Hey guys,

I am getting the fancy blue logo etc.. but then it boots into "Safe Mode" and my Kindle looks almost the same as it did, i.e. no "Install" options etc. Any ideas?

Update: Nevermind... I never knew which button was volume up or volume down since it isn't labeled and I'd never changed the volume before! :) (It's the one farthest away from the power key!)

I don't have a factory cable or fastboot cable, is there a trick to get into fastboot?
[7" Kindle Fire HD Android Development] AmrBanawan:
I think this command should do it

adb shell su -c "reboot bootloader"

Check your kindle's screen i thinks there should be a SU request

Re: [BOOTLOADER] Install 2nd-bootloader for Custom ROMs on KFireHD 7"

There's an app on here somewhere called KFHDBackup that will boot you into fastboot.... But for the life of me I can't find the thread. So... Here's a db link. http://db.tt/ccpFCVWo
[7" Kindle Fire HD Android Development] tdo722:
Thank you very much. I was able to go into fastboot and did these steps:

fastboot -i 0x1949 flash boot kfhd7-freedom-boot.img

fastboot -i 0x1949 flash recovery kfhd7-twrp-2.3.3.0-recovery.img

fastboot -i 0x1949 reboot

The first 2 commands completed successfully so that means I got the freedom and twrp flashed. But now I'm in a boot loop. I guess the last command "fastboot -i 0x1949 reboot" kicked it out of fastboot mode and now I am totally screwed. How do I get into TWRP so that I can flash the 7.2.3? I tried holding down Volume UP but that didn't work. Thanks in advance.

Re: [BOOTLOADER] Install 2nd-bootloader for Custom ROMs on KFireHD 7"

You holding down volume up at the Blue & White kf logo screen for at least five seconds? ¿

Not to sound redundant but you are pressing volume up and not volume down?... Away from the center is up. People have made that mistake before.
[7" Kindle Fire HD Android Development] tdo722:
Thank you for your fast response. I don't even see the blue & white kf logo screen. I see regular white & yellow kf logo screen. Also, I do know the the volume UP button quite well because I use it all the time playing games everyday. :)

Were you able to fix your issue? I am having the same problem as you. I'm stuck in a boot loop and mine is still white & yellow not blue & yellow. I don't have a factory cable. Where did you buy yours?
[7" Kindle Fire HD Android Development] persano:
hey, i m having a lot of bootloops and installed all fine, i dont know why, i can use fastboot but cant reset to boot mode 1
[7" Kindle Fire HD Android Development] tdo722:
I think we are having the same problem. I never installed safe strap before. Maybe that's why? I do not see blue logo at all. After completed STEP 5, my kindle is now officially dead. I don't have a factory cable. I will order one and see if I can set the boot mode 1 and see if I can see the blue logo. If I don't see the blue logo, then I will call amazon and get a replacement as my last hope. Will they reject if they found out I was tinkering with hashcode's stuff?
[7" Kindle Fire HD Android Development] persano:

[7" Kindle Fire HD Android Development] Krsmqn:
Re: [BOOTLOADER] Install 2nd-bootloader for Custom ROMs on KFireHD 7"

If you are not seeing the blue and white logo then you did not install the bootloader correctly. You should now obtain a factory cable if you cannot achieve communication via adb with the kf.
[7" Kindle Fire HD Android Development] persano:
i see the normal and then the blue one, reboot and again and launch twrp, why ??????????
[7" Kindle Fire HD Android Development] Krsmqn:
Re: [BOOTLOADER] Install 2nd-bootloader for Custom ROMs on KFireHD 7"

When the blue starts, hold down the volume up button for at least 5 seconds... Then wait about 60 seconds.. You should see TWRP soon. If not, reboot and try again.

Persano, you seem to have no rom to boot into. Do you have a backup? If so, restore it with twrp.
[7" Kindle Fire HD Android Development] persano:
if i flashed it, i will try thanks :D

other thing, i cant flash my system img, how i can check if fastboot work well or how i can fix it ?

it is normal that in twrp mount system isnt checked ?

