How to access PC disk from adb shell?
Lol, I just set everything to 777 with su:


x86_64:/ $ su
x86_64:/ # chmod 777 /data/mi 
misc/     misc_ce/  misc_de/
x86_64:/ # chmod 777 /data/misc                                                             
x86_64:/ # chmod 777 /data/misc/                                                            
adb/              cameraserver/     media/            shared_relro/     vold/
audioserver/      dhcp/             net/              sms/              vpn/

bootstat/         keychain/         profman/          update_engine/
boottrace/        keystore/         radio/            user/
x86_64:/ # chmod 777 /data/misc/key                                                         
keychain/  keystore/
x86_64:/ # chmod 777 /data/misc/keystore/                                                   
x86_64:/ # chmod 777 /data/misc/keystore/user_0/                                            
x86_64:/ # chmod 777 /data/misc/keystore/user_0/*                                           
chmod: /data/misc/keystore/user_0/*: No such file or directory
1|x86_64:/ # chmod 777 /data/misc/keystore/user_0/*                                         
chmod: /data/misc/keystore/user_0/*: No such file or directory
1|x86_64:/ # 


And it worked :)))
