This is the normal LineageOS loading screen, which I had until yesterday:

**Problem**: Since yesterday, only one circle is going from right to left, forever. In other words, it never reaches the 3 circles, and my Nexus 5 has become useless.

After reading https://android.stackexchange.com/questions/88662 I tried pressing Power/Volume- at the same time for 30 seconds. Result: It makes the recovery screen appear for less than a second, then the screen turns black. Pressing the same buttons during the earlier "white Google+unlocked lock on black background" screen results also results in a black screen, followed by this boot-loop:

1. white Google+unlocked lock on black background, for a few second
2. black screen
3. Vibration
4. Back to step 1

**Question**: How to at least get the content of my Nexus 5's storage memory? Or even fix it if possible?
