Kindle Fire utility not working

My kf was previously rooted at 6.2.1. I haven't played with it much considering it kind of did what I wanted, although it lost root a while back. I am now trying to reroot after getting the latest 6.3 upgrade. I downloaded the 0.95 KFU but it won't run. It starts, but the window disappears after about 5 seconds. I tried 0.91 and it went through the whole cycle but of course didn't work. I have downloaded everything I know to do and .95 won't run. I even dis the whole SDK thing all over again. Any help is appreciated.

Are you running the latest version of Java and do you have the newest SDK? Also try Kindle Fire Utility v.0.9.4

My suggestion, from seeing countless members running into problems with the KFU, is root your device manually. It's a little more work but there's less chance of failure IMO.

thanks
I got it working. For whatever reason, I ended up replacing the older KFU version which was located it the root of the main drive with the new version. The new version was in the desktop. I have no idea why it wouldn't have worked, but as soon as I moved it, it ran, and there was no issue with getting rooted. Thanks for the help.

After Root -> sluggish Kindle with flashing logo
Hi,
I root me Kindle Fire v2 (v10.4.6) to, with the software KFFirstAide but I got several problems.
1. software can't find and install busybox.apk
2. software shows me the message "all fine" but the kindle is sluggish and the boot logo is always flashing every 2 or 3 sec.
The Software-Option to remove this problem doesn't work - i get always a error back.
Is there an option to fix this?
If i use the kindle option: factory reset, all works fine again but root is off.
....

Is it worth rooting the kindle fire? I've been thinking any doing it and flashing a rom
---------- Post added at 03:20 PM ---------- Previous post was at 03:16 PM ----------
One thing I like abt rooting is that it gets rid of the special offers which get annoying after awhile

Is it possible to change the original ROM-Version 10.4.6. directly to CyanogenMod 10.1.3? ( cm-10.1.3-otter2.zip) or does I need a factory cable for a downgrade or some other fixes? My only experience with CM is a Samsung N7000

That's not a downgrade, the kindle doesn't run CyanogenMod by default. You have to install 2nd bootloader+ twrp to flash custom ROMs. Look here for info and make sure to downgrade the boot loader first, and I can't stress enough to check the md5sum of the boot loader when you download it, you don't want a hard brick from a bad download: http://forum.xda-developers.com/showthread.php?t=2100963

Full backup of one AFTV and restore on another
It's great to see that modstore was able to clone an AFTV.
I dont understand what modstore is saying here:
modstore said:
I'm not sure if anyone has tried backing up one Fire TV and restoring to another, but I just tried it, and all seems good.
Doing the restore though, changed the registered account to that of the backup. So I'm not sure if it would have been registered properly, probably not. But I changed it to the account I wanted it registered too, and all seems good now.

Changed what registered account? Does this mean that the new AFTV was setup to have the same amazon account as the backed up AFTV before the restore took place on the new AFTV?
I really want to be able to clone. It sounds like its possible, I just want to avoid the trial and error if possible. I'm sure others are interested in the procedure too.

Yes, from what he said that the registration info went over with the backup. If you want to clone machines, then this will work.
he didn't want to clone machines, so he had to put in the correct register info on the machine he put the backup on.

There might be a way to make it trigger the initial Registration page after doing a restore of a clone. I'll add it to my list and maybe come up with a special update.zip that will make it happen.

So if you have a FTV set up with xbmc etc you can make a direct copy of it into a stock FTV, thus cloning it as said above?

I've looked around and can't seem to find what to do. I've used adb before but have never ran into this issue yet seems so silly.
When I type "su" in adb shell i get this error "system/bin/sh: su: not found"
I've googled and all I can find is reinstalling the superuser on the phone... I'm trying to unlock the boot loader

You need root first. What fw are you on? If it's a rootable version, do that first and then follow the guides for updating here.

Yea figured it out. I'm on 1.3.0 this sucks. I'm trying to sell my amazon box to get a nexus player. Amazon has no idea how to run a home media center.

Thanks!

Guide from AFTVNEWS.
I got recovery to work everything was fine I could reboot from recovery back to recovery again (CWM) but after I did factory reset in CWM it gets stuck on amazon logo.
The reason I did factory reset was because of Error.7 in CWM I had that few times when flashing different roms on different phones/tablets
sometimes getting older cwm or simply factory reset would help.
So now it gets stuck on Amazon logo the keyboard trick to get back into CWM does not work anymore.
Anything else I can try before I call up amazon hoping they replace it ?

I can honestly say if you followed rbox's custom recovery install guide, used his recovery image, and made sure the md5 matched, you shouldn't have had any problems.
Out of curiosity, do you have an external hard drive plugged in?

