[Q] Halfway through rooting, recovery failure flash; boots but inconsistent charging - Kindle Fire Q&A, Help & Troubleshooting

Environment: OS X 10.7.3; started with stock KF 6.3.1. Added 0x1949 key to ~/.android/adb_usb.ini, confirmed adb working with adb logcat. Plan was to root stock ROM first, get comfortable with the KF's behavior in that state, then eventually get over to CM9, as my Droid Incredible runs CM7 quite beautifully.
Started with procedure at http://forum.xda-developers.com/showthread.php?p=24129239 . Pushed fbmode successfully, chmodded and ran it, adb reboot successful. Continued with the following
Code:
[email protected]:~/development/android/kindleroot$ fastboot -i 0x1949 flash bootloader u-boot-firefirefire-1.2/u-boot.bin
sending 'bootloader' (211 KB)... OKAY
writing 'bootloader'... OKAY
[email protected]:~/development/android/kindleroot$ fastboot -i 0x1949 flash recovery openrecovery-twrp-blaze-2.1.1.img
sending 'recovery' (5568 KB)...
...and everything stopped. Waited there for about 10 minutes before giving up. Eventually powered down by holding power button and then pushed it again to start up; got yellow firefirefire triangle. That screen suggested pushing power to go into recovery; no dice.
I thrashed a little with fastboot oem idme bootmode commands until I got it to successfully reboot. Current boot sequence displays firefirefire triangle for a few seconds, then goes to the 'kindle fire' logo screen, then boots to working stock OS. The first time this happened and several reboot cycles thereafter, it would not charge via stock charger or Mac USB and LED would not light; after another few reboot cycles, it suddenly decided to charge with stock charger and LED lit orange. I'm not inclined to experiment any more until I get (a) some knowledge and (b) better than 36% charge. ;-)
I assume I've got a borked recovery. Question is how to fix and continue on my happy rooting way. Help much appreciated.

What a relief it is to see such a detailed description of someone's problem. Thank you.
When you turn the device on and see the yellow triangle, hold the power button until it turns orange and release. Does it boot into recovery?
I'm sorry if that sounds like a stupid question but you can never assume anything here.

No, good question, and thanks very much for the help. I tried that several times and was not able to even get the power LED to turn orange, which seemed odd to me. Should have put that in my initial post. Thinking about it, I may not have unplugged the USB cable during those cycles; perhaps that caused it not to respond to the power button.
So I just tried it again. Rebooted by issuing 'adb reboot' and, this time, unplugged as soon as screen went dark. At FFF triangle, held power button until LED went from green to orange. At this point, LED stayed orange and the backlight changed intensity two or three times while still on FFF graphics. The kf logo then came up briefly, then the KF rebooted entirely. On that boot cycle, I touched no buttons and it appeared to go normally (FFF triangle, then kf logo static, then kf logo with shimmering animation, then stock lockscreen). Charging from AC continues to work.

Download twrp 2.1 again and check the md5 before reinstalling with:
fastboot flash recovery /path/to/recovery.img
...and see if that gives you a better result.

Reinstall worked this time -- I issued the command immediately following adb reboot and it flashed successfully as soon as FFF started up. This time the 'fastboot oem idme bootmode 5002' command just yielded '...' though, and 'fastboot reboot' just yielded 'rebooting...'. It's as if the fastboot USB connection just dies for some reason if you don't keep feeding it data.
So I shut down with held power button, pushed power button to boot to FFF screen, held power button to orange LED, held my breath, and TWRP popped up. Steps after that all went perfectly, I Dropboxed Superuser.apk and Root Explorer over from my Inc after the reboot, and we're in business with hot hot root action.
Thanks very much for your help -- it's nice to have somebody who's seen all the weird failure modes around in case I bork something.

Yeah, after changing the bootmode in fastboot, "fastboot reboot" doesn't work.
I'm glad to see you worked it out though.

