Hello. I have a Kate with running Global Dev 6.12.8. All is running well so far. But if I flash custom ROMs I don't get a mobile-data connection, but I can make a call! WLAN, BT, GPS...all is running, but no data with sim-card. APN is correct, too. When I go back to stock with TWRP-backup, mobile-data is running back! I testet custom MM and N ROMs...Slim6, RR, CM...I testet CM14firmware, too.
Check the custom rom threads for advice on flashing on the Kate, specially which modem firmware to flash. (NON_HLOS.bin)
[Tools, Tips & Tutorials] How to install CM13 on KATE (rn3 pro special edition)
Note step 7 and Step 29 to 38.

Still no mobile-data-connection! This happened with the Dev-ROM update from 6.11.x to 6.12.x. Is it possible to downgrade the DEV-ROMs?
I have the same issue - I had CM 13 running for weeks without issues on my KATE device (using this German tutorial: http://www.android-hilfe.de/thema/h...-note-3-pro-kate-band-20-installieren.795136/ - un-official boot loader unlock). After trying CM 14.1 I have no data connection but APN settings are correct. If I switch back to Stock ROM (e.g. kate_global_images_6.12.15_20161215.0000.00_6.0_global_9e944aa495.tgz) mobile data works again. I've flashed NON_HLOS.bin from different fast boot files but nothing helps. Even CM13 does not work with mobile data connection any more.
If someone knows a solution I'm thankful for any advice. Complete re installation is no problem.
I know used the link above: http://en.miui.com/thread-363264-1-1.html But replaced the files mentioned there with CM 14.1 nightly build + this (http://forum.xda-developers.com/redmi-note-3/how-to/cm14-14-1-aosp-n-firmware-kenzo-kate-t3507789) Firmware for kate and Cm14.1) And I flashed modem from global stable directly after GApps (I did all wipes mentioned in thread). Instalation went perfectly fine and CM sets up correctly. Even while 1st setup it detects my SIM and my German carrier correctly. But after setup completes there is still no data connection (One detail: CM setup asks twice if to enable mobile data connection while setup - I confirmed both of course...) Phone calls and SMS works fine....
I could cry because this makes the phone unusable for me and I have to go back to stock now... Camera, FP. Bluetooth and all that stuff works fine ...
You could try to perform a soft reboot and see if it helps. I'm using this workaround for like 2 months.
I'm gonna try OPs guide after Christmas.

Thanks for the hint. Will try after Christmas - now I'm back on stock and have to take care of all the presents - no time to play around with my cellphone any more
Have a nice Christmas

I'm on LineageOS now following this: https://forum.xda-developers.com/redmi-note-3/how-to/kate-guide-install-lineage-os-locked-t3546154
guide but same issue: NO data connection
Soft reboot trick helps. Did you find a permanent solution for this issue?

Thanks. Since I installed LineageOS already I tried to adopt this procedure for me and it seems to work:
- The guide tells "put SIM-Card from SIM-Slot 1 in SIM2-Slot2 (leave SIM-Slot 1 empty!)"
Since Sim1 is Micro and Sim2 Nano in RN3P I don't want to cut my sim card - so I simply took the nano card out of another phone started once with only sim2 inserted:
- Data connection OK
I re-inserted my SIM1 only again (after shutdown) and connections ist ok, too 4G LTE in Germany (kate version)
Thanks again - have a good weekend.

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.

... or just try CM13 if you like this type of system. Now is official and every bugs will be fixed from time to time very fast.
You have no data mobile on CM13 too?
I just extracted the firmware files from the HYDROGEN 2.5 beta/(now Oxygen 3.5.6) release.
Just flash this and then LineAge OS/former CM14.1 official(Confirmed Working) and get VoLTE working..
VoLTE working perfectly (no RR and network drops)with modem ver 1.2
FLASH ON YOUR OWN RISK, AS we are Tweaking Modem Firmware
LineAge OS/former CM14.1 already has VoLTE patches in it.
Just Found out OxygenOS2 also had patches so v1.1b is working on it.(Confirmed for V 2.0.1)
If you have flashed on oxygen.3.1 to reset your phone
follow oneplus china's guide
EDIT : You will end up giving up your IMEI 2 if you rolled back to old Firmware
Fix for Missing IMEI in older ROMS:
The new modem changes the way IMEI is stored, so in older ROM's like OOS3.1.0 you can enable the IMEI by simply flashing the new H2OS modem on the ROM(OOS3.1.0) and it will enable the ROM to read the IMEI for Slot2 ​
And edit build.prop and add
Code:
#ifdef VENDOR_EDIT
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=0
persist.data.iwlan.enable=true
persist.dbg.wfc_avail_ovr=0
#endif
In the end for getting volte working
Fix for Random Reboots(CM14.1) and Network Drops(H2OS) :
Download Network Signal Guru from play store.
Give root access and start testing from 3 dot menu.
Now click magic wand and select BAND LOCKING.
Select only the band with best strength( 5 in my case) and uncheck rest of them.
Stop the testing
AND You are good to Go
Mine Network stable since 3 days.
Even you can get VoLTE working in OOS 2.0(Lollipop):
Oneplus tried to implement VoLTE for Oneplus2 back in the development days of OxygenOS 2 and the have VoLTE patches in it too. So If you flash the modded zip of the VoLTE modem you can even get VoLTE calling working on OOS 2(Tested on 2.0.1).
Download :
v1.2 here
v1.1b here (For Lollipop/Older Bootloader)
Just hit a thanks if I saved your time from downloading whole OS zip.
thnx dude
Finally, the whole "is volte working" thing comes to an end... May God bless us all! :laugh:
That deserves an applause...:good::victory:
I have not tested it but hope it is working. Thanks for this
Hi guys,
Just a quick update from my side.
It's not working here in Canada. My carrier Bell does support VOLTE but it still goes to H+ (HSPA) when in call. Not sure what's wrong here. Or maybe OnePlus has a different radio static_nvbk file for the North American OnePlus 2 model.
What do you guys think?
Can i flash this on a cm13 based rom too??? Or does it require cm14??

