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.

Don't hijack the threads please. If you have a problem or question, post it in the Q&A section.
I have had my Kindle Fire for over a year and I have used various ROMs. Most recently, I was using the HellFire ROM and it crashed out on me. I decided to go back to stock for a while but noticed a new version of FFF (v1.4a) so decided to install that. Now, it boots to the FFF screen but nothing else. I cannot enter the boot menu. My computer does not recognize the device (no sound from the computer recognizing that it was plugged in) with either a regular or factory USB cable (I've used the factory cable before to unbrick the device).
I have read through the other posts regarding similar problems but all of those posts were resolved with either a driver problem or with a factory cable. None of the utilities or terminal commands are useful since the device is not recognized.
I have let the battery completely drain (letting it sit in a drawer while I take a break from the problem). It does recharge with the factory charger, but one thing of note is that the LED stays green during the charge. It never turns amber either on the charger or when it is connected to the computer.
Anyone have any ideas? I've been scratching my head lots over this. Many thanks for anyone willing to scratch along with me.
So have you tried Soupkit? How did you flash your bootloader?

First of all, thanks for replying and trying to help. I have tried SoupKit and the Macintosh utilities but I keep getting the same response "Your device appears to be offline."
I originally rooted the kindle by manually entering adb commands. I installed the bootloader with KFU.
Is the bootloader splash static or does it blink on and off? Are you able to accces the boot menu to reset bootmode or enter recovery or select normal boot?

The bootloader splash is static. I am unable to access the boot menu at all.
I have been playing with the "short the point" install TWRP over USB but to no avail. I get "waiting for OMAP44xx device" and that's all.
Right, so, I've done some googling and some searching about here and there but either I'm being dense and the solution is really simple, or nobody's done what I've done with this tablet before and, again, I'm being dense. Here's my issue:
Kindle Fire 2 (2nd gen, also second-hand) tablet: stock, rooted, that worked fine with the tool by bin4ry.
Rebooted after that, verified root was working, adb and fastboot perfectly fine (sidenote: linux user, no shonky Windows drivers at fault here)
My ultimate goal is to get CM on this device, so, started after this to follow the instructions in this thread regarding getting the second bootloader on the tablet.
Realised I need a factory cable, ordered, delivered, works but not all the time, I'm not sure if it's a dodgy cable or not but did get into fastboot.
Got new bootloader installed, saw Kindle Fire logo in blue. Proceeded to boot the stock rom after this and use adb push to put the CM 11 zip and the gapps zip files on /sdcard.
adb shell, su, reboot recovery, intending to boot into TWRP to flash new rom
Tablet reboots, but is now stuck with the stock boot logo (orange) and then a black screen with a white triangle and exclamation mark on it. I haven't seen any references to this particular delight.
Fastboot cable does not, no matter how I fiddle with it, put the tablet in fastboot mode. Holding down the power button for five minutes did nothing.
I've read that if it turns on, it can probably be recovered, but I don't know what to do from here. Can anyone render assistance?
So, after much fiddling, I discovered that my problem was actually that my fastboot cable was loose in the microUSB end, and not contacting properly with the pins - thus not sending the tablet the requisite signal to enter fastboot mode.
I've successfully got TWRP onto the fire and thus CM 10.1 now.
I hope this update helps anyone who finds themselves in a similar situation; fastboot still works, keep wiggling.

