Coby Kyros mid 7015 stuck at logo screen, how do i fix it?

my kyros mid 1024 not charging i nick fix

Either the power cord, battery, or motherboard is dead.

Bring it to where you bought it and test it with a new power cord. If that doesn't fix the problem then have them fix it.

Before we begin you will need to have the following ready. ? The Coby Kyros with a battery level of 30% or more, the USB cable and an empty micro SD card with a minimum of 4G. The Micro SD card should be inserted into the Kyros. Start by going to our website www.cobyusa.com to download the zip file to your computer. The file can be found on the main page for the MID7015. It is titled "UPDATE.ZIP". It is important that you do not UNZIP the file.

Once file has been downloaded to your computer, turn the Kyros on and connect the unit to the computer via the included USB cable. At the top of the main page Go to the navigation bar and scroll down. A menu will open with several USB notifications.

Click on the External USB connection. This connection refers to the inserted SD card. A new menu will appear Click on MOUNT. Once complete your computer should recognize the Kyros device. A screen will open and show the Removable Storage drive. If this window does not open, please go to the start menu of your computer and select computer or my computer. There may be several drives shown. Please choose the one that corresponds to the SD card, it should show as empty. Open the drive. Now you may drag and drop the ZIP file into the removable storage drive. This process will take approximately 1 minute to complete.

When complete Go back to the Main Screen of the Coby Kyros Once again go to the top navigation bar and Turn off the USB Storage. Another window will appear with a turn off message. Make sure to click on this as well. Disconnect the Coby Kyros from the USB cord attached to the computer. Then Press the Power button, it will again prompt you to power off from the main screen twice.

Wait 5 seconds. During this time locate the power button and the return button. Press both buttons at the same time. Continue to hold the buttons down until you see the warning triangle and android logo. Once the symbols appear you may release.

Press the return button again. The reboot section will appear. You will use the Home and Menu keys to scroll through this section. The Home key scrolls up and the Menu key scrolls down.

Scroll down to Wipe data/factory reset. Press the return button to select. Scroll down to Yes and hit return. The Kyros will notate the Data wipe is complete.

Scroll down to Apply SDcard and press return The Kyros will notate Install from SD card complete. This will take approximately 1 minute .Select Reboot system now and hit return key

Congratulations you have just updated your Coby Kyros

Thank you for visiting FixYa.

go to other WI-FI hotspot and check if you have the same problem.... otherwise their maybe a problem on your tablet or wi-fi module.

Mine does that to but all I ever do it just hit the reset button on the back and it turns back on.

I would first try a different power cord/brick and make sure that isn't the issue. If that still doesn't work then you may have a broken port on your Kyros. In that case try and get a warranty replacement and if that isn't feasible you will most likely have to pay for the repair. If you recently dropped it while it was plugged in, that may have broken the connection between the port and the device.
