Thanks in advance for your help.

Make sure you have enabled "allow OEM unlocking" in developer settings. After that go to bootloader and enter the following commands (this will wipe user data)
fastboot oem unlock-go
After entering this command your phone will factory reset.
Now come back to recovery and flash twrp.
fastboot flash recovery twrp.img
fastboot boot twrp.img

Tried that also, but in the command window after executing the command, it says "waiting for devices" and nothing happens after that. OEM unlocking is already allowed in setting.....I also tried by using toolkit available on internet, but in that, my devices is not detected. Tried Kingo Root, but phone get restart every-time when it goes to 90%.

which os do you have?

Revert Asus Zenfone 3 Max ZC520TL to previous firmware

I would like to revert the firmware on an Asus Zenfone 3 Max (ZC520TL) to a previous one (13.1.4.43).
With the current firmware (13.1.4.69) I have PIN and fingerprint issues.
-I tried to go back to 13.1.4.43 using Asus Flash Tool but it does not allow going back.
-I tried to go back thru the Recovery but I got a security error …does not allow to go back
-I try using ADB but it does not show when sending command "adb devices" even though I installed drivers (ADB, MPT, etc.) and it does shows in the Control Panel when the phone is ON.
Also sent the command "adb reboot bootloader" the phone reboots into bootloader/fastboot mode but still does not allow to go back to previews firmware.

What exactly is the security error you get when you try to flash that firmware in recovery? You tried flashing this file (US version) from the Asus website through stock recovery? You should be able to do it through recovery, but you may need to edit the updater-script file as mentioned here in part 1, steps 2-4.
EDIT: Looks like you won't be able to use fastboot to flash images unless your bootloader is unlocked. Is yours?

Xiaomi mi A1 cannot boot images, recovery etc from fastboot.

Hello!
I have been trying to boot from boot.img/recovery.img with "fastboot boot" command but it doesn't work, so I can't root my phone with magisk.
I have to use "fastboot flash" to root it, and that way I lose the option to do OTA updates.
The issue:
1. I connect the phone to the computer in fastboot mode.
2. I use "fastboot boot patched_boot.img or twrp.img"
3. Phone goes into charging mode.
Things I've tried:
- Different cables
- Different computers
- Latest platform-tools
- Flashed stock ROM from fastboot
I am currently on Android Pie but I have this issue since around June 2018.

Reboot to EDL mode from FASTBOOT!

Reboot to EDL mode from FASTBOOT!
No more Test Point Method needed
Technical Details:
Redmi Note 3 support rebooting to EDL in Android Bootloader aboot module (the "reboot-edl" command) but fastboot utility doesn't recognize "reboot-edl" in the command line and refuses to sent the command to the device. Since FastBoot command protocol is simple and text-based, it is enough to send a packet containing "reboot-edl" text over USB. The simplest way to do that is to patch Windows fastboot.exe file, replacing "reboot-bootloader" text with "reboot-edl". As "reboot-bootloader" string is found in the command line, fastboot.exe sends the same constant string to the device. So if "reboot-bootloader" is replaced with "reboot-edl", you can specify "reboot-edl" in the command line and the same text will be sent to the device.
New Update: Fastboot updated to latest version.
Tutorial:
1. Download the Fastboot_to_EDL from : https://www.mediafire.com/file/yr7csyo64e97vbu/Fastboot_to_EDL.zip/file
2. Extract the zip in your desktop
3. Open the folder and double Click on Reboot.bat

4. Reboot your device to Fastboot Mode by pressing
Vol Down + Power button and connect your device with PC and Press Enter.
5. Your Device will be rebooted to EDL!
6. Now flash your Fastboot Rom with Mi Flash Tool to Unbrick your Mi Note 3.

Totally bricked Huawei PRA-LX1

I'm struggling with this phone for couple of months, trying to fix it from time to time. Now I feel like there's no hope for it anymore. Tried flashing a lot of custom recoveries for this phone with no success - after turning on the phone and after the Huawei logo I just see fastboot-similar screen with a title 'Error Mode' and with errors: Func NO: 11 (recovery image) and Error NO: 2 (load failed).
I tried TWRP, Elite TWRP and nothing, always stuck at Error mode. I believe this phone is bootaloader and FRP unlocked (you can see in fastboot). I tried extracting recovery, system images from firmware but recovery_ramdisk spits out 'FAILED (remote: partition length get error)' and also I'm not really sure which image should I extract from the update.app.
I'm attaching 3 images - error mode, fastboot mode, images list from the extractor. If anyone has some ideas, I'm happy to hear them.

Are you sure your phone is running EMUI 8?
In fastboot mode run commands:
fastboot oem get-build-number
fastboot oem get-product-model
fastboot getvar vendorcountry
fastboot oem oeminforead-CUSTOM_VERSION
fastboot oem oeminforead-SYSTEM_VERSION
and post the results.
