Ok, I updated, seems like it worked, didn't come across any problems. Now, that's the last time I'll bug you, I swear, I just need to make sure I do it right, last time I had to deal with a bricked kindle I really freaked out, I don't want this to happen again if I don't have to. In the part where you explain about how to flash a rom you say this:

So, what do I choose if I want to wipe everything exactly? I choose factory reset, but is there something else I need to wipe? Cache or something...? Sorry, I'm not really a noob anymore but I'm not on the expert side either when it comes to roms... :(
[7" Kindle Fire HD Android Development] :
The ROM should wipe the system before it flashes. Just swipe to factory reset, flash your ROM and Gapps and then wipe cache and dalvik. Then reboot and your up and running.

Good to hear you didn't have any issues updating TWRP. I didn't either but many did because of the selinux switch. It wiped everything and backups would not flash. Because of that I always recommend pulling a backup off to a pc (or upload to Dropbox) so pics and other unreplaceable items can be recovered.
[7" Kindle Fire HD Android Development] :
Ooooh, I see! Okay, that seems easy enough, I think I can manage doing that!

Yeah, it had no issue with TWRP, everything's running just fine. I actually found an app that saves my app data on dropbox (has a few more cloud options, that's just the one I like best) and I mostly care about my saves in games since it's so difficult to keep them otherwise. I don't take pics or anything with my kindle's camera, more or less whatever file I have in it came from my pc so I have a copy there. :D

Although if I have to be honest, I'm not quite sure how a backup works. I couldn't make one with your instructions (that's why I skipped it after a few tries in the first place, I probably missed something when typing in CM cause it always came up with errors) and I'm not quite sure how the backup in TWRP or apps like Titanium Backup work. I don't get what they backup and where, and how exactly I can restore it. Perhaps I should post a question about that in the Q&A forum sometime... :rolleyes:

Soft brick???

Hi guys,

So I ended up flashing the 7.2.3 bin file update to "system" since I was getting a bootloop at cm11 and wanted to start from scratch. I installed it, but now I am just getting a flashing screen with the orange Kindle Fire logo. It comes on, then goes off (this happens many times), then completely stops at the logo. It cannot go into recovery, and fastboot doesn't work either. Help!
[7" Kindle Fire HD Android Development] YuriPan:
You probably bricked it, sounds like what happened when I first tried to flash a rom (actually while installing the bootloader). I think you need to follow the instrictions to get into fastboot mode and restore your kindle, but wait for someone more experienced to tell you for sure. It's only happened to me once, I had to use a fastboot cable to fix it...
[7" Kindle Fire HD Android Development] brittoking:
Yes you bricked it. And yes you need a fastboot cable which is not the standard cable that comes with the kindle.
[7" Kindle Fire HD Android Development] r3pwn:
Technical reason as to what happened:

When you flashed the update file, it removed the stack override file and the second bootloader, but left your recovery image, which fails signature verification, perfectly intact. This is easily fixable, given that you have a fastboot cable. All you need to do is flash your recovery partition with a stock recovery, because you currently have TWRP installed, which, as stated before, fails signature verification, putting you into that loop. The reason you didn't have this happening before is because the second bootloader and the stack override help bypass signature verification, but you removed those, so.... Lol. PM me once you get a fastboot cable (if you don't already have one) and I'll be able to help you fix it. :)
[7" Kindle Fire HD Android Development] green_reaper:
thank you

this is great, i did everything but i have run into an issue. every time i boot up i get a trebuchet has stopped messaged. i have no clue how to fix this. as soon as i even get to the lock screen this occurs. it is preventing me from accessing any apps i cannot even go beyond the messaged

Factory cable to downgrade?

Sorry if this question has been asked and answered but the thread is getting pretty long.

This guide says no fastboot cable required, which is great because I don't currently have one, but then when it links to the tool to downgrade, a factory cable seems necessary? Unless I misunderstood?

