This could be several things. a parallel communication issue ( bad cable) A usb driver issue, or hardware such as the flex cables having a short, or your Le Pro 3 has a shorted usb card

Try this first

Remove any other peripherals , definitely use a different usb C cable and make sure that you are using a port on the back ( if using a desktop) Make sure that you are using a windows user account with Admin privileges and absolutely make sure that antivirus is disabled.

Finally, the Qfil posted on the OP is good, there are several bad QFILs out there such as the one on the other X720/X8727 unbrick thread, that file is corrupt.

One last thing, I have seen this issue in one version of Flash 2.0 only for it to work just fine in Flash 1.9 or vice versa.

Good Luck.
[LeEco Le Pro3 Guides, News, & Discussion] the blackbull:
I have the same results. I've followed the instructions as posted by tsongming and appears the error "STORAGE_WRITE_FAILURE" several times and flash process fail. What to do next please???
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
If trying the various versions of Flash ( ex: 1.9, 2.0 etc) m doesn't work, then try QPST.

QPST has an option to erase and format the boot partition, which seems to be your issue, you seem to have extremely bad corruption or maybe encryption. But unfortunately it could also be that your USB C connection has a short which keeps it from writing to UFS. In example, one pin may be shorted.

It's also possible that you will need to send the phone to a shop that has a JTAG programmer , which would allow the UFS to repartitioned, formatted and programmed. An electrical issue, such as a short could cause this type of corruption. Try QPST, if that doesn't work, you will probaly need to send to a repair shop. As I have mentioned on this thread try different cables, make sure that you are connected to a usb port with full power, disconnect external peripheral devices.

Finally, if you end up needing resoldering or JTAG work, you are going to be better off just getting another phone. The last time I looked I found X720's on Aliexpress for as low as $120 Good Luck.

when i press power key, volume up and volume down at the same time and plug USB with PC i have COm 3 qualquo HS-USB QDLOADER 9008

i want to restore the data from my phone but i don't how to do IT ?

I don't know if the methode inthread 1,2,3 i will recover my data (photos....)

Help please ?
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
You are on stock and you are unable to enter recovery mode?

To enter recovery you need to hold power and the volume up simultaneously. In recovery your data may be visible.

If not try the the flash.bat method 1st, and your data may survive. No guarantees.

Otherwise the data is gone, you may be able to recover it if you can find a repair shop that does data recovery. You need a special tool that connects to the jtag port on the motherboard.

Finally since you encountered the issue while using stock it's possible that you could have a hardware issue.
[LeEco Le Pro3 Guides, News, & Discussion] sunshine2004:
Thanks

But yesterday i try The first méthode with flash2.0 it ended well but the phone is still down .

So as far as it ended well i don't know if it's.not too late my data ? you told me that unbricking phone érase user data
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
It does erase your data.

I was talking about if you were still on the original rom, I would not count on restoring your data from the device. Hopefully you have google backup setup?

Regarding repairing your phone.

If you tried the flash 2.0 with Qfil and it ended well and the phone doesnt work still, then you have a hardware issue. As a last resort try flashbat method.

The best thing for you to do to restore the phone is the flash.bat method

Download fastboot Rom : https://androidfilehost.com/?fid=673956719939836266

Download and install adb/fastboot drivers.

Extract archive with adb tools on “C:\” drive.

Download fastboot rom that I mentioned in the 3rd post and extract it in to the same folder with adb files.

Make sure you’ve unpacked the downloaded archive

Boot your device in fastboot mode and connect to PC via USB cable.

Start “flash_all.bat”, wait until your device reboot and then remove USB cable.

If “flash_all.bat” file doesn’t work and terminal window is closed immediately, read the following information:

Press “Win+R” and type “cmd” in the opened windows, press “Enter”.

Use “cd” command to open folder with adb/fastboot files.

Drag and drop .bat file to terminal window and press “Enter”, now it should work fine.

My Phone is dying

Hi i was about to use my phone and upon pulling it out and pressing the power button the screen went blue and the hole phone shutdown before me. After awhile it came on and immediately i realize that its in a boot loop. At the time trying to repair it i only could have accessed the fastboot. if i try going into recovery mode it rebooted after awhile. I tried flashing twrp through fastboot but nothing happens. a few days has past and i am at the state were its dead and every time i put it to charge it is coming on then shutting down and not taking charge. its sad to see it messed up just like that but i hope i can get some help to repair it. i dont think its dead because it still some what comes on upon plugging it in.
[LeEco Le Pro3 Guides, News, & Discussion] Fredza12:
Hi.

