Here is a link for a fastboot Rom : https://www.forumandroid.com/konu/6...gs-23s-rom-for-leeco-le-pro-3-x720-x727.8900/

Once you are able to boot to fastboot, you can use this rom to restore the phone to stock by using the Fastboot.bat file.

Basically all you do is unpack the rom run the fastboot batch file and it will restore the phone 1 file at a time. Once complete your phone will be like new, all partitions repaired complete with the installation of the EUi 23s stock Rom and EUI Stock Recovery.

I have used this file on several occasions, for bricked phones that were mailed to me for repair.
[LeEco Le Pro3 Guides, News, & Discussion] dark_prince:
You have, like all of us, corrupted flash memory of the phone. There is no way to recover. You'll end up in Write Fail errors in QFIL/QPST whenever you try to flash the factory rom via 9008 mode. This phone is made from cheap and unreliable manufacturing process which is making it disposable device.
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
Not Necessarily, his link was for a unbricking tool. The issue that he is describing is very often a driver issue > related to the PC. Out of the last 9 bricked Leeco's phones that were mailed to me for repair : 5 were repaired and shipped back in working order. The remaining four were either issues with the memory as you suggested or burned chips. There have been many more cases of successful unbricking handled in the three unbricking threads and by Private message discussions.

The most recent spate of issues were caused by msm thermal not working in earlier builds of pie. The issue was resolved, so new versions of Pie are much safer than the versions of Pie for Leeco Pro 3 that were available in mid to late November.

I am not doubting, that the remaining unresolved phones have hardware issues such as what you described, I just do not like to give up without exploring every possible resolution before quitting and saying its due to cheap parts.

For the record, Leeco used A grade parts ( Low test failure ) up to where they began having financial issues and could not purchase through regular vendor channels. Chiefly : Haosheng Electronic Technology who shut off their parts supply in November 2016.

This resulted in reverting to buying B grade parts ( High Failure) from alternative suppliers. Leeco continued making phones, and those post early 2017 manufactured phones made after this date indeed are more likely to fail.
[LeEco Le Pro3 Guides, News, & Discussion] lokster:
So, my X720 got kinda bricked. I was running one of the recent nigltlies of lineage os 15.1 (I've been running lineage os for a long time).

The past 1-2 weeks I had a couple of spontaneous poweroffs - I leave the phone on, only to find it completely powered off. But I was able to power it on afterwards.

The last time however, I left it charging, and found it powered off. When powered on, it was having infinite boot loop - it shows the LeEco logo, and after 30 seconds or so - reboots and starts over.

Booting to recovery - does not work. It shows the LeEco logo and the "RECOVERY" text, and after 30 seconds or so - reboots.

Only fastboot mode works. I am able to execute all fastboot commands without error . For example, flashing TWRP works as if everything is OK, but when I try to boot it with "fastboot boot blahblah.img" (or reboot the phone and try to enter the recovery) - nothing happens, and the phone just restarts after 30 seconds, and enters the infinite boot loop again.

I tried both FlashOne2.0 and QPST methods - same. Many times. They both work without any error, but then nothing happens - I am still unable to boot anything except fastboot.

The battery is charged & is charging (I checked with fastboot.exe getvar battery-voltage).

Any additional ideas? Looks like the phone's really unrecoverable...

Hello, my English is bad so I'm using google translator hehe. I have followed all the steps of this solution (for x720) and I am stuck on the following error:

Try this method: https://xdaforums.com/showpost.php?p=77723528&postcount=2

If that doesn't work go to post #2 and #3 on this thread. Re read the OP. Most of the time when people have issues and can't unbrick they missed a step. Take a deep breath and start over.
[LeEco Le Pro3 Guides, News, & Discussion] T1an:
I have the exact same situation as you. I've already lost all hopes :(
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
I never saw and was never notified of that guys issue.

Unfortunately if you have the exact same issue that he has:

You try the steps of using Flash 2.0 and Qpst and the Qfil is flashed successfully.

After success the phone constantly reboots in Recovery or booting to system.

All of this means you have a fried CPU.

