How to Fix the bootloop issue on Nexus devices

First of all you need to download the compatible factory firmware for your Nexus device. The downloaded firmware should be the same that your flashed on your device before bootloop and now you need to copy and paste the firmware so that you may have 2 copies of firmware.

Copy the first complete downloaded firmware OTA zip in the extracted adb-and-fastboot folder.

Now extract the second copy of downloaded factory image, now open the extracted folder and locate the recovery.img file from the bunch of other files.

You need to flash the stock recovery.img file using fastboot same as you flash the twrp or any other on your device.

Now connect your device to the PC using USB cable.

Open the adb-and-fastboot folder you extracted earlier and copy the recovery.img inside the adb-and-fastboot folder.

Inside adb-and-fastboot folder, press SHIFT and Right-Click on an empty space inside the same folder.

Click on Open command prompt here as shown in picture below.

“fastboot flash recovery recovery.img”
