On this device we can't access cfg files anymore.
I would like to install KoReader but I think it will be rather impossible for me.
Is there an explorer which shows such files ? Does anyone has an idea on all this ?
Thank you for your replies !

You have to enable the View of hidden and/or Protected Operating System Files:

View Protected Operating System Files

For Windows the name of the folder "system" is something to protect.

I just tried to jailbreak my Pocketbook 614W (Pocketbook Basic 3), software version U614-2.5.17.964, with pbjb-v8-16-g8f1fb88, but it doesn't work. When I run @Jailbreak from the application, the screen briefly refreshes, but nothing happens. When I try to run @Services it says "Unable to start the program".

Is there a way to jailbreak the Pocketbook Basic 3?

[due_rr]

The jailbreak failed on a PB Lux 3 running 626.5.14.791, but after updated to 626.5.20.1157 it worked!

Switching light on and setting brightness, or opening book you will have to create event sequence for touch moves (for example turning light on will be: open options->turn ligh on -> close options). I can help you with that. Opening books remotely is possible, but it will be difficult to accomplish, as far as I know, it is not possible to open book via ssh (with command like 'open Romeo and Julia'), but I will check it.

As I said before if you need any help, let me know.
Cheers!

Hi,
I tried your Android App with my first gen. Inkpad 3 and the latest firmware but i didnt get it to work. Maybe you can help me?

Root and Services works. Ssh connection too.
Login via ssh shows /mnt/secure/ #
Now i type cat /dev/input/event0 > f.txt and press the forward button at the Inkpad. Terminal shows no input but create a f.txt in /secure after ctrl+c
Same with b.txt
Android App does not work.

I tried cat event0 to event8 and pressing buttons on Inkpad and event4 works with buttons and event5 with touch.
Now typed cat /dev/input/event4 > f.txt with forward button and b.txt
But the Android App is still not working.

I never used unix or any kind of programming and have no clue what to do now.

Edit
Both devices in the same WiFi. Android App IP and PW set from rooting @ Inkpad

[Gentrie]

I got it to Work!

As i wrote on the Inkpad 3 event4 is needed for Button input.

When logged in with SSH write

For Forward
cat/dev/input/event4 > f.txt

Press Forward Button
ctlr+c

For Backward
cat/dev/input/event4 > b.txt

Press Backward Button
ctrl+c

Disconnect with ctlr+d

Download APKstudio to your PC
After installing go to settings/binaries follow all the links there and Download needed Binaries and Link them.

Open Lazypocketbook.apk with APkStudio when prompted decompile everything.
On the left Project window you can see the decompiled APK. Go to Smali/com/wloszynski/lazypocketbook and double click MAINACTIVITY.Smali

Search with Edit/Find f.txt
you will find this

const-string v1, "cat f.txt > /dev/input/event0"

change event0 to event4
The same with b.txt

Save changes.

On left side projects right click main root folder (Default Lazypocketboo.apk-decompiled) and Build APK

Connect your Android device copy over the just created APK.

With your Android Device Download from PlayStore APKSIGNER and sign your just transfered APK. Otherwise install will fail.

Uninstall the old APP and install the New one.
Set IP and Password

Now it should Work.

Correction for Forward and Backward line Command. I forgot a Space after CAT

cat /dev/input/event4 > f.txt

Hi,

What I tested (jb obviously, ssh, smb and ftp) works on a brand new InkPad Color (741) I just got my hands on. I tried it with factory firmware 6.3.250 (20201230_092957).
That is not very surprising actually:
uname -a
Linux pocketbook 3.10.65+ #2 SMP Thu Dec 24 17:07:42 EET 2020 armv7l GNU/Linux
Linux version 3.10.65+ (jenkins@bsp-builder) (gcc version 4.9.2 20140904 (prerelease) (crosstool-NG linaro-1.13.1-4.9-2014.09 - Linaro GCC 4.9-2014.09) ) #2 SMP Thu Dec 24 17:07:42 EET 2020

So it looks very similar as the 740 reported by Marco77 back in 2019.

