I then tried to flash Cyanogen using CWM. I first tried to flash CWM using heimdall but also failed (error claiming interface failed). I then converted the recovery.img to .tar.md5 (7zip to tar and md5sum to md5) and flashed using Odin which went fine and was able to boot into CWM. I put both the ROM and gapps on the SDCARD and flashed from CWM but I got an error stating that (cwm failed to verify whole-file signature). I even tried to flash using adb sideload which seamed to finish 100% but when rebooting it returned the same signature error.
Please any advice. What bothers me is that I have done this many times before and never went into any issue. If I could at least make Kies connect to recover the damn thing.
PS: my GS3 is SGH-i747M and I downloaded the ROMs from sammobile and update-samsung
BTW, when I flashed CWM, the menu I got is:
reboot system now
apply update from ADB
apply update from sd card
wife data/factory setting
wipe cache partition
and there is no "Install zip from sd card"!!!
