Think I did the title pretty well, I can only access fastboot (Before you say anything I've already tried this guide:http://forum.xda-developers.com/hua...ow-to-unbrick-huawei-p8-failed-t3260704/page1) all it gets me is the screen to light up (black) that's it. At this point I have no clue how to bring it back, any useful tips or ideas would always be appreciated. Thanks.
EDIT: It would be helpful if anyone knew a way to unlock the bootloader through fastboot
EDIT: nvm unlocked the bootloader through adb
EDIT:Installed TWRP through FASTBOOT
EDIT: Had the future rom downloaded, installed through SD card. DEVICE BOOTS.
EDIT: Tried dload method, went back to square 1 (Device would only backlit screen on boot, bootloader locked) Repeated steps and used the Huawei P9 Updater 2.0 by Hajuuk (Godbless) IT WORKS. Currently on C185B170 will update to B180 and from there to Android N. IF anyone has a similar problem feel free to ask.

Hi, I have problem. I have two Huawei P9. One is L19 and the other is L09.
My L19 is the C900
My L09 I do not remember what it is ... the problem is that it is no system, it only turns on fastboot recovery mode. I've tried combo keys with dload but it does not work or does not recognize. By Hisuite says that the model is not supported. Finally I tried the Firmware Update program by hajuuk https://forum.xda-developers.com/p9-...dater-t3435878 I used several firmwares inside the L09 option but in the middle of the installation it gives error.
I need to find a way to enable the OEM so I can flash boot.img, recovery.img and system.img because I can not flash anything at the momento because it gives the Not Allowed command.
The status is Bootloader locked and FRP locked.
I do not know what to do, I have no ideas.

I think there is not solution for this problem. We have to wait. (I have the same problem but in Al00 running Al19 rom)
How do you check for FRP lock on a Huawei phone just curious.

Okay to unlock the bootloader, go into fastboot and plug in the USB to your computer, then by either using SRK tool or adb you need to flash this command: fastboot oem unlock (insert bootloader code) *don't put brackets* if you are unaware of your bootloader code then I cannot help you, however if you do know it, then once you unlocked the bootloader flash system.img and stuff to see if that works for you

That's weird, OEM unlcok was also switched off in developer options for me, yet this still worked, can you tell me exactly what the error code says?

I've tried some command in fastboot mode but there's always an error: Remote: command not allowed.
I can't do anything with fastboot mode
1. Try to force update with Power Button + Min Vol Button + Max Vol Button, liked you said this isn't working try to do the button combination with the phone connect it to the PC; in my case some times dload din't works after I connected the phone to the computer.
2. Other thing, something happend if you turn of the phone and leave Max Vol Button pressed, you should be entering to eRecovery.
3. Remember that sometimes enter in eRecovery mode requires to the phone be turn off otherwise you can't access to Recovery. So if this is the case follow bullet #2 and them #1.
PD: OFC I'm assuming you already have the dload folder with an compatible version of stock ROM on your SDCARD. If you don't have any version tries this one: https://forum.xda-developers.com/p9...dload-file-p9-eva-l09-b136-t3382818?nocache=1
Hope I helped you, I already bricked twice my P9 corrupting System Table Partitions.

If you did the change of Unlock OEM before the bricked in an previous authorized computer you will still have rights for, otherwise new Android Security features is going to rejected the request.

Any help would be greatly appreciated
I have a P9 L09, i have unlocked the bootloader, flashed TWRP recovery, and started flashing some roms. I have succesfully flashed a cyanogenmod, and it booted properly, but when it started it asked me for a password which i did not know, so i google searched and found out that it is a common issue and i need to wipe data from recovery. I tryed that but it did not work it says failed, and nothing works in the wipe advanced section, beside system. And also in the custom recovery it says that the internal storage has 0MB ! I was able to put other custom roms on the SDcard and flash them, they booted but every single one asks for the password.. I then tryed to install stock rom with the dload method, but it crashes and 40% , and i tryied the System Recovery option in HiSuite and it says it is not compatible with my device. Any help would be greatly appreciated! Thank you!

