Lets tacklethis rough question together.
The OS on Android can be changed — it’s called installing a custom ROM (Read-Only Memory).
Let me give your curious mind a short, clear overview of how to change an Android OS and install a custom ROM.
⚠️ Warning
Be careful — this process can erase all your data or break your phone if done incorrectly.
Steps to Change Android OS (Install a Custom ROM)
1. Backup Your Data
I mean everything first: contacts, photos, and files — because replacement of your OS is capable of wiping out your cherished data, rendering you information-less.
2. Unlock the Bootloader
Go to your phone’s Settings → About phone → tap OS version 7 times to enable Developer options.
After that, go back to your settings, scroll down and find Developer options, then enable OEM unlocking and USB debugging.
3. Use Your PC and Command
Install a custom recovery (like TWRP).
Ensure you download the correct TWRP image for your phone.
Run the command:
fastboot oem unlock
(This wipes your device.)
In case you don't know what Fastboot is — it is a diagnostic or repair tool that can flash firmware or restore an operating system.
4. Boot into Fastboot Mode and Flash It
fastboot flash recovery twrp.img
5. Download a Custom ROM
Examples: LineageOS, Pixel Experience, Evolution X, etc.
Also download GApps if you want Google services.
6. Flash the ROM
Boot into TWRP recovery, which is your recovery app you must first have downloaded and activated.
Wipe data, cache, and system.
Tap Install, choose the ROM zip, and swipe to flash.
(Optionally, you can flash GApps.)
7. Reboot the Device
Once done, reboot your phone — it’ll start with the new OS.
Is the Tool and Method for Flashing Your Phone Dependent on the Model and Phone Brand?
Yes, it is phone brand and model dependent. Each Android device has:
- Different bootloader unlock methods
- A unique recovery image (TWRP)
- Specific custom ROM builds
So, you must always use files and instructions made for your exact phone model (e.g., Samsung Galaxy A52 or Xiaomi Redmi Note 12).
Using the wrong ones can break your phone.
Can You Change Android OS to iPhone OS?
Because you change the OS of your Android doesn’t mean you can transit from your Android to iPhone. It must be another OS your device supports — and that will be within its ecosystem.
Android and iOS are completely different operating systems — iOS is closed-source and made only for Apple hardware, while Android is both a closed and open-source operating system.
For example, AOSP (Android Open Source Project) is open source, but Google’s proprietary store (like the Play Store) is closed source.
Did you catch the difference?
Besides, you can make Android look like iOS using launchers, icon packs, and themes.
But you cannot install real iOS on an Android phone.
Therefore, you can mimic iOS, but not replace Android with iOS.
So Why Can't You Change Android to iOS Since What We Are Changing Is the OS and the OS Was Claimed to Be Changeable?
Good question — and here’s the short reason:
Even though Android’s OS can be changed, iOS isn’t compatible with Android hardware.
1. Closed Source
Apple doesn’t release iOS code publicly, so no one can install or modify it for other devices — it is a closed-source system.
2. Different Hardware Architecture
iPhones use Apple’s own chips and firmware, which work only with iOS.
3. Secure Boot and Encryption
iOS only runs on devices that pass Apple’s hardware verification.
4. Drivers and Firmware
Android devices use different cameras, screens, radios, etc., and iOS has no drivers for them.