It might be irrelevant anyway because I'm very late to this and have 7.5.1 firmware. However, I did root with no special equipment so handy. Is it still possible to get the 2nd bootloader?

Basically I just want to know if I need the cable. Cyanogenmod is cool. This kindle has been collecting dust a long time. That doesn't mean I want to brick it but the likelihood of me moving forward is less likely if I need the cable.

Thanks a lot!

BTW--this is one of the most detailed guides I've ever read. Awesome job!
[7" Kindle Fire HD Android Development] xWolf13:
A regular cable is needed. Maybe you misunderstood of entering fastboot mode with the cable. No need unless your get the "Red Screen of Death" which is like a softbrick. Installing Cyanogenmod is easy as you already have root. You can use this application here to flash the needed bootloader, recovery, ROM + gAPPS. Click this link for more information
[7" Kindle Fire HD Android Development] KLit75:
Thanks for the reply. Before I read this I tried downgrading but stopped because I couldn't get my Windows pc to connect via adb. The kfhd was rooted with Mac which is my main computer. I rarely use Windows (mostly because my pc is garbage)

I'm assuming after reading what you just linked me to that the software will flash even though I have the latest firmware. That's really good news but I'm not sure I have the correct drivers installed? Kindle appears under devices but Windows fails to find the drivers. Amazon directs me to Windows media player.

Well I guess it doesn't hurt to try. But if you can enlighten me on exactly which drivers I need and where to download it would be helpful. Thanks again!
[7" Kindle Fire HD Android Development] xWolf13:
So in my understanding you want to flash Cyanogenmod correct? If so, you do not need a computer to use that application. Simply download ES File Explorer on the Amazon App store and download the needed files. Since you are already rooted, you can do it all straight from that application I have linked you on.
[7" Kindle Fire HD Android Development] KLit75:
I was just coming to that realization after watching the video. Exactly what I wanted to hear! Got ES file installed already. I'm going to try it. Thanks again!
[7" Kindle Fire HD Android Development] xWolf13:
Feel free to PM me if any more help is needed. Good luck!
[7" Kindle Fire HD Android Development] KLit75:
Thanks! Got twrp but struggling so far w cm. I couldn't adb push sd so I copied to local storage (I assumed that is the equivalent because just copying to the root where android file manager takes me I couldn't find it) I wiped factory reset then install cm and it fails. Should've checked error. Does it need to be flashed with more zips?
[7" Kindle Fire HD Android Development] xWolf13:
Probably just a bad download. Don't forget that you need gAPPS also. Flash CM, the the Google Apps and you should be fine. Do not forget, since you are coming for Amazon's OS to wipe System, Data, Cache, and Dalvik.
[7" Kindle Fire HD Android Development] YuriPan:
Ok, quick question. The latest versions of TWRP support f2fs, am I correct? How can I change my kindle's format to f2fs? :confused: I can't seem to find any guides for KFHDs anywhere. Thanks in advance.
[7" Kindle Fire HD Android Development] wolf45801:
yes I just got me a fire hd and somehow it updated to 7.5.1 I got it rooted with no problem. what im wondering is all I need to do now for the second bootloader and twrp is use fireflash and flash the 7.2.3 bootloader and second bootloader and twrp?
[7" Kindle Fire HD Android Development] see3po:
i cannot root or 2nd bootloader

What tool did you use to root? I got mine about a month ago and it's on 7.5.1. cannot root using QEMU method. I get "/system/bin/sh: cannot create /data/local.prop:" error.

I also cannot complete the 2nd bootloader steps in this thread because I keep getting "/system/bin/sh: su: not found" in any command involving "adb shell su"
[7" Kindle Fire HD Android Development] wolf45801:
I did the root with restore bin4ry
[7" Kindle Fire HD Android Development] JediFonger:
i've used both qemu, the video and the bin4ry restore. the bin4ry restore doesn't have clear directions. when it says press 1, i got more selections. of which i tried both. the major issue is that i just dont have su and permission gets denied and there's no way around it.
[7" Kindle Fire HD Android Development] LumberjackZac:
Kingroot works for this flawless.