Yea I did follow instructions correctly. And no I do not only had the usb keyboard plugged in so I could get into recovery.
Almost every device I rooted w/ custom recovery gave me Error 7 tablets phone etc.. I seem to have bad luck with that error lol.
Since I was on the very last step.. flashing rom -> getting error 7 grr

I think cwm still has some issues. It works fine for installing rbox's pre-rooted ROMs, but I can't backup my ftv. It always errors out.
Was this the first time you've gone through cwm install? Did you try installing one of his custom ROMs and then got that error? Did you verify that your recovery download went okay? Check the md5 against what's listed on the site.
I know it's a lot of questions, but I'm just trying to delve deeper to see what may have caused your error.

Yes sir everything was checked few times. Bunch of times made sure even file size is correct etc...
I did install recovery however at first when I had wrong firmware I installed via ADB SHELL then I Downgraded to unlock bootloader after I downgraded I installed recovery via adbfire I think newest version .17 however it was still the newest firmware of recovery anyway.... and yepp it was stock pre-rooted latest firmware that ends with "0" that did not require the fire tv boot menu.. but now I am thinking if I had the boot menu I could have got into recovery! so AFTVNEWS mis-lead me on this part... the bootmenu would be great on all firmwares actually.

I'm not sure about adbfire anything. I do all mine through Linux/android terminal/windows command line. The boot menu works on firmware 51.1.4.0. When it's sitting at the logo, have you tried connecting via adb, just to see if it initialized enough to poke around? (not sure if it works that way with ftv, but I'd try, regardless)

As far as I saw I could only connect via adb at least when in recovery mode.. otherwise it was a no go... anyways thanks for helping me out. I think there is no rescue in this situation by somehow fixing it. I mean just wanted to have few features like swap storage with a flash drive and have newest FW. But that's ok.
Thanks for your time!

Sorry I couldn't be of more help :/ the issue you'll probably see is that unlocking the bootloader voids any warranty with amazon.. So I'm not sure what amazon may or may not do for you.

About the possible Lollipop ROM for FireTV,is there a way to get the latest qualcomm Adreno 320 drivers like [email protected] from another device for flashing in proper FTV directories since it is meant for Lollipop?
I am hoping for the fix for Dolphin to be runnable and Reicast to no longer cause reboots,as well as better performance for things like Mupen64Plus AE.

Hello All XDA members,
I have a Kindle HD 8.9 and as the warranty passed off, at the same time Christmas is nearing...I decided to install CM KK on my sons kindle as i don't have enough money to give a present to my son.
I've done all that is given here : http://forum.xda-developers.com/showthread.php?t=2100963.
Problems I've faced are as the thread didn't mention to root I was trying some codes without that but some how figured that i needed root to proceed..Simultaneously rooted my kindle rebooted and then proceeded with the codes i.e backup of system img and all the steps that were given.
I has all the downloaded files in download directory so the stack push didn't work first then i moved all the required files to C> ADB folder and everything worked but before figuring it out i googled stack file push failure and came across a guide that has the stack push directory to data/temp (I see that this was later edited here)
However i retried with the push to the location that is currently mentioned now and it worked (So the stack file is at 2 locations now)
Proceeded with all next steps and stuck at flashing bin file in fastboot, realized the downloaded file was .bin.html i renamed it to bin and flashed
Everything was done as mentioned except something that needed to be understood and done by logical thinking like removing .html and flashing .bin.
After all this when the kindle was supposed to reboot it didn't and its completely dead now... I have done all that was mentioned and have said all the errors or misses that i has above ..now is it that the kindle is dead brick forever ?
I cant trust how can that be because i really know how cautious i was and i did almost every thing as mentioned..
Saddest part is that now I've messed up my sons kindle which i thought of Flashing CM KK and giving a little gift as i'm not capable of providing any gift now ..I've messed his kindle as well now
I'd be really glad and thankful if some one can help me out in this situation and recover kindle.
Again i'd like to mention I've done as mentioned please trust me and still have the image backups, i read that the back up can be reflashed but as there is no commuication via ADB or flashboot i don't thing that can be done now .
Why did this happen what can be possible reason ?

Sounds like you may have accidently saved a webpage instead of the .bin file, that's why it had the .html on the end. If you tried to flash this to the bootloader then unfortunately you have bricked it

It shouldn't have .html on the end. Check the md5 sum for the file and make sure that it is the same as it should be, you should ALWAYS do this when messing with the bootloader

Maybe you flashed wrong images.
I just went to the link of the guide that you followed in flashing a second bootloader and recovery. The instructions are for a Kindle Fire 2/ Otter2. Its a different device from the KF HD 8.9. So.... if you did flash the images from that link, it will lead to a bricked device no matter if you followed the instructions to the letter. Maybe you can sell it on ebay or Craigslist for parts. Just a thought...

I actually plan on doing this for a similar reason. My sons kindle battery life is appalling as it drains faster than before and charges slower, plus kindle updates are lacking badly and some things don't work anymore.
I hope you can fix it somehow.

