[HELP] No mobile data after flashing custom rom - Xiaomi Redmi Note 3 Questions & Answers

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

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.

No mobile internet after Rom flash

Hi,
I recently changed my ROM from Cyanogenmod (some of the last nightlies; so Android 5.1.1) to a custom rom called "existenz".
After successfully flashing the 6.3.5 Premium Update to my phone, the mobile data stopped working correctly.
Whenever I try to enable mobile data in my settings, the trigger simply goes back to disabled.
Reason for ROM change: I didnt want to use nightlies anymore and this ROM seemed perfect for my phone.
I tried several restarts, but nothing changed.
I flashed the ROM with TWRP.
Thanks in advance,
Pascal
(If nothings helping, whats your custom ROM you could suggest me?)
I flashed the latest nightly of cyanogenmod again. Mobile data is working now. Guess I'm never leaving cyanogenmod.

Are u sure u enabled ur APN settings from settings/more/internet settings?
For ur information only CM roms will enable Internet Apn automatically after flashing rom. Sony custom roms did not enable Internet APN automatically. We need to set it by ourself or u can install internet APN from settings/more/internet settings
@Rajeev
Good point. I read something about "allow only IPv4" - so I changed that - rebootet my phone but still nothing.
I cant remember tho about anything saying its disabled. Might give it a second try then, havent fully configurated my phone yet.
Thanks.
Only turn ON internet data and go to config / •••More / internet settings- Download settings for Internet and MMS

No data-connection on custom ROMs

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)

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. 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.

No mobile data on Redmi Note 3 (kate) on custom ROMs

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.

[HELP]VoLTE not working in any 7.0/7.1 based custom ROMs on mido.

So, I was using ViperOS as my daily driver and all was working fine but a month ago I flashed MIUI 9 to give it a try.
As I'm a stock android fan, I got bored from MIUI and decided to roll back to AOSP based ROMs .
So, today I flashed LineageOS latest stable build along with proper gapps package. Everything was working as usual except VoLTE. I thought there might be the problem with that particular build so wiped again and tried Ressurrection Remix and AOSP Extended but the same issue prevailed.
I checked all network related settings but all were normal.
I googled it and found a fix that was in the IMS Settings in the phone dialer but when I click on IMS Settings, a message popped up saying com.android.phone has stopped. I tried this fix in other ROMs too but the same message kept on popping up.
Moreover I ran ping test using *#*#4636#*#* and got the following results:
Ping Hostname IPv4 : Pass
Ping Hostname IPv6 : Pass
HTTP Client Test : Pass
Data Connection Real Time Info:
Message Waiting : False
Call Redirect : False
I found the same issue in the LineageOS Forums and it is solved too but I didn't get the solution. Here's the link to that LineageOS Forum's thread:
jira.lineageos.org/browse/BUGBASH-588?page=com.googlecode.jira-suite-utilities%3Atransitions-summary-tabpanel
Now unfortunately I'm using MIUI 9 which is the only option I have
Any help regarding the issue will be appreciated.
Flash the latest frimware.
Had same issue in 3s prime.
All i did was
1. Installed Miui 9 through recovery
2. WIPED ALL PHONE (INCLUDING SYSTEM, DATA , DALVIK, CACHE,INTERNAL STORAGE)
3. Again installed custom rom ( RR Final build )
4. Flashed LATEST FRIMWARE
5.installed gapps
6.Done
Got VoLTE Fixed.
Facing the same problem...i don't think its the firmware problem..i have tested two different firmwares .
Can you send the link for latest firmware ?
go to access point names and create a new copy of the exact access point you're using before and then select that new one. Connect to internet and reboot.. see if that works
No it doesn't.

As I mentioned I tried all network related settings including you suggested but nothing worked.
There's a solution in the LineageOS forums but I didn't find that.