Hi,

I tried your application v8. When I'm connected to USB with my PB740, USBnet works, ssh, smb,etc too. But when i'm connected only by wifi, I can't access via smb with address \\192.168.1.x . Why?

Hello,
thank you for jailbreak, services and lazy-pocketbook ! Great tool! (It runs on InkPad X)
There is a similar problem with bluetooth. The reader only accepts audio i/o devices. I'm a musician and i want to link my Pageflip-Pedal via bluetooth to the reader (more generally speaking: is it possible to use a bluetooth keypad? This would be great to use the PB as a typewriter :-)) How can i modify/replace the bluetooth driver?
Thank you for your replies !

Greetings.

I tried to pay someone with vastly superior techy skills to mine to connect the Pocketbook to a Raspberry Pi for use as a screen (with a wired and NOT wifi connection), but sadly as yet without success. Below is their report. Would be immensely grateful for advice as to where to go from here.

Theoretical goal: connect an Inkpad 3 (further refered to as "Pad") as an external desktop for a Raspberry Pi 2 (further refered to as "Pi") with no wireless connections.

Things tried:

1) Connecting to the Pi with the Pad using the same Wi-Fi network, so the router itself assigns the required IP & port combination to the Pi to be put into the RemoteInk interface.
●ISSUE: Wi-Fi and the fact that it works so other options not working being more aggravating than they have to be.

2) Streaming the screen from the Pi to the Pad using VNCViewer.
●ISSUE: VNCViewer is not supported by the Pad natively from Google Appstore, crashed on boot when installed from a file.

3) Connecting to the Pad via Secure Shell (SSH) using a non-USBNet cable and then using RemoteInk to connect the 2 devices.
●ISSUE: I am clueless what IP & port the Pi assigns itself while in a SSH connection to intput into the RemoteInk interface. This miiiiight be a lead.

4) Connecting the Pi & Pad together into a network via an Ethernet (female) to MicroUSB (male) adapter for a wired connection.
●ISSUE: Pi does not see the Pad on the other side of the connection, so does not provide an IP & port combination for connecting to the Pi from the RemoteInk interface.

5) Connecting the Pi & Pad together into a network via a USBNet (USB2) cable and a USB2 (female) to MicroUSB (male) adapter and then either getting the described special UI window or inputting the USB_0 network info into the RemoteInk interface. With and without SSH.
●ISSUE: I assume the Pad does not recogize the connection as SSH connection fails and RemoteInk does not offer the expected UI window for an9 USBNet connection, I don't know if its due to a lack of g_ether module on the Pad or if the 3 adapters I tested were all not the right kind. Inputting the IP & port combination forces required Wi-Fi to even attempt the connection. Maybe I have been putting in the wrong port but then I don't know what the right one is.

Is there any way to remove /ebrmain/browser.app or override it or somehow reliably hide it in UI? Thanks!

[stast]

Working good on PocketBook InkPad X (PB1040)

[0xF0F]

Yeah, it works on my PB1040. But the UI is sometimes slaggish now. And sometimes it hangs on powering off with the message "Syncing to pocketbook cloud" but will have to disable that anyway.
Is there a logfile, or other way of debugging/profiling it a little?

Thanks for posting! I have sw_20220201_U741_6.5.1684_user.zip installed on my PB741 and will be giving v8 pbjb-v8-16-g8f1fb88.zip a go presently.

And a massive thank you to @ezdiy for making this! What sdk works for PB741?

[Clort]

For reference, on my linux device (no systemd) I created /etc/udev/rules.d/90-android-tethering.rules

containing

cat /etc/udev/rules.d/90-android-tethering.rules
ACTION=="add|remove", SUBSYSTEM=="net", ATTR{idVendor}=="18d1", ATTR{idProduct}=="0001", ENV{ID_USB_DRIVER}=="rndis_host", SYMLINK+="android"

i found idVendor and idProduct strings with lsusb

Bus 001 Device 060: ID 18d1:0001 Google Inc. Onda V972 (storage access)

After setting up a static /etc/network/interfaces for usb0, ifconfig gives me

usb0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 169.254.0.2 netmask 255.255.255.0 broadcast 169.254.0.255
