1 ) Check if all the bold sd cards files are present in Bolt SD card. If any file is missing then download all the bolt SD card from https://github.com/Inventrom/bolt-sdcard-files and copy it to the root of SD (Root means there should be no any folder inside SD card ) .
There are two options in Bolt .
a) Bolt created its own hotspot network
b) You can connect your bolt to other wifi network.
When you connect your laptop to bolt hotspot then bolt have static IP 192.168.4.2 but when you connect your Bolt to other Wi-Fi network then bolt have dynamic IP .In that case you have to find Bolt Ip using Download Advance IP(www.advanced-ip-scanner.com) Scanner software or in case Advance IP scanner is not working then you can download Fing APP( https://play.google.com/store/apps/details?id=com.overlook.android.fing&hl=en ) in your mobile .(Make sure your bolt and mobile should be connected on same network. )
I will suggest you to connect your bolt to home wifi network. you can directly connect your bolt to other Wi-Fi network. There is one file inside with name bs.txt . Inside bx.txt you will find two varibles ssid(Wi-Fi name) and password(Wi-Fi password). Type crendetials in front of those varibale. Insert your bolt Sd card in bolt and restart . If blue led becomes stable means your bolt is connected to your home wifi/hotspot.
