leader Impression I10-50 firmware update
In order for the firmware update to be completed successfully, u need to first format your sd card via sd card reader or your tablet as follows:
Plug in the tablet via usb to your PC or load your card reader with sd card
Then select and left click whatever removable disk drive your tablet shows up
Select format and make sure the file system is set at FAT32
Select start, your sd card should begin formating.
Once complete, then u follow the 13 steps, but since you have already started step 1-13, just press your -volume and power buttons at the same time (steps 11 and 12 again) and it should update your tab. Be sure to do it twice as far as the volume and power button go so the update completes successfully.