Hello. I have the same problem. I have my unlock code but in fastboot, adb command says it failed. Sorry for bad english. What can i do?
FAILED: REMOTE COMMAND NOT ALLOWED FINISHED.
Same problem on my honor &x locked bootloader and bricked. unlocking the oem like you said above does not work
Hi,
I have a P9 here I'm was asked to repair. I think it is kind of bricked and I hope some one can help me to unbrick it.
According to the auto dc-unlocker identification:
Found Phone : EVA-L09
Firmware : EVA-L09C432B386
FB LockState: LOCKED
USER LockState: LOCKED
So, bootloader locked and FRP locked. I don't know if the Firmware version above is right. All I know is that some Update.app files were flashed to the state of the phone now and before there where bootloops while the start animation and stuck boot with black screen.
At the moment I can do:
- turn on to see only the first huawei log with "powered by android", then nothing happens
- I can not enter eRecovery or update for Update.app
- I can only enter fastboot
I have the unlock code for the bootloader. I can not commit any fastboot commands (oem unlock, flash, etc) all is blocked with:
FAILED (remote: Command not allowed)
The locked FRP should be the reason for this.
I think OEM-unlock and usb debug from developer section was not enabled as the phone was usable. adb commands like "adb reboot bootloader" fail with
error: device '(null)' not found
fastboot devices shows the device
I have tried to uncharge the battery and then try to enter other modes than fastboot. No luck with that.
Do I have any chance to unbrick it without paying for the dc-unlocker/phoenix?
Can I do something with SRKTool?
If I have to use unlocker,
- do I have to unlock the bootloader?
- should I flash the same firmware that is now on the phone (B386) and where can I find it? (found only 1000 other versions until now)
Hope for answers
I've gone through that before, but ended up using DC-Phoenix to unbrick it when it's FRP and bootloader locked. Cost me about $15. There is a post on how to do this but I'll have to search for it again.
Here is the post I used:
https://forum.xda-developers.com/showpost.php?p=71767614&postcount=7
I guess you enter fastboot by Vol- and Power?
Not sure if the following method could help you with, but you can analyze before you go for dc-phoenix:

So you can not update via dload method? Did you try booting into recovery (not Recovery)? And you can't update with Update.app, you need to flash update.zip and full_update.zip via TWRP or Recovery. What wanted the owner of this phone to do, that he bricked it ?
Thank you all for your answers. Like I tried to describe: I was not able to access any other mode than fastboot.
"was able": I used DC-Phoenix now and it worked just fine.
Little confusing is that in all tutorials, even the on on the DC site, the UI of the tool is different.
But that's now Problem. The current Version is lot easier. Just "Standard Mode", select Update.app (full), Click Update.
The Phone gets flashed with fastboot, DC will restart it to update mode and will flash again. All automatic.
Really easy.
so you paid 15 USD ?

