I picked up a used K2, and installed it. Red and black directly to battery, and yellow to a switched power source that goes on with the ignition. I put a brand new Sandisk 256GB in, and the firmware is the latest version.
Strange behavior is that there is no blue light on the DVR which would illuminate the "wifi icon". I am able to connect my phone however, as it found the SSID and accepted the default password of "12345678". I went into the settings menu to format the card, and it appears to do its thing, and reboot the DVR. However when I reconnect my phone, it just says "Card Error". Tried again and again but no luck with the brand new Sandisk. I tried three other cards that work fine on my GoPro, and no luck.
I have even replaced the power supply, to be sure. I'm baffled at this point, and would love to get some suggestions from the good folks here.
Thanks!
Hi Richard,
after formatting one sd card in the DVR, could you please insert the sd card into your pc and check what file system format it uses? And whether the sd card is useable at the pc or not?
There is special firmware for the K2 which enables a logging feature. With this the K2 will write a log file on the sd card each time it runs. Of course this would not work if the K2 can not access the sd card. But lets give it a try.
Take a smaller sd card (less than 256 GB) and format it on your pc in FAT32 format
Download the V71_with_Logging firmware from my Dropbox. https://www.dropbox.com/sh/b5cqpgzwd72nxno/AABmGMfSDhq9aqBAnZ6YkTZAa/K2-V71_with-Logging.bin?dl=0
Rename the file to K2.bin and put it into the root folder of the sd card.
Insert the sd card into the DVR, fire it up and wait for the update to finish. It should reboot after the firmware update.
After the update/reboot you should find some log files on the sd card. Most of them are dump files and useless for us. But there will also be a text file for each run of the DVR. These file(s) are named by the time and date the DVR started. These are the console logs and they could help to check what is going on.
