- Hold power button and home button down together for 30 seconds until it reboots.
- Sounds like a damaged battery.
- make sure date and time and set corretly
- I have done many s2 s3 note phone screens and have yet to date [knock on wood] have never damaged a screen or a flex cable. This is a doable repair if you are careful. I make alot of money doing these every week.
- You have to remove the battery and heat the screen up to a uniform temperature of 160-180 degrees F. with a heat gun. Using a dental spatula or iopener gently start to lift the glass off of the frame. Never press down always using upward pressure. Be very careful not to scratch the plastic digitizer.Use extremely light pressure when lifting. As the separation starts you will see the loca turn loose from the digitizer. Pay extra attention to the areas around the button so not to tear the flex cables. Clean the old tape off completely and replace with new. Clean glass well and wipe off any dust. Make sure when applying the adhesive tape that the surface is perfectly clean or you will crack the new glass
- Iphone 4 cdma back is an exact fit for iphone 4s.
- I use 63/37 solder and kester 951 no clean flux. The extra flux will make a huge difference in the quality of the solder work when working with such small components. I use a tip that has a width of at least half as wide as the pad. The smaller the tip the slower the heat heat transfer rate. The tip size will determine the temperature you will need to solder. The smalller the tip the more heat you will need to melt the solder because of the slower transfer rate. It is better to have the contact last no longer than 2 secs [at 350C] with the pad to prevent damage to the circuit board. Make sure to clean the old solder off of the pad before resoldering. Adding the extra flux gives an extra bit of "wetability" it allows the solder to stick better and give flatter smoother solder joints as well as helps with bridging issues.
- The home button flex will work I have used them before. Yes, the charge port is different.
- Look for a pin broken off under the home button contacts it is part of the dock connector and is easily changed. It is a 5 dollar part. If that does not seem to be the case make sure the contacts are cleaned with alcohol and make sure the screen is all the way down tight.
- I pity the fool who has to replace the glass on the jb weld one I would charge an extra 30 dollars to remove that stuff. I use tape on both sides and have never had a problem. Never use super glue or other adhesive if you can help it.

Make sure to use plenty of flux to avoid lifting pads