Yes I did, and it worked.
THIS IS NOT GUARANTEED TO WORK! If it does not work, feel free to let me know here and i will do what i can to help, but remember I probably can't help everyone.
IMPORTANT: ON XDA-LABS APP THIS POST IS KINDA BROKEN IDK WHY SO LOAD IT IN BROWSER!!!!
If the guide worked for you, please hit thanks button! If you are generous and want to donate pm me
What this can fix:
When booting, you get this error:
Func NO : 10 (boot image)
Error NO : 2 (load image)
When booting to recovery, you get this error:
Func NO : 11 (recovery image)
Error NO : 2 (load image)
Bootloops
Can't boot into fastboot
Can't boot into recovery for other reasons
Can't boot to system for other reasons
ETC...
First thing first, there really isnt a way to keep your data so expect it all to be gone, unless it is saved on an external sd card. Also, this guide is specifically for the PRA-LX1 model, however it might work with other p8 lite 2017 models and a similar method may work with other huawei phones.
Requirements:
The device boots in to fastboot mode. (If it does not, scroll down to problem 1)
You have a pc with a usb port and fastboot/adb installed
You have a micro usb to usb cable.
Unlocked bootloader and oem unlock.
Micro sd card
Problem 1: Can't boot into fastboot?
Try this:
1. Make sure device is fully powered off
2. Connect device to any pc.
3. Press and hold volume- and power button at the same time until your screen turns on.
If this doesn't work then unfortunately i can't help...
Problem 2: Only fastboot boots, but not recovery or os:
Lets start by flashing TWRP...
If your device was on android nougat (7.x.x) or the rom you were flashing was nougat based then do this:
Download this file:
https://drive.google.com/file/d/1TjNHI9FNdwQS2HphsjGfQCHKephibiKn/view
Boot into fastboot on your phone and open fastboot on your pc
Type: fastboot flash recovery *Nameofrecovery.img*
-----------------------------------------------------------------------------------------------------------------
If your device was on android oreo (8.x.x) or the rom you were flashing was oreo based then do this:
Download this file: https://drive.google.com/file/d/190zqju8ZmwZCzI4WXtujgKLFXvvuWTk8/view?usp=sharing
Boot into fastboot on your phone and open fastboot on your pc
Type: fastboot flash recovery_ramdisk *Nameofrecovery.img*
https://www.mrviking.co.uk/440246340
Problem 3: You can only boot into fastboot and TWRP recovery:
Thats OK! Heres how to restore the phone:
IMPORTANT: THE FILES LINKED HERE ARE ONLY FOR PRA-LX1 DEVICES! If your device has a different model number, or these files did not work for you, follow this guide to get files for your device: https://www.mrviking.co.uk/440246340
This will also update your device to android oreo!
Put the micro sd card in your pc.
On your pc download these files:
https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279 (Download 0.3)
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1194/g104/v148634/f1/full/update.zip
http://update.hicloud.com:8180/TDS/...altice_all/update_full_PRA-L11_altice_all.zip
http://update.hicloud.com:8180/TDS/...34/f1/full/public/update_data_full_public.zip
Now Rename update_full_PRA-L11_altice_all.zip to update_all_hw.zip
Also rename update_data_full_public.zip to update_data_public.zip
Put all four files: update.zip, update_all_hw.zip, update_data_public.zip and HuRUpdater_0.3.zip into one folder on the external sdcard.
Take sdcard out of pc and put it into phone.
Boot into twrp tap on mount and select all partitions
Make sure 'mount system read only' is NOT checked.
Go back to twrp home
Go to install, find the huruupdater zip file
Flash ONLY hurupdater, DO NOT FLASH ANY OTHER ZIPS.
Follow instructions on screen.
Reboot to system and wait for the device to boot.
If it didnt boot, dont worry:
Go back to fastboot mode on your phone and pc, and download this file: https://drive.google.com/file/d/1daIos0yagHk9Kg-5hXLDwNYDHjP_N0EM/view?usp=sharing
Flash it with fastboot using:
fastboot flash recovery_ramdisk *Nameofrecovery.img*
now boot into recovery wipe cache wipe date/factory reset reboot to system
If none of this worked, try this last resort. (Likely won't work but it is worth a shot)
Firstly, place your micro sdcard into your pc. Create a folder called 'dload' in the root of it.
Now, locate the firmware files you downloaded from firmware finder.
Open the main update.zip file and extract the 'UPDATE.APP' file to the 'dload' folder in your sdcard.
Place sdcard back in phone
Make sure phone is powered off. (Can't power it off? Unplug anything connected (charger, pc, etc...) and hold the power button until screen goes black)
Hold all three function keys (VOL+,VOL- and POWER) until screen turns on.
Hope it works and wait
If it worked, please hit thanks button! If you want to donate pm me.
If it DID NOT work, post a reply here and either me or someone else will try and help.
Thanks!

