How to put the phone in his hand two or more firmware. DualBoot.
What is DualBoot?
When two or more versions of the operating system installed on your phone (for example: Android 7.1 and Android 4.4), with the possibility of choosing one of them.
Pros DualBoot: Opportunity to put two or more versions of the operating systems with different functionality, such as: firmware based TouchWiZ and AOSP.
Cons DualBoot: Free your phone memory or SD card will decrease by 3-6 GB
- Make a backup of all data via rekaveri and copy them to a PC or external memory card !!!
- Download the necessary files to your phone:
- Hence swing app for Android - version of the program can be anything.
- And the PC application - version of the program can be anything.
- Second firmware file that you want to put the second rum (Attention!to see thatcoresecond flashsupported Dualboot) Or was it build.propyour phone model!(Find string ro.build.product = YOUR MODELRead more in the latest spoiler )
2. Preparation of the second firmware.
- Charge your phone for at least 60%.
Put on your first (main) .apk file firmware you downloaded from the site. Put, run, Ruth and allow the pop-up window, click "Now"
Now there are two ways:A.
Patch .zip firmware via phone (which will take longer)B.
Patch via the PC. I will tell you two ways.A. smartphone.
Go to the application is put before - "DualBootPatcher". Run. Go to the "Patch Zip firmware" then click on the "red plus" in the lower right corner, choose the second firmware, configure your phone version and in which slot will be set, for example, / data (if you put in the / data then choose Data-slot if what the other - look and look desired slot), a field where there is a "1" - the number of the second firmware (choose any figure, the main thing to remember - this is a slot into which you put a firmware implemented to be able to put one firmware. in / data-1, the second in / data-2, third ... and so on). And click "Continue". Everything went firmware patch.B. PC.
Similarly as in the phone. Extract from the archive: "DualBootPatcher win32.zip".exe file and all other files
and put the program on your PC. In the window, select the following parameters:
Where: "Device" - the model of your phone, "Install to" - in which slot will be put. (You can choose a different slot, all similar in the app on your phone). Then click "Choose file" and choose the very second firmware, which will be put. Everything went firmware patch.3. Installation:
Now that you've patched firmware file with the second, it must add "weight" (3 - 8 megabytes), and Title Add a slot where you patch it (for example, if I put the firmware inData-slot
and put the number "1
"At the end of file names will be:... data-slot.1
.zip or something like that). Now it is small, and making sure that theYou make a backup
And that the firmware should a kernel that supports DualBoot (or build.prop spelled ityour phone model
), You can start. Go to rekaveri (Do not put the patched file from underOdin'a, otherwise you will kill your phone!
) And setPatching
.zip with the second firmware. All. Now when you reboot from rekaveri in, you will find yourself in the second firmware (butanimatsiya will go from the second firmware). We set up a second firmware, porting applications, contacts, etc. (if you want to).P.S.
If you've got butlup, then the core of the second firmware does not support DualBoot (or build.prop spelled not the phone model). Look core that will support it, patched it through an application on your PC and place as well as becoming the second firmware, or tweak a file build.prop line ro.build.product = ON your phone model, or reboot into rekaveri downloadfrom here
, Put this file:
and switch to the first (primary) Rom.4. Conclusion:
Now to reboot first (main) firmware, it is necessary to put the second Rom, already familiar to us the application: "DualBoot patcher", allow Root and click the pop-up window: "Now." All you can now switch between the firmware.
All of your files (video, photos, music) are available in the File Manager from both a first and a second of the firmware. (exactlyfiles
And not the application!)5. Note:
Do not forget, if something needs to be establish through rekaveri inthe second
firmwarepatch file in the same way as the firmware
. Thus, filling any ukrashalki, gapps, purification from excess software scripts,pre Patches them through the program on the PC or on the phone. If the target rum / data - Patch to use the archive to / data.Otherwise kill the main rum!P.P.S.

Supplement (MUST READ)
Previously, when I delved into dualbute I rested only dualbuta support in the kernel. And I looked for the kernel that supports it. But now I have found an indirect solution to the problem if the core is not and you have a second firmware is based on cyanogenmod (lineageOS). Because any file with the firmware, you can unpack, edit and re-assemble and sign, the work will not make edit build.prop.
Find the line ro.build.product = (and immediately after the symbol=cost phone model) If there is worth precisely your model, you can go quietly and put a patch over rekaveri.
If the model is different (for example you have a firmware ported) is changing the word after the sign=on your model.
