If you appreciate my work and would like to support me with a small donation you can click on button.
If every happy user of this rom would just donate something I could invest more time in all these Android projects.

Issues and possible workarounds

* Accelerated video playback is supported by MX Player in HW+/HW mode and pretty much every file will play, try both playback method because it depends on the video codec; I noticed that HD videos plays better in HW+ mode while SD (XviD for example) play better in HW mode. For a better audio support (included DTS playback) have a look here.
* HDMI shows a picture but it doesn't fill the TV screen entirely.
* Probably other things...

Features

* USB GPS support (cp210x and pl2303)
* Xbox 360 gamepad support (xpad)
* PS3 USB gamepad support (hid-sony)
* Generic / chinese (Pantherlord / GreenAsia) gamepads support (hid-pl and hid-gaff)
* OpenVPN support (tun)
* Veno congestion control algorithm
* USB audio
* USB bluetooth (It supports only CSR devices, they can be identified typing "lsusb" from an app like "terminal emulator": the supported device will be present with an entry like "Bus 001 Device 002: ID 0a12:0001" ("0a12:0001" is the supported VID:pID). Do not boot with the bluetooth plugged in; plug it once you booted to android.)

Instructions

* You need TWRP to be able to flash this rom. Read the linked thread for instructions.
* Put rom (cm-10.1-$DATE-UNOFFICIAL-spark.zip) and gapps (gapps-jb-$DATE-signed.zip) files inside internal or external sdcard.
* Turn on the tablet in recovery mode as explained in TWRP thread.
* If this is your first install select "Factory reset" from "Wipe" menu.
* Flash rom (cm-10.1-$DATE-UNOFFICIAL-spark.zip), gapps (gapps-jb-$DATE-signed.zip) and, if you're installing this rom on a device that is not the Spark, the required compatibility zip.
* Now select "Reboot".
* Enjoy CyanogenMod 10.1!

Changelog & download links

FAQs

* If your devices doesn't have a volume rocker you can install one of these apps to control volume from the notifications: Volume in notification, TrayVolume
* WiFi now can stay enabled with display turned off. Note that if WiFi is enabled the tablet won't enter deep sleep so if you're more interestead in battery life instead of an always on WiFi change policy (on "Advanced" WiFi settings) from "Always" to "Never" and select your preferred WiFi timeout.
* Internal memory is mounted at /storage/sdcard0, external sdcard is mounted at /storage/sdcard1. If you wanna swap them (and make primary your real microsd) just edit "persist.sys.vold.switchexternal=0" to "persist.sys.vold.switchexternal=1" in "/system/build.prop" file

* WARNING: before flashing this build you HAVE to flash stock SDK 3.2 using Phoenix Suit and answering "yes" to the format prompt, after that install the new TWRP for SDK 3.2 and proceed. You can do a nandroid backup before flashing with phoenix suit and copy the whole "TWRP" folder from the internal memory to your microsd (or to your PC) if you don't wanna reinstall everything again. In this case restore the backup and after that flash the new zip. If you get any weird trouble do a full wipe.

you're churning them out at the moment Christian!

Have you got any initial impressions compared to your 4.2.2 stock repack? I know your repacks used to perform better than CM10, is it still the same?

Well, 4.1 AOSP based roms' main issue was the lagging keyboard that is not present anymore. It runs better than stock imho but not as smooth as an amlogic dual core running my AOSP roms, the same happened with the A10 that was running much worse than a less powerful RK2918... they're not that good imho

Hello Christian!

Can you please make a compatibility-zip for the V973 also?
Here is the Link for the original Firmware 3.0 for the V973 V1: V973 V1 Firmware 3.0 (Android 4.2.2)
This would be awesome. :)
tomorrow or tonight, I spent the morning setting up AOKP build environment, now I'm building it but I have to leave


@all

I noticed a bug, probably something upstream since it's not platform related, after a reboot the "multitasking" button (the app switcher) doesn't respond. As a workaround you can enable expanded desktop in the power menu settings, toggle it on/off and the button will work (you have to do it only once, after a boot for example). It looks like it doesn't get initialized at boot, I guess that future commits will fix it

Hi Christian!

I have the Freelander PD80-HD, it's my understanding that until Freelander release a Jellybean (3.0) SDK that you won't be able to make a compatability rom for it?
right because there are new video drivers and aw's kernel are too restrictive in loading modules not built against that particular kernel symbol table.

In this way is possible to add/make kernel modules for other CPU governor like pegasusq, zzmove, lulzactivq??

Work like stock, very smooth without any sort of lag;)

no, any governor apart fantasys and performance can't work with allwinner's SMP hotplugging. Not even linux's ondemand works properly

I don't work on kernels, I can compile them of course but it'd be useless since it wouldn't have any improvement.
