All credits for this go to [MENTION=1900292]tora33[/MENTION], c/p from here, he tested it himself, and confirmed it working.

This should bring back your bricked phone from the dead, it's a low level flash procedure, meaning don't play around with it unless absolutely necessary, IT WILL WIPE YOUR PHONE CLEAN!

Charge your mobile phone

download :

New link for qfil file Qfil_zl1_ufs

and put in C:/

download : FlashOne2.0 , put in a folder and extract it ,

run "FlashOne2.0"

How to qfil Flash

When select qfil flash type, press power key, volume up and volume down key at the same time, then the phone enter into qfil mode, connect USB cable with PC, wait for PC install driver automatically, then press ‘Refresh’ button on the tool, serial port will display on UI, select the port you want to flash, and make sure there is no other qcom device connected.

Select corresponding flash zip file, the path of zip file should not contain Chinese and special character. (Under qfil mode, the tool can’t get hardware information, you should check if the software and hardware is matching yourself.)

Press ‘Flash’ button, then start to unzip flash zip file to current folder, but if there is already a corresponding unzip file existing, ‘Decompression folder is exist, re-decompress or not?’ dialog will pop up, if select yes, will re-decompress, else not. After unzip finished, start to flash the phone automatically, and the progress bar display flashing progress, and at the same time, the flashing log will also be shown on UI.

After flash complete or error happened, a notification dialog will pop up.

Hi,

I had the same error trying to revive my x727 while I was using a Qfil file provided by Tora33 on the w w w.leeco.re/topic/1906-helpx720-bricked

2017-06-11 02:18:18 QfilFlashThread >>> 02:18:17: ERROR: function: sahara_rx_data:194 Unable to read packet header. Only read 0 bytes.

2017-06-11 02:18:18 QfilFlashThread >>> 02:18:17: ERROR: function: sahara_main:854 Sahara protocol error

However, i finally succeeded with the qfil file from another link that was provided on page 2 of the leeco.re forum.

Just follow the same guidelines with the "newer" Qfil file.

One downside for me is that my x727 now thinks it is a dual sim x720 :)

[MENTION=1900292]tora33[/MENTION] --> Many many thanks for providing a working solution to revive our devices.

Thanks for this!
[LeEco Le Pro3 Guides, News, & Discussion] Efun:
Can confirm that this works. It took a lot of tries to work but it did. The things that I had to try before this actually worked include: hold the button combo to get into qfil mode for like 2 minutes, use the original charging cable, use a usb 2.0 port connected to the motherboard (e.g. use the back usb ports if you're using a desktop), holding the power button for a really long time, and charging for like 2-3 hours to make sure that the phone had enough battery. It is a finicky process, but it does work. The phone, if you were on a US rom, now reads as a 720 Chinese edition. That being said, I'm just glad the phone is back up and running lol.
[LeEco Le Pro3 Guides, News, & Discussion] bahuy2003:
I think, we can flash this rom by this tool. But, name of rom needs to be very short, example 1.zip.
[LeEco Le Pro3 Guides, News, & Discussion] alap1983:
Incidentally.. After the phone comes back to life... Your Le Pro 3 will be running a Developer Version of EUI. However, you can install the latest version of Official EUI version. Unfortunately, the method isn't simple and requires a bit more steps.

After the flashing is successful, your Le Pro 3 may not boot automatically. Press the Power Button for a LOOOONG time... about a a minute or so... for it to leave the QFIL Mode. After a long vibration, the phone will start and will take its sweet time to boot up. Have patience.

Incidentally... after flashing and first boot... you may notice that the Internal Storage is abnormally low... about 10GB Only. A simple solution to restore the internal storage to 32GB / 64GB is by going to Backup/Restore in Settings and Factory Resetting the Phone with the "Format Virtual SD Card" Option selected.

To install the latest Official EUI download the ROM from preferably official sources... Rename the file to Update (The file should read Update.zip... not Update.zip.zip) and Paste in the phone. Using the Inbuilt File Manager.... tap on the Update.zip file and choose upgrade. If this method works... Great...

If not... You will need to Flash TWRP Recovery, Wipe EVERYTHING... and flash the ROM using a Flash Drive and after mounting USB OTG Storage.

To Flash TWRP simply shut down the phone and By Keeping the Volume Down Button Pressed Hit the Power Button to Enter the Fastboot Mode.

Thereafter... flash TWRP Recovery... Boot into TWRP Recovery... Restart TWRP Recovery... Insert the USB Flash Drive Using USB OTG Adapter... and flash the ROM using the Install Tab in TWRP Recovery.

Thanks for ultimate guide, I bricked my phone trying to root it and this guide just helped me revived my dead phone. Thanks a bunch!

