|
||||
```
|
||||

|
||||
|
||||
```
|
||||
sudo vim /etc/udev/rules.d/20-mm-blacklist-mtk.rules
|
||||
```
|
||||
```
|
||||
ATTRS{idVendor}=="0e8d", ENV{ID_MM_DEVICE_IGNORE}="1"

|
||||
```
|
||||

|
||||

|
||||
cd FlashToolLinux
|
||||
sudo ./flash_tool.sh
|
||||
```
|
||||
|
||||
## Prepare firmware
|
||||
1. go here : http://support.planetcom.co.uk/partitionTool.html
|
||||
2. select gemini version (4G or wifi)
|
||||
3. boot 1 : select Sailfish (no this is not an error)
|
||||
4. move cursor to reserve all partition to linux
|
||||
5. download scatter file
|
||||
6. download base firmware
|
||||
7. boot 1 : select android standard
|
||||
8. boot 2 : select debian
|
||||
9. move cursor to reserve partition for debian & android
|
||||
10. download aditional debian firmware
|
||||
|
||||
*so you have 3 files :
|
||||
-scatter file for selfish os
|
||||
-base firmware
|
||||
-debian firmware
|
||||
|
||||
*create a folder
|
||||
-dezip base firmware inside
|
||||
-dezip debian inside
|
||||
-copy scatter file inside
|
||||
|
||||
*download Notepad++ (or something like this and make sure the file Line ending is set to Unix (LF))
|
||||
|
||||
*go inside created folder
|
||||
-open scatter file with notepad++
|
||||
-search for ALL sailfishos_boot.img and replace it with debian_boot.img. Save the file
|
||||
|
||||
*open flashtool
|
||||
-go to « download » tab
|
||||
-download-Agent : should be set to the file MTK_AllInOne_DA.bin (which is located in the FlashToolWindows or FlashToolLinux folder).
|
||||
-scatter loading file : choose the scatter file that you have modifyed just before
|
||||
|
||||
all the files in colums must be checked and location not empty
|
||||
|
||||
[1.1.3] BACKUP NVRAM
|
||||
-go to « readback » tab
|
||||
-click « add » button. A row will appear in the table under.
|
||||
-click « Read Back » button
|
||||
connect your PC to the left end USB-C port on your Gemini and restart the Gemini. Once booted, the flash tool will detect the unit and will write the NVRAM partition on a file on your hard disk called NVRAM0. It’s a good idea to keep this file as a backup, together with the customised Scatter file.
|
||||
|
||||
[1.1.4] FLASHING FIRMWARE
|
||||
-click « Download » tab.
|
||||
-drop-down list : select « Firmware Upgrade » option from the drop down menu
|
||||
-click big « download » button
|
||||
-connect your PC to the left end USB-C port on your Gemini and restart the Gemini. Once booting, the flash tool will detect the unit and will start flashing the device with the selected firmware.
|
||||
-wait the end of flashing
|
||||
-deconnect gemini of pc
|
||||
|
||||
|
||||
[2] LAUNCH DEBIAN
|
||||
-press esc button a long time, and wainting for the login page
|
||||
-on login page, select your country in « layout » drop-down list and enter password « gemini » under the username
|
||||
|
||||
|
||||
[3.5] UPDATE
|
||||
VERY important -> do not make apt update & upgrade before THIS. If not, you will break all the file system.
