Hi,
I have a problem with mobile network connection on every AOSP roms that I flash. I have been using my phone with Pixel Experience Q with no problems for few months but few days ago I decided to install MIUI 12 to check it.
After flash I saw that it's not for me so I flashed PE again. I didn't do any backup because I wanted an clean flash and didn't expect such an issues.
On PE (and every custom rom that I tried) wifi works flawlessly but mobile data shows LTE+ connection in quick tiles, but nothing that uses Internet connection works. Calls and messaging work and phone is fully usable except cellular data.
I tried apn settings, EFS reset, DNS changing and few hours of searching I have nothing.
Has anyone had similar issue?
EDIT: I found a solution. Recently I had enough time for my phone and tried again. Here's what I did:
1. Flashed MIUI 12
2. Turned phone on once
3. Flashed OrangeFox Recovery
4. Backed up everything except internal storage
5. Installed PE using standard method (recovery + format data)
6. Restored modem, EFS and persist
7. Changed APN to IPv6
That's everything. Separately nothing worked for me but when I did every step my data connection was back.

Hi there,
Since I bought GS+ few weeks ago with 2.3.3. (xx??? rom) in Latvia, I have tried several ROMs and always rooted after that from recovery mode by flashing Root.zip.
There was a problem with my def rom, about 80% of sms failed on first send, so i gave it a try for other roms.
Right now I am using rooted XXKP4 (2.3.4.) as I found it the most stable for me - no WiFi issues, but every 2nd sms still fails.
So far I tried asian SZKP6 (2.3.6), european XXKPJ (2.3.5.), XXKPG (2.3.5.), XXKPS (2.3.?). Always the same - they work fine, no sms problem on any of them above 2.3.5 (including), but always there are problems with WiFi - it drops signal and changes connection to 3G/2G. Sometimes it drops every 5-6 minutes, sometimes it drops once in a half hour.
I always wiped data before flashing and did factory reset after flashing with Odin, after that I always root it with mentioned method and restore all my apps/system data with Titanium Backup PRO.
Could you guys help me find out what is the problem?
I want to get fully working 2.3.5 or 2.3.6, without any issues, but right now I am stock with 2.3.4 because I prefer push resend my messages better than Skype video call dropouts because of auto changing internet connection type.
Thanks in advance.
the only thing i can say is had the same issues with wifi dropping and first sms of the day would faili tried all the roms including the one im using now and they all had the wifi faults UNTIL i did a full factory default and erased disk, now im using the XXKPS 2.3.6 and it works fine.
So make sure you do a fresh start after flashing your Rom.

Factory reset after flashing with this code: : *2767*3855#
Backup first your internal sdcard because the reset will erase it.
I'm also on 2.3.6 KPS and think I have no wifi drops.
And to think I mean, I have not noticed.

Just a question - if I backup my internal sdcard before flashing and full reset with code listed above in previous reply, can I restore (copy from PC) all my files after everything is done?

The same...
Tried two roms (2.3.6 and 2.3.5) which works fine for lot of people here in xda-devs.
Factory reset before, and another reset after flashing, but the same situation. Everything works fine except WiFi - when I open WiFi settings, it shows refresh (search) every 5 seconds and drops after some minutes.
I'm on KPS and havent noticed any wifi drop.
How often does it drop? Does the wifi icon disappear when it drops and reappears when it connects?
i must of just got lucky, all i did after flashing to XXKPS was a complete reboot to factory defaults from settings/privacy/factory data reset and wiped SDcard aswell when asked, i then installed all settings and apps from scratch i didnt use any previous backups.
like i said before i installed XXKPS and got wifi drop outs but this is the rom im using now and the wifi is fine now, the only thing i did diffrently was what i wrote above.

Jep, this is how it happens - WiFi icon disappears and if connection is active, it drops (interupts d/load, skypoe, etc)
BackDaws - i can notice it before rooting and restoring my apps/sets. Last time I tried xxkps, it dropped for first time before I managed to copy root files to my sdcard, so this is not about restoring.
then just keep flashing it until you get the wifi working, im scared to flash to anything else now as that wifi bug was getting on my nerves.
are you using a Belkin Router by anychance ? ive read that changing the DHCP lease to 2 days instead of forever resolves this problem.
Try it
I'm kind of worried at this point. After looking through some threads I found with a search for a similar problem I'm going to make my own.
Problem: No data at all. About section of phone says:
Network: Unknown
Mobile network type: Unknown
Service state: Out of service
Mobile network state: disconnected
I do still have an IMEI.
It happened in the middle of normal operation, browsing the web with stock browser with CM10.1 (4.2) with the 1/20 nightly.
What I've tried: Already reset SIM card, toggled Mobile Data and everything data related I can find in the Settings menu. I've data wiped and flashed the same nightly through recovery along with the same gapps .zip that was all working halfway through the day. I got home from work and tried using Odin to flash back to a pre-rooted full wipe 4.1.1 ROM found using this thread: http://forum.xda-developers.com/showthread.php?t=1984436
The first time it booted up to the stock startup screen and just hung. Cleared data through recovery, booted into Odin and tried again and it booted up, but still no data. That's where I am now. I just don't know what else to try. I see some stock radio flash instructions but I'm really not sure what that accomplishes if I'm already flashing stock ROMs. The trouble is I know just enough about this to break stuff.
Does anyone have any recommendations or ideas?

