I have been all over looking through forums and reading many of tipsters posts and have tried to upgrade the Maylong 105's ROM through the sd card. I am very computer savvy and have updated three other tablets of mine successfully. So I was wondering what the heck is going on with the 105 as it will not respond to the sd card during boot up in order to upgrade the rom. It does read the card as I can see files on it through the file manager, but it does not see it during boot up. I used 2 different cards, both class 4, one 2GB and one 4GB (brand new) with no luck. I tried to reformat each to FAT32, and still nothing. Can I install the files in the Maylong root and then restart it to upgrade and then remove the files and reboot? Any help would be greatly appreciated!!! Thanks!
