i think i would need a new one from skorpion now

a new what? cable? your cable should be fine, fix your drivers so your computer can see your device. and reflash all your backups n swap your bootmode back to 1.

i'm trying to get my kfhd back from my dad so i can make a script to do all of this from within the OS. fastboot always gets noobs lost. i should have never sold my 2nd kfhd lol

This might be noobish question but why cant you use esfile explorer and go directly to the dev/block/platform/omap/omap_hsmmc.1/byname/ folder itself and just copy and paste these files to your download folder then transfer them to pc for use with backup

i think you should look into firekit and getting a working fastboot driver up and running. that way you can flash back the stock recovery and reset bootmode to 1.

I need help! Everything went fine, but when it booted, it showed an orange logo, then blue and orange again, but it just reboot and enter in recovery (without pressing anything)... Why does that happens? Any ideas :/...

I DONT have access to ADB just in case is useful

I Think I need a ZIP file.. for some reason, seems the System was wiped... (though I have all my files..) I have access to adb, but I cant use SU... Really, I need help :/... All that happens is that it goes Orange, then blue and then orange. After that, reboots and goes into recovery withouth pressing anything

SORRY I DO HAVE ADB AND FASTBOOT ACCESS... I will try to restore system and the other imgs. I couldn't back em up though... Dont know why, tried with 2 kindles and no luck so far.

if you have fastboot access can you try resetting bootmode to 1 like this:
fastboot -i 0x1949 oem bootmode 1

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

i realize there may be an issue with my instructions. And the fix is a rooted flashable .zip of the stock OS for use in TWRP, should this happen to anyone.

Ill create that here in a bit.

Yes I can. Or well, could. I was able to get this back working just by restoring the boot.img and recovery.img. So it seems like it was some of these that were doing something weird. Will try all this again though. If you upload the ZIP file, would be glad to test, though I dont really know what could've happened...

Leave the device powered off for now. I'm working on the .zip now.

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

Im back in stock (Flashed recovery and boot imgs), but as soon as you're done with the zip Im going back to TWRP. I need this for tomorrow (got some work with it) thats why I couldnt wait, but when you get this up again I'll gladly test it.

A note: My device WAS charging, not like Persanos. When I got it back up, I had 66% charge (I installed the recovery with around 40%). I used the amazon fast charge whatever, the point is that is was charging.

Is past midnight in my country and I got exams tomorrow, so I'll take my leave. Thanks for all you work Hashcode, Hope you get some sleep too!.

EDIT: I saw you changed the back up commands. I can tell it works now since I just tried it (Did it from the kindle, using a terminal... Went really smooth). I have my files backed, thabks, I'll try again tonight

I added a STEP 6 which is optional but recommended:

Because we had to drop a 4K file right in the middle of the operating system, there is a chance that we've killed a binary that is used by the OS. As a final "cleanup" step to installing the bootloader, I recommend everyone re-flash the OS to /system. The stack space is pre-allocated during this process so that the files going back onto the /system partition will NOT land on it anymore.

Download a flashable Amazon OS ROM (7.2.3): Amazon OS 7.2.3: http://goo.im/devs/Hashcode/tate/kfhd7-amazon-os-7.2.3.zip Place this in the /sdcard

This is the stock Amazon OS which is rooted, has Superuser.apk and busybox. (Users can use this as an easy means of going back to stock the easy way via recovery. It also includes the modified boot.img including the 2nd-bootloader).

INSTALL THE .ZIP IN TWRP:

Select "Install"
Use the file manager to browse and click on the "kfhd7-amazon-os-7.2.3.zip" file.
Swipe to start.
Once that's done, reboot.

NOTE: Once we start using Jellybean ROMS, the location of "sdcard" can move and to find this file you may need to go "Up a level" to find "data" and then "media" and look for it in there.

IDEAL cheers hashcode this is what i needed to fix my bootloop problem where the kindle would try to boot but then reboot and reboot and reboot,

i got so fed up and ran out of ideas i left the kindle with the recovery installed, but powered it off

i downloaded the zip and sideloaded it in the recovery then it installed no problems

rebooted bang back with working amazon os :laugh:

Hashcode, something I want to point out is that this command: :"fastboot -i 0x1949 oem idme bootmode 7" wont excecute. I tried several times and no results. My tablet booted on TWRP by itself since, as last time, it went Orange, then Blue, Orange again and reboot. After that, TWRP kicked in. I installed the ZIP file you provided and, Luckily for me: AMAZON STOCK OS WORKING!.

I do not know by any means why the command is not working, but I just wanted to confirm you there's something weird about it. If everyone else happens to come across that, then just avoid the step and continue. Enter in recovery yourself (or the bootloop will do it for you xD)

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

Well i was trying this on my brothers new laptop and my hd7 boots into fastboot no problem but the adb command hung at waiting for device. After a little googling i found out fastboot and usb 3.0 hate eachother

luckily my computer has 2.0 ports

will try it again when i get home and post the results.

Thanks for the heads up!
I removed that command so that I can test it here for a bit. And the instructions explain how to enter recovery right after that.

No sense in confusing people.
