I bricked my DIR-895L. Hope someone can make a backup "CFE.BIN" of DIR-895L and share and I can JTAG my router to fix it. Really appreciate!!!

The router was stuck in boot loop. I managed to connect thru serial cable, and run "nvram erase" and tried flash different firmwares thru tftp. Could not fix it.

The router has 4 different flashes, I tried flash each of them, but could not fix the boot loop. Eventually I accidentally flashed "flash0", overwrote the cfe partition, the router became total brick. There is no display on serial window. And router stuck with a solid white LED light.

Things I tried before brick the routers:
nvram erase && reboot
nvram erase && nvram erase && nvram erase && reboot

flash -noheader 192.168.0.2:firm.bin flash0.trx
nvram erase && reboot

flash -noheader 192.168.0.2:firm.bin flash1.trx
nvram erase && reboot

flash -noheader 192.168.0.2:firm.bin nflash0.trx
nvram erase && reboot

flash -noheader 192.168.0.2:firm.bin nflash1.trx
nvram erase && reboot

And finally this below command bricked the router:
flash -noheader 192.168.0.2:115-firm.bin flash0

If you happen to have a DIR-895L router runs DD-WRT firmware, please kindly made a backup of the cfe.bin bootloader file and share with me. The cfe.bin can be backup thru the web gui: http://{router IP address}/backup/cfe.bin

Thanks a million!!!!

Hi,

Please help me how I can backup CFE.BIN?
I can share a copy if I can backup.

You seem to have some experience in the subject. May be you could also help with the below:

I have one D-Link DIR-895L A2 model.
I have a different problem.
I previously had the v1.13b stock FW. I successfully flashed the factory-to-ddwrt.bin and the to dir895-webflash-bin of v3.0 Build 40559.

Everything seemed to be working fine for about 5-6 hrs. Router rebooted due to some config changes while enabling more functionality and from this point router wont boot DD-WRT firmware. Installing stock FW from the Recovery Boot menu works fine.

Uploading the DD-WRT FW either from stock FW GUI or from Recovery Boot menu shows upload successful but wont boot into DD-WRT and reverts back to Recovery Boot.

I am able to upgrade and also revert to older versions of the stock FW, with no hassles at all.

I am now stuck with the stock FW only and NO way to load the DD-WRT FW.

Please let me know if there is any way to successfully boot DD-WRT on D-Link DIR-895L A2.

Thank you very much,

Sorry I didn't read you post in detail when I replied on my phone.

For D-LINK DIR-895L, if you are on firmware 1.13, I believe you need to first upgrade to their Intermediary/Transitional firmware (1.15) before you can upgrade to any later version of firmwares like 1.20 or 1.25.

DD-WRT build 40559 is very new, likely it's using kernel of from D-LINK 1.25, I assume you have to upgrade your router to 1.15 first. Before you can install the latest DD-WRT firmware from D-LINK's emergency recovery GUI.

Hope this work for you.

Thanks again for willing to take the effort to share your cfe.bin backup.

Thanks a million,

Google would've saved you both a ton of headache.

No, what I meant was, had you googled the correct firmware, you wouldn't have bricked. I can't seem to find a bootloader anywhere for that one. Shocked

Not sure if either of these apply, I am looking up information on un-bricking on the fly here.

Thanks for the information.

I actually did try every single version of firmware I could find before I broke the cfe boot loader. Official firmware from version 1.02 all the way to 1.25. And DD-WRT build 36247 to 40559 both factory-to-ddwrt and webflash. With official firmware, it always was complains "Invalid Boot Block on disk" and then repeats rebooting. With DD-WRT firmware, it will just stuck on loading with an orange LED.

Also tried to do "nvram erase" with every firmware I flashed, but didn't help. After many different attempts flashing different flash partitions, I was less careful and end up hard-bricking the router Smile

I will still try to fix the router if I can get a copy of cfe.bin backup (I WAS STUPID NOT TO DO IT WHEN I HAD CHANCE). Now I have bought another 2 ASUS routers, fixing the DIR-895L is more for fun and experiment purpose.

well, as last chance, you can load cfe from RT-AC3200 with hardware compatible with dlink 895L. since cfe was mess, you may need opening router. According to pcb board there is 25l256=256mb=32MB. if you take off, there may be 8 pin leading internal SOIC. good luck.

DIR-895L is NOT compatible with any AC3200. It's not the same hardware at all. The 895L is closer to (but not the same as) RT-AC5300.

Almost identical, except maybe for the flash chip capacities. I usually ignore deslatha because I can't understand his bad english, anyway. If WikiDevi is correct:

https://wikidevi.com/wiki/D-Link_DIR-895L_rev_A1

https://wikidevi.com/wiki/ASUS_RT-AC3200

https://wikidevi.com/wiki/ASUS_RT-AC5300

https://wikidevi.com/wiki/Netgear_R8500

https://wikidevi.com/wiki/D-Link_DIR-885L_rev_A1 <-- closest match

Sorry to revive an old topic but were you ever able to find a copy of the cfe.bin file for the router you originally posted? I am in need of one as well. Thank you.

If serial access is possible, and it just hangs somewhere during boot, I don't think a replacement bootloader is needed unless you erased it... looking back at this thread.

https://wiki.dd-wrt.com/wiki/index.php/Serial_Recovery

If you can't get emergency room to work, there are workarounds. Apparently, D-Link requires an antique version of IE for it to work right.

I'm trying to find information about the serial connection on the dir-895l router but can't seem to find any. Do you know if they are available on the MB? Based on the OP I would assume yes, right?

I can't find anything, either. Would have been great if the OP or deslatha would've posted the pinout info, and if the serial header is populated or not. Not difficult to figure out which pin is which with a multimeter, though.