Always use TWRP from OP
And if its not working, try Flashing Stock recovery and boot it and do tap some options e.g. reset/ clear cache etc. ( I got my mobile fixed via this method as Internal Memory got corrupted because of incompatible TWRP )
For problem 1 fix : Fully shutdown , connect the phone to via usb to pc , and fast hold down the volume - . Cheers
Edit : or the same : usb , power and volume - till you see the huawei logo , then just hold volume -

Force shut down the device (Hold power button) if it is on.
Connect to a pc
Hold down POWER and VOL- buttons untill screen turns on
If you see a screen with an android robot saying FASTBOOT at the top let me know, if not tell me that :good:

Wow thats a pretty bad brick. First try to boot to recovery like this:
1. Make sure phone is off.
2. Hold power and volume up until screen goes on.
3. When screen goes on quickly take fingers off buttons.
If it does not work, I think your only hope is to use funky huawei.
Do what this guy did (read the bottom of the first post)

yes, i've.
phone relocked and frp lock. really bad state.
all caused after a magisk installation via magisk manager (this brick my boot).
my giant error, test to install without verify if frp still unlocked and this has caused a giant brick :/
i need a way to bypass-removed frp, and unlock again bootloader.
then, reinstall twrp and recovery my system.
all is in standby cause frp
yes, i know, exist some windows (i use debian) pay app, but 19€ for "just a click" to a device that atm cost about 130€ ... i think isn't a great price.
i really cannot understood why huawei cannot make a real recovery tool.

edit, thanks to dc unlocker and some test, now i've bootloader unlocker, but frp remain locked - then, i still cannot fix.
any help? :|

Can you update to stock through erecovery via wifi? I had my phone frp locked + bl locked + bricked system. eRecovery was the only way out to get into a working system.
The unlock tool that costs too much is b.s and only works if it was locked because of Google Play account (tried it, did not unlock my frp).
After erecovery update and having a system, google play account was also locked because of stock firmware, this time I used the unlock tool. I used firmware finder afterwards for forcing an oreo update (because bl unlocking was grayed out). After oreo update, i enabled bl unlock from dev options and unlocked my bl again through fastboot. frp got unlocked along the way, i forgot when.
i can access in eRecovery, but when i check to download by wifi i still receive: "Getting package info failed" :/
-
via dload (8gb sd in fat 32 with only dload folder and old release UPDATE.APP inside it - but tested with more...) stuck for minuts at 5%, then reboot!