---------- Post added at 10:26 PM ---------- Previous post was at 10:19 PM ----------

Re: [BOOTLOADER] Install 2nd-bootloader for Custom ROMs on KFireHD 7"

This installs a second bootloader which also installs TWRP (Team Win Recovery Project) so you can backup and recover your device. You also will have the ability to install custom roms in the future (like Kinology).

[7" Kindle Fire HD Android Development] Krsmqn:
Re: [BOOTLOADER] Install 2nd-bootloader for Custom ROMs on KFireHD 7"

Ok... I will try to keep this short and simple. I can't explain it too technically, maybe Hashcode will, but the original bootloader on the KFHD7 was locked down tighter then a preacher's daughter, and the best way around it was to do just that: Go around it! So Hashcode gave us a second bootloader that loads after the first and it is essentially unlocked. That allows us to add programs to the Kindle that work before the rom boots. (correct me where I'm wrong devs)

TWRP is a recovery program that allows you to backup your rom, and recover it if it ever fails. You would only need a factory cable if your bootloader(s?) become damaged.

TWRP also allows you to flash (install) custom roms and other software that isn't in the traditional .apk format. (again, correct me if I'm wrong devs).

Basically, TWRP is your mulligan. If you follow Hashcodes instructions carefully, you shouldn't have any problems installing it. Every one should have a recovery installed.

Hope that helps.
[7" Kindle Fire HD Android Development] bdeatha:
Thanks!

thanks alot for the feedback.you mean i can upgrade the default OS of my kindle fire from ICS to JB if i have a TWRP in my kindle?am i right?what arre the custom roms like for example?..and what are those other softwares that is not the traditional apk files?you mean if the system fails i can recover it by using the TWRP?sorry... i really dont have an idea about this...i was just a newbie when it comes to modifying kindle. :confused:

Re: [BOOTLOADER] Install 2nd-bootloader for Custom ROMs on KFireHD 7"

So far there is only one custom rom for the kfhd7, Kinology. Do not attempt to install anything else or you will mess up your kindle. If/when someone can build a custom kernel for this device, then custom roms will be made available. Kinology is a hybrid of the original kf rom. So it can run using the original kernel. CM10.1 though would need a different kernel.
[7" Kindle Fire HD Android Development] conalt:
Re: [BOOTLOADER] Install 2nd-bootloader for Custom ROMs on KFireHD 7"

Jelly bean is not available for our kindles. I would recommend you stay away from installing this second bootloader and different roms for the moment. Out of all the kindle mods it is the most advanced and risky, especially if you are unsure of what it all means.

A rooted kindle with Google apps and the play store make for a perfect setup. If you haven't done that already, I would start and learn from there.

Another link explaining twrp:

The 2nd bootloader is a bit more complicated to explain, but understand that it is a technical necessity to boot third party operating systems and that most ”normal" tablets don't require it. But Amazon makes things unnecessarily complicated...

Re: [BOOTLOADER] Install 2nd-bootloader for Custom ROMs on KFireHD 7"

Another noob question regarding "kinology" and second loader etc. I am completely new to this rooting game and accessing root control , but here is my question- I've got root, playstore and stuff and am wondering why do I need kinology is it just to give new interface and back up or something else ?. Now the only answer I can come up with is "cause I can, I'm a bloke and we like to mess with stuff especially when there is a warning that it could go wrong!!! It's like a challenge right? I'm guessing the answer is if I don't know what I want it for then I probably don't need it, can some help me here with a real reason?

Cheers for a practical honest response

[7" Kindle Fire HD Android Development] soupmagnet:
The Kinology ROM just adds some basic Android JB/ICS like features while still keeping most of the stock OS interface. If you like the stock Kindle Fire interface the way it is, then don't mess with it. If you want to try it and have done the appropriate amount of research, you understand the risks, and know you what to do in case you run into trouble, then go ahead.
[7" Kindle Fire HD Android Development] bdeatha:

