I Have Linux machine ....:dancing2:
How I Can flash new one with sdcard >>????
Ok, but then I don't know where the problem is... If you know how to actually use linux, all is written in amlogics guide. All you have to change is to use your u-boot-aml-ucl.bin file instead of u-boot-aml.bin from the guide.
What you have to do is to open terminal and copy u-boot-aml-ucl.bin to beginning of sdcard with dd command. After that you have to delete all partitions on your sdcard with fdisk utility and create new primary partition of type fat32 which will start from 2nd or 3rd sector. Changes you have done write to your sdcard and format newly created partition. Copy all upgrade files to your sdcard's newly created partition and insert it into your box. After that do standard recovery procedure using reset button on the back.