Just so everyone knows, when I phone was dead, it was just dead, I pressed the power button for several min, no response, completely black screen, while putting on charge, there was no light. So no sign of life at al.

Now it's revived and I have successfully rooted and installed AICP ROM.

Hello, I have exactly the same problem you had. How did you enter qfil mode when the smartphone was no longer responding. The software flashone me brand to re-connect me in flash mode. But the screen is still black. Thank you in advance.
[LeEco Le Pro3 Guides, News, & Discussion] kane35:
help!

Hello.

I have a leeco x722. I tested everything I could find but my smartphone is still in hard brick. No reaction, no sound, no vibration, no led, no screen.

It is still detected by the software flashone in QFIL. I have tested a lot of QFIL file but it still marks me "QFIL flash failed, please re-enter into the flash mode!" I try to stay pressed on the volume and power buttons and re-flash but still the same. Would you have a trick to switch to QFIL mode by being in hard brick. Or do you have a QFIL file for x722 and not x720.

Thank you.

QFIL X722

Hey! "Accidentally" Bricked my phone on pure stupidity. Is there any QFIL for the Le Pro 3 Elite X722 I need it so badly to have a chance to bring my phone back to life.

Tried your file but im getting this error:

[LeEco Le Pro3 Guides, News, & Discussion] DK Boneco:
Did you solve this problem? I made the same error with the X722 and am in exactly the same situation.

Qfil gives the same error. In an attempt, Qfil was able to download FireHose, but content.xml was in error. After that, I could no longer get Qfil down Firehose. And now this message always appears.

I already know that it is possible, just not how to get around this problem of Qfil.

Custom Roms

Hi, thank you for the guide as my leeco pro 3 (727) is successfully revived. I have installed twrp but whenever I try to flash any rom I always get error code 7 (device not compatible). Should I just delete the device checking part of the rom, or is there anything I missed. I have also erased the developer rom :crying: thinking that I had to do a full reset before installing a custom rom.

---------- Post added at 05:25 PM ---------- Previous post was at 05:19 PM ----------

What you should do is leave the phone charging. My phone after the flashing was completed still did not boot up, so I left it on charging and it booted up successfully.
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
You need to install the newest version of TWRP to resolve error 7 https://twrp.me/leeco/leecolepro3.html

First, if you do not click reply, the person you are talking to will not know that you asked another question. Second if you don't click thanks for their time, they may not give a care, much less spending time typing a response.

You need to get all of the files again , including the Qfil. You can unbrick the phone many times and have the files on hand. to do it again if needed.

On you last comment you were able to get into fastboot...So you cant go straight to TWRP, the steps are already on this forum I spent alot of time adding on to the pre-existing guide.

Below is an excerpt from my guide several pages back

FYI: You can not go about installing TWRP and Root until you have logged into the leeco OS

In EUI

* Make sure you have enabled the developer tools,

* Turned on USB debugging

* Authorized your computer on your device I.E: “MTP”

Install All in One Tool

Make sure the All in One Tool can see your device*

* Mauronofrio created a tool called: "TOOL ALL IN ONE"" it's great, install it and check for updates.

Get it here:*https://toolaio.tk**

* The all is one tool is excellent and you can use it to install everything if wanted.

* Highly recommended , you can it to help with unlocking the bootloader and installing TWRP, Rom, Gapps, and Root

* The tool will also update your copy of ADB, android Drivers and provide system wide privileges for ADB

Select your device from the drop down menu

Choose to install drivers, and set ADB and fastboot privileges from advanced menu.

First attempt to unlock, then check bootloader status

If you have a X727 you will need to flash : emmc_appsboot.mbn from this zip :*https://androidfilehost.com/?fid=313042859668275431**

Next, choose Recovery flasher and manually select your copy of TWRP ( if needed)

After you have received the success message, I recommend doing the rest of the install manually within Twrp Recovery.

Reboot into TWRP and begin installation of your Rom, Gapps and Magisk.

Is the charger safe to use if I have a different USB cable? Or should I just get new chargers as well? I have two leeco's and one already crashed. Trying to see if I can get a replacement usb port, but hopefully trying to prevent the other one from frying.

[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
I have no idea, I hope so. If Leshi ever want to rebuild the Leeco phone business ( as claimed) they should make releasing the Qfil for the X722 a high priority. It makes no sense that they have released their Open Source to us and we have Qfils for many devices, why don't we have it for the X722?

According to some posts on Chinese forums, people are testing a method that supposedly has worked on a couple of phones. If I can find that link again I will edit this post with the link. Personally, I find it hard to believe that they could do anything unless they have the signed Qfil.