First of all, thanks for all the info.

I am having the same ufs error and have tried different usb ports and different comupters etc. but still have the error

Let me give a quick breakdown of what happened , maybe it'll be easier to diagnose my issue:

I had lineage 15.1 microg working fine, i updated to 16.

A short while after this when leaving my phone on charge overnight, it sometimes used to be off. (i didnt know this at the time but it was probably in edl mode). I had to hold power for a few seconds for it to turn on.

One day the phone died(edl mode) while i was using it, i held power while it was on charge to switch it on. This happened a few times. over the week and seemed to happen more often.

To fix this i tried clearing cache and dalvik. and it seemed to be fine for a while.

a few days later i updated to the latest weekly and cleared cache and dalvik and a day or so after that it went into edl mode again and didnt switch on with holding the power button for 2 min etc.

I do clean my phone daily with a, perhaps not damp enough, tissue and reading your post about a possible short leads me to suspect water damage.

Thanks
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
Yes, It could be water damage or a short, a bad battery or it could also be simple corruption

Have you tried backing up all of your data and then completely wiping the phone, including "FORMATTING" not wiping ( Format Storage , type yes, reboot to recovery) After a fully clean wipe and format ( must reboot to recovery, anytime you format storage) try flashing a completely Rom such as AICP? If not, then I would definitely try that before doing anything else.

I would try to avoid charging your phone overnight, it's possible that the phone is getting to hot and shutting down to avoid thermal damage. Although, recent thermals in Lineage should protect your phone by shutting down cores at certain temperatures, it's possible that those files were corrupted or even encrypted by accident, (making them not work) that could lead to thermal damage. Its has happened, specifically in November 2018 a Nitrogen had an issue where the thermal wasn't linked and it caused hardware damage on several phones. ( It was an oversight/accident)

Another thing that you should try since you still have access to the phone, and you are able to flash roms ....

Try going back to stock for a while and see if the issue happens on the original stock Rom. For example EUI 21s to 26s. But not the newer 30s, it runs a little hotter. My mom's old X727 had a similar issue and I installed the EUI 26s rom and she used i for 2 weeks without any issues, from there, I installed Miui and she continued not having any issues at all. So we then moved her to AICP 14 and she continued without issues.

For the record, we have owned a total of Five Le Pro 3's in my family, and we recently bought new Xiaomi Mi8's, so we gave my kids the old X727's and those phones are still functioning just fine. One has AICP 14 and the other has Miui Pro

However, I have also had a couple of phones that ended up experiencing hardware issues, such as thermal damage, possibly broken solder and an issue with the usb card. However, I have also unbricked and replaced batteries in phones that people from XDA have mailed to me. Ivé seen similar issues and is a couple of cases changing the battery resolved the issue, on the last one , we changed the battery and the usb card.

Finally try another Rom, or try the fastboot flashall.bat method I have listed on this thread...that file is EUI 26S and with the phone in EDL mode you uncompress the file and then locate the fastboot.bat file and double click it or right click >open ( Its a batch file) It will erase the phone and send all of the factory images to the phone, one at a time. If you have a corrupted partition, it will absolutely be overwritten, from there it's possible that everything will work fine and you can go on to reinstall TWRP / Root and then go back to your Rom of Choice.

Good Luck

Sorry to hear about your issue.

First let me give you an XDA tip. Either click to reply to someone's post or type @ and their name no spaces, this way that person or if you were intending to talk to me, I will get the message, otherwise, I will never see it unless I come to this thread and I bought a new phone so I rarely come here.

If you have fastboot and you successfully flash TWRP and you cannot access it then I Hate to tell you that you may, very likely, have a hardware issue. Read the other post that I just made above , it has instructions for flashing the fastboot flashall.bat file. Your data is gone, the best thing that you can really hope for is to restore the phone to the stock rom by using the flashall.bat file or qfil. with your issue, I would try the flash.all method, the file is on the thread I posted it several times, including just a few days ago, and it's at the bottom of the OP ( To be clear you want the fastboot flashall file and not the standard stock rom, it's also posted a couple of days ago)

If that is successful, then you will be able to fully restore the phone to being useable again.

