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?

So, I figured the battery must be dead. However, when the device is plugged into power it shows that the battery is full and my charger shows no power draw. It does not display an error message while plugged into a charger.

I found the support article indicating this may be a firmware issue with available hotfix. I plugged into my PC and immediately received the error "Battery Error, Tool Shutdown" I didn't see this one listed in the error code list, which is strange.

I was able to hold down the wheel while plugging in, and was able to update firmware successfully to 1.5.0. No change. Unable to start device; receive error when plugged into a PC. I also successfully updated to 1.3.2 after seeing another forum post regarding the boot loop issues in 1.4.0, but no dice. I've also tried 1.4.1 after seeing there was a hotfix for that issue.

After updating to 1.3.2, it did flash a different error for a moment, but changed back to "Battery Error - Tool Shutdown" before I could read it. I've since updated the firmware back to 1.5.0.

The FixHub updater recognizes the device when it's plugged into my PC and shows 100% charge (sometimes starts at 107% or 51% before correcting to 100%) and accurately reflects the current firmware version in the webapp.

The only other information I can give that's interesting - when updating firmware it will reset, show the full battery, then display the error message on screen while the firmware is still updating.

Got any ideas for a fix? I'd love to use this thing!

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 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’ve confirmed that both the Smart Station and the Iron are running firmware version 1.4.0. However, when I downgrade both devices to version 1.3.2, the error disappears.

I believe this may be a false error. When I check the firmware directly from the Smart Station’s menu, it correctly reports that both the Smart Station and the Iron are on version 1.4.0.

However, when I click on the error message in the Fix It Hub Console, it shows the Iron firmware as blank, while the Hub firmware still shows 1.4.0.

I’ve also tested this on a second computer to rule out a browser issue, and the behavior is the same.

Any thoughts on what might be causing this?

I bought the FixHub soldering station kit sometime in February-March 2025, when the FixHub was still marked for pre-order (I think?), but was already on the shelves of Micro Center. I had only tried to turn it on for the first time after purchase yesterday (which in hindsight was an extreme misjudgement for quality checks of purchased tools that are relatively valuable). So, naturally I figured the battery probably drained out during that time.

I saw mentions of updating the FixHub's firmware via web searching, but I wasn't able to figure out how to do so until today. I was able to use the FixHub's web console page to update the FixHub to the latest version of 1.4.0. So, at least the FixHub wasn't dead on arrival.

However, 1.4.0 firmware version ends up in a very bad edge/corner case when the device is drained to 0%, has its firmware immediately updated to 1.4.0, and then attempts to charge its completely drained internal battery.

Generally FixHub will attempt to charge and the charging animation will come up, but eventually within 10-15 seconds encounter battery error B02/battery disconnected (though only once I saw it experience battery error B04/battery charging stopped for protection in the error logs part of the settings). (The FixHub error codes can be looked up here.) The FixHub will then turn itself off, and the empty battery icon will show when FixHub is turned off. If one attempts to turn of FixHub in this state, then the normal on menu will come up, but the battery icon will flash between completely empty (with just the battery outline) and the slightest line charge to show the 0% battery state. Due to this state, one can only get FixHub to navigate through the settings menu, but won't be able to heat up to solder. Not even using a non-PD cable of USB-A and USB-C could get the FixHub to begin charging past 0%.

I was able to resolve this issue by downgrading the firmware (or conducting a firmware downgrade attack, if the FixHub were to be used in a more stringent infosec scenario; but also not really because there was no firmware rollback protection in the first place) to the second latest firmware version 1.32, as I found the FixHub web console was still always able to work with the web serial interface. (Coincidentally, this reminds me of the web installer for Google Pixel/GrapheneOS, as these also seem to only work with Chromium-based browsers.) The process may have failed once at most, though I was able to simply refresh the FixHub web console page to start the process over again very quickly. Once I successfully flashed firmware version 1.3.2, then FixHub was able to charge with a "typical" GaN charger from 0% with no boot looping.

Although this is likely a rare edge case "in the field", if this issue can be reproduced, then I would recommend that this boot looping issue should be fixed in the next FixHub firmware release.

Update: I was able to upgrade the firmware from version 1.3.2 to 1.4.0 after the FixHub was fully charged. (I made sure to reset the battery health via the web console.) Before I upgraded the firmware and probably when the battery became fully charged (I wasn't home while it charged), the FixHub experienced a total of at least 4 consecutive B16 battery errors/battery warm (not hot). (The FixHub can only save a max of the latest 4 errors in the error log.) After about 2-3 failed attempts of upgrading the firmware from 1.3.2 to 1.4.0 (including when there was a false success result and the firmware stayed at 1.3.2), the FixHub was able to update to firmware 1.4.0. I will test to make sure the soldering functions work on the FixHub, to make sure the FixHub functions properly. If I don't make any further edits, then assume that the FixHub is working fine.

Final update: This issue seems to have been addressed in firmware version 1.4.2. According to the release notes for this version on August 8, 2025, the changelog on the console page states:

• Fixed bootlooping errors that occurred when charging a dead battery
• Improved accuracy of charge timer warnings
• Minimized interruptions and clarified language regarding battery temperature errors

Replacement battery packs were sold out here so i bought a DIY spot welder and six Molicel batteries. I replaced the cells and tabbed it the same way i saw it when i disassembled. I can read 4V from pos-to-neg on each cell. they all have the same chemistry (i drain/charge checked them).

I get 2.0V across the terminals/connector but I can't get the power station to come up.

I was able to hard reset the station and upload the latest firmware (1.4.3 at this time, i believe).

Is the BMS on the battery dead? is the pack not serviceable?

I would've just bought a replacement pack and called it a day but I'd like to try and salvage something from my attempt here.

Any info would be appreciated. Thanks.

I just updated the firmware and reset settings on the web console.

I'm using the provided USB-c cable.

What am I doing wrong? Why doesn't the manual have the error codes for the LED indicator light in a troubleshooting section?
