In general, once they ask to be connected to iTunes, you've pretty much got to connect it to iTunes.

Be sure the area the screen adheres to is clean before you glue it down. Also if any of the case is bent you may need to use some small pliers to reshape it before the screen will lay flat.

In general I apply flux as soon as I begin to apply heat, unless using a preheater in which case I wait a few minutes while it warms up.

I've used LocTite to do this in a pinch before. Just be Very sparing and careful. Also be sure to clean any surfaces thoroughly before application.

Motorola phones can do this when they have a problem with their bootloader or software files. It should be possible to load into FastBoot mode to re-flash the phone's ROM and hopefully resolve the issue. This is a fairly in-depth process. Before getting into it, make sure the phone will actually boot and run in FastBoot. To do this, turn the phone off, then hold the Vol+, Vol- and power buttons all at the same time until a white screen appears, then release. This should bring you to FastBoot. If the phone doesn't reset here, then I would suggest proceeding with flashing a ROM. For this, I direct you to an existing Motorola Droid RAZR FastBoot guide. I hope this works for you, I've used this method on other Motorola phones such as the Atrix 2 and the Bionic. If nothing else, it's easier to try this than to replace the phone.

I would suggest removing the battery for a few minutes. It's not the most difficult thing to get to. Motorola Droid RAZR Battery Replacement You don't need to actually remove the battery, just unplug the terminal for a few minutes.

You should be able to use the standard Nintendo RCA cables (such as used by the Wii and also the SNES). If you get no video when using this the problem may lie with the console or possibly the game. Any dust or wear on the contacts will cause the system to give no video output at all.

On the N64, if the game cart isn't communicating with the console you simply get no display, it is as though you haven't even turned on the unit. Quick things to try would be another game in the console, if this doesn't work try using a fingernail file in the console game slot to quickly clean off the connections (you can also insert and remove the cartridge repeatedly in quick succession) and then try to turn on the console. If this works then you need to replace the internal game connection slot or at very least give it a thorough cleaning with alcohol and some cotton swabs, the more thorough you are the better the result.
