General :: Infuse 4G No Network Connection / IMEI As Symbols / EFS Unfound?

Jan 1, 2013

My problem, I have a Samsung Infuse 4g with gingerbread which I installed through Odin with all the info I gathered reading post here. When the problem occurred of no network access, the phone had the stock froyo firmware and that had been working very well until now.

I cannot get data at all. I can get on wifi, send calls and text messages. I tried changing the mobile network access points and nothing. One thing that I did notice after reading all your post, was that my IMEI is a bunch of symbols, diamonds, question marks, etc.. but is not numbers like it should. The issue started with the stock firmware (froyo) and continues with GB. Another thing is that I have never backup the system at all, I currently cannot find an EFS folder, even after installing RootExplorer.

I dont put all kinds of fancy utilities on the phone, the only one there is Golf app. This just happened out of nowhere. The phone is not even a year old which I got from ATT. You can say, send back to ATT for warranty! I am a Soldier stationed in Germany, because my account with ATT is suspended until my return to the US, the warranty does not cover the phone. In the end I am screwed anyway since I changed the firmware to GB and it is rooted. My questions are;

1. Is it possible that I dont have an EFS folder?

2. The lack of EFS folder constitutes to an unreadable IMEI?

3. What can I do to fix it? Is there a dummy guide to fix this?

Android :: Android To Open Network Connection On Specified Network Interface - Network Type

Mar 6, 2009

I have been looking at the ConnectivityManager class documented at .

I would like to know if an Android application can open a network connection (socket) on a specified network interface [on a device supporting multiple network interface types WiFi, Cellular, WiMax etc] ? I am looking for the capability for an application to open a socket on a given type of network for example over WiFi network or over 3G Cellular Data network.

If this is possible in Android, how would I code this requirement within the API Framework ? The ConnectivityManager enables an application to learn about available network connections and currently categorises them as either TYPE_WIFI or TYPE_MOBILE.

There is a member function in the ConnectivityManager class called requestRouteToHost(int,int) [url] which "Ensure that a network route exists to deliver traffic to the specified host via the specified network interface. An attempt to add a route that already exists is ignored, but treated as successful." Sounds like this would install an IP routing table entry to reach a given host via a specified network interface type (WiFi or Mobile). After calling this would it be sufficient for an application to open a socket and connect to the desired destination address ?

Or perhaps the application needs to bind() a socket to a local address of a network interface of the desired type (WiFi or Mobile) Or by setting a socket-level socket option of SO_DONTROUTE ?

General :: T-Mobile Galaxy Vibrant - No Network Phone Connection?

May 31, 2013

I have a T-Mobile Galaxy Vibrant that was running Android 2.1. I rooted the phone (successfully), and installed Slim Bean 4.2.2 plus Google apps. Everything was going smoothly and I was reinstalling apps and data when I noticed that I had no network phone connection. Slim Beam did not seem to recognize the sim, and I came up empty searching for networks. I removed the sim and put it in another phone, and everything was fine.

I decided to restore the previous android 2.1 (which I had backed up) using ClockWorkMod Recovery. I did restore, then reboot. Now the only thing I get is the initial screen ... Vibrant and Samsung in bold white letters. I have tried repeatedly to launch CWM Recovery, without success.

General :: No Network Timeout When Connection Lost On Device But Works In Emulator

Feb 14, 2013

I'm developing an App that sends keep-alive packets to its server to ensure the connection is still alive.

The server is java based and thus easily to run. I run the server on a virtual machine (Windows 7). After my App is connected and the first keep-alive packet is received (it displays a message in its console output) I disable the network interface in Windows. This step is very important because by disabling it, there is no way to send any packet back to the client informing it about network changes.

The clients are configured to send every 25 seconds a keep-alive packet, so you don't need to wait long.

When you use the sample JavaClient on Windows 7 it takes less than a minute after the keep-Alive packet and an exception is thrown which triggers reconnection (which currently can't occur). This is the expected behaviour.

When you use the sample Android App on an emulator (tested Android version 2 and 4) it is the same behaviour. So in less than a minute after the keep-alive packet it recognises that the connection is dead, throws an exception, this triggers reconnection.

Problem is now when this App runs on a real device (tested several, Xpearia Arc S, one Cyanogen Mod 4 on Galaxy S3 and my Galaxy S3). I've waited 5 minutes, but there was no exception. This behaviour is reproducable.

Since this is a sample App, it uses no wakelock or service, so to test it is important to have it in foreground all the time (don't switch to other Apps or homescreen) and increase your display timeout to a few minutes to ensure that it doesn't go off. Use Logcat-Output to get informed whats happening, because there is no output in the App itself.

Now Sample-Code is in the attachement. Something had gone wrong. The Code consists of 3 Eclipse projects which you can easily import.

General :: Install Ubuntu On Infuse 4G?

