Faulty Module?

Hi, last week I bought a Nissan Leaf 2015 and it comes with ovms, parked at my garage and connected to wifi/GSM it works, but after a short trip the module resets itself and I need to configure everything again, what can be wrong? I've tried disabling GSM, without CAN write with same result, I've installed a new SD Card and tried to backup my configurations but I cannot create files under /sd/backups, or create more logs apart from this:
