There are 2 ways to get a Lollipop update: The first method is a lot easier and highly recommended for novice users, but it might take a while before a device gets OTA update. However, it also carries more risk and requires more technical expertise. So all apps, books, music, movies, all files you store in the device will be totally deleted.
So make sure to do proper backup before starting. This is the result of my experiment. It should work, but I am not responsible to anything that might happen from doing these steps.

Join Date: Nov My Devices: Apr Jan Dec When I download the images it doesn't contains Angler-bootloader and Radio. It only contains one file with the boot. I tried downloading all the 6. I don't understand. Junior Member. Otherwise, you'll need to run a single Fastboot command—but note that this will wipe all data on your device.
Before we get into this part, note that I'll be listing the commands for Windows users. Mac users will have to add a period and a slash. If that returns a series of letters and numbers followed by the word "fastboot," then your device is connected properly and you're good to go.
Install Android SDK
Otherwise, refer back to Step 1 to check your ADB and Fastboot installation, and ensure that your device is in bootloader mode as shown in Step 3. Next up, it's time to unlock your bootloader. Depending on the Android version your device shipped with, this will be done in one of two ways. At this point, you'll see a message on your Android device asking if you're sure you'd like to unlock the bootloader. Make sure the "Yes" option is highlighted, and if it's not, use your volume keys to do so. From there, press the power button, then your bootloader will unlock and your phone will reboot back into Fastboot mode.
Now that your bootloader is unlocked, you're ready to start flashing factory images—but first, you'll have to download the actual images themselves.

Below are some links to download the factory images package for common devices. With each of the above links, simply locate your device model in the list, then download the latest available firmware on your computer. Now it's time to flash the images. The first thing you'll want to do here is extract the factory images archive that you downloaded from your manufacturer's website.
For that part, I'd recommend using 7-Zip , as it's free and works with most archive formats. Next, move all of the contents of the archive to the platform-tools folder inside of your ADB installation directory, then open an ADB Shell window in this folder. For more information on that, refer back to Step 4 above.source

Aside from that, there are two different approaches you can take when flashing the images. I'll outline both of them in separate sections below. Most factory images packages will contain a "flash-all" script that applies all of the images in one fell swoop. If you're trying to recover your device from a soft brick, this is the simplest way to go. However, it will unroot your device and wipe all existing data, so if you'd rather avoid that, see Option 2 below. But to run the flash-all script, type the following line into the command prompt, then hit enter:.
For a second option, you can flash the system images individually. This method takes some extra work, but it can be used to un-root, update, or un-brick your device without losing existing data. Start by extracting any additional archives from the factory images package. Sometimes, factory images packages can contain a series of three or four nested archives, so make sure to unzip all of them.
From there, copy all of the image files to the main platform-tools folder—in other words, don't leave them in any sub-folders. From here, there are two images that you can get rid of: These are the images that will overwrite your data and cache with blank space, so if you don't flash them, your existing data will remain intact. Of the remaining images, six make up the core elements of Android: The boot image contains the kernel, so if you just want to get rid of a custom kernel that's causing issues with your device, you only have to flash this one.
