work force pro printer 4630: Problem downgrading the firmware of an Epson WF-7840

Wed, 10 Jun 2026 16:40:36 -0700

Good morning everyone,

I've had the bad idea to upgrade the firmware of our Epson WF-7840 (version CD17M6 now).

Now, our non epson cartridges are not recognised anymore.

I've search the web about how to downgrade the firmware. I found the procedure, found how to put the printer in "recovery mode" and, on the Epson website, I found the "Recovery Mode Firmware version CB08LC" for the Epson WF-7840.

But it doesn't work...

First problem, the model of the printer does not appear in the "Epson firmware updater" but it sees that a printer is connected.

Second problem, and it is where it stops, when I launch the Update, it fails with a message on the printer's screen "Data file not found".

I tried with my mac (macbook pro 16" m1 max) and with an older macbook pro from 2009 with the same result. I tried with another USB cable and still no luck.

What am I doing wrong?

Lenovo ThinkPad P52s: New internal battery not recognized

Wed, 10 Jun 2026 12:48:05 -0700

I just replaced the internal battery on my Lenovo P52s, but Windows 11 does not recognize the battery. I've done the following:

Removed battery devices and rebooted; they came back but battery not recognized.

Held down the reset button on the bottom of the laptop for 30 sec.

Removed external battery and power and held power button down for 30 sec to de-energize.

Any ideas?

Thanks,

Bob

Apple TV 4th Generation: Apple TV 4 (A1625) Boot Looping

Wed, 10 Jun 2026 12:12:27 -0700

My Apple TV 4 is not able to fully boot up to the home screen.

It displays the Apple logo that you'd normally see during the boot process. After the light on the front of the device blinks 9 times, it seems to immediately reboot itself.

On just one occasion since this began, iTunes was able to see the Apple TV temporarily when I had connected it with a USB-C cable (with the intent to be to do a software restore on it, if possible).

I have tried two power cables (borrowed from another working Apple TV), two HDMI cables (not perceived to be an issue since we can see the boot logo on screen), different power outlets, and even different televisions.

There are articles on holding the TV and Menu buttons on the remote for 10 seconds to force it to restart. The Apple TV does seem to react to the remove (the light on the front will flash in response to it), but this did not permit a full boot.

Thoughts on what hardware components inside of this would be worth swapping out to get this working again?