My question is if this boot loader strap on has been updated to support 7.5.1
[7" Kindle Fire HD Android Development] JediFonger:
i did finally manage to get it all to work... what a major pain. the directions and links to files are all out of date on multiple threads.
[7" Kindle Fire HD Android Development] kcuffel:
These directions here and everywhere aren't very specific. Does this work with 7.5.1 in terms of the 7.2.3 bootloader flashing? Also are there any mirrors of this?

[7" Kindle Fire HD Android Development] Devo7v:
I followed the instructions exactly as they are written and downgraded from 7.5.1 to 7.2.3 successfully. Then I used the files in the following post to flash the 2nd bootloader and TWRP. Hopefully this helps.

Hoping for some help. I want to go back to stock. First I downgraded twrp to 2.7.0.0 (earliest I could find) then I transfer 7.41 to SD. Followed hashcodes guide & wiped system . now 7.4.1 zip is gone. Can't connect adb, nor mtp. I can connect fastboot but really I just need to get hashcode's prerooted zip onto the device. Any ideas?

If starting over by flashing freedom boot & twrp via fastboot is the only option I can do that too.

Btw--im hearing kingroot now works so ideally I'd like to keep root with the latest stock version if that's now an option.
[7" Kindle Fire HD Android Development] kcuffel:
You don't need to downgrade. I did it on the latest 7.5.1 completely issue free.
[7" Kindle Fire HD Android Development] kmodek:
I have 7.5.1 too and can't find anything about how to root from the beginning except bad videos with bad links and no instructions. My KFHD was rooted but I couldn't EVER get the Play store to work so I reset it to factory and want to start over but can't seem to find any beginner instructions. Honestly, I rooted it when I first got it in 2012 and it was just dumb luck that it worked that time. I don't really know what I did to get it rooted and I'm not really clear on all the jargon related to it. I don't have any interest in different ROM's or having to mess with the code part. I just want to be able to get the Play store on it and get it to keep working.

Can you give instructions on how you did it since it's been updated to 7.5.1?

Thanks!

I can in a few days. Out of town and have none of the info in front of me at the moment! But I'm sure we can get ya setup!

I've just flashed CM 11 on my Kindel Fire HD with 7.5.1.

The root procedure was the same*. I have downgraded AFTER the root (before installing recovery and bootloader).

*Pay attention using Bin4ry, beacuse it changed: you don't have to choose option 1, beacuse it isn't the same of the guide. I used option 4 ("New Standard Root - tnx Ariel Berkman", like the guide above).

Hi, I rooted my kinlde fire hd 7 version 7.5.1 and installed KFHD7 TWRP 2.8.3.0.img. After rebooting my Kindle starts but stuck in bootloop. Tried to go into fastboot but Computer won't recognise it. Any solutions before buying Fastboot cable?

I think i bricked myself!

I know I'm supposed to look though all the reply's before asking but there are 66 pages. I installed the stuff but now I cannot get into recovery. When I press the volume up button I believe it should become blue, but it crashes before it does anything. It shows the orange kindle logo for five to ten

seconds but then a small line appears randomly on the screen and the kindle reboots. Do I have to get a factory cable? I used flash fire and rebooted and now this has started. Does anyone have any idea how to help me? I don't have a factory cable neither do i have the facilities to make one.

M'y Kindle fire HD is rooted, adb and fastboot are ok on the pc and the mac, but " fastboot -i 0x1949 getvar production doesn't work

IT keeps on waiting device.

I'm using a standard usb cable.

I can acces fastboot with adb / reboot bootloader, but even in fastboot mode, the fastboot command do not work. What amis I missing ?
[7" Kindle Fire HD Android Development] crazynapkinman:
This has happened to me as well... I may have already posted this same thing or something somewhere else. I do believe we both need the "factory cable" a.k.a. "fastboot cable". 9.99 on amazon.... fml :eek:

I did everything it mentioned and it booted to TWRP great. I then rebooted system from TWRP and it is stuck on same bootloop as you.