If the guide worked for you, please hit thanks button! If you are generous and want to donate pm me
What this can fix:
When booting, you get this error:
Func NO : 10 (boot image)
Error NO : 2 (load image)
When booting to recovery, you get this error:
Func NO : 11 (recovery image)
Error NO : 2 (load image)
Bootloops
Can't boot into fastboot
Can't boot into recovery for other reasons
Can't boot to system for other reasons
ETC...
First thing first, there really isnt a way to keep your data so expect it all to be gone, unless it is saved on an external sd card. Also, this guide is specifically for the PRA-LX1 model, however it might work with other p8 lite 2017 models and a similar method may work with other huawei phones.
Requirements:
The device boots in to fastboot mode. (If it does not, scroll down to problem 1)
You have a pc with a usb port and fastboot/adb installed
You have a micro usb to usb cable.
Unlocked bootloader and oem unlock.
Micro sd card
Problem 1: Can't boot into fastboot?
Try this:
1. Make sure device is fully powered off
2. Connect device to any pc.
3. Press and hold volume- and power button at the same time until your screen turns on.
If this doesn't work then unfortunately i can't help...
Problem 2: Only fastboot boots, but not recovery or os:
Lets start by flashing TWRP...
If your device was on android nougat (7.x.x) or the rom you were flashing was nougat based then do this:
Download this file:
https://drive.google.com/file/d/1TjNHI9FNdwQS2HphsjGfQCHKephibiKn/view
Boot into fastboot on your phone and open fastboot on your pc
Type: fastboot flash recovery *Nameofrecovery.img*
-----------------------------------------------------------------------------------------------------------------
If your device was on android oreo (8.x.x) or the rom you were flashing was oreo based then do this:
Download this file: https://drive.google.com/file/d/190zqju8ZmwZCzI4WXtujgKLFXvvuWTk8/view?usp=sharing
Boot into fastboot on your phone and open fastboot on your pc
Type: fastboot flash recovery_ramdisk *Nameofrecovery.img*
https://www.mrviking.co.uk/440246340
Problem 3: You can only boot into fastboot and TWRP recovery:
Thats OK! Heres how to restore the phone:
IMPORTANT: THE FILES LINKED HERE ARE ONLY FOR PRA-LX1 DEVICES! If your device has a different model number, or these files did not work for you, follow this guide to get files for your device: https://www.mrviking.co.uk/440246340
This will also update your device to android oreo!
Put the micro sd card in your pc.
On your pc download these files:
https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279 (Download 0.3)
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1194/g104/v148634/f1/full/update.zip
http://update.hicloud.com:8180/TDS/...altice_all/update_full_PRA-L11_altice_all.zip
http://update.hicloud.com:8180/TDS/...34/f1/full/public/update_data_full_public.zip
Now Rename update_full_PRA-L11_altice_all.zip to update_all_hw.zip
Also rename update_data_full_public.zip to update_data_public.zip
Put all four files: update.zip, update_all_hw.zip, update_data_public.zip and HuRUpdater_0.3.zip into one folder on the external sdcard.
Take sdcard out of pc and put it into phone.
Boot into twrp tap on mount and select all partitions
Make sure 'mount system read only' is NOT checked.
Go back to twrp home
Go to install, find the huruupdater zip file
Flash ONLY hurupdater, DO NOT FLASH ANY OTHER ZIPS.
Follow instructions on screen.
Reboot to system and wait for the device to boot.
If it didnt boot, dont worry:
Go back to fastboot mode on your phone and pc, and download this file: https://drive.google.com/file/d/1daIos0yagHk9Kg-5hXLDwNYDHjP_N0EM/view?usp=sharing
Flash it with fastboot using:
fastboot flash recovery_ramdisk *Nameofrecovery.img*
now boot into recovery wipe cache wipe date/factory reset reboot to system
If none of this worked, try this last resort. (Likely won't work but it is worth a shot)
Firstly, place your micro sdcard into your pc. Create a folder called 'dload' in the root of it.
Now, locate the firmware files you downloaded from firmware finder.
Open the main update.zip file and extract the 'UPDATE.APP' file to the 'dload' folder in your sdcard.
Place sdcard back in phone
Make sure phone is powered off. (Can't power it off? Unplug anything connected (charger, pc, etc...) and hold the power button until screen goes black)
Hold all three function keys (VOL+,VOL- and POWER) until screen turns on.
Hope it works and wait
If it worked, please hit thanks button! If you want to donate pm me.
If it DID NOT work, post a reply here and either me or someone else will try and help.
Thanks!

