[Q] "fasboot getvar product" command not working - Kindle Fire Q&A, Help & Troubleshooting

I have a kindle fire (first version Amazon came out with) which I rooted and installed CM7 on. The other day, I turned it on and it's just rebooting to the yellow triangle (fire logo). I ordered a fastboot cable and plugged it in but when I run 'fastboot getvar product' the boot loop still continues. The only output from fastboot is:
# fastboot getvar product
< waiting for device >
product: kindle
finished. total time: 0.000s
Any idea what's wrong?

What are you expecting to happen when using the "getvar product" command?

Uh...I thought the point of issuing the fastboot command was to get the Kindle out of the infiinte boot loop so I could reflash a recovery image, not to actually get the product ID: "Issuing a fastboot command like...fastboot getvar product to the device during this time will stop the fastboot countdown and enable fastboot mode indefinitely." Am I supposed to just try and flash the recovery image via fastboot while the thing is rebooting every 5 seconds? (eg:
fastboot flash recovery \path\to\recovery.img).

The 'getvar product" command, as you would think, just displays the product name. The point of using it is because, like most other fastboot commands, it waits for a handshake from the device before executing, but doesn't do any actual manipulation. The stock bootloader listens for such commands during the first few seconds of the boot process. As soon as one is detected, fastboot mode is then enabled.
You use fastboot mode to overwrite partitions with a disk image, which is what is needed many times to restore the device.
But your problem seems to be a (near) dead battery. The device has to boot to a certain point before charging is enabled so you'll have to use a different method to get it to charge. When you hold the power button, a countdown begins. During this countdown, one of the things that happens is that it prepares the device to be charged. The best way to do this is hold the power button until the device shuts off, then plug it into a power source and immediately hold the power button to shut it off again. If you can get the device to stay off while plugged in, leave it alone for several hours before starting it up again.
With a good charge, you should be able to restore your device using fastboot to replace the boot, recovery and system partition images (depending on what caused the "brick" in the first place).
Forgot what forum I was in

I've had it plugged in via USB for a day or so but it just kept rebooting so I just dug out a wall-wart charger and plugged it in. It's not rebooting at least. It came up to the FFF logo and stayed there so I think you've found the problem. I unplugged the wall-wart and plugged in the USB cable and it stayed in fastboot mode :good: I turned it off with the power button and will see if it just powers on normally later today. Thanks!
Hey, just an update. I got side-tracked with some other stuff and didn't get around to fixing my kindle until today. I plugged it in via the wall-wart charger for two days straight. Plugged in the regular usb cable and it booted to the FFF logo (yellow triangle) but wouldn't go any further. At least it wasn't powering off now... I was going to re-install u-boot and TWRP but figured I should at first try re-setting the bootmode as I recall that getting messed up once before. I ran
fastboot -i 0x1949 oem idme bootmode 4000
Click to expand...
Click to collapse
and then
fastboot -i 0x1949 reboot
Click to expand...

and Cyanogenmod came back up without any further monkeying around! Thanks again for the help!

[Q] kindle stuck in fastboot mode but won't accept commands

I tried to install CM9 to my kindle, but I didn't realize I was supposed to install TWRP first. I am stuck at the yellow triangle, can't get into recovery (of any sort).
When I plug in the USB cable I type in
Code:
fastboot getvar product
which returns: kindle.
I tried to push TWRP using
Code:
fastboot -i 0x1949 flash recovery openrecovery-twrp-blaze-2.1.1.img
and it returns: sending 'recovery' (5568 KB) but nothing ever happens.
I have tried draining the battery and recharging it completely. I have been able to get into recovery before by tapping the power button but don't seem to be able to do it anymore.
adb doesn't work at all. I should mention I am on a mac so KFU didn't work for me either.
I promise to be more careful in the future, can someone please help me save my kindle?
Try omitting the "-i 0x1949" from your command and flash it again.
EDIT: While you're at it, download TWRP again and confirm its md5 checksum before flashing it again.
md5 is ok, I tried without the switch as well still nothing

What recovery did you use to flash CM9 in the first place? What happens when you try to boot into the system?
I'm starting to recall some people having problems with the mac version of fastboot. Do you have another OS available just to compare things?
in my case the commands only return "is <waiting device>"
I had CWM I believe it's still in there somewhere. But I can't get to it anymore. Sometimes I think CM9 is going to start up because I do get the splash screen but it just goes on for like 15 minutes then the kindle restarts and goes back to the yellow triangle of doom.
EDIT: No unfortunately all I have is the mac

I hope you weren't using Hashcode's CWMR...
In any case, I believe I've seen another user struggle with fastboot on the mac. You might be having the same problem, but I can't find that thread. You might want to look into building Ubuntu Linux on a USB stick and try running that on your mac. Otherwise, you'll have to wait for someone who's used those tools on the mac to chime in here. I've never played around with it.