I had this problem with a 2nd gen Kindle that was also second hand.
Phoned Amazon UK, described the problem (not mentioning I'd done it myself) and they replaced it.
Seems there's not a lot they won't replace.
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.
Ok, so I’ve run myself off the road into a deep hole and am hoping someone can help me climb out and get back onto the correct path.
I have a Motorola Moto G7 Play 1952-4 (channel). My goal is to install TWRP, and LineageOS 18.1 with GAPPS. Root is not important at the moment.
Here’s what I did:
After successfully unlocking the bootloader (thank you Motorola), I downloaded TWRP for Chanel from the TWRP.me site. My plan was to first install TWRP, then use TWRP’s install feature for LoS 18.1 and the GAPPS.
To install TWRP recovery, I followed the instructions on the TWRP site. After starting the ADB server on my Windows 10 PC and booting the phone into the stock recovery, I used “adb boot twrp-3.5.2_10-0-channel.img” to temporarily boot into TWRP recovery. I then used ADB to push TWRP.zip onto the internal SDCARD. I used TWRP’s install feature to install "twrp-installer-3.5.2_10-0-channel.zip", presumably to both slots. To the best of my memory, everything completed correctly.
BUT . . . when I powered down the phone and attempted to boot into recovery, all I got was a black screen with a small N/A in the upper left corner instead of the familiar TWRP screens. After a while, the phone booted itself into the stock U.S. Cellular Android 10 (Hell Oh - Moe Toe). I've done several power-off/power-on cycles to no avail. I am able to get to and use the stock OS.
So, like TWRP.me suggests, I figured I’d just flash it back to stock and start over. Um, nope. I can Vol-DN/Power to the bootloader menu, but “adb devices” doesn’t see the phone, preventing me from flashing anything. USB Debugging is enabled and the phone says "USB Transfer Mode: Connected". “adb devices” sees the phone while Android 10 is running, but as soon as I boot into recovery, the phone “disappears” from ADB.
The only other thing I could think to do was to use the “Rescue” function in the Lenovo/Motorola Smart Assistant. While ADB can’t see the phone, LMSC sees it just fine and I was able to rescue/reinstall the stock OS successfully, or so LMSC said. Unfortunately, LMSC doesn’t seem to fix whatever is wrong with the recovery. Interestingly, “N/A” no longer appears after Vol-DN/Power and select Recovery Mode, the black screen now says “bad key”, followed a little while later by the Android logo with a “!” in the middle of the screen and “No command” below it.
And that’s the hole I now reside in. Despite considerable searching/reading here at XDA, I'm at a total loss for what to do next.
SOOOO, I’m hoping someone can help me:
1. Fix the N/A black screen
2. Get into a mode that ADB can see
3. Properly install TWRP
Thank you in advance,
Tenaya
Did you flash the copy-partitions.zip while in TWRP?
Maybe you could borrow some ideas from the official install instructions for LineageOS.
Install LineageOS on channel | LineageOS Wiki

I had some strange intermittent USB connectivity issues with a few Moto G7 Plus devices with my main laptop, but was fine connecting on a 12 year old desktop computer. So perhaps you could check to see if adb connects on another machine. Only other idea I have is to somehow flash back to stock again with fastboot.

No, I didn't know I needed to; nothing about that is mentioned by TWRP.me.
This is unknown territory for me, but your question sparks a thought for me. I wonder if 1) The stock recovery is in the "other" slot, and 2) there is some way to boot from it. That could be a way to sidestep the ADB devices problem I'm having?

At the moment, I have no way to do that. I don't think the USB connection is the culprit, ADB "sees" the phone just fine while the phone is in the stock OS, just not in recovery (EDL?.

That's my current plan, but FASTBOOT won't flash anything while ADB devices won't/can't see the phone. I'm hoping someone has a workaround of some sort for that.

Hi, first of all lets set some things straight, you are experiencing a Boot Loop, in other words a software brick. (Soft Brick) now luckily these are fairly simple to fix. Sorry to break it to you but the N/A Screen won't disappear, that used to be the Blue/Yellow Motorola Splash Screen, but since you unlocked your phone it'll only show N/A but thats okay there are tools that can help you customize this and change it later on.
Now why is it on a boot loop you may ask, well that is because there is no more operating system to load in. But worry not, try to get into your bootloader, and try to connect adb through there.

