Hello I'm trying to flash stock ROM via adb, specifically cust.img, boot.img, system.img, Because I've bricked my phone and it stuck on huawei logo, but when i try to flash, i got the following error "FAILED (remote: Command not allowed)"

Please how I can unbrick my phone and reinstall the firmware
Obs. My bootloader is unlocked and I'm using TWRP recovery
Is your phone really shows Unlocked in red color when it's in fastboot mode?
Was your phone rooted, if yes, with which method?
You should try doing:
fastboot erase cache
fastboot erase userdata
These commands perform the same thing as Factory Reset do.
If it's not working, try to do the "dload" method with your original firmware your phone was shipped with.
Create a folder, called "dload" in your sdcard root, put the UPDATE.APP file of the firmware in it, and without connecting it to PC, press Vol + and Vol - and Power button until it starts flashing the firmware, and see what happens.
In later days, we've got a lot of troubleshooting topic opened up with your problem, the users cannot flash even with unlocked bootloader, and yet, there's no real solution to them.
I suggest that you use Windows 10? If I'm right sometimes this version of Windows cannot be used to flash via adb
I recommend you to use Windows 8.1 or 7 . My best way is of course using Linux

Yes, it shows PHONE unlocked in red name, and I've made the root using an app called kingroot
I've tried to erase cache and userdata using adb but I can't, still got the same error "FAILED (remote: Command not allowed)"
I can't make dload method because I don't have stock recovery, and I can't flash the stock recovery using adb because its keep saying "FAILED (remote: Command not allowed)".
I don't know what to do

I'm using windows 7 is this moment, maybe I try to flash using Linux later
Seems like all the guys with the same problem used KingRoot to root...that is the common thing amongst all.
I dont't think you need the stock recovery to update via the "dload" method, but I'm not sure.
If you don't have your original firmware's UPDATE.APP yet, download it, as well as the Huawei Update Extractor.
Load your file into the program, select ONLY BOOT.IMG, CUST.IMG(if it has one), SYSTEM.IMG and RECOVERY.IMG(optional, if selected, restores original recovery) right click on one, and press Create Flashable Zip.
Copy this to your sdcard and try to flash it.
I did not thest this above method, and don't know it the created flashable zip is really flashable, but I'm running out of possible solutions slowly.
Let us know what happens.

So I tried to create a flashable zip using the Huawei Update Extractor however, was not possible, it's showing the following message "no suitable files selected. Check profiles.xml"
I've tried also creating flashable zip manually and flash it using TWRP, but TWRP reboot every time I try to flash theses files, that's why I think dload method work only with stock recovery
Hello,
I created the script for flash via fastboot if you want try this method
Extract BOOT.img, Cust.img, Recovery.img, System.img and copy to fastboot folder.(attachment)
Enable developer options and USB debugging
Simply run file FLASH-ALL.bat file

Same issue with Huawei G6-U10
I'm having the same problem with Huawei Ascend G6-U10
Currently running on ROM b146, since it has some issues I was trying to downgrade or upgrade ( there is a b330 out).
I'm not an expert.
This morning I've unlocked the boot loader and then tried to flash a couple of different ROMs and I always get the same error message:
c:\adb>fastboot flash BOOT ./G6-U10verb330/boot.img
target reported max download size of 536870912 bytes

I'm guessing this is not a G6-U10 specific issue so if anyone can give any hint it'll be very appreciated.
Thanks.
I have the same problem with a honor 4x.
Rooted with kingroot. We haven't writing permission in /system. That's why we can't install the recovery. If you try to install superSU and update the binary I guess you get an error.
Now the question is: how we can do to make writeble /system with fast boot?
"mount -o rw,remount -t ext3 /dev/block/xxxxxxxxx /system" in terminal doesn't work...
Similar thing happened to me. Even if command for showing unlocked bootloader said it was unlocked that was false because I used Kingroot previously. Only thing that helped was to unlock the bootloader through fastboot again. Then it was really unlocked and I could flash recovery (in my case TWRP) which before I was unable to.

Have you tried it with linux yet?
And have you used the Update.APP and dload method?
Maybe a driver problem? Have administrator rights? And debug mode on?
Try to connect your phone (power on) to the pc and wait to be recognized. In cmd type this:
Code:
adb devices
It has to show you your serial number right? If doesn't your device is not being recognized by adb.
Next type:
Code:
adb reboot-bootloader
This will restart your phone into fastboot and now you can type "fastboot devices" like first command and it has to show you your serial number again.
Try rebooting into bl with this, not by plugin in the phone, and install the rom again

Hello I have a problem with my phone. I do not know how to hell I fix it.
It says error cannot load system.img but still I can install boot.img and others.
I¨d tryed that "dload" with update.app doesnt work.
phone is Huawei P8 Lite
this is my first time here
Have you tried install it in twrp? You don't have a twrp backup of stock rom?
In this case if you go in the Huawei eRecovery you can restore stock rom and twrp will be overwrited downloading the last rom , i tried it with my p8 lite 2017 .

