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

* This ROM may be a bit more unstable since it's built with more aggressive CFLAGS and a different compiler
* 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.
* This is not a broken functionality but a lack of this ROM that can only export one partition through USB Mass Storage, if you wanna access to both memories you should use MTP instead of UMS, only CyanogenMod can export multiple LUNs.
* 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 (pa_spark-$VERSION-$DATE.zip) and gapps (gapps-jb-$DATE-signed.zip) files inside internal or external sdcard.
* Turn on the tablet in recovery mode as explained in TWRP thread.
* If this is your first install select "Factory reset" from "Wipe" menu.
* Flash rom (pa_spark-$VERSION-$DATE.zip), gapps (gapps-jb-$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

* Some changes under the hood: who is using a USB nic try to see if it brings it up automatically and who uses a 3G dongle try it again and if it still fails post a logcat
* Updated upstream sources

"MDPI" devices (those not having a "retina" display) have to flash this zip as well. Since "MDPI" devices are not officially supported from PA team some things might not work properly.

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.

No, spark only. It's a kernel issue.

By the way, this is the best custom ROM, even for phones. Everyone should check it out. Such features - even the real manufacturers can't stand against them.

Is there a way to go to the recovery after flashing this rom ?
I don't find the recovery in the settings. And I don't know if it's possible to go to recovery with some button when the tablet starts.

I found this rom interesting for customisation.
But I found it a little slower than repacks. And some bugs are the same than stock/repacks (google drive gives full white document when editing an existing doc for example).

Thanks for all your roms christian, you really give second life to this tablet.

But I'm afraid how such a heavy ROM might perform on our poor sparks.

By the way which version is that? 3+ is fine, but that's a bit too common phrase. Which exact version is that?
Probably no HALO, but I don't see any need for it on a tablet.

But still, good work.

If you look at the last screenshot you'll see Halo, useless anyway if you use the tablet UI because can't be triggered.
When I release a ROM it's always synced with the upstream repos at the time of the rom build date

Can you try to flash this zip and tell me if you notice any improvement in stock browser web pages rendering? It looks better to me but I don't wanna be fooled by placebo effect


This is for PA only, if you wanna try it on CM10.1 or AOKP 4.2 take a nandroid backup because it may refuse to boot (or save a copy of the previous libwebcore.so)

Try it because if it works I'll include that change in next ROM updates (all 3 of them)
