In line with self-reliance, there is a lot to find at Majia.

There is no scientific and technological content in rushing to the foot, so I found a reasonable price. By the way, under a single battery, the last time the battery seller sent a piece of the problem is still the same, in exchange for the original is also in a hurry, they also found a good home to touch the luck, in fact, if you want insurance or direct buy Scud The battery is just fine.

Two express delivery at the same time, this is not bad, at least do not have to split twice! The left is the battery, a set of disassemble tools, the right is the button cable, but also sent a screwdriver! This is really good.

The battery is in an electrostatic bag and looks pretty regular! However, after taking a closer look, I discovered it.

60x magnification, the details of the font printing are blurred, and the joint solder joints look normal! ... It seems that this time it will be pitted again.

This is the culprit, the line switch, but think about it took 2 years to issue, compared to the red rice NOTE has been enough for a long time.

The newly purchased switch cable, in fact, good workmanship can directly buy micro-switch welding, but ready-made is not expensive, you do not have trouble.
