[myTouch 4G General] Kevinthebox:
The myTouch 4g is a good, reliable phone. When, rooted, it is even better. We happily flash ROMS away, without a care in the world. One day, however, your power button just stops working :confused:. Dread, fear, and despair right? Well there is hope! If your power button doesn't work, there are a couple of things you can do before you head for the wallet to spend big bucks on a new phone.

1. Send to HTC.

The most recommended thing to do is to check if your phone has warranty and send it in to HTC if it does. You can either call (preferable) or send in a e-mail. Remember, even if you are rooted and you send in you phone with a custom ROM, HTC will not charge you unless you remove the "VOID" sticker in the back. This is the painless, easiest method, with little effort required, *although you will have to survive without your phone for atleast a week (which was hell)

No warranty?​

If your phone is out of warranty, or if you removed the VOID sticker for whatever reason and Dont feel like paying HTC $125 to fix it, there a couple of things you can do.

2. Jury-Rigging (self-fix method)

This method is for those that are comfortable opening up their phone and want to fix the power button for themselves.

*Tools: aluminum foil, Torx T5 screwdriver, small phillips screwdriver, safe-open pry tool.

This idea was inspired from XDA user jjbadd385 who mentioned in a thread I can't quite remember that he had turned on his phone by using aluminum foil to touch the actual power button underneath the outer casing. I recommend using this thread and video http://xdaforums.com/showthread.php?t=1591388 to safely open up the phone. Ofcourse, you wont need to dismantle the whole phone, all you need to do is remove the outer casing (black rubber thing the surrounds the edges of the phone).

Just do the First step from the guide provided

. BE CAREFUL not too lose a little spring that is located near the power button, without it your power button will feel like "its stuck", but the spring itself is

NOT necessary to turn the phone on

. You will then see your actual power button at the top of your phone. Now here comes the fun part. Using your eyes, and common sense,

cut out a small piece of aluminum foil that is about roughly the same size as the power button.

Using your hands or the pry tool,

bend the aluminum so that it comfortably fits in that little square area directly on top of the power button.

Now carefully put the rubber casing back,

be wary of the aluminum falling out of place.

It may take some patience, but it shouldn't be too difficult. If put correctly, your phone should now start up! Now your power button should work whenever you click it :D

***If for some reason it doesn't, there could be a problem with the actual ribbon itself (which would be unfixable unless u bought a new ribbon), but most likely the aluminum foil probably was not placed right or was moved putting the casing back on.

****If enough people request, I'll probably make of video/picture slides of the Jury-Rigging method, but right now I have to study for my Sociology test and I'm too lazy :p

Want to turn on your phone, but you don't have the tools for the Jury-rigging method and you need your phone NOW?​

If you are UNROOTED: (this method is untested by me)

From doing a quick google search, there have been people who have turned on their myTouch 4g by simply connecting the phone to the charger and immediately holding the HOME button for about 5-10 seconds. Some have had success with this, but personally, It has not worked for me.

If you are ROOTED and your phone has these things:

Clockworkmod Recovery 5

ADB debugging enabled

You must have adb debugging already enabled on your phone or else this will not work! Even though the phone is powered off, commands somehow still go to the phone!

Make sure to set up ADB on your computer (there are multiple guides in XDA)

-Then simply connect your phone to your computer, open your terminal. Check to see if your computer reads your device by running this command:

adb devices

If your computer reads it, then you'll be all set!

Then, run the command:

adb reboot

Give me lifeee! Your phone should then reboot!
