[Q] unable to get data connection

Hi guys,
I'm being annoyed by my SGS about his data connection. Hope someone could help me!
Few days ago I flashed MIUI Mintberry 2.1.20 and everything was working like a charm, but this morning data connection switch failed several times.
I've tried to wipe everything, re-flash Mintberry and even to flash JVU stock with Odin, but I still can't switch on my data connection.
I can't even see any icon on the status bar.
Any idea? Is my phone broken?

Hmm this is strange, so you turned data on but theres no symbol, right? Have you tried installing another kernel (maybe also applying the Kernel Cleaning Script)?

I' ve tried everything with Odin, and at the moment I have a beautiful black screen of death.
Odin cannot recognize my phone... I'm very frustrated
EDIT: Upgrading Kies'drivers, I managed to connect the phone with Odin again, so I've flashed the lastest official stock firmware to check my antennas. In the worst case, I'll be able to go to the shop for assistance without problems.

Have u tried typin ur apn maually?

Sounds like a settings issue. Never heard of anyone have this problem before - I've flashed every version of mintberry including betas.

I just had this issue
I just had this and figured out what is wrong, its a easy fix too! Just go to settings and wireless and change the access point for your mobile connection. I had 2 access points and just switched it to the other one and my data started working again!
Hope I could help

Hi guys! thank you for all these answers!
I've tried to set APN manually, to change custom ROM and custom kernels and coming back to stock too, but still no data connection icon (neither data connection itself).
At the moment, I'm on JVO, the latest official italian firmware, everything is fine but 3g data connection.
Other ideas? Shall i need of Samsung customer service (I hope no!)?

Solved...
MIUI default settings fault: SMS notification has ran out my money and my provider has blocked 3g connection.
My phone is safe!

[Q] No Service/No contacts?

So this is my first time rooting/flashing so I'm not a pro at what I'm doing but I wanted to give it a try
Anyway, so I rooted my S3 Mini with Unified Android Toolkit and backed up apps etc. Then installed CyanogenMod on my phone. Everything is okay except for 2 issues.
1) I haven't got any SIM Contacts, were these deleted when I wiped the phone and now I can't do anything about it?
2) I see 'No Service' on my phone when I bring the toolbar down from the top of the screen. See this is weird because I have service and am using the internet, but I don't actually have a registered network. I went to network providers, scanned and tapped my network, but even then, there was no change. I am running a UK S3 Mini on baseband ...XXAMJ2 and Installed Jellybean 4.1.2 (CyanogenMod 10) 20130727 from Maclaw'NovaFusion
When I rooted with the Toolkit, I chose the option [Up to ALL7] if that makes any difference?
Is there any way I can see which network I'm running because I'm confused and was gonna just flash the stock rom and unroot...
Thank you
P.S Also just checked in About Phone and my Network/Service Status comes up there, and my mobile data works, but it still says No Service when I bring the top toolbar down?!

For the SIM contacts: Try to pop in you SIM to an old phone and check if the contacts are still there, if yes good, if no... my condolences.
I strongly recommend to switch to CM11, it's working just fine, with no major bugs or problems. Well, i'm using it and i'm very picky when it comes to bugs and other issues.
The point is, you have to re-flash you phone anyway and along the way, you can update to a better android version.

With switching to CM11... I'm currently on 10 because my S3 was running 4.1.2 originally, if I were to flash the 4.4.2 rom, would it work and be compatible? Sorry if it seems like a basic question, I'm not really that knowledgeable about this
EDIT: Just did this, worked wonders! Thank you!

[Q] Problem LTE Galaxy S3 Wifi and Mobile Internet

Hello everyone,
As the title says I have a problem on my S3 (i9305).
First of all I want to know that it has been dropped or anything,
I put the official version 4.1.2 (the DBT for Germany was the latest then) instead of 4.0.4, rooted + busybox + modem network Vodafone Romania (XXBLL5) and it worked just fine until yesterday.
I arrived at work I checked my mail via wifi network, I disconnected I put on charger and after an hour I removed to make some mail and then give it to initialize wifi stupor show he wants to start and stop and did not want in any way to start a (looks like starts and stops).
Good now seeing that I got it and I somewhat empirically and did the following things:
-clear cache, wipe Dalvik, reset permisions - still did not work
-restore the Nandroid for wifi - did not work
I managed to got mad and threw factory reset - still not working height
-continuing with nervousness I flashed phone about 4 times with different versions 4.1.2 and version 4.3 but bootloader of 4.1.2-
Normally he did not want none and some gave the "camera failed" error.
All versions have been flashed after wipe cache, dalvik and factory reset so I say something to remain excluded from one another.
Now I'm on a Vodafone version 4.1.2 on sammobile after I haunted a bit on the internet I saw that its more people with this problem and someone had an alternative after you rename the file "wpa_suplicant.conf" in root / data / misc / wifi.
I did this and go but it is something temporary peak for once stop or restart your wifi is not working and another thing
mobile internet does not work without you come in APN and reset its there.
Sorry I did read both but I do not understand the phenomenon and to solve it because there can not be a hardware problem but rather a problem or write permission on the root folder.
And now comes the question: is there a solution to my problem or a way to see if some parts are protected to rewrite or corrupt?
Sorry for my english i use google translate.

