HI: Please check on the MD5 checksum of Android images you downloaded, and to see if the LCD-cable is in right position.

Tp? Touchpanel? I’m using the lemaker 7" LCD module, android 4.4 LCD os burned to the sd card using Phoenix card, I’m not getting any messages the screen turns on an just stays a blank white screen

16

How do I check the md5 checksum?

17

do u know if it starts up into the os? maybe u can try find it in the network than we can atleast know that the system is not faulty, and thats it is a screen issue

18

I believe it does as it only turns on with the android 4.4lcd os but it just remains a blank gray/white screen

HI: It seems to me that the actual root cause is that you’re not using BPI 7" LCD module. As a matter of fact, we don’t know the spec. of your LCD, therefore we’re afraid we 're not able to give you suggestions. Maybe you’d love to consider purchasing a BPI 7" LCD module. http://www.aliexpress.com/store/product/New-100-original-high-quality-Banana-Pro-Pi-7-inch-LCD-Display-Touch-Screen-Raspberry-Pi/302756_32339310545.html

I am using a banana pi 7" LCD module it’s the lemaker version not the bpi version, it’s made for the banana pi/ banana pro or the banana pi m1/m1+ which the lvds should be the same as the banana pi m2