What are you using to go into fastboot mode? Is it ADB from Android SDK?? It turns out that using ADB from Android SDK lets you flash small files but not large files... I suggest you try flashing the file through Minimal ADB & Fastboot

This happens when you flash wrong version. You must be using the twrp for KK, while MIUI is LP.

Extract "boot.img" from the root of MIUI rom zip and flash that with "fastboot flash boot boot.img"
Then flash the twrp for lollipop
Otherwise, you'll need to flash the firmware through QFIL Downloader

It seems you successfully flashed the twrp recovery...............
If your recovery is right i.e.according to your previous os
Then just u need to enter into recovery by pressing 3 buttons at the same time....
if not worked then flash another twrp version....

Today I was trying to install a newer rom (MIUI 8.1)(also MIUI 4.11 after the 8.1 failed a couple times) through twrp 3.1.1.0-aries and my mi2s got soft bricked after the update failed with error code 7 something about being unable to write system to /system.

Then I tried to flash it using Mi PC Suite which got stuck at 52% for 2 hours at "sending system.img". I saw it wasn't going anywhere so I disconnected the device and terminated the task.
At that point the phone didn't go into the recovery mode anymore. I think Mi PC Suite might have done something to the partition table.
Right now the phone is stuck in fastboot loop and can't go into recovery mode unless I run the command
Code:
fastboot boot twrp.img
which can sometimes fail as well with error:
Code:
FAILED (status read failed (Too many links))
At the first time I managed to get back into twrp using the above command I felt some relief and I tried doing a factory reset from the twrp menu. It didn't help.
Flashing twrp using the command
Code:
fastboot flash recovery twrp.img
says everything is okay and is finishing without errors but I still can't boot into it. It just goes straight to fastboot.

I fixed this by downloading "aries_images_4.11.21_4.1_cn" and editing the "flash_all.bat" script to include
Code:
fastboot %* flash partition "%~dp0images\gpt_both0.bin" || @echo "Flash partition error" && exit /B 1
in the third row right after the 2 "soc-id" checks.
I am still not sure how to upgrade from here to one of the newer miui roms.

Solved. I managed to flash aries_global_images_V8.1.3.0.LXAMIDI_20161122.0000.00_5.0_global using MiFlash.
At first I thought it didn't work because it flashed the whole rom way too quickly in like 5-10 seconds and booted back to fastboot but then I just left the device there to rest and when I came back after a few minutes I saw it booted to a black screen with a white MI at the center of it and then android and 3 dots appeared at the bottom so I just waited for a few more minutes and it installed everything.
I hope this might help someone else with similar issue.
I was on MIUI Global 12.0.2 Stable. I tried to flash Pig's latest Lineage (2020.07.21) from TWRP. The flash failed with an "Error 7". When I tried to reboot, the device went to "fastboot" mode.
After that, every attempt of a reboot ended in fastboot mode. So I tried to flash TWRP.img. Flashing went OK. But "fastboot boot twrp.img" gave the error "FAILED (remote: Failed to load/authenticate boot image: Load Error)". The result was same with "fastboot oem reboot-recovery" command.
So I was stuck in fastboot mode with the risk of battery depletion. Below is the commands I ran to flash the TWRP.

SOLUTION: One needs to flash the fastboot ROM in MiFlash.
My situation had an extra issue as there were no fastboot ROM for MIUI Global 12.0.2. So, I downloaded MIUI 11.0.5 Global Fastboot ROM and flashed it. One needs to keep in mind about the "Anti-Rollback Protection" (https://www.xda-developers.com/xiaomi-anti-rollback-protection-brick-phone/) and take necessary steps to avoid an anti-rollback brick.
If anti-rollback compatible ROM not available, then just delete first lines in all .bat files (.bat for Windows; .sh for Linux) up to the first line that starts with "fastboot %* getvar product..." of the available fastboot ROM. Those lines are the anti-rollback check. After than you can flash it via MiFlash.

Thanks for the reply. I tried that command too, but ended with the same error.
Now, downloading the 11.0.5 Global Fastboot ROM since no 12.0.2 Fastboot available. My plan is to just delete first lines in .bat files of the ROM to avoid 'rollback protection' and flash via MiFlash before the battery goes zero. According to google, it seems flashing the full Fastboot ROM is the only solution
SOLVED
Solved. Edited the OP.

Wow, thank you so much for pointing this out!
I just had a close to two hour journey through all emotions after trying to restart my phone and suddenly ending up in a seemingly inescapable fastboot hell...
I've tried booting different recoveries, all failing with
Code:
FAILED (remote: Failed to load/authenticate boot image: Load Error)
and was already at the point of giving up getting my system back, just trying to save my data if possible. Flashing seemed to work, but
Code:
fastboot reboot recovery
just threw me back into fastboot, which I assumed to be due to the phone rejecting the flashed recoveries just as it was rejecting them when I tried to boot them directly.
When I saw this comment I wondered whether Xiaomi implemented rebooting directly to the recovery differently (as it turns out, it doesn't seem to be standardized) and
Code:
fastboot oem reboot-recovery
worked perfectly! After reflashing my ROM from TWRP I was booted back up into my system with everything intact, as if nothing has happened.
