I often brush P800, and the blank screen is usually because the TF card and SIM card in your P800 mobile phone are not taken out. You can take them out and brush your phone with RUU, and RUU will automatically turn off your phone and restart it to enter the three-color screen. [There is another way to manually enter the three-color screen, which I haven't tried, because I use RUU to brush the machine without manual setting. ]

Note: Make sure that SPL has dropped to 1. 1 1.0000 before brushing, otherwise it is likely to be brushed into bricks! ! !

Unlock, tri-color screen, IPL, SPL, CID and SuperCID zt.

Unlock:

This is the simplest. In order to strengthen security, wm5 has many strict restrictions, and many programs without digital signature or involving the system will be rejected. Unlocking is to open the lock, and there are many ways to realize it. The principle is to modify several key values of the registry.

Three-color screen:

Be sure to enter it when you brush the machine, which includes some information, such as IPL and SPL. If you use the RUU brush tool, the brush will enter itself. Generally speaking, you can enter by pressing the camera button and then pressing the power button.

I understand that this is equivalent to the computer's self-test screen, that is, the computer does not enter the windows screen.

HTC p 3300/ dopod P800] How does dopod p800(htc3300.w) enter the three-color screen (a brush machine must know)?

Hold down the power button+record button, poke your ass, ok, connect the data cable, and comrades who fail to set the screen can use RUU to brush the machine! ! Support it! !

IPL and SPL:

IPL and SPL are essentially two parts of windows mobile's Bootloader, and the program started by wm is IPL-spl-OS.

The full name of IPL is Initial Program Loader, which is responsible for the power-on management of the motherboard and loading SPL into ram. If the IPL is damaged, it can be said that the mobile phone is basically invalid, and it can also be solved by the manufacturer's hardware maintenance.

The full name of SPL is Second Program Loader, which is responsible for loading the OS operating system into ram. In addition, SPL also includes many original system commands, such as those used in mtty. If SPL is damaged, it can be rewritten with a burner.

IPL and SPL versions can be viewed in a three-color screen, and a hard boot will also be displayed.

It is equivalent to the BIOS of the computer, and the three-color screen above is also in this one.

CID and SuperCID:

These two are actually the same thing. Simply put, this is what various manufacturers or operators use to limit brushing. Because of the openness of windows mobile, dopod can produce and oranges can also be produced.

CID is a logo used to mark the manufacturer or operator. If you directly paint dopod's ROM orange, it will fail.

SuperCID is a super special CID symbol. After rewriting the mobile phone to SuperCID, we are not afraid to brush any ROM.

The methods to view SuperCID are: first enter mtty normally, and then enter info 2. If "HTCSSuperCID HTCE" appears in the last line of the message, it means that it is a super CID.
