[DISCONTINUED][UNOFFICIAL] CM-12.1 [22 Nov 2016]

[ggow]

IMPORTANT NOTICE​

:
As many of you know, the CM-12.1 branch will not be supported in the new LineageOS fork. And many of the new Google security patches are difficult and fiddly to back-port as they are now geared towards Marshmallow and Nougat. So as a result there will be no further updates to this rom.

Instead my focus will now be Fire Nexus ROM for this device.

Also looking at possible ways to get later android versions on the device. Will let you know if there is any progress later.

Thanks for all the support :good:

Frequency Asked Questions

Question 1:
How do I adjust the keyboard sound level?

Answer:
- Go to settings -> Languages & input -> Android Keyboard -> Advanced -> Keypress sound volume
- Then adjust the slider to your preferred level

Question 2:
Why does the screen image seem stretched or distorted?

Answer:
- The actual pixels in the Fire's LCD are not perfectly square
- That causes some distortion. It is particularly noticeable with round icons & when the screen rotates.
- This issue also effects the stock amazon OS as well as all custom roms.
- It is not yet known if this will be fixable in software (my current thinking is probably not)

Question 3:
Why is my brightness slider not working?

Answer:
- Try installing Brightness Level and use it to change brightness. After doing this brightness slider should work fine and you can remove Brightness Level.

Question 4:
When installing Google Play Games and Google Calendar I get error -505?

Answer:
- Install older versions from apkmirror then update from Google Play Store.

Question 5:
How do I use CIFS?

Answer:
See the guide here

Actual CM12.1 on the Fire 2015? So, a premium device for $50 with CM12.1? Awesome! Might have to pick one up now... I'd guess I don't have to fastboot each time I power on right? Just the first time to get CM/TWRP, then have CM/TWRP install+boot CM12.1, then I can get CM12.1 without fastboot?

- You will have to fastboot each time
- It's all in the OP including the reasons why this is the case at the moment.
- It's not ideal - but thought I would share what I have so far
- I am looking into solutions for this now.

Once booted into CM12.1 we can make general system configuration changes, install apps, etc, correct? And will changes be be retained if we need to reboot (through fastboot)? If so, where will CM12.1 files be stored?

- Yes customise as much as you want - all will be retained.
- Your data and OS is stored on the /data and /system partition respectively
- The only thing you have to reload on a reboot through fastboot is the modified_boot.img which won't affect anything else.

Awesome work @ggow!. @diegocr and me have been working on bring slimrom to this device. We are having some issues with WiFi and bluetooth. Would you mind to share your device and vendor for cyanogen?.
Thanks.

Hi csolanol,

- I am in the process of updating my bibucket with the most recent changes
- Having trouble with bluetooth too.
- Wifi is working fine - I got it working like this:
- put this in your device tree
- then add this to your boardconfig.mk:

[INDENT]WPA_SUPPLICANT_VERSION := VER_0_8_X
BOARD_WPA_SUPPLICANT_DRIVER := NL80211
BOARD_HOSTAPD_DRIVER := NL80211
BOARD_WLAN_DEVICE := mediatek
BOARD_WPA_SUPPLICANT_PRIVATE_LIB := lib_driver_cmd_mt66xx
BOARD_HOSTAPD_PRIVATE_LIB := lib_driver_cmd_mt66xx
WIFI_DRIVER_FW_PATH_PARAM:="/dev/wmtWifi"
WIFI_DRIVER_FW_PATH_STA:=STA
WIFI_DRIVER_FW_PATH_AP:=AP
WIFI_DRIVER_FW_PATH_STA:=P2P[/INDENT]

- Then add this to your device.mk or equivalent

[INDENT]# wifi
PRODUCT_PACKAGES += \
	lib_driver_cmd_mtk[/INDENT]

- Do not include the propriertary bin/wpa_supplicant when building otherwise you will get a build error
- Instead copy it into your ROM after building.

- Hope this helps for now.

- Yes, that was me who said that but Amazon have changed things since then.
- On the HDX at the time they were not enforcing an selinux policy
- Now that Amazon are enforcing it cannot work in the same way at least for the moment until a workaround is found.

Thanks, I will wait bitbucket update :good:

- Did you guys find a way of been able boot Slim without having to fastboot a boot image each time?

- I built my ROM without block based image generation
- This means you can extract the ROM and use the proprietary-files.txt with the extract-files.sh to re-generate the vendor tree