---------- Post added at 05:41 AM ---------- Previous post was at 05:35 AM ----------

Go into device manager with kindle in fastboot. Right click the device. Click update driver. Click browse. Then "select from a list" option. Choose "fire device" and click ok.

Will work after that.
[7" Kindle Fire HD Android Development] crazynapkinman:
Bump. Anyone??
[7" Kindle Fire HD Android Development] crazynapkinman:
Hello?? Heeeeelp me somebody!
[7" Kindle Fire HD Android Development] :
Yes, you need a fastboot cable. You can get a cheaper one here.

Once you're in fastboot, flash the latest twrp image and reboot to recovery by doing:

fastboot -i 0x1949 flash recovery kfhd7-twrp-3.0.2-3-recovery.img
fastboot -i 0x1949 reboot oem recovery

Then pull the cable quickly after it reboots so it doesn't enter fastboot again. Flash a working rom in recovery and you won't be stuck in a bootloop.
[7" Kindle Fire HD Android Development] Dishe:
This is crazy, and dangerous. This thread is outdated, and I'm not clear on how to handle working with 7.5.1 now. It looks like more than a few of us have stumbled and messed up our devices. Maybe we can convince the OP or a Mod to edit the first post?

I'm trying to read through it and make sense of it all... I'm having a hard time. Is the fastboot cable needed to do any of this, or is it just for those of us that bricked during installation? What is the current method to do this on the latest firmware (without downgrading and without fastboot cable)?
[7" Kindle Fire HD Android Development] crazynapkinman:
Follow the op. Just make sure when you boot to TWRP you have the custom rom on your device and ready to flash. If you flash TWRP and boot stock rom, it will bootloop.

So follow op, ensuring the rom is on device storage (I left mine in download folder on device). When you boot into TWRP first time, make sure to flash custom rom (followed by gapps and supersu, if you want Google play store and root) THEN reboot.

Again, HAVE ROM AND GAPPS ON DEVICE (AND FLASH THEM) BEFORE REBOOTING OR YOU WILL SOFTBRICK!
[7" Kindle Fire HD Android Development] manicpanic:
Thanks worked great.

PROTIP:

Make sure to revert to 7.3 before starting the process. You'll red screen on 7.5

Not sure if this is the proper place for this, but thought I'd try since this is a TWRP thread for the HD7.

I've had an old 4.X ROM on my KF for a few years now, and figured it was time to upgrade. I already had root/recovery from that install. I successfully flashed a Resurrection Remix ROM no problem, but came across another one I'd like to try. Did the usual wipe routine, and flashed the new rom + gapps and supersu (per the ROM instructions.) After reboot, the old ROM (RR) was still on the KF. Thought I missed a step so I ended up trying again, making sure I wiped system. When I wiped system going from 4.x to the RR ROM, I remember accidently hitting the reboot button and TWRP warning me that I was going to boot without an OS. I wiped system again, but this time it doesn't give me a warning if I try to reboot. I'm thinking TWRP isn't really wiping....is this a possibility? Did switching to MM affect permissions needed for TWRP? My KF is up and running at least, but I can't flash another ROM.

[7" Kindle Fire HD Android Development] Duncan Idaho:
So after several experiments, I was able to make and pull the recovery files from the tablet, my issue now is in regards the fastboot commands, I can get into fastboot mode, but I have no way to make use of the commands because I lack the drivers. By any chance anyone here has the fastboot drivers for amazon kindle fire HD 7" 2ndgen ?
[7" Kindle Fire HD Android Development] Duncan Idaho:
So I am back with a few more questions, it seems I can't quite find a good rom to install over stock, I tried CR DROID and it flashed correctly, but after one hour and thirty minutes, it never went anywhere, I am now attempting to use this Cyanogen mod and all it keeps doing is updating app's and rebooting. Is this natural?

