Firmware Update 4.1.2

New firmware update http://www.amazon.in/gp/help/custome...deId=200774090 is it jailbreak friendly?

patrickt · 01-25-2015, 06:51 AM

And that's a firmware update for "The Kindle"?

This may be for an older kindle.

I suspect the OP has no idea that Mobileread's members have different Kindles and that different Kindle versions exist; otherwise, he would have been much clearer than to simply state that a new firmware version exists for a kindle.

Additionally, the Subject Heading is quite ambiguous.

Be careful of these types of posts, please.

Oh man, I thought they would leave these older Kindles alone. The patch says this is for "security improvements." Does that mean they want to lock the Kindle 4 down more "securely" so hacks won't work? For now I've turned off my WiFi. Is there any way to keep the Kindle from updating? -- at least until I know a little more about this update?

Pretty small update, this isn't exactly one of the new full system images.

Here are the patch files, as revealed by kindletool.

Code:

" tar.vim version v29
" Browsing tarfile /home/eschwartz/Downloads/Kindle Hacks/Update_kindle_4.1.2/update-patches.tar.gz
" Select a file with cursor and press ENTER

000.prettyversion.txt.patch
001.ca-certificates.crt.patch
002.version.txt.patch
003.cacerts.patch
004.libcurl.so.5.2.0.patch
005.libsoup-2.4.so.1.3.0.patch

Okay, so -- basically -- don't worry about it and just let it update?

I assume so. The targets seem to be fairly reasonable.

Unless you suspect Amazon can pwn you through patching cacerts, libsoup and libcurl. That seems to be the only changes outside the version number.

Hi there, would it be safe to try to jailbreak a kindle 4 NT that already has been updated to 4.1.2? Could I use the previous jailbreak? Could that brick the kindle?