I can Vol-DN/Power to the bootloader menu, but “adb devices” doesn’t see the phone, preventing me from flashing anything. USB Debugging is enabled and the phone says "USB Transfer Mode: Connected". “adb devices” sees the phone while Android 10 is running, but as soon as I boot into recovery, the phone “disappears” from ADB.
The only other thing I could think to do was to use the “Rescue” function in the Lenovo/Motorola Smart Assistant. While ADB can’t see the phone, LMSC sees it just fine and I was able to rescue/reinstall the stock OS successfully, or so LMSC said. Unfortunately, LMSC doesn’t seem to fix whatever is wrong with the recovery. Interestingly, “N/A” no longer appears after Vol-DN/Power and select Recovery Mode, the black screen now says “bad key”, followed a little while later by the Android logo with a “!” in the middle of the screen and “No command” below it.
And that’s the hole I now reside in. Despite considerable searching/reading here at XDA, I'm at a total loss for what to do next.
SOOOO, I’m hoping someone can help me:
1. Fix the N/A black screen
2. Get into a mode that ADB can see
3. Properly install TWRP
Thank you in advance,
Tenaya

HellxDo,
Thanks for the reply.
After I used LSMC to "rescue" the phone, it stopped displaying N/A" and began showing "Bad key". Different, but not better.

Now why is it on a boot loop you may ask, well that is because there is no more operating system to load in.

Hmmm . . . The phone currently boots into the stock rom (U.S. Cellular Android 10) if I wait a while after "Bad key" displays. If there's no more OS to load in, how do it do dat?

But worry not, try to get into your bootloader, and try to connect adb through there.

My (limited) understanding is that the only way to "get into" my bootloader was with the Vol-DN/PWR button combination. When I do that , I get the bootloader menu, but ADB doesn't/can't see the phone - nothing is listed when I run ADB devices and fastboot won't/can't flash anything.
Is there a different/better way to get into my bootloader?

And the adventure continues. Here's some more information.
While continuing to research this, I was wondering if there was another way to boot the phone into EDL mode and Google found some instructions at thecustomdroid.com for using ADB to boot the phone into EDL. I booted the phone to the stock OS and used the command adb reboot edl. The phone immediately went blank, followed shortly by the "bad key" message. After a while it again booted into the stock rom.
I still cannot use fastboot because it doesn't/can't see the phone.
I have also discovered that if i use VOL-UP/PWR, the phone boots directly to "bad key", followed by the stock rom. Another dead end.
I also used LMSC to "Rescue" the phone again and learned several things:
While LMSC is running, it boots the phone into the bootloader menu and begins to flash. If I do adb devices while LMSC is flashing, the phone STILL doesn't appear in the list.
LMSC definitely flashed the stock OS - when the phone rebooted, it was back to the stock OS Android start screen as if it had never been configured.
There is still no recovery and I still can't flash anything.
LMSC is somehow able to flash without a recovery present.
Anyone have any other ideas?

If "fastboot devices" can't see your device while in bootloader mode, that could be the same issue I had relating to your USB compatibility with your computer. Try to borrow someone else's computer, install "platform-tools" to see if the "fastboot devices" command works.
If that works, next see if the command "fastboot getvar all" works. You should get many lines of info come up. If it gets stuck after a couple of lines, then the symptoms are the same as what I had. I have a bunch of really old laptops and a desktop sitting around with platform-tools just for this issue. I have heard others say that plugging the phone in via a USB hub sometimes gets fastboot to connect properly, but I haven't had success yet.
OK, some progress.
I found this:
[GUIDE][TOOL] Reboot to EDL mode from FASTBOOT! No More "Test Point Method"! [kenzo]
kenzo has graciously hacked fastboot.exe to force the phone into EDL mode. Using that, the phone booted into EDL and fastboot devices can now "see" the phone. Thank you kenzo.
BTW, kenzo's fastboot-edl isn't G7 Play specific, it was originally for the Xiaomi Redme Note 3 and seems to work for some other Android phones as well.
I'm still working on getting TWRP and LoS installed, but at least fastboot can talk to the phone.

I also had no luck with a USB hub.
I haven't tried another computer yet; I'm going to see what I can accomplish with fastboot-edl.
