Some relevant logs from IRC (Thursday, June 23):

Spoiler:

1:08:53 PM - damon12: hi. I may have broken eMMC in my Kindle Paperwhite 3, just curious if anyone has Kindle Paperwhite 3 partition dump for share
1:09:23 PM - damon12: million thanks
1:09:59 PM - staphoent: i have a pw3, wouldnt have a clue how to share that though
1:11:07 PM - Glorfindel is now known as Glorfindel-gone.
1:12:32 PM - damon12: If it is jail-broken and has usbnet installed, you may access it by SSH, dump the partition by dd and save to /mnt/us, then use scp to copy
1:14:05 PM - damon12: If it is not jail-broken but you have TTL, you may boot into DIAGS mode, use dd to dump to mnt/us, then boot back to main mode and copy by usb cable
1:14:26 PM - staphoent: lol it is jail-broken, has usb net installed, dont know how to access by ssh, dont know how to dump by dd or use scp
1:16:02 PM - damon12: let me write a quick tutorial
1:16:16 PM - staphoent: go ahead
1:17:43 PM - damon12: forgot it is already written here
1:17:43 PM - damon12: https://wiki.mobileread.com/wiki/Kind...USB_Networking
1:18:00 PM - damon12: are you using Linux or Mac or Windows?
1:18:23 PM - staphoent: mac
1:18:38 PM - staphoent: i already have usb networking up and running
1:19:39 PM - damon12: does "ssh root@192.168.15.244" in terminal show something?
1:20:51 PM - damon12: password is either blank or "mario" (without quotes)
1:21:30 PM - staphoent: i have it set up to this stage= [root@kindle /]#
1:21:50 PM - damon12: then please type this
1:22:01 PM - damon12: dd /dev/mmcblk0p1 /mnt/us/p1.img
1:22:09 PM - damon12: it may takes a while
1:22:47 PM - staphoent: just gives me a list of options
1:23:38 PM - staphoent: [root@kindle /]# dd /dev/mmcblk0p1 /mnt/us/p1.img BusyBox v1.17.1 (2016-04-17 11:24:55 PDT) multi-call binary. Usage: dd [if=FILE] [of=FILE] [bs=N] [count=N] [skip=N] [seek=N] Copy a file with converting and formatting Options: if=FILE Read from FILE instead of stdin of=FILE Write to FILE instead of stdout bs=N Read and write N bytes at a time count=N Co
1:24:29 PM - damon12: sorry, my bad
1:24:40 PM - damon12: should be this
1:24:40 PM - damon12: dd if=/dev/mmcblk0p1 of=/mnt/us/p1.img
1:25:10 PM - damon12: after this one is finished, then please run these two also
1:25:14 PM - damon12: dd if=/dev/mmcblk0p2 of=/mnt/us/p2.img
1:25:17 PM - damon12: dd if=/dev/mmcblk0p3 of=/mnt/us/p3.img
1:26:08 PM - damon12: One remindar, I assume you have at least 700M free space.
1:26:28 PM - damon12: For new Kindle, it should be around 2G free
1:28:41 PM - damon12: After all commands have been finished, please enter "exit" to quit ssh
1:29:23 PM - staphoent: how can i check my space through usb networking
1:29:30 PM - staphoent: as i do have a lot of files on there
1:30:22 PM - damon12: you may "cd /mnt/us", then "df -h ."
1:31:04 PM - damon12: It should show you how many space left (hopefully my memory is correct)
1:34:04 PM - staphoent: i guess im looking at mnt/base-us?
1:35:30 PM - damon12: would you copy what you see when running "mount"
1:35:56 PM - damon12: sorry, my PW3 is broken and I can't confirm if it should be "mnt/base-us" or "mnt/us"
1:36:11 PM - damon12: "mount" should give me some hints
1:36:32 PM - staphoent: [root@kindle /]# cd /mnt/us [root@kindle us]# df -h Filesystem Size Used Available Use% Mounted on /dev/root 437.4M 314.8M 100.6M 76% / tmpfs 251.4M 100.0K 251.3M 0% /dev tmpfs 251.4M 0 251.4M 0% /dev/shm tmpfs 32.0M 1.8M 30.2M 6% /var /dev/loop/2 2.5M 2.5M 0 100% /usr/share/X11
