Hi all,
for all who have issue that "The title is not signed by a registered developer"
I found a temporary solution until developers pitch in to correct the issue.
This is the only solution that worked for me on KPW1 after 3 days and multiple resets. Upgrade to 5.6.1.1 finally after everything worked for me.
I will say what I done, so modify it according to your needs
- Freshly reset the device
- Right now I am in 5.3.3
- Updated it to 5.4.4 (" why, I don't know. I thought it is safe for 5.4.x so why don't update to border ")
- Now jailbreak it as the official
snapshot page says.
- Simply put, download "
kindle-jailbreak-1.16.N-r19426.tar.xz" > extract kindle-5.4-jailbreak.zip > extract and put all files into root folder of kindle.
- Come to settings > update
you will see ***JAIL BREAK***
- Now what I done is, copy the latest .bin for K5 from
DevCerts-20250419-KeyStore.zip, placed in root folder
- again, settings > update
- now, install MRPI from this
link as instructed. Once you are in 5.6.x.x you cant update any .bin by normal method only MRPI is the way for now.
- now copy latest
Kual from official page and extract KUAL-KDK-2.0.azw2 and place in documents folder
- Still you can see when you open KUAL it says error.
- Now magic part, update kindle KPW1 to latest
firmware, you know how -> place in root folder then settings > update
Check this screenshot of kindle root folder before updating
- while booting make sure you seen ***BRIDGE+***
- Volla now open KUAL , it worked for me.
- next install extensions like KOREADER or update .bin things using MRPI.
I am happy to write this post, as this should help someone who is struggling to use their old kindles.
This is chaitanya ...
