ASUS ROUTERS CFE DUMPS COLLECTION

Ok, thank you for the info. What's your AC66U CFE version?

 

quick question.

can I dump my CFE, edit it to GB for the UK region I live in and flash it again without any issues?

 

Yes you can.

 

Thanks, I changed the 2 EU to GB, saves in notepadd++ but get this

Code:

Unknown CFE version. Update canceled for safety reasons.

I tried to get the CFE update utility but the link here http://forums.smallnetbuilder.com/showpost.php?p=130163&postcount=11 times out

Googling CFE update utility isn't much help either, don't suppose you have a link to the util do you please?

 

set mine to 1600,666 and locked up

router.
power+WPS to erase NVRAM
reboot
reload .cfg file
reboot
working again
1600,666 does NOT work for me.

You cannot do that, you must use HXD or other hexadecimal program.

The link to CFE Script Update is working fine, here you have it:

http://files.ryzhov-al.ru/Routers/RT-N66U_CFE_update/cfe_n66u-1.0.1.9.tgz

You shold read better instructions before you try to update CFE or you will end with your router bricked.

What router model are you trying to update and from which version?

 

philmiami, you will need luck to get a AC68U that allows 1600MHZ overclock.

 

All out of luck today.....
router went FUBAR
like I posted, WPS switch and power on/off to reset NVRAM
so my router does NOT do 1600

 

Thanks, I had read that but used the same command used to flash to a newer CFE, I had updated my N66u from 1.0.1.3 to 1.0.1.9 and have now dumped, edited EU to GB and reflashed 1.0.1.9 but have not factory reset yet to see if the GB code forces it to the GB settings or not.

I have a 68U I will do the same to 1st as thats an AP and easier to set back up.

 

1.0.1.4.

Anyway, have managed to flash the cfe via the following and Merlin 376.44 beta 3 correctly populates the 5GHz channel options.

Does the above insert the correct CRC?

 

No, it just flashes CFE image from a file. The NVRAM area inside of CFE image (cfe.mod) must include right CRC check sum.

 

Any utility which automatically inserts the correct checksum?

 

Ok,

So, what is the exact procedure to change CFE from 1.0.1.6 (US) - 1.0.1.6 (EU) in RT-AC68U and other way ? What tool to be used to achieve that ? It's easy to dump CFE and edit with some HEX editor, but not quite obvious how to put it back. Has anybody did that an succeeded ?

 

after editting the cfe, copy the mtd-write binary from the asus ac68 utility to the router and execute; mtd-write file boot
(replacing file with the path to your cfe)

(thanks hggomes)

2 things to note:
- don't try with mtd-write2, which you may get via auto-complete
- this works for the ac56r/u and can be used to unlock mem overclocking for those on a cfe that disables it. however, be sure to test cpu and mem oc independently. if you can't do 1600,533, do not try at 1600,800. - RIP ac56r.

 

Please update your mirror with all new files, i sugest you to overwrite them all because there was some small fixes done in two CFE's.

Total files = 19

Thank you.

 

If you want to make a tar of everything I can download / mirror it on my build server also.

Might also want to add 1.5 as a HW Version for the AC66U

http://puu.sh/aBKwt/4e29c1b90a.png

 

I only wondered whether is possible to do it before I change anything. Only for sure, that's all.

 

Four new CFE's added:

RT-N18U 2.0.0.7 (US)
RT-AC66U 1.0.1.7 (US)
RT-AC56U 1.0.2.8 (US)
RT-AC68U 1.0.2.0 (US)

 

Hi,

I compared the AC66U EU and US downloads on the first page. Noted that there is a difference in the regrev values.

From a quick Google, Asus or Broadcom uses a combination of variables: ccode, country_code and regrev, maybe others as well, to implement regional restrictions.

Anyone familiar with what regrev specifically affects?

 

According to the source for the AC68U the following values are used;
