Return to Un-modded Stock:

Bootloader unlocked and TWRP and Root included

The file is 4gb compressed to 2gb. Depending on your connection it will probably take 20 to 45 minutes to download.

Be Advised

Do your research before flashing anything, I am not responsible for any damage caused to your device, due to impatience and missed steps. However, rest assured this recovery is solid and will absolutely return your X720 or X727 to stock 5.8.21s (with the bootloader already unlocked, TWRP installed and rooted)

I was asked by several people if I would be willing to share a link to my Stock X727 recovery, I created this thread to provide the 5.8.21s recovery for anyone who is experiencing dire issues or is simply wanting to restore the last official x727 recovery, as a daily driver or as a means to troubleshoot their issues by returning to the fully stock rom, stock partitions and ready to start over.

Attached is my full stock TWRP Recovery for my Le Eco Pro 3, version: 5.8.21s (X727)

It is a clean TWRP backup recovery that I did not mod in any way other than unlocking the bootloader.

The link is to my Google Drive account. https://drive.google.com/open?id=19dtLHmE5bsx5mdtEXOns4Z5drpeY79Em

Ensure that you perform a full wipe before applying this recovery, and that you know what you are doing before attempting to install.

Please note that any changes that you make to your device is done at your own risk.

Please use caution and make sure that you have TWRP recovery installed.

Be in the habit of booting back to recovery before booting to system....This is a good practice for ensuring TWRP stays installed

You must unpack the downloaded 7zip file, before it will be useable.

As long as you can boot into TWRP and have root access you will have the full permissions needed to install anything , and reverse any actions that do not workout as planned.

Personally, I make a backup of my existing installation prior to making any changes. I recommend that you do the same. If you buy an OTG adapter and a USB 3.0 drive it takes 5 minutes.

October 8, 2018:

I uploaded the Leeco Full Stock Rom 5.8.26s to my MegaDrive.

If you are selling your phone and want it to have stock without TWRP and without root , just flash this Rom and your stock radio driver "firmware" for your device
