My friend just sent me a soft brick DT2. It was bricked because he downgraded from Nougat to Marshmallow. I've tried flashing it using RSD Lite and minimal adb command still resulted in failed. It won't boot to normal. Stuck always in fastboot screen. Any ideas to get it fixed? Any helps will be much appreciated. Thanks in advance.
You can not flash Marshmallow without unlocked bootloader, try to flash stock Nougat again.

I'm currently on lollipop stock firmware with phone rooted and bootloader unlocked. I have also flashed latest Twrp recovey.
But here is the problem, i downloaded Resurrection remix latest version and tried to flash it, but error 7 came up. I bypassed this error by editing the updater script ( i followed a tutorial ). Now when i flashed the rom it says its sucessful but when I select boot to system it goes to fastboot mode. Im a noob so please dont be harsh to me.
PLEASE HELP ME FAST
THANKS
You still need to upgrade to stock MM before flashing RR M.

No, but to be sure go to fastboot the type:
fastboot oem device-info
if you see this -->> (bootloader)Device unlocked: true
then you are still unlocked.

Thanks man it worked and i am able to flash Resurection remix.
Thanks a lot again
Glad I was able to help. Warning, flashing can be addictive! And make sure to have a nandroid back-up.
WRT the original post, I tried the same procedure but after having errors i flashed the twrp with adb through cmd:fastboot flash boot boot.img . And now it is showing no OS available and shows that it is not rooted in the twrp recovery. Now it is still not flashing the rom and showing error and now i have no idea what to do. So, please give me instructions on how to repair my asus zenfone 2 laser ze550kl. I did all this on MM.
If you have TWRP 3025 then you can flash any custom ROM. Try to redownload the ROM, maybe it's just a bad download. What error did you see?

Flashing stock rom has nothing to do with locked/unlocked bootloader, do you get any errors or what happens while flashing ?
Why it happened ?
Are you trying to flash latest update september's one? If not then try with it (see guide section for steps, download and more info)
Hello mates!
Yesterday I accidentally bricked my phone and I spent ours and ours on this and others forums to find solution but without succes, so here is what was happen:
I was on L21C432B380 firmware, stock, bootloader locked, without root acces. So I tried to flash ROM 7.1.2 AOSP by Meticulus. I followed step by step guide. I succesfully unlocked bootloader using fastboot. Then I flashed TWRP again using fastboot so I can downgrade to EMUI 4.X and that was succesfull also. After that I flashed oem-info using TWRP and flashed stock UPDATE.ZIP using three button method, both succesfully but when phone tried to boots up It shows message "No OS installed".
My entire system and data was deleted, there is no recovery, bootloader is again locked, I have only managed to get into fastboot mode using adb
Every single command I tryed to run in cmd results in this message: "FAILED (remote: Command not allowed)
Somehow I need to install Firmware using fastboot but don't know how cause bootloader is again locked
My knowledge about this things is above average but I cannot "google" the problem
Please help and thanks in adavnce

Hello man,
Dont know why u do that (downgrade to MM)...
Explicitly written for flash AOSP 7.1.2 to be on emui5 (were u was)...
Flashing oem also relocked your bootloader (written ton of times in threads)....
Now using fastboot re-unlock bootloader re-flash TWRP.
If u maked a full backup just use it, otherwise try to follow this guide..

Hope u will resolve.

Has anyone successfully relocked the bootloader on a A2017G? I've tried flashing various versions of Nougat and now with the new official Oreo and every time I try booting to bootloader (fastboot) the phone just boots into system. I'm on full stock system with stock recovery. I flashed a B12 EDL from LOS 15.1 to then update to the new Oreo.
Everything else works fine, the drivers are correct I simply just cannot access the bootloader, no matter which rom I flash.
Hi, on A2017G I succeeded with Axon 7 toolkit, option "bootloader lock"

Problem solved, I've managed to lock the bootloader.

I flashed a fastboot EDL unlock that I found here on XDA and then I managed to lock the bootloader with OEM lock. However, I bricked my phone and couldn't boot into OS but it wasn't a big issue since I just flashed a B12 EDL afterwards and from there got an OTA update to Oreo with the bootloader locked.
I came back from LOS 16.0. Flashed A2017G_B10_NOUGAT_FULL_EDL in EDL but there's a warning that my bootloader is locked. I wanted to relock it but the warning prevents me from entering bootloader or fastboot (or maybe they are not even present....). Next I flashed A2017U_FASTBOOT_UNLOCK_EDL in MiFlash but it did not do anything. It flashed OK but I still cannot access fastboot. Should I flash some marshmallow rom? Thanks in advance.
I have the same problem. Cannot enter fastboot mode on Nougat ROM.
Ok I found the way usin Axon 7 Toolkit
1. Set the Android version to 7 using option 13
2. Perform unlock bootloader
Following instruction Axon & Tookit gives you EDL image of the proper fastboot partition giving the possibility to enter fastboot mode
then fasboot oem lock
I wanted to say thanks that works, but apparently my phone is bricked now - it hangs on green ZTE logo. PC recognizes it as DFU. Cannot enter EDL either. I guess I look for some guide how to recover from this situation
Managed to fix that. Somehow I was able to enter fastboot. It said my bootloader was locked so i flashed TWRP and from TWRP using ADB installed stock Nougat rom

If you was able flash twrp mens your boolaeder was unlocked?
No there's a TWRP that works on locked bootloader.

Seems that TWRP was inatlled before the bootloder was locked again.
