Soft Bricked KF2 won't connect to PC - Kindle Fire 2 Q&A, Help and Troubleshooting

So long story, mom got an iPad to replace old KF2. I took the KF2 after she hadn't touched it for over a month. I rooted, installed some apps, and then promptly bootlooped it (first time rooter, whoops). Then the very next day, she asks where it is, and I told her I took it. She said fine, just don't mess it up, I still need it. What for, I have no idea. Anyway, she finally decided she needed it back, and she plugged it in to charge and....bootloop. I tried to fix it, but after booting it into recovery, it won't connect to my PC anymore.
TL;DR: Bootlooped KF2 won't connect to PC, need to fix without deleting any data. Also, no fastboot cable on hand.
If you can help me here, you're a lifesaver

Hi there! If you could enter recovery try entering the adb sideload option, and check if your computer detects it. Then adb pull all your files, and follow the restore instrucciones, get back to stock and put your files back. Otherwise you'll need a fastboot cable, it saves lives. Reflash updated recovery and that should allow you yo acceso your files.

Root/Rom Help Needed ASAP!!!

Here is my issue..I have been rooted since I got the phone and actually rooted both of my EVO's. Last week I decided to go back to Fresh Rom 1.0 and inadvertently flashed a new theme at the same time. Did not flash the ROM and then go back in and flash the theme. As a result, the phone went into a continual cycle of rebooting the loading screen ( for Fresh users you know it has the little guys and says FRESSSHHH). Well that happens over and over again.
The only option I have is to take battery out and go into the bootloader mode. MY problem is this:
* Once in bootloader mode, I can't reflash because when I go into the recovery mode, the recovery says " ADB server is out date" and scrolls thru a few lines an disappears. I've tried every thing suggested to me and still have not been able to fix that.
* Cannot access root of SD card because system doesn't recognize the phone is attached.
* Tried to load PC36IMG file on the card manually and that loaded but I can't get to the restart option. It finds the file but does not give me the restart commands.
I'm at wits end right now. I tried the OTA Recovery but since I cannot connect to the computer, it won't run either.
Please help......
Restore a nandroid.
RUU start over.
I tried to do that but the computer - htc sync won't recognize the phone so I can't RUU again. When I get to the end of the process it tells me either the phone isn't connected to the USB or the USB isn't connected to the computer.
You phone says the ADB server is out of date when you boot into recovery?
It sounds like you are not completely rooted.
You should be able to volume down and power on. Then choose recovery. From there you can restore a backup. That should also give you ADB access to the phone (if you are fully rooted)
If you are not fully rooted, and you have to run some bat file on your computer to get the phone into full recovery, you may be skrewed.
No, the computer says that when I go into recovery mode and have the black screen and red triangle on it. I then go to the computer and try and run the recovery file that I've been running as I've flashed 10-12 ROMS already. The CMD screen on the computer comes up as ADB Server is out of date...and another line or two scrolls by and then it disappears, never connecting to the phone and going into the next screen where I can wipe or flash from SD..etc..
Sounds like you did not complete step 2 of the root process. You should be able to enter recovery without the use of a computer.
Reboot your computer and try again, if you still get errors then I am out of tips.

I bricked my KF GOOOOD this time

I have had a Kindle Fire since they day they came out. I immediately disliked the stock Rom so I ran the kindle fire utility and installed Fire Fire Fire and TWRP, rooted it, and installed CM7 Rom which has been working great. Transferred files and programs between my PC and Kindle with no issue for months. Now with all the ICS roms available and working I decided to try and upgrade to one of those and thats when everything went wrong. Its in a bootloop and the triangle appears, fades, lights up again and immediately boots to TWRP. I have flashed the entire kindle using TWRP trying to get everything off of it. Upon plugging it into my PC BRIEFLY when the triangle logo pops up I get a "USB device not recognized" on my PC. I have tried using KFUtility to reinstall drivers, tried uninstalling n reinstalling drivers but the same thing happens. I cannot use TWRP to mount at all, nothing happens. Kindle Fire UTility keeps saying adb offline, CMD adb devices also results in 0 devices found. I have tried putting it on normal boot using both ADB and KFUtility and it says "wait for device" and nothing ever happens. Any idea? Not even sure if I have a rom installed on my kindle anymore but my PC wontread it so I cannot push another image to it. Got a plane trip on Saturday and would love to have this working to kill the bordom lol. Any advise would be greatly appreciated.
It sounds like your bootmode is set to recovery. An easy way to fix this is download FFF1.4 to your computer and use the mount function in recovery to place it on your sdcard.
Flash it in recovery as you would a rom except don't wipe anything. When you reboot, hold the power button like you're trying to enter recovery and you'll be given the option to reset the bootmode.
Thank you so much for your advice but there in lies the problem. Inside the recovery console i choose to mount it and nothing happens. My PC will not let me access the kindle in anyway at all, either mounting the SD Card or via ADB/KFUtility.

