I would use the latest, same file names but instead of using either 21676 or 25697, use 34311. I understand you are already on a higher build (25697>21676) but you must downgrade to upgrade So you would get:

1: Hard Reset 30-30-30 (Factory Defaults, through GUI, don't use the reset button)

2: Flash - K3X_21676_mega_nv60K

3: Hard Reset 30-30-30 (Factory Defaults, through GUI, don't use the reset button)

4: - K3.X_34311_mega_e3000

5: Hard Reset 30-30-30 (Factory Defaults, through GUI, don't use the reset button)

6: reconfigure everything


hello ian5142,

before I flash the K3.X_34311_mega_e3000, I have to flash the K3.x_21676_mega_nv60K first.
Only then can I use the current K3.X version which has no nv60 extension

That is what I would suggest.

Make sure to reset to defaults when flashing a new build (at least until you get to K3X 34311).

seriously ??!!

As you can read (I hope so), I already have a xxx version on the device!
So I can not install K2.6_21676_mini_e3000 !!!
That would destroy the device.
The K2.6_21676_mini_e3000 I can install if I have a Linksys version on the device!
The K2.6_21676_mini_e3000 version is the first version I need to install on an E3000 when I come from the Linksys version !!

So thank you for the nonsensical advice.
If the exact procedure is too much for you, you do not have to write an answer!


If you have a K2.6 build on the device now and are trying to go to K3.x....then you just follow the instructions...

If you don't start with the K2.6_21676_mini_e3000 build... then K2.6_21676_mega.nv60k...it won't upgrade to the K3.x correctly.

Feel free to follow any nonsensical advice you like...but I actually have an E3000 that I've bricked and recovered at least a dozen times now.

With all the posts floating in this thread...exactly what build is currently on your device....it is easy to get lost in it all.

OK...just re-read it again...and I think you have a mega.nv60k build already on it...

so...yes...just load 21676_mega.nv60k and start with Step 2...make sure you load K3.x_21676.mega as step 3.....then upgrade to whatever newer k3.x build you like.

My apologies earlier...I didn't catch that you already had a k2.6_xxx.nv60k installed.

hello together,

Due to a lot of work I was not able to carry out the installation yet. I'll probably do that tomorrow.
Since there are new problems since January and I must to completely renew the router anyway, I would like to ask a question:

there are already current a " K3.xx " versions in which the problem "Meltdown and Spectre " was fixed?

@ redhawk0

all right .... all fine Wink

Meltdown and Spectre only effect Intel, AMD and ARM CPUs. The Linksys E3000 is Broadcom based, it is not affected.

Hello,

I'm came across this thread while searching for replacement firmware that had been patched against KRACK. Thank you to the contributors for the great instructions on how to upgrade to K3.X. I'm coming from non-DD-WRT firmware and the instructions were perfect.

I've upgraded to the Dec 29, 2017 release for the Linksys E3000 (dd-wrt.v24-34311_NEWD-2_K3.x_mega-e3000.bin). Everything has been configured to my liking and things are smooth. However, I have been unable to get HTTPS local/remote Gui access to work. Both Firefox and Chrome time out with Firefox complaining that the "Secure Connection Failed".

This seems to be a TLS or SSL issue that reminds me of when browsers dropped legacy support post-heartbleed. Netstat shows HTTPS listening.

I have also tried the Jan 7 (34411 release). I've performed 30/30/30 resets and Gui default resets.

I have the following questions/concerns:
1. Is the Heartbleed bug present in this firmware?
2. Is KRACK (really) patched in this firmware?
3. Is there a reason for the out-of-date handshake between my browser and the software running on the router (eg: space constraints)?

Thanks in advance

I believe you need to generate an SSL certificate. I would suggest looking at let's encrypt: https://letsencrypt.org/

I would start a new thread (make sure to put something like HTTPS not working in the Subject line).

Thanks. I'll start a new thread. The HTTPS is minor if my other concerns are alleviated:

Are both Heartbleed and KRACK patched in the latest builds? I would expect they would be but I want to be 100% sure. The HTTPS was a flag for me.

KRACK was patched back in ~33600 (33525 for Atheros). Heartbleed way before that, I can't remember.
