In fact, to refresh the official upgrade package, you do not need your machine to have the root
Or S-OFF
, The original version of the machine, as long as the corresponding official upgrade package is found, can be upgraded.

As mentioned above, there are two prerequisites for upgrading the official refresh of the original system:

First, you are upgrading from a lower version to a higher version. After the official package is running, you will first check the comparison version number. If it is from a higher version to a lower version, it will refuse to run. What should I do if I find the new version is not easy to use? The official did not give you this answer, or the answer is: No way, continue to use it.

 

Second, your CID
The verification is successful. If you want to upgrade the Hong Kong version to the Chinese mainland, I'm sorry. The official upgrade package does not allow you to do this (unless you have a gold card ).

 

That's why we need S-OFF.
This step works. That Eng S-OFF
And ship
S-OFF
Which of the following is more suitable for official packages?

Of course it is the latter, because it has been mentioned many times in the previous article, and it is no longer so arrogant here.

 

I do not recommend that you upgrade the official refresh, although the ship
S-OFF
You can upgrade or downgrade at will, but the upgraded system does not have the root
And currently cannot be obtained. What is the purpose?

 

Of course, radish and cabbage have their own love, and I don't like them as much as you don't like. So here I will provide some methods to anyone who needs them. the upgrade process is simple and fully automated. I am too lazy to capture pictures.

 

 

Running Conditions:

1,

A dhd with sufficient power
Mobile phone.

2,

An official ruu
Start with exe
File, we suggest you go here to find:

3,

Install HTC Sync on your computer
Synchronization software.

4,

Connect your phone to your computer using a data cable and select sync
"Synchronization mode.

5,

Run ruu directly on your computer
File.

6,

Start to brush the machine. Follow the prompts on the Interface halfway. Do not remove the data line. Wait patiently for the upgrade to complete.

 

 

The principle of the official upgrade package. After running the program, the system will first compare the version number to see if the upgrade from low to high is met. Then, the system will verify the CID
Check whether your verification code is consistent with the package to be refreshed and whether it is in the same region. If they all pass, they will start to flash the machine. He will first shut down the security lock and then start to upgrade, Rom
Each partition in it will be overwritten, including hboot
, Radio
, Boot
, System
, Userdata
, Cache
Boot screen, etc., is a complete Upgrade Method (we usually brush the third-party modification package, only brush boot
And System
Partition ). After refreshing, open the security lock.

 

Ship S-ON
MACHINE:

As long as the conditions meet, you can brush, brush or ship S-ON
.

 

Ship S-OFF
MACHINE:

Because the security lock has been closed, so you can skip the detection to brush, brush or ship S-OFF
.

 

Eng S-OFF
MACHINE:

Because the security lock has been disabled, you can skip the detection and flash the machine.
The partition is overwritten, so our modified version of ENG hboot
No, changed to the official original, so S-ON
Again turned on, so your machine turned back to ship S-ON
.

 

No matter which machine is upgraded through official refresh, the original root will be lost.
Permission, if you already have permissions.