Its not the battery, your CPU/GPU is definitely burned and unfixable.

Sorry for the bad news, don't waste any money or time trying to fix it. Motherboards are $150. You can sometimes find a complete X720 for that and sometimes brand new for $150

Well here is one for $140 : https://www.ebay.com/itm/LeEco-Le-P...915262&hash=item3fb5aa8a53:g:Tq8AAOSwzd9cJ0jP

LeEco Pro3 X720

Happy New Year to all!

I have a problem with my phone LeEco Pro3 X720.

It was already rooted only and I was trying to put the lineage 15.1 rom without success.

The result was to stuck my phone at the LeEco page which is written below "Powered by Android" without booting to system.

I cannot turn it off, I cannot proceed to twrp recovery mode or to fastboot mode.

Can you give any advise please.

Rgds.

Dimitris
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
You did something wrong?

The best thing to do is to start over. Put the phone into fastboot mode to decrypt and wipe it. Then reflash the current version of TWRP, your Rom of choice, Gapps, Magisk 18 using adb and then an OTG Drive

If you have troubles, use the All in one tool.

The all is one tool is excellent and you can use it to install everything you want.

You can use it to unlock the bootloader.

Remove Encryption

Install TWRP

Install your Rom, Gapps and Magisk etc.

The tool will also update your existing installation of ADB, Android Drivers, and provide system wide ADB privileges.

[LeEco Le Pro3 Guides, News, & Discussion] :
I just wanted to thank tsongming for the terrific advice he gave from recovering from a hard brick - both in this thread and throughout the forum. Yesterday I hard bricked my phone for the first time and thought that was it - time to change phone...the phone would not give ANY sign of life at all....but guys I brought it back to life following the guide! Thanks guys...I swear I am not going to flash anything until official pie :D:D enough with bricking my phone ahahahah
[LeEco Le Pro3 Guides, News, & Discussion] mbzhackers:
After a power cut-off during charging, I ran into a continuous boot loop even when trying to access recovery mode.

I can only access Bootloader and EDL modes.

I'm trying to follow this guide, but I noticed that there is a mismatch between the number of rawprogram xml files (7 files) and the patch xml files (6 files) :

Is that a normal behavior ?
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
Yes, don't worry about that, if you are getting an error go back anc check the steps. Its sound like you did not choose the port Alternately just choose Load *Xml- Choose All of the Ramprogxxxx at once by selecting all all

The process with QPST is usually very fast, if you have an issue you may not be in EDL mode. To be sure, press the volume up while connecting and the QPST program should recognize te port 9008.

Otherwise, just use the Flash 2.0 program, some people find it easier to use.

If you continue to have issues

You could have static problem which requires that the battery is disconnected and reconnected. Should you attempt to do this, do not use a hair dryer to remove the screen, the glue is too strong.

Instead you need to use a heat gun, you can find Leeco demonstration videos for removing the screen with the heat gun. Essentially you go around the edges of the screen for just over a minute> constantly moving.

When you remove the LCD, you need to then remove the heat shield, carefully, it also has a ton of glue on the edges. Below the heat shied is the battery and everything else.

Use magnifying glass and tweezers to carefully unplug the battery. It has a lego type connection and it is very easy to reconnect.

If you can successfully flash the Qfil with QPST and Flash 2.0, but still have the issue with not being able to boot to anything but fastboot. The only thing left to try is disconnecting the battery. If that doesn't work, you have hardware issues.

I seem to be having this error:

I've followed all instructions to a T on my desktop which has secure boot enabled thus not allowing me to disable driver signature verification, and on my laptop which driver signature verification is completely disabled. Both give the same error as well as this: "download start,url is:http://123.59.124.169/API/flashone/latest" not sure if its related. I suspect the driver is not allowing the Sahara server to communicate, likely because the driver available for download from: https://www.androidbrick.com/download/latest-2017-qualcomm-diag-qd-loader-windows-10-drivers-signed/ are possibly different. Otherwise how can I verify that the phone is in the right EDL mode, I had a flash failure that wiped out /boot so the device only powers on to what I assume is EDL mode and shows up in device manager as Qualcomm HS-USB QDLoader 9008, and the com port will change from 3 to 4 if replugged. The software recognizes this properly. The le_zl1_qfil_ufs_fix.zip file I have is SHA256: 0A76147E148F2DBE647F8A538380DE134C46F1C14B7BAEBA0A0F404969430EEE

