As far as I can tell the hardware restore function is handled by a software interrupt, meaning the kernel must be up and running for the reset sequence to work. The update overwrites the kernel and bootloader images, meaning that if they go wrong the kernel won't even be loaded. The flashing LEDs are propably a function of the bootloader or even an even lower function from the MX processors internal program memory. So I will speculate that by updating the reader with the wrong firmware, either uboot or the kernel fail to load properly on boot. That means you see the flashing led's, but after that the kernel panics and the software interrupt doesn't work anymore. Restoring the internal sd card with an image also restores the original bootloader and the kernel image. So I was able to do a factory reset after that. The only alternative to that would propably be JTAG debuggung. I found an unused serial port when I opened my kobo (4 vias marked RX,TX,+,GND on the USB side of the PCB), but failed to locate a jtag interface. It must still be on the board somewhere and this post suggests that the individual pins are located on the "down" side of the board. But if I reach the point that I need to resort to JTAG it is really much easier to call on the waranty. Note to Kobo Developer: You are checking the PCB Version of the board in the 10th line or so of rcS script. Would it hurt to run a version check against the Update before unpacking it to the partition!?? Last edited by ichrispa; 01-16-2013 at 06:20 AM. Reason: spelling |

I'd probably be less likely to side load an update in the future and just wait for the official update unless I need to get rid of a major bug or something. |

No problem, thanks for getting back to the question

I definitely have an "old" Touch and it says: FCC ID: ZJLKOBON905 IC: 8912A-KOBON905 MODEL: N905 (obviously) Yes please! |

You don't necessarily need to open it. If my assumption of the SD Card containing a serial number incl the manufacturing date is true, try doing

My model number is N905B, any idea what download of 2.3.2 I should use?
Just done the device manager thing and PID is 4163 and 2.3.1 rev 0110 Thanks. Last edited by Chocky; 01-16-2013 at 03:03 PM. |

Depending on how expirienced you are with hacking you Kobo I suggest that you don't update for now.
If you know how to create an sdcard image and are familiar with restoring disk images try to use the Kobo Touch update. Be prepared to go through the entire restore ordeal though. |

OR You could test which firmware you get by factory resetting, and then doing the setup via the Desktop software, and monitor which firmware link is used to load 2.3.1. I forget where people find this link in their Desktop app cache files probably. But once you have the link you could compare it with the links given here in this thread: if it's the Touch's, use the Touch's 2.3.2; if it's the Glo's, use the Glo's 2.3.2 |

What this does is to update the userland binaries, such as the reader apps. This is what I did and PDF's are finally readable. What will not be updates is the kernel an uboot, so the power consumption issues are ony mildly better. On the other hand, it won't ruin your Kobo Touch... even if it needs Glo Firmware. |

I can't find it anywhere on my Kobo, even with a search for KoboRoot. |

If you copy that file to your .kobo folder on the kobo, it will use it to update itself, then delete the file. After you updated successfully, there should be no KoboRoot.tgz in your .kobo folder anymore. |

Ah, OK.
Thanks for the explanation. Just searched my PC and it comes up with 2 files KoboRoot (zip file) 20/12/2012 65.7Mb KoboRoot (zip file) 01/10/2012 61.7Mb Also, clicking on the kobo-update-2 zip file the KoboRoot.tgz (zip file) is 68.9Mb So I assume I have the Touch firmware.
