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 <std_disclaimer.h>

/*
 * Your warranty is now void.
 *
 * We are 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 us for messing up your device, we 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. You will need to provide your own Google Applications package (gapps). 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 our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

  • kernel bug fixed : after a suspend, CPU freq was limited
  • first boot is way faster

Changelog

Downloads

Installation
  1. Download the ROM (and optional Gapps) zip, and put it on the internal or internal sdcard of your tablet
  2. Boot TWRP recovery
  3. Perform a nandroid backup of your current ROM (optional but recommended)
  4. Wipe Data/Factory reset
  5. Flash ROM
  6. Optional: Install the Google Apps addon package
  7. Reboot
KitKat users :
If you're coming from a KitKat ROM, you need to install a minimal stock LolliPop upgrade before flashing CyanogenMod.
Get the package from Downloads tab and flash it using SP Flash Tool.
It includes TWRP 3.0.2.0, so you can flash TWRP3 and the minimal upgrade at the same time.
​

Update
If not explicitly asked to do a clean install, you can update a previous version without wiping your data
  1. Download the updated ROM
  2. Boot TWRP recovery
  3. Perform a nandroid backup of your current ROM (optional but recommended)
  4. Flash ROM
  5. Wipe Cache/Dalvik cache
  6. Reboot

Which gapps are you installing , I never found any issue with gapps. Maybe you didn't wipe data, cache and system.

Just go to wipe > advance wipe and wipe system,cache,data,dalvik cache then flash.

Thanks, but I do not put the firmware for the first time;)

The point is clearly not in the GAPPS

Don't install the package you downloaded yesterday, it has a problem and was removed.
Delete it, [email protected] will upload the good version later today.

The TWRP error message, and the install instructions on the first post seem pretty clean to me : you need to "factory reset"=wipe all data first

Our device doesn't have a real device section, like flagship devices do.
We have a "tag" : http://forum.xda-developers.com/t/lenovo-a710

Dev threads cannot be created directlyinto a tag, i asked a moderator to move it under the tag seconds after creating the thread.
So it will be moved eventually.