Generally, the only thing that would prevent adb/kfu from communicating with the device is the drivers. Make sure they're installed properly. You may have to uninstall them (delete if applicable) and reinstall them.
Follow the instructions in this guide to install and verify your drivers.

K heres the latest (we r making progress!)
I got my device to be detected by my PC and used KFutility to change it to normal boot. Now instead of booting into recovery everytime it boots normally.... to a black screen (guessing my rom is shot or I deleted it while playing with it). The issue is the ONLY time my PC recognizes my kindle is for a .5 second period when i first turn my KF on and the yellow triangle appears. I can use this window to change it to normal bootmode, reinstall TeamWin, stuff like that, but i cannot mount it so I can transfer or adb so I can push. You can watch device manager and it'll pop up ADB android phone or whatever it should but poof, a second later gone.

Get your device drivers working so you can use adb. Follow the instructions in the post below...
http://forum.xda-developers.com/showpost.php?p=26144447
That is excellent advice and I wish it would work but I cannot pull up ADB once in TeamWin. Keeps saying no devices. As i said my PC detects it and ADB will detect it for .5 seconds on the orange triangle. Once the orange triangle disappears and it either boots to blackness or boots to TeamWin ADB stops recognizing my device. But I will play around with your suggestions once I get off work and let you know what i find out. Thanks again for everyones support.
Frozen screen during rooting
Hi,
I am new to the forum. I have a kF screen stuck (where it says 'kindle fire') while I was trying to root it. I tried hard reset, charging for half hour, calling AMAZON...nothing works. The screen goes off if I hold it for 20 seconds but when I put it back on same thing. I was trying to root it with 'fastboot (?). Is there anything at all I can do? Thanks.

Wipe everything

I want to wipe everything off my Kindle including the recovery and bootloader, is there a command I can issue to do this? (I'll be using firekit /w the short trick and adb push to reinstall my rom/bootloader/recovery)
I can't even begin to tell you why that's a bad idea and completely unnecessary.
Do you mind me asking what you are trying to accomplish with this and why you think it's necessary?
I had the old version of TWRP and bricked my Kindle, I got it to load the new version of TWRP with firekit and it unbricked my Kindle. Next, I set boot mode to normal because I wanted to flash a new rom, however then I got the blinking yellow triangle of death again, I ran usb_fix_parts_and_install_fff_twrp (how I unbricked it before) and shorted it but this time it didn't work and I got the blinking triangle again. So I though if it worked before with new version of TWRP maybe if I removed it completely and the re-ran "usb_fix_parts_and_install_fff_twrp" it would unbrick my Kindle again
Sorry for the long explanation
Oh I forgot, The reason I put it back in normal mode is because I thought I fixed everything and thought the battery would begin to recharge again, so I figured just downloading the rom to kindle itself would be easier than using adb push to transfer it from my computer, but then I couldn't even get back to twrp after the first time
The blinking triangle is due to a dead battery, not the bootloader installation.
Unplug the device and hold the power button until it shuts down completely.
Plug the device into your computer's USB (2.0) port and immediately hold the power button until it shuts off again.
If you can get it to shut down without starting up again, leave it plugged in for at least half a day to let it charge.