Best Wishes
[LeEco Le Pro3 Guides, News, & Discussion] TitanFactor:
Hey thanks for the tip and also for replying. The link that you posted for the file on android file host say no available mirrors can you probably re upload i don't know if its because of my location. Thanks :good:

To use QPST option to erase and format flash a .hex file is requiered. Where to find that file???
[LeEco Le Pro3 Guides, News, & Discussion] peed_neslo:
I have tried the flashall.bat by mauronofrio (zl1, x720 stock 26s), to be sure, that I am having hardware issues.

Looking obviously good, but a the beginning after bootloader unlock before sparsing the system, i get a "Invalid sparse file format at header magic".

what does it mean? after process finished, phone is booting and looking good... lets see if strange behaviour continues...
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
I noticed that you didn't click thanks for this extensive guide. While it may seem petty, I spend a lot of time trying to help people, and I would appreciate clicking thanks if I helped you. Especially, since I no longer use this phone and I am only motivated to do work for free by watching my thanks statistics improve or cash will also suffice. So please click thanks or donate, I really don't care which one you choose.

With all of that being said, the invalid sparse is nothing, you are fine.

Also mauronofrio is hosting the file, there is no reason for me to re-upload it when I found one already available on AFH. But yeah, the file was created by Leeco, and almost all fastboot roms have flashall.batch scripts.

Hi.

I'm still reading a lot of threads, but looking this one has fresh comments and that [MENTION=7672955]tsongming[/MENTION] is still helping with this, decided to post a quick post here.

First of all, I want to make clear something, the phone WON'T go into EDL unless you have installed the qualcom recovery drivers. The phone will only vibrate when power button is hold fore more than 6 seconds, but PC won't even see it when you connect it (literally, I used usbdeview and no new device is detected when phone is connected withouth the drivers), but once you install the drivers the PC will begin to see the phone.

Once the phone goes into EDL, you can go into a primitive recovery and fastboot mode using the usual methods (you can see a more detailed description in my thread, linked in the next paragraph).

Those drivers are the ones that makes all kind of magic be possible. Maybe there are other methods, but I haven't seen them yet and I'm desperatly looking for them now =/

Second, if your phone can go into EDL, it can go into recovery and fastboot. Yes, you can recovery your info before flashing your phone! Or at least in my x722 was possible. I left a little guide in the thread where I'm asking for help.

https://xdaforums.com/le-pro3/how-to/help-debrick-le3-pro-x722-flashing-t3948150

Last, I tried to revive my phone by flashing one bye one the images of the flashall.bat package of [MENTION=7672955]tsongming[/MENTION], although I may have been wrong in not asking first tsongming one thing, because the zip was meant for the x722 (and it was on the x722 guide), but the name of the file is "LE_ZL1_LEX720-CN-FN-WAXCNFN5902607031S-5.9.026S-FASTBOOT.zip", well, that x720 in the name is my big issue (although the rest of the name seems to be of the x722 rom). Short story is that I only flashed devcfg.mbn and devinfo.bin and now I've lost access to EDL mode and recovery/fastboot aswell too.

I hope [MENTION=7672955]tsongming[/MENTION] could look at my thread ( https://xdaforums.com/le-pro3/how-to/help-debrick-le3-pro-x722-flashing-t3948150 )

And I want to thank him because most of the unbricking info here is because of him.
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
My thread was written specifically for X727 and X720. The fastboot rom is only for the X720 and X727.

You will need to download the X722 fastboot rom, and use it to use the flashall.bat method. I am certain that this link still works and its directly from Leeco : http://bug.letv.com/cn/download/phone/80 (Message for anyone downloading this file, if not bricked) the linked file will relock the bootloader, you have been warned. For bricked users, you can restore the phone using the flashall.bat method with this rom. ( steps are mentioned in previous comment)

Next this thread was made for the X722, https://xdaforums.com/le-pro3/leeco...ides-development--and-mods/qfil-x722-t3846553 and as far as I know F.J.V still supports his thread.

The worst thing that the X720 rom will do to your phone is brick it, so you are back to where you started, just use the correct rom to unbrick

Entering EDL

Typically, just holding the up and down button, along with the power button simultaneously will put you into EDL mode, this is when the phone vibrates.