I have no idea which CWM I have. I couldn't find the mac fastboot thread either, I guess I will just put it away for now until I get access to a pc.
Looking above there is a good chance twrp sent I'm pretty sure now all you need to do is reset your bootmode
fastboot oem idme bootmode 4000
fastboot reboot
Do you try use factory cable? If not, let factory cable and run command
fastboot -i 0x1949 boot twrp-blaze-2.0.0RC0.img

Not to just sit here and tromp on your toes chamnv but the title of this thread is "kindle stuck in fastboot mode but wont accept commands" my impression of a factory cable is that it puts you in fastboot and secondly above he has attempted to send a new recovery why would he then send an old one?

[ISSUE] Kindlefire bootloop

I was trying to root my kindle today and decided to use the kfu.
I installed the drivers etc and started the kfu
http ://i.imgur.com/qNQgD.png
This is what the screen looked like, so i pressed 1
and then i pressed 2
http ://i.imgur.com/aAHRM.png
and the window said sending something and the kindle rebooted.
but now its stuck at the kindlefire logo screen. and anything you do in the kfu says it cant find the device.
i tried to use the firekit hoping it would fix the issue with the normal_boot script but all it does is hang at "waiting for device"
I know i probably did something really stupid, but if anyone could help me fix this i would be very grateful.

i tried :
Getting out of fastboot mode
To get out of fastboot mode, make sure the bootmode is set to something other than 4002 and reboot the device. The examples below will set the bootmode to normal and reboot the device.
With the stock bootloader...
Code:
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
but adb and fastboot don't recognize that a device is plugged in, in device manager it shows as Android Phone, Android ADB Interface
Hardware ids show
USB\VID_1949&PID_0006&REV_0100
USB\VID_1949&PID_0006
i have no firefirefire, or twrp and am on unrooted stock 6.3 if that helps.
Disconnect the KF from the computer
Make sure the KF is off by pressing and holding the power button for around 20 seconds
Issue the first fastboot command and it will indicate that it's <waiting for device>
Connect the KF to the computer and it will turn on automatically
The first fastboot command should get sent to the device as it goes into fastboot mode
Issue the second fastboot command to reboot

The fastboot executable you are using does not recognize the "-i" switch... notice it's not listed under options.
Download KFU and use the fastboot in that distribution.

What is the process to flash back to stock on a KFHD8?

Title says it all. I have the .img backups. Gotta send it in for a warranty replacement.
Thanks in advance for any help.
I've never done this but verygreen's thread http://forum.xda-developers.com/showthread.php?t=2017562 has instruction at the bottom.
Where it says:
Code:
fastboot flash boot /path/to/mmcblk0p10 -i 0x1949
What specifically needs to replace the /path/to portion? It says to remember where I put the .img files (I keep all of that in a specific desktop folder).
The path of the images is C:\Users\My Name\Desktop\Kindle Fire Resources\New Backup Images\stock-recovery (for instance)

Start with the Kindle off.
Open a cmd window like when you did the 2nd-bootloader install. Enter:
cd "C:\Users\Your Name\Desktop\Kindle Fire Resources\New Backup Images\stock-recovery"
fastboot -i 0x1949 flash recovery stock-recovery.img
(here your PC will wait for you to connect your Kindle via USB. Once it powers on, the fastboot command will automatically place the Kindle in fastboot mode and begin to run.)
(once that is done enter the next command)
fastboot -i 0x1949 flash boot stock-boot.img
(and finally)
fastboot -i 0x1949 flash system stock-system.img
(this command will take a long time unlike the first 2 which complete fairly quickly. next up, we need to clear out your user data and cache -- including sdcard. enter: )
fastboot -i 0x1949 format data
(then)
fastboot -i 0x1949 format cache
(and last)
fastboot -i 0x1949 reboot
If all is well this will reboot the Kindle into a brand new Amazon start up screen.
NOTE: I'll have to double check the format commands as I'm typing this from memory.

