Hello everyone, I am a Gautam recalled.

Everyone with red rice 1S Unicom / Telecom version of the installation and the effects of the dual system of video presentations.

This program is one of my early ideas, but recently have time to complete.

Here the dual system, the device is used on both jacket Andrews version of the system is not running the two systems simultaneously.

So there will be no use of the dual system, the phone will be card problem, run only one system, the other is not running.

The role of the dual system is that you can use every day one system and the other is used to test and experience some of the newly released rom.

This rom playing machine enthusiasts and developers, is very helpful.

Another will not be any impact between the two systems, because they are independent, of course, in the latter, I'd make the data of the two systems coexist.

That data coexist: On a system installed the software can be run on another system.But for now, I have not been able to achieve.

This program does not require the user to modify any system files and content.

As long as I have provided in accordance with the method, you can install any of the two systems, and can be changed at any time.

Like computer dual systems, but is simpler than a computer. Because I have put all operations are inflicted fool is operated.

Two systems such as video can easily switch directly by software.

Dual system, you do not have to worry about new rom released official or private, to test the experience and clear data to reinstall the system.

If not used, you have to brush back to the original system, but also to restore the data, which would be particularly troublesome.

Dual system, as long as the rom installed on another system, not with the direct switch back on the line.

Dual system encountered a problem, remember microblogging feedback oh!

Note: Not syhost reference method, this is my plan early

First, before the installation instructions:

1. Installation is simple, but I will explain in detail, it may be a bit more than words, watching might feel a bit complicated, but the whole operation is a fool.

2. The installation process does not require a computer, you only need to use the phone and tools I offer package and follow the step by step tutorial to operate my offer.

3. The installation process if the phone can not boot up, do not get excited, definitely not your operation, again according to the tutorial to do it again.

4. ******* install a dual system will format the built-in memory card, back up your data before using *******

5. Once installed ******* can not use a wire brush official dual system tools, only brush card, there is not much impact, but I will try to think of ways ******

6. or reminder, any brush machine operation has risks, be careful line, the problem caused by the brush with the author unrelated.

Second, the phone has conditions:

1. The phone must if red rice 1S Telecom or China Unicom version version

2. The phone will need to install a third-party recovery, when I tested with TWRP

Instructions:

1. This tool must have shortcomings, such as the problems encountered in the process, please use the feedback to my microblogging

2. The so-called lack of intelligence is not a lot of features, such as the current system is not yet functional tool (the latter will join) identification operation which needs to know the current system, or data will confuse

Step 3. Install the tutorial just figured I probably, not to be rigid rigidly follow suit, this tool is very flexible, you can use a few of their own free operation

3. Switch software and HM1S-System-Menu.zip the system can achieve switching system switching function

4. Install the switch software, be sure to pay attention to is that the current system is necessary to install the system in which the toolbox, or switched data and system will go wrong

5. When switching system, which must pay attention to the current system, we must choose to switch to another system, if they choose to switch to the current system data will be wrong

6. Install or uninstall a dual system, all things are restored, there is no way the case can be used

7. This tool will continue to improve in the future, remember to check the process of using the support of Oh!

Installation ideas:

A lot of oil, said the installation is unsuccessful, I am here to talk about the idea, we first need to install the dual system

Then we have two air systems, so now can not boot, we need systems

First, install the first system, install the system and the card the same brush step, the installation will be able to boot up

The next step is to install the second system, the system is now in one, certainly can not install a second system

So we can install a key switch system software, or directly with a tool bag system switching function to switch to the second system

After the two switching systems, because there is no loading system is empty, so you can not open the opportunity card MI

So we re-enter into recovery, brush a rom, so the system is installed the two

Then a key switch software installation system, two, or direct switching system inside the toolkit, you can enter the system one of the

Then you can easily switch the two systems

After the installation of the system you want to delete one system to another system retains how to do?

Since the data of the two systems in a data area, with clear data recovery will erase the data of the two systems

Therefore, the current function of the system data toolkit provides clear, as long as you want to switch the system to switch to

Use the toolkit to clear the current function of the system

Then you want to brush brush rom, switching software installed on it
