How to Downgrade from Android 7.0 Nougat to Marshmallow 6.0.1

How to Downgrade from Android 7.0 Nougat to Marshmallow 6.0.1



Android 7.0 Nougat has been out for the supported Nexus devices and will be coming soon to other Android devices from Samsung, LG, Motorola, Sony, HTC, Huawei and others. However, you might find some issues or changes in the nougat update that you may not like and would wish to downgrade back to Marshmallow 6.0.1 from Android 7.0 Nougat.
Well, of course you can downgrade to Android 7.0 Nougat from Marshmallow. The process, however, will differ for devices from each manufacturer. All you’ll need to roll back from Nougat to Marshmallow is stock firmware build of Marshmallow for your device, which might be tricky to find for some, but we’ll do our best in this post to help you (at-least for the major Android manufacturers).
As said above, installing stock Marshmallow firmware isn’t same for all devices. Every manufacturer has its own way of installing stock firmware on their devices, like Samsung uses its own proprietary software called Odin, LG has its own Flash Tool, Sony too has a FlashTool, Motorola has RSDLite, HTC has RUUs for each device and Nexus devices come with factory images flashable via Fastboot. And these are just the tools for the major Android manufacturers, but Android is a big world and there many more devices from various manufacturers with different solutions for installing stock firmwares (you may have to use Google for more info)

Flashing a system image
1. Get the right system image for your device, then open up the archive to a safe location.
2. Use a USB to connect your handset/tablet to your computer.
3. Use one of these methods for starting the device in fastboot mode.
• Adb tool: As the device is turned on, execute:
adb reboot bootloader
• Key combo: Shut down the device, then switch it on and instantly hold down the correct key combination for your gadget. To get a Nexus 6P ("angler") into fastboot mode, press and hold the volume down, then press and hold "Power" while the phone is in boot mode.
4. Some users might have to get into the device's bootloader by running:

5. Once the bootloader is up and running, navigate to the location where you unloaded the system image.
6. Execute the flash-all script, which will install the required bootloader, baseband firmware(s), as well as OS.
