How to Replace the Lithium Battery
Replacement Procedure
1. Remove the Main PCB.
2. Remove the Lithium battery and then replace it into new one.
How to Discharge the Capacitor on Main PCB
1. Put the insulation tube onto the lead part of Resistor (1kOhm /5W).
2. Put the resistor between both terminals of capacitor on MAIN PCB for approx. 5 seconds.
3. After discharging confirm that the capacitor voltage is lower than 10V using a voltmeter.

Service Mode - Error Code Memory Function
1. General description
This unit is equipped with history of error code memory function, and can be memorized 16 error codes in sequence from the latest. When the error is occurred more than 16, the oldest error is overwritten in sequence.
The error code is not memorized when the power supply is shut down forcibly (when the unit is powered on by the battery, the battery is pulled out) because the error code is memorized to FLASH ROM when the unit is powered off.
2. How to display
The error code can be displayed by the following procedure:
Before perform the error code memory function, connect the AC adaptor or insert the battery.
(Since this unit has built-in memory, this error code memory function can be performed without inserting SD memory card.)

Huawei P7 – Disassembling procedure – How to replace the screen

Heat the glass panel on the back to around 85 Degree C so the adhesive loosens.
Use a plastic spudger or opening tool to gently pry up the glass.
Carefully work your way around the edges.
Be careful at the bottom. There is a flex cable running near the back-glass.
Never use metal tools for this. Metal will scratch the black paint off the back plate.
First, disconnect the battery cable.
Use a philips screwdriver to remove the shield, revealing the battery connection.
Next, disconnect the LCD/Digitizer ribbon.
Remove the battery.
Use plastic tools to pry the battery off its adhesive.
Don't bend, or heat the battery.
Heat the front side to about 85 Degree C.
Using a plastic tool, separate the display from the frame, but don't pull it too far away.
Flipping the phone over, can see the display ribbon.
Make sure none of this cable is stuck to the frame.
Pull the display ribbon through the frame.
If the screen broken while removing,make sure there is not a single glass-shard left on the frame. Any little splinter will cause significant damage to the new screen you're about to place.
Tape up the whole frame with double-sided tape for a perfect fit that won't become loose.
Put the new screen in.