I'll try that, thank-you

Bricked my Kindle cannot figure it out

Ok so, my brother gave my parents a kindle that had TWRP, FFF, and Cyanogen mod on it (not sure what version). My mom tried to use it one day, but it wouldn't go past the FFF yellow triangle thing so she gave it to me to try and fix. I went into TWRP and wiped the cache and did a factory reset and that didn't do anything. I found this thread (http://forum.xda-developers.com/showthread.php?t=1638452) to try and revert it to the stock software, now this is where I think I messed something up. After I installed the update onto the kindle with TWRP I rebooted the device and now, it will boot onto the normal white and orange KF screen but won't go anywhere past that. I can't get back into TWRP or anything it just stays at the logo screen. I can control is using ADB but not fastboot. With certain ADB commands though it says - exec '/system/bin/sh' failed: No such file or directory <2> -
I've been trying to fix it for 2 or 3 days now and cannot figure it out, I've been looking through these forums and have tried numerous things but nothing seems to work. Please help me haha
You need a fastboot cable & Soupkit my dude. I just started tinkering with it not too long ago after I let it set for almost a year lol. Here, I'll like you to the one I got.
Also get ready to put Linux on your PC. Here is my previous thread that I had to figure out how to fix myself.

Bricked my Fire TV Stick 1?

Hi there!
I think I may have bricked my Fire TV Stick 1 (bought at launch in Germany)...
Current situation:
- stick turns on, shows white amazon logo on black background
- continuously rebooting; ~5s black screen, ~5s amazon logo
After months not having it used, I found out I may be able to root it by now. So I did research over the vast amount of threads and posts and was overwhelmed by the information... So I tried to get started but struggled to find the right steps and therefore maybe failed.
I updated it to 5.0.5 (stock) and tried King Root, then Kingo Root, which was a success.
I tried to use the TWRP 3.0.0-7 v2 zip and used the sh command from the respective thread (I thought that was it, since all my devices before used either TWRP or CWM).
To this point, all went through and I wanted to reboot into recovery, but there was only this generic (stock?) red text recovery screen. I waited to be sure, nothing happened and I unplugged it to reboot.
It booted fine and I reflashed the TWRP zip, in case I didn't do it properly. Again it did as expected.
I then pushed the latest prerooted 5.2.0.1 zip and rebooted to recovery, but again this generic screen, so I unplugged it early, I think.
From there on, I got stuck at the white amazon logo, see above.
I did not unlock the bootloader, adb shell confirmed it not being unlocked before.
During bootloops, I did not manage to get any control via adb or fastboot.
So, is it bricked once and for all? If not, how can I save it?
I don't care about anything stored on it.
I also have a Y-USB-OTG cable and connected a keyboard before, but could not interfere yet.
(If bricked, would a Teensy be of any use? I have one from CCast rooting days)
Thanks for reading and in advance.
I had same problem with my fire stick when used the USB power of my TV.
Did you try to power the fire stick TV with the power point and USB adapter?

I guess you did not read enough.
At this point in time you can only root (kingoroot or kingroot) and replace root with SuperSu on a Firestick. TWRP (recovery) can not be installed because it was not released by rbox as of yet, that particular recovery\pre-rooted image is for firetv1 upgraded to OS5 and not for firestick.
Sorry man.
Have you tried to connect to a computer via USB and run kingoroot or kingroot for windows (whatever you used)? It is a small chance that will recover but it is a slim one....

I could not remember, so I just retried it with two different chargers and two different cables (both used to power my Nexus 5).
Unfortunately resulting in the very same loop... But thanks nonetheless.

Dang... Usually I don't make mistakes this dumb. Guess I learned my first lesson. I'll try to trace my mistake though, for future attempts.
I rooted it with the Kingo app, I think, and got that typical "stuck at 90%" and rebooted it like others did. It rebooted fine and Kingo verified it rooted.
I did not use Windows, I use Ubuntu, occasionally with Wine, yet I had no luck passing USB devices to it. (And always these missing libs...)
Normally, adb and fastboot (console) work fine (i.e. with my phone).
Now I have no chance to interfere with the bootloop, I think.
IIRC, sometimes I could spam commands and at one point adb was stuck at "waiting for device".
I tried to reproduce it just now, but could not get it again.
So, should I try adb or fastboot on another computer to be sure?
Would King(o) for Windows be of any help at this point? If so, what would be my best bet to catch it at some point I can recover it?
Is there any other way I could try? From my nooby perspective, could the bootsplash be an entrance for fastboot? Could it be just stuck trying to access erroneous partitions?
At this point I would try the most crazy and risky idea, since it is unusable anyway.
Thanks both of you for your answers.