If It ever becomes available, I will post a guide for unbricking.

---------- Post added at 10:09 PM ---------- Previous post was at 10:03 PM ----------

You are using the wrong firmware, use the one that I posted several pages back, it was about 2 months ago. Get the right Qfil and you should be able to unbrick. READ THE INSTRUCTIONS.

1) To enter Qualcomm Recovery mode

2) Keep pressed Vol Up (+) and Vol Down (-) together and connect the phone by USB cable to the computer.

3) You will see that the computer will install drivers for "Qualcomm HS-USB QDLoader 9008".

4) Unzip Flash 2.0 and start "main.exe". Once you've opened the flash-tool you'll see "Flash Type". Here select "Qualcomm - flash dead phone".

5) Select your phone - "COM ..." from "Select device" - here should be the same COM ... as it shown in Device Manager under Ports (COM & LPT) > "Qualcomm HS-USB QDLoader 9008 (COM ...)"

6) Select File the QFIL from the folder where it is saved

7) Press "Flash" in the lower part of the window

8) Once completed, disconnect the phone and power it up

9) Go to Settings – Storage format the internal storage.

To exit the Qualcomm Recovery mode, keep the Power Button pressed for about 1 minute or until the phone will vibrate and restart into system.
[LeEco Le Pro3 Guides, News, & Discussion] Jayce Jocelyn:
I just tried again with your provided Qfil file and it failed again (The one Google Drive link). Is there a newer or other file I could try? And I don't get why it isn't working. Device is properly shown as COM6, I used your file and flash dead phone. It starts and then fails at 1% with this:

"13: C:\Users\random\Downloads\FlashOne2.0\3\prog_ufs_firehose_8996_ddr.elf

[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
Lets be clear you do have a Leeco X720 or Leeco X727 right?

If so

This is a problem caused by your computer, follow the computer preparation steps, specifically the Qualcomm drivers., removing peripherals, using the back of the desktop usb, temporarily disable anti virus and firewall. Firewall alone can cause a Sahara error. but its probably the driver.

This is the best way to unbrick

There is also the QPST method.

Edit : A couple of additional thoughts:

Remove QFIL and Qualcomm drivers

Clean your registry, there is a manual way. But its much easier install the trail copy of CC Cleaner

After cleaning, reboot the computer and reinstall the files.

Also if you continue having issues, buy this cable : https://www.amazon.com/Flash-Cable-..._rd_t=40701&psc=1&refRID=HAA21WN0KMHN3K2NM5K2

Here is a cheaper one: https://www.amazon.com/Flameer-Xiao...07275&sr=1-1-catcorr&keywords=EDL+Cable+usb+c
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
Go back and read through this forum, this issue has been answered. You are either using the wrong Qfil ( most likely) or your firewall is blocking the download.

I have done the entire process of installing Qfil with FlashOne2.0 software, everything happens correctly, however my X720 does not start the ROM, it vibrates twice and it restarts again. Is the problem hardware? Can someone help me? I'm Brazilian and I'm using google translator.
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
From my post within this thread :

After completing the flash press and hold the power-button down for 30+ seconds and the phone will vibrate

* Release the power-button, it will vibrate again after 10-20 seconds*

After you have performed all of the steps*

* Your Le Pro 3 will have the temporary repair version of EUI.*

* The phone may not boot automatically.*

* Press and hold the Power Button for two minutes or longer.*

* iIt will leave the QFIL Mode, and will vibrate continuously for 20 seconds or longer.

* The phone could take as long as 15 minutes to start.

* Immediately you will notice that part of your storage is missing.*

[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
The Sahara fail is an issue created by your computer. Uninstall the android USB driver and reinstall. Better yet uninstall the driver, flash 2.0 use a registry cleaner such as CC cleaner, clean registry then reboot. After reboot reinstall and try again.

Don't forget to use a port on the back of the computer and disconnect any unneeded peripherals such as external Hard drives etc.

Edit, that is weird about the link, I checked before I sent it and it was working then?. My notes are at home, I have other links I can send you when I get back home.

There is an alternate way to unbrick your phone using QPST Software : https://easy-firmware.com/index.php?a=downloads&b=folder&id=8158

You still use the fixed Qfil version but with the QPST program instead.

[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
Yes, you will just follow my instructions here: https://xdaforums.com/showpost.php?p=75009966

On second thought, he Qfil is a developer Rom. After restored, just use the traditional way to unlock it via Developer settings within the Rom.

Finally, After you have done that you will have a storage issue, so flash X720 firmware, go through setup , unlock bootloader ( again traditional way) then flash whatever you want.

Or you can flash my Recovery : https://xdaforums.com/showpost.php?p=75021582
