PW2 Please help me update my jailbroken PW2

[ecircuit]

Hello friends,
years ago I did a jailbreak on my PW2 with the help of this forum.

I thought it would be a good idea to update my device and jailbreak it again.

I did a lot of research here but I am very unsure how to proceed.

SN Prefix: 90D4 -> Kindle PW2
Current firmware: 5.4.2

Here is my plan. Please tell me if I am good to go:

1) Reset the device over menu
2) Download firmware factory_PW2_5.4.3.2_initial, check MD5 (3cbac0b4821cec03432b9ed382744f41), update the device via menu
3) Download and install kindle-jailbreak-1.16.N-r16552.tar.xz -> K5 JailBreak
5) The device is jailbroken again
4) Download official Amazon firmware customer_PW2_5.8.7.0.1_update to get on firmware 5.8.7.0.1
5) What to do with this update file? Install it via the menu like 2) or install KUAL + MrPI first and update the device via MrPI? No hotfix for PW2 needed so that the jailbreak can survice?
6) Check to turn off WiFi + creater folder update.bin.tmp.partial to keep OTA away
7) Install KUAL if not needed in 5) + install Koreader
8) Install dictionaries, but where to get them and where to put the files in?

As you can see I am a liitle bit overwhelmed, I don't know how I managed to do it before :-)

Any help much appreciated, thank you!

When things go right, you only ever have to jailbreak once, but you do have to take steps to preserve the jailbreak. You do not need to reset. If you have applied the latest hotfix, just update to the firmware you want (but stay away from 5.12.x), then reinstall the various goodies.
