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
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,

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
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:
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.
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?
