Hi geekmaster, is there a Diags mode option to mount the root partition? (which I understand to mean mmcblkp1) I saw a menu item somewhere called Mount nfs but it didn't do anything. Otherwise I've only seen "USB device mode", which mounts /mnt/us. As you mention later on in the thread, and I can verify, approaches using data.tar.gz + don't work if you have a full /var/local - the data.tar.gz file disappears, but the script is definitely not executed (even after I pared it down to one "touch" statement) So if I can't get into the root partition, is your new jailbreak the only way forward? Or would it be worth trying a fastboot approach?
