(or you do it yourself)
Great, you understood how it works.
So go on, read the DryOS-thread, stick to the tutorial I posted on the first page and get it working.
The current a720-source is included in trunk now, so
get it. You already have the DryOS-signatures, just make sure you use the
current ones.
Here's something to play for the A650-owners: A test of a universal dumper that writes the firmware to the SD.
It's just a test but was confirmed to work with a A720 and an A710.
Important: This dumper writes directly to the card, no file is created, so use an empty card or you might lose data!
If writing works, the dump starts at sector 1024 on the SD (
not the partition), look for the string "gaonisoy", if it's there, the dump was successful.
Further information and a link to the diskboot.bin that worked with my A720 in
universal dumper - one more idea.
Cheers.
