Messed bootloader unlock - ZenFone 2 Q&A, Help & Troubleshooting

I've tried unlocking bootloader using official Unlock app from Asus
I've the latest firmware 2.20.40.168 unrooted.
I've tried it thrice, all I see is is a black screen with a USB symbol and full white bar below it.
I can't enter the bootloader itself.
I've tried reflashing droidboot.img, boot.img and recovery.img. All says <waiting for device> infinitely.
"fastboot devices" displays nothing, my deivce is not detected!
Yet, I can enter the OS and use it flawlessly!!
Please help me enter the recovery please!
I've attahched the screenshot of the black screen when I press Power+Vol Up (release power up upon vibrate)
Thanks in advance!!!

I cant reach the bootloader, how do I flash a custom recovery? Sorry, I'm no genius...pls guide me with a link!
Thanks in advance

Your phone is bricked! Search for unbricking with xfstk in the zenfone 2 threads. Your phone should be recognized as Moorefield when connected to a PC.
Your other option is to go to a Asus service center or send it to them, but your warranty could be void, because of using official bootloader unlocker!

You said it too fast. He's able to boot to system properly but unable to enter bootloader.
Sent from my ASUS_Z00AD

@krasCGQ
Yeah, you're right! Too fast to say bricked!
But afaik xfstk is the only way to get droidboot/fastboot back.
As far as the phone wouldn't be recognized as any other than Moorefield.
Even if adb can recognize the device, one could not flash droidboot with that, right?
... Or perhaps I'm just talking bullsh*... I'll better quit now... [emoji32]

I'd say bricked too, even though you can run the OS when a new update comes out it won't update if it can't go to recovery. In fact it might just start a bootloop...
If it bricked while using the "Official tool" then I'd return under warranty, it was working fine before... As has been said, the IMEI number was registered with ASUS when unlocked, I just wouldn't wait too long as the longer you wait the less chance of being fixed under warranty.
At the very least you can ask about it and see if you can get it sent back for warranty fix, just don't say anything about flashing anything but bootloader...

unable to install or launch TWRP

Hey,
I've unlocked my Mi 6 today (i'm using the global developer ROM 8.9.13 (MIUI10)) and wanted to root it, as many guides said I have to replace the default recovery with something like TWRP
result was:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
after leaving it like that for 30 minutes nothing has changed, the screen on my mobile was the the default fastboot screen nothing ever changed
so i tried to just launch TWRP without installing it:
nothing changed like before and i've stopped after 5minutes
i also have the same result with RedWolf Recovery Project:
I also tried using XiaoMiTool but all i got was the message that my phone is not connected to my MiAccount and still locked and did nothing
Does anyone have any idea whats going?
Edit:
seems like flashboot commands dont work? tried flashboot continue to reboot the device after checking with fastboot devices to see if it was recognized by the system and it was indeed.
and the result were the same as above cmd was stuck mobile didnt react....
Thanks

I'd rather flash the recovery than just booting to it. You can flash it with fastboot flash recovery recovery.img
You should be able to boot to recovery afterwards. Or at least that's what I did when I bought my phone. I updated to the latest version of MIUI (android 8.0), then I enabled "oem unlock") and I was able to flash twrp with no problems. Keep in mind that the stock rom erases any custom recovery with the default one on boot.
Facing the same issue. Tried everything but no success.

you will have to flash stock and try again, please remeber to unlock bootloader and turn on usb debugging.
Turn the phone off (in case you cant, holding vol- and power will hard reset the device)
as soon as the screen goes black press and hold the vol+ and vol- keys in and connect the usb cable, this should kick it to download mode for you to flash stock image.
Thanks it worked and took me to download mode but unable to flash the ROM, trying to flash 10 but shows something in download menu, screenshot attached.
Giving the error i am facing, trying to flash stock rom via odin but it gets stuck at boot and nothing happens.
I am able to get into download now but seems like bootlader is off it is giving an error
error - SW REV. CHECK FAIL (BOOTLOADER) DEVICE:4 BINARY:2
sorry for back to back posts.
download from here; https://www.sammobile.com/samsung/galaxy-a50/firmware/#SM-A505FN
select your phone model tho, if not FN.
"SW REV CK FAIL usually means that you are not flashing the most current released firmware version. Most Samsung devices will not let you downgrade. You have to flash what was previously installed or higher Android version. "
from; https://androidforums.com/threads/error-odin-sw-rev-check-fail-device-4-binary-3.1251721/
So maybe try pie again then upgrade to 10?
Is your odin the latest, I've found that not all odins work with all phones.
For samsung A50 they say this one; https://dl2018.sammobile.com/Odin3-v3.14.4.zip
can you reboot to stock recovery? by holding vol+ and Power?
Try factory reset and wipe everything.
Have tried to flash the one was installed in mobile earlier but still giving same error, it was ATB6 installed.
Sorry I couldnt help more, there seem to be plenty of youtube videos out there tho; https://www.google.com/search?q=SW+...3TxUIHU4_C3QQ_AUoAXoECAsQAw&biw=2560&bih=1344

Did I Brick my 2XL?

After a bunch of research I finally decided to take the plunge to try and move to Lineage OS.
Phone is a Google unlocked 128GB 2 XL.
I was able to get through the unlock portion but after that all the guides went different directions. I was following the process from TWRP and at one point had the TWRP recovery app showing via fastboot but now all I get is the "device is corrupt" warning which then ends up in the white screen with Google logo and small unlocked icon.
Any chance I can get back to scratch or press forward to LineageOS/other ROM or is this thing a brick?
*Update* Not sure what key combination I used but I can get to the following TWRP screen. However the touchscreen does not respond and after the screen hibernates any key returns it to this state:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

Download the last Google ROM image, enter the bootloader, and install it using the flash-all batch file included in the zip file. That will get you back to factory so you can proceed.

Not sure how I can do that.
I can get to the default green START option. If I selection that the system boot to a white screen adn stops.
If I select BOOTLOADER the device pops back to the green START.
If I select RECOVERY it gets to the TWRP screen but the touchscreen nor buttons work.
I've tried connecting the phone via USB to my PC but no matter what mode I put it in ADB never detects it.
The "green Start" is where you want to be here. That's the bootloader. You need to make sure the driver - assuming Windows - is set to ADB Bootloader Interface in Device Manager as well as make sure you have the latest version of the ADB / Fastboot package.

Hello, you can now restore only the bootloader and the system via fastboot. To do this, download the rom ,, https://xiaomirom.com/en/download/xiaomi-pad-5-nabu-stable-V13.0.4.0.RKXMIXM/#global-fastboot ".
You must have previously unlocked the bootloader via MI unlock tool before you can flash the Global rom .
Then you will have the normal Global MIUI Android on again.

Thanks, but the problem is that I flashed a different rom using the flash tool and accidentally looked the boot loader, after this it won't start, the boot loader is locked and I'm not able to do anything.
You should be able to unlock it again using the xiaomi unlock tool, because it should keep oem unlock setting open.
You must boot at fastboot and Unlovk with the Tool. You dosnt wait 7 days. It works Instant and then you can flash fastboot Rom of your choice
You mean you unlocked a global one and flashed a Europe official rom and locked it and it got stuck?? I'm in the same boat, i have TR and i want to flash EU. I'm waiting the 7 days at the moment to unlock the bootloader. Advice pls
