[Moto G Stylus (Moto G Pro) Questions & Answers] Meraz@josenart:
Experiencing a black screen after flashing a Generic System Image (GSI) on your device can be frustrating. Here are some steps you can take to troubleshoot and hopefully resolve the issue:

1. Try Force Restarting Your Device​

Sometimes, a force restart can help recover your device from a black screen:

For most Android devices:

Press and hold the Power button and the Volume Down button simultaneously for about 10-15 seconds. This usually forces the device to restart.

If this doesn't work, try pressing and holding the Power button for about 30 seconds.

2. Boot into Recovery Mode​

If a force restart doesn't work, try booting into recovery mode:

For most Android devices:

Power off the device (if it's still responsive to the power button).

Press and hold the Power button and the Volume Up button simultaneously. Some devices might require you to hold the Volume Down button instead.

Release the buttons when the device logo appears or when you enter the recovery menu.

Once in recovery mode, you can try the following:

Wipe Cache Partition: Sometimes, clearing the cache can resolve boot issues.

Factory Reset: This should be a last resort as it will erase all data on your device.

3. Boot into Fastboot Mode​

If recovery mode doesn't work, you can try booting into fastboot mode:

For most Android devices:

Power off the device.

Press and hold the Power button and the Volume Down button simultaneously until the fastboot screen appears.

Once in fastboot mode, you can try:

Reflashing the Stock ROM: If the GSI image is not compatible or if there was an issue during flashing, you might need to reflash the stock ROM.

4. Use ADB Commands​

If your device is recognized by your computer, you can use ADB (Android Debug Bridge) to attempt to fix the issue:

Connect your device to your computer using a USB cable.

Open a command prompt or terminal on your computer and navigate to the ADB directory.

Type adb devices to check if your device is recognized.

If recognized, you can try rebooting the device by typing adb reboot.

5. Check for Hardware Issues​

If none of the above steps work, there might be a hardware issue, or the GSI image might have caused a severe software problem. In this case:

Visit a Professional Repair Service: If your device is under warranty, contact the manufacturer or the place of purchase for support.

Use Manufacturer-Specific Tools: Some manufacturers provide their own software tools for recovering and reflashing devices (e.g., Samsung's Odin, Xiaomi's Mi Flash Tool).

6. Flash Another GSI or Stock ROM​

If you're able to access fastboot mode, try flashing a different GSI image or the stock ROM. Here are the basic steps:

Download the appropriate GSI or stock ROM for your device.

Connect your device to your computer in fastboot mode.

Open a command prompt or terminal on your computer.

Use the following commands to flash the images:

bash

Copy code

fastboot flash system system.img

fastboot flash boot boot.img

fastboot flash vendor vendor.img

After flashing, reboot your device:

bash

Copy code

fastboot reboot

Important Notes:​

Ensure that you have unlocked the bootloader before flashing images.

Double-check the compatibility of the GSI image with your device.

By following these steps, you should be able to troubleshoot and resolve the black screen issue after flashing a GSI image. If the problem persists, seeking professional help might be necessary.