As stated by Max above, if you flashed those images from that thread you linked to in your post, then those are the incorrect files for your device. and would have definitely bricked it! assuming you do have the FFHD 8.9 inch. but you still may be able to unbrick it. are you positive of which kindle device you have? if you are positive that it is indeed a KFHD 8.9, do you know which version it was on before you started the OP?

Edit : i tried to root kindle but was not able to, its on the highest or most up to date version of fire os as per amazon
I tried to root with restore by binary, cant see superuser in app drawer, able to see it in system/apps via root explorer
Tried to install firefire.apk it shows no root & root explorer doesn't rename system apps to .bak.... So i believe i cant root..
Please @11fan help me out now i need only cm on kindle thats fine for me.......
I'd be gratful to you for the help

Let me see if I got this correct, you sold the bricked kindle with the incorrect images on it on craislist? You Bought another kindle off eBay that has been reported stolen/lost? That sounds like some of my luck! So you got another kfhd 8.9? And you are for sure!? If so, go to about tablet in settings and see which version its currently running, also turn ON USB debugging and set it to allow 3rd party app installs in security settings, then get adb and fastboot working and we will go from there.

yes the lag is known issue after/when trying to root using some of the ways posted! if you can get through the lagg long enough to get an app on it i would recommend using an app called keyrootmaster you can get it here http://download.apks.org/?server=14&apkid=com.zhiqupk.root&ver=1.3.6 this is what i used and several other posters i know of, THE ONLY BAD THING IS the app is written in Indonesian language, BUT it works and after about 3 taps you got root! if you are going to CM or some other rom it shouldn't matter about the language anyway as all of that app will be gone and superuser is baked into CM anyway. see if you can get that app, get it rooted and let me know and i will try to help you get TWRP and CM installed.

Help please! Fire phone without an OS and stuck on amazon logo

Hello,
First of all, Thanks for this great community. It has been helping me with my S4 for a long time.
Almost a year ago, I bought a fire phone for my younger brother. Today I tried to install the Custom Rom CM11 (which I successfully did), but, among the files in the proper thread, are 2 more files, the Google apps and also, a "flash wipe out". I did this in the end, expecting that just cleaned everything without touching the OS. Huge and novice mistake from miself. After almost 5 hours of looking for a solution, I realized that I don't have an OS and can only enter to "Fire phone recovery mode". I have downloaded almost 5 or 6 stock firmwares that are available to donwload here in XDA. Tried to download the OTA for an unlocked phone from amazon and tried to upload it to the phone via ABD tools. In the end, I always get the same errors: Not-signed and can't install it in the phone.
I'm going to be honest: I'm desperate.
In conlcusion:
1) No OS in a fire phone.
2) No custom TWRP.
3) I just have recovery mode
4) Been trying to install through ADB tools without any success the stock OTA update (the last one, since I had the 4.6.6 version)
Anything that can help will be well received.
Thanks in advance

Hello,
Have you tried ADB sideload when you go into your phone's recovery? And if you did, what did it say when you tried installing it? Try using this to sideload your phone.

Thanks for your answer @mechasnyper but I have tried that out as well
Hey, thanks for the answer. I really appreciate the time for doing it.
Yes, I have tried the ADB Sideload. The phone it's identified through the CMD (I get to see the serial) and then try the ADB Sideload. It doesn't work with bin files. It says unable to load. I tried also with the zip files that are posted here in the forums, being able to load then at 100% but the cell phone says "invalid signature", and for this couldn't install it over the fire phone.

Yes, I have tried the ADB Sideload. The phone it's identified through the CMD (I get to see the serial) and then try the ADB Sideload. It doesn't work with bin files. It says unable to load. I tried also with the zip files that are posted here in the forums, being able to load then at 100% but the cell phone says "invalid signature", and for this couldn't install it over the fire phone.

Try sideloading using this file. https://www.androidfilehost.com/?fid=24052804347783512 I found this somewhere else and this is the file I used when I screwed up my ROM installation.

When I get home I'll try using that file that you have posted.
I'll update the results.

Success?

Sorry for the delay. Been talking with centurylink because since yesterday I have no Internet service (Answering from the phone). No, no success at all.

Your need free RAM on computer bigger than .bin size.

Hey, thanks for the answer.
I'm doing it on my laptop that has 8 Gb of ram. Just in case, I'm going to try it on my brother's laptop that has 16 gb of ram to test this out. But I doubt this will make a difference, since I've tried already many .bin files (all of them are unable to load an their size its 1.2 GB max. Many zip files as well where I have obtained 100% load but the firephone aborts the installation due to signature verification failure.

This is really strange. I have screwed up installing Cyanogenmod onto my phone, yet I was able to revert back to the stock ROM with just the stock recovery. I will have to look more into this. I will post again soon for updates. Have you wiped the data and cache?
EDIT: I am not sure if this will work, but try using this bin file. http://androidhost.org/o120v

@lordofra
Try (with quotes)
adb sideload "full_path_and_name_of_the_bin.bin"
