Android-Version: LineageOS 14.1 R36
Build-Version: Build 20210307

How to install the ROM

You have to use my Unoffical TWRP 3.5.1_9-0 (3.18.19) Recovery to flash your device later. The file in the attachment is zipped and valid for the TWRP Recovery (don't extract the rom zip!). Please backup NVRAM and IMEI with TWRP BEFORE flash! If you lose your MAC / IMEI after flash, you can restore it in 2 seconds!

First time installing the ROM
Boot into TWRP -> delete Dalvik, Cache, System and Data -> Install the ROM ZIP -> Install GAPPS  -> Restart your phone -> thats it!

Upgrade from earlier version
Boot into TWRP -> delete Dalvik, Cache, System -> Install the ROM ZIP -> Install GAPPS  -> Restart your phone -> thats it!

Update to newer version with patch
Boot into TWRP -> Install Patch ZIP -> delete Dalvik, Cache->  Restart your phone -> thats it!

Bugs and how you can fix it

- to reduce flickering on apps (only few have this issue), go to: settings -> developer options -> animation duration scale -> animation off

- Video recording inverted color (workarround: any third party camera)


Whats works?
- everything

what doesn't work?
- some media codec are not supported (Youtube, Twitch, Camera, etc works)

Is the ROM rooted? 
No. You can install Magisk or SuperSu with TWRP

What about other languages?
You can choose your language as usual after first boot with the asisstent

Are the Google Play Service already installed in this ROM?
No. You have to install newest open pico gapps (ARM -> Android 7.1 -> Pico)

We'll get soon MIUI, IOS or Samsung TouchWiz as ROM?
No, No and No. All three ROMs exits but they are so buggy.
I dont will publish these ROMs. They are not ready as daily driver.

How to fix app store signature spoofing in MicroG settings?
You need to write this in adb shell or directly in device terminal :
pm grant com.android.vending android.permission.FAKE_PACKAGE_SIGNATURE

What is the different between source and optimized in changelog version?
source: build the custom rom directly new from source code
optimized: only changed some files / fixed bugs from latest rom

    Kernel: 3.18.35 Support???

    Stuck BOOTLOOP

    • seluce



      I build ROMs for Cubot Note S and Cubot Rainbow. So i can use the 3.18.19 Kernel from Echo to build similar ROMs from source.
      This LineageOS14.1 based on Kernel 3.18.19 which is based on Android 6.0. You need the TWRP 3.2.3-0 based on 3.18.19 and flash then this LineageOS14.1

      You only take TWRP 3.18.35 for offical V19 (Android 7.1.2).
      it does not work (bootloop) if you take twrp for nougat and flash custom rom based on marshmallow

      So the correct steps:
      Step 1: Download V15 offical ROM
      Step 2: Flash V15 with SPFlash Tool and boot it once
      Step 3: Flash TWRP 3.2.3-0 based on 3.18.19
      Step 4: Go into TWRP Recovery
      Step 5: Wipe "Dalvik, Cache, System and Data"
      Step 6: install LineageOS14.1
      Step 7: install OpenGapps (ARM -> Android 7.1.2 -> Pico)
      Step 8: Restart into system normally

    the first to forgive for the translation, the second …. thank you very much for giving more life to the cubot echo and for the work put in the firmwares ….
    my doubt:
    I have installed in my echo:
    -TWRP 3.0.2 Jemmini of this page
    -ROM Android 7.0 official also of the page
    with kernel version 3.18.35

    which TWRP do I need ??? twrp 3.18.19 and do what you indicate or install twrp 3.18.35 with flashtool

    I feel my writing, even though we have google translate jijiji
    a big greeting from Spain thousand thanks

      You need to flash Offical V15 (3.18.19) and then go for TWRP 3.2.3-0 for 3.18.19 which is linked on the description on top

      I dont support CUBOT Echo with 3.18.35. All my roms are for 3.18.19

    a small question……
    SuperSU install it after gapps?
    or can I install it after I have turned on and used the phone?

  5. seluce



    Go first for Rom and GAPPs
    Boot it up once and then go into twrp again

    You can choose between SuperSU or Magisk. Both are for root. I would prefer Magisk, its newer and have also Magisk Hide (hide su rights for some apps, banking apps for example)

      thank you, everything has gone perfect ..
      in the election I prefer supersu k I know it more
