Downloads
  • Download tab above the thread
  • If you use an unmodified stock KK or LP rom, stock recovery will be self installing again unless you flash KK_LP_no_stock_recovery.zip patch.
    In TWRP, you need to be sure that "Mount system partition read-only" is unchecked in "Mount" menu before flashing this patch
Installation instructions

3 ways to install this recovery
  • Using SP Flash Tool

    Prerequisites
    In SP Flash Tool, always use "Download Only" mode when not explicitly asked to do otherwise (you could lose your IMEI/WIFI/BT) or if you don't know what you are doing.

    Please do NOT ask about any problem with USB drivers or SP Flash Tool here in this thread, this is not the right place for it as these problems are not related to THIS particular recovery but to YOUR computer setup.
    There are other threads and/or sites about such problems.

    Installation
    • power off the tablet
    • launch SP Flash Tool, click on "Download" tab
    • click "scatter-loading" button and choose the downloaded scatter file (MT8127_Android_scatter-recovery_only.txt from Download Tabs is based on LP stock rom)
    • on the "RECOVERY" line, click the empty "Location", and choose the downloaded recovery img file
    • click "Download"
    • plug your tablet on USB
  • Using previous already installed TWRP
    • reboot to recovery
    • "Install"
    • "Install Image"
    • choose the recovery img to flash
    • choose "Recovery" partition
    • "swipe to confirm Flash"
  • Using an application (root needed)
    such as Rashr
Boot to recovery
  1. Turn your tablet off
  2. Push Power button + Volume- + Volume+ buttons
  3. Keep the buttons pushed untils boot logo appears

Now time for new rom , i think you should try out building any cm based rom , omni is 75% Aosp so there might be some issues.

How can AOSP be an issue ? I always choose opensource when possible.

For mediatek open sources are not totally compatible with aosp's . every mtk chipset has same issue. So you can try out other others.

Yep,agreed.With the years cyanogenmod went on its own and its not really based on aosp right now,while omni is more aosp based rom.

A few month ago, with a friend we did this for omnirom, we got boot (prebuilt kernel), graphics, but no wifi etc... : https://github.com/PixNDom/android_d...novo_Tab2A710F https://github.com/PixNDom/android_v...novo_Tab2A710F (other repos https://github.com/PixNDom).
We stopped as we did not know how to go on.

Yesterday after your advice i started a cm12.1 branch on my github (https://github.com/pix106/android_de...0F/blob/cm12.1), and got TWRP running using cm12.1 sources (with wrong device id, but it does not matter now).

I tried building the kernel again using lenovo sources (https://github.com/pix106/android_ke...ovo_osc_201511), with cm12, i got the same result than i got with omnirom : no graphics, "GTP Reset", i2C errors...

Thanks for your help
