ZE551ML stuck in fastboot mode - ZenFone 2 Q&A, Help & Troubleshooting

Hello,
My Asus Zenfone 2 ZE551ML is stuck on fastboot mode and shows the message "continue the fastboot process".
Whichever option I choose, Normal Boot, Recovery Mode, Restart Bootloader, it boots back into the fastboot mode. I tried connecting it to my PC so that I could flash a recovery or flash it back to stock ROM but it does not get recognized by my PC. In device manager it shows Unknown USB Device (Port Reset Failed).
Can anyone please help me recovering my phone?
Thank you very much in advance. I would definitely treat you with coffee and some cookies.

[Q] Broken from update to Lollipop (stuck in fastboot)

I've seen some other people with this problem, but there have been no fixes.
The problem is that the phone was updated to Lollipop. It worked for a little bit, but after a couple of minutes lots of programs started force quitting, and it eventually turned off.
When it turns on, it takes about 20 minutes, and then goes into fastboot mode.
If I try to get into download mode, it stays on download mode for around 15 seconds, and then it continues into fastboot mode. Windows does not recognize the phone in download mode, so I can't restore anything from there.
What I have learned then is that I need to flash the laf.img file, which I got from download the official firmware from LG's website by inserting my IMEI, so it's the right version, and then trying both fastboot flash laf laf.img, as well as fastboot
boot laf.img. The problem is that they both fail writing, but it's not just that command. I can't do fastboot erase recovery, or fastboot erase anything, only thing that works is fastboot reboot.
Does this mean that the internal storage is broken? Is there anything else I can do? I can execute fastboot commands, but it seems like I cannot write anything. The drivers seem to be working, as it's recognized as a fastboot devices, but it only says
? fastboot devices
All commands result in a error(failure or something like that. I've removed the SD card as well, as I heard that might cause problems. As far as I know, I need to flash the laf.img to get into download mode, and from there on can flash via kdz.
Help please? This kind of sucks..
When you write a command, does it show on the phone?
You might need to change the driver in device manager. Look for "Android", update driver, browse my computer..., let me pick from a list, and here you'll see 3 different drivers, what you want is "Android bootloader interface"
hi

Stuck on the AP Fastboot Flash mode

Hey guys, My moto Z Play died on me, and it doesn't budge from the AP Fastboot Flash Mode.
I can do the selections using the volume keys but nothing happens when I try to select one of the mode, including the Start, Recovery Mode, QCOM, Bootloader logs. It just gets stuck there until I restart the phone again to this mode using the power and volume down keys.
Only option that works in here is the restart bootloader option which pushes it back to the same screen.
The problem here is I the USB debugging was not enabled before this happened, so I am not able to detect the phone in either the Adb fastboot or in RSD lite.
Looks like its been hardbricked or the internal storage has been corrupted.
Any suggesstions to be able to flash the stock firmware to my phone.
PS: Its a verizon phone.
thanks

The question is what did you do to the Verizon "unlocked bootlader" phone to get you to this point?

How to rescue data from J2 Prime stuck on boot-loop with no access to recovery mode?

Hi, hope someone can help me!
I accidentally got my Samsung Galaxy J2 Prime SM-G32M stuck in a boot loop, it happened after i tried to put a micro-sd card in it, after i removed the micro-sd it stayed on boot loop and couldn't boot into recovery (in Enigma NL for J2 Prime there is a bug where you need to enter TWRP and reboot into system for it to turn on properly because when you turn it off the Kernel dies)
It seemed like it couldn't boot into download mode as well but i eventually got it to enter download mode, my computer does not recognize the device, i am not sure but i assume usb debugging is not enabled due to that, it doesn't have root and it uses Enigma NL Custom ROM: https://forum.xda-developers.com/t/rom-6-01-stable-g532xx-enigmanl-port-rom-for-j2-prime.3951387/ and this TWRP port: https://forum.xda-developers.com/t/...axy-j2-grand-prime-plus-sm-g532f-g-m.3616589/
The home button is a little bad and doesn't work from time to time but i don't think it is the reason of it not being able to enter TWRP. The only thing i've got is download mode, no recovery and probable no usb debugging as well, i really need the data inside but i haven't found a way of rescuing it that doesn't require USB debugging or entering recovery mode . Is there a way that i can either access recovery mode or rescue the data inside the phone without it?
I really need the data inside the phone and programs like Samsung Switch said they couldn't connect to the phone properly, plsss help
(I also tried ADB to enter recovery mode using the command line but ADB does not recognize my device even when it is turned on(on boot loop) and also when it is on download mode.)
My computer does not recognize the device.

Did you install Samsung drivers correctly on your PC? If not then this would explain why your PC failed to recognize your device.
I suggest you install those drivers right away, and test to see if it works.

I'm stuck in the same step. However, I can reboot into twrp by connecting to a PC and typing fastboot reboot recovery. May have to repeat it sometimes. Apart from that, nothing else works, TWRP doesn't sideload.
1> Try booting into TWRP with "Fastboot boot twrp.img" and do complete device whipe from there.
OR
2> Find a matching RAW firmware from the forum here and re-flash the firmware from Fastboot
OR
3> If above not working, and EDL flash may be the only option out.

ASUS Zenfone 3 Deluxe Bootloop

Hi there !
I am writing to you today because I am trying to rescue an ASUS Zenfone 3 Deluxe that is stuck in Fastboot mode.
I am unable to enter recovery mode with the key combination POWER + VOL DOWN (bootloop)
I specify that the USB Debug mode is not activated...
Do you have a solution to recover the data present on it?
I have already tried with fastboot but impossible because it tells me that the phone is locked
ADB doesn't even recognize the model...
I'm listening to you !
Thanks
Same as above. Cannot enable USB debugging because the phone is in a BOOT LOOP.
Only Fastboot is available, down button has no effect.
Phone bootloader is locked and 'FASTBOOT OEM UNLOCK' produces an error.