Cant Turned on WIFI/BT, Already Flashed for BT still not working

Hi , its been a year since i bought xiaomi mi 9-global rom(128GB) and all work properly.
if im not mistaken the first rom when i bought is MIUI 10 , then the last time i update if im not mistaken is around september in MIUI 12.02 for the latest security patch.
Suddenly problem occurs recently maybe around a week. where my Wifi & Bluetooth disconnected by the system and cant be turned on but it fixed it self as i restart and now its never fixed.
I already some of fixed below :
- Restart devices
- Wipe all data
- Factory reset
- Try to flash the ROM from official one MIUI 12.02
- Following some tutorials that reset bluetooth and wifi settings
- Try downgrading MIUI version to 11
but still didnt work the Wifi & Bluetooth setting always crash & cant be turned on , try CIE or CIU test found out that the proximity sensor also didn't work.
I also tried some tutorials that do in EDL mode to install persist mode but its not working due to the Authentication it says" i dont have the permission"
Is there anyway i can fixed the Bluetooth & Wifi in this device?? The Mobile Data is still working and other features still working except Proximity Sensor, WIFI, Bluetooth.
Is the only way is to let the xiaomi store fixed it?? this is my only phone so i need it alot and the office store probably going to take long since pandemic.
Please help me Xiaomi Pro's out there :crying:
Edit :
- my xiaomi account already match with the phone the proof is i can unlocked OEM using the xiaomi. But it seems i still dont have permissions to flash EDL.

I think it's safe as miui could be.
But be shure to follow step by step and take right rom version. If it's working you can flash original miui or custom roms.

Thanks for the suggestion, after i tried to flash to EU ROM i got new MIUI version which 12.04 , in global its 12.02. However the problem still happening or still remain unsolved. The bluetooth & wifi still cant be turned on, i tried on CIT it also not working and everytime the i try to open wifi & bluetooth settings , the settings always freeze and crash probably because it error. Is there any other solution you can provide?
Thanks

I think, if you have done a really clean flash with formating data, that it's a hardware problem.

yes, i did i already follow the instructions & having no error at all for the ROM and other stuff except the WiFi & Bluetooth.
But for me its just really weird, my phone looks still great from outside no bend, dent, or crack it never fall as well.
The problem starts occurring by itself like the system is forcing the Bluetooth & WiFi to off then at some point the WiFi is connected but not transferring any data after restart everything fixed then its not working at all, which when i tried to turn it on it will freeze or the system not responding or off by itself.
btw appreciate your answer, i'm still waiting for other solution if possible :crying:

Are you shure that you've got a global version. I had nearly the same probs as I've flashed the global on my eu hardware.

In my personal opinion there're 2 possibilities
Damaged hardware
Or
Modem Partition wrong or damaged
MODEM or RADIO - the phone's radio
Also called baseband, it is responsible for signals and on older devices may control wifi, bluetooth, and GPS (on most newer devices, these are handled by the kernel and ROM). Upgrades are country dependent and may improve or diminish battery performance, network signal strength, and roaming capability. It is also sometimes required to have a minimum Baseband version to use a ROM so that the RIL will play nice with the Baseband.
Modem firmware is a mini-OS for the cellular radio chip which has its own processor. Firmware is a general term, firmware exists for a lot of things on phone. The wireless chip for WiFi, GPS, and Bluetooth often has a firmware as can the GPU core among other things. These firmware files are usually located inside the SYSTEM or VENDOR partition. The modem firmware is special because it has its own separate Baseband Processor (BP) so the firmware is left out of the system image in its own partition.
Modem is not an Android-specific partition. It is tied to the hardware of the phone, but the kernel has a code allowing Android to interact with the hardware. But the baseband processor (BP) - which runs modem and is responsible for all communication through mobile networks e.g. call, SMS and internet - is totally isolated from Application Processor (the one we call CPU) and is not governed by Android kernel; it runs an independent RTOS.
May it helps you for getting a solution....

Maybe i just dont have any other option except to fix in mi store.
Once again thanks for the help :fingers-crossed:.

XT1925-4 wifi problem please help

Hello guys im new here and i tried lot of things to repair my wfi problem.
So its my mom phone and one day she called me about selfrestart phone in night and there was image of bootloader and startup failed.
So after classic factory reset and etc my wifi still not working. The problem is i cant connect to any wifi. I can scan it but wont connect just say disabled or saved but not connection.
After this i tried flash stockroom succesfully after 2 days of hard work So i flash stock room but the problem is still there so im not sure what can i do anymore. If i can try flash some newer rom or custom rom or its just hardware failure? has anyone have problem like this? All others things work normal like data connections etc. Sorry for my english
1. update so i flashed another lineage room just in case and still not working.
2. i notice in system information that wifi mac adress is 0d:00:00:00:00:00 so can be hardware failure probably.
3. Hotspot wifi is working so i can connect from another mobile to the broken wifi mobile
