My best advice is for dismanteling the elements of phone give the set to local service station because if by chance we dismantelled important elements the warranty will be void.. so better avoid this... hope i have helped you.

The buttons on my phone do not work ;(


For many cell phones, the buttons are the main way -- and sometimes the only way-- that you can interface with the device. Most cell phone buttons are simply small domed pieces of metal that flatten out when you press them, completing a circuit with a metal pad on the circuit board and allowing the software to register a keypress. If you need to fix buttons that have stopped working, you'll first want to try some simple fixes, but you will probably have to open up the device.

1.Remove the device's battery, wait about 20 seconds, then replace it. Software errors sometimes interfere with the keypad operation. Removing the battery will reset the software and if the buttons start working again, you will have saved yourself a lot of effort.
2.Take note of which buttons are not working. Once you have the device apart and are staring at the internal keyboard, it may be difficult to remember exactly which buttons are non-functional.
3.Remove the cell phone's plastic housing so that you can get to the keyboard. The exact method for doing this will vary widely based on your exact model of cell phone, but most will have small Phillips or Torx screws on the back side. Once you've removed the screws, use a pry tool to separate the housing and get to the keyboard.
4.Check the rubber keypad for damage. This is the part that contains the keys you actually press, the underside of which will have a small cylinder under each key. When you press down on the button, the cylinder pushes down on the actual keyboard. Any damage to the keys on the topside, or to the cylinders underneath, can cause an individual key to stop working. If there is damage, there is no way to fix it -- you will have to replace the rubber keypad.
5.Check the connector that runs from the keyboard to the rest of the circuit board to ensure that it is seated correctly and is not damaged. If it is damaged, you will have to replace the entire keyboard to restore functionality. Not every keyboard will have a cable, as some are installed directly on the control board, so don't worry if you can't find one.
6.Hold the heat gun about six inches above the keyboard. Turn on the heat gun and move it around the keyboard for about a minute. Do not hold the heat gun in any one place for more than a second or two.
7.Pry up the white sticker that sits on top of the keyboard. This sticker holds the metal domes, which are what get pressed down to actually cause a button press, in place. If the sticker is not coming up, apply heat for another 10 seconds and try again. Be careful that you do not separate the metal domes from the underside of this sticker.
8.Apply isopropyl alcohol to your brush and scrub the metal pads on the keyboard, along with any nearby components on the circuit board. Dirt, debris and moisture damage can build up on the keyboard over time and eventually cause it to stop working. Cleaning it is not a guaranteed fix, but it often helps.
9.Locate the metal domes, which are attached to the underside of the white sticker, for any individual keys that are not working. Place the tip of your small screwdriver in the middle of the concave side of the dome and pull the edge toward the screwdriver. Sometimes, the domes will lose their ability to fully depress, and this process will restore this ability. Don't pull too much -- just enough to add a slightly greater curvature to the dome. Note that this process should be used only when a single button is non-functional. If a group of buttons, or all the buttons, are non-functional, the problem is elsewhere.
10.Replace the white sticker, ensuring that the metal domes are positioned exactly over the metal pads on the circuit board. Reassemble the device and try out the keyboard. If the keys are still not working, the keyboard is probably never going to function again.

I hope you find it very helpful. Best regards.

My hinge like just poped out when i flipped it open once... its still works and it can sense when i flip it sideways or vertical... but like its hanging on by a little strand of like wire and i cant flip...


usually the mechanism is supported by spring loading. so you wont get a good result after superglue. very likely it will pop out again.

solution is to buy a new housing - i.e. phone without its circuits. and transplant your old phone to it.

Pantech MATRIX C740 slide hinge has come loose. How do you take the phone apart to fix? (Pantech Matrix and Duo are not the same phone)


i suggest not taking the phone apart. 5 of my friends and myself have the matrix and after flipping it a couple of times the hinges are always going to feel loose. they have felt that way on mine for over a year. and if you take it apart, the senor bars for the keyboard will go out and you will have to get a new phone or just use the number pad

On your flip top key pad, you can remove first the middle cover, it is clip type so no need to un scew, but just be very carefull.

after removing it, you'll see to set of screw, remove it so that you can take out the flip key pad,

turn your unit back, near the camera , there are two small cover there , remove it and you will see two screw, take it out

open the battery cover, remove the battery and sim card and the memory card, inside you will see, again two set of screw, take it out,

now all the screw has been removed

on the side oy your unit where you ca find the scroll, try to plip out the cover usig a twizzer or any pointd object, just flip the cover easily until you where able to remove the topcover completely

now just support the LCD, be very carefull so that may never damaged the flex of your screen

at the back of the screen, there are again another set of screw, remove it slowly, make sure that you supported the screen properly

How do you change the faceplate on the nextel i95?