1:38:58 PM - damon12: does "df -h ." work?
1:39:04 PM - damon12: (there is a dot at the end)
1:40:33 PM - staphoent: it says use 31%
1:40:36 PM - staphoent: should be fine then
1:41:17 PM - staphoent: want me to run those commands u sent me?
1:41:40 PM - damon12: yes, please
1:42:14 PM - staphoent: ran first one but nothing happening atm
1:42:49 PM - damon12: so it finished in a few seconds?
1:42:58 PM - staphoent: no jsut displayed a blank line
1:43:47 PM - damon12: does it show the prompt "[root@kindle us]" under the command you type?
1:43:54 PM - staphoent: no
1:44:02 PM - staphoent: not responding to anything with that
1:44:03 PM - damon12: then it is running, be patient
1:44:31 PM - staphoent: [root@kindle /]# dd if=/dev/mmcblk0p1 of=/mnt/us/p1.img
1:44:38 PM - staphoent: then two blank lines
1:45:24 PM - damon12: the first file will be around 500M, so it takes some times
1:45:41 PM - damon12: the second and third will be much smaller
1:45:44 PM - staphoent: how did you break your emmc?
1:46:44 PM - damon12: not sure, I SSHed my kindle and install some programs, change boot logo and try to add custom language. Then after restart, it can't open any books
1:47:01 PM - staphoent: lol
1:47:14 PM - staphoent: are you tempted by the oasis?
1:47:53 PM - damon12: and usbnet never start again, so I use TTL to "fix" it
1:48:08 PM - staphoent: 921600+0 records in 921600+0 records out 471859200 bytes (450.0MB) copied, 351.452832 seconds, 1.3MB/s
1:48:38 PM - damon12: after some trials, it stucks at bootloader and said cannot access the flash chip
1:48:45 PM - staphoent: thats annoying
1:48:49 PM - staphoent: run the second ?
1:49:04 PM - damon12: yes please
1:49:21 PM - damon12: and my PW3 cannot enter fast boot mode too
1:49:35 PM - staphoent: ahh right, and these image files will fix that?
1:49:58 PM - staphoent: [root@kindle /]# dd if=/dev/mmcblk0p2 of=/mnt/us/p2.img 131072+0 records in 131072+0 records out 67108864 bytes (64.0MB) copied, 38.205392 seconds, 1.7MB/s [root@kindle /]#
1:50:20 PM - damon12: the file should be able to fix it if my flash chip is just corrupted.
1:50:28 PM - staphoent: ok
1:50:40 PM - damon12: but if it is physically damaged (e.g. electrostatic shock), I will need a new chip
1:50:41 PM - staphoent: do you know much about how the pw3 system works?
1:50:47 PM - damon12: but I need the files anyway
1:50:50 PM - staphoent: ok
1:50:57 PM - damon12: I am quite new to linux
1:51:03 PM - staphoent: ahh right
1:51:16 PM - damon12: only know it depends strongly on webkit and pillow
1:51:33 PM - staphoent: im trying desperately to disable the flash to black/update function on my pw3
1:51:37 PM - staphoent: but having a nightmare
1:51:43 PM - staphoent: all three have finished
1:52:08 PM - damon12: then please enter "exit"
1:52:17 PM - damon12: finally, these three
1:52:20 PM - damon12: scp root@192.168.15.244:/mnt/p1.img $HOME/Desktop/p1.img
1:52:29 PM - damon12: scp root@192.168.15.244:/mnt/p2.img $HOME/Desktop/p2.img
1:52:31 PM - damon12: scp root@192.168.15.244:/mnt/p3.img $HOME/Desktop/p3.img
1:52:52 PM - damon12: After all finished, you should see three files appear in your Deskop
1:53:01 PM - staphoent: port 22 conection refused
1:53:31 PM - damon12: are you under Terminal? (not ssh)
