Is there any tool to enable dual boot on android?
I have a OnePlus 8 and I would be interested in having a main Rom with LineageOS for MicroG for regular use, and an emergency Rom with the official OxigenOS Rom + Google services

I think he doesn't mean that dual booting. I think he means dualbooting between different ROMs. Like for my S3 I got Dual booting with Siyah Kernel between CM10.1 and 4.1.2 Touchwiz. For S3 you have much kernels supporting dual boot. So you just need to find the right kernel for your device. I think there are much devices having these kernels!
To tell the truth, I was not sure if it is what @siddheshvartak was looking for.
So dual-boot/multiboot only Android:
- some Xperias have a multiboot: LINK to thread
- Lenovo A390 and few other Lenovo smartphones
- Nexus 4, 5, 7 (https://play.google.com/store/apps/details?id=com.tassadar.multirommgr)
That's all I know about it.
I'm sure there is much more multiboot/dualboot equipped smartphones.
yehhh
I was talking about dual boot between the ROMs.....

[ROM] Flyme OS Latest 4.5.4.2 for Mi4i

Hi all my dear Miui users,
Finally the wait is over and you can download all new Flyme os for mi4i not just flyme can be called Fly me. As i see most of them waiting for an eye-striking Rom without any bugs I Present you the Flyme. This is the UI for Meizu phones, and also an customizable rom with hidden features leaving us in a mystery.
What is flyme OS ?
Flyme OS is a stock and after market firmware developed by Meizu for smartphones based on the Android operating system. Some its key features are completely redesigned apps, one-handed usability and performance optimizations. The initial version, Flyme OS 1.0 based on Android 4.0.3 was released on Juny 12, 2012. It was praised by critics for its simple yet beautiful interface design. Flyme OS 2.0 was released later in 2012 . It brought improved cloud services and build-in root support, among other improvements. Flyme OS 3.0 was released together . It was one of the first Android firmwares to integrate a flat UI. Since Flyme OS 3.0, Dirac HD Sound is integrated, bringing an improved audio experience through a certain number of ear and headphones. The successor the Flyme OS 3.0, Flyme OS 4.0 was released in 2014.The current version of Flyme OS, Flyme OS 4.5, is based on Android Lollipop.
So to start enjoying Meizu in your phone [ I mean Flyme os in Mi4i ] .
Requirements for flashing Flyme:
A working Mi4i phone with enabled USB debugging
To enable USB Debugging Tap on MIUI Version 7 times and go to additional settings then to developer options - scroll down and look for it
Your Mi4i should have either 5.6.11 or 6.6.10 MIUI version so as not to have any bootloop
Rooted phone with a custom recovery like TWRP installed [ twrp is recommended]
Download Gapps and Flyme for Mi4i in root of your device storage with links at last
Phone Battery Charged Above 70% At Least.
Backup the original system data (contacts, SMS, application data, etc.)
INSTALL INSTRUCTIONS
Boot into recovery
Clear Data.
Clear Cache.
Clear Dalvik Cache.
Flash flyme_MI4I file from from internal SDCard.
Clear Cache and Clear Dalvik Cache.
Reboot.
Note in the initial boot it takes 5-10 minutes and phone gets hot like red hot iron. and after booting then retart and install Gapps
Disclaimer : I didn't created this ROM, i am just sharing this ROM itself without making any modifications and source link is provided below. If anybody wants more info then he/she can visit the source link. Thank You !

Getting into rom development?

Hello everyone, I'd like to ask the following question(s).
Background: I've got experience in programming Java, C#, Python and I've messed around other programming languages before.
I'd like to get into the entire ROM building / compiling / 'cooking' scene but I am clueless as where I could start. I've a Zuk Z2(plus) with an unlocked bootloader and TWRP 3.1.0-3 installed.
Rom: AOSPExtended V4.4
Kernel: DarkMoon Experimental 178
Mod(s): shox_Audio_Mod V1.4
Gapps: Opengapps micro
Root: Magisk V13.2
I've been testing lots of roms recently, and now I am getting interested in (as mentioned above) compiling my own roms and maybe even port a rom myself? I'd start out with testing on my Zuk Z2(plus) since I can recover this device from any kind of software-brick. The main reason I'd like to mess around in this scene is because I've got an older tablet laying around with a MTK SOC, but with android 4.4.4 and I'd like to be able to update this
Tablet I'd like to upgrade (eventually): Cube T9 (currently only supports android 4.4.4)
I'd like to create a ROM based on one of these tablets: https://www.aliexpress.com/item/BOBARRY-10-inch-screen-for-T109-only-a-screen/32801822243.html
It might be completely fake hardware specs, I only hope that the SOC and the android version are correct (Maybe someone can confirm this for me)?
It's the only other tablet I've found running the MT8752 SOC and an android version higher then 4.x.x.
Any idea's tips or places where I could start best? I am open to all suggestions so please comment below

[Q] A few (partially technical) questions about Android Go

Welcome,
I have some (partially technical) questions regarding the lighter version of Android - Android Go (Oreo Edition).
1. Does Android Go provide full support for applications dedicated to "normal" Android? Has it been somehow trimmed in terms of compatibility?
Of course, I omit porting an application to newer Android version in general. Rather a comparison with "full" Android Oreo or other versions.
2. Does Android Go also support Project Treble enabled drivers?
3. Does the obligation of supplying Project Treble enabled vendor implementation and minimum 4.4 kernel version for devices shipping with Android 8 refer also to Android Go?

[ASK] Sailfish OS for Android One Devices

I've saw Sailfish OS ported to many devices, even older one like Xperia series.
I'm curious if any Developers here have project for Android One, especially the 1st generation.
My questions:
1. Is there any Sailfish OS rom for Android One? in now or near future (is there any related links)
2. Can i flash the Sailfish OS from other images, like for Redmi 1, would it work?
3. If I only want to try this OS, which device you guys recommend me to buy, just for flash the image and get experience?
4. from 1 to 11. How hard it is to port Sailfish OS till get it to work?
(im just common people with no developing and scripting skillz)
Thank you so much if you guys reading this.
(yes. i have broken english)
