Recover from bad Firmware update?

Anyway to unbrick a Brother laser HL2270DW black and white printer?

All I know so far is from an email I got from a friend:

I was trying to update the firmware so I could get the Ariel font. The process got to about 90% and it stopped. It actually shut the computer down. When I turn it off, wait a bit, turn it back on, the lights stay on for about ten seconds and then it goes out again and shuts down.

Is there anything I can do, short of tossing the printer on the scrapheap?


Already tried a Reset using the GO button (8 presses) from the Brother site.
Also unplug/plug holding Power button.
Unplug/plug holding the GO button.

Any other bright ideas out there?

If you cannot do a hard reset (because the reset fails), then the BIOS/Firmware chip has been damaged.

Sometime you can re-apply the old firmware, but if you cannot get the printer going to do this, then you would have to get the printer repaired (new chip). This is probably not worth it, so I suggest a new printer.

If it has a removable CMOS type chip you can get one from a working model (provided you have another) and fudge the start.

Swap the bad one for a good one.

You may be able to start the printer and remove the good one again carefully, insert the dud one and start the fw upgrade.

Provided that nothing shorts out and you keep the process alive without freezing and damaging the good one it is a viable option.

I used to do this in the olden days when MB CMOS chips froze during upgrades.

Just an idea.

That's what he is wanting to avoid.   : D


Forgot about the old "hot swap" trick. Have to look into that.

He got this printer on sale, so he is going to let it sit for now. A family member has the same printer, so he might look into the hot swap thing at a later date.

Thanks for playing.  : )
