I have an Android phone that isn't starting up. All it shows when I power it on is the boot up screen. The recovery mode does not start and the ADB shell on my laptop fails to detect the device as well. What can I possibly do to get my device running again. I don't mind formatting the phone. The device is a Karbonn Titanium S1. Any help would be greatly appreciated. Updated: - The adb devices command detects the device as long as it is switched off and connected to the PC via USB. - adb shell -> recovery --wipe_data gives a segmentation fault '139' error. - Trying to boot the phone at times ends up in a screen that says: > **Encryption unsuccessful** > > Encryption was interrupted and can't complete. As a result, the data > on your tablet is no longer accessible. > > To resume using your tablet, you must perform a factory reset. When > you set up your tablet after the reset, you'll have an opportunity to > restore any data that was backed up to your Google Account. - The phone does not boot into recovery mode the manual way but does enter a frozen recovery mode when I run the adb reboot recovery command with an "data mounted failed" error.

My new Christmas present is straight out the box... It's my first touch screen mobile. I've put in my SIM and copied some of the contacts. That's it, that's all I've done. I get my first incoming call and I can't answer it - I'm tapping everywhere on the screen. I had to call the caller back once the ringing timed out. I've read through the quick start user manual but there is no mention there. How do I answer the call?

I don't have an SD-card as I got my Karbonn Smart A10 Dual SIM Android based on Android Jelly Bean v4.1 and 1 Ghz Dual Core processor out-the-box. There are two things which appear to need an SD-card: 1 - camera: when I select camera, I get "No Storage - please insert an SD card" 2 - whatsapp: when I download and install whatsapp, I get "Error - application cannot be installed in the default install location." Is there no work-around? Is the best solution for me to run off and buy an SD card?