no one try this unless you backup your efs.
i was using cm14.1. there people says flashing this zip can enable the VOLTE, and i did, but that didnt work. it was as usual (except some extra options in PREFERRED NETWORK tab). so i want to reset it by flashing the rom. it didnt work. so i flashed the OOS v3.1.0. But that gave me no IMEI and i have lost both imei and no wifi connection. Also, phone is rebooting randomly. Few months ago, i have backed up my imei (2 modem files), but when i try to restore it, the adb cmd doesnt show my phone in FASTBOOT MODE...

You might wanna add to the OP that backup efs is mandatory.. Even a little hint about the risks of tweaking modem files would be useful! You know how people are, they flash first before they think..
V1.1? What is the difference according to 1.0?

You have a backup of efs via twrp? Does recovery still work? Did you try to clean install? Maybe if you flash the modem file of 3.1 you get it working again.. But now is a point where you should think thoroughly before the next step, one step killed you efs / imei and I guess not OOS3.1, even H2os is unlikely.. Looks like a big mess

OOS 3.1 wont work after trying flash H2os 2.5.. it wont connect to wifi or even show simcards, and even if it will boot it will keep rebooting.. same thing happened to me yesterday.. I tried changing the recovery to hybrid, even tried flashing the modem from OOS 3.1, that didn't help either and then tried flashing cm14.1 or even Exodus 6.0.1 but nothing booted because of course the recovery was wrong. And when I tried flashing OOS 3.1 my mac address was weird and not the usual one.. so I did later was, I flashed h2os 2.5 with same recovery, hybrid one, booted the OS, when it went to wifi it showed me my usual mac address which confirmed that wifi was working then I rebooted and went into wipe, did factory reset, then wiped cache, dalvik, data and system, basically except internal storage everything.. then I installed the latest TWRP which is 302-2 from install image and then flashed cm14.1 and gapps etc. and everything started working again.. sim cards wifi everything else too.. I havent tried installing OOS 3.1 again.. but I think flashing gapps along with h2os 2.5 doesn't let you go ahead with the setup and flashing h2os 2.5 installs new modem which completely breaks connectivity in OOS 3.1

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
Hi guys
I have problem with my touchscreen when the antenna switch between 2G 3G 4G when someone call me or I receive sms, specially when data connection is active...
for example when my sim card is on 4G and someone calling, the antenna switch to 3G or 2G witch is normal BUT the phone touch itself and may be reject the call automatically...
I flashed my phone to 7.0 and 7.1.1 more than 3 times but it didn't fixed...
Does anybody have this problem??
Is it a bug from android 7 ???
should I flash to 6.1.1 ????
plsss help!!!:crying:
please give details
1. how are you flashing? seems like your boot is unlocked
2. if yes, then wipe everything and start fresh (userdata, master reset, all options)
3. if you have already done that then try different region's stockrom (xperifirm) and flash that one. (we have now two 7.1.1 rom released)

the reason i asked about boot unlocked status is to make sure no foul play was done with device! for example with unlocked bootloader thirparty roms can be flashed LINEAGE , X roms and if they ever had, chance may be that touch/wiz has been compromised.
if you had dropped your phone touch goes crazy.
so it was a question just to answer many doubts automatically.
if its not hardware problem then android 6 would work just fine
Hello guys,
as the title says I am currently with the mobile data connection not being established on custom ROMs, the official MIUI ROM works fine. Before trying to go to LineageOS 14.1 I ran this 13.1 ROM for quite some time successfully.
This is what I did since trying to migrate to Andoid 7.1:
I flashed the latest MIUI Global Dev ROM, this locked my bootloader again, so I tried this for installing TWRP and custom ROMs with locked bootloader and this for unlocking the bootloader unofficially. Both methods generally worked, but mobile data did work on neither of them (I checked for the correct APN).
So I tried to go back to the LineageOS 13 ROM (clean flash, since I accidentally deleted my backup) I used before, but it also does not work on that version anymore.
Does anyone have any idea what the issue could be or how I could possibly find out what causes this?
Edit: I am now actually back to the latest MIUI Global Dev and hoping that I am able to unlock the bootloader officially eventually. But any tips on the issue above would still be appreciated.
Edit 2: On the 8.0 NitrogenOS mobile data does work. I first thought that it yet had to be an APN problem, so I copied the settings from this ROM to the LineageOS 14.1 ROM and deleted all other APNs, but that actually did nothing, it still did not work. So I guess I will stay on 8.0 for now, although I wanted 7.1 because of XPosed.
Edit 3: Suddenly stopped working on Android 8. Seems to work on the first boot after flashing a Android 8 ROM and then not anymore. Going back to MIUI...
This post helped me with the issue. After a soft reboot mobile data just works fine even after enabling/disabling airplane mode.

Did you find a persistent method to solve the problem?
I have the same problem but Mobile Data only works after first boot and first soft reboot - than never ever.
BTW it works on MIUI ROMS without any problem.
