Network Failure - "Download failed. Disconnected from Wi-Fi Network. - Galaxy S III Q&A, Help & Troubleshooting

Hi,
I have got my S3 updated to 4.1.2 a week back.
I am getting a Newtork Failure prompt frequently on my S3 as soon as I get connected to my 2G mobile data. I have not connected to any WI-FI networks, and even I have not checked the option of "Auto Update".
This problem appears as soon as I enable the mobile data. And I don't see any option where only during WI-FI I can enable the Check for updates.
This is interrupting me while doing some day-to-day tasks like while sending mail using Gmail, while browsing gallery(locked by AppLock), this network failure prompts. Due to this I need to enter the passcode again and again.
I want to stop this prompt being shown frequently. Please suggest!!
Thanks.

Try the usual solutions, as per other similar posts, first try factory reset then flash stock rom via odin - including the right modem for your country.

HSDPA works but calls/sms? Not Registered on Network

So my phone has been having the freezing problem.
Sent back for repair twice, of course came back without any fix as intermittent :laugh:
Anyway, over the last few days the freezing seems to have resolved.
The problem is now, since the 2nd 'fix', the S3 can't make/receive any calls/texts!
Mobile internet works fine
Attempted ARIZA patch, patched but problem still remains
Try manual selection - states 'unable to connect - try later'
Status shows network as 'O2 UK' correct
Mobile network type: HSDPA
Service State: Out of Service
What is going on here? Anybody got any ideas? How can I check if it's the EFS? If it is, what can be done?
Many thanks for any help!

try flash stock rom again

[Q] Problem connecting to network after aborted root

Hi I'm looking for help with my i9300. I had an aborted root, the phone froze during root and eventually I had to restart, I was able to re-install the stock ROM and the phone seems to work fine, apart from one major problem: It won't recognise any mobile networks. The phone won't recognise my network (3), or simcards from any other network. I have re-entered the APN information manually, but this has made no difference.
All other aspects of the device work fine, wifi, apps etc.
I'd appreciate any advice on steps I can take to resolve this.
I have obviously tried standard stuff such as full factory reset.
The phone still displays coverage bars as if it was connected to a network, but when I try to dial out or send messages I get an error message "unable to register on network"
Check the imei number matches the one under the battery, if it has changed then you have major problems without a backup of the efs partition. Search and read for hundreds of similar threads, there is a sticky in the general forum.

network problem in my moto g2

Recently i have flashed my moto g2(XT1068) with resurection remix custom rom and i don't know for some weird reason my phone is not receiving any network. I have cheked my phone's imei number it is there and not wiped during the flashing process. My phone detects the sim perfectly but only problem is that my device shows "no service", when i try to select mobile network manually from sim management, it shows "error while seaeching the network" and when i select automatic select mobile network it shows "registered on network" without taking any second to search. My phone keeps showing "no service" in the network section. I have already tried flashing stock rom but it did't work, now You guys are my last hope. please reply to my problem. Hope you have number of possible solution!!!!

No data connection on H930DS on the 3 network, UK after reflashing Stock pie

I can't get the data connection to work at all, and it won't even connect to a 4g network even when the signal is strong. Mine is a H930DS (Joan?)
I just reinstalled the stock pie using "H93031a_00_OPEN_EU_OP_1105.zip", I installed in TWRP. I followed the instructions on the first page of this thread .....
I have tried various custom roms on this phone but this stock pie is one of the very few that even recognizes the sim card. I settled on stock pie inspite of the bloatware.
The problem happens when the rom is brand new, before ANYTHING is disabled or removed.
When I choose to search for a Network Operator (using the 3 Network sim) I get a "3 RAT-4G" and a "3 RAT-3G" listed and it will never connect to the 4G if I choose that one. It will only connect to the 3G. Even when the signal is very strong (5 bars). When I opt to connect to the 3G network then I get a stronger signal if I choose "GSM/WCDMA auto" in "settings>>network>>mobile netwroks>>network mode" but still no data connection
THESE DIDN'T HELP
1 - using ADB and restarting the phone in bootloader. It was to reset the modem I think. There was a series of 3 commands to follow. i can't remember the details of this method but I think one of the commands included "fastboot erase modemst2". I tried it and I was getting the same error message that other people reported and it didn't go anywhere.
2 - The following solution didn't work either..............
"re-loading IMS settings using the LG Hidden menu: Dial *#546368#*930# using the stock dialer -> Field Test -> IMS Setting -> Test -> Load Preset Configuration -> Initialize Configuration. Then back out twice to Field Test -> IMS Setting -> Test -> Restart IMS process. Give it a few minutes."
3 - Resetting network settings didn't help either (Settings -> General -> Reset -> Network settings reset).
4 - Changing APN, or network bands (in settings ... choosing "LTE/GSM/WCDMA auto" or "GSM/WCDMA auto" or "WCDMA only")
5 - Changing "set preffered network type" in engineering mode settings (accessing using *#*#4636#*#*)
How can I use data connection on my H930DS?
Data modem works now!
SOLVED!
My phone has bootloader unlocked and TWRP revcovery. That's obvious I know but I only say it again in case anyone tries this with a locked bootloader and using a stock rom that has never been flashed. (I have to warn you that your results will be different, your rom will be reset for sure an your data will be wiped).
I tried so many things, flashing up and down from 8 to 10 but Stock Pie was always the least buggy for me so I persevered with that.
I think this solution reset the hardware, but I am no expert.
The solution is basically a "Factory Reset (R&D Only)". They warn you against it but with my configuration all it did was reboot the phone into recovery and then left it for me to decide what to flash or wipe, as per usual. What I only realized later, when I rebooted into system (without changing anything in TWrP) was that it had reset the hardware, or reactivate data connectivity. NowI have 3g data connection and 4g connection.
THE SOLUTION
*the following 4 lines are a direct quote (my phone's os DID NOT reset)
1) Backup everything, as the phone will be wiped. If yours is a network unlocked carrier model, make sure you have an unlock code (or unlock approval if T-Mobile).
2) Remove your Google account to disable Android Device Reset Protection.
3) Dial *#546368#*930# (replace 930 with your model number). This should open the service menu. From there SVC Menu - Factory Reset (R&D Only).
This takes quite a bit longer than normal Factory Reset. Your phone is now TRULY back to factory state.
I took out the sim and sd card before I committed to the reset. But like I said, it didn't wipe anything (maybe it would have wiped my sd card but I am not testing that). It just booted into recovery and when I rebooted into system I found that the data connection was working. Now finally it is a smartphone!
