So I have a Hero 4 with a broken lens. I decided to try to fix it myself tonight I stripped it down following a YouTube video and swapped the lens out. After reassembly couldn't get it to power up, after checking all the cable/connections all was well so I tried again but still nothing only the charging light. Undeterred I decided to try a hard boot which has been known to jump start unresponsive GoPros which involved applying power, holding all three buttons and inserting the battery. To my delight the GoPro powered up and everything seemed to work including a short video. But then I realised the front mode button would not power off the GoPro or change mode. Despite this it records and the shutter and side buttons work. I pulled the battery to shut it down and then tried to power it up again but the front button is still unresponsive. I managed to kick start it again and had the same control as before but can't change mode or power down.
Does anyone know how I can fix this ? I've cleaned the contacts of the mode button and I feel it clicking but it has no effect. Can anyone help me debug this or point me to the connection that is faulty