Do you still have root? Is your stick responding to the su command?
If so read this post: http://forum.xda-developers.com/fire-tv/help/guidance-recovering-bootloop-firetv-t3446902
If not:
Try kingoroot for windows however it is a slim change in my opinion as you wrote a FireTv image to your FireStick.
Copy and paste from: http://forum.xda-developers.com/fire-tv/development/guide-fire-stick-replace-king-o-root-t3440923
"IF YOU RUN INTO SOFTBRICK ISSUE (stuck at fire tv logo)
Make sure you have ADB drivers properly installed in your windows pc/laptop.
connect a genuine usb lead to the firestick/pc.
download the windows version of KINGO ROOT and install it.
open KINGO ROOT on the pc with Fire Stick connected up to pc and tv.
wait for the button to pop up and click root.
if you dont see AFTV or get enable debugging in the KINGO ROOT program on pc/laptop please unplug the stick from usb and replug it back in.
if this still wont work restart the pc/laptop or try another pc/laptop.
you should after clicking root boot back up into your homescreen, if it doesnt boot back into your homescreen automatically, wait around 5 minutes and unplug usb and re-plug it again. "

Thanks for the links, but from what I see, I need to get past the bootloader splash for adb to work. I'm stuck at the white "amazon" splash, not the colored "FireTV Stick" splash after the amazon one.
Sorry for not making it clear (and for that amount of text that maybe hid it)...
From what I understand and recall, I did only flash the recovery, right? Or does it automatically flash the zip I pushed to internal storage?
And what confuses me, the first attempt booting into recovery AFTER flashing the wrong one I got the former mentioned screen with red text. Reboot worked and the Stick was running. So I did retry and got the same red text after rebooting to recovery. I assumed it did not flash again and unplugged it earlier than the first attempt. Since then it got stuck at the white bootsplash.
Since I am still a noob, it seems to me the system wasn't touched, maybe a faulty recovery integrity forcing the bootloader to loop.

I have no idea what you did however it will not automatically flash your zip, problem is you installed TRWP that was not meant for Firestick and overwrote its booting sequence. You most probably would had recover from your first attempt by re-installing a new image but once you tried to install it again it most probably finished writing the whole thing and damaged booting sequence.

Yeah, sad thing I got the wrong device, should have taken my time even more...
I googled the screen I got to two times before getting stuck:
http://forum.xda-developers.com/showpost.php?p=65968901&postcount=60
First time I waited approx. 15 minutes before pulling the plug to reboot. Since I noticed no difference I tried again and got the same screen. But this time I pulled the plug earlier, <1 minute.
I'd like to add that my bootloader was locked. Can I damage the booting sequence by corrupting the recovery or was my mistake that major to be able to do that?
I googled some key combinations to get into recovery or to bypass it, but I don't know if I get the right keys.
With my remote control I don't think I have enough time to hold the keys. Additionally I have a USB keyboard (Cherry KC1000; if possible, which keys btw?) and may be able to connect it via powered Y OTG cable.
So if anyone got any further input or ideas for me to rescue my FTVS, I'd be glad to receive it.
Thanks to all.
Anyone else maybe an idea?
The thing is, I cannot believe it is unsavable.
To summarize the current state (please see full details above):
- stuck in bootloop, white amazon logo
- flashed wrong recovery, after first flash the system booted, after second flash it got stuck (characteristics above)
- never flashed anything other than recovery
Strange thing it booted in first place, but now it refuses. Also I got the screen I mentioned above and unplugged as described above.
Can I possibly bypass the recovery check and try to boot directly to system? Or maybe interrupt for fastboot access?
If connected to PC, can you see it thru 'lsusb'? Or 'dmesg | tail'?

I tried both
watch -n 0.5 'dmesg | tail'
and
watch -n 0.5 'lsusb'
but with no identification whatsoever.
I double-checked with my Nexus 5 on the same port with the same cable, it identified fine.
One last bump for ideas before putting it into the trash.
