[Q] Phone cannot connect to Mobile Network (CM 10.2)

Hello, I had successfully flashed my LG G2 (D802) from stock to CM 10.2. The sim card was recognised and joined immediately to EE (UK - Mobile Network *T-Mobile/Orange*). During Christmas I tried flashing a new nightly from Cyanogen Mod (11), however I had an outdated clockworkmod version (even though I couldn't update it further). I couldn't launch back to CM 10.2, as the data was wiped when trying to flash CM 11 (Nightly).
Due to not having a back up file, I reverted to factory settings first, then wipe 'all' data off my phone using ALL the options avaliable on CWM. I then had to use 'adb' to push CM 10.2 back into to the phone. It successfully flashed and it was running stably. During the set up pages, CM gave me a pop up to look at sim card instructions to 'get it working', i thought this was a minor problem and couldn't to set it up. When this was finished, gave me everything (WI-FI, bluetooth etc.), however I didn't connect to my Mobile Network 'EE'.
I set 'Data Enabled', Network Mode: WCDMA Preferred.
I tried automatically/manually connecting via the CM settings, but response was 'Could not connect to this network. Please try again later.'
So no luck so far in connecting the phone function back up.
I would be truly thankful if everyone could help with a solution. ^_^
Many Thanks!

I've found out that the phone is locked to a HK network, but I am currently studying in the UK. The problem is that I can't unlock the phone in the UK with using the HK network; I have a HK sim card as well as UK, but since the phone is locked I can't use a UK sim card and the HK sim card doesn't seems to register UK Networks.
Anyone got suggestions to bypass this?

[Q] Upgraded to Android 5.0, Lost LTE

I just upgraded to Lollipop and lost LTE. I have EHRPD 3G only.
I am rooted and on Extreme Syndicate 5.0 Lollipop.
I have tried the usual items found in Google:
1) Removed SIM, rebooted. Put back SIM
2) Checked LTE settings under mobile networks (Global, also tried CDMA/ LTE)
3) Checked APN (vzwinternet, internet and VZWINTERNET)
4) Tried basic toggling of airplane mode, data, etc.
I am trying to avoid going back to kitkat stock and working back to lollipop.
I am hearing that a new SIM may be required but I have not gone that route yet and would like to resolve right away rather than taking a day for a SIM to ship to me.
Any help is appreciated.

Have you factory reset the phone after the update? It would be something to try.

I tried numerous things. Right now my LTE has come back however things are kind of strange when I reboot, but at least ultimately end up working. I have a new SIM to throw in there when I lose things entirely again. I'm now sort of convinced that the problem is the SIM as I have tried a few different ROM's including stock unrooted KitKat and data always acts the same. I'm now on 5.0 and it's again the same.

Hello, after upgrade to 5.0 my s5 verizon, i lost 4g, but on 4.4 it worked fine in russia

sprint S4 network not working

Hello everyone!
I've got my Sprint s4, unlocked it to use in Canada and flahed JFLTE-GPE. Since then i had no problems for half a year, but this autumnthe ROM got an update. It has lost all the personalisation and other stuff and moreover started rebooting randomly. I decided to switch to OCT-L, and the phone couldn't connect to the network. I tryed different settings and it either was written "Sprint" or "International" (at the network status). But also there was a setting at which it was rapidly changing from "Sprint" to my SIM card network. I flashed JFLTE-GPE back, but nothing changed except it didn't connect to my SIM card at all. I flashed OH1 modem (saw it somewhere on the forum) but it didnt give anything.
Help me anyone please!:crying:

Can't get LTE on G900-R4

Hey guys, hopefully you can help me get my S5 back on track.
KLTEUSC G900R4
The story goes:
I've been running CM13. Flashed a nightly, I notice my phone hasn't locked 4G basically all day. 3G only.
So I Odin back to stock using the latest firmware. Phone is still stuck in 3G. Phone does an OTA update to CPF2 baseband version. Still no 4G.
Took the phone to USC store, they provided me with a new SIM. Nothing changed.
I took a trip out of my home area, about 100 miles away I got 4G, but i had no network connection? The phone displayed 4G but i could not connect to any internet. It then dropped down to 3G shortly after and I was able to access data again.
Since then I've flashed back to CM13 (snapshot august 20th release) since if I'm going to be stuck in 3G forever, it might as well be on a ROM that I like.
Please help!
Thanks,
Jeremy.

Bump. Still no LTE.
If I reboot the device, the phone locks LTE for a few seconds, with network connectivity, but then quickly loses it and drops back to 3G. If I leave the phone in LTE preferred, it will run in 3G for most of the time, but occasionally totally lose data (I'm assuming its trying to connect to LTE) then go back to 3G.
Any Ideas?

flash the stock tar.md5 in Odin, reflash TWRP, boot it up fully, boot into recovery, make a NAND, reflash your ROM. Sounds like something got screwed up in the radio firmware

Will that still work even though I can't get 4G when i'm on the stock rom?

$50 reward to whoever can successfully restore 4G LTE to my phone. I've been living on 3G for 6 months and its starting to get to me.
I've been on Lineage OS with the same results. There was a firmware update, so I flashed it through Odin, and ran the stock rom/firmware for about 3 days with the same results. No 4G. Called up the US Cell Tech guys and they were going to check everything over on their end.
The last go round, I repartitioned the phone, did NandEraseAll, and EFS clear.
Any ideas?

Verizon had it working, but now on replacement axon7, no more VOLTE

Hi, I'm hoping someone else on verizon can help me here.
I am on TW (mvno) but verizon works the same, i just dont get all the towers as a full verizon customer does.
Anyway here is my setup. I have a axon 7 running RR 6.0.0-20180511, hellsgate 3.18.109, ver 2.3 & baseband TH.2.0.c1.9-. I think I have B12 bootstack but I'm not sure about that. VOLTE works great on this my org axon 7.
Now replacement came in cuz I have the screen goes half gray issue. Here is the problem. I loaded up my current setup via twrp nfound 3.2.1-7 and everything works its exactly duplicated in every way except for the change I made to go to f2fs on data and cache. I also tried a different bootstack B10-B32 same results so its not related to bootstack or modem as that is the same.
What is really odd is I can pull the sim tray and the option for "enhanced 4g LTE mode" shows up, I put the sim back in and it disappears. My thinking on this is its something to do with the phone trying to confirm my sim capabilities and not being able to. I went over to testing mode and I can try a million times to turn on VoLTE with no change at all after multiple reboots. I also tried sim swaps with old none active tmobile sims and a partially active at&t sim. This did about the same as the sim tray pull out & allowed me to see enhanced 4g LTE mode for as long as that sim was in place and as soon as I swap back to my sim it disappears.
So what is the issue? Could it be the sim & IMEI? Or is it just something on the phone (hidden trigger) that I need to change over. As I said I had this all working, on my org axon 7 with same rom, kernel, bootstack and modem. SO what gives?

I had this same issue. When you got your new phone, did you call Verizon and have them add your IMEI to their database? That's what did the trick for me.
