If you have a new Samsung Galaxy Tab 10.1 wifi or 3g (P7500/P7510) and you try to flash CM9 ICS recovery you get a rolling recovery screen, something like below.

If you go back to HC 3.2 with flashing a new ROM via ODIN and want to go to ICS again you have the same problem, so with pershoot I found a shorter way of fixing this by just flashing the bootloader of the ROM that was mention in the xda post. See screen-shot below.
Download bootloader here. md5sum [fdcb71be2a0f95bed751b4bbb63c6b58 bootloader.tar.md5]
- Download bootloader.
- Start Odin
- Select BOOTLOADER and choose downloaded file
- Put tab in download mode (press power+ vol down, vol up to select download mode)
- Connect tab to PC with USB cable
- Press Start.
- Tab should restart itself.
