Ok. So i tried to make it as easy and safety as possible.

First official notice: I doesn't recommend anyone not familiar with linux systems or interested in android or eDGe development to apply this update. It doesn't give you any improovement exept for ability to run apps that required root access. Also you agree that I didn't take any responsability for any problem coused by this update or by any apps or action used root access incorectly. Also this can void your warranty.

Now fun begins:
1. You'll need to have "Better Terminal Emulator Pro" installed first. You can get it here http://www.magicandroidapps.com/wiki...l_Emulator_Pro
2. Download this file http://www.filefactory.com/file/b24168h/n/update.zip
3. Put update.zip to the root of your SD card.
4. Press and hold "rotate" and "menu" buttons while turn of EE using power button. You need to hold "rotate" and "menu" for about 7 seconds to start firmware update process.
5. Whait. EE will reboot several times (just as when you aply any update).
6. Android will load as usuall.
7. Run Better Terminal Emulator Pro and type this commands:
suandr
ash
the first one will grant you root, while second give you advanced shell with root permissions.
That's all, but to start development we will go futher 'cos no software, or hardware keyboard on eDGe support some special characters which required to use shell. Also I was unable to enable adb 'cos adbd say unable to bind to port 5037... nevermind...

8. Make sure that you have wi-fi connection (to local router at least), in Better Terminal Emulator Pro type this commands:
netcfg
busybox telnetd -l /bin/sh
9 On your computer run your favorite telnet\ssh emulator (Like Putty http://www.chiark.greenend.org.uk/~s.../download.html) and start telnet connection to IP listed in output of netcfg (I got this mlan0 UP 192.168.137.9 255.255.255.0 0x00001043
so my IP: 192.168.137.9).
10. You got remote shell with root. You can type in ash, to get advansed shell.
11. ... you're welcome

I doesn't have much time to program something usefull (at least now. I tried a few things. But very unstable) So I hope that there will be some people who can (for example compile Firefox for e-ink screen) or sync both displays...
