5.16.21 KPW Signature (JB+Hotfix) - KOReader + KUAL auto-removed from /documents

dkinor · 10-02-2024, 12:33 AM

Just a warning:

I have a jailbroken Kindle Paperwhite Signature (11th gen) 32GB that I updated to 5.16.21. Following directions here (https://fw.notmarek.com/khf/ - at my own risk, I know!) to update to 5.16.21, and then installing HF hotfix, HF MRPI, KUAL, KOReader, and KOL asap booklet, and installing/applying coversetter and BinaryRenamer, I decided to connect to WiFi and register with Amazon. Discovered that Amazon has ability (whether through registration, or through latest firmware) to go into my /documents folder, and remove the KUAL.kual and KOReader.kol files (making KUAL and KOReader inaccessible from my Kindle PW's GUI). My fix was to reinstall everything (starting with hotfix).

I was able to replicate this issue (and fix) with my Kindle Oasis 3 (10th).

I tried downgrading to do a clean install of 5.16.2 using instructions on this site and the RUNME.sh script, and got an error during the update process (UPDATE ERROR: 11).

Not cool, Amazon (who owns this device, and the documents in the /documents folder, btw?)!

Questions to the communithy:
1. Is there some additional binary in the .21 FW version that can go into the /documents directory and remove specific files? Or, some other mechanism for Amazon to remove my files in /documents directory?
2. Any thoughts as to workaround to make downgrade possible?

Thanks in advance for any info!

Documents gets wiped during de/registration i think there's a flag file you can make to skip it.

From /usr/sbin/deleteUserContent ,
create an empty file without extension in /var/local/system/ called DONT_DELETE_CONTENT_ON_DEREGISTRATION

Haven’t tested it though (FW 5.16.21, Kindle Scribe)
