I'm hoping someone might point me in the right direction for restoring cellular functionality on a recently flashed GT-I9300 ?
Essentially what I've attempted to so is up-cycle an old Samsung Galaxy so that my son can communicate with myself and his grandparents on Signal.
System: RR-N-v5.8.5-20180914-i9300-Unofficial
Recovery: TWRP 3.02.1
RR is up and running (and quite slick!!) and generally there appear to be no issues apart from:
- SIM being undetected
- Baseband version: "unknown"
- Settings --> Wireless & networks --> Cellular Networks: APN / Network operators / Preferred network type; these are all greyed out
There's a brand new sim card in it (two others have been tried); I just need a way of helping RR discover the correct settings needed for cellular functionality? I wondered if there might be a modem config file somewhere I could edit - but I've not got that far yet, and I'm not even sure if this would be the right approach. Any suggestions would be greatly appreciated
Hi,
I presume you have no backup of your /efs partition ?
Have you tried another ROM ?

Hi guys,
few days ago I've decided to move forward with Fusion Update 7 ROM to Fusion Update 8. Procedure was about normal beside the fact I had also purged SD card. Upgrade went well, but:
I cannot get mobile connection
No SMS can be sent
No matter which ROM/RADIO I had flashed after my previous move everything beside those two is working. So I can get WIFI connection or receive SMS, I can also call and receive calls.
My configuration:
- Hardware: HTC HERO GSM (white)
- Recovery: AmonRa 1.7
- ROM: FROYO_2.2_elelinux_v2.2 (at the moment)
- RADIO: 63.18.55.06OU_6.35.15.01 (at the moment)
Additional info:
- SMSC is set correctly (checked using *#*#4636#*#*)
- APN list is correct
- rollback to vanilla 1.5 ROM from RUU not helped
- other SIM cards from other carriers work the same way
I trying to get some debug information using adb, but only thing I can find is that ppp connection is missing in netcfg.
Do anyone know how to initiate Mobile Connection through adb shell ? or anyone get similar problem before?
Thank in advance,
Problem solved. During messing with ROMS my SIM card must been somehow damaged.
After more tries with other SIM cards my phone started to work finally.
You are missing the correct apn settings for your mobile data and also missing or have the wrong SMS service number, have a search on the forums here, or Google and you should find them. Always worth backing these up or writing them down, as not all rom's have necessarily got all providers son's included.

Thank you for fast reply.
I checked those before:
SMSC:
- refreshed with *#*#4636#*#* and those looks correctly for my carrier
APNs:
- there where missing fields in APN config which I've updated according to carrier configuration
Still nothing had changed.
I assume that it must be some kind of config that do not change between ROMS.
(I will update first message with those info.)
Did you checked with an other SIM/carrier?
Yes I did.
Effects where the same.
I've also rolled back to vanilla 1.5 ROM from RUU. Nothing changed.
It must be some kind of external configuration that is not changed via ROM replacement. Can this be true?
Thread moved to Q&A.
Hello there!
I recently installed the UltimaRom V.6.0.2 on my Gti9300.
Everything seems to working grand other than the data connection which does not function, 'mobile network state' is 'disconnected' and 'roaming is 'not roaming' under status in the settings (please see attached screenshot) so cannot choose internet, whatsapp etc.
This has been checked in the mobile network options, but this will not function regardless. I then thought it might be due to the option to install the baseband version and I chose I9300XXDLI8. Is this where the problem lies since I am receiving and still able to make calls and texts.
I am a t-mobile customer in the UK with 'everything everywhere', I believe the APN settings are OK. I can still send and receive MMS, but no data connection...
Please help me out!
The Rom on installation gives me the choice to install the following baseband versions:
XXELJ2
DDDLJ1
NEDLI1
XXDLID
XXDLIB
XXDLI8
Have I installed the wrong one?
Hi. Yesterday I installed latest nightly version of CyanogenMod 11. Before this, I was using [LINARO/SABERMOD] unofficial CyanogenMod 11 but I had problem with data roaming. I thought that in official build this isue had been solved. Unfortunetely, my data transfer still doesn't work. In the place where I live, there is very weak signal and I have to change my operator to another one manually. The problem is, data transfer works only with my parent network. I enabled data roaming in options menu and I edited build.prop file, where I set dataroaming=true; (although data roaming was enabled, in this file value was set as false). Tell me please, what to do. I don't want to restore stock rom.
Bump! I'm having same problem using CM11 4.4.4 (nightlies) for my S3-i9305. My carrier uses its own network but also uses another one as MVNO. Well, I connect HSDPA 3G on its own network but don't when using the MVNO, only Edge/GPRS (2G). Same happens using a SIM from another country, data works but only on Edge/GPRS (2G).
Yes, data roaming is enabled (the proof is that data works, but only 2G not 3G).
Any ideas? Thanks.
Solved
Ooops, it results it is a question of bands: the phone does not have all the bands we use here, that's it.

Hi,
I own the Leagoo Lead 1 (MTK6582 phone) and followed these instructions to root my phone
http://www.needrom.com/download/leagoo-lead-1/
Everything else works, but I have no network service. I tried everything, checking hidden settings (for radio setings), checking correct APN:´s, re-rooting etc.
I can either get the network to work via using "GSM only" (so no data connection and even SMS wont work)
or then using "WCDMA only", only data conneciton, no voice call possibility or SMS/MMS
This is really strange that both voice & data wont work at the same time!
Can someone please instruct me what I could do:
1. try to flash some other radio? I read there are some risks involved with this --> but what kind of radios could I try (I.e.could some HTC or Samsung specific radio work)
- if so, what should I name the .zip file for it to work in recovery (I tried putting one radio file to my external SD and flash it in recovery but it wont do anything)
2. Can I try to flash some random Android ROM to my phone and see if it works? I know this is a big risk but I searched the forum and found some "custom ROM"´s that might work on many devices.
3. Is there some way to edit the radio settings except the very basic options in hidden commands --> radio settings. (i.e. can it be related to me being in Finland vs. some other region?)
Thanks for your help.
Cheers.
Can any of you experts help me on this ?
thank you
Hi,
I have a problem with my Xiaomi Mi5 phone and a new sim card.
LineageOS version: 14.1-20171205-NIGHTLY-gemini
With the new sim card I can only call and text, but there is no data - I cannot connect to the internet (only wifi). The sim card works in other handsets.
I called the provider and we tried to manually set the Access Point Name (APN), but we failed.
In the APNs settings I see the following message: "Access Point Name setting are not available for this user".
When I try to edit access point (3 dots and +) and try to save the new settings, it also fails - there is no profile/access point name.
I already did the following:
- factory reset
- updated TWRP
- updated my firmware to the latest Dev version
- flashed the latest LOS built again (I had the latest update before)
- flashed the previous LOS built
Nothing helped.
I decided to root my phone and follow this quide: https://android.stackexchange.com/questions/117125/how-do-i-add-an-apn-via-adb
When I try to get the list of carriers I see the following error:
Error while accessing provider:telephony
java.lang.SecurityException: No permission to write APN settings

Is there any solution to my problem?
Please not that it's the first time I rooted my phone, so I count on your understanding
I really feel like I am out of options.
Thanks
I just flashed the latest MIUI 9 global stable version and it's the same. Still no data, still cannot add/save APN
I feel hopeless.
