Well I've done it now. Installed a new HDD and loaded old firmware 2720. Then true loading 3810 and it came on, white screen and now cycles through white, black, white etc. left for 2 hours and still the same so not updating just bricked. CD stuck in the drive and nothing seems to bring it back, even the firmware reset.
Anyone know what to do? Have vcds though it won't communicate with it.
Need someone with the RNS tool I've heard about. Will supply beer, tea, champagne to anyone who can help me out :)
