How to find firmware version from shell prompt

tamr · 05-31-2015, 04:29 AM

Hi,

I have a K3W.

I know how to find the firmware version when my Kindle is in its normal "reader" mode by going to Home->Menu->Settings. What shows up there is 3.4.1 (2540470001) so I know I have the latest version.

How do I find the same info via a shell session?

I've looked at /proc/cpuinfo, uname, and dmesg but don't see it there.

you can look at the source code of the jailbreak.

you could also look at /etc/version and /etc/pretty-version

Thank you both for your replies.

Here's what I get:

Code:

[root@kindle /etc]# cat prettyversion.txt
Kindle 3.4.1 (~~otaVersion~~)

[root@kindle /etc]# cat version.txt
System Software Version: 001-S401_luigi-254047
Tue Nov 25 18:48:40 UTC 2014
[root@kindle /etc]#

The odd thing is that Settings shows three zeroes: ...70001. But it's close enough.

@tamr:

A-B-C -> C0A

(Where A & C are [:digit:] and B is [[:alnum:]_])

(Don't ask me why ;D)

[Caveat: Mostly holds true. May not always hold on some weird device/firmware/main/diags builds].

We generally don't give a crap about OTA build numbers, and a far safer method to get it is to check the headers (OTA target) of the update package for said version.

Code:

kindletool convert -i ~/Downloads/Update_kindle_3.4.1_B006.bin                                                                                                                                                                        ──(Sun, May 31)─┘

Thanks @NiLuJe, I'll add this to my notes on how to get the build version.