EDIT: I read elsewhere that there is a certain amount of time you have to start the flash after getting into EDL mode. Holding all buttons for 30 seconds+ will force it to reboot, and after then the flash should work. For anyone else experiencing that issue, know that signed driver enforcement does not need to be enabled. Good Luck out there... and dont **** up /boot :P
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
First, Antivirus must be disabled. It will disable Leeco Qfil by removing files.

Next, you are not in EDL. Go to the first post below the OP and use QPST if Flash 1.9/2.0 are not working for you.

You have to select the port from within the program ( QPSY or Flash)

With QPST open, drivers installed, usb connected to PC but not the phone, press and hold the volume button up, while connecting to the usb. This will automatically place the phone into EDL

Finally, there are no issues with the drivers
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
I responded to your PM. I am certainly able to unbrick it for you if needed.

Let me know if you need that kind of help.

Although fixing it in person would be ideal, If the cost of mailing it is cost prohibitive. We can arrange to do it remotely
[LeEco Le Pro3 Guides, News, & Discussion] fatguy1121:
As mentioned in my edit, there seems to be a time window in which the phone is allowing EDL connections after booting. Holding all the buttons and resetting allowed the process to complete without a hitch.
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
Oh Okay, I was very tired when receiving your first PM, and I didn't see the edit. I am glad that you got it resolved.
[LeEco Le Pro3 Guides, News, & Discussion] blanktape:
First I want to thank OP for this amazing guide and relentless effort helping out the community. I was able to follow the guide and unbrick my absolutely dead x727. BIG THANKS!!!

I want to add a few of my findings that might help fellow XDA members to unbrick this device.

1. I experience this absolutely dead, no QFIL mode, no recovery no download mode and no matter how long I press all the buttons combination it just did nothing.

Solution: charge it and let it sit for couple hours, and have your 9008 Qualcomm driver install first, and try plug it your PC randomly see if it will detect. Magically it detected QFIL mode.

2. Remember to put the flash file in the root directory! C:/ (read OP's instruction carefully!)

3. Use USB 2.0 port not USB 3.0 port! I encounter an error like need to set "ZlpAwareHost='1' " in windows and I couldn't find anything related to this error. I recalled most of the technical program doesn't really work well with USB 3.0. I give my old PC a try and finally successfully flash the device.

Hope everyone unbricks their devices! And thanks to the OP again!
[LeEco Le Pro3 Guides, News, & Discussion] CrypticRoute:
First off, your efforts to help others are very much appreciated - Thank you!

2nd, i lost credentials of my old account here so just made a new one and linked to my google account and hopefully i won't lose it in future.

I have tried my best to follow your instructions to unbrick my X727 and unfortunately there's been no change. Please consider me as a novice when it comes to anything with smartphones. My first smartphone was Oneplus 1 and the reasons i bought is becuase (a) i received an invite and (b) reasonably priced. Just few months back, i can no longer use the phone because of poor battery performance. I finally bought LeEco Pro 3 thinking it would perform well and for my needs, it did till it died few weeks back and ultimately led me here for a fix. My bad for the long preface - i'll get back to topic now.

1. the phone shows up in my windows PC under "other devices" and listed with a yellow asterisk as "ADB Interface"

2. when i simultaneously press volume + - and power buttons, ABD interface disappears and "Qualcomm HS-USB QDLoader 9008 (COM 4)" appears

3. I used FlashOne2.0 and flashed the phone with "le_z|1_qfil_ufs_fix.zip" and at the end of which, i can see the last two lines of the log as

"Download Succeed

Finish Download"

after unplugging the cable and long pressing power button, nothing happens. There are no lights and screen remains blank.

