All ROMs for the LePro 3 do not have the Harman audio, because the LePro 3 does not have the audio developed by Harman Kardon. But I can assure you that you feel good too.

The C105-E0 is for all Cool Changer S1, i already tried the JUI but I do not like it.

Hi, price is very low now in China for China Mobile version with NFC. I am thinking buying one for my wife. What you be the best stable rom so far? she is used to Miui as she is using a Xiaomi Note. Will NFC work with different roms?
Many thanks for your work!

Hi, in theory it should work with other ROM but I assure you nothing, the ROM I'm using right now is the Pixel Experience 8.1.0 , it really goes very well with the 2.15GHz kernel. 175000 points on Antutu and great battery life.

Thanks for your quick answer, I will check on Chinese forum or 4pda if it is working or not (not big deal anyway). Could you add the link to Pixel rom in the first page? Thank you very much.

Ok, tutorial worked for me. I have quickly tested Omnirom. Coming from Miui it is hard to go for Android "stock" roms. NFC not working properly though. I will try other roms.

Yes I think I will go for AICP 13.1 unless I can find a good Miui rom. I have tried one from Chinese forum but it is really laggy (I suspect bloatware, I need to root it to get rid of them). Too bad because everything seems to work well. I will try another one (Miui 8 on Android 6). If results are not good, I go for AICP.

I have a problem after having flashed AICP 13.1. Wifi can connect but says "Connected, no internet access". I think I had the same problem on Omnirom but was able to use Wifi. Here it has been working for a few seconds, now doesn't work.
Edit: same problem with sim card. LTE is enabled but cannot access network. By the way I am in China, could it be the problem? (I have seen it could be a problem with Google).

The same problem was occuring in several roms, even on Flyme OS. I have flashed again the LePro3 switch rom and flashed Miui 9 V10 by venezolano69. Everything works fine so far, and NFC is working too. The rom is good (maybe not as smooth as AICP but at least I have internet and NFC working!).

Nice, good to know, but what model do you have? C105-6 or the C105-8?

    ATTENTION: I take no responsibility for any problems you may have. The guide was tested on variant 6/64 (C105-6)

    I created this guide especially for the English translation, but also to be as clear as possible. I hope you enjoy it.

    Ok lets start!

    NOTE: find all the files at the bottom of the thread. Once the conversion is done, you can install any ROM for the LEX720. Under the thread I wrote some ROMs.

    STEP 1: Flash TWRP Recovery and Unlock Bootloader (if you have already unlocked the bootloader and installed the twrp recovery skip this step)
    1) First go to settings on your device, go to info and press 5 times Build Number to unlock the developer settings
    2) Go to Developer settings and active OEM Unlock and USB Debug
    3) Now Download the zip TWRP file and unpack it
    4) Open CMD from unpacked folder and connect the device on your computer, write this command on your cmd windows and press enter
    Code: 
    adb devices
    press on always allow usb debugging and press ok
    5) Now reboot your device into Fastboot Mode (power button + volume key down)
    6) Connect the device on your computer
    7) Go to unpacked folder and open cmd
    8) Now in order write these commands
    Code: 
    fastboot oem unlock-go

    Code: 
    fastboot flash recovery recovery.img

    Code: 
    fastboot boot recovery.img


    Well done, now you have TWRP recovery!

    To change the language press on right button and select your language, after go to reboot and press system

    STEP 2: Conversion from Cool Changer S1 to LePro 3
    1) Reboot your device on Recovery Mode (TWRP) (power button + volume key up)
    2) Make a backup of everything including EFS (Optional, just for security, I have not lost the IMEI codes but I still suggest doing this step. And save the Backup folder on your computer, the il folder is called TWRP)
    3) Do a Factory Reset go to Wipe and make Format Data, write yes to confirm, after go again to Wipe, Advanced Wipe and do: Dalvik, System, Data and Cache
    4) Now connect the device on your computer (from recovery)
    5) Donwload the Conversion ROM and put it on your device go to Install and Flash it, after your device will reboot but the system will not start, you will only see the boot logo and a black screen. Do not panic, restart the device in recovery.

    STEP 3: Flash Custom ROM
    1) Connect your device on your PC from Recovery
    2) Before installing a Custom ROM I suggest to update the TWRP recovery because the ROMs like the Lineage OS can not be installed because the installation package does not recognize our device as LEX720, then download the updated IMG file of the TWRP recovery and copy it into the device (always from recovery), go to install > install image and select the IMG file of the TWRP recovery, after go on Reboot and press on Recovery.
    3) Download on your PC a ROM you want to install and put it on your device (i have choose Lineage OS)
    4) Download on your PC Gapps from OpenGapps Website and put it on your device (download only ARM64, and i suggest the pico package)
    5) Now on your recovery go to Wipe and make Format Data, write yes to confirm, after go again to Wipe, Advanced Wipe and do: Dalvik, System, Data and Cache
    6) Now go on Advanced > Config Device> Set_Device_zl1, go back, go to Install and choose the ROM that you have downloaded, do the same thing (without set the device to ZL1) for Gapps without do any wipe.
    7) Reboot your device and now you have a Custom ROM!

    STEP 4 (optional): CPU to 2.15 GHz or 2.35Ghz (Only for Lineage OS Based ROMs and for JUI ROM)
    1) Reboot your device on Recovery Mode (TWRP) (power button + volume key up)
    2) Make a backup (Optional)
    3) Go to install and flash 2.15 GHz or 2.35 GHz (i suggest the 2.15GHz because the 2.35 version is not stable and can cause problems, for Oreo there is only the 2.15Ghz version)
    4) Reboot your device, you are done!

    ROM I'm using right now: Aosp Extended 5.4 Android Oreo 8.1 with 2.15GHZ kernel, the build I'm using is April 9th, because the 2.15GHz kernel with the latest builds based on the latest Codeworx sources causes data encryption so do not use the kernel until the developer releases an updated kernel!

    Not a Coolpad owner, but just here to comment and give my support. Great job! I wonder why LeEco releases so many phones with literally the same specs. Like... there's barely any difference between this phone and the x720 yet they're sold as separate devices. LeEco has some weird business practices.

    Yep if you want, i can make a video but the steps are really simple.

    To return to the EUI follow these steps.

    First, you have to go back to the EUI, to do this you have to install this from recovery (do wipe data, cache, dalvik and system): https://yadi.sk/d/F1cwov7_3HoFAa

    Reboot and wait for the device to start the system.

    After, Reboot into recovery you have to install another rom, this (now you can do Format Data and do wipe data, cache, dalvik and system): https://mega.nz/#!YVdDHQTT!pCOA8P0eCoy9bPhiqrBdNF1Dg5tjL3CB_DV6ImlSBVI

    Reboot and now you have EUI.

    now you can follow my tutorial, if you already have the TWRP skip the first step.
