Warning: This is a Unbrick post, your data is gone. This entire thread is about making the phone work again.

For the benefit of any new readers, I am reiterating , what I told [MENTION=7258498]the blackbull[/MENTION] privately and that any files that are needed for unbricking files are in the QFIL on the OP this thread . ( Future Readers: also, note the first couple of comments after the OP) You do not need to do anything with hex files unless its related to your changing your IMEI. To unbrick you have the Qfil /Flash method, The Qfil/QPST method, and the flashall.bat method.

Without a doubt the easiest and fastest method is to unbrick your device is to use the flashAll.bat method. There is zero doubts in my mind that this is the fastest and easiest way to unbrick any phone. I already bricked my new Mi8 recently and I had it up and running within 10 minutes using this flashall.bat.method and I have lost count on how many bricks that I have helped people repair, but my preference is now flashall.bat. It's much more straightforward and faster unbrick and I now firmly believe is the absolute best way to unbrick any phone.

Even though I have described the flashall.bat method on this thread a few times, I will briefly go over the basics here once again, if you want more details read this thread. Do not PM me, everything you need is already here. >>>>Clicking Thanks <<<<< or sending me beer money via Paypal would be appreciated Also, if needed, I will unbrick your phone for you.. for a fee, if that is easier for you. Frankly, I would rather that you just do it yourself, because it's good to cross that big hurdle off the list and do it on your own, so you will never have to worry about a brick again.

Here is how it works, download and unpack the 26s Fastboot rom.

Try using the( LE_ZL1_LEX720-CN-FN-WAXCNFN5902607031S-5.9.026S-FASTBOOT) fastboot rom, unpack it and use the flashall command.

Download the fastboot rom here : https://androidfilehost.com/?fid=673956719939836266

Instructions

Unpack the Fastboot rom file on your desktop.

With your phone in EDL mode, connect to USB 2 port ( If you don't know what EDL is , go read the OP)

Go to unpacked fastboot rom folder and search for a batch file called "flashall.bat"

Double click "flashall.bat"

You will see the terminal prompt open and begin the batch file process which will send each partition image to the phone one image at a time, 18 images in all so expect it to take 5 to minutes. ( This process automatically formats, and overwrites every partition)

When the process is finished the phone will automatically boot to the EUI system, wait, the first boot will take 5 to 10 minutes.

Now you need to go ahead and go through setup process again, and make sure you have prepared the phone for custom rom use.... You should know what to from there. ( Unlock the bootloader again etc)

Important things to remember

If using the flashall method, the Fastboot files must be unpacked on the desktop.

If using QPST or Flash 2.0 the Qfil files must be placed in the main (C:/) directory otherwise you will get errors

Although I would often use adb to erase the partitions first in the past, you do not really need to do that with any method, it's a redundant step.

Make sure that your PC is up to date, you have all needed drivers installed, if using Qpst make sure that you installed it in a admin account, okaying with admin privileges.

Do not use the computer for anything else while repairing your phone especially if it's an older computer.

Do not overthink using the Qfil, with Flash 2.0, w/ Qpst, or w/ fastboot.bat. You will likely be more stressed and forget a step. Relax, take your time.

It will definitely work unless you have a hardware issue.

If its a hardware, issue, Pming me will not help you, I have said everything that I know on this thread.

For unknown reasons, I often do not get notifications from XDA while using the Desktop app, If you need clarification you can PM to come here so it benefits any reader.

Choosing to NOT click Thank you button, kills motivation.

Good luck to you
