I switched off my jailbroken iPad 1 at 4.2.1 the other day and since then the screen stays black. I can still ssh to it, can use it with iTunes, can build and run new Apps with XCode. So it looks like it is alive but the screen does not turn on. I tried to restart it (by holding both the Power and Home button for 10 seconds). It restarts nicely but the screen is - again - just black. When I press the Power button and try to move the (of course not visible) slider nothing happens either. So for me it looks like the whole Display and Touchscreen is dead.
Currently I try to drain the iPad battery so that the whole system gets shut off due to lack of power but I fear that this does not bring the Display back to life either.
Does anyone have an idea how to bring the Display back to life? I can not re-install the iOS because I have no SHSH's for 4.2.1 and I need this version because it is the last version which allows me to use XCode debugging via WiFi. And I can obviously not send it to Apple for repair because they will definitively not leave my jailbroken 4.2.1 on the device but would probably replace it with the latest iOS version which I cannot use for WiFi debugging
Any suggestions what I can try here?
