I deleted some files in root accidentally; now it won't boot.

---

I deleted some critical files in /system directory accidentally, and it force closed / shut off.

When I tried turning it back on, it never gets past the "kindle fire" screen.

Connecting it to the computer and using adb, su command doesn't work, mount doesn't work... but it can detect the device.

So... am I screwed?

Unless someone discovers, or Kindle support can give you, a way to load the software via the boot loader, you're probably bricked.

I'm not sure if the boot loader has this functionality. Has anyone successfully extracted it yet?

I was playing around last night replacing packages and I did something similar...where I got stuck in the same situation. What I was able to do (and was very happy/surprised it worked) was using the root process to get back in.

The one I used was the one with the script you run which does everything for you. I'm on a mac so I hacked the runmemac.sh script and add in a few lines after the /system mount point was remounted rw to push out the apk's I had swapped and make sure the permissions were set right. I kicked off the script and it proceeded to root my kindle (even though it was not necessary) and put my packages back.

It's an ugly way...I could have just ran the individual commands but I was being lazy. It also means you need the original packages you removed first in order to put them back. But it worked.


Basically find this section in the script:


echo "--- remounting /system"
./$varadb shell "/data/local/tmp/busybox mount -o remount,rw /system"

and add:

./$varadb push whatever.apk /system/app/
./$varadb shell "chown root.root /system/app/whatever.apk"
./$varadb shell "chmod 644 /system/app/whatever.apk"

If push doesn't work, you can try install. I had a few trial and errors in the process but that is from my last go around which worked...twice.

It wouldn't mount... :/. *sigh*

The fire does have a recovery partition but I've not figured out how to trigger it during boot..

have you tried getting to it through ADB?

Nope..to easy I guess I tried ADB REBOOT RECOVERY with no success. It rebooted back to the lock screen

Download the standalone 6.1 update and adb in and put it in the updates folder. Then reboot.

How do I adb push files to /sdcard/kindleupdates/ directory?

After typing "adb devices" to show the device, I typed:
C:\adb> adb push update-kindle-6.1_D01E_2017120.bin /sdcard/kindlefireupdates/

To which I got:
failed to copy 'update-kindle....bin' to '/sdcard/kindlefireupdates/': Permission denied

I tried using "\":
C:\adb> adb push update-kindle-6.1_D01E_2017120.bin \sdcard\kindlefireupdates\

To which I got:
failed to copy 'update....bin' to '\sdcard\kindlefireupdates\': Read-only file system

Try this:
adb shell mount -w -t vfat /dev/block/mmcblk0p12 /mnt/sdcard
adb push update-kindle....bin /mnt/sdcard/kindleupdates

mount: Operation not permitted.


Doing:
adb shell su
results in "[1] Segmentation fault su"
