Fastboot Android-product-out Not | Set

Instead of:

fastboot: ANDROID_PRODUCT_OUT not set You typed what you thought was the correct command, but instead of flashing, Fastboot just stares back at you with that vague error. Don’t worry—this is a common hurdle, and fixing it is simple once you understand what’s happening. In simple terms, Fastboot is looking for an environment variable called ANDROID_PRODUCT_OUT that points to a folder on your computer . This folder should contain the compiled Android images you want to flash (e.g., boot.img , system.img , vendor.img ).

echo 'export ANDROID_PRODUCT_OUT=~/android/out/target/product/raven' >> ~/.bashrc source ~/.bashrc Just remember to update the path when you switch devices or build new images. The ANDROID_PRODUCT_OUT not set error is simply Fastboot’s way of saying, “I don’t know where your images are.” It’s not a bug or a driver issue—just a missing pointer. Whether you set the variable, use absolute paths, or source your build environment, you’ll be flashing again in seconds. fastboot android-product-out not set

source build/envsetup.sh lunch <your_device_choice> After that, the variable is automatically set. You can verify with:

export ANDROID_PRODUCT_OUT=~/android/out/target/product/raven Instead of: fastboot: ANDROID_PRODUCT_OUT not set You typed

fastboot getvar product If that works without errors, you’re good to go. If you constantly work with Fastboot and AOSP, add the export line to your shell configuration file ( ~/.bashrc , ~/.zshrc , or ~/.profile on Linux/macOS). For example:

$env:ANDROID_PRODUCT_OUT="C:\path\to\your\images\folder" Once set, run your fastboot command again. You don’t actually need the environment variable. Simply specify the full path to the image you want to flash. This folder should contain the compiled Android images

echo $ANDROID_PRODUCT_OUT After setting the variable, test it:
