Motorola L7 Common Faults 5

The Motorola L7 is a straight version of the ultra-thin phone launched by Motorola in 2005. Motorola L7 uses sharp red to modify the fuselage, and the side effect looks amazingly thin L7, and returns to the theme of card thinning. With a delicate body and a net weight of 96g, the compact appearance is suitable for both men and women.

The fuselage is equipped with a 176 220 resolution 260,000 color TFT screen, and the small screen makes the display effect rich and colorful.

1。。Install the board, press the pound key and the star key, and then press the power on button, if the black screen appears, you can flash the machine.

2/。。Most of the problems of moto white screen are due to the poor contact caused by the aging of the SIM card, you can pull out the SIM card of the mobile machine, wipe it with an eraser, or go to the business hall to make up a new card.

3。。This problem is a problem with the mobile phone software itself.,I'm also using a mobile custom version.,In order to change the ugly icon,I changed the panel file in the system.,It's OK to boot up for the first time.,But as long as it's turned off.,A white screen appears when it's turned on again.,After flashing the split,Turn it off.,Flash again.。

This kind of problem can only be solved by updating the software, that is, flashing the computer. If you can wipe yourself out, then enter the DOS project mode, and then flash the machine, as follows: in the shutdown state, press and hold the * (asterisk key) (pound key) hang up key, you can enter the DOS project mode.

You can flash it.

If not, it is recommended that you get the after-sales service department to update, the licensed warranty is free, and the parallel goods have to be paid, **50 yuan.

This may be a fault of the automatic power on/off.

This is the reason for the poor contact between the empty battery and the motherboard, use metallographic sandpaper (or eraser) to polish the battery and the motherboard electrocution, if it doesn't work, it is a problem with the hardware or system software of the mobile phone, and you want to go to the repair shop to bring you blind, and you must be guaranteed if you can do orange warranty!

If the battery contacts are not good, wipe them with an eraser, if it doesn't work, try changing the battery.

1.If you can light up the machine, it means that the contact is fine. No need to rub.

2.The phone shows an invalid battery, which means that the phone has detected the battery and the phone"Mismatch".This mismatch lies in the third contact of the battery in addition to the +- pole.

Like Nokia's mobile phone, this contact is connected to an ID resistor, and the resistance value of this contact will be detected when the phone is turned on, if it is compliant, it is considered to be a matching battery, and it can be turned on, and it cannot be turned on if it is not detected or cannot be detected.

If your moto original battery can be turned on normally, it is that there is a problem with the design of these 2 batteries.

If your original battery can't be turned on, it means that the line connecting the phone to this contact is broken, so it can't be detected, go to customer service to repair it.

Haha, don't be afraid of being scared.

It's okay to charge it for too long, that's all.

I'm still like this.

Hey, hey, it's fine.
