PW2 Can you help me make a picture frame from PW2 with broken touchscreen?

[Slackr]

Hi folks

I have a kindle paperwhite 2 (serial begins with 9017), which I'd like to turn into a picture frame.

The touchscreen isn't working since the kindle was dropped last week. There's a hairline crack cutting across the top-left of the screen.

I factory reset the device, so right now it either shows a standard Kindle screensaver, or if I press the power button, it shows a screen listing all the languages I could setup in. If only the touchscreen worked.

I have a USB-to-serial module, which I just tested successfully between my mac and raspberry pi. I assume that I'll need to make a serial connection to the kindle, and have read many posts here about that (thank you all!!).

I need a solution that doesn't rely at all on the touchscreen. I'm a bit lost, but I think what I'd like to do via the serial connection is find the directory with Amazon's standard screensaver images, and replace them with my own images. Nothing more. The device can remain basically stuck in this "ready to be setup" mode forever then, so long as I have my pictures.

But I'm really up for any and all help and advice. Many, many thanks in advance!

That's super -- thank you!

Any suggestions for how I should proceed? I haven't stripped apart the kindle just yet, but I suppose that's the next step. I think tomorrow I'll try the without-solder serial connection method, involving pins and foam and tape.

But I don't know if I should try jailbreak the device, and if so, if that's possible without a working touchscreen.

That's essentially what the ScreenSavers hack does, FWIW ^^.

In which case, serial jb + hotfix + mrpi, and then just run MRPI in a shell instead of via KUAL to install the hack.

Probably want to throw in USBNet in there at one point, to make things easier on you.

Hi again. I hope you can help me some more.

I can't login as root with the password generated in Kindletool-v1.6.5.214.

I've got as far as the diagnostics login, and can login with framework:mario successfully, but not with root:fiona6ce

I'm sure I've got the right serial number -- it's the same one registered on Amazon when I look on my 'Manage your content and devices' page, and also when logging into the device itself with my USB-to-serial adapter.

Any advice, very much appreciated!

[NiLuJe]

The root account is usually locked on *main*, so the password is meaningless there.

As far as *diags* is concerned, recent diags builds may follow the same pattern, I guess? No idea, you'll have to ask people who actually have done a serial jb ;p.

[Slackr]

Thanks for your swift reply!

Yeh, I'm quite sure I'm stuck at the diags login prompt, not main, because I can login there with framework:mario, and just above the login prompt it says:

process '/bin/sh /etc/getty-diags' (pid 1638) exited. Scheduling for restart. starting pid 1648, tty '': '/bin/sh /etc/getty-diags'

Welcome to Kindle!

[Slackr]

update: I've found the root password -- using the password cracking method and file from geekmaster here: http://www.mobileread.mobi/forums/sh...d.php?t=160490 (thank you!)

So I'm IN now. I'll try my best to follow NiLuJe's advice above (serial jb + hotfix + mrpi, and then just run MRPI in a shell instead of via KUAL to install the hack). Wish me luck!

Hi again. I've got root (woohoo!). But I can't get the kindle to mount as a USB drive on my computer. Is there a command I could do, or file I could edit perhaps on the kindle, to force it into USB Mass Storage Device mode?

My Windows and Mac computers can see the device when connected via USB, but don't mount any volumes, and don't give any error. The Windows PC shows a greyed-out volume (F:\) when I right-click on the "Amazon Kindle" device in Devices and Printers. The Mac shows the "Amazon Kindle" in the System Information USB Device Tree, with the following details:

Amazon Kindle:

Product ID: 0x0004
Vendor ID: 0x1949 (Lab126)
Version: 1.00
Serial Number: (REDACTED)
Speed: Up to 480 Mb/sec
Manufacturer: Amazon
Location ID: 0xfa123000 / 8
Current Available (mA): 500
Current Required (mA): 2
Extra Operating Current (mA): 0

[NiLuJe]

From main or from diags? If from diags, how are you actually triggering USBMS?

[Slackr]

This is when I’m in main.

[NiLuJe]

That usually means volumd has its panties in a bunch, which may genuinely happen on its own if you boot the device while it's plugged (don't).

Other than that, USBMS is a weird and wonderful mess on Kindle, so, eh, check the logs, maybe?

[Slackr]

I've just tried rebooting without USB cable connected. Then I logged-in as root, in main. Then I attached the USB cable connecting my kindle to PC. Then I typed the dmesg command, and I see the following at the end:


KERNEL: I pmic:charger chgina::charger connected
otg udc vbus rising wakeup
fsg_suspend:3836
fsg_resume:3894
fsg_disconnect:764

send_online_uevent:669 fsg_ 0x1 recovery_mode:0
g_file_storage gadget: high speed config #1

send_online_uevent:669 fsg_ 0x9 recovery_mode:0


My PC can see the "Amazon Kindle" device in Devices and Printers, but the USB drive (right-clicking and selecting Browse files) is greyed-out.

Any ideas? I think I'm looking for a command to tell the kindle to allow the PC mount the drive.

Another thought I had was... could it be that the Kindle won't let me mount the drive on my PC, because the kindle isn't registered with Amazon? I see there's a com.lab126.amazonRegistrationService isRegistered value in the /usr/sbin/shipping_mode shell script (I'm reading it to try to learn)
