i900 refurbished problem, i9000 how to tell if it is a refurbished machine? ?

Although the Samsung i900 has been on the market for more than a year, it depends on whether you can recognize it!

It will not recognize whether the phone you bought is refurbished or not! That can only blame yourself for being unlucky, blaming yourself for not having a new understanding of this aspect!

I will teach you a few simple ways to identify whether it is a second-hand mobile phone and an original mobile phone!

When you buy a mobile phone, first look at whether the USP interface has entered the meeting, or the traces of water and so on!

Look around the screen for any signs of slipping.

Look at the communication records in the mobile phone to see if it has been called, and whether there are any redundant **, files and other leftover and deleted records in the mobile phone's own memory!

The high imitation is still very good, but the difference is just the appearance of the image, and there is still a huge gap between the internal structure and configuration and the parallel goods. It takes some experience to distinguish between refurbished and second-hand ones, but it is not impossible to distinguish First of all, observe whether the screws have been screwed If the machine has any warranty or store labels, it is best to tear them off and take a look, because if there are scratches on the mobile phone, JS will generally put their store or warranty label on that place to cover up. Look at the screen for dust and scratches on the sockets.

There is another way to distinguish whether the machine is refurbished, that is, to smell it, the new mobile phone has a special smell (sandalwood fragrance), and the smell will disappear after using it for a period of time (it should not exceed half a month). Take a closer look at every detail.

In fact, when I first bought i900, I was afraid of buying a refurbished machine or a customized machine with a network lock, and I also bought a new version of the Singapore version of the i900 8g with 2440 yuan on **, the stylus is triangular, and the following is for your reference.

How to check the factory date:

, return, return, press 2, then press 1, then press 5, and the last line shows the factory date.

Identification method of customized machine:

1. Start - Settings - System - Version - Mobile Phone: nspro, this is a customized machine that has been unlocked, and it will be locked on the network after re-flashing.

2. Enter "*" on the dial panel to see the second item "network lock", if it is "enabled"."If it is selected, it means that the machine has a network lock. This is a customized machine, and there will be a network lock after re-flashing.

If you are still afraid of a refurbished machine, reset the mobile phone format once "code chip reset", and then test it in the same way as above, and enter * to see if the serial code is the same as the code on the machine, and the parallel cargo machine will generally be followed by 01 two numbers when entering, which is normal, the number in the first place represents the place of production, such as 02 is Hong Kong.

What my friend said above is basically a way to see if it is renovated. As for your second question,It should be a screen highlight,If there's only one,It's normal,It's okay if it doesn't affect the others,If there are too many highlights,It means that there is a problem with the quality of the screen,How to deal with it, just look at it。 Have a nice day!

This is more difficult, according to **, 3000 below are refurbished machines, but more than 3000 may not be brand new.

Flashing Failure Resolution:

1.If the situation is better, you can go to recovery: re-brush, or change to another brush.

2.The situation is severe and it is impossible to enter Recovery. You need the official RSD cable flash package and kernel, go to fastboot, use the cable brush to re-flash the official system, and then re-flash the third-party recovery (the same steps as the first flash).

3.The situation deteriorated, the phone did not respond and could not be turned on. This is the standard brick machine. Don't worry, it may be that the battery is dead, make.

Fully charge the battery with a universal charge. Or replace the battery. As long as you plug in the computer and there is a response, you will be saved. After the battery is fully charged, enter fastboot, use the cable brush to reflash the official system, and then reflash the third party.

recovery (same steps as the first flash).

If you use recovery to brush, it is too complicated for you to put the zip format package into the mobile phone SD card, and now you can't turn on the phone, you can only put it into the external SD card, so it is recommended to dig coal brushes.

The format of the coal digging brush machine mode is generally tar with PDA brush! Now it's simple. First make sure that you don't have the driver installed on your computer, and the odin will recognize your phone and there is a display!

Select a package in tar format with PDA. Then the dot starts. If your machine can dig coal, it means that there are no bricks.

Find a package to unzip out of tar format. Continue with doubts.
