I performed this using a PC running Windows XP SP2.
WHAT YOU NEED
A PC, USB cable to connect phone to PC, driver , CMW and Busybox files.
Of the 100s of posts at the xda-developers forum the one post that had all the required info was this : http://forum.xda-developers.com/showpost.php?p=30416357&postcount=114
The post has a link to a single compressed RAR file that has all the required files packed neatly. The poster, probably too geeky to be able to speak directly to us laypeople, offers an incomprehensible description of the method.
But, for instructions and pictures read the text in this post ( http://forum.xda-developers.com/showpost.php?p=29149445&postcount=2, http://forum.xda-developers.com/showpost.php?p=29300082&postcount=12 ) (instructions are still too geeky for me, but pix are self explanatory) . The images there are for the Karbonn A7, but the same routine applies to the A5. The files though are not complete, so get the files from the earlier post.
The file is a RAR file, and you must unRAR (use 7zip for the job) it before proceeding. The package contains 3 folders - Driver, ROOT, S01_Recovery.
STEP 1 : INSTALLING DRIVERS
Even if you don't root the phone,you will find the drivers quite handy. With the drivers, you will be able to
1. Use the phone as a modem to connect to the net through a laptop/PC. Called USB tethering.
2. Be able to access the micro SD card in the phone and transfer data.
Drivers need to be installed manually, some of the disadvantages of buying cheap phones, I guess.
a. First switch on the USB Debugging mode in the Phone. For this go to Settings -> Applications - >Development-> USB Debugging.
b. Then connect the phone to the PC with the USB cable. The Sytem will detect the new device as "Tianyu <the rest doesn't matter>"
c. A pop up will ask for Auto or Advanced installation of drivers. Choose Advanced. Then browse to the unRARed Driver folder and click on OK.
If I recall right, atleast 4 (maybe 5)devices are to be installed, so the above process of manual installation has to be done as many times.
One of the drivers is the ADB driver that is crucial for rooting. Even if this driver is not installed, the Modem driver and Mass Storage drivers will let you use the phone as a modem and transfer files to the micro SD card in the phone, respectively - which is a small consolation.
If you don't see the installed ADB drivers in Device Manager (as shown in the pic below), chances are USB debugging has not been activated - do that and retry. Worse, sometimes the driver is not installed because there is a conflict in the PC (which happened in my case). You can try to rectify this conflict in the PC or, since the conflict is not the main issue, you can just retry the installation on another PC (which is what I did).
STEP 2. TRANSFERRING FILES TO SD CARD
With the Mass storage drivers installed, you will now see the phone's micro SD under MY Computer. Copy the SU-Busybox-Installer.zip file to the card. You can copy it anywhere in the card, just remember the path.
STEP 3. LAUNCH PHONE IN FASTBOOT MODE
This is simple: switch off the phone, press the Volume Up button and then press the Power Up button - while the Volume Up remains depressed. Keep them pressed till the phone screen is turned green (about 10 seconds), and immediately release the buttons. If this is tricky, an easier way is to reboot the phone, and keep the Vol UP button pressed while the phone powers up.
The Green screen confirms that the Phone is in FASTBOOT mode.Check images here : http://forum.xda-developers.com/showpost.php?p=29149445&postcount=2
STEP 4. INSTALL CWM
One of the unRARed folders is S01_RECOVERY. In there you will find the CWM_RECOVERY.BAT file. Run it. A green window with a command prompt will pop up. Press Enter at the first screen and the second screen (please feel free to read the text displayed...). If your phone is connected and ADB drivers are installed, the phone is detected by the program and you can press Enter for the CWM installation to proceed. The windows turns RED as this happens. This takes a couple of seconds, after which the phone reboots and the CWM windows reverts to green. You can close the CMW window after this.
If the phone is not detected, the screen will remain RED. This means that the ADB drivers are not properly installed. Try installing it on another PC or gear up for Method 2 ROOT process.
To make this guide idiot proof : make sure that the phone is plugged in if the screen stays RED, and then press ENTER after the phone is detected.

STEP 5. LAUNCH PHONE IN RECOVERY MODE
With step 4 over, you are on the home stretch. You no longer need the PC.
To use CWM, you need to get the phone in it's RECOVERY phone. Here the process is similar to getting the phone into the FASTBOOT mode, except that you need to keep the Vol Up and Power keys depressed about 5 seconds more after the green screen appears. The screen next turns RED, which indicates that the phone is in RECOVERY mode. Release keys once this occurs.

6. INSTALLING BUSYBOX AKA ROOTING THE PHONE
In the CWM Recovery menu, you will see much more options that seen in the normal phone (err... if you had checked out them before installing CWM!). One of them is the option to "Install Zip from SD card". You can scroll through the menu list by using the Vol up and down keys and select with the Power button. Select this option, then browse to the SU-BUSYBOX-installer.zip file which was copied earlier and select it. A few logical menu options need to be made, and a few seconds later... you have successfully ROOTED the phone. You can now reboot the phone.

POST ROOT
The first thing I did after rooting the phone was to install "ROOT Uninstaller" app. This app, besides performing uninstallation of system apps (like Youtube), allows backing up and restoring apps to / from SD card, so I don't need to go online to Google Play store to reinstall any of the apps that I have downloaded. This backing up /restoring came in handy when I removed the default dialer (as I already has Dialer EX for the job) and found that the phone couldn't work without it! A quick restore and reboot solved the problem.
PRECAUTIONS
POWER
While the time taken to do the steps is under a minute, it is best to ensure that there is enough battery to power the phone through the process. Keeping the phone plugged into the PC while the process occurs is a good idea since the battery is charged through the USB connection. Or you can also use the phone charger for the purpose.
SYSTEM BACKUP
For this method, you need not worry about backing up since the system is not roughed up. BUT, it is still a good practice to take a backup before starting. For this you can use the Backup / Restore option in the CWM Recovery menu. The files are backed up to the micro SD card under the CLOCKWORKMOD folder, so ensure that there is adequate space.(500MB should suffice).
UNINSTALLING CWM
CWM is a very useful tool to have. But, if you want, you can revert to the default installation routine easily. In the Step 4 described above, rather than run the CWM_RECOVERY.bat file, run the STOCK_RECOVERY.bat file. That's it. The other steps remain the same.
IT HAPPENED TO ME
The process was completed smoothly once the phone drivers were properly installed.

hi I made all your proces but after the cell phone restarted, I tried to put in recovery mode, I hold the 2 buttons and when I saw the red display I release the buttons, but the cell remains in the red screen all the time and say only "recovery"
ReplyDeleteDrear can you describe with some images or any video tutorial. if any problem of your karbonn A5 check the hard reset method.