Thanks again.you mean installing this 2nd bootloader with kinology is a must to our kindle fire hd 7" to help us fix when our systems in trouble?am i right?where can i find this kinology and how to install it in step by step procedure?i hope there is a tutorial for this one that i can follow so that my kindle will not gonna get in trouble cause its too hard to fix and it will takes a few weeks to finish.sorry for the bad english.im not good in english.hope you understand what im trying to say :D thanks again!
[7" Kindle Fire HD Android Development] Krsmqn:
The second bootloader & TWRP are required in order to install kinology. You do not need to install kinology. You can if you want a rom that is close to the amazon original but works flawlessly with 90% or more of Gapps.(google apps) There are also some other fixes which allow for easier installing & better performance of non amazon apps. The kinology rom can be found here.
[7" Kindle Fire HD Android Development] bdeatha:

thanks again.you mean i have to do the procedure at the first page of this thread first before i proceed to the kinology rom thread?have you tried this already?is there no hidden issues after doing this on my kindle fire hd?i just want to make sure that everything will gonna be fine after doing the procedures.thanks again for the helped.
[7" Kindle Fire HD Android Development] Krsmqn:
Re: [BOOTLOADER] Install 2nd-bootloader for Custom ROMs on KFireHD 7"

Yes. The procedure at the beginning of this thread must be done first. Then Kinology can be installed. Yes I have the second bootloader and twrp installed with zero issus. And I have Kinology installed as well with zero issues. Go slow, read everything twice, double check.

[7" Kindle Fire HD Android Development] ursus101:
Good evening / night / morning everyone!

The story starts here. In short, I messed up my build.prop file. As a result, kindle OS is not loading anymore. I am stuck at kindle logo animation. The goal is to install custom recovery and then fix build.prop.

I tried to follow instruction in this thread to install the 2nd bootloader & twrp recovery. Unfortunately, I cannot get it to work. Obviously, I am doing something wrong. Hope you can help. I got a fastboot cable, KFHD7, Windows 7, kindle usb drivers are installed.

Here is what I do.

KFHD7 is turned off and disconnected from computer. I type command in terminal:

fastboot.exe -i 0x1949 getvar product
<waiting for device>

Then I connect the device using the fastboot cable. The device instantly switches to fastboot mode (I see Fastboot Kindle Fire logo on the device). In terminal I get:

product: Tate-PVT-08

I disconnect the device and turn it off.

Since kindle os is not loading, I cannot complete steps 1, 3 and 4 from here.

I type in terminal:

fastboot.exe -i 0x1949 flash boot kfhd7-freedom-boot.img
<waiting for device>

Then I again connect the device using the fastboot cable. The device turns on and switches to fastboot mode. In terminal I see:

target reported max download size of 1006632960 bytes
sending 'boot' <8145 KB>...
OKAY [ 2.818s]
writing 'boot'...
OKAY [ 0.678s]
finished. total time: 3.508s

While device is still connected I proceed with two other commands:

fastboot -i 0x1949 flash recovery kfhd7-twrp-2.3.3.0-recovery.img
target reported max download size of 1006632960 bytes
sending 'recovery' <8145 KB>...
OKAY [ 2.815s]
writing 'recovery'...
OKAY [ 0.681s]
finished. total time: 3.507s

fastboot.exe -i 0x1949 reboot

After the last command the device reboots. Since the device is still connected to the computer via the fastboot cable, it switches to fastboot mode. I manually disconnect the device and turn it off by pressing the power button for ~15s.

When I turn on device by pressing the power button, I get a regular white & orange "Kindle Fire" logo. It blinks about every 3 seconds -- it seems that the device simply reboots all the time. If I keep the "volume UP" button pressed while I turn on the device, I get into exactly the same situation.

I can still get into fastboot mode with a fastboot cable. I tried the steps above many types. I am getting the same result all the time.

Any hints what might be wrong? All I want at this point is just get into recovery. Any help is highly appreciated!

[7" Kindle Fire HD Android Development] Hashcode:
I'm guessing you are now on the 7.3.0 software which patched the bootloader.

If you'd like, you can try flashing the u-boot.bin from the 7.2.3 update via fastboot and then try again. Be VERY careful with this command and make sure you are applying the right file as if this is done incorrectly, you will hard brick the device. (We get the ability to fastboot partitions via the bootloader -- if corrupted that goes away).