No problem! Glad to hear it works
I've made a tutorial 1 day before you ^^
Hello i've made a tutorial on my thread for my solution to unbrick it so if you need to unbrick your phone with a different method
you can use my tutorial it has worked perfecty on my p8 lite 2017 and now he's on oreo
my phone personnaly was totaly broken i flashed some random things on my phone etc this is working 100% cause you are about to clear all the old android system for the new oreo one so for the peoples who got the same problem than me and got stuck
on the fastboot&rescue mode when VOLUME- + POWER for like 5 seconds with the phone off
(for the peoples who can't power off your device you can download the "universal fastboot and ADB tool" app and then click on reboot phone in the fastboot part)
the solution is to :
-Download the rom stock Oreo android 8.0 stechguide.com/huawei-p8-lite-2017-b370-oreo-firmware/
-exctract all files from the HuaweiUpdateExtractor find it on google it's easy just download update.zip
-extract and put the UPDATE.APP in the HuaweiUpdateExtractor
-run srk tool for huawei
-type 000 and press enter
-and now you have to flash all partitions that you have received from HUE commands are here:
[dont worry if some of theese are not working it's because certains commands are not allowed to use and certains commands are out of date :/ but dont worry the phone will boot correctly after ]
Code:
fastboot flash cache CACHE.img
fastboot flash crc CRC.img
fastboot flash curver CURVER.img
fastboot flash dts DTS.img
fastboot flash efi EFI.img
(i'm not putting erecorery imgs cause we cannot touch them it's an ultimate security from os :) )
fastboot flash fastboot FASTBOOT.img
fastboot flash hifi HIFI.img (only if you are the wifi is not working ;) )
fastboot flash kernel KERNEL.img
fastboot flash modem_fw MODEM_FW.img
fastboot flash modemnvm_update MODEMNVM_UPDATE.img
fastboot flash odm ODM.img
fastboot flash package_type PACKAGE_TYPE.img
fastboot flash product PRODUCT.img
fastboot flash ramdisk RAMDISK.img
fastboot flash recovery_ramdisk RECOVERY_RAMDIS.img
fastboot flash recovery_vbmeta RECOVERY_VBMETA.img
fastboot flash recovery_vendor RECOVERY_VENDOR.img
fastboot flash sensorhub SENSORHUB.img
fastboot flash system SYSTEM.img
fastboot flash teeos TEEOS.img
fastboot flash trustfirmware TRUSTFIRMWARE.img
fastboot flash vbmeta VBMETA.img
fastboot flash vendor VENDOR.img
fastboot flash verlist VERLIST.img
fastboot flash xloader XLOADER.img
Now you have loader all partitions of an huawei p8 lite 2017 android 8.0 gg !
you just have to make a fastboot reboot to reboot your phone and enjoy !
notes:Everything is working properly after 3 day of use not any missing data some calls bugs but nothing hard
you will loose your TWRP recovery mode AND DO NOT INSTALL ONE OF THEM FOR NOW they are outdated for oreo wait some months (september on some sources)
you will loose all your data and the root (some sites prupose root methods for oreo p8 lite 2017 (and soft root this time :laugh:
idk about the bootloader but i keeped my imei number ^^
Thanks for your time and if anyone got questions i'm still here ^^

My phone is bricked and I can not do anything with the fastboot.
Let me tell you what happened to me. I was flashing the hurupdater and I did not notice that the name of another file had to be changed, I changed the name of only one. I uploaded the system, but as I blushed, it forced me to miss the specified file, later I figured that the folder names did not match.
And the system booted, and a lot of applications was missing. For example, camera, keyboard, alarm ..
And I do not know why, I run dload, although I forgot what data is on it, the dload is started and done to the end.
Here it is BRICK
After that, I can only enter the fastboot, or if I let it go through the system, it stuck to me
"your device cant be trusted ....
Your device is booting now "
Bootloader was unlocked, it did not lock me up, I checked through fastboot, something fastboot oeminfo and it says to me that the bootloader is unlocked. But I definitely tried to unlock it again, I have a bootloader code, and it tells me I've already unlocked it.
Only fastboot works for me, dload can not, through fastboot I tried recovery to insert, but can not. The only ottered door is fastboot, but I'm flashing boot.img and system.img and recovery.img and twrp.img I can not run anything except fastboot..
Help!

