Kindle Paperwhite 1 with fw 5.3.3 and Aeroplane Mode constantly on.

I'm hesitant to update the fw as @chaitanyal suggests because the newer it gets the more issues there appears to be.

Tried updating just the keys, didn't work. Tried a factory reset and full fresh jailbreak and KUAL install, didn't work.

Tried to change the date just to get past the cert expiration but I can only figure out how to change the time, not the date.

Luckily this has only happened to my Kindle because I was trying to put new textbooks on for uni so I've warned my partner never to exit KOReader on theirs. I would greatly appreciate some help as I struggle to read for long periods of time on my computer screen and would really rather read textbooks on the Kindle instead.

Thank you!
Absolutely nothing worked for me on my PW1 with 5.3.3., I HAD to follow @chaitanyal's method. I have not encountered any issues on 5.6.1 and my devide including KOReader actually runs MUCH smoother now. I also keep my device on airplane mode because I have no need for online features.
