Uninstall it the regular way and then delete the KUAL.kual file living under the /documents directory.

The command in the script will be the same as on the command line -
if file exists rm the file.
I haven't looked, but there should be example if statements in there you can use as a guide.

No, this is not right. After uninstall in the regular way, the KUAL.kual file is already dead, but the "thing" is still there, not possible to be removed. Even after a reboot, this is still there.

I have extracted Update_KUALBooklet_v2.7_uninstall.bin using kindletool. KUAL Booklet uninstaller, the uninstall.sh script, has the proper command on line 26:

`rm -f "/mnt/us/documents/KUAL.kual"`

I can't see why it doesn't. Besides, line 16 reads as follows:

`rm -f "/opt/amazon/ebook/booklet/KUALBooklet.jar"`

Having checked out the mentioned directory, I have confirmed that the KUALBooklet.jar file too is still there after the uninstall.

Exactly. Just delete the KUAL.kual file manually. That is what I did to get rid of the KUAL (DOC) entry in the library.

I mean, the KUAL.kual file is already deleted, but the entry is active. Strange.

In my experience, the uninstall script doesn't remove it. It was still in there as a 0 B file.

Other than /mnt/us/documents/KUAL.kual, /opt/amazon/ebook/booklet/KUALBooklet.jar should be removed as well by the script. The second is a read-only directory so unlike KUAL.kual, KUALBooklet.jar cannot be deleted manually w/o changing permissions.

/mnt/us/documents/ should be read/write and it is FAT-32 so it does not support fancy acls like immutable.

/opt/amazon/ebook/booklet is most likely read-only.
The script would have to change the file system option to rw if that is so.
Which means the script must be running as user: 'root'
Does the script switch user to the user: 'root' ?

AND
Do you have MKK installed?
It was (should have been) installed in Step #6 of the jailbreak instructions.
If not, or if unsure, install it again - it will do no harm if it was previously installed.

That package also installs the utility used by our add-in packages to gain 'root' permissions.

Step 6 is rejected when disconnecting USB by last firmware 5.8.5.0.2 for KV.

On 5.8.5.0.2 there are more things going wrong:

- USB networking does not work anymore
- Kual uninstall does not remove the entry, but removes the file

"Does not" should be read as "I cannot make it to".

You MUST use MrPI to install update_*.bin name format packages with customer firmware.
At the point of Step #6 instructions, you are still running FACTORY firmware.

You are missing the utilities installed during Step #6.
Use MrPI to install the hotfix package.

Hey!
Behavior of Factory Firmware != Behavior of Customer Firmware.
That is the entire basis of the current jail break procedure, just for those who missed the point (it is not the downgrade in firmware version number, it is the change from Customer -> Factory firmware that enables the process).

Two steps to get rid of the entry in the Kindle Library on KV, FW 5.8.5.0.2.

1. Reinstall the booklet version and manually delete the application file, i.e. /mnt/us/documents/KUAL.kual.

2. Then run Update_KUALBooklet_v2.7_uninstall.bin to uninstall and deregister the booklet, i.e. /opt/amazon/ebook/booklet/KUALBooklet.jar and cleanup. For the second step, you will need the kindlet version, i.e. KUAL-KDK-2.0.azw2.

Correct.

Yes, it is read-only.

Yes, I have it installed. JB survived as expected. Just renewed my usbnet installation for SSH, which is what I basically use the JB for.

I reinstalled the booklet and uninstalled it. See the outputs below from /mnt/us/extensions/MRInstaller/log/mrinstaller.log:

I have confirmed that the uninstall script removes the application file and the booklet but leaves the KUAL entry in the Kindle library.

For the only way to get rid of the KUAL entry, see #1691.

I am attaching the related scripts contained in Update_KUALBooklet_v2.7_install.bin and Update_KUALBooklet_v2.7_uninstall.bin for those who might wish to look into the problem.

Thanks.
That will give someone a start.

(There is no way in the world I can do support, I am lucky to have time to answer questions.)

The problem is not FW 5.8.5.0.2 specific. Just gave it a try on PW, FW 5.6.1.1. Uninstall script removes the booklet and the application file but not the KUAL entry in the library. Now I have a very beautiful Application Error box on my PW when I try to call KUAL booklet.

Right. Nice trick. Worked brilliantly. Thanks a lot indeed.
