The owners of today's popular and prestigious IPhone mobile phones often need to open the back cover. This is not as easy as with other phones. Here you will have to follow certain instructions and have some skills in working with small details. So, if you are the owner of an IPhone 3g, or an IPhone 3g 4.2, or have purchased a Chinese IPhone 3g, follow these steps to remove the back cover.
Instructions
Next, attach the suction cup to the screen and gently pull it towards you. Do not make any sudden movements, as the loops may break, and the IPhone will stop working altogether.
You should see numbers in orange circles below the screen. Exactly in the indicated order, according to these numbers, disassemble the phone. Take a pair of tweezers and carefully lift up the flex cables that hold the screen and touchscreen. They are marked with numbers two and three.
Immediately afterwards, use a Phillips screwdriver to remove all eight screws holding the metal plate. Put them all in one place so you don't lose them. Try to put all the small parts from the phone in a place where no one could reach them. This is very important, since it is extremely difficult to find replacements for such parts. Then remove the two loops numbered 4 and 5. After that, carefully lift the loop under the 6.
Carefully remove the metal plate, being careful not to touch the microcircuits. Then carefully separate the battery from the back cover. For reassembly, it is recommended that you purchase a thin double-sided tape in advance to re-attach the battery to the cover.
Then remove the vibration with fine tweezers. Remove all parts and screws remaining inside. In the last step, remove the display by unscrewing the remaining six screws. You have now reached the lid and can do whatever you need to do with it. In most cases, this procedure is carried out when they want to change the cover or repair it.
