Recently I encountered a situation, I flashed TWRP recovery on my redmi 6 pro [Sakura]. After rebooting the device it was getting back to its original recovery due to some rollback features. Fix of this thing was to flash lazy flash zip file but I was unable to flash anything as the internal storage was not mounted in TWRP recovery.
Now at this position, the only solution was to somehow flash the lazy flasher directly from PC but how?
As the PC doesn’t detect your device as MTP when you are in recovery mode(means no file transfer via USB). In this situation, an option is present in TWRP recovery which is called ADB sideload.
What exactly is ADB?
ADB stands for Android development bridge. It is a specific set of drivers through which one can get access to an android phone with USB and can perform various developments. The ADB command is followed by “ADB” e.g. ADB reboot, ADB reboot bootloader.
What is ADB sideload?
Typically an android phone has three modes
You can transfer and access the files of the android phone via PC in ADB mode only, whereas in Recovery mode you can access the files stored in android device’s storage. But ADB sideload is a feature which is available in custom recoveries especially TWRP which enables you to flash the ZIP files stored in your PC into the android device without copying them into phone’s storage.
This may be very useful to people who accidentally deleted their Rom and now are unable to copy/move anything to android’s storage. With the help of ADB sideload one can flash any zip file directly from PC which was supposed to be flashed from the internal storage of android phone.
How to ADB sideload in TWRP recovery.

2. Fastboot setup on PC
3. USB cable & android phone[ofcourse 🙂 ]
