If you still have a computer that hasn't been rebooted since it failed (guessing not) then you could get the MAC from `arp -a`...otherwise I guess you could take it apart and see if there's a MAC label inside.
If you're flashing the chip, you could try to read that block first, open in a hex editor, and see if the MAC is still available. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#

thanks. inside is no label with mac. and the chip was flashed with a custom firmware. and there is a generic mac now.
based on serial number. i will send an email to xiaomi

Xiaomi R1D xVortex CFE FullDump Tomato NVRAM
As I've searched all over the internet for a full dump for this router to unbrick my unit I've decided to post a clean version for anyone to use if needed.
It's from my own router, but with a generic MAC.
If you want to use your own MAC, use the xVortex CFE editor to create a new CFE and just overwrite the first 256 KB of the file.
The structure I've used in creating the file is
256KB - CFE
16000 KB - SYS file
128KB - NVRAM
In Tomato, bricking the unit is caused when FULLY erasing NVRAM, bringing the values to defaults is no problem.
With the included xVortex CFE you will have access to the CFE by powering the unit while holding reset for 10 seconds. Only downside I've found is the power/connection LEDs don't work anymore.
A lot of sweat and blood was shed in unbricking/creating this dump from scratch (mostly understanding why it doesn't boot with only the CFE flashed and making the damn CH341A flasher work with Win 10 - use v1.18 ).
2021 edit: After flashing reset NVRAM by holding reset button for 10 seconds to make sure the required NVRAM values are present.
reset_gpio=17 (Reset Button is active)
wait_time=12 (Access CFE server time)
uart_en=1 (console is always active)
model=R1D (Router model)
How to use this Clean Dump?
I have bricked my xiaomi r1d , i cleared NVRam on Fresh Tomato now only orange light and lights on back blink, lan connects and disconnects, what to do?
Restore with miwifi.bin doesnt work, orange light not blinking
I broke my R1D by clearing the NVRAM on Tomato and I am now trying to flash with the CH341A but I can't get the chip to read (even less write) to the router.
I have connected TXD, RXD and GND to the J252 socket but then unsure what to do next.
Is there any place online that explains how to interact with a J252 socket? Or how to flash the NVRAM to the router?
From what I remember, I think you need to actually desolder the chip, I don't remember why I desoldered it, but it didn't worked if I tried to leave the chip in circuit. There are also some resistors around the chip that can interfere with a clip.
Anyways, to desolder it easily with a small tip soldering iron, just tin together the pins on both sides, and slowly, while inserting the tip of a surgical needle below the chip work on both sides alternatiovely, SLOWLY lifting the chip, never applying too much force.
You'll lift it in under 2 minutes, you just need to have patience, as forcing the chip to lift can lift the pads probably (I used this method to lift al kinds of SMD chips and it works because the metal pins have a certain give to them).
Never lifted any pads, but well I know my way around a soldering iron.
I revisited the thread as, well, even with Vortex CFE installed I managed to brick it again.
Words of wisdom: always use the CFE to flash and reset NVRAM to defaults. Seems to be the only method which actually never failed when you need to fully reset the router. Bricks are caused by selecting Clean NVRAM Throughly when updating firmware (TOMATO).
Dirty flashing and resetting NVRAM to defaults always seemed to work.
NOTE: Black CH341A users shoul apply the 3.3V fix as explained on this page (last paragraph).
I would like to update My Xiaomi R1D Router, but I was unable to set the new IP on the router. It seems that everyone understands the procedure well and I am a bit stupid.
I perform the procedures below successfully.
nvram set boot_wait = on
nvram set wait_time = 10
nvram commit
Is there a command to change the router's IP?
I already have the developer stock ROM. After the IP change, does the CFE panel appear to upload the new firmware?
