~ds disable sleep capability supposedly removed

[j.p.s]

The ability to disable sleep by doing a search on ~ds has supposedly been removed in recent firmware (but might be related to "special offers").

https://www.reddit.com/r/kindle/comm...nt_work_after/

Can anyone confirm?

And if so, do the KUAL extensions for sleep disable/enable still work?

I can't get it to work on my Oasis 2 running 5.14.3.0.1 or on PW5 SE running 5.14.2. Neither are jailbroken.

Thank you. Do either of them have "special offers"?

I checked /usr/share/webkit-1.0/pillow/debug_cmds.json in firmwares 5.14.1.1, 5.14.2, and 5.14.3.0.1

The line:

"~ds" : "/usr/bin/ds.sh",

is still present in 5.14.1.1 but gone in 5.14.2 and 5.14.3.0.1 but all three have the script
/usr/biusn/ds.sh so the ability to disable sleep can be restored by restoring the above line to debug_cmds.json and the KUAL extensions in the thread
https://www.mobileread.com/forums/sh...d.php?t=293264
to disable and reenable sleep should still work for firmwares greater than 5.14.1.1

Neither of them do.

After a lot of digging thorough code (and a ton of failures trying to jailbreak my KT3 with 5.15.1.1 firmware), I've found a very simple way to disable the mimic ~ds behavior - including on an unrooted/unjailbroken stock device.

Steps:
1) Connect to your Kindle via USB
2) Create a file in the root directory called "TESTD_PREVENT_SCREENSAVER" - can be an empty file, but must be named exactly. (It'll ultimately sit in /mnt/us/ )
3) Reboot the device

Note I am not entirely sure what other consequences this may have, so use at your own risk - from what I can tell, this should be relatively safe.

Wow, thank you so much for finding and sharing this! This is working on mine as well with the most current firmware with no jailbreak.

Honestly, I just need my web app stay on screen without it going to the screensaver, so I don't need a full jailbreak anyway, so this is perfect.

Nice, want to try on Scribe. When using for sheet music, fake books etc one needs to keep it from sleeping somehow. Would be better if it were a Setting of course.

Or would it be better if there was a setting:
[ ] Sleep screen is current page

Or
Sleep screen setting accessible from current page:
( ) Adverts
( ) Kindle images
( ) Book cover
( ) Current page
( ) Random from images folder
( ) Specific image or page
( ) Nothing, see dirt when cleaning.

Happy to help - and glad it worked for you as well. That's exactly my use case as well... trying to keep a webapp on screen all the time.

I'm yet to figure out a way to make the browser "fullscreen" or somehow hide the address bar... still poking around more in case there are some hidden settings. This https://www.mobileread.com/forums/sh...84&postcount=8 seems like a promising direction, but I haven't found anything yet.

That's a great finding, however, after testing it for a while I concluded that even the magnetic case doesn't put the device into sleep mode (apparently it only turns off the backlight), which results in a relatively quick battery draining.
For me the ideal solution would be to extend the timeout from 10 minutes to some larger value (or a very large value to simulate infinity). Do you perhaps have any idea how to change this value? I have a jaibroken PW5.

See this thread for pointers to where this has been discussed before. I haven't tried it myself, but there is a parameter which sets the timeout and it can be changed.

I did try to use kdb as suggested here https://www.mobileread.com/forums/sh...0&postcount=12

# kdb get system/daemon/powerd/t1_timeout
600

# kdb set system/daemon/powerd/t1_timeout 1200
kdb set: 'system/daemon/powerd/t1_timeout'

# kdb get system/daemon/powerd/t1_timeout
600

The set command doesn't update the entry.