[Q] Need Help - Bricked Kindle Fire

I got this kindle fire that I am trying to fix for my kid. I don't know what firmware was in. The KF has never been rooted. We tried to call Amazon for a replacement, but since I didn't remember which email account was tied to this KF and I couldn't find the Serial Number either, I got stuck with it. If could make this device to boot one more time to see the amazon account or the serial number that will be great.
Well anyways, these are the symptoms. After lots of hours of reading about bricked Kindle Fires I decided to order a factory cable suspecting the problem was a low battery KF going into a 5 second loop. The process went good. I was able to flash FFF 1.4a and TWRP 2.2.2.1 by going into fastboot mode, but the problem is that the KF does not want to start in recovery mode, nor in normal mode.
At this point, I think I can rule out a battery low problem, but I am not sure.
No matter what I do, I cannot enter to adb mode, and this is the real problem I don't seem to find an answer. If there was a way that I could upload the firmware from fastboot mode or a tool that forces recovery mode.
As I said this KF was always stock until today that I tried to unbrick it by installing the FFF and the TWRP. The TWRP never started.
As I said earlier my only objective at this point is to recover the serial number or the account email associated with my KF.
Question 2, how can I revert to the stock bootloader if everything else fails?
Any suggestions, links, ideas will be welcome.

I hate to ask this question but do you know how to access recovery by using the power button to get the boot menu then selecting recovery? If you are using the boot menu to attempt to access recovery and its not cooperating it`s possible that points to a broken bootloader or a broken recovery. When you flashed both fff and twrp did you see that it sent and physically wrote each one? maybe explain how you flashed them so we can see if a error was made there. What level do you believe the battery is at? Possible it could be playing a role in your present issue.

I have done a lot of experiments with my SGS2 about installing ROMS using ODIN or CWR, backing up my own images and making backups. Most of the work I do though is in CWR. I haven't dealt with TWR yet. I also installed ICS on my HP Touchpad. So, even though this is the first time I deal with the KF, I already some experience working with ROMS and images.
Back to the process. I installed the FFF using the Kindle Fire Utility. The KF was forced to fastboot mode via the factory cable. At first I could see on the KF splash screen with the black and orange logo, and now the KF is booting using a Black and Blue kindle fire logo with 1.4a on top. At the bottom of the splash I see instructions of the bootloader selector indicating to press the power button and select the mode that I want to boot. Either Normal Mode or Recovery Mode.
I flashed the TWRP 2.2.2.1 in fastboot mode using my command prompt by putting this code:
Code:
fastboot -i 0x1949 flash recovery [path]\openrecovery-twrp-2.2.2.1-blaze.img
I was following the instructions on this guide.
http://forum.xda-developers.com/showthread.php?t=1638452
I got stuck on step 3 after attempting to boot into recovery mode.
I can select which boot mode I want to go, but none of them work. I only get on the bottom of the screen saying Booting... and then the KF shuts down.
I suspect the battery had a good level of charge, but I can't tell for sure.
Thanks for everything.
Download TWRP again, check the md5, reinstall, and post whatever error messages (if any) that are in your command window here.
In the meantime, enter the following command and let me know what happens after you reboot.
Code:
fastboot oem idme bootmode 5001
fastboot reboot

All commands were successful.
When I'm doing instead of the fastboot reboot is to remove the factory cable. Shutdown the KF by holding the power button. Then I connect a regular USB cable. The KF starts the boot process. It enters the first splash screen. Then it moves to booting, but the booting fails. The only thing that I see is that the button light turns from green to yellow and then it shuts down. And the boot process starts again going into a boot loop.

Thanks for reading my thread.
If upon rebooting, the result is the same after changing the bootmode, it is possible the bootloader isn't working properly. If that's the case, flashing a new bootloader (with md5 verified) might not work, but it's worth a shot.
If that doesn't work, you should be able to change the bootmode to USBboot (4003) and use Firekit to replace the bootloader, but that's speaking theoretically. I've never tried it so I couldn't tell you whether it would work or not. But then you could always pull the back cover off the device and use the shorting trick to use Firekit in USBboot.
If installing a bootloader with the Firekit doesn't work, you're likely looking at a hardware issue, and there's not much we can do about that.

I'm at work. I am going to try number 1 when I get home.
One more question, how can I revert the KF so when the it boots it shows the original orange white logo?
Thanks for everything.

If you have any questions about using Firekit, don't be afraid to ask.
Get your device working properly before attempting to revert the bootloader back to stock. Contrary to what you may think, the custom bootloader is much better for you in this situation.

I suspect your battery is still depleted because it still sounds like a 5 second boot loop. Try this hold the power button down till it`s off and plug it to your pc for a few hours to see if you cannot get some power to your battery.

I think that would be the case if the device just rebooted. The OP is saying the device shuts down when FFF starts to load the operating system (Booting...) or recovery, which is why I think it is either the bootloader or some hardware issue.

