Got my tab as free device with new line, not planning to use it with service at all, so upgrading to ICS would be a nice change.
SCH-i800, Firmware 2.3.5, Kernel 2.6.35.7, Hardware I800.0.3
Tried latest one click - didnt work, dies on step7
Tried DooMLoRD_v4_ROOT-zergRush-busybox-su.zip - didnt work:
[-] Zerglings did not leave interesting stuff
--- WAITING FOR DEVICE TO RECONNECT
if it gets stuck over here for a long time then try:
disconnect usb cable and reconnect it
toggle "USB DEBUGGING" (first disable it then enable it)

Press any key to continue . . .
z4 doesnt work either - after clicking on permanent root, it exists after 15 or so seconds, and the tablet becomes very slow until reboot.
