PW4 Ask for effectively preventing OTA update 5.12.x

[Uphantom89]

Hi developers,
It's just happened to me when I turned wifi on & it forced my kindle update from 5.12.4 to 5.12.5. Luckily, I follow snapshot thread and bring back my jailbreak.
The question is, up to now which method should I use to prevent OTA update effectively except totally turn off wifi (because I sometimes have to turn wifi on to get my file from cloud storage - dropbox via Koreader)

Please kindly advise. Thank you

1. You can press the button PREVENT OTA Updates in KUAL Helper+ (no guarantee)
2. You can downgrade the firmware below 5.12.* where the above works for sure
3. You can fill the device storage up to less than 200 MB free space

You can also attempt to hobble the OTA backend.

I did try 1st method but no luck, the kindle upgrade itself to 5.12.5
2nd method: do you mean the method of Ilovejedd (in private support) which allow PW4 to downgrade . It's also a good choice for me as 5.12.5 didn't make me interest in.
But let me try method which NiLuJe mentioned above first.

3rd method: honestly, I don't prefer this method.

I'm sure this topic is interested by many members.
Thank you for your advice

The latest hotfix allows to downgrade to initial factory firmware (we have it 5.10.1.3) from 5.12.2-5.12.4.
Nobody has reported if this works for 5.12.5. Just try, install the hotfix once more, copy iff 5.10.1.3 to the usb-root and update via menu.

If I’m running 5.11.1 on my jailbroken Kindle...Is there any reason at all to upgrade to a newer firmware version or not ? It's working pretty well for me

I don't see the different between 5.11.1 and 5.12.5 except the Aa menu.

So, from my point of view, the answer is No

I couldn't downgrade to 5.10.1.3. Error report: invalid update file ; ( I did install the latest hot fix)

Is it initial factory 5.10.1.3 (not customer) for sure?
If so, Amazon might block the downgrade possibility in 5.12.5.

So the only way to downgrade is via Ilovejedd's trick.

Sure that it is factory firmware, I encountered error 007 when installed latest hot fix, so I had to install it via mrpackage. After that , I copied factory firmware into root folder, but kindle said that is invalid file.
So let me downdgrade by Ilovejedd's method
