Help booting into linux

[YourTech John]

I'm attempting to flash linux for dual boot. My Gemini was from the second batch which arrived May 2nd.

There are two guides I've read through and followed.

Everything seems to follow along just fine, until I attempt to boot into Linux.

> Press Esc (On) for around one second to turn ON the unit and at the same time press and hold the side button until the screen turns ON to boot into Linux. You should release the Esc (On) button before the screen turns ON, but you must keep the side button pressed until you see the turning ON. When the screen turns ON you can release the side button, and the unit will boot into Linux.

When I turn on the phone normally. I get a splash screen showing Tux, which indicates success with flashing. After 2-3 seconds, it says "Powered by Linjux" at the bottom, then that screen is replaced a second later by the normal one that says powered by Android. At that point, it boots into Android.

If I turn on the phone and hold the side silver button, the first Tux splash screen comes on for 3-4 seconds, then the screen turns off for 2-3 seconds, then comes back on. On the second go around, to boots "normally"  into android as described above.

If I hold the silver down button constantly, it just seems to keep rebooting. Once I release it, it will then cycle into Android.

Any suggestions?

Hi John,

Hopefully someone who has recently received their Gemini (I am still waiting for mine!) has tried to do this also, and can comment accordingly.

It would certainly be good to have the dual booting option working correctly.

Good Luck!

Understand what you're going through....it is a bit tricky...took me a few times of trying to get the hang of it.

Unfortunately, different guides have different instructions for turning on to different OS's....apparently, it changed at some point, and some guides need updating to be consistent with current situation.

After various attempts to boot up Debian, I've found it works for me to click on the 'Esc' key, I hear the vibrating tone, as I press and hold the side silver button for about 2 seconds....and then let go....

You should see the splash screen that says 'powered by linux' below the graphics....if so, then it should boot up to Debian.

Hope this helps.

It was a bad flash. tl;dr - use peazip on windows instead of 7-zip or windows explorer.

I discovered that windows explorer and 7zip are failing CRC check on debian.img.  Linux unzip doesn't seem to have a problem.

    testing: Gemini_Debian_TP/debian.img   OK

For reference:

Size is 6.6Gb.

When unzipping with 7-zip, it only exacted about 2.5G before the CRC failure and stopping. The window with the error message was hidden behind other windows.

I then downloaded peazip and that extacted the files correctly.
