[Q] Moto G 2nd Gen crashes while booting. topic

Two days ago I got my moto g 2nd gen battery drained to 0%. I managed to escape from bootloop and charge battery to 100%, but still I can't power it up. When I'm booting my moto g it shows motorola logo, three "worlds" (these "worlds" which are shown when booting, you know) and then I see black screen. . I would be very grateful if you would help me fixing that issue. I wiped the cashe and factory reseted from recovery mode.

Documents app crashes when selecting sd card root for 3rd party write permissions. topic

HTC ONE (M8) Troubleshooting
I recently updated my HTC one M8 (India) to 5.0.1 Lollipop (Stock HTC).
3rd party file managers require me to select SD card root directory for write access. Accordingly it takes me to the documents app. Then when I slide from the left it shows Internal storage and a blank title showing the SD card. When I select the SD card, the app (documents) crashes. And I am unable to select the root directory, and therefore I cannot use 3rd party file managers. Please Help!
