Turning off charging for long term USB power

$
0
0
I'm preparing to jb my KOA2 and began by looking over the mountable drive contents. I hadn't looked inside in a long time (Turns out I hadn't made the update preventor directory yet, so it's good I checked.

Anyway, there turned out to be a file
.fuse_hidden0000020c00000001
which I thought might have been put there by my laptop, but it has a 2017-10-13 time stamp, weeks before KOA2 release. Turns out it is a shell script.
Code:

#!/bin/bash

while true; do

CAPACITY=$(cat /sys/class/power_supply/max77796-battery/capacity)

if [ $CAPACITY -gt 70 ]; then
echo 0 > /sys/class/power_supply/max77796-charger/charging
elif [ $CAPACITY -lt 65 ]; then
echo 1 > /sys/class/power_supply/max77796-charger/charging
fi

sleep 30
done

The Voyage doesn't have a /sys/class/power_supply/max77796-charger directory and on the Voyage /sys/class/power_supply/max77696-charger directory doesn't have a charging entry.

Maybe I'm the only one that cares, but this looks like a good way to have a Kindle max out at 50% or so when on a charger long term.

KT2 Jailbreak on 5.9.2.0.1

Quote:

There is a single, complex, special case for 5.8.9.0.1 firmware version. If you get a Kindle with that firmware version, please just post in this thread before you do anything to it, your device **might** be one of the rare exceptions.
5_x_Jailbreak

I understand this also applies to 5.9.2.0.1? If so, what information is needed, and what are the steps?

I only have access to the device a few days every few weeks, jailbreaking for someone else.

Also, did I use the right prefix for a 2017 Kindle Touch?

Any chance for my PW2 5.8.11?

Dumb me, I was about to proceed with the whole thing, and then it updated to 5.8.11. As someone earlier mentioned, I find confusing information about if it is possible or not to downgrade or jailbreak it.

Could someone that know more about this subject if this model with this version can be worked on?

KINDLE PW3 5.8.11 Jailbreak/Downgrade

Hey guys, just bought a kindle and it has this firmware: 5.8.11.

It's a PW3. Is there any method to jailbreak it/ downgrade it?

How much would people pay for easy serial jailbreaking their paperwhite?

$

I was thinking that someone with a 3d printer, or good woodworking skills, or a variety of other techniques could manufacter a back cover for that paperwhite and basic kindles, that make it easy to serial jailbreak.

The idea is that the back cover of a paperwhite has the screws in a known location, and the serial debugging pins would be at a known offset of that.

Then someone wouldn't have to solder to thier motherboard, but they could buy a replacement back cover, that had holes directly over the serial pad that let them plug something like this into it: https://en.wikipedia.org/wiki/Pogo_pin

They would still need to take the front cover off, unscrew all the screws, and put on this replacement back cover.


Alternatively, a frame of some sort you could slip your kindle in, and then use an exacto knife to cut out a square of the back, and then a replacemnt square could be clicked in place that had those pins on it.

Just a wild thought that ran through my mind the other day

Confused on PW models & jailbreaking

$

I am considering getting a PW - I have a 3 year old Fire that I really use only for reading and think a PW might be better for my needs. I use Calibre to manage our ebooks and Calibre Companion on the Fire. That works really well.

We homeschool and I use tags to organize via grade level and subject so it's easy to find what I need at the moment. Plus my own personal books are organized with tags.

It looks to me like a jailbreak and Calibre Collections is the best way to manage books in a similar fashion.

From what I'm seeing, the newest PaperWhite cannot be jailbroken? Should I look at a refurbished older model? Is there a certain firmware I need to look at?

Or is there another option using the newest other than manually adding to collections (I have found some tips for doing that quickly if need be, but it doesn't sound ideal).

Any help is greatly appreciated - or if there's a guide that really breaks down which generations are available, which can be jailbroken, etc. I can look at that. I'm just honestly not sure which generation the current PW on Amazon is, the firmware, etc...

Thank you!

PW3 flash jailbroken system over new PW3?

$

I have a jailbroken PW3
I am getting a new PW3 for a friend, I would like to give it in a jailbroken state

Would it be possible to flash - either by kindletool or dd, the jailbroken system (and boot and initramfs?) partitions and end up with a new jailbroken kindle? Via USB and not serial, as I don't want to crack the case.

