Hi, I have JB Kindle PW3 (2016). I did JB long time ago, and everything was working great. I am not sure what was my daily driver FW version. May be 5.8.4 or so. Few months ago, I accidentally updated my PW3 to 5.9.7. Since then Kindle launcher does not starts: "Application Error". Although KUAL (I think it is a booklet) runs, and I can start and use KOReader and apps, that I had before. I just would like to see Kindle launcher running again.
Is there any way to roll back to previous FW version? What If I reset a reader, then flash factory_initial_5.7.4.bin (the one that I used to JB my Kindle), then JB once more, install fix and apps, and then update to latest version in which Kindle launcher would work? Is is a good idea or I will end up with a brick? |

@rnb86: Err, what exactly are you calling "Kindle launcher"?
But to answer your question: I'm going with no. When anything mentions a specific version or version range as far as FW 5.x is concerned, assume it's for a very good reason, and honor it. Last edited by NiLuJe; 11-07-2018 at 12:43 AM. |

My Kindles SN starts: G090 G105 ........
Currently FW: 5.9.7 "Kindle launcher" is a book with an egg on it, and a label "Kindle luancher". But also I had a vlasovsoft installed (CoolReader, chess, file manager etc) Now I have to start a book KUAL to start my apps. KUAL has a button to start vlasovsoft too. May be try to flash it with a COM cable? |

You now MUST make the detour via Kual as you already did describe. You can delete the now useless azw2 files for KUAL and Vlasovsoft Launcher. Their icon will remain in your library anyway - IMHO no solution known. You should never-ever have updated to a fw 5.9.x ... by staying with 5.8.11 you'd not have these problems... |

Thank you everyone for response. I have to think before taking risk of downgrading. Also it is different theme, I'd better move to related theme instead of posting here about a downgrading jailbroken PW3. Thanks.
PS: moving here https://www.mobileread.com/forums/sh...d.php?t=288836 and to 4pda.ru |

PW3 5.9.6.1: possible software jailbreak
Big to coplate, knc1, NiLuJe, Branch Delay, et. al. without whom this wouldn't be possible.
I'm copying most of knc1's instructions from the PW3-4, PW3-32, fw-5.8.9.0.1 software jailbreak as the steps are more or less the same. Note, for extracting the packages on Windows, I recommend 7-Zip. This method has only been tested on a single device (PW3 US Wi-Fi without Special Offers). It was installed on a fresh out-of-the-box PW3 with initial firmware of 5.9.6.1 (bought on Cyber Monday deal). It has never been connected to wifi and has never been registered with Amazon (I used the "gift" option). The factory firmware is signed so I believe it may be possible to use this on PW3s that have been OTA upgraded to firmware <= 5.9.6.1. When I copied it to my older PW3 (5.8.11 jailbroken), "Update your Kindle" became accessible instead of automatically deleting the update.bin which is what happens with 5.7.4 and 5.8.9.0.1. I have no intention of upgrading past 5.8.11 on my older PW3s though so I didn't go through with the process and just deleted the renamed update-3314460001-*.bin. This has not been extensively tested and can brick your device. This is only for people willing to use their PW3 as guinea pig. Instructions Spoiler:

Tried on 5.10.1.1: failed, after disconnecting from the computer the bin file was deleted, "Wrong update file" message displayed.

Note: the comment specifically mentioned OTA updates less than or equal to 5.9.6.1. On my Kindle, I went: initial/consumer 5.9.6.1 -> factory 5.9.6.1 -> (manual update) consumer 5.9.6.1 Copying factory 5.9.6.1 back after the manual update, UYK is available and factory firmware got renamed to update-3314460001-*.bin. Didn't try installing it again. I didn't want to tempt fate and I'm too lazy to open up the Kindle for serial jailbreak/firmware flashing should something go wrong. |

One more try on 5.9.7 failed. That's for sure that downgrading is impossible even by a signed factory firmware.
