CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.

Code:
#include 
/*

 *
 * I am not responsible for bricked devices, dead SD cards,
 * thermonuclear war, or you getting fired because the alarm app failed. Please
 * do some research if you have any concerns about features included in this ROM

 * you point the finger at me for messing up your device, I will laugh at you.

CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit out Gerrit Code Review.

These unofficial builds are based on the CM t30 Kernel available at https://github.com/CyanogenMod/android_kernel_acer_t30

All my specific device tree can be integrated in the CyanogenMod project.

Requirement
  1. An unlocked Bootloader - JB Version
  2. CWM recovery or TWRP recovery
    version 6.0.5.0+ with LVM Support (Look at the CWM thread) or TWRP with LVM Support (called bigsystem by Elibl)

Installation
  1. Do a Nandroid Backup!
  2. Wipe data/factory reset if coming from another ROM or version of CM. If you are already on CM11 or CM12, just make Wipe Cache & Wipe Dalvick-Cache for a proper upgrade.
  3. Install the ROM using Recovery
  4. Install the adapated Google Apps (I recommend minimal Gapps 5 on my website gapps-lp-20141109-signed.zip but you can use Latest Paranoid Gapps for 5.0.x
Note: The partition layout of CM12 is identical to that of CM11 with LVM and thus you may use CWM with LVM to backup/restore.

Bugs & FAQ
Known Issues:
  • RIL not compatible with A511 :(
  • Flashing L might take a while in recovery (please be patient)
  • First boot might take a while too !
  • Frequent random crashes
  • Bootanimation crashes after a while (but the boot process continues normally)
  • Setting brightness to minimum while on auto brightness may cause the screen to go completely dark with no way to set it back except for guessing where the brightness setting is or using adb to force set a higher brightness.
    If you have a black screen at first boot or after bad settings manipulation, use this commande in adb :
    Code:
    adb shell "echo 255 > /sys/devices/platform/pwm-backlight/backlight/pwm-backlight/brightness"
    If it doesn't work, push power to enable your screen and try the command again.
    If the bug comes with auto-brightness enabled, you can put your sensor on a light to force it to level up the brightness.
  • SELinux not in enforcing mode
  • Bluetooth may not work properly

I'm not sure, the t30 kernel is very Acer specific on many driver part.
We need a good Kernel dev to manage to make it "clean" and remove all the Acer specific code, that would be great in order to properly upgrade the Kernel next.
Actually, we're stuck on 3.1 Kernel version because of these Acer code.

But I'm not this person, I'm lacking kernel skills (and also free time) to do this.

Unfortunately we had only one kernel dev.
But we lost him, because he has no tab anymore.


CM12 ist running on my A510 since 0:45 (in germany) without any problems, except brightness minimum.

I wiped system, cache, dalvik and internal memory (to delete all data from older installations)
Than I flashed CM12 and Gapps with TWRP.

I didn't tested Bluetooth.

kernel work is really a pain, i agree.
It requires a lot of time to get something working..

CM12 isn't rooted?

It's no problem, I flashed SuperSU 2.45 to get root.

I have a bug in gallery app

https://docs.google.com/file/d/0B_Ls_Pd3r1HIR0s0UlhGUlpUbE0/edit?usp=docslist_api

There are grey fields between my pictures.
All real existing pictures are shown, but between them are this grey fields.

Cyanogen Gallery shows all pictures correct.

When I try to use G+ Foto App, Android media server crashes.
Gallery and Photos G+ app working fine on My tab.
Try to clear cache and remove thumbnail dir on your memory

Didn't work for me.
This grey fields are no missing pictures or missing thumbnails.
All real existing pictures have thumbnails.

It's OK for build in gallery but FC happens in Google Photo.
I have wiped both cache and delete cache.
After upgrade process finished, I can't go into desktop. So I wiped data as well.
Finally I read install instructions again and figure out that the problem is caused by backlight setting.
Then I install gaaps again.

About the Gallery app issue, @HornetRider I think you should try to format your internal memory an push back cleaned photos

About the Photos issue from G+, it could be a gapps issue, you can try to flash another gapps package. On my tab, I upgrade Google+ from the play store, and no problem using the Photos app.

First thanks to Shreps for his great work.

For myself I found a solution of this Brightness-Gate.

I played a little bit in the configuration settings.
and then I turned off a funtion, called "Adaptive Brightness".
Look at my picture.

Since then, I have no more issues with calibrating brightness

I suspect the missing thumbnails caused by the scan media process.
Coz I can't run build in Music app as well but I have a solution.
I tried to eject SD card and rebooted my tablet.
While system is running in second boot, insert the SD card again.
Now I ve got most of the thumbnails but still some missing.
Moreover, I can run Google photo now but it shows many missing media icons.
Music app now is running in perfect status. It show all songs and covers.
No more force closed happen.
I'll try to backup all data in SD card and format it.

Hi,
First of great work Shreps and thank you for continued support.

i have a problem. Made the install (full wipe cache, dalvik, data) after install and first reboot the black screen (tried several clean installs with and without apps). problem is that i cant make connection with ADB to send command. The computer (windows 8.1) recognizes the tablet connection when connecting usb, but adb can't find the device.
any solution for that?

I use twrp recovery and in the recovery mode adb is finding my phone.
i'm kind a noob here

Fixed: use windows 7 for debugging

I wiped the internal storage together with system, cache and dalvik , before I flashed CM12.

But all my photo folders are on my external SD-Card. Maybe I should wipe the card (after backup all important data)?





I'll try to backup all data in SD card and format it.

Did this solve your problem?
Than I'll try it also.

    Wonderful @Shreps, and thank you for all the great work provided, thanks to you, our dear iconia continue to survive until 2015 ^^
    unfortunately this rom does not work for me :/ , after several failures, I think the cause is my bootloader which is always an ICS version, btw if a charitable person could point me to a link or a way to upgrade/update my bootloader to JB version, I would be eternally grateful ;)

    Regards

    The simplier way is to go back to stock and flash the Acer JB official Firmware. Then you will be able to flash back custom ROM.

    @Shreps I'm currently using your CM11 rom and I probably will wait with upgrading to Android 5 until there is a more stable version. But I already want to say thank you for all your effort. As already mentioned, it's great to see that a tab from 2012 still gets supported by the community :)

    As HornetRider said, it's quite usable.
    I will change the thread status to "beta" ;)

    I will consider it as stable when A511 (modem/ril bug) and Brightness bug will be solved (if I can...)

    Please take a look at this commit: https://github.com/zombi-x-lp/android_device_acer_t30-common/commit/a86e7595ad850c51983279bc10683abb81f9650b

    This seems to fix the screen going black with auto-brightness in a dark room :)

    Yes, I laready had those kind of config to try, but didn't had time for now.
    Will test this when I can :)
