Hey chandruchiyyan i too had same problem with this phone it stuck on the stick together logo and i tried couple things later i called up the manufactures i had worte them on paper the steps will be ,Switch off the handset, and press the POWER KEY and VOLUME DOWN key simultaneously until it got into Recovery/Upgrade mode and Press the HOME key to get in to the next interface and Use VOLUME key to select the function you need, such as reboot system now apply update from sdcard wipe data/factory reset, wipe cache partition, Use Volume up and Volume down to move the cursor, Then use volume down key to move the cursor to " yes-delete all user data" , press menu key to select it. Then choose reboot system now, you phone will reboot itself and that will fix it and make sure you remove the Sd card before the reset.
