Works like a charm now, thanks to a comment on the xda forums
I absolutely take no guarantee, but here is a step-by step guide:
INSTALL CYANOGENMOD 11 M 10 (CM FP 0.2):
Requires:
- Additional SD card
- FP1 repartitioned with OS Version 1.6. FP1U is reported to work AS well.
- Important! Back up all your data with Titanium Backup, backup your recovery file + Backup all your contacts and anything else important somewhere, you will need it, as all data will be erased in the process.
Download on your (Windows) Computer:
- MTK 6598 driver (don’t know if that’s really necessary though…)
- MTK Droid Root & Tools v. 2.5.3
- [FP1 KitKat Recovery Image][4] (FP1U Users probably need the 0.2 version + alter filenames [in this guide][5])
- [Cyanogenmod zip file][6] + put it on your sd-card
- If you want GAPPS then also get the [GAPPS.zip for Cyanogenmod][7] + put it on your sd-card
Install on phone:
- [Rom Manager 6.6.3.7 ][8]
Procedure:
- [Install MTK 6589 driver][9] (again no idea, if that’s necessary)
- Install + Open up [MTK Droid Root & Tools v. 2.5.3][10] (allow USB Debugging von the Fairphone in System Settings, then connect your phone to Computer via USB)
- Root phone in MTK Droid Root & Tools
- Backup phone with MTK Droid Root & Tools
- Install the recovery.img on phone: Open adb console in MTK Droid Root & Tools and type: (FP1U users have to use a different .img and filenames consequently. For more on that step see [installation instructions])[12]:
adb push cwm-fp1-kk.0.1.img /storage/sdcard1
adb shell
dd if=/storage/sdcard1/cwm-fp1-kk.0.1.img of=/dev/recovery
- Unplug device and “Reboot into Recovery” with [Rom Manager 6.6.3.7 ][13]
- In the recovery menu: (use lower volume key to navigate and upper one for Enter command)
->wipe data / factory reset
–>Wipe user data
->Install zip
→ choose zip from /storage/sdcard 1
—>cm-11_FP1-ota-UNOFFICIAL-FULLOFBUGS-0.2.zip
->Reboot phone now (this can take a while)
Now you have Cyanogenmod! For Google Apps:
8) Go to Settings → Developper options → tick Advanced Restartmenu
9) Power → Restart → Restart in Recovery mode (use upper and lower volume key to navigate und Power button to select / Enter)
→ Install zip
→ choose zip from /storage/sdcard 1
—>gapps-kk-20140606-signed.zip (different filename possible, depending on what Version of GAPPS for Cyanogenmod you are using)
->Reboot
-
EDIT: (20.09.2014) Updated instructions to CM FP 0.2