I have nothing to lose. This KF is already bricked. I can certainly try anything. Which cable do you suggest I use? the Factory cable or the USB cable?
I think I answered my own question now. Using a regular USB cable puts the KF in the bootloop. I will use the factory cable instead. I shut down the KF, put the factory cable connected to my computer and the KF. Right now the KF is in the KindleFire splash screen waiting for fastboot commands of for me to use the button to tell it which mode to boot. I will leave it plug overnight.
Thanks for replying on my thread and trying to help me.

I posted a video in utube of what the KF is doing, so you can see what I'm seeing.

Thanks for coming back several times to reply on my thread.
That looks like your battery. From what I can tell, the device is just rebooting, not shutting down.
Unplug the device and hold the power button to perform a hard shutdown.
Plug the device in (it should power up on it's own) and hold the power button to shut it down again.
Leave it plugged into the computer until sometime tomorrow and try again.
Same thing I was thinking 5 second bootloop Thank you the video was very helpful to see just how its acting. Use stock cable to charge not factory.
OKay. I'm glad I came to check the thread one more time before going to bed. I removed the factory cable and put the regular usb instead. The KF was rebooting. I shut down the KF by holding the power button without unplugging the cable. Now the KF appears to be shut down, but the cable is still plugged. The yellow light does not appear as it normally would if it was charging though. I don't know if this is normal.

[Q] Kindle Fire powers on, flashes and shuts down

I have come into my possession a Kindle Fire 1st generation. When I got it, the youngster said it was “hacked for the Amazon App Store”… and the battery was dead. I traded an older laptop for it. I put it on a charger for a day or so and left it. It would boot to the “Stock” logo for several seconds, then the backlight would go slightly brighter and it would shut off.
I started reading up about some of the power-on issues around the web. I found most of my answers on “xda-developers.com” for my TF101 so I gravitated here.
Here is what I’ve done so far:
1. Acquired a factory cable... SO useful.
2. Flashed FFF v1.4a and TWRP v2.4.4.0
3. Played around with fastboot.exe commands -update, flash, erase, getvar, reboot, help
4. Flashed a stock bootloader and recovery… trying to get it to charge.
5. Disassembled and tested battery voltage… 4.10VDC on a 3.7V battery. That sounds good to me.
6. Tried the firekit boot from Live-USB. Won’t stay powered on.
Right now, I’ve flashed the FFF 1.4a and TWRP v2.5. What happens is, in normal boot, the fire boots to the FFF logo (White &Blue) goes to “Booting” and the power switch LED gets slightly brighter, then the backlight goes slightly brighter and the whole thing shuts off. If I push power to go to recovery, the fire shows “Booting.” Then, the power switch goes orange, then it goes off, then the whole thing shuts down. I cannot do any ADB commands because the Fire will not stay powered on in that mode. The factory cable keeps it powered on, but I’m stuck with fastboot.exe commands in that mode.
I do not have a stock charger. I’ve been using my charger from my TF101 and a cable from my phone or the factory cable. I’ve been futzing around with this thing for a few weeks and would like some input. I haven’t found an identical issue so I’ve decided to create a thread.
I’m wondering if I have a bad gate on the memory chip… I’ve seen desktops and laptops shut down with bad memory in the past. I’m reasonably savvy with a command prompt and not afraid to crack a box.
Hold the power button until the device shuts off completely. Plug it in to your USB cable power source (not the factory cable), and let it power on automatically. Immediately after it starts to power on, hold the power button to shut it off again. Let it charge in this state for a few hours and try to boot into recovery again.

Thank you Soupmagnet. I've done this and let it sit for a weekend... sorry I didn't mention it before. With a voltage reading of 4.1, I think I have a full charge (by the way, it doesn't drop over a day or so). You can be assured that I've tried most everything before posting. Please be gentle if I didn't state it previously
One of my issues is I can't get to anything on the fire itself. Even with the factory cable, is shuts off if I choose to continue... hold the power button and choose recovery, normal, reset boot mode. Is it supposed to be able to go to recovery when the factory cable is connected? It only stays powered if I leave it at the FFF logo.

Fastboot -i 0x1949 flash recovery c:\KFU\recovery\twrp.img.
This is after I renamed the v2.4.4.0 file to old_twrp.img and downloaded the v2.5 that I found last Friday. Previously, i'd used the KFU. Last week I played around with flashing different bootloader and recovery to see if I could get it past the FFF or stock. At this point it's a challenge to get it to go further than FFF.

