but its very easy to unbrick samsung galaxy y lite duos
to do this you need to have the following
1. Stock rom packages see here... http://forum.xda-developers.com/show....php?t=2140717
2.odin from here... http://d-h.st/1TM
after downloading above files simply open odin in pc and make sure you're not going to change any default settings in it
and in the PDA simply use the stock rom which you have already downloaded from above it is in the .md5 format
connect your phone to pc make sure you're in download mode to do this simply switched off you're phone and press volumeup+power button+home
all together at the same time and when you're in the download mode plug your phone to pc via usb odin will detect your phone.
after all this click on start odin will flash your stock rom for you and notify you when its done!!!
process is very easy its happen to me a thousand times and i love flashing custom roms,kernels there many available in the site just search it.
ask anything regarding gt5302 i will definately help you.