Mar 3, 2012

I am attempting to install Ubuntu on my rooted Samsung Infuse 4G. I have consulted several how-to articles here and elsewhere, but after several hours of work I am still stuck on the final lines of code in the terminal emulator app that a YouTube tutorial suggested. Below is the code that I have entered thus far, and the error code at the bottom of the list:

Ubuntu Chroot Bootloader v0.1
Ubuntu Bootloader is now installed!
This process does NOT damage Android OS!


I have tried two different installation methods. The first one focused on accessing the advanced shell through Windows Command Prompt. This didn't work because the prompt froze after I typed in "advanced shell" (several attempts brought same results) .

I then tried the "easy" version that involved the terminal emulator app in the place of the command prompt. Assumedly, if I can resolve this last issue without causing any more, I should be able to access Ubuntu through Android VNC. It may be important to note that the time before last when I typed in the above code, I got a different error code. That error read: losetup: /dev/loop1: no such device or address. I don't know what made it change.

General :: Infuse 4G (SGH-i997) Stuck At Samsung Screen

Jun 11, 2013

I rooted my device with superoneclick, got the 3e recovery, then got the CWM recovery for galaxyS i9000 through ROM manager(working fine), and then rebooted into recovery and flashed carbonROM for 4.2.2 (the .zip file), along with Gapps for 4.2.2. Now it's stuck at the samsung screen, I can't boot into recovery, taking out the battery doesn't work, and the power button is NOT jammed. I can't restore the backup that I made because I can't go into recovery and my computer is not detecting the device (with all the proper drivers installed).

I don't care about the user data (including contacts, messages, etc) that much, if it needs to be wiped. I only want my phone back, with or without the ROM.

General :: Spam SMS Containing Random Symbols?

Apr 8, 2012

About four-five days ago I've began receiving text messages from the number "9999999999".(I'm aware it's not a real number) The texts always contain random symbols, no actual words. It's not a foreign language, it's honestly pure symbols. They had hit the 100mark as of yesterday. 100 text messages received from this nut. I receive them at all times of the day and my number is on the do not call list. (not sure if that applies to texting, but yeah..)

I did not reply to them until yesterday where I sent stop, end, #, etc in attempt to end the madness. I've also blocked the number "9999999999" using my phone providers websites. All my attempts to prevent the texts have failed. I still get them from the same 999 number.

Example of such text is

"� `P �� € 13 ƒƒcK �K{q{�s!s� skk™kk+›› ;( |$o��$d � +�r33q��3;R�
)ƒ� lŒH� Y‰� �ɡ�‘ � z��‚)�‚bjp 4T p
�l@, DŽ C�� �y{kk›"

While doing a google search that contained a small portion of a text I've received, THESE are the result. Broken webpages with the same symbols I receive just in a different order. I want two things to be honest... A method to stopping this and to know what the text is written in so maybe I could decode it and find out what each text says. I want them both equally the same.

General :: App For Extra Symbols On Facebook?

Apr 22, 2014

When I use Facebook or even Instagram, I noticed people use these special symbols in the comments or in their status update.

So finally, I decided to ask my friend how they did it.

They told me iPhone already comes with it in their keyboard.

Unfortunately, there's none for the Android built in.

So I did a search on the Google Play and found out there's tons apps that can do it.

I have Samsung S3 so I just wondering which app is the best one to install on my phone that is free?

General :: CM 10.3 Default Lockscreen Symbols?

Oct 15, 2013

I just flashed the newest CyanogenMod 10.2-ROM ( and accidentally changed one of the lockscreen symbols. Well actually I was just curious of what I can do with the new ROM.

However, after realising I had changed on symbol, I hit the reset button in the upper right corner. It did not restore the default, white symbols, but instead removed the remaining two default symbols, leaving me with the white padlock. Now my question: how do I restore the default symbols, without a factory reset?

Solution: you can change the symbol independently from the started app by pressing on it a few seconds while choosing its position on the lockscreen.

HTC Desire :: Network Connection Problems

Nov 15, 2010

Recently I've started facing a problem on my Desire. Sometimes it acts like the network is down, and the signal bar shows a cross. At that time when I tried another sim card, the network was working fine. Then after a while my phone starts showing network with the original sim. But it won't connect to the internet. It simply won't connect, although I am toggling the mobile data connection tick mark.

Right now the network has gone again, and I'm trying to get connected to it through either Automatic registration or manually selecting from the list of network providers. But I get the message "unable to connect to this network at this time"...

HTC Desire :: Launcher Pro And Network Connection

Oct 26, 2010

To android 4 months ago and running an Unrooted Desire Android 2.2 on O2 (OTA update to froyo went no problem) No Taskiller

Must say I'm loving android, for the sheer ability to customise it, altough not brave enough to root yet!
Installed folder organiser and launcher pro plus cos I want to change icons and names of folders etc.

My problem is when I switch from sense to laucher pro, i lose my data connection widget/ shortcut and cant get it back. On my sense screen I have the power control widget, which gives me the wifi connection toggle and also a mobile web toggle. I want a mobile web toggle that works with launcher pro.

Downloaded the widgets pack from curvefish, but the APN on/off does nothing at all.
