From Amazon website (the firmware updates).

Note, I've actually tested MRPI (from the snapshots) on factory 5.10.0.2 and it worked. In this case, your problem is you're using a version of MRPI that's too old so even installing customer firmware isn't going to solve the problem.

Amazon's Kindle Software Update page. Just tweak the version number in the URL .

EDIT: Whee, missed a new page again! .

[thechordmaster]

Thanks!
Could you please clarify what exactly you mean by tweaking the version number?
i visited this page: https://www.amazon.in/gp/help/custom...4HPVAW86CHYHKS

I have this link: https://s3.amazonaws.com/firmwaredow..._v2_5.10.2.bin

Should i download this or should i rename it to something else?

Thanks

If you want to install 5.10.2, then yes, download that one.

Otherwise, if you want to install 5.10.1.2 (your only other choice at the moment) then change the "_5.10.2.bin" sub-string of the URL to "_5.10.1.2.bin"

Ok.. So I've updated my kindle to 5.10.1.2...
Im still not able to see kual on my kindle.
Can someone link me to the exact steps to be followed to install kual?
I've extracted the extensions and mrpackages folder to root and copied the coplate update to the second folder.
Ran ;log mrpi
Device restarts but nothing shows up
I assume the.azw2 file to the documents folder because I read that it is redundant

[thechordmaster]

Btw.. This is my log MRPI:

Running 'install.sh' for 'KUALBooklet 78183a5 I' (Update_KUALBooklet_78183a5_install.bin) @ Sun, 06 Jan 2019 15:36:18 +0530

[FBInk] FBIO_EINK_UPDATE_DISPLAY_AREA: Invalid argument!
[FBInk] Failed to refresh the screen!
Failed to display a progressbar!

Hu oh... Got return code 255 . . .

@thechordmaster: You're still using old packages. You need to get your stuff from the snapshots.

EDIT: Hmm, or possibly you've got leftovers from the old packages.

Delete *all* of these first (at least those you can find from this list):

linkss/bin/fbink
linkfonts/bin/fbink
libkh/bin/fbink
usbnet/bin/fbink

[thechordmaster]

Are these files on root level? I am not able to view these files if i connect my Kindle to mac

[thechordmaster]

Whew folks!
Finally managed to get KUAL and install the screensavers hack.
One last question.
I installed Koreader from github...
Now everytime i open filemanager from its options, my kindle returns to the screen. I have already copied a few epubs to my documents folder.
Anything i missed out on?

I used this FYI

My log reads:
It's a scroll... It's a codex... It's KOReader!

Congrats, looks like you (again) have the wrong version file.
(I don't use KOReader, so I do not know for certain, just making a guess here.)

[thechordmaster]

Haha..
the guides say use the nightly builds...That was the most recent version i could find.

That should be the correct version. I use the same PW2 builds on my PW3s and PW4s (as recommended by KOReader devs).

I wonder if it's because OP has an Indian variant of the PW4 (G001 0209).

[thechordmaster]

Thanks! could be. What is the right thread to post a request for my variant?

[NiLuJe]

Ah, no, that's my bad.

I knew I'd forgotten to add the two Indian PW4 somewhere, and you just found out where ;D.

It'll be fixed in a few days .
