[CM12.1][5.1.1][D618/D620] Unstable Data - LG G2 Mini

Hi,
I installed CM12.1 rom (from Stock 5.02) following the instructions from the OP. Installed KK bootstack before the ROM.
But the data network is really unstable: it takes a long time to connect to data, 4G works rarely. I tried several options for "preferred network type", but no one works well.
Do you have any suggestion?
Thanks
Edit: I am not allowed to post on the dev thread

have you properly wiped the device before flasing cm?

[Q] Data connection not working after flashing custom rom :'(

I'm having a problem since I flashed the sensation rom (by crysis21) on my SGS2 yesterday.
My internet connection (mobile network) doesn't work anymore
I checked the APN settings and already resetted them and enterd my APN settings again. But it still doesn't work. I also restarted the phone multiple times.
Does anybody know where the problem is?
Installation steps were:
*copying the rom to sd
*CF-rooting the kernel via Odin
*booted up in CWM recovery and chose "install from zip file" and installed the rom (without any wipes)
Before I had the default samsung factory rom on it.
Have I made a mistake?

Have you checked the APN settings are the good ones? One thing is to have ones enabled and other totally different is to have ones that actually work.
Also when you go from Stock to Custom ROM you should do a full wipe!
Go to CWM and format /system, /data, /cache and reinstall the ROM.

thanks, I'll check this out as soon as I get home.
I refrain a little from doing a full wipe because I don't want to get all my apps deleted (and I'm a little too lazy to perform a backup). Would mybe a new modem solve this problem?
And of course I checked the APN settings. I deleted the existant APN setting and added a new one so the settings can't be the problem.
I also checked some entries in Settings/Phone Info/Status.
It says here (translated from german):
Mobile Network Type: HSDPA
Service State: Function (or working rather)
Mobile Network Status: Disconnected (but sometimes it says also connecting here, though it never really gets conencted)

Even though I wiped everything, the data connection still doesn't work.
I did
"Wipe data/factory reset"
"Wipe cache partition"
"Wipe Dalvik cache"
and after that I installed the Sensation rom zip file again.
The data connection still doesn't work :'( (I added the APN after install, of course - the settings are 100% correct).
I also installed another rom (infected rom) but there's still no data connection.
Am I missing something? I'm getting really desperate over here.

You could try flashing another Stock ROM via Odin and see if in stock works or not, then try a Custom ROM.
Sometimes the phone takes a while once you flash a new ROM till it establishes a decent 3G connection. Having "Data enabled", how much did you wait for the phone to establish a connection?

I thought so too... Well, at work I waited some hours for the data connection being established but nothing happened.
This is crazy. I even restored my system with CWM and it still ain't working.
As soon as my GF comes home I'll replace the sim cards. Maybe the problems at the providers side...
after that, I'll try a stock rom (via odin).
thanks for your tip

I have the same problem and I'm on check rom.
i'm having the exact same problem, but with multiple roms and not just one. i tried omega and delv. both of these are giving me no data connection (only at the beginning) but once i restart there's no data connection.
did you manage to figure out what went wrong? I've resulted in my original rom that i had by restoring it using cwm.
dear sir,
my device is micromax canvas a1 aq4501. when I recovering a custom rom like cm13 my device Internet data not connected. I fully checked setting like mobile data, apn, but it still not working.
now I want my device situable custom rom. please give me the right information.

No 3G Icon or Data Connectivity

Hey guys,
Backstory (Not sure if important): I was running Villain ROM for a long time whilst I was over seas, and every time I used WIFI, my phone heated up a lot (around the camera), to the point where I couldn't hold it up to my face to answer a call. My battery also got fairly hot while charging my phone on a boat. During this time I had a lot of issues with it crashing and what not, but data was still working. I charged my phone at the airport and then I tried to turn it on once I got home and the battery was dead. But I had a spare one which I'm currently using.
Anyway, I flashed Resurrection Remix ROM 3.0.5 (22/08/2012) and it failed to work (boot loop), so I flashed Stock Telstra 2.3.6 ROM. Then I tried to re root it and flash RR again and it worked fine. I attempted for a long time to fix the problem by using different modems, and flashing different ROMs etc, but I decided to use Triangle Away to reset Binary Count and then I flashed my phone back with the stock Telstra ROM as I may send it off for repair if I can't fix it. I also used OTA to upgrade it to ICS.
I've made sure that airplane mode is off. I've enabled data/roaming in settings. I've made sure (using power button) that data is enabled. I've checked the APN's and their all correct. I've selected the proper network operator (Telstra). I've gone into USSD Code '*#301279#' and changed the revisions.
I went into the settings using the USSD code '*#*#4636#*#*' and went into phone information. When I click 'Run ping test' it fails with the errors:
Ping IpAddr: Fail: IP addr not reachable
Ping Hostname: Fail: Host unreachable
HTTP: Client test: Fail: IOException
When I press the menu key there is an option called 'Enable data connection', that when I press closes the menu (as if it had worked), but when I opened it again, it says the same thing. There is also never a 3G or Data Icon.
If anyone has any ideas on how to fix this, or anything to try, please let me know.
TL;DR: I've read pretty much everything I could find on Google and nothing is making data work or even appear.
Thanks,
Hi !
I got the I9100 G, and tried many custom AOSP AOKP based rom too. I noticed that I can't get data network with those custom roms.
I also tried to flash modems, reflash with fresh restart, full wipe, etc.. but still nothing.
So I went to a stock based rom, with the Divine rom. And everything work fine.
Now I'm on the RR v3.0.5 and still no data, just wanted to try agan this amazing rom.
But I have to switch back again to the Divine..
Try this one, it should work if you got the same issue, even if I still don't know what it is exactly..
Note that it's for G's only !
let me know if you find another way to get rid of this.
why not try RootBox rom.. it will help you out with the data network problem,,