1:53:43 PM - staphoent: Users-Mac-mini:~ user$
1:55:40 PM - damon12: you are in the right place. but not sure why it shows error
1:55:49 PM - damon12: give me a few minutes
1:55:55 PM - staphoent: k
1:57:40 PM - damon12: just curious if you can connect the Kindle in "USB Mass Storage Mode"?
1:58:05 PM - damon12: (i.e. It appears as a flash drive in your Mac)
1:58:29 PM - staphoent: i can connect it as i normally do i.e to load pdfs through usb
1:58:36 PM - staphoent: but will that display the img files?
1:59:05 PM - damon12: yes, it should show that 3 files you just created
1:59:58 PM - staphoent: ok got them
2:00:58 PM - damon12: then please zip all of them in one file, and upload to any free file hosting site, and send me the link. Thank you for your help
2:01:11 PM - damon12: Btw, you may keep those files just in case your friends need them
2:01:59 PM - staphoent: can i use that dd thing to download the rest of the system files from my kindle?
2:02:07 PM - damon12: The img file will NOT contain any of your personal information (e.g. S/N etc), so it is safe to share it.
2:02:08 PM - staphoent: i really want to look at some of the configuration files
2:02:35 PM - damon12: p1.img and p2.img contains the system files
2:02:42 PM - damon12: you may play with it, but with care
2:02:57 PM - staphoent: as in configurations for the waveforms of the screen?
2:03:55 PM - damon12: p3.img is the file for rescue mode. I don't recommend touching it.
2:04:19 PM - damon12: yes, should be in p1 or p2
2:04:39 PM - staphoent: ok
2:04:49 PM - staphoent: its not letting me take p1 from thek indle
2:04:57 PM - staphoent: it says error 36 cannot be read
2:05:31 PM - damon12: oh....
2:06:04 PM - staphoent: how do i open/look inside these files
2:06:11 PM - damon12: what is the file size?
2:06:48 PM - damon12: you may mount it under Linux, I guess MacOSX should work too
2:06:59 PM - staphoent: 471.9
2:07:17 PM - damon12: Would you try copying again?
2:07:34 PM - staphoent: yeah i can try
2:07:41 PM - staphoent: its not letting memoun them in mac
2:08:05 PM - damon12: so all three files failed?
2:08:23 PM - staphoent: what i mean is, in kterm in my kindle i can find lots of configureation files under /mnt-us/proc
2:08:30 PM - staphoent: id like to look at them on my comp
2:08:30 PM - staphoent: no
2:08:34 PM - staphoent: just the first one
2:08:37 PM - staphoent: the other two i can copy
2:10:29 PM - damon12: sorry then we may need to create the first file again
2:10:32 PM - damon12: ssh root@192.168.15.244
2:10:36 PM - damon12: dd if=/dev/mmcblk0p1 of=/mnt/us/p1.img
2:10:48 PM - staphoent: it says [root@kindle kvncviewer]# dd if=/dev/mmcblk0p1 of=/mnt/us/p1.img dd: writing '/mnt/us/p1.img': Read-only file system 1+0 records in 0+0 records out 0 bytes (0B) copied, 0.118817 seconds, 0B/s [root@kindle kvncviewer]# dd if=/dev/mmcblk0p1 of=/mnt/us/p1.img dd: can't open '/mnt/us/p1.img': Stale file handle [root@kindle kvncviewer]#
2:11:10 PM - damon12: dd if=/dev/mmcblk0p1 of=/mnt/us/p1a.img
2:11:19 PM - damon12: this time let's call the file "p1a.img"
2:11:34 PM - damon12: probably MacOSX locked the file p1.img up
2:11:49 PM - staphoent: can you delete the last one from here, because i may not have enough space now
2:11:57 PM - damon12: ohh, yes
2:12:07 PM - damon12: you can delete p1.img, p2.img and p3.img
2:12:16 PM - damon12: since p1.img is broken, p2 and p3 already copied
