At first, we have to make sure nbd device is loaded into kernel: sudo modprobe nbd max_part= 8 Fortunately, along the support for emulated devices, there is a tool called qemu-nbd, which allows to use qcow2 images in a similar way as losetup handles normal images.

Interesting part is userdata-qemu and encryptionkey. In my case the interesting part looks like below: cache.img These real device files are called almost the same, but with. Now, they seem to be only base for the real partition image. In a good old days, inside there were all the data of the emulated devices. AVD structureīefore getting into encryption itself, let’s see quick summary of how to find emulator data and what to expect inside. Note: I didn’t need to write anything, so I didn’t try to reencrypt the partition. In this article, I will show how to gain access to emulator’s partitions from outside the emulator. What is more, latest emulators started encrypting userdata partition, even if no lock mechanism is configured and there is no way to undo the encryption from inside the Android. Unfortunately at least those emulators, which have Play Store preinstalled, also don’t have root access via adb root command.

Android emulator is really nice way to play with Android’s internals.

Cant update android studio userdata.img