Regarding going back to stock, apparently something in the instructions went awry because the twrp backups that I made got wiped, still I have two images of the kindle on my desktop PC stock boot and storck recovery. Can I use these images to get back to stock?

The tablet isn't bricked, I can access TWRP thanfully, its just that I can't seem to boot into the newly flashed rom. Yes I did wipe system, dalvik and cache.

Bravo, bravo, bravissimo!

This tutorial worked like a charm. I had a Fire HD 2012 lying in drawer for like 4 years and decided to throw it away. But then I thought to upgrade it and give it to parents. And it works!

Check your version here: https://en.wikipedia.org/wiki/Fire_HD I have 2012 7'' model with 7.5.1 OS.

Raw procedure (I had not special cable, so needed root to fastboot) - read the whole first post for all details!!!:

1) root with Root Many Android - option for device is (3) OLD

2) downgrade to 7.2.3

3) root again

4) wifi was not working so install fireflash with

adb install fireflash11.apk

5) install all images

Some links are dead, you can google for files or use these links:

Same config as you, just a couple of corrections. For step 1 the "old" option is "5", not "3'.

The micro google apps kept failing with not enough space error, nano worked.

I also had to not join my wifi after downgrading to 7.2.3 as my Kindle decided to download and install the update back to 7.5.0 while online. I kept the Kindle off WiFi and instead used adb push and install commands to install/copy files/apps needed for flashing.

Not sure what I am missing. I have a rooted 7.3.1 Kindle Fire HD that I want to load custom recovery and 2nd bootloader on. I am going through the guide and getting stuck early on and not sure if I go any further. In part 4 you mention how to make sure the identity of the product by opening CMD prompt and typing " fastboot -i 0x1949 getvar product". When I do this I do get the waiting for device line, but when I plug in the Kindle it just powers it up normally? ADB recognizes my kindle when typing adb devices and I have used adb and fastboot for my HTC phone, when I type fastboot or adb in the cmd prompt it runs through the list of commands available and I have installed the usb drivers. What am I missing as to why I can't get into fastboot? Do I need the factory cable for this? Any help is much appreciated!
[7" Kindle Fire HD Android Development] seokhun:
That's just if you want to get fancy. In actuality, you don't need fastboot at all to successfully complete the guide. Seeing that you know for a fact you have a Kindle Fire HD 7", you can continue to Step 1: Rooting.

Your fastboot drivers don't work, not for the device. Go ahead and open Device Managers if you're on Windows, or however you get to the list of drivers on the computer. With the device plugged in, uninstall the ADB drivers and the Kindle's driver on the computer. Then unplug the device and reboot the computer. At this point, do a reboot on the device, then turn ADB on, and plug it back in. your computer will now reinstall the drivers, then try to use fastboot.

If this doesn't work, I'm out of ideas, except do a fresh installation of Android SDK, which is the most painful thing in the world, but it's worth trying. Do note that you don't need fastboot or ADB to complete the guide.

Okay. Using the Windows setup (keeping it simple) I have also tried the Kindle Fire Fiest Aide Tool and selected option 9 to test fastboot status. Wasn't able to find the kindle. I have looked under the Device manager and can see the kindle there. When clicked on it has "Android Composite ADB Interface" listed, nothing else. Is that OK?

If I don't *need* to run or use fastboot for this process then I will try using the Fire flash app once my KFHD is charged. Also notice that KF First Aide option 39 offers the same process but not sure if that version of TWRP is ok to use... will prob stick with fireflash
[7" Kindle Fire HD Android Development] seokhun:
Under Device Manager, uninstall the Kindle driver and/or the ADB driver. Then reboot both the computer and the Kindle and plug it back in. This will trigger a fresh reinstallation of those drivers to minimize errors.

Stick to manual with clear instructions other than something you have no control over. A lot of people reported problems with that tool.
