K5 Downgrading kindle K5

[apple900]

I messed up, I jailbroke my Kindle K5 (b011) and didn't turn off auto update correctly. So now I have Kindle firmware 5.3.7.3 . I believe this is the reason for some of the problems I am having with KOreader. I noticed there is a downgrader for the K5 but I don't know what firmware to downgrade to and where to get it. so I'm looking for what firmware I should downgrade my K5 to. Thank you

I also do not know what firmware is recommended for jailbreak and was confused by 3-digit and 4-digit firmware numbers. I was under the impression I should get firmware pre 5.12.x but my current one is 5.3.7.3 also I couldn't find any firmware such as 5.11.x to download

I found it in one of the jailbreak guides and will be downgrading it to 5.11.2

You have a "Kindle Touch", software updates for that Kindle model stopped at 5.3.7.3. So you can't update to a 5.11 since that doesn't exist for you Kindle model. Similarly how Kindle Paperwhite 3 (aka Paperwhite 7th gen in Amazon's nomenclature) supports ended with 5.16.2 or PW1's with 5.6.1.1.

This is the jailbreak thread and method that applies to your device and its current firmware:

Before re-doing jailbreak you should probably first try to just install the latest hotfix bin (from the snapshots thread) using "Update Your Kindle" option and then check if KUAL and KOReader run correctly.

So, you'd device is already at the latest (a last it ever got) firmware for that model.
And 5.11.x is newer firmware than 5.3.x.y ( 11 > 3) so installing that (if it were ever possible for your Kindle model, and it isn't) would not be a "downgrade" but an "upgrade".

Since there is a working jailbreak method for your firmware there isn't even a need to do any sort of downgrade.
