CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.1 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.

Code:
#include 
/*
 * Your warranty is now void.
 *
 * 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
 * before flashing it! YOU are choosing to make these modifications, and if
 * 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 CM12 or a previous build of CM12.1, just make Wipe Cache & Wipe Dalvick-Cache for a proper upgrade.
  3. Install the ROM using Recovery
  4. Install the adapated Google Apps (Latest Paranoid Gapps for 5.1)
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 !
  • 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. (should be fixed)
    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
  • GPU HWComposer & HDMI, please check this post

I flashed my pad to 5.1. It suddenly reboot in first hour. I keep it in suspend status for a whole night then I reboot manually. After rebooting, it runs system optimizing process again. What's wrong with the dalvik cache partition? But it seems the system is very statble and smooth now.

Struggling here to install the gapps, as "insufficient space" - error 70. Moved from CWM to TWRP but still not luck with stock and full. Without the gapps, CM 12.1 looks fine though.

LATER EDIT: mini flashed successfully. So my \system is too small, huh?

Yes, /system partition is very small on A510, CM12.1 is possible thanks to LVM.

Hello Shreps,

What I'm doing wrong?

Thks for the rom.

I thought i had the same problem while flashing: twrp seemed to freeze, but after a about 15 minutes the rom was flashed (along with PA Gapps Pico).

First impressions: the initial setup (WLAN, google account) was extremly laggy and after each step the tablet rebooted.
After enabling Developer mode the A700 crashed and rebooted but they were enabled afterwards.
Unfortunatly a message that the storage space is running out popped up.
Next reboot after enabling expanded desktop.
WLAN, expanded desktop and camera work, bluetooth and GPS couldn't be tested at the moment.

This was the second lollipop build I have tested on the A700 and like on the other build the screen turns completly black on minimal brightness - I hope this helps.

I will test it now for a while before reverting to PacRom RC3.

Un grand merci à Shreps for his awesome work kepping the A700 alive!

test on A700

Thanks Shreps, I´ve tried to test your rom on my A700. Flashed it with TWRP 2.7.1.0 and after reboot, I got the brightness problem and cant fix it.
Can´t connect through ADB cause of "device unauthorized". And I can´t accept incomming connection on screen, cause i cant see the dialog. :(

I´ve tried to enable adb via the shell in TWRP but it didn´t work at all.
Code:
echo "persist.service.adb.enable=1" >> default.prop 
echo "persist.service.debuggable=1" >> default.prop
echo "persist.sys.usb.config=mtp,adb" >> default.prop
echo "persist.service.adb.enable=1" >> /system/build.prop 
echo "persist.service.debuggable=1" >> /system/build.prop
echo "persist.sys.usb.config=mtp,adb" >> /system/build.prop


If you can fix it, i will like to test your roms. :good:

After a long install I have the same problem that Flippo24 got.

If you find where could be the problem, I'd like to test your rom too.

    For me the new version is much better than the previous one. You should release new builds more frequently, I guess ;) @Shreps

    I will :p
    But there are less and less A510 users, so those build are only for you guys.
    Even I no longer use the tablet, only to flash builds and make some testing, that's all.

    A new build is online based on the r6 tag ;)

    On this build I upgraded hwcomposer vendor blob using the grouper one (Android 5.1)
    It might improve graphics rendering.

    I will now also try to play with z-kernel and try to bring up it to lollipop in a clean way.