I have read through your comments about alternate ways but i can't seem to follow them, especially the parts related to QPST. I have tried different cables and different USB 2.0 ports (thanks to blanktape) and no change. everytime the Flash finishes but the phone never turns on. Yes, the antivirus was disabled prior to any software install and i even turned off Windows (i have 8.1 pro) firewall.

did i miss something or there is no hope left for the phone? it does vibrate when long pressing the power button or trying volume + or - with power button.
[LeEco Le Pro3 Guides, News, & Discussion] mbzhackers:
Same thing with my X720.

After flashing with Qfil, it went on black screen.

I'm able to enter EDL and bootloader, and to re-flash it successfully in both ways, but that changes nothing.

I think there's a memory zone related to display driver or something like that, which has been erased by the first flashing, and we need to find the missing flash file for that zone and re-flash it.
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
I gave away my Le Pro 3 after buying a Mi8 so I will check the Le Pro 3 threads with kless frequency.

If you are seeing 9008 in the system device manager then you are in EDL mode. A that point you should be able to use Flash 1.9 or 2.0 ( some people find 1.9 will work when 2.0 does not) Try using Flash (1.9 or 2.0) first before using QPST .

On the OP I have step by step listed

On the first comment below the OP, I listed step by step for using QPST.

If you still have issues, I am willing to remotely connect to your computer to assist you. However, I will need to charge you a small fee for my time. Try again to just go back and read the instructions, the most important part is making sure that you are in EDL mode. From there it should be easy. ( most of the time) Don't get discouraged if it doesnt work, the issue could very well be your cable, or the computer port.

As I stated on the OP make sure that firewall and antivirus is disabled, while your are downloading the QFIL, Windows defender removes pieces of the QFIl damaging it, and it will not work.

Make sure you are using an account with admin privileges,

Make sure that any external hard drives are disconnected

Make sure that the OS is up to date

Update the drivers, and adb with the all in one tool, and give adb system wide privileges.
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
If you had a successful flash, then you may still be in EDL mode.

Use adb to boot to fastboot >>> What happens, if you still have a black screen you may have a different issue such as a bad battery, bad flex cable, or ( hopefully not) a damaged GPU.

Sometimes static can cause this issue, worst case, you may be need to remove the LCD and simply unplug the Battery and plug it back in again.

If you remove the battery, make sure that you use a heat gun ( instead of a hair dryer) There is a crazy amount of glue and you will damaged the LCD if the glue hasn't melted enough for the lcd to simply slide off.

You are right on. I have tried every method. I even installed a ROM from fastboot, used all in one tools and replaced twrp. It recognizes that its in ADB, ADB RECOVERY and FASTBOOT. It even recognizes that I am using a 727 now. But no matter what else I do, screen will not come on.

amd @ ampped101

If you guys tried both the QPST and flash 2.0 methods and you are having success but still no screen , it could either be the display or worse a broken cold solder connection on the motherboard ( hopefully not but it can be repaired by various TaoBao board repair shops for about $30)
[LeEco Le Pro3 Guides, News, & Discussion] mbzhackers:
Yeah, it could be.

Actually, what happened with me is that I hadn't any display issues, I was trying to resolve a boot loop problem through flashing with QPST or flash 2.0.

So, the minute before, display was OK, flashed successfully with QPST, and the minute after NO DISPLAY.

This is why I keep wondering whether my no screen issue is more related to the flashing process than to an eventual hardware failure.
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
If your QPST flash was successful, you are probably just stuck in EDL mode, which will give you those exact symptoms.

Plug the phone into the charge for 15 minutes and then press and hold the power button and volume down button until you boot into fastboot.

Once in fastboot use the All in one tool to check the bootloader and unlock ( if it will let you...it may) if you get a bootloader unlocked message, decrypt storage, with the All in One tool, then flash Recovery, with the all in One Tool.

Then boot into recovery , choose advanced wipe, select all, slide to wipe then reboot to recovery ( check boxes for TWRP Manager install) Once back in Twrp, format storage, type yes, reboot to Recovery again.

Now you should be fine to flash Rom, Gapps, and Root.

Here is the AIT Info:

The all is one tool is excellent and you can use it to install everything you want.
