    Yesterday I Installed android 5.1 on my Samsung Galaxy S II with help of a tutorial video( The ROM I installed CM 12.1 Android 5.1.1) it all worked fine downloaded some apps like Pokemon go and it still worked fine until a update of cyanogenmod came up so I installed it restarted the phone, then the wifi connection started to do weird so I went to updates to see if there was an other update which I might have missed. There was one so I clicked it downloaded the update then I saw it was an old update. When the update rebooted the phone it didn't wanted to start. Tried to get in recovery mode but that didn't work.

    When I start the phone I get the start screen
    Samsung Galaxy S II
    GT-I9100
    Yellow triangle with a exclamation mark
    then the screen turns black and nothing happens

    When I try to charge the phone
    the screen stucks on the battery loading image

    Hopefully someone has any ideas how to fix this problem and get my phone on and working again
