fastboot Unlock device failed - OnePlus 2 Q&A, Help & Troubleshooting

I wanted to root my Oneplus 2. I used the Oneplus 2 Toolkit.
The OnePlus 2 will no longer boot. It briefly shows the OnePlus logo, then it reboots and displays the OnePlus logo and reboots and so on....
I can not start in recovery mode, because then comes the same result.
It is only possible to start the OnePlus 2 in fastboot mode, but I can not install TWRP recovery because the device locked.

Search into the developer section, you will find the stock recovery, system, data and all the other stock partitions in fastboot format with the appropriate complete script for a factory restore. You should be able to flash them and recover your phone.

OnePlus 2 stuck on logo

ok, so, I tried to root my oneplus two, it failed and got into the loop where it says the apps are optimizing, then I disabled "allow bootloader"(so I can't flash anything) and it just stays either on the oneplus logo or in fastboot mode( it is detected by the pc in fastboot not adb), any solutions?
Search for oneplus two Qualcomm restore option.

my Redmi 3S is bricked?

I unlocked the BL and flashed an International Developer MIUI two years ago, and it has been working fine.
I want to flash a stable ROM now. the miui website gives three approaches (system update, recovery update, fastboot update).
I first tried system update, but the system cannot proceed.
then for recovery update, volume up + power button enters Teamwin (TWRP), not the recovery interface shown in the official guide.
then fastboot update, unfortunately the MIFlash tool does not recognize the phone in fastboot mode.
so I went back to TWRP, clicked Install, and installed this ROM: http://bigota.d.miui.com/V9.2.1.0.MALCNEK/miui_HM3S_V9.2.1.0.MALCNEK_fe706c31c4_6.0.zip
which I saved to the phone storage earlier.
now the phone is in a bootloop , stuck at "mi" boot screen. somehow I can still enter fastboot mode, but I don't know what I can do to save it.
please help me , thanks
Trying to make guide for that
I just resently came out from hard bricked

Device Boot Looping/Soft Brick

I decided to unlock the bootloader so that i could flash TWRP recovery but after unlocking the bootloader on my device, it has been stuck on the logo screen with "powered by android" under it. I have tried using fastboot to clear userdata & cache but that just leads to my phone again being stuck on the logo screen. The device also can't boot into recovery. When I chose to power off in fastboot it causes me to be stuck on the logo screen. Any help is appreciated I am on android oreo btw
Did you try a back to stock zip? go to fastboot and run flash-all.bat, while your device is plugged in ofcourse.

Let me guess.
You unlocked the boot loader and flashed TWRP and now you are looping, right?
There is no compatible TWRP that is compatible with Oreo on this phone.
You cannot leave TWRP installed. You can only install it along enough to get the recovery to boot.
You then must flash the stock boot image.
I had this problem tonight also. In my case I suspect it had to do with the install of magisk in which I checked both boxes and patched the bootloader. on reboot I was stuck on boot. Just wanted to add my solution. I got the pie back to stock zip here https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681 then I put it into the adb folder and ran the flashall.bat script. I tried the no wipe one and it saved my information. very happy I didnt have to resetup my phone in the end.
did you remember to flash a stock boot.img before flashing magisk (to clear TWRP?)

Stuck at Asus logo during boot

So I was installing magisk with the help of twrp, but I was having a difficult time finding the magisk zip in twrp. Had rebooted the device and booted to fastboot and recovery mode for around for more than 30 times. Now, this is the situation of my device: its right now switched off. I can enter the twrp, i can access the fastboot mode but if I try to normally switch it on, the boot is stuck at the Asus logo. Nothing happens after it. From the Asus logo, i am able to swtich it off and move to fastboot and twrp. Help me please.
Maybe flash decrypt zip ?
Try this. go back to twrp, abd instead of reboot phone, press power off. then press power on button manually. Works everytime for me

asus zenfone max m1 recovery, rom not working. help

Please HELP
I am writing here the whole story.
I unlocked the bootloader of my Asus zenfone max m1 (3/32GB) using the unlock tool which I downloaded from Asus's website.
Then, I went to fastboot mode and flashed TWRP recovery and then tried booting into it through the cmd screen using fastboot boot twrp.img command and it worked.
Then I followed a really good tutorial and flashed the pie firmware, Pixel Experience and magisk and ZIPs in order.
And it showed no error, everything was fine and then I clicked on the reboot system button, it rebooted the system but the phone was stuck at the google logo with a loading bar and didn't go beyond that even when left for 30 mins and I tried rebooting the phone multiple times and that did not help. the phone was stuck at the google logo every time.
Then I turned off the phone and tried going to TWRP to flash the pixel rom again but the phone only went into fastboot mode, it never booted into recovery even though I tried multiple times(I was trying to boot into the recovery through the volume and power buttons, not through fastboot mode).
I flashed the phone's recovery multiple times and also the boot image (I even tried flashing the stock recovery) but the problem is that everything goes fine in the terminal, it shows that it flashed the img file successfully and it is finished but the commands like fastboot reboot recovery don't work at all, they all just reboot the phone normally and the phone just shows the ASUS logo for few secs and then turns off.
Note: I used fastboot erase commands to remove the pixel experience rom and now I'm only left with a phone which boots only into fastboot with no rom and I don't know about the recovery because it shows that it flashed but it never opens.
Hi
I am having a similar problem in that I can oly get into recovery mode with adb reboot recovery. I researched and tried all possibilities with the phone key but I can only go into bootloader mode.
After flashing recovery successfully (?) I can only boot the phone normally and that seems to reinstall the default recovery manager.
While researching I found that there are some discrepancies with the ID out there. While my phone is a Zenfone Max (M1) with the ID X00PD some places (TWRP) confirm that but others refer to Z555KL.
Did you get any further?