BASIC disassembly of your phone(i60/i90/i95)
--------------------------------------------------------------------------------
This ONLY covers unscrewing the housing and splitting it open? that ALL. You'll need a T-8 torx driver for this.

Step 1: Turn you phone off, turn it over, take off your battery cover, take out your battery, and take out your SIM card. Be careful with your SIM card. Unscrew your antenna, remove it, and take out the metal antenna tube.

Step 2: Get your T-8 torx. Unscrew the THREE torx screws in the battery compartment. They are located in the bottom two corners and in the top left corner of the battery compartment.

Step 3: Peel back the right hand side of your ?Nextel? sticker just above the battery compartment. Peel it back ONLY A LITLE, until you expose the fourth torx screw. Use your T-8 torx to unscrew it.

Step 4: Carefully separate the two halves of the housing. BE CAREFUL, and keep in mind that at the top of the phone (near the flip hinge) there are cables still attached (the flip ribbon cable and the headphone jack). You will not be able to separate the two halves of the phone body all the way and will want to make sure to keep the top part of the housing relatively close together. If you screw up and damage the cables up there? don't try to blame us? we warned you.

Step 5: Do whatever it is you wanted to do that required you to split apart the housing in the first place (e.g. replace a keypad, PTT buttons, etc.), put the two halves of you phones body back together (carefully aligned) and screw the torx screws back in.

Step 6: Put your antenna, SIM, and battery back in, and you're done. Enjoy!

**Now let's talk about the flip. This ONLY covers the removal of the front and inside lenses of the flip. If you want to remove your flip completely, or remove the LCD of the i90. SEARCH the forum for info on how to do that. You'll need a T-6 torx, a SMALL flat-head screw driver, a hobby knife, and a blow-dryer for this.

Step 1: _This is optional, but is ideal for those nervous people out there who don?t want to take any chances. Remove your antenna and battery but put your battery cover back on.

Step 2: FIRST, open the flip. With the phone facing you (as if looking at your screen), look into the gap between the flip hinge and the phone body in the very center of the flip's hinge. You're going to see a small slot in there. Remember that slot? it's important.

Step 3: Close the flip and turn on your blow-dryer. Keeping the dryer about 4 inches from the surface of the front lens (the blue thing on the i95 or the silver thing on the i90) heat up the lens surface. Keep your blow-dryer moving around? DON'T concentrate it in one spot, you'll end up melting something. All you want to do is soften the glue a little. You don't need to use the dryer for too long to accomplish this. A minute or LESS should be fine, use your GOOD judgment.

Step 4: Once you have heated up the front lens enough to soften the glue underneath, quickly open the flip and use your small screw driver and poke it through that slot we talked about in step 2. You are pushing on the back-side of the front lens when you do this. BE GENTLE! You should be pushing the top of the front lens away from the top of the flip. Manipulate the phone in your hands as necessary so that you can hold the top of the front lens away from the phone. Remove your screw driver and close your flip (careful not to let the part you pushed away slip from your grip.)

Step 5: GENTLY pull the front lens away from the flip a little bit and use your hobby knife to cut away at the glue. BE CAREFUL not to knick or cut ANYTHING EXCEPT for the glue when you do this. In this process you will cut a little, and pull a little further away, cut a little, and pull a little further away. Continue this until you have completely removed the front lens. Once completely separated, make sure little to no contact is made with the glue on the back of the lens or the front of the flip. The more you touch it, and/or the more **** that falls onto it (dust or dirt or whatever) the less sticky it will be.

Step 6: Use your T-6 torx driver to unscrew the four torx screws on the front of the flip. These screw hold the inside flip lens down, so once they are out, be careful when you open your flip.

Step 7: Open your flip and gently remove the inside lens. BE CAREFUL. On the i95, the LCD is NOT glued to the inside of the flip. It is held in by the inside flip lens. You'll need to GENTLY remove it from the lens. If you're not careful.. you'll damage your ribbon cable and be screwed.

Step 8: Once your done doing whatever it is you wanted to do that required you to take your lenses off in the first place, just reverse the processes in step 7 and step 6 to attach your inside flip lens again. Then simply pres your front flip lens firmly back in place. If you were careful, the glue should be undamaged and would be PLENTY strong enough to hold your lens securely in place. Presto, you're all set! Enjoy!
