I'm no expert, but if you're getting the logo still then sounds like the bootloader is still fine. Try re-flashing the Android NAND again, sometimes it doesn't work first time, or try downloading one from a different source in case the one you got was corrupt/incorrectly labelled. When I googled it I found at least 2 different download sources for the Android NAND of your system. If still no luck then I'd recommend posting your issue on an Android forum as you'll have a greater chance of getting a resolution.
Very thank you !!! I try it's here, getting success put to help others!