Check your APN settings, if it's correct
Swyped from my Galaxy SII
Rootbox for G's.. Yeah..
Already tested.. Not the latest but the v1.7 and it didn t work..
APN, modems, fresh restart, saving APN on a stock rom + restoring when on a custom like RR or RB, even CM9.. Tried all of this already.
But I didn't tried all modems..

[Q] Lost automatic connection with my data plan

Hi everybody!
Yesterday, I applied a custom rom to my Galaxy Note and after a successful installation, my data plan wasn't working like it used to be.
I have to say this isn't the first time I have done this, and in the previous opportunities after flashing the rom and rebooting, the EDGE/3G icon appeared by itself detecting my data plan. I never had to configure the APN settings (like it is said in many posts I have seen here).
So, when I realize that it wasn't working properly, I re-flashed the rom but didn't worked. So then, I downloaded the ICS stock rom and flashed it through Odin, hoping it would reset all things here and would give me the initial configuration, but that didn't work either.
I have entered through settings and deactivated/activated the options related to mobile data, but that icon never appears or my data connection showed up.
Forgot to mention that this phone was unlocked through cellunlocker by code, and that I can make phone calls with no problem and also the Wifi works fine... And thank you in advance for any advice/help that you could make
If it's happening with different ROMs then take a look at your modem (baseband). Are you using I717UCLF6? Go to System Settings-About Phone-Baseband Version.
Like ^^^^ said, and you didn't say it, but I'm guessing T-Mobile. So flash any ROM you like, reboot and let but settle in, then flash the Blaze 4G or whatever T-Mobile modem works best for you.
You did enter your APN info?

No mobile data with CM12.1 Stable( 19.11.2015) from Lolli. - Do I need bootstack?

I am new to this forum, but I read so many hours and thanks to this great forum I was able to flash cm12.1 on my LG G2 mini(D620r).
This is really a great rom, everything works very good. except one detail: mobile data, I have the "!" next to the symbol.
I used cm12.1 for some time on my Samsung S2(I9100, CM12.1 with Dorimanx Kernel and Stweaks to change settings) and I missed it so much when I got the g2 mini with stock rom.
For the LG I really had to read a lot(english is not my native language) to understand everything. The CM12.1 for S2 was much easier.
I did it this way:
LG G2 mini(D620r) Stock ROM Android 5.0.2 (should not have done the update from KK)
1.root
2. unlock bootloader(patched)
3. Custom Recovery TWRP v2.8.7
4. wipe everything except internal+sdcard
5. flash cm12.1 stable + gapps pico ... cm12.1 works perfect.
except mobile data, I did notice this very late, cause I used the g2m only with wifi.
I tested different APN settings, but I could not get a mobile data connection. (it tells me that it is connected sometimes, but it does not work)
I put my SIM card in a lg g2 with stock 5.0.2, works perfect. same with my old samsung s2 cm12.1
"CM12.1 does not need any bootstack in the latest version" is written in the CM12.1 Thread, first posting.
Could it be that something went wrong and I have to install the KK Bootstack because I am still on L?
is it possible to do this now and than SIM works again as it should??what else could I try?
I tried some other versions: 28-12, 30-12 and 01-01-2016. with all the same problem.
I read in a german forum about a guy with same problem(but other smartphone), he installed cm12.1 at least 10times, also different releases ...finally for him a different baseband worked. But I know not much about this...
Thank you, I am sure someone in this great forum knows about this problem

