The big question would be if they've enabled secure boot or do any other tricks (signed firmwares) to prevent installing a 3rd party firmware like OpenWrt.

3

What I know at the moment is

U-BOOT will compare two firmware partitions
If it is not matched, it will be overwritten from the Firmware2 partition to the Firmware1 partition

4

Some of D-Link's AC models come with newer bootloaders that support (or require?) encrypted firmware, see:

That might play as well.

5

this unit is made by someone called "Friends Technology Co., Ltd"
where the DIR-2660 & other AC one's are made by "Shenzhen Gongjin Electronics Co., Ltd. / China,"
so I'm not sure if they would be simmer in any way
https://fccid.io/NCC/CCAR21LP1000T3
https://fccid.io/NCC/CCAJ19LP6100T7

maybe something here but again i think it's by "Bereau Veritas" so who knows

https://fcc.report/FCC-ID/KA2IRX1860A1/4644219

no firmware update available that i could find

I have backed up the firmware

And D-Link Taiwan official website has a new version of the firmware
But that thing is encrypted
D-Link F*** You

7

ok found the tw firmware
it has the same header & looks the same format as the AC ones

8

well it seemed to decrypt something "can't verify as I don't have the key"
I can't see the header that I would expect to see tho

http://luckys.onmypc.net/openwrt/DIR-X3260/DIRX3260A1_FW101B05_dec.bin

9

I have a firmware backup of my router
Does this help?

10

from what I can tell it's built off openwrt
I'm not used to the mediatek branch for the MT7622
& with out a unit I'm no going deep into it
but you could look at the image you have & compare it to the decrypted file I left there

11

How did you dump this? I have a COVR-X1862 set (two pieces COVR-X1860), and they also have the SHRS header (they are manufactured by the SGE), but with MT7621. MT7622 is ARM based however, similar to ath79 vs. ipq80xx.

Turns out they also changed the AES key, now that decryption is no longer possible with the tool that worked for COVR-C1200, COVR-P2500, DIR878, DIR-1960, DIR-2660, DIR-3060 etc... this has become quite cumbersome.

Since the firmware download is encrypted and the device is using NAND, the only way I could find to dump the firmware was via UART, i.e. using the uboot commands for NAND read (copy from NAND to RAM first), then displaying RAM contents with md, dumping this over UART... took somewhere around 1-2 hours and some scripting to dump the firmware partition :innocent:

looking at the image decryption in ghidra, they came up with some fancy proprietary AES key generation involving something they call base64 interleaving / deinterleaving... But I couldn't reconstruct the actual algorithm, so the next steps for that device will be: Copy the decryption tool and all of the required .so files (trial and error until it runs) to another mt7621 router and run it... this should dump the key to stdout (which is routed to /dev/null during oem update process, not visible on ttyS0)... Hopefully, this will finally allow to flash COVR-X1860 at least via recovery, hoping the bootloader will only AES decrypt and not verify the RSA key (just like DIR2660 and DIR-3060).

I don't dare to believe this might work for that device in a smilar way...

So again, how did you dump the firmware? :blush: would you mind sharing the firmware mtd partition and bootloader?

Looking a the case, this device looks familiar to the new Broadcom devices by D-Link, called EAGLE (they have fancy AI shit built-in :joy: ), so maybe they found a new manufacturer besides Alpha Networks and SGE.

DIR-X1860 firmware uses the same AES keys as DIR-842 / DIR-859, by the way, it is also MT7621 but made by Alpha networks.

Since X3260 hardware specifications are roughly the same as Linksys E8450

So I use E8450 DTS to modify the partition table
Then compile

Then use TFTP to load this initramfs-kernel.bin
(Need to use UART)

Then use LUCI for backup

But if I have a FLASH programmer and a heat gun
I will consider using a FLASH programmer for backup

13

you should be able to pull the unencrypted firmware image from the dump
and see 1st if you can load it to ram like the initramfs image
if that works then I would try to see it its accepted buy a recovery interface
if that is accepted you know if you make openwrt in that form it should work

14

In my bold attempt just now
Found that you can run a tampered bootloader

Maybe can give up all the stock firmware
Use UBI format like E8450

(Because I want to make it easier for me to use TFTP to Write firmware, so I modified bootloader the default IP inside)

16

I was thinking this will have different keys for decryption
but if you have convinced your self you can recover by uploading your dumped firmware file back
time to make your own
you should work towards making an image to flash via the recover interface
but look's like you are on your way :slight_smile:

17

firmwaare backup

Do not use on other X3260, other D-Link models and other brands of routers

p.s.
To use on other X3260, only firmware patition files can be used

It can be used as unencrypted TFTP recovery firmware.

After all, the original factory does not seem to provide unencrypted TFTP recovery firmware

18

Awesome, I couldn't make DIR-X1860 or COVR-X1860 boot an image loaded via tftp (lzma error 1), only the D-Link one extracts fine (until kernel panic when it can't find rootfs).
Image header is also 0xDOODFEED, maybe there's still something wrong with the image format, or SGE used some proprietary lzma modifications...

Thanks, I'll have a look at the crypto stuff when I'm back at my main machine :slight_smile:

19

make sure you are loading the correct image type
initramfs-kernel should not be looking in flash for any files system

20

I gave up

Can roughly make DTS configuration

But firmware mirroring is a bit difficult
Always trigger firmware check

It seems I need to buy an Linksys E8450

I was thinking that this shit thing is the same as the E8450 hardware specification

But the problem on the firmware is a big trouble

I can't do it with my previous experience
