently didn't work so Im lost and hope someone could help me out here. please and thank you!

If i may add I can use mobile data just fine, i can browse the internet and such (with wifi off and data on only) so i really dont understand. Is this a normal issue to have when using custom roms? did I trip some security that blocked me now? any input???
I wonder, though, this moto g7 is an A/B partition thing. so if i understand correctly, flashing twrp would not work and thus why i did not do that. it makes sense. But should i try flashing it, booting into it then installing lineage? even if i did i feel like that would give me same issue considering the method i followed got me into lineageos, plus root checker said i was rooted.

What I can tell you is what I had to do in order to get LTE (voice calls) running on my G7 - I was forced to switch over to LTE because AT&T turned off 3G here in the US and 4G without LTE is not good enough for voice calls:
Get the latest stock firmware and install it using e.g. Lenovo's "Rescue And Smart Assistant". That will get Motorola's Android 10 on the phone.
After installation, go through setup and actually make a call (calling your mailbox is fine). Then check your ims status (*#*#4636#*#*, goto phone info, pull ims status) to see that ims is actually working.
Shutdown the phone and start installing LOS (use the partition copy script too to make sure that the partitions not touched by LOS installation are updated "on the other flash bank").
Go through LOS setup, select a valid APN for your setup, set "LTE only" or "LTE / WCDMA" for the network and make a call. You should be good to go.
Again this is what I had to do to get LTE working with AT&T USA. YMMW.

I know this is way late, and you probably already figured it out. I didn't share the no text problem. The Problem isn't just the "LTE" setting itself. There is one more option(some Roms show it, some don't) I believe its in the phone app settings? VOLTE must be checked. I have noticed Some Roms do have this option and some don't. when volte is checked, it'll keep your data/internet on during a call, some Roms that option won't show up or isn't available. I haven't used G7 in a while, but I do remember the problem and how to fix (on my phone anyway).
