KUAL won't launch due to an error

[Classic_reader]

I'm on Kindle DXG ("B009A1010...") with FW 2.5.8.
I've recently successfully conducted the installation sequence (from https://www.mobileread.com/forums/sh...php?t=225030): "jailbreak --> MRPI --> MKK --> KUAL -->KOreader". But KUAL entry constantly throws the error:
"The permissions to open the requested title have an invalid date. Please contact customer service.".

What I've tried:
- I tried the solution with kindletool from here https://www.mobileread.com/forums/sh...d.php?t=334740, putting `setdate.bin` to the root and trying to update, but it crashes with U006.
- I tried installing kindle-usbnetwork, but due to install-guide precondition "DO NOT reboot your device with a custom .bin in the Kindle's USB drive's root, it won't work.
NOTE: Current (i.e., from the Snapshots thread) packages *need* to be installed via MRPI instead" - it won't install as KUAL entry/menu doesn't work.
The older version like usbnetwork25-0.11 also does not work/update (though update_usbnetwork-dx.bin).
- When Turn on wireless network it does not connect anywhere, so I can't refresh time through it.

How to break this vicious circle and make KUAL (with KOreader) work?

Perhaps the battery went flat and so it's 1970.
I've a "jail broken" DXG and can only set the date by connecting to 3G. Can take up to a day.
I couldn't get USB networking working, but sleep screen based on cover works.

Edit:
Both 3G and 2G still work here, but often the DXG uses EDGE (2G). There is no WiFi on the DXG. Do you have a local 2G or 3G service?

I think the worst ereader I ever bought. The KK3 is far far better. The DXG was a missed opportunity that they only updated the screen (from DX) and not RAM etc, like a KK3, which can do AZW3 and embedded fonts. Bought for PDFs and far too slow and low resolution for them.

I'm *fairly* sure the ;setdate search command existed at the time, so you don't really have to faff about with anything more complex.

There are some, but perhaps, they differ in frequency band. Actually, I couldn't ever had connected to any network (I wrote it off to its oldness).

Well, that makes us to not feel sorry about it in hack experiments.
I bought it just because of big screen for PDF, but I really expected it to be hacked for DJVU+FB2 formats.
Actually, I could be satisfied with Duokan tool, but it does not open FB2 (pdf, djvu and fb2 are the crucial triad for me).
Hoped, that KUAL + KOreader could become an advanced alternative.

I've just did the following: pressed DEL and entered

;setdate

.
Nothing changed, it just showed a page with Files found: 0 title.
Any other hints?

[NiLuJe]

It requires an argument (possibly an Epoch).

It might also be called ;settime, I always mix the two up. Don't have a Kindle on hand to check.

Maybe on earlier FW. Doesn't work on my DXG or KK3 (it needs WiFi for date).
Crazy no user setting.

I tried both (separately, and optionally with restart):

;setdate 1698856572

;settime 1698856572

Nothing has changed. KUAL still emits the same error.

[JSWolf]

IMHO, it's time to lay the DX to rest and buy a different Reader.

According to the Wiki, you're not supposed to use epochs with ;setTime:

;st - alias of ;setTime (format: yyyy-mm-dd HH:MM – e.g.: ;st 2012-07-22 17:59)

Maybe this different format will work.

Unfortunately, did not help.
Actually, I would not bother with it, but the silliness is that all the tools (for KOreader) were installed successfully, but are blocked by a primitive error.

[Ebookus]

did you ever find a solution to this? I am getting the same problem on a kindle 3, that was working fine just a few days ago. not sure how the date got suddenly messed up when the device was on and working fine.

[aha]

Same here with a K3 on 3.4.2. There are people having the same problem in a few reddit forums too.

My Kindle DX, which was fake registered, doesn't have this problem (or hasn't had it yet).

The K3 is not registered and had not been online at all. The date on it was correct. I tried reinstalling MKK but that didn't work. I tried fake registering in case that made a difference, but couldn't get the registration to work. (I tried using the same method as for the DX running 2.5.8, which I gather isn't right for 3.x fw but I don't know what the correct method is.)

Someone in a different thread mentioned the problem might be expired certificates. So I tried changing the date to an earlier one manually with the usbNetwork hack.

That worked! A temporary fix but a fix nonetheless.

Wreaks some havoc with reading stats on koreader, though...

could you please explain in detail what to do after installing the usbnetwork hack bin file? thank you

[aha]

Sure. I basically followed the instructions in here.

That post has an attachment that can apparently be used to do the date change much more easily. I did it manually because (a) I don't love running bin files without source and (b) the bin was for the DX and K2 and I had a K3.

So here's the manual way, once the usbnetwork hack is installed. It's described in that post and in the instructions included in the usbnetwork install files but here's my summary in case it's any clearer.

Notes:

* You probably don't need to do any of this! Looks like NiLuJe just posted updated KUAL files here and updated certification keys here. Also there's a ;setTime command that supposedly lets you just set the time from the search bar on some models. It didn't work for me, but maybe it'll work for you!

So I'm just posting this in case it ever helps anyone out for some reason. That... and I'd already started typing it out when I saw the KUAL update.

* These are Linux instructions since that's what I have. There are some notes for Windows users in the post linked above.

* I've done this on a DX and a K3. Details may differ with later models. See the other post and also the README_FIRST.txt file that's in the usbnetwork zip.

* The only complication I ran into was that the telnet/ssh connection to the kindle kept being killed all the time. I saw a fix for this but it didn't work for me and since this is such a quick thing I didn't bother looking for a better fix. Just type things fast once you connect!


Instructions:

1. Connect your device to the computer. Eject it so it's not showing up as a USB drive.
2. On the device, hit DEL to get the search bar
3. Type ;debugOn to enter debug mode (I don't think capitalization actually matters). Use the Sym key to get the semicolon. If it works nothing happens except the search bar is closed- you won't get any "no search results found" notice.
4. Type `usbNetwork (if you're on firmware 2.x - generally true for DX or K2) or ~usbNetwork (on firmware 3.x, like a K3) to toggle networking on or off. Again, if it works the search bar will just close.

5. On your computer, your network manager or whatever it's called will have noticed there's a new wired connection. Go into the settings for that connection and find the name your computer has assigned that connection. (On mine it changed depending on the usb port I used but the names were things like usb0, enp0s[some number], enxee4900000000, etc. These are Linux names, on other systems it'll be different.)

6. (This one is Linux-specific. I don't know what the equivalent to ifconfig is on Windows or Mac. Check the other documentation.) In a terminal, run the command sudo ifconfig [whatever the network name is] 192.168.2.1

7. Type either telnet 192.168.2.2 or ssh root@192.168.2.2. If you use ssh, any password will work including a blank one. After this, you'll be logged into the kindle itself and the commands you run will run on it.

Note: the change from 192.168.2.1 in step 6 to ...2.2 in step 7 isn't a typo. The first is the address the kindle assumes for the computer (host) and the second is the address assigned to the device.

Once you're logged in:

8. Type date -u [MMDDhhmmYYYY] to set the new time and date. For example, date -u 041908152024 will set the date to 8:15am on April 19 2024.

9. Type hwclock -w

10. You can type hwclock to check the results

11. Disconnect from your telnet/ssh session if it hasn't already kicked you out. (Depending on your connection, type quit or exit or ctrl-D or just close the terminal.)

12. On Linux, type ifconfig [network name] down

13. On the kindle, ~usbNetwork again to toggle it off and ;debugOff to exit debug mode
