Hi All,
I was trying to Update firmware to have market working, however I had already upgraded firmware to most recent one. And then I ended up with problems. Latter I tried fixing files manually using adb with root permissions and I ended up deleting files under system folder. I again restored files there - however now shell itself has no executable permission

. Any idea how can I get things working again? Now when I try to boot my IQ 701 - it just cannot proceed as "shell" does not have executable permissions. Even Inserting external SD card with Updated firmware cannot help - as shell does not have executable permissions. Is there any solution for this?