I don't have the device on me, so I'm relying on the userstore info from knc1's wonderful research https://www.mobileread.com/forums/sh...ght=filesystem and https://www.mobileread.com/forums/sh...d.php?t=262234

If this is a viable strategy - where does lab126 store the s/n and other uniquely identifying information - I won't want to overwrite this, or will need to back it up and then rewrite it after the main flash.

I have searched the forums and haven't seen someone cover this, and alas, everyone was away from irc when I check in the channel. If my query duplicates something written here or on the wiki, please direct me to it, as my googlefu has failed!

Thanks!

Why is registration needed before jailbreaking?

Hi

I've read several times that the device has to be registered before to attempt a jailbreak. Is there a technical reason? Could it cause a problem to try to downgrade & then jailbreak a device that has never been registered with amazon?

Thanks!

PW3 Restore to factory default from diag menu (without using serial)

$

Hi

I've access to a kindle that was stuck on the tree. Following knc1's advice on another thread I let it on the power for a couple of days, it ended up in diag mode. I have a hard time finding information about the diag mode and what can be done with it (maybe I missed a dedicated topic).

I suspect a corruption of the userspace filesystem. As I understand it the kindle now did a fresh format of this one.

What is the best way reset to factory defaults (or to a new/clean image I'd download from amazon servers) from the diag mode, without having to connect the serial?

edit: uploaded a new image on the filesystem, got out of diag mode it installed the upgrade, could now do a factory reset from the params. Problem solved. Would be curious to know what the best way is for cases where the kindle would have a broken system, unable to reboot on it.

:thanks: for the charger + wait tip, worked great!

So Amazon doesn't allow for 3g web browsing anymore, but can the jailbreak get around this somehow? Is there a way to get any data over 3g ?

Kindle Previewer 3 (3.20.1) & annoying indexing

$
0
0
Hi all,

I updated Kindle Previewer to its 3.20.1 version yesterday. I like it very much except for the annoying (for me, at least) indexing thing: every time a mobi file is open with KP 3 (normally, the result of an ePub file converted with kindlegen), KP 3 indexes its content, so I have to wait till the indexing is finished. As I use KP 3 just to verify if the conversion made with kindlegen is OK, my question is if there is a way to avoid indexing in KP 3.
TIA

[Excuse me if this is not the right place to ask this and, of course, for my bad command in English: Spanish is my mother tongue.]

My kpw3 firmware is 5.9.2.0.1.If there is anyway I can jailbreak my kpw3?

I am going to be doing some research on it, to see what is different from the 4GB.

But I am probability not going to open the case up. If It is not capable of being jailbroken with our current methods, I am just going to leave it stock.


Anything you want me to look into when I get it open, post it here.

Kindle Manual Update FW Binaries

$

Hi all, I am sorry if this has been posted before, but I am having a devil of a time trying to search for it on these forums:

I have a PW, and I am able to JB it by downgrading to 5.3.3, and I can keep the JB through updating to 5.6.1.1 manually with the FW bin provided on Amazon's site. However, this currently breaks the ability to use nested collections, as well as a few other hacks that I would like to keep.

Is there a repository of previous updates that can be applied manually, so that I can use the latest FW version which still supports the hacks I use (say, just prior to 5.4.2)?

Thanks for the help.

Help Request: Advice with jailbreaking/hacking new Kindles

$

So first I would like to apologize for being as thick-headed as I am. I promise that I have at least tried to read and understand the various mobileread threads and wiki pages related to the topic of "hacking" a kindle, but I still seem to not be able to grasp the bigger picture.

My problem:
I want to purchase one of the new "nicer" Kindle eReaders (either the latest Oasis or the Voyage) and then jailbreak it to enable extra functionality.

In particualar I would like to:
  • install koreader to read .epub ebooks
  • install kterm to hack arround with my device
  • be able to install most of the different apps made by the community

So I found that there ar in fact jailbreaks available for these devices, however it looks like they are connected to very specific firmware versions which my device may or may not ship with (?). Moreover some of the more "important"(?) kindle apps (like KUAL) seem to not be currently supported on these devices.

My Questions:
  • If I order a KV or KOA2 how likely is it that I'll get a version which I can jailbreak?
  • If I then manage to jailbreak my device, what stuff will I be able to run on it? Will KUAL work? Will koreader work? Will kterm work?

I hope I have been specific enough about what I would like to know! Anyways, I would appreciate any and all advice you kind people might throw my way! :thanks:
