Transferring Files

 * How to transfer files into the GCW Zero using FTP:


 * 1) Download a FTP client (Filezilla is a nice one).
 * 2) In your GCW Zero, go into Settings > Network and select between setting a random password or login without password.
 * 3) Connect the GCW with the USB cable and start your FTP client.
 * 4) In the "Host" field (upper left in the Filezilla window) type 10.1.1.2 and press Enter. You might also need to enter a username/password if you chose it in the Network settings of the GCW Zero. Password is randomly generated. Username is "root".
 * 5) You should be now be able to access the folders of your GCW Zero and drag and drop files into the FTP client window.
 * 6) To install OPK apps, simply drag and drop them into the /media/data/apps/ directory. Gmenu2x will autodetect them and create a shortcut in the appropiate section.


 * I can't connect to my GCW Zero using FTP through USB:

If you can't connect through USB, it's likely that your OS failed to automatically install the appropriate drivers.

Windows 7

 * 1) In Windows, go to the Control Panel > Device manager.
 * 2) Once there, locate a device with a yellow "!" sign. It will probably be in the Network adapters area.
 * 3) Right-click it, and select "Update Driver".
 * 4) Select "Manual install".
 * 5) Select "Choose from a list of drivers", then "Network Adapters".
 * 6) In the Vendor list, select "Microsoft Corporation".
 * 7) Select "Remote NDIS Compatible Device" and install that driver.
 * 8) It should now successfully connect in your FTP client app.

Troubleshooting
While the reason for this issue is as of yet unknown, the solution is simple:
 * White or distorted screen
 * 1) Turn off the device (if possible), then hold down the reset button (located in a hole labeled "RESET " in the lower side of the device) pressed for about 40-50 seconds. Make sure no external power source (USB or DC charger) is connected. Upon release, the screen should get back to normal.

Device being stuck on a black screen can mean one (or more) of the following issues:
 * Black screen and no boot process visible
 * 1) Missing or damaged bootloader/bootloader partition
 * 2) Missing or damaged kernel image/kernel partition

You can attempt to boot a backup kernel image (if available) by booting the device while holding the key pressed. In case this doesn't solve the issue, manual firmware flashing might be necessary.

The most probable issue is that one of the OPK files was corrupted (usually during a file transfer). Gmenu2X is not able to parse it and refuses to proceed further. A solution is to remove the OPK file in question (No output on the screen should not impact the file transfer capabilities).
 * Black screen after a successful, visible boot process

This error means that the rootfs.bin image is missing or damaged. You can attempt to boot a backup rootfs image (if available) by booting the device while holding the key pressed. In case this doesn't solve the issue, manual firmware flashing might be necessary.
 * The device is stuck at "Error: cannot mount/dev/loop0/on root"


 * Firmware update failure
 * 1) Check if the internal memory is not full. The firmware update requires at least 60MB of free space and will fail on insufficient memory available. In case of firmware update failure, your system will be restored to the currently running firmware version.

There are two separate issues that might cause this:
 * External microSD card is not detected
 * 1) The driver had issues detecting the card. Please leave the card inserted and reboot the device to increase the change of it being detected. Please also make sure there is no dirt or other residue that would prevent the pins from making contact.
 * 2) The filesystem type was not detected. Please note that only VFAT (FAT32) and EXT* filesystems are supported. NTFS and ExFAT are not supported due to patent licensing reasons.
