Hi,

I currently have kfhd8-freedom-boot-8.4.3 and kfhd8-freedom-boot-8.4.6 on my Kindle 8.9 and I have fire flash v1.1 installed. This was about a year ago I have not touched it since.

I am trying to upgrade and hashcode mentioned that I should make sure that I have the latest book and twrp installed. I've check and they are kfhd8-freedom-boot-8.4.6 and kfhd8-twrp-2.7.0.0-recovery.

Is it safe to use fire flash to install them? Any instruction?

Thanks

Hi,

I had trying to upgrade from 4.3 to 4.4 ROM. I read that I need to make sure I have freedom boot 8.4.6 and TWRP 2.7.0.0. So I tried to upgrade, using fireflash, put both boot and recovery in, and choose install scripts (first option). Then reboot.

Now it's stuck withe the blue Kindle Fire logo.

I can get into TWRP recovery. But not sure what I should do next. Can I check if freedom boot is installed correctly? Should I continue to flash the 4.4 PAC-man ROM?

Thanks

-- EDIT

I read the first post again.

[12/09] kfhd8-freedom-boot-8.4.6.img (USED ONLY THE FIRST TIME -- .zip files will have their own boot.img's from now on):

Does it mean I should not have tried to flash the boot img? Should I just go ahead to flash the ROM zip?

Thanks

Just a quick note for those that are having trouble manually flashing a TWRP update. Once you have the image on the root of you internal SD card > open the FireFlash apk > scroll down to RECOVERY PARTITION > click on the NOT FLASHED button directly below it > now scroll down to the TWRP image you want to flash > click on it > now scroll all the way down to FLASH,INSTALL SCRIPT located under EXECUTE. Now your TWRP is updated. Note: Don't tick anything else along the way.

Edit Note: FireFlash is only usable on 2012 KFHD 7 and 8.9" Using it on any other tablet will brick it.

Does anyone have all the files at the beginning of this post? Goo.im is permanently offline so i can not get them anywhere. Thank you for your help

boredmug · May 19, 2015

Same thing.. Can't get any of the files to actually do this..

astupka · May 21, 2015

I was unable to download the files due to goo being dead, but I found them copied on a chinese site (baidu). They had the same checksum (be SURE to md5sum after downloading just to be sure they weren't modified). If you use the fireflash app as described here in Step 3, you only need to flash these files with fireflash to get TWRP working AFTER you root with this post.

kfhd8-twrp-2.7.0.0-recovery.img
kfhd8-freedom-boot-8.4.6.img
kfhd8-u-boot-prod-8.1.4.bin

Kindle Fire HD 8.9
Android OS ver: 8.4.9

Hello all,

I updated TWRP to 2.8.7.0 and mention cm-12.1 in the instructions.

NOTE: All of the file download links have been moved to Dev-Host (since goo.im is down).

Sorry for the delay.

Enjoy

<QUOTE> *DONT RE-FLASH FREEDOM-BOOT.IMG LATER AFTER FLASHING CUSTOM ROMS -- IT'S FOR STOCK AMAZON OS ONLY / FIRST INSTALL ONLY* </QUOTE>

So... if I had stupidly forgotten that part and re-flashed the freedom-boot.img over the top of already flashed TWR and CM12, and now the device won't boot normally or into recovery... any suggestions? The only thing I can boot it into is fastboot.

I tried reflashing all my stock backups, it didn't work. I tried TW recovery again and that didn't work.

Any help would be much appreciated!

The easiest method to get back into TWRP would be:
- flash TWRP recovery image with fastboot
- flash a boot.img from the CM-12.1 ROM with fastboot ( you can open the zip and pull this file out manually )
- and then run this command on your host "fastboot -i 0x1949 oem recovery"

From there flash a ROM, etc.

So I installed a nightly few weeks ago. But it needed new google apps which I didn't know at the time. So I thought lets try a factory reset, whats the problem in that, right? Nope. Now all my Kindle does is shows Orange logo then blue logo then once it reaches TEAMWIN blue logo screen, it keeps flashing that screen. Computer can't detect it because it keeps rebooting every second, got a factory cable from ebay which does nothing because again the device keeps rebooting. I think I just lost my kindle.

And googling didn't help as I found only one person who did exactly what I did and he never got any answers. Just wanted to say thank you to hashcode for nice days of using CM11 on my kindle before I give up and trash it. Any help/direction appreciated. Thanks.

you don't need a factory cable for this device.
you can try to flash back to the stock system, fastboot should be working.

theSuda · Jul 22, 2015

Is there any way to put it in fastboot mode without connecting it to PC? Like my old LG P500 phone had a combo of buttons that put it in emergency mode and you could repair from there. Anything like that for 8.9? Because that's my problem, it reboots so quickly that computer can't even detect the tablet. I know the basics of reflashing/unbricking etc as I have bricked my mobile phones a lot by using all nightlies. This is the first time I am stuck without a way to put it in fastboot. :\

What if I only want to update the 2nd BL from 2.7 to 2.8??? Do I really need the entire process again as if I'm doing it for the first time?

"Android ADB Composite USB" driver

slacka-vt said:
...... in fast boot, the kindle will show up as "Jem -XXX-XXX" and you need to use the "Android ADB Composite USB" driver.....

With fastboot indicating a jem-xxx-xxx device you must have worked with KF HD 8.9". Could you report your serial number prefix? Examples here and here. Also would you please give your model, i.e. 3HT7G?

Also with regards to the Android ADB driver, did you may make changes to android_winusb.inf file found inside usb_driver , to add support for your Kindle HD 8.9. If so did you edit the usb_driver with the fastboot name jem-???-xxx ? That driver update procedure and information is here. Is this how you updated the device driver? Thanks @slacka-vt.

Also what was your Kindle OS.? Such as: Android OS 4.0.3 System Version 8.5.1. You did not have to downgrade to version 8.1.4?

Hooray! I did it!

It took me a few days to get it but it wasn't because of Hashcode's instructions, my problem was getting the damn drivers to recognize the Kindle on Adb mode.

I was on an old Xp laptop that was slow as hell, huge pain. Apparently there were two types of drivers (for WinXp anyway). One was just the simple driver to browse the kindles files like an external device which couldn't be recognized by adb.exe & fastboot.exe so after researching and digging I finally found theAmazon drivers for adb, deleted old drivers, installed adb Amazon drivers & eureka adb commands where finally recognized by device!

After that it went fairly quick. Only problem I had in the instructions was the powering up & down + all the plugging & unplugging the USB.

The kindle automatically powers on when you plug it in so I got hung up for alittle bit there on the fastboot portion of the installation. Very Confusing.

Trudged thru & finally figured out a method that worked.

Only issues I've had so far is the browsers are kinda buggy. Default CM12.1 browser is missing some features like press & hold on link to bring up some options is empty.
Chrome browser is constantly flashing tiles in random areas.

Other than that tho pretty cool! Will tinker around with it some more.
Isthere there someplace I should post about bugs & stuff for the developers?

I'm still pretty new here still.

Found out the issue with the press & hold on links in stock browser being empty. It was a custom theme issue.

Modding the 2nd bootloader splash

What if I wanted to modify the second bootloader's splash screen (the blue Kindle Fire logo)? I have the new initlogo.rle file modified and ready to pack into a u-boot image, but I don't know how to compile u-boot for the kindle. Also, once I have the u-boot image compiled, would I flash it directly to the bootloader partition in fastboot, or would I need to wrap the image into a boot partition file somehow?
