Karbonn A21 not powering up
Before two days, i have successfully installed the custom xperia rom on Karbonn A21. Today while i was trying to increase memory by Swapper2 application, I am not sure, what exactly i have done, but after rebooting, the screen stocks at ENTRY QPST DOWNLOAD. Even could not able to enter into recovery mode.
After few restarts, now the phone is not even powering up, though the battery was more that 60%.
Should i expect any kind of help or it is the end of the Karbonn A21 ?
Any suggestion will be highly appreciated.