Ah, I didn't realize it was as simple as changing the directory and running the commands, I thought I'd have to reference the specific location. Thanks so much for your help.
For some reason it's only going into fastboot for about three seconds before turning off. Ever seen that before?
EDIT: It's also doing this when I attempt to boot it up or plug it into the charger. Has a good charge.
EDIT2: Later, plugging it in leaves it sitting on the Kindle Fire screen.
This is after flashing the boot.img failed. Am I stuck?
This is odd behavior. Normally it will sit on the fastboot screen for quite a while.
Do that screen showing "fastboot" actually come up? Or does it show the Yellow logo and then stop?
Not really stuck. All of the commands you're using are for fastboot mode which doesn't require a full Android OS.
Just need fastboot mode to work.
EDIT: What are the sizes on your stock-*.img backup files?

Recovery: 8,192
Boot: 8,192
System: 907,264
Recovery and boot flashed, but then it randomly turned off. I unplugged the Kindle (which had already given the Windows dismount sound when it turned off). I ran the flash system command, plugged the kindle in when instructed, and it turned off after a couple seconds of flashing it. Now it does that every time you put it in fastboot - display for a couple seconds then go away. I've got it plugged in and sitting on that KF screen for now, hoping maybe it just needed some extra juice or something.
FYI - I actually had to do TWO of these. The LCD cracked on one, and Amazon sent this replacement. The cracked LCD device restored just fine. The only exception were those wipe commands. They didn't work, but it booted into stock recovery and asked me to wipe, and it's good to go. Back in the box and ready to be shipped. This device (replacement for the cracked LCD) has a faulty power button, which I suspect may be part of my issue. Replacement number two arrived less than an hour ago.

[Q] Kindle Fire 2 Boot Loop PC wont recognize

I have a KIndle Fire 2 that is in a boot loop with white and orange logo constantly flashing on and off. I rooted it and was trying to load CM on it. I have a fastboot cable but that does nothing. PC does not recognize it anymore. I opened case up looking for reset button like the KF1 has but could not locate one. Is this fixable?
The problem started after the OEM Recovery command was sent:
Step 3: Use fastboot to apply exploit files and reboot into recovery With the device powered off: connect your FASTBOOT USB cable(if needed) to the Kindle which should cause it to power on and enter "FASTBOOT" mode. Issue the following commands into your command/terminal window on your PC 1 at a time. (if you don't need a fastboot cable then power on the device after entering the 1st command below)
fastboot -i 0x1949 flash bootloader otter2-u-boot-prod-10.2.4.bin
fastboot -i 0x1949 flash recovery otter2-twrp-2.6.3.1-recovery.img
fastboot -i 0x1949 flash boot otter2-freedom-boot-10.4.6.img
(if using a fastboot USB cable swap to a normal USB cable before entering the next command)
fastboot -i 0x1949 oem recovery
If all has gone well, then your device should now be in recovery.

Does fastboot find your device ? Use fastboot with getvar command to check if you device is recognized with fastboot.
If ok, try to flash the boot.img
You will find some useful tips here
http://forum.xda-developers.com/showthread.php?t=2271909
the fast boot cable does not put the device into fastboot and my PC doesn't even recognize it so how would I be able to issue any commands to the device
Where'd you get the cable from? I have heard cases here and there on the forum of people buying a fastboot cable that didn't work because it was just an regular cable being sold as such. I recommend the blackhat adapters myself.

OK so my pc does not have to recognize the KF in device manager for a proper fastboot cable to work?
Yes it does, you plug a fastboot cable in and it should show up as either a otter2,jem, or Tate device depending on the model, if it shows up as a android device bridge or something of that nature then the driver is already installed. Without a driver you can't interact with a device.
Edit: wait if you meant did the kindle need to be showing up already for the cable to work then the answer is no, the cable itself is what puts it in fastboot mode so the computer can detect it.

[Q] No fastboot/ADB unauthorized/TWRP loop = Bricked?

