Title: How to Use fastboot set active slot for Android Game/Device Issues in India
Introduction
fastboot set active slot is a command used in Android devices to switch the active OS slot (A or B) when the device is in Fastboot mode. This is often required for fixing system issues, updating partitions, or troubleshooting games that malfunction due to slot conflicts. Below is a step-by-step guide for Indian users.
Steps to Use fastboot set active slot
Enter Fastboot Mode
Turn off the device.
Press Power + Volume Down (or Power + Volume Up) repeatedly until you see "Recovery" or "Fastboot" mode.
Use fastboot oem reboot bootloader (if needed) to ensure Fastboot mode.
Check Current Active Slot
Run:
fastboot getvar current slot
The output will be slot-a or slot-b.
Set Active Slot
To switch to Slot A:
fastboot set active slot a
To switch to Slot B:
fastboot set active slot b
Reboot the Device
fastboot reboot
Common Issues & Fixes
Command Not Working
Ensure the device is unlocked (Bootloader unlocked).
Install Android SDK Platform Tools (from developer.android.com) on your PC.
Use USB debugging (Enable in Developer Options).
Device Stuck in Fastboot
Connect to PC via USB and run:
fastboot oem reboot
After Switching Slot, System Crashes
Flash the correct boot image for the new slot using fastboot flash boot <path>.
Reinstall system partitions (e.g., fastboot flash recovery recovery.img).
Why This Matters for Indian Devices
Network Unlocking: Some Indian carriers lock devices to specific slots. Switching slots may bypass restrictions.
Game Crashes: Games like PUBG Mobile or Call of Duty might fail if the active slot is corrupted.
Faster Updates: Use the non-corrupted slot for smoother OTA updates.
Important Notes
Data Loss: Switching slots does not delete data, but flashing partitions can.
Brand-Specific Commands: Some brands (e.g., Xiaomi, Realme) use fastboot oem set_active slot a/b. Check your device’s manual.
Safety First: Backup important data before attempting slot changes.
