    Same here. First time I took it out the box I had to do a hard reset to get it up and running. Now it has happened again, no signs of life.

    Hello I have the same issue. Charged the device over night and today it does not turn on. Used it three times so far. It made the last software update automatically yesterday. Please help to solve the issue. 

     

    Thanks,

    Patrick

    Hey Patrick,

    Could you confirm if you were using a charger that supplies 5V at 2.5A? I would like you to also try to perform a hard reset on the Karoo : Hard reset

    If the above issue still persists, please do drop us a mail at support@hammerhead.io and we will ensure to resolve this :)

    Hi Hammerhead -- I have a Karoo2 and am a newbie user having done perhaps 4 or 5 rides with it. The unit has now gone dead, no signs of life. I have charged it using a brick and also directly into USB port, still no dice when I press and hold the B button. Guidance appreciated. Thank you.

    Hi everyone, exactly the same problem. Got my K2 this week. Charged it 2x overnight directly into the USB-c port of my laptop. Afterwords it doesn't turn on. The hard reset restarted the device.

    Hi, this has happened to my brand new Karoo 2. Used it on a few rides while the battery lasted from initial set-up and charge. Went to recharge it using the provided Karoo 2 charging cable, plugged into my laptop. It then did not turn on and was completely unresponsive. Factory reset, which rebooted it, and had to go through the entire set-up process again. Tried to charge it again as it was still low and the same thing happened. Now it shows a 0% battery screen sporadically but is still not working and is completely unresponsive. 

    Have a support ticket in for +24 hrs but still no response. Please help.

    I'm sure support will be back with you soon. Try the supplied cable together with a good quality wall adapter like for an iPad and leave it charging for a few hours. Karoo 2 seems picky about charging source and does not like fast chargers. Since I started to use the supplied cable with an iPad adapter everything has been good. Not an ideal scenario.

    Thanks for the reply and tip, Rob. I have just plugged it into a wall adapter with their cable. Going to leave it a few hours like you suggest. Perhaps it didn't like being charged from my laptop (?). Although it worked fine being charged the first time straight out the box. 

    It's a shame because it's an excellent product when it works.

    * Correction, and in fairness, Hammerhead Support replied last night. Was in my junk.

    Hi Will, good, see what happens then. Yes, it probably did not like the laptop supply. If it still doesn't start normally after a few hours then do a hard rest following the HH guide. That is what I needed to do. It should get you up and running again hopefully.

    Hi, same problem. I have had my Karro 2 for quite a while, but I though Hammerhead would be able to solve this through updates. 
    My Karro 2 have never been able to charge unless already powered on!
    After the latest update 1.212.1045.12 this still persists. However yesterday the Karoo drained the battery completely in approx 3 hours. As it was not switched off, I could not charge it. Only solution - like many times before - is a hard reset, which requires an effort with restoring settings. 
    Add to the list of problems that the sensor connection is a as bad as EVER. It loses and reconnects sensors like all the time!

    Not had any charging issues since using the iPad adapter, mine does not need to be off to charge, and not seen any sensor issues either. Sounds like you need to contact support.

    Hi Paul - have you managed to resolve your issue? I'm having the same problem and am pretty sick of dealing with it.

    I have this problem too and would like to have clear guidance on both the causes, problem and resolution. 

    • What are different scenarios and recommendations around various types of charging? (This is important when out on the road and charging options are limited)
    • How exactly is "fast charging" causing the problem?
    • What is causing the brick mode? Is it completely our of power or has it crashed/frozen? (The troubleshooting steps are very different with or without power)

    I have also had this problem. I've only used my Karoo 2 a few times, but it seems incredibly fickle about whether it will charge or not. I found it wouldn't charge from a USB port at the back of my desktop computer... so I tried a plug into the wall with a USB socket. That worked. Then tried to charge it up at the wall again after a ride, and when I came to switch it on, there was zero charge, it wouldn't power up. I had done the latest software update in the meantime... has that affected things?  So I then tried my desktop computer again... and it seems to be charging.

    This really isn't acceptable, can Hammerhead please explain what is going on, if they have identified a problem and fixed it in the latest software (e.g. so that it only charges from a low power computer?) then please tell us!

    Thanks. I've tried the supplied cable with this Apple plug... and left it charging. But when I came back it was completely drained...

    Looks like an iPhone charger not an iPad charger so different outputs.

    Thanks for that info. How would I recognise an iPad charger? do you have a pic?

    Hammerhead support: can you please respond on this question of what charger output should be.Looking at the range of Apple chargers, you can see that there are 4 different types for different iPads..

    https://support.apple.com/en-us/HT210133

    So the information 'an iPad charger' doesn't really help....

    Hi Rob

    Thanks for all your help. I worked out that you were a super-helpful user, rather than Hammerhead. Thanks for the link, not sure why I couldn't find this myself... Now I just have to work out what volts/amps different plugs and computers are outputting...

    Cheers and thanks again

    No worries Peter. HH probably should have included an adapter in the box or made it less sensitive.
