factory reset

hi Is it possible to do a factory reset on a tm 800hd via remote control as i have a blank tv screen and cannot see the menu or wizard on screen. any help please?

if youre gonna do that m8, the easiest way is put an image onto a usb stick, place in receiver, turn power off, turn on a repeatedly press the power button on the receiver, the display will say miniroot, if it says starting, turn off and try again. wait for an IP address to appear, then press menu, and itll flash from usb, reset everything (except your cccam and mgcamd config files usually) and start the wizard from scratch

thanks for that, but i already have an image already installed will a reflash do anyharm?
