(-_-) : you would need development tools and headers to compile yourself. just download and use a readily compiled version. like the one in the OP or the version that dsmid compiled and packaged.

Thanks, that might make it a little easier.
I unzipped the compiled version, along with with libusbx in a folder with it. I see: 'shell script', 'perl script' and 'unknown' file types. But I can not figure out how to run the k3flasher program.... I'm sure I need the terminal here. I've fiddled with it for a while, but I still have to ask for help. Sorry for dumb questions... How do I start the program? . (ubuntu) |

You must do that BEFORE you put your device in USB Downloader mode more completely you can try reading through: a "worked example" is HERE (doing something a bit different that what you intend, no doubt. but all the commands you might need are there.)

(-_-): You need a terminal window and you'll have to use the shell. Switch to the path where the k3flasher binary is stored. Make sure it can be executed: "chmod +x k3flasher". Make a backup of the current state of your device, no matter if it is broken. Call the backup script in order to do so: "sh k3-backup.sh", or better, dpavlin's included Perl script: "perl k3flasher-incremental-backup.pl". Then use k3flasher to write a clean rootfs, kernel or bootloader (depending on what is broken).

K3Flasher reset returns memset error: 0x56787856
I have a Kindle 3 3G/Wifi I've been trying to debrick with K3Flasher. When I try to use the K3Flasher reset option I get:
Code:
$ sudo ./k3flasher mx35to2_mmc.bin reset I: found suitable device E: wrong transfer length, wanted to receive 8 bytes but received 4 bytes. I: above error can be ignored, it's due to the device being in ROM kernel mode E: kindle reported a memset error: 0x56787856 E: error when initializing SoC registers E: aborting. It is suggested you power-cycle the device. Code:
$ sudo ./k3flasher mx35to2_mmc.bin info I: found suitable device E: wrong transfer length, wanted to receive 8 bytes but received 4 bytes. I: above error can be ignored, it's due to the device being in ROM kernel mode I: RAM kernel should be running now. Trying to re-open device: . I: got it. I: read info E: wrong transfer length, wanted to receive 8 bytes but received 4 bytes. E: aborting. It is suggested you power-cycle the device. Any advice on next steps I should take? Feel free to reply with any questions. |

Have you tried Kubrick?

Many thanks for your quick reply!
I tried Kubrick before K3Flasher: Kubrick finds the Kindle 3 and completes without error, but the two flash programming steps occur too quickly: where the first flash should take 10-30 seconds and the second flash several hours, both complete in a few seconds. I also tried Freescale's ATK on a couple of different Windows machines and it returns a "can't find USB device" error. On these forums it says that this occurs when the USB device drivers didn't install, that's why I tried it on two different Windows machines (XP and Windows 7.) On both machines Windows sees the Kindle 3 as "SE Blank Ringo" so I seem to be able to put the Kindle into USB downloader mode. Keep those questions coming! |

Your device doesn't seem to keep running the RAM kernel but rather stays in a close reboot loop. This indicates hardware failure. You can rule out flash memory and external devices like e.g. the e-ink screen and driver. Most likely it is power or RAM related. Since you ruled out power, I guess there's not much hope.... :-(

Okay: So I have used k3flasher now a little over 100 times on about as many devices.
EDIT: It's been a while since I did the last lot but I did 3 today so far. Feedback: works perfectly for new demo devices. Bugbear: On devices that have been left on display since time immemorial (that's a long time by the way my non-UK friends) it appears to trash the device. This has happened 7 time out of 100 now. (1 out of the 3 today) Here's a snippet from the end of one of these times: THE COMMANDS: (not a big fan of typing things twice... so... yeah) Code:
sudo ./k3flasher ./mx35to2_mmc.bin program rootfs ./mmcblk0p1-3.4+jb+keys.img ; sudo ./k3flasher ./mx35to2_mmc.bin info ; sudo ./k3flasher ./mx35to2_mmc.bin reset The final output: Code:
I: flashed 0x001e0000 (=1966080) bytes I: flashed 0x001f0000 (=2031616) bytes I: flashed 0x00200000 (=2097152) bytes I: flashing of 0x00200000 (=2097152) bytes complete I: offset 0x28a00000 continue_address 0x28dc1000 100.00% I: writing 0x00007000 (=28672) bytes to address 0x28dc1000, waiting for completion... I: wrote 0x00007000 (=28672) bytes, waiting for completion... I: flashing of 0x00007000 (=28672) bytes complete I: offset 0x28a07000 continue_address 0x28dc8000 100.00% [sudo] password for twobob: I: found suitable device I: read info I: got size 1048576 (probably wrong) I: downloading 0x00000200 (=512) bytes, starting at 0x00040c00 I: DO NOT MAKE THE FOLLOWING INFORMATION PUBLIC! I: if you need to discuss it in public, obfuscate I: e.g. the second half of the numbers. I: got device serial number <B00ZZ0Z000999999> I: got device Wifi MAC <99ZZ9999999Z> I: found suitable device I: resetting device. EDIT: (So you can see everything looks fine at this point) And then after removing the power cable, and power cycling with the switch the device show a permanent green power light and will do nothing else. I have one of these devices in this state actually here at the moment. So, Yeah, excellent product, just wanted to share my experiences with the odd few bad-uns. Any clues on magicking up a working device from the toastie ones would be cool Respect to Hawhill for providing this awesome tool btw. EDIT: Err yeah you really need more details from me, I'll try to think of some tests tomorrow that I can manage

Not that it will probably help, but I would indeed be interested in what the behaviour is when it is put into download mode again (does this even work?) and how k3flasher behaves on a second try...
Thanks for the kudos, much appreciated. My K3 is long gone, I've made it a gift after getting a KPW and then it died by an unfortunate accident (to be exact, the screen died). So this software project lives on even when the device is long dead :-) (good thing it does work pretty reliable, I now have nothing to debug it, though I could probably get back the remains of the K3). |

Then that is most likely a "development prototype" board. Translation: All bets are off. |

Okay... so it goes back into USBDOWNLOADER mode.
and INFO reports correctly? Does it charge in this mode? Because the "Other mode" (full green light) just dumps the charging as far as I can tell... Gonna be tough to get it to have enough charge otherwise to try for a second attempt.... Any ideas anyone? EDIT: One final question: sudo ./k3flasher ./mx35to2_mmc.bin reset I: found suitable device I: resetting device. would THAT put it into a charging state? I have never been clear what that is supposed to do. (since nothing visibly happens) I would hazard a guess that it switches to the default "mode". So charging maybe?
