Airtel universal remote setup!

Airtel brings you the magical universal remote so that you can enjoy watching TV with just one remote. While our installation team will set up the remote to work with your brand of TV, the following steps gives you an overview of making the remote learn:

There are 5 basic functions which your new Airtel remote needs to learn about your TV
1. TV Power code
2. TV Mute code
3. AV code
4. TV VOL + code
5. TV VOL – code

Step 1: Bring Airtel digital TV remote in learning mode. Press and hold ‘’OK + Numeric 2” key for 3 seconds. The LED blinks twice to indicate that your Airtel remote is ready to learn.

Step 2 : Hold the source remote and Airtel remote in front of each other ( 3cm-6m apart).

Step 3: Press & release the key (First on Airtel remote and then on Source remote) which needs to be programmed in Airtel remote.
Example: Press and release the TV Power key on both remotes and release. The Airtel remote blinks twice to indicate a successful learning of ‘TV power code’.

Step 4: Now Press & release other keys ( on both remotes simultaneously) : Mute , AV, Vol +/-.

Step 5: Press “OK” on Airtel remote to store the new information about your TV. The LED will blink twice to indicate successful transfer to knowledge from your current TV remote to the new Airtel remote.

If the Airtel remote blinks four times, it means the learning failed. Go to Step 1 again

Disclaimer:- The remote can be programmed to work with the majority of the TVs, however not all manufacturers and model numbers are supported.

Reset Airtel Digital TV remote to defaults:-

1)Press red and ok button together for 3 seconds. Red LED blinks twice.
2)Release both buttons.
3)Then press 9 8 0
4)Press ok.
Now your adtv remote is reset and can be configured again.

How to Sync an iPhone to a New Computer Without Losing Data?

By far the easiest way to sync an iPhone to a new Mac or Windows PC is to transfer all iPhone files and backups from the old computer to the new one. The necessary data is stored in several different locations, and we’ll cover what files and where they go for both Mac OS X and Windows.

A few quick notes:

  • If you only want to sync and not worry about content, the /MobileSync/Backup/ directory is all you need to copy over
  • If you want to painlessly sync music and video, you will need to transfer over the potentially large iTunes folder
  • Using a local network is the generally quickest way to move the necessary files over, but copying them to a USB drive, DVD, hard drive, etc, is fine too

This guide is aimed for iPhone users, but this would work with an iPad or iPod touch too.

Syncing an iPhone with a New Mac by Copying Sync Data

  1. Quit iTunes on both Macs and disconnect the iPhone from both Macs
  2. Open the Home folder and copy the iTunes directory from the old computer to the new one, located at:
  3. Now open the user library directory and copy the backups from the old computer to the new one, located at:
    ~/Library/Application Support/MobileSync/
  4. To be certain everything is in order, copy over iTunes Preferences files as well:
  5. Now connect the iPhone to the new Mac, launch iTunes, confirm that everything is in order, and authorize the new computer

You should be able to even sync from an old PC or a Mac to a new PC/Mac if you use sharing between Mac and Windows to copy the iTunes and Backup folders and put them in their appropriate places.

Syncing an iPhone with a New Windows PC
The instructions are basically the same as above, but the files and folders you are looking to copy are in different locations. For Windows 7 users, you’ll want to copy the following directories and their contents from the old PC to the new PC:

C:\Users\USERNAME\AppData\Roaming\Apple Computer\MobileSync\
C:\Users\USERNAME\AppData\Roaming\Apple Computer\Preferences\

Replace “USERNAME” with the users account name, obviously. Older versions of Windows have iPhone backups located at the following location instead:

C:\Documents and Settings\USER\Application Data\Apple Computer\MobileSync\Backup

Now launch iTunes and connect the iPhone and it should sync as normal. Go ahead and authorize iTunes with the new computer as well.

How to slove issues with worng artwork or missing artwork on your iPhone, iPad & iPod Touch?

Issues with wrong artwork or missing artwork on your iPhone, iPad & iPod Touch? Deleted all your music and re-added only to see the problem get worse? Factory reset only to discover issue is still there? DON’T RESET!

Using this method you will have to manipulate some system files on the iPhone and also delete all your music from it.

I believe the issue lies within iTunes tagging/referencing of artwork in your iTunes library. You will need to MANUALLY assign artwork from now on instead of allowing iTunes to automatically lookup artwork (actually embedding the image to each mp3 file). This is key to solving this issue and preventing future occurrences. iTunes will lookup and download appropriate artwork; however, it will not physically add the artwork to your mp3 file. This is a set up for disaster when one mp3 cross reference leads to another mp3′s artwork due to differences in library databases…


1. Plug in your iPhone and delete all music & videos off your iPhone. Turn off auto sync music in iTunes (make sure to select “Manually manage music and videos”). Disconnect iPhone from iTunes.

2. From within iTunes, CLEAR ALL iTunes assigned artwork from all non-iTunes purchased music. The easiest way to do this is to highlight all song in your library and right click and select “Clear Downloaded Artwork” (after this I would double check all the albums assigned by iTunes have been cleared).