As far as getting the computer to recognise EDL, you were correct about installing drivers, and this is mentioned on the OP. Your goal is to see USB port 9008, the computer will not otherwise see the phone yet.

Another method for entering EDL is to install QPST and QPST drivers, along with android drivers, disable firewall and antivirus, use an admin account etc. Once all of that has been done. With the phone disconnected open QPST, and hold the volume key up while connecting the usb cable to the back of the computer on a USB 2 port, the phone will automatically go into EDL..now you should be able to unbrick with success.

[LeEco Le Pro3 Guides, News, & Discussion] tylerciggy:
Thank you very much for your answer.

I still can't connect in EDL mode. I tried the 3 buttons, Vol up + power + cable, I even tried in another computer (although the acer one may not have been the best idea). I'm gonna try later an hdd with win7, I just havent did it because I'm busy reading.

I used the "QDLoader HS-USB Driver" to be able to enter into EDL. I assume the QPST drivers are something different ?

I will post my results later.

Thanks again for your quick response.
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
Here is my Megadrive with QPST and QPST drivers.

Although you should only need the Relink driver, and Qualcomm_Flash_Image_Loader. Install all of them, it will not hurt to install the IMEI drivers in case you ever need them in the future.

https://mega.nz/#F!gEwBFSCQ!G9AcOHNtYUqMHfqpX6vfAQ
[LeEco Le Pro3 Guides, News, & Discussion] tylerciggy:
Well, it seems the QSPT drivers are just the same as the Qloader ones (QDLoader HS-USB Driver).

I believe the key is in the point number 1 of your instructions

"1.- turn off your phone"

I don't have a way to "see" if my phone is turned off. Although I can know that it is not off because it keeps warm as long as it has charge.

Yeah, I tried many times letting it discharge (or I think so, because it gets cool) and try the "vol +, vol -, usb cable" method, but it only vibrates once when connected to usb and is not being recognized... BUT sometimes it does that while still warm, it just requires a lot of time of being disconnected.

I had it connected into a 7 usb3 hub connected in a usb3 port in the back of my motherboard and I never got a disconnection, even when copying around 20gb of data. Yeah, adb pull got stuck many times, but the PC never got a disconnection, I just could instantly repeat the command and the adb pull instantly began to copy again. As you can imagine by this comment, I already tried in the usb 2 motherboard ports with no response either.

I want to mention that when I fastboot flashed the dev.imgs, I didn't disconnected the cable and when the phone was not recognized by the pc I knew I was in big troubles. I tried to go into recovery/fastboot withouth disconnecting it, but as you can already imagine, I had no luck with that.

I tried many versions of the QPST (including the both you provide in your threads and in the link you just gave me). but it still can't see my phone =/
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
If the phone is in EDL mode, to turn it off just press and hold the power for about 45 seconds. There is another option to be sure that you are in EDl mode, you can buy an EDL cable on Amazon

https://www.amazon.com/GPG-EDL-Cable-2-in-1/dp/B06XXCLMGM

Sometimes, you need to get a little more drastic and remove the screen and unplug the battery then press and hold the power for 20 seconds, to full discharge any remaining power. If you read the X722 unbricking board you will see that several people with X722's had to do this step to be finally able to use the Qfil.

The only files that you can use from this thread is QPST and Flash 2.0, or the fastboot file that I linked for you on my last comment.

Don't the Qfil, on my thread it will not help you at all.

I am sure that I made this clear on the OP this thread for X720 and X727, the Qfil is only for X720 and X727, the Qfil linked on my thread will not help you. The only working Qfil is on the X722 thread and FJV, had to actually make it himself, since a Qfil for the X722 didn't exist until he hacked one together using the Mav2 Qfil, merged with 18 images from the X722 EUI 26s fastboot rom.
[LeEco Le Pro3 Guides, News, & Discussion] tylerciggy:
Yeah, it was my mistake because I was already too tired from being reading too much things, although I really didnt flash the qfil, just one img file.

I'm gonna try to find the EDL cable in the local market, disconnecting the battery is my last option, I believe is too risky to do it to may achieve nothing. If so, I'm probably giving it to a technician to do it, but it's going to cost me like $25usd...

I'm still going to keep reading about entering the EDL mode. I asked a friend with a working x526 and he couldn't make it go into EDL. I asked him to do so to verify the button combination and it seems sometimes it's not that simple.

Thanks again for your assistance.
