[Q] KF 2 GEN not seen my computer on fast boot cable.

Rank newbie here. I did l watch the video of forum instructions for newbies and I have looked high and low for an answer I could understand. I am still stuck so reluctantly....Here we go...
I rooted my KF 2 Gen and had no problem doing so. Installed Google aps store, launchers etc. all on the stock OS.
All worked well until I got smart and decided to try a custom rom. It seemed to install fine. Asked all the options as I installed. Did I want Chrome, what launchers, etc. I wiped all the cache options and system. Went through all those screens and when it finally booted, I am stuck at the stock Kindle Fire logo in a boot loop. It will not connect to the computer. It seems to boot before it is recognized Dug on this forum, made myself a "factory cable" and it does work. When I plug it in, I get the Kindle logo a moment then a flashing gif of a stop light blinking red and green with the words. "Fast Boot" at the top of the screen. The problem is, I can not get the computer to "see" the Kindle Fire 2 Gen on this fast boot/ factory cable. I have tried switching ports, all the suggestions. The cable will launch the tablet into fast boot mode just fine however, the tablet does not connect to the computer. ( Windows XP Pro SP 3). I think I can figure out how to flash and restore on my own if I can get the tablet to communicate with the computer. I have no idea where to go now other than having a brand new paperweight. I just bought it two days prior and I suppose I could return it but the issues were caused by me so I don't feel like it's their duty to replace it.
Thanking you in advance for your assistance.

Go into TWRP, factory reset, and try again.

Thank you for your reply.
Sadly, the boot sequence terminates and it reboots before it ever gets to the TWRP stage.

When your device boots, do you see the blue Kindle Fire logo at any point?

Got it going! Thanks to this forum!

No, Soup. I would never get to the blue logo but....
I got it flying! After I got to fast boot, I swapped the fast boot cable to a regular cable and all was down hill from there on. I'm looking at a booted tablet.
Beers on me next time I am in Austin!

Can someone fix my Kindle?

Well I was getting the itch to flash a new ROM as I was running CM11. Thought it was a good idea to download one through GooManager.
Anyways, I flashed the ROM and GApps for 4.4 and now all it does it boot to the orange Kindle logo then a white line a few pixels thick appears down the left side.
I can't get it to boot into recovery holding any of the buttons but it will turn off and "on" with the power button. Any ideas?

Sounds like you will have to restore from fastboot mode, hopefully your pc will still detect it as a jem device for a very breif moment when it turns on on the orange logo. If it can you can just run
Code:
fastboot -i 0x1949 getvar product
and then plug the device in while its off and reflash with kindle fire first aid. Might be a pain to get the drivers to install for fastboot though because it doesnt show up for very long. If you don't have drivers installed and cant get them to isntall in time before it disconnects a Ubuntu live cd/usb is a good way to go, it doesnt have to install drivers because they are built into the kernel so it works instantly.

Okay, I was able to get it into Fastboot mode. However I'm at a loss of how to flash a recovery and/or ROM through Fastboot.

You mist flash stock files first. Your device has to be functioning before recovery and ROM and that good stuff

Thanks guys! I eventually figured it out.
The whole going back to stock was stopping the process, got it up and running again.
Whew!

Can't access bootloader, stuck on Update-Crash-Reboot loop

So I just got a Zenfone 2 in the mail today, finally upgrading my phone after 2 years, except when I was running through the apps, I figured I'd install system updates.
Except it just loads up, tries to install it, 1/4th way through it freezes, then after a few minutes it resets itself.
I've tried to hard reset it by going to the bootloader menu but when I hit Recovery Mode, it resets back into system update loop
Edit - Nevermind, after hours of researching, I've learned the glory of fastboot and adb

That's normal. Stock recovery will always show installing update and then pop up an error message.
When the error Android bot shows, hold down power button and press volume up. Release both at the same time quickly. Do it right and the real recovery menu will show up.

Since your phone is still fresh and new and you shouldn't have any data you wanna keep on it, http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE551ML/UL-Z00A-WW-2.20.40.59-user.zip
Download the full firmware for latest stock ROM and update it through adb sideload in stock recovery.

We have all been there... I modified my S2 years ago and the learning curve is impressive but fast.
For the Zenfone2 I also had to redo the whole fastboot/sideload yesterday after a failed update...

[SOLVED][ZE551ML] I bricked my phone. Can´t enter bootloader or recovery. Bootloop

I was already using a custom rom and I wanted to update my Twrp from 2.8 to 3.0. So I booted to twrp, then I flashed twrp 3.0 using the Install menu and selecting the proper twrp image. But in the flash screen I ticked the boot partition and flashed. Immediately my phone turned off and now I can't enter recovery and my phone is on a bootloop without any system it seems (even though I actually have cyanogen 13 installed). The only thing it does is show the Asus logo and then reboot. I can't boot the bootloader or recovery.
I don't know what to do. It's the first time I actually brick a phone =/
Any help will be great!Thanks
EDIT: well... I installed intelSOC, connected my phone to my PC and after some bootloops it suddenly booted to twrp (I didnt do anything) , then I reinstalled my rom and it seems everything is normal now.

After many tries my TWRP wouldnt get past the blue logo screen. Then I decided to follow this tutorial http://techtrickz.com/how-to/unbrick-a-bricked-zenfone-2-ze550mlze551ml-restore-bootloader/
After doing every step, my ASUS LOGO is gone, replaced by something it seems a Flag with pink, yellow and purple horizontal lines, and nothing else. The phone boots, shows this flag and there is nothing else I can do.
Ideas?

I believe if you miss going into twrp (odin should have auto reset off in options) then android tries to replace the custom recovery with stock, causing the bootloop...I could be wrong tho.

are you asia or europe? your device a505F OR SOMETHING?
OK try this method https://www.youtube.com/watch?v=fu7Eu3D6N0k
