[Q] Can't get fastboot even with cable.

Windows 7, completely fresh installation, plug powered down kindle fire in with fastboot cable and just boots regularly. I cannot figure this out at all! Please help.

Update
Okay, so I was able to switch back to an ubuntu system and here is what I have:
I can enter fastboot mode and perform operations. Following the twrp - second bootloader guide results in a boot loops and I am unable to get past the orange kindle fire logo, it doesn't do anything at all.
Under linux does anyone know what I need to do to get this thing working again!? I have never had so many problems with a device! Ahhh, wish I hadn't tried to add wallpapers.
The issues started when I tried to push framework.odex and services.odex and it didn't go.

Solved
Okay, for anyone running Ubuntu like I was and stuck in a boot loop here's what I did:
Download stock recovery.img and boot.img.
Download KFHD_SRT V ??? tool or any other stock system.img.
Flash the three files using fastboot, then reboot will give you all stock restore.

Ascend Mate soft brick (I think)

Dear all, I would reset my Mate and did a factory reset from Android Menu. After that the phone was going to the TWRP Recovery. So I didn't read further tutorials and thought a full wipe would not a bad Idea. But sadly I did not found the old Custom Image ZIP file and would install the factory default firmware. UPDATE.APP. After some doings I lost my TWRP Image (I think by swiping) and now I have only the HUAWEI SDCARD&USB UPDATE AGENT VERSION 2.0 running.
When I try now to update of UPDATE.APP from SDCARD, the error is, the Agent can not mount. I was trying two SD Cards. fresh formatted.
Are all sizes compatible? Or do I have to use a small SD card?

Hi all, I found this instruction: http://forum.xda-developers.com/showthread.php?t=2682979

Why it is taking so much time(almost one hour) to erase the system? Is it normal? What should I do?

Stuck on TWRP after accidental factory reset

I was about to manually install the lineageOS update, but I accidentally swiped factory restore. Is there anyway I can get the update file online? I tried starting from the top by wiping everything and reinstalling the rom but it only boots me into TWRP. I also tried restoring backup files but is also boots me into TWRP. I am stuck.
PS: I tried the "fastboot continue" method but it boots me into TWRP.

reboot to fastboot mode. flash stock bootloader and recovery. reboot in stock recovery and then factory reset device and sideload firmware. alternatively you can flash raw firmware manually

Thank you for your response, Sir. I really appreciate it. Where do I get the stock bootloader and recovery, and how do I flash them? On the alternative method, do you mean I should install the stock rom? I'm sorry. I'm really not good at this; I'm just good at following tutorials. Is this what you're suggesting me to do? (XDA is now allowing me to write outside links. But here is the title of the tutorial from Asus Zentalk)
"[Experience Sharing] How to Relock Bootloader on ZenFone 2(ZE551ML ONLY)"
I have made a backup before I intalled the Lineage OS custom Rom. Can I use that instead of downloading new files, because the internet here is really bad. My problem is how I am going to install it. I tried restoring it but I keep on coming back to the TWRP.
Edit: I am now downloading the stock boot.img and recovery.img. I will be flashing them with ADB the ADB tool. Is this what you want to tell me? Then I will reboot in stock recovery, select factory reset and sideload firmware. I honestly don't get the "sideload firmware" part but can I use the one that I have backed up? How?

the backup you made you can flash only via twrp. if you have backup simply install it in twrp. but if still bootloops then you have to download firmware either from asus website or raw firmware from any other source. first try to flash backup in twrp. if you are unable to get into system them report back here. i will send you link to download raw firmware and instructions how to flash

I tried to flash the backup but still no luck. Yes, please. Thank you very much!
I'm currently downloading the "CleanSTOCK-MM.223-v3.8[STABLE][Z00A]-6 May". I hope this will fix the problem. Do you think this will work 100%? I am afraid that it will boot again to TWRP after installing another rom. Which do you think is more efficient, installing a new rom or installing raw firmware?

In general, 3 things are needed to use Android GSI:
a device is fully Treble compliant (Treble support is mandatory for devices launched with Android 9 or later).
the device's bootloader could be unlocked.
the tools and procedures to update OS for the device.

Thanks, I'll try, can't boot to the system and booting to a recovery is crashing my phone (f.e