Hi all,
I apologize in advance, but I was unsure if there was another thread my issue would best be posted. I have a kindle hd 8.9 32gb that is now stuck in a boot loop at the twrp (2.8.3.0) splash screen (after installing the new Candy5 5.1.1 rom). The rom installed fine and ran perfectly the 1st time, but upon the next device restart it entered the recovery loop and never gets past the splash screen. The kindle itself is recognized by my pc while the screen is looping, but adb shows the device as "unauthorized" and of course with the looping issue I am never prompted to enable. With the 8.9 and no ADB, I also am also unable to enter fastboot mode. Any thoughts or suggestions, or am I bricked with the only possibility being a direct e-MMC restoral? *my soldering kung-fu is extremely weak*
Thanks in advance for any answers!
I have the same problem as you. I updated CM to 12.1, perform a factory reset and I got stuck on twrp screen which is blinking...
Possible Solution
I did something similar but with latest CM nightly rom and got stuck in the twrp recovery mode as a continuos loop, but mine was detected with the status "recovery" via adb;
Check if your adb /fastboot drivers are correctly installed and your not pluggin your kindle to a usb 3 port, then try this:
adb reboot bootloader
It will order the kindle to reboot in fastboot, after that you can just reflash the kindle to its original state with the fastboot commands from your backup.
Dont forget to erase the userdata, cache and all that stuff, you can do it with kindle firstaide
After that just redo all the process of rooting and install a Custom Rom.
Note: I got stucked on a loop of the kindle fire logo, cuz i didnt erase the userdata, but I was able to enter fastboot after the restore, thats why i suggest you delete the cache and other stuff
EDIT: Nevermind. Managed to resolve the issue by booting into fastboot mode, erasing cache and userdata using SR Tool from the KFHD_SRTv1.3.5 and then sideloading the ROM and GAPPS. I lost everything but it means i do not have to buy another KFHD.
Really grown attached to it, especially when the guys at Cyanogenmod keep on releasing updated OS's every year or so, making my tablet feel new every time.
Good work fellers.
I have a Kindle Fire HD with the CM12.1 ROM installed. After installing a nightly i did a factory reset from within the OS and it is stuck in a bootloop occasionally flashing on the teamwin splash screen.
Have i bricked my system or is there a solution.
I posted here because it appears that the op and myself have the same issue.
I tried ADB method but when i use the command "adb device" it shows as unauthorized so it will not allow me to run the adb shell or reboot command.
Any solutions will be much appreciated.
Hi to all
I have the same problem with twrp blinking after a factory reset on cm 12.1 ... I tried adb or fastboot commands (with KFHD_SRT_v2.1 or latest android sdk tools) but I cannot see my device. Consider that I installed adb drivers on a win 8.1 pc with 2.0 and 3.0 usb ports and I am using the standard cable included in the kindle fire hd 8.9 package.
Where I am wrong? A fastboot cable can solve the problem? Sorry for this question but I read many threads and there are different opinions about that...
Thanks in advance for any help.

When it's in the TWRP bootloop, the device should be in adb mode, so you can flash recovery, erase cache, etc..
I'd start off with a "adb erase cache", and that should get you past the TWRP bootloop.

I'm in this same situation... BUT, I finally got into TWRP and was starting to restore the ROM, but then my battery died... while i was in TWRP recovery.
Now my device won't power on (won't get to the Kindle Fire boot logo). I can't adb or fastboot, since the device won't power on, even when I plug it into the computer. I've tried charging it overnight, hoping that would help.
Nothing.
Do any of you Android gods (@Hashcode) have anything else I can try? Anything in the Android SDK that might help and at least allow the device to accept a charge?
Thanks!
Same problem
I'm in the same situation as the OP. Unfortunately, my device is unauthorized in ADB and since I'm stuck in the TWRP loop, there's not much else I can do. I wondered if it was perhaps the drivers causing the issue, so I fuddled around uninstalling and reinstalling to no avail. One thing to note is I'm using Windows 10, not sure if that could be causing any issues.
adb devices - Unauthorized - Amazon Jem- TWRP swithed to Cyanogen Recovery
I have similar issue. I have a kindle hd 8.9 16gb.I had 2nd boot loader installed with TWRP recovery. One day, I rebooted at it and it rebooted into cyanogen recovery for some reason (after installing the new CROM 5 5.1.1 rom). The rom installed fine and ranOK the 1st time, but upon the next device restart it entered the cyanogen recovery loop which has some options i.e. 1. Reboot system 2 apply update, wipe data /factory reset 3. wipe partition, 4. wipe media 5. reboot to bootloader ( fast boot mode)6. Power down and 7.view recovery logs,. The kindle itself is recognized by my pc while the screen is looping, but adb shows the device as "unauthorized" and of course with the looping issue I am never prompted to enable. adb devices results into xxxxxx ( some number ) unauthorized. I have tried all the options. No. 5 takes me to fast boot mode. but I can’t go any farther. The boot loop is driving me crazy . Can anyone help me? Thanks in advance.

when in fastboot mode, hook the kindle up to a PC with a terminal/command prompt (also make sure the kindle drivers are installed if you're running Windows) and enter fastboot -i 0x1949 oem idme bootmode 4000. you should see successful text on both the kindle and your terminal after running that command. if that's true, just do fastboot -I 0x1949 reboot afterwards to reboot the kindle.