3. Close or Quit iTunes.

4. Now we need to make sure iTunes will never be able to reference artwork from its personal database. On your computer, delete download & iTunes purchases folders from following path: /user/music/itunes/album artwork/

5. Download, install or run from the following any one of the software iTools, iExplorer or Diskaid.

6. Plug in iPhone. Make sure you’ve quit the Music App from multitasking. Open iTools and then open “Raw File System/iTunes_Control

7. Just in case, highlight every folder in this window (Artwork, Device, Music, etc) and select “Copy To Mac” or “Copy To PC” in order to create a backup in case something goes worng.

8. Navigate to “iTunes_Control/Artwork” folder and delete “ArtworkDB” file.

9. Navigate back to “iTunes_Control” and now access “Music” and delete everything in this folder.

10. Now navigate to the “iTunes_Control/iTunes” folder–delete all the contents of “Artwork” (different folder from step 8).

11. Navigate to the “iTunes_Control/iTunes” folder and delete every file starting with “Medialibrary.***

12. Exit out of everything, unplug your iPhone. Restart your iPhone by holding the power/hold and home button until you see the Apple logo.

13. Open iTunes and plug in your freshly restarted iPhone. At this point you should have no music & videos on your iPhone. Since you’ve cleared all your downloaded album artwork, you’ll need to manually add artwork to your music (make sure the images are embedded into the file). Now manually add music to your iPhone. Launch your Music App. If the album art is correct you can manage your music however you want.

Thanks! This should have solved the issue of corrupted album artwork! For future reference, DO NOT let iTunes lookup artwork for you–always manually add artwork yourself!

How to Fix “iTunes cannot read the contents of the iPhone, iPad or iPod Touch”?

When running iTunes and you receive the popup message:

"iTunes cannot read the contents of the iPhone. Go to the summary tab in iPhone preferences and click restore to restore this iPhone to factory settings”.


  • It could be one of two (or both) files are corrupt on your iPhone (or other iDevice), they are iTunesDB and iTunesCDB.
  • There is an fast fix for this, even if your iDevice is non jailbroken.
  • You want to disconnect your iDevice from your computer and close iTunes to ensure you DO NOT RESTORE.
  • Download iFunBox or iTools a Free Tool for accessing the iDevice file system. It has both a OSX version and Windows version for download.
  • After you download the version of iFunBox or iTools for your OS, you will need to install it and run it.
  • After installing and running iFunBox or iTools, connect your iDevice to your computer.
  • You will see a message in the Upper Right of iFunBox “connecting to iDevice“, after iFunbox has connected to your iDevice, click on the tab “iFunbox Classic“.
  • On the left panel, expand “Raw File System” (click on the +), then expand “iTunes_Control“, then click on “iTunes“.
  • In the right panel you will see a number of files, right-click on the file “iTunesCDB” and select rename, please add X after the iTunesCDB in the file name, this will allow you keep the file in case you need it again (you should never need it, but better to be careful than sorry.)
  • After you have renamed the file, click on your iDevice name on the upper right of iFunBox and select “Device Safe Removal“, this will ensure the file name change will be written back to your iDevice.
  • After you see your iDevice is closed (“No device connected” will be displayed in the upper right), you should now close iFunBox

Now run Apple iTunes, it will see your iDevice and you will be able to Sync again.

How to Unpack Files From the i386 Folder on an XP Installation CD?

If you have ever added or removed Windows features in Add/Remove Programs or installed new hardware, your Windows XP computer may have prompted you for the Windows XP installation disc and the contents of the i386 folder. Unpacking the complete i386 folder to your hard disk can eliminate the need to insert the Windows XP installation disc when prompted. It is also required if you have an older version of the Windows XP installation disc and wish to “slipstream” it with newer Service Packs, such as Service Pack 2 or 3.


1. Copy Entire Folder:

  • Insert your Windows XP installation disc.
  • Click on “Start,” then “Run.” Type “command” and press “Enter.”
  • Type “mkdir c:\i386” and press the “Enter” key. (You can save the contents to another hard disk. Change the directory letter from “c:” to the correct hard disk letter if you save to another drive.)
  • Type “cd c:\i386” and press “Enter.”
  • Type “xcopy d:\i386 /s/h” and press the “Enter” key. Change the optical drive letter from “d:” to your computer’s optical drive letter if it is not the D: drive.

2. Unpack Specific Files:

  • Insert your Windows XP installation disc.
  • Click on “Start,” then “Run.” Type “command” and press “Enter.”
  • Type “mkdir c:\bckup” and press “Enter.” (You can create a folder with any name except for one that shares a Windows folder name.)
  • Type “expand d:\i386\filename.ext c:\bckup” (replacing “filename.ext” with the specific file name and extension of the file) and press the “Enter” key. Change the directory where you wish to extract the file if you are replacing a system file.

Repeat for each file you wish to extract.
