****************************************************************************************************
i suggest you this guide this method do for me

Disable update CM recovery option in developer options... Then flash custom recovery.... it will work.

once flashing twrp recovery, you will need to use
Code:
fastboot -i 0x1ebf reboot
command.

remove battery after install recovery before restarting phone
then insert battery and start in custom recovery

install Custom Recovery
1) enable developer options
2)enable advance reboot and usb debugging
3)disable Update CM recovery option
4)reboot to bootloader and flash recovery
" fastboot -i 0x1ebf flash recovery recovery_twrpyulolli.img "
5) directly disconnect phone (phone displaying FASTBOOT MODE)
6) remove battery and start phone in recovery mode using volume UP+DOWN and power key
7) And YOUR are IN TWRP RECOVERY ......
THIS method work for me perfectly .....i m also having same problem of flashing custom recovery and again showing CM RECOVERY

What kind of recovery are you using? If you are using stock recovery. Just use add sideload. If you are using TWRP. Then go to fastboot and flash the stock recovery. You can find the stock recovery in the rom downloaded from Asus : https://www.asus.com/Phone/ZenFone_5_A500CG/HelpDesk_Download/. Version 2.22.40.540 is recommended

like this! ----((Type fastboot devices and hit Enter. Your device should appear.
13. Type fastboot flash fastboot droidboot.img (be very careful in writting this line). Hit Enter. Wait till it's done.
14. Type fastboot flash recovery recovery.img and hit Enter. Wait till it's done.
15. Type fastboot flash boot boot.img and hitEnter.))
I don't find those files (and files like system.img) in the zenfone 2 laser rom zip(UL-ASUS_Z00E-WW-13.10.7.1-user.zip) but only Boot.img ,system.new.dat... nothing useful.
I dowloaded a official recovery and twrp, i tried to flash the recovery.img and the boot.img and i try to reboot in bootloader mode but nothing, than i tried to flash the trwp.img but the process failed!
I've a Raw file image of the rom but i don't know if it possible to install it in fastboot and what is the right Command on fastboot!
This is all, i hope that someone can help me

Download stock recovery from here and flash with fastboot flash recovery name_of_recovery.img and download official firmware from official site.
Go in to recovery and wipe cache and data,after select update from adb,open adb and write this command:adb sideload name_of_firmware.zip or put firmware.zip in to sd and rename update.zip go in to recovery wipe cache and data and select update from sdcard and select update.zip

thank you for the response, after the flash of the original recovery, i tried to go in recovery with "volume - and power botton" but nothing only asus image, than i tried with fastboot command --->"fastboot boot recovery.img" and Failed( remote dtb not found)

nothing! My friend doesn't remember if he unlocked the bootloader, the phone doesn't go in recovery... So the problem is the unlocked bootloader or a locked bootloader?!
from your answer I understand that if it is unlocked i can go in recovery, so i assume that the bootloader it's locked and for this i can't go in recovery...

[Help][A2017G] SoftBrick only bootloader and stock recovery

Hi,
I have an A2017G which after trying linageos had the stock rom from here https://forum.xda-developers.com/axon-7/development/rom-guide-updates-to-stock-files-via-t3469484 TWRP and an unlocked bootloader. That worked ok, and I wanted to upgrade to the stock ROM 7.1. I installed this using TWRP https://forum.xda-developers.com/showpost.php?p=71664539&postcount=29. But now when it boot's after the bootloader it's stuck showing a linux logo, and it won't boot Android.
In the bootloader (http://i.imgur.com/Os4vkwT.jpg) I can try to go to fastboot, but selecting that only reboots the phone. I can however select recovery and go to the stock recovery (http://i.imgur.com/PBj6y6X.jpg). From there I have tried to sideload (selecting Apply update from ADB and adb sideload rom.zip) the stock rom (http://www.ztedevice.com/support/detail?id=1170789A90BA42E18B3364B80C7F5A26), the previous rom I tried to install (https://forum.xda-developers.com/showpost.php?p=71664539&postcount=29) and another TWRP stock rom (https://forum.xda-developers.com/axon-7/development/rom-kernel-stock-7-1-1-b02-based-a2017g-t3592470) but all fail at the very beginning saying "(adbd status 1) Installation aborted" (http://i.imgur.com/RzNSBtu.jpg).
I also tried to install linageos back using sideload but it fails ("failed to verify whole-file signature"). I believe that is because it's not the official rom and the stock recovery only accepts that.
ADB only works in sideload mode and fastboot doesn't (it loads the bootloader again).
Do you know how I should proceed? How could I install the stock rom, or TWRP again?
Thanks in advance.

Try it with this guide:
https://forum.xda-developers.com/axon-7/how-to/guide-reinstall-twrp-root-update-to-t3578552
If you can't flash recovery with axon7toolkit try it with the last step "Get Fastboot" first. ZTE removed the fastboot mode in Nougat, so you have to flash another fastboot image.
If you can boot into fastboot again you can flash TWRP and from TWRP a rom.
Good luck!

Hi Darkem,
Thanks a lot, that actually worked. I was under the impression I wouldn't be able to install TWRP because I was only able to use the command "adb sideload update.zip" but other commands like "adb reboot edl" didn't work. But as it's said in the other post, pushing the three buttons of the phone set the phone into EDL mode. From there I was able to install TWRP.
Thanks a lot again

(A2017G) Hello. I no longer have access to fastboot because I flash a stock rom (Nougat) with the recovery stock and it has removed my modified bootloader, I managed to install twrp in edl mode but I still have no access to bootloader. What should I do please? Flash a stock rom (Marshmallow) here (https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547) to gain access to fastboot again (bootloader )? Thank you.

Granted I have the A2017U, but in stock recovery I can still access the phone memory with my pc. Why not download the stock rom from ZTE, put it on the phone memory, and flash it in the stock recovery?

Sorry, why do you want fastboot? If you're planning to relock the bootloader you'll need to be fully stock, which wouldn't be the case if you just installed a fastboot zip. Relocking the bootloader is probably the only thing that fastboot is mandatory for

How to flash a custom rom in stock pie as base. tUtORIAL

How to flash a custom rom in stock pie as base,using adb sideload
The twrp still does not work well in android 9 just the adb sideload function in twrp's advanced options.
First make sure you have the bootloader unlocked.
Second put all the files need in adb past rom kernel magisk etc...
1-put the mobile phone in fastboot mode
2-Boot twrp through adb using the command bellow
fastboot boot TWRP-3.2.3-jasmine-20181201.img
donwload twrp https://t.me/XiaomiMiA1ClouD/810
3- Make format data and make all wipes in the 2 slots
4-now go twrp advanced option and turn on adb sideload
5-for example for flash last pixel rom gapps included you use this adb comand
adb sideload PixelExperience_jasmine-9.0-20181219-0813-OFFICIAL.zip
6-reboot to bootloader and boot twrp again
7- check slots in twrp if on a change to b
8- reboot to sys done !!!
note:
9- you can flash magisk using same method
adb sideload magisk.zip

I will update the post for How to update a custom ROM after an update.

"3- Make format data and make all wipes in the 2 slots"
What u mean by that 2 slots? should I have to go to twrp and format & wipe A partition then change to B then format & wipe? after 2 slots/2partitions again back to A then adb sideload on?

After installing the gapps Or after booting once to rom and then back to twrp

When flashing magisk and hex by adb method, next we change slot like flashing the rom?
Flash magisk/hex/gapps by adb
Changing slot
Reboot
Like that?

Is it possible to install twrp if my phone is on Android 9 ?
If yes how to do it?
Thanks in avance
