Sorry you are having trouble, but you included absolutely no information that could be helpful for pointing you in the right direction. We don't know:
Your phone
What update it's on
What recovery you are using
What roms you have tried
Without that info, no one would have a clue on how to help you.
Information
My mobile is " Peace mobile "
it is having android 4.0.4 ICS
I Want to install a new ROM because some files in " FILE SYSTEM ROOT " are deleted by mistake
i cannot power it on . I only have access in recovery mode and factory mode , from there only i can update , i do not have access in the mobile i have also posted earlier about this " FILE SYSTEM ROOT" problem 50+ reviews but no reply.
you can see to it here : " http://forum.xda-developers.com/android/help/deleted-file-root-ect-vendor-t2928314 "
plzz help if you could .
or if there is no solution please let me know .
But please don't ignore .