2:12:23 PM - staphoent: well then i have to go back to usb storage mode
2:12:30 PM - staphoent: is there anyway to delete it through shh
2:12:36 PM - damon12: yes
2:12:49 PM - damon12: rm -rf /mnt/us/p1.img
2:13:05 PM - staphoent: rm: can't stat '/mnt/us/p1.img': Stale file handle
2:13:46 PM - staphoent: you know u can downlaod the whole firmware form amazons website
2:15:06 PM - damon12: it seems the p1.img has been deleted but Linux does not know
2:15:10 PM - damon12: It should be safe to proceed
2:15:29 PM - damon12: I guess those firmware from amazon contains updates only. Not complete image
2:15:46 PM - damon12: would you advise the link so I can have a look?
2:16:06 PM - staphoent: dd: can't open '/mnt/us/p1a.img': Stale file handle
2:16:31 PM - damon12: then you may need to run fsck under MacOSX
2:16:50 PM - damon12: to fix the possible filesystem problem
2:16:50 PM - staphoent: http://www.amazon.com/gp/help/custom...deId=200203720
2:16:52 PM - staphoent: a few pages down
2:16:58 PM - staphoent: filesystem problem?
2:17:30 PM - damon12: yes, FAT partition is easily corrupted
2:17:48 PM - damon12: yes, FAT partition can be easily corrupted
2:18:48 PM - damon12: Sorry that it is 2:18am now, I have to go bed and wish to see you soon.
2:19:24 PM - staphoent: is that a problem with my kindle?
2:19:31 PM - staphoent: or just the files u put on there
3:34:31 PM - eschwartz: damon12: The firmware update images contain the whole rootfs for the main system, but they don't contain the diags partition or the bootloader code.
3:35:08 PM - eschwartz: I see you found MadMAXXX's "Unbrick a PW3 (Fastboot)" thread.
3:35:46 PM - staphoent: i think hes sleeping lol
3:41:12 PM - eschwartz: So he will be able to catch up when he reconnects, no big deal.
3:41:46 PM - eschwartz: damon12 has a working uboot, according to the MobileRead thread.
3:41:56 PM - staphoent: ah cool
3:42:09 PM - eschwartz: So all he needs (I think) is a diags kernel + image
3:42:21 PM - staphoent: how do you stay logged when ur computers off?
3:42:35 PM - eschwartz: Then he can boot to that and flash the main rootfs.img extracted from a standard Amazon update.
3:42:46 PM - eschwartz: You don't have to turn your computer off.
3:42:57 PM - staphoent: are those the image files he was getting me to obtain?
3:42:58 PM - eschwartz: Or you can use a bouncer to keep you connected.
3:43:01 PM - staphoent: ahhh ok
3:43:09 PM - staphoent: got you
3:43:23 PM - eschwartz: mmcblk0p1 is rootfs.img so you can skip that, actually.
3:43:31 PM - staphoent: ok
3:43:36 PM - staphoent: ive got the other two
3:43:42 PM - staphoent: if he still needs them
3:44:03 PM - eschwartz: mmcblk0p2 should be the diags partition.

Particularly:

1:45:44 PM - staphoent: how did you break your emmc?
1:46:44 PM - damon12: not sure, I SSHed my kindle and install some programs, change boot logo and try to add custom language. Then after restart, it can't open any books
1:47:53 PM - damon12: and usbnet never start again, so I use TTL to "fix" it
1:48:38 PM - damon12: after some trials, it stucks at bootloader and said cannot access the flash chip

Not that it matters how that partition got corrupted, of course.

...

@damon12,

staphoent is still hanging out on IRC, and he says he got the necessary partition image copied for you. But you haven't revisited there after asking...