Hi
I want to flash my Mi 9 Lite by MiFlash v2020.3.14.0 in fastboot mode(Fastboot Update).
My device is unlocked and unroot, I download the latest official tgz ROM and decompress it and run MiFlash and past the ROM address to the MiFlash tool, after refreshing my device is recognized , I click on flash button, but MiFlash tools show me "error:not catch checkpoint (\$fastboot -s.*lock).flash is not done"
Even by going to the configuration menu and removing the text "\$fastboot -s .* lock" from the checkpoint and OK it and then clicking on the flash, the program will quickly show the flash done and show flashing is success, but it is not actually flashed!!!
I have already installed Minimal ADB Fastboot v1.4.3 and device driver, developer options and usb debugging is on.
in CMD I run fastboot devices command and my device is recognized
I even installed TWRP recovery by adb commands
what's the solution?
Why MiFlash does not flash the official ROM and shows error?
How can I flash the official ROM(*.tgz file) in Fastboot?
thanks.

Probably you did something wrong trying to remove that text, you don't need to remove it if your bootloader is unlocked.
You can flash it directly using fastboot commands, or you can flash it through EDL mode too.

Thank you for your answer
My device bootloader is unlocked, I also saw and checked it. I did it both when it was text and when I deleted the text, but in fact nothing happened and my device did not flash and only remained in the same fastboot mode until I restarted it and it started normally.
I even tried the new version of Mi Flash Tool v20210226 and got the same result as before.
I downloaded 3 different versions for mi 9 lite from the official site, https://c.mi.com/oc/miuidownload/detail?guide=2, and as I explained, it was.
even I downloaded other regional Roms but the same result...
you said : You can flash it directly using fastboot commands, or you can flash it through EDL mode too.

Mm, Maybe you are trying to use the fastboot ROM through Mi Flash tool without firstly decompressing it?
You need to decompress first the tar.gz file, you will find inside all the image partitions, the scripts needed.
As you can see in the images in this thread, the files have to be accessible for the tool to can load them https://androidmtk.com/use-xiaomi-mi-flash-tool
This is the simplest way, using Mi Flash tool, you can use it in fastboot (if unlocked) or in EDL mode (no matter locked or not). Take care to not choose the option "relock" device if you don't want to do that.
For the fastboot commands you require to decompress the files and execute simply fastboot flashall -w this will format data and update your device. Sometimes this simple command doesn't work, then you can edit the flashall.bat file, line-by-line, to the scripts being executed.

I decompress first the tar.gz file! I wrote all my actions in post 1 and post 3.
I followed the instructions written on the official Xiaomi page(https://c.mi.com/oc/miuidownload/detail?guide=2)
how can I flash the official ROM in fastboot mode or any other mode?
Please write a guide for me. my device is Mi 9 Lite.

You can flash through EDL mode the same way as it is in the guide you followed, the main difference is that you have to put your device in EDL mode to perform the operation.
As your device is unlocked you can put it in EDL mode without the need to disassemble the back cover, either using fastboot oem edl or from a device off, pressing both volume buttons at the same time that you connect to the PC, firstly open Windows device manager and check that it is listed as Qualcomm 9008-USB, you need to install this https://www.getdroidtips.com/download-qualcomm-qdloader-hs-usb-driver/
Rom should be unzipped on desktop. Not inside a faulder.... If you unzipped it inside faulder error will come up

The folder can be placed in any side, even I always have my tool installed in the main drive (C) and the Miui ROM in another partition (D) you have to suppress all the spaces in the names and lastly browse where the images' directory is, not inside but where it is the images directory and the scripts.
What about EDL, did you achieve to get it? Upload some screenshot, from the browser files and from the error you are getting, I'm sure it's easy to fix it, maybe you are missing something.

Don't use "Clean all & Lock" at least till you solve it.
EDL method is simple to use if you have your bootloader unlocked (this is one of the reasons why you don't have to lock it right now).
To use the EDL method you just have to power off completely, then while you connect the device to the PC press both volume buttons.
Before install the Qualcomm 9008 USB drivers.
