Motorola Droid A853 and Atrix – Fixing 3G connection issues

Motorola Droid owners reports about instability of 3G signal at specific places, commonly where there’s a high concentration of antennas.

My job is located next Paulista avenue (São Paulo – Brazil), where 3G signal is not a problem, but the connection of my Droid is not stable, alternating between Edge, 3G and no connection. Owners of Atrix share of this issue too.

I know some Atrix owners that report the same thing.

Who owns Atrix, just go to Mobile Network settings and enable “Only 3G Networks” option and done!

There isn’t such option in Motorole Droid, then how to proceed?

Simple. In the Phone dialer window, type *#*#4636#*#*, a new menu will open. Click “Phone information”:

Scroll the new window and choose “WCDMA only” in “Set preferred network type” option:

Your connection will be re-established instantly. Press “Home” button to finish.

Be sure the emulator still running, in the tab “File Explorer”, select files that you want to copy to PC and click buton “Pull a file from device” ().

Choose where to put the file.

Using MS-DOS Prompt (Windows Command Line)

We’ll not use Eclipse IDE, only the tool available in Android SDK and MS-DOS Prompt.

Open up “Android Virtual Device Manager” running “AVD Manager.exe”, available in Android SDK instalation directory.

Choose your device in the lista and click “Start”.

Wait until the emulator boot and open MS-DOS Prompt.

Type command:

<ANDROID-SDK-DIRECTORY>/platform-tools/adb devices
Replace “<ANDROID-SDK-DIRECTORY>” by path of installation of Android SDK.

A list, with attached devices, will show up:

List of devices attache

Connect the ADB to emulator using the command

<ANDROID-SDK-DIRECTORY>/platform-tools/adb connect localhost:5554
The number “5554” is the same displayed  at description “emulator-5554” and at emulator’s title bar .

The line “connected to localhost:5554” will be displayed.

Copying files from PC to emulator

To send file located in directory of your PC to emulator, all you need to do is type

<ANDROID-SDK-DIRECTORY>/platform-tools/adb push text.txt /sdcard