No, that's a separate issue. What I would suggest right now is for you to download the bootloader, freedom-boot, and TWRP 2.8.7.0 from Hashcode's thread, reboot to the bootloader from CM recovery, and flash the files as directed to in step 5. However, don't power off the kindle - it's already in fastboot mode, so there's no need to turn it off and tell it to reboot into the bootloader. Also, ignore the post warning about flashing the freedom-boot image - we're only using it temporarily.
Once you have the files flashed, reboot into recovery. If you're in TWRP, go ahead and flash CM or another ROM. Just avoid booting into system until you do so.

Hi Monster 1612! Thank you very much for helping me out. Please bare with me b/c I am a newbee. Should I download File no.2 & 3 from Step 2 or more. Can you explain a little more about "reboot to the bootloader from CM recovery" . If I do that it takes my device to fastboot mode. What is flash the files as directed to in step 5. How to flash the files in flashboot mode". Is there a link about this? Are you talking about codes in the box in Hashcode's thread? I really appreciate your help.
The files and instructions should be located in this thread.
As for booting into fastboot mode on the kindle, this should be easy - in its current state, it just boots into Cyanogen Recovery, right? Anyway, you just need to choose option 5 in that recovery menu to enter fastboot mode.

I downloaded the bootloader, freedom-boot, and TWRP 2.8.7.0 from Hashcode's thread, reboot to the bootloader from CM recovery, and flashed the files as directed to in step 5 from Hashcode link.. Didn't power off the kindleas at it was already in fastboot mode as you said. Once I had the files flashed, rebooted into recovery. Wow, it rebooted into TRWP recovery mode. with 8 buttons (reboot,advance,mount,setting,restore backup,isnstall, wipe). I was so happy because of your help. Then I did the stupid thing. I rebooted probably into the system. Now My device is stuck in Kindle fire Yellow/white logo. Now ADB command works but adb devices dont bring anything ( waiting for devices). The driver is installed but my PC does not see it device manager. I lost fastboot mode too. I was so close sir because your help. I remember you telling me to flash into a ROM and not boot into system.
That makes me a real noob. Now please help me if you can. What is next? Is thre still a hope?

The bootloader should still be responsive regardless of what's been flashed onto the kindle. Go ahead and completely turn off the kindle (hold the power button down for 10 seconds till the screen turns off), and then open a terminal on your PC. Type in fastboot -i 0x1949 getvar product , and plug in the kindle when you see <waiting for device>. After a few seconds, the kindle should be in fastboot, and the prompt should have outputted something like "jem-pvt-prod-04". Now repeat that flashing process again, and type fastboot -i 0x1949 reboot when done. Press and hold the recovery key (the one closest to the camera) until you're in TWRP, then flash CM or another chosen ROM from TWRP.
Happy to help!

My friend , you are becoming a saviour. Have you got any donate button for support? I would like to contribute. This time I am not going to rush. Want to make sure I undestand everything. What is [/I] before / after fastboot -i 0x1949 reboot and fastboot -i 0x1949 getvar . I hope its not any part of command. BTW, I dont see any key near the camera ( recovery Key?). I have kindle fire HD 8.9. This has power key and up and down volume key.

So far, I don't have a donate button - I'm worried about its legality, cause I'm not 18 for at least another year.
Anyway, the button we're talking about is volume up. It's the one closest to the camera, and the boot partition's programmed to boot into recovery when this button is pressed and held during initial boot (I.e.: when the Kindle Fire logo appears and changes from orange to blue). The fastboot flashing process I described above goes like this:
1) Power the kindle off completely, type fastboot -i 0x1949 getvar product, plug in kindle when prompted.
2) Kindle should boot into fastboot, and "jem-pvt-prod-04" or similar text will appear.
3) Flash TWRP, freedom-boot, and the 8.1.4 bootloader as you did before.
4) Type fastboot -i 0x1949 reboot when you're done flashing, then immediately press and hold volume up as soon as you see the kindle fire logo. Keep holding until you're in TWRP.
5) Flash a ROM, as well as gapps if desired.
6) Profit
Hopefully, this clears up any confusion.

However, I cant understand for some reason, it did not boot into TWRP recovery and went back to Kindle fire logo. I did press the volume up key As soson as KF yellow logo came in but it stayed yellow. . I can turn it off by pressing for 10 secs. Now what my young friend?
