I have a smart phone (Karbonn A50,Android version 2.3.6) which was rooted earlier.

While accessing my files on the memory card, I came to know that I can access the system files and apps:think OS. I've selected all the files and tapped to delete them and got a warning not to delete. On repeated trying, I was able to delete them to some extent and the device got stuck.

Then I removed battery and switched it on. Nothings works. The phone gets stuck on boot logo (karbon smart) and if try to switch it off it doesn't, until I remove the battery.

If connect to PC, it notifies that something has been detected but no device is seen in my computer. I can't access factory reset either.

Please help me.

  • hmm :( please do help man

You mean you deleted Files from /SYSTEM/ folder.

If yes then Bro you did a big mistake. Your device got corrupted.To recover Download android ROM for your device from internet then go to download mode and flash it using ODIN .

  1. You can download ROM from LINK: http://androidxda.com/download-karbonn-stock-rom-models

  2. Download ODIN from http://odindownload.com/ (Requires PC)

    I would NOT recommend downloading odin from that site. There are plenty of posts and etc on XDA saying that site packages viruses and malware with odin. forum.xda-developers.com/showthread.php?t=2712008&page=2 You can find plenty of legit links on XDA for odin.
