Request for infos: Jailbreak Kindle PW2 5.12.2.1.1
5.12.2.1.1 is the lastest Firmeware version of the Kindle Paperwhite 2.
I precisely have the PW2, PW2IL (serial 9017). To jailbreak a PW2 you first need to downgrade it. When trying to downgrade the Firmeware using this method, the downloaded Firmware (update_PW2_5.4.3.2_initial.bin) is deleted by the Kindle as soon as the USB device is ejected. I was hoping to jailbreak my Kindle so I could install Koreader. I looked at a lot of posts and wikis and I could not find a clear information about the state of the yet non-jailbreak and up to date PW2. I figured there is no known way to jailbreak those old models. I am posting here so I can get any additional info I would have missed and so people looking for the information can refer to this post in the future. |

For 5.12.2.1.1, and anything between 5.10.3 and 5.13.3 (inclusive) should try this KindleBreak JB https://www.mobileread.com/forums/sh....php?p=4105735. This JB method doesn't require software rollback at all.
BTW, firmware version 5.8.8 or later won't allow you to install an earlier software update. Last edited by tekkasit; 03-20-2023 at 11:11 AM. |

In January I was able to jailbreak my Kindle PW2 5.12.2.1.1 with the "KindleBreak <= 5.13.3" https://www.mobileread.com/forums/sh....php?p=4105735
I installed KOreader and was happily reading. Unfortunately my Kindle updated itself to 5.12.2.2 and the JB got lost, KUAL did not start anymore. I resetted my Kindle PW2 and tried the "WatchThis JB <= 5.14.2" https://www.mobileread.com/forums/sh...ndle+jailbreak But this did not work. After being in DEMO Mode and "Sideload Content -> Done" I was stuck. The script did not start at all and the jailbread therefore was not working. Then I registered my Kindle again and tried the "KindleBreak" again. With no luck. After following the instructions and putting in "file:///mnt/us/kindlebreak.html" I just got the feedback that the search did not find anything. No jailbraking. Seems that 5.12.2.2 has been patched against the vulnerability of 5.12.2.1.1 I checked all information I could find regarding PW2 and 5.12.2.2 but the results were not consistent. Even after searching I am not sure if it is possible to JB PW2 on 5.12.2.2. My question: was anybody successfull with a JB on a Kindle PW2 on 5.12.2.2? If yes which method? What was the trick to be successful? I miss my KOreader - any help would be appreciated! |