|
||||
[3.5.1] ADD REPOSITORY ARCHIVE KEY
|
||||
-in qTerminal, on root account enter :
|
||||
$ wget http://gemian.thinkglobally.org/archive-key.asc
|
||||
$ apt-key add archive-key.asc
|
||||
$ apt update
|
||||
apt install apt-transport-https
|
||||
$ apt upgrade
|
||||
|
||||
[3.5.3] MAJ DEBIAN 9 to 10 & Security updates
|
||||
[3.5.3.1] SECURITY UPDATES
|
||||
-in qTerminal, on root account enter :
|
||||
$ nano /etc/apt/sources.list.d/multistrap-debian.list
|
||||
-you must have :
|
||||
deb [arch=arm64] http://http.debian.net/debian stretch main contrib non-free
|
||||
deb-src [arch=arm64] http://http.debian.net/debian stretch main contrib non-free
|
||||
-add :
|
||||
deb [arch=arm64] http://security.debian.org/debian-security stretch/updates main contrib non-free
|
||||
[3.5.3.2] INSTALL SOME SOFTWARE THAT ARE NOT IN THE STRETCH VERSION
|
||||
-add :
|
||||
deb [arch=arm64] http://http.debian.net/debian stretch-backports main contrib non-free
|
||||
|
||||
## Disable Wifi MAC generation
|
||||
|
||||
Since Android is generating a new mac address for your wifi interface at every reboot and Connman is storing the mac address in its services you would need to enter your wifi passwords every time you reboot.
|
||||
|
||||
Fortunately there is a way to lock the mac address.
|
||||
|
||||
install hexedit: sudo apt install hexedit
|
||||
sudo hexedit /nvdata/APCFG/APRDEB/WIFI and set a mac address in bytes 04-09 (mind that the base is 0, so it starts at the 5th byte) of the first row (0)
|
||||
set the i attr on the file: sudo chattr +i /nvdata/APCFG/APRDEB/WIFI
|
||||
|
||||
This will lock down the mac address.
|
||||
|
||||
## WiFi eats battery whilst sleeping
|
||||
|
||||
You need to install connman-plugin-suspend-wmtwifi to avoid this:
|
||||
|
||||
sudo apt install connman-plugin-suspend-wmtwifi
|
||||
|
||||
Turns out this plugin just stops the repeated re-connection's to wifi. It still eats lots of battery.
|
||||
|
||||
## Libreoffice
|
||||
|
||||
Due to some peculiarity in the system image creation by multistrap our libreoffice installs get their diverts muddled, if you get an issue on upgrading with it complaining about libreoffice do the following:
|
||||
|
||||
cd /var/cache/apt/archives
|
||||
sudo dpkg --force-all -i libreoffice*.deb
|
||||
|
||||
This basically forces a reinstall of all the libreoffice debian packages.
|
||||
|
||||
## i3
|
||||
|
||||
sudo apt install i3
|
||||
|
||||
## Non-latin characters and meta mepped keys
|
||||
|
||||
For keyboard that have both Latin and native characters you pick your language variant, eg for Gemini Russia (Cyrillic):
|
||||
|
||||
setxkbmap -model planetgemini -layout ru
|
||||
|
||||
But there is a bug in symbols mapping, so you need to fix it manually:
|
||||
|
||||
sudo vim /usr/share/X11/xkb/symbols/planet_vndr/gemini
|
||||
|
||||
|
||||
Replace word `backslash` to `slash` in lines 377 and 388 with:
|
||||
```
|
||||
- key <AC09> { symbols[Group1] = [ Cyrillic_de, Cyrillic_DE, backslash, Lstroke ] };
|
||||
+ key <AC09> { symbols[Group1] = [ Cyrillic_de, Cyrillic_DE, slash, Lstroke ] };
|
||||
|
||||
|
||||
- key <AC09> { symbols[Group2] = [ l, L, backslash, Lstroke ] };
|
||||
+ key <AC09> { symbols[Group2] = [ l, L, slash, Lstroke ] };
|
||||
```
|
||||
|
||||
|
||||
You then have two groups working with simultaneous pressing of both left and right shift keys being how you swap between which is the active group.
|
||||
|
||||
|
||||
#Disable cert check for repo
|
||||
|
||||
sudo vim /etc/apt/apt.conf.d/99disablesslcheck
|
||||
|
||||
Acquire::https::gemian.thinkglobally.org::Verify-Host "false";
|
||||
Acquire::https::gemian.thinkglobally.org::Verify-Peer "false";