Use fastboot to flash this to your system partition and see if you can boot normally.... http://d-h.st/NzN
Perhaps it is hardware, not software
Just had a very similar issue. Turned out to be stupid simple.
Use spudgers to gently take the back off the case (a small flathead screwdriver should do the trick). then check the connection between the battery and the motherboard. In my case, my daughter had dropped it enough times that the connection was not all the way out but not enough in. This caused the exact behavior you are describing. Took me 2 minutes to fuss with once I got motivated.

[Q]bricked kindle in usbboot mode.

I recently recieved this kindle as is from a friend and i was asked to fix it, i don't really have any information to go off of other that what i could gather. So far, it doesn't turn on/charge, in windows it's recognized as a OMAP4430 device only for a second or two, from there i tried using FireKit on ubuntu via usb. that gave me some success, after using usb_fix_parts_and_install_fff_twrp i saw the yellow triangle on the screen; however, the script seemed to stop with this:
waiting for OMAP44xx device...
sending 2ndstage to target...
waiting for 2ndstage response...
sending image to target...
Fixing partitions...
< waiting for device >
and won't progress any further. i'm not really sure what to do at this point since i feel so close and it would be a shame to quit now.
I've also tried using multiple USB cables and a fastboot cable, but none seem to be making a difference. so please if you know of anything that would help, it would be greatly appreciated.
You only have a small window of time to get everything through. When the usbboot script hangs at "waiting for device", leave the script running, unplug the device, hold the power button for 15 seconds, create the short and plug the device back in.
You may have to do it a couple of times.
Once you see the yellow triangle, don't shut the device off until you install FireFireFire1.4a while in recovery. You may have to use adb to push the .zip file to your sdcard first though.
Oh, ok thanks. i didn't know i still had to preform the short, since it was already in usb boot mode. anyway trying it now.
I'm not sure if I'm doing it correctly. I followed what you said and after shorting the device, and plugging it back in, it brings up the yellow triangle again. But pressing the power button doesn't bring me into a recovery and the script still says waiting for device
I should have clarified that a bit, but oh well.
Go ahead and reboot to try to access recovery with the power button. Sometimes when you reboot, depending on how everything went, the device doesn't come on again and you have to start all over...but you should be fine though.
=/ not too much luck there...maybe i'm shorting the cpu incorrectly, not sure. once the script hangs i unplug and power off the device, and essentially just any old conductive piece of wire should do and connect it to the point and the metal bar, right? i'm using a male to male jumper cable at the moment. While doing this i've noticed a couple times the kindle would power back on and display the yellow triangle but still no other responsiveness or progess in the script itself.
When the yellow triangle is displayed, do you have access to fastboot?
Try sending 'fastboot getvar product'
i guess not. it just sits at "< waiting for device >"
Try using a safety pin to make the short....that might help.
so slight update, it turns out i have no problem booting a firefirefire from usb, but from there it just refuses to initiate fastboot and ubuntu can't seem to recognize it. i thought it might have been a possibly issue with the specific version of FFF i was booting from, but so far 1.2, 1.3 and 1.4 all give me the same issue.

Make sure you have FFF1.4a and run your fastboot commands as root in Ubuntu.
so i just found out something interesting. i had a spare fully functional kindle that i put into usb boot mode with the shorting trick, and did all the steps, and fastboot was able to recognize it. i haven't done anything differently with the currently bricked kindle, but it just wont get past "waiting for device" when issuing any fastboot command. so at this point is there really anything i can do?

