Your boot issue sound similar to [a href=\'index.php?showtopic=34961\']mine[/a].
First off, get your scatter file from here:
http://support.planetcom.co.uk/download/partitionTool.html - I recommend that you do not check the "by default boot into linux", as that creates problems when trying to upgrade the kernel later on.
Next up, when you unzip it, use peazip (
http://www.peazip.org/) instead of Windows Explorer or 7-zip. This is where I ran into problems and I ran into the same problem you have. Windows Explorer and 7-zip choke on the IMG file.
ALSO - if you want root on android, you need to use a good text editor (notepad++) to edit "Gemini_Dual_Boot.txt" and replace where it says "boot.img" to "patched_boot.img".
Go ahead and flash using the tool. To boot into linux:
1. power off completely.
2. Then hold both the power button (Esc) and the silver side button
3. As soon as the unit vibrates for power on, release the Esc key. This MUST be released before the screen turns on. Continue holding the side button until the screen turns on.
Assuming that gets you booted into Linux, follow the instructions provided on this wiki link:
https://github.com/gemian/gemini-keyboard-a.../wiki/DebianTP2 You can essentially ignore the older "DebianTP" page as that contains instructions that have now been merged into Debian Technical Preivew 2.