SOLUTION: Settings > Mobile Network > Network Mode - was set to GSM/UMTS in 4.1.1 pre-rooted ROM. changed to LTE/CDMA and resolved. Can't believe I overlooked that.
Thanks.
So a week ago I did a fresh install of Lollipop via the factory image for LRX21O, rooted it, and installed Franco's kernel #68. Everything worked great until yesterday as it seems I've lost all mobile data connectivity. I can still make phone calls and text messages, but data is a no go when mobile. So far here's what I tried:
Made sure the APN was Correct
Cycled Flight Mode
Cycled Power
Pulled & Re-Installed SIM Card
Cleared the Cache
Factory Reset
Re-flashed Stock Kernel
Flashed Android 4.4.4 Radio
Re-Flashed Lollipop Factory Image
Restored Previous known working install of Android 4.4.4 via TWRP
Made sure there were no billing issues with my carrier.
Anyone have any ideas? I'm especially concerned and convinced its not specifically a Lollipop problem (though that doesn't mean it didn't cause it) since it did not restore functionality when I flashed back KitKat. I've never used 3rd Party ROMs on this phone, only rooted stock. My carrier is SimpleMobile.

Maybe you need to contact your carrier?
You're not alone, I'm having the same problem since going to 5.0. I use Red Pocket on AT&T's network. Can't get mobile data working at all. Contacted Red Pocket and they reset my data on their end but still a no-go. Wi-Fi fine, calls and SMS fine. MMS, like data, doesn't work.
I guess I'll pick up another MVNO card to make sure it isn't still Red Pocket's issue. I have another SIM, but unfortunately my T-Mobile card, which is usually in a Lumia 1520, doesn't work for data on the Nexus 5 because that is on their blocked list of phones (stupid carriers).
I've been having a problem recently where even though both wifi and mobile data say they are connected, I can't acutally get online. I see an error v30 toast pop up regarding voicemail (if that's related) and when I try to use a browser, it doesn't load the page and gives me a dns error message.
This happens across rooms (after clean installs, every time) and even after wiping dalvik, cache, data, system, and internal multiple times in TWRP and doing a data format on internal multiple times, then flashing stock ok4 in Odin. Still no data. I then hunted down the ok4 modem and flashed that through Odin - nothing. So not even going back to stock (at least the way I'm doing it) fixes it.
The only thing that works is that I have a nandroid backup of the stock, rooted, deodexed ok4 rom with the kt kernel, which can connect via wifi and/or mobile data. If I want data though, I'm stuck on this rom. (When mobile data is turned off on this rom, there's an exclamation point by the network signal. Not sure if that's related.)
(If it's related, I've also been getting an invalid card error instead of seeing the carrier name on asop roms.)
Anyone know how to repair this?
Sorry if this was addressed elsewhere, but after searching for a while, I couldn't find anyone with this type of problem.
I was originally going to use a custom Rom Havoc specifically. I am using the global unlocked model. After flashing stock rom using recovery tool and the flash all bat in the zip file everything is working on the phone except cell service The phone recognizes the verizon sim card itself but I have no data or signal. I tried using older 9.5.3 and 9.5.10 versions and it has made no difference. Factory reset has been tried as well and I still have no data. This is a big deal for me as my gmail account I use for my phone uses two step authentication. Is there anything I can do here or something involving needing to get TWRP back on my phone to resolve? Any help will be appreciated as I've spent last 2 hours trying to fix with no solution
It's also picking up my phone number and the information via sim card, but when I try to run a call/ send a text I'm greeted with a message that says To make a call turn off AIrplane mode. (Verified airplane mode is not on)
I"m not sure which thing I did that fixed it, but I flashed modem.img and also went to recovery and did a settings wipe not a full factory reset but just for the settings and it seemed to fix it