Stuck in weird power cycle/fastboot loop

Forgive me if I am not describing this in the best terms.
My fire was stuck at the kindle fire logo, it would load for 2 seconds to the kindle fire logo then turn off and boot to the logo once again, non-stop.
I plugged in my fastboot cable and it immediately booted into fastboot. While connected to fastboot I opened the Kindle Fire utility and under one option was the option to boot into recovery. My thought was, if I could force it to boot into TWRP I could fix permissions/wipe cache or something like that to get it working.
It immediately disconnected from my computer (the noise the computer makes when a USB is disconnected) then it went on connecting and disconnecting non-stop. The screen turned on to kindle fire logo, then to fast boot logo then went black, the entire time it is connecting and disconnected to my computer, making the connection tone then disconnection tone every other second.
I unplugged the kindle then held the power button for 60 seconds, this seemed to turn it off. I hit the power button again, while still unplugged and it shows the kindle fire logo, immediately followed by the fastboot mode logo, then the screen goes off. If i plug it into the computer it is making the connect/disconnect noise.
I feel like if I could get it to stay in fastboot I could use the recovery tool to fix it, but at the moment it is just cycling non-stop and cannot be connected to the computer.
Any ideas?
Thank you for any help you can give me.
FIXED
Okay, great news, I fixed it. After trying a combination of EVERYTHING I could find on the internet, a dozen programs and images. So, here is how I did it.
At the windows command prompt I entered the command: fastboot -i 0x1949 getvar product
this was while my device was constantly connecting and disconnecting, launching straight into fastboot. So the command did not execute right away, it would say < waiting for device >
While plugged into the computer, I held the power button for 20 seconds to shut off the device, then hit the power button to restart the device. The moment the device turned on, before it would power cycle, the command processed and the device would stay on, at the fastboot screen.
Downloading KFHD_SRTv1.3.5 I opened that program. Giving me options to restore the device. I did an ERASE CACHE AND USERDATA (Options 4), once that completed I did the RESTORE-FACTORY RECOVERY (Option 3).
I tried to reboot right here but it would AGAIN begin power cycling through fast boot.
I went back to my command prompt and issued the command: fastboot -i 0x1949 reboot
The device rebooted to the kindle fire screen and DIDN'T go to fastboot, it DIDN'T power cycle. It took a few minutes to load, but when completed it loaded the stock amazon application.
This took me a couple hours, I tried a lot of different methods and a LOT of different boot.img, recovery.img, system.img. I downloaded 15gb of files trying different thing. This worked for me.
Good luck all.

Kindle Fire (1st Gen) stuck at boot logo after setting fastboot mode.

Hi. Long time lurker, but finally found myself in a pickle. So now I'm asking for help.
I have a first get Kindle Fire that I figured I'd experiment with after getting a new Kindle HD 8. It has OS 6.3.4 and has been stock until just now.
I already rooted it and was then going through the process outlined in this thread:
https://forum.xda-developers.com/showpost.php?p=54124313&postcount=3
so that I could add TWRP. But, after the step "Step 5: Forcing Fastboot Mode" and entering "adb reboot", the Kindle rebooted without the animated logo as the instructions said it would... except it stayed that way.
And, it's still that way. Any adb command I enter returns "error: device not found". I tried the Kindle Fire Unbrick utility, but it also couldn't find the device, even though it finished the attempt with the message that it's now unbricked - except, it's not. Even my Windows 10 PC throws up an error when I try to reconnect the USB that there's a device error.
It's not in a boot loop - it's flat stuck. I can turn it off by holding the power button for about 15 seconds. And I can turn it back on, and I've tried entering adb commands as soon as I do turn it on to see it if takes, but it doesn't. It just sits there displaying the "kindle fire" logo.
I was going to try to load regular android on it, but now that seems out of the question.
Is there anything else I could try? I will try letting it drain the battery, and then plugging it in again, but any other suggestions would be appreciated. Anything else I need to provide, please let me know.
Thanks,
-Joel

When it's in fastboot mode, use fastboot commands, not adb
Sent from my sailfish using XDA Labs
Thanks,
The instructions were not clear on what to expect at that point, and I assumed it was stuck. It didn't occur to me to just keep going.
So I did, and it responded as it was supposed to. When I got to "fastboot -i 0x1949 oem idme bootmode 4000", it returned
FAILED (status read failed (Too many links))
finished. total time: 0.031s
But the "reboot" command took and got the white and blue. It flashed a bunch of times but finally got it to boot with the normal white and yellow logo. I think part of it was that the battery had gone down since I last posted. I'm now recharging it before going further.
Still, thanks. I guess it wasn't stuck or bricked after all.

I watched several videos, and I think I started yours at one point, but between my 8 year old running around saying it's almost midnight (it was new years eve), and then trying to get him to go to bed, by the time I came back to this, I may have lost track of what I was watching.
Moral of the story, do this kind of thing without interruptions...
I did re-watch your video all the way through and I see that what happened was normal.
Still, there was that error trying to reset the bootmode (I didn't get what you got), otherwise, it still works and re-boots fine now. Even went into Recovery.
Next thing is trying out a new rom.
Thanks again.
MY DEVICE IS ALSO STUCK!!! After doing the fastboot reboot it gets stuck with the lifeless bootscreen and doesn't do anything from there, I've also tried to use the set boot mode but it hangs on waiting for device