Hi. Your problem is very specific. I have D620r too, and no problem with mobile data. But I use KK bootstack. You can try flash Carbon rom which is based on CM 12.1 or try this version and find out, if problem is there too. Be sure, you format system, data,cache for clean installation. If problem is still there, you should try KK bootstack(recommend as last option). Maybe somenone else will help you, I really don't face this problem.
Good luck!
Thank you, I already tried bootstack v1.5 KK 5min ago. I still have this problem.
When I put my sim card in the s2, I get some sms from fyve(vodafone) and apn is set up and so on..nothing like this with the g2m
I will try to get some other sim cards an look if there is the same problem.
and will get carbon rom...but it is be not so much different??
does anyone knows somehing about this baseband thing?
EDIT
Carbon Rom does not work. ;(
I will go back to cm12, this should work
I flashed CM12 and now I have mobile data connection again. seems to be a problem just with cm12.1!
But if anyone knows what could have been the problem please tell me, i have a full backup and would prefer to use cm12.1
thank you
Omg, something went terrible wrong.
I installed a ROM(DroidMaster Lollipop-lite) and thought I also would need the Bootstack for L.
So I restored the backup(Druidmaster) and the bootstack...no I lost the IMEI, WIFI MAC adress ...there is nothing left^^
The system boots normally. I have done a backup(TWRP) of the system, should still be there.
I will try this.
please tell me if there ist any hope to restore this g2mini???

as i know you dont need flash right bootstack on newest cm12, you can flash it on kk or l - no difference.
take it easy, flash stock fresh http://lg-phone-firmware.com/firmware-LG+G2+Mini-Tutti-57.html by lg flash tool (you can find easy some tutorial), for example v20a or v10.. (first is lollipop second is kk) and make every step again.
Droid master you can restore only when you was on L and will be no problem. If you need CM12 just install fresh kdz file of kk, root it, unlock bootloader, install twrp then cm12 and will be ok.
I restored my backup of cm12.1 because I was worried about the missing IMIE and baseband. After the Backup I had my IMIE ... again, everything works except mobile data.
I don't know what exactly is the problem: mobile data works with every ROM except cm12.1 (no matter which version I take.). I would like to report this problem in the cm12.1 thread but I don't have permission(not enough postings) maybe someone could help me. because of all ROMs I like cm12.1 most.
I will install cm12 and look how this works and if there are any bugs. If I don't like it I will go back to stock with the flash tool 2014 and kdz(already done this once)
thank you

In CM 12.1 go to settings >> mobile networks >> Acces point names (APN) and if you don't see there nothing, you have to configure it. In google find apn settings of your mobile network provider, some guide or tutorial and configure it or just remember apn settings from work rom. Good luck.

You have no data mobile on CM13 too?

[HELP] No mobile data after flashing custom rom

Hello everyone !
I have a problem : When I flash a rom (Nougat or Marshmallow), I do not have any mobile data. I can always make calls and receive messages but when I activate the data, I do not have the symbol 3g or 4g and impossible to go on the internet (it tells me that I am not connected to any network) or Receive MMS.
I tried several ROMs based on Android 6 and 7 but the problem is the same, I also tried to flash different firmwares but it does not change anything while on Xiaomi.eu or stock MIUI ROM I have no problems.
I checked the IMEI and the APN, everything is correct.
I also tried the VoLTE patch (Android 6&7) but it did not change anything.
So I'm asking you the question: Do any of you have a solution?
I use the lastest Resurrection Remix ROM with the MIUI firmware (7.3.9 by @reemar)

Thanks for your quick reply !
I do not understand very well, once in phone information, what should I do exactly?
Thank you in advance !
I've been encountering similar issues with no data available... what helped me is I simply installed ROM I wanted and then restored EFS (partition or whatever it is) from a ROM backup I am sure data works....
Just check your APN settings...
I had similar issues after installing some google apps packages - don't remember which exactly. Try to install fresh rom without Gapps and check if problem still exists. If not, look for good Gapps. It took me whole day to find which caused this.

I have had a problem with mobile data transmission on Xiaomi Redmi Note 7 (Lavender). I installed various custom rom Android 12 and unfortunately on any of them I had no internet connection via Mobile Data. WiFi worked, phone calls also ...
Here's what helped me:
1. I installed a custom rom based on MIUI (of course, first Orangefox, and then MiUI Wolf Os for Lavender). After installation, everything worked, there was an internet connection via Mobile Data. The SIM card was even on Sloat 2 and everything worked!
2. I installed Awaken OS 2.9 for Lavender (with gapps). When I was asked to insert the SIM card during the installation, I put it into the slot 1. Unfortunately, Awaken 2.9 does not support the mobile internet on the slot 2.
Why does this solution help? Because this way of installing Awaken OS does not destroy firmware from Xiaomi. I hope it helps you too and will work too for you
