Help : Remove GUI-Launcher before update ?

[walter_2]

Hi,

*edit: Is is a Kindle Tocuh WiFi - so it is Kindle5*

middle of 2012 I have jailbreaked a kindle touch (5.1.0) with website ( jailbreak-kt.tk ) or something like this. After installation it was possible to install usbnet and GUI-Launcher and launcher-addons (sokoban,term,new reader) also from this webside 'per klick' - without any PC.
Now I want to remove these addons and the GUI-Launcher to be prepared for an kindle update. But I do not have files for uninstalling.
There is no menu item to detect installed versions of this additional stuff.
So I have these questions:
(1) Howto uninstall GUI-Launcher addons ? (but no zip-files avail)
(2) Howto uninstall GUI-Launcher itself ? (but no zip-file avail)
---
(3) Howto detect which version of GUI-Launcher is installed ?
(4) Howto detect which version has the usbnet jb ?
(5) Is it possible to 'update' the usbnet jb with a newer version ?
---
(6) Is it possible to use 'nearby' version-zip files for uninstalling ?

Thank you
- I hope it was not describe'd to cryptic -
br

You can normally use the uninstallers for the most recent version of tools. You should find installer / uninstaller links here: https://wiki.mobileread.com/wiki/Kindle_Touch_Hacking

Otherwise, it may be easier, faster, and safer to just flash a pristine 5.1.2 image using the "simple debrick" method, rather than trying to uninstall all modifications.

What is to do if in diag mode ssh wont work ? Because ktouch is not bricked can I jailbreak it again to have a newer version of diag-software ?
Or I have to flush diag kernel 5.0.0 before flashing 5.1.2?
