I just purchased my FixHub Soldering Toolkit today and decided to upgrade to the latest firmware. It came with 1.0.3 and after upgrading to 1.0.7 it no longer detected the soldering iron. I decided to downgrade back to 1.0.3, but this errored during the 'resetting device' stage after it uploaded the firmware.

The display no longer shows anything at all and the device seems to not power on. I opened it and disconnected the battery for 10 minutes then reconnected it and tried to power it on with no luck.

I can put the device into DFU mode by holding down the silver knob while connecting a USB cable to the back port. It will load up in the web console, but it still shows 1.0.7 on the device and no downgrades succeed nor will the device power on.

Please help!

The error message stated: "Make sure you do not already have another connection open and try again."

I tried the following troubleshooting steps without success:

• Fresh boot with no other applications or browser tabs open.
• Tried multiple USB ports.

The solution that worked for me was adding my user account to the dialout group. I used the command: sudo usermod -a -G dialout <username> (replacing <username> with my actual username). After running this command and then logging out and back in, I verified I was added to the group using groups <username> and was then able to connect to the web console successfully after a reboot.

This seems to be a common permission issue on Linux systems for accessing serial ports.

The web console is great but not always an option if you are in an offline environment. I see that there is a basic help command but it does not seem to give much detail on individual command usage.

Is there anyway to fix this?

⟐ Answered July 14, 2026 at 13:31 MST

I was then asked to update the firmware but then found out the updater was switched off due to a current firmware issue, but they have fixed that now and i was able to update the firmware. The Soldering iron does seem a little better but i still have to unplug it a few times to actaully get it to work. When i switch the hub on the iron shows as connected and the temp shows but as soon as i switch the iron on it disconnects and i have to unplug it a few times to get it to work again.

Has anyone else had this issue and found the way to fix this?

I love the design etc but i need it to just work!

Sadly contacting for support is very slow and can take a few days just to get a reply to say update firmware, or have you tried removing the tip etc, basically the first things you would check and not need to be told to check! They really need a dedicated support email

I see the other items are being sold as a standalone product but when are they expected to be in stock?

Portable Soldering Toolkit Without FixHub

Does it make more sense to buy the whole kit and resell the duplicate iron and battery?

I do have a 3D printer and may try printing a stem, but I would like a more permanent solution

My usb-c cable from the fixhub soldering iron broke does anyone know where to source it?

Thanks

Symptoms:

- While heating, the error flashes for ~1 second, the temperature display drops a few degrees, then heating resumes. This cycles repeatedly.

- Using firmware 1.5.0 on both Hub and Iron.

- Tip is a 1.5 Bevel.

Troubleshooting already performed:

- Verified tip is fully seated (clicked in, aligned below the surface).

- Cleaned 3.5mm contacts and internal handle springs with IPA.

- Disassembled the iron handle; internal soldering points for the socket are secure and show no signs of failure.

- Measured tip resistance at ~3 ohms at room temperature.

- Tested both front USB-C ports with the original cable (same result).

- Tested with third-party 100W cables (MacBook/IKEA), which resulted in Error #11 (No Data), confirming the hub requires the specific data lines of the original cable.

The intermittent nature suggests a thermal expansion break inside the tip's sensor circuit. Are there any known issues with this behavior or specific tests I can run to verify if it's the tip vs. the iron handle's internal logic?

However the display is still not functioning. Any help/tips appreciated.

I have already tried the following troubleshooting steps:

- Disabled both Idle and Sleep timers.

- Verified the physical switch is in the "On" (orange) position.

- Cleared the error log and performed a factory reset via the FixHub Web Console.

- Ensured firmware is up to date for both the iron and the power station.

- Tried multiple power sources, including the FixHub Power Station and a high-wattage USB-C PD plug.

- Reseated the soldering tip multiple times.

Despite these steps, the heater shuts off the moment it hits the set temperature. Is this a known firmware bug or a hardware failure in the main board or tip sensor?

This is not due to my chargers or cables as I have tried a variety of adapter cable combinations that all work with my other 65W+ USB C devices (laptops, etc.)

All of these chargers only delivered 10W when they support higher wattages on other devices:

Dell 65W (supports 20V 3.25A) --> only 10W

Chromebook 60W (supports 20V 3A) --> only 10W

ASUS ROG ALLY 65W (supports 20V 3.25A) --> only 10W

RavPower 61W PD charger with 100W cable (supports 20V 3A) --> only 10W

Interestingly:

30W Anker PowerPort Atom III Slim with 100W USB C cable was able to deliver 27W at 20V.

Insignia Nintendo Switch power adapter which only goes up to 15V was able to deliver 32W at 15V.

UGREEN Nexode mini 30W delivered 27W at 20V.

This is a strange pattern. The lower wattage adapters are able to charge at their max,

but my higher wattage chargers are being limited to about 10W.

I tested these while the battery was at about 25%

I have already updated to firmware 1.5.0

Is there some form of release for the tip? I saw a guy on line just pull it straight out. Mine doesn't do that. It doesn't rotate around or move in any way.

⟐ Commented May 04, 2026 at 5:06 MST

I recently updated the Soldering station and Smart soldering iron to 1.4.3, and went about with soldering no issue.

After a little while, i got an error on the screen of the station, asking me to update to the latest firmware.

When i plugged it into a Computer and opened the ifixit console online, it tells me that the update is not complete. When attempting to finish the update, it will install no problem, but then continue to tell me the update still isn't fully installed, and wont let me continue to solder.

Downgrading to a later update, such as 1.3.x, will remove the onscreen error, but wont connect to the soldering iron. Even when downgrading the tip, the error still persists.

Going as far as downgrading both devices to Version 1.x.x, it will still say that the update is incomplete.

After disassembling the device for a visual inspection, there are two LED's flashing on the inside. D4 seems to flash almost constantly, but with D6 flashing when trying to perform any sort of update alongside D4.

Currently stuck as i have soldering jobs to finish but a soldering station that doesn't work.

Any advice or a fix would be great.

Thanks in advance.

I have already tried:

1. Performing a force shutdown (holding the Action Button for 10 seconds).

2. Attempting to update multiple times via the Web Console.

The error persists every time I power the device back on. Does anyone have any ideas?

I submitted a PR here: https://github.com/iFixit/FixHub/pull/12

Is there a better place to contribute in this way or to propose something like this?
