Moza iFocus - Anyone Else Have This Issue?

Got the Moza Air 2 and an offset plate to work with my Pocket 4K and was starting to get some pretty good test results with the Pocket 4K on there (much better than what I got with the C100mkII on the gimbal) -- but all of a sudden the iFocus motor has totally frozen. The LED is a solid green light (which in the manual doesn't seem to be any correct mode), and it won't respond to the power button or the Moza Air 2 when connected to the Multi-CAN port.

Their support is as bad as everyone says, can't get a response on any channel. Has anyone else here had this issue with the iFocus? Any idea on how to do a hard reset? Was hoping to use this setup on a shoot tomorrow - so much for that!

Thanks for any help anyone can give or point me towards!

If anyone else ends up having this problem, it's an error of a failed firmware upgrade. Let the iFocus run out of power, then recharge and connect to the Moza while turned off. Connect Moza to a computer in upgrade mode with the Moza Master app open, then long press the iFocus power until the white light comes on to enter upgrade mode. Update the firmware and turn off both iFocus and Moza Air 2 and -- for me at least -- the iFocus will work again!

Thanks for posting this info. I'm having the same issue. I tried to upgrade the iFocus firmware via the Moza iOS app, but it's causing the same crash each time. And for whatever reason my Mac/Moza_Master app isn't recognizing the Air 2.

Has your iFocus continued to work after the steps you described? I'm tearing my hair out here. Currently won't power down (again)-- it's just frozen on a green light.


Thanks,
Jules

Hi Jules,

No, it's been working fine since I did the firmware install. Moza Master can't find the gimbal even when it's turned on normally, or only in firmware update mode?

Yeah, the battery on the iFocus is a beast. Great for shooting - not so great for failed firmware update freezes. Did you reach out to Gudsen? They did reply after a few days, I had just already figured it out by the time they got in touch so maybe they can help you too -- but of course I'm happy to help as well if I can!

I have been mind boggling all day over this issue. Will try this as soon as it's out of power. Thank you.

UPDATE: I can confirm this solved the issue for me too.

And for whatever reason my Mac/Moza_Master app isn't recognizing the Air 2.

I noticed the app does not recognise the Air2 when using a USB-C to USB-C cable, but it did find the device when I used the USB-C to USB (A-Male) cable which shipped with the Air2 (through an adapter as I'm using mac with USB-C only). Furthermore, I installed the driver that was in the download archive before launching the software.

Arild--

I had the same issue WRT Moza_Master on Mojave. I uninstalled/re-downloaded/re-installed the driver and then the app recognized the Air 2. This time the iFocus updated firmware successfully.

I think there might have been an issue when updating firmware via the iOS app (which I tried multiple times).

Everything is working now after re-installing the driver on Mac OS and performing the firmware upgrade that way.

With a USB-C to USB-C cable?

I used usb-c to usb-A and put it into a hub that is USB 2.0. I read someplace that the Moss doesn’t do well via usb 3.

Thankfully this thread exists or I would have just returned my ifocus unit. Anyway, I'm still having problems. It's currently stuck on green again, after letting it run out of battery and recharging it. Is it because I tried to power it up normally? Is there something I'm missing?

Yes, that's right. You can't just power it up normally, you'll need to re-install the newest firmware. So let it die, connect it to the Moza, connect the Moza to your computer (won't work with the mobile app) and then hold the iFocus power button until the LED turns white (for pair mode). Let us know if this works for you!

Yep, worked perfectly. Thank you again for your help.

I would really like to update the driver now and would not like to wait until it dies, so I wanted to confirm that there was a way to do this? It appears most here have waited until the iFocus has died before trying to update the driver.

If I have to wait until the iFocus does die, I just want to confirm that I am updating it correctly for later.

Are these steps correct?
-iFocus dies
-Connect iFocus via USB-C to micro usb Moza Air 2
-Connect Moza air 2 to Windows (preferably)
-Turn on Moza air 2 into boot mode
-Turn on iFocus until it turns white
-Update firmware?

Thanks in advance

I have the same issue with the ifocus and the frozen green light. Only trouble is the MOZA master desktop app on my iMac is not recognising the air 2 at all so I have no way of reinstalling the firmware.

I have reinstalled the software and silicon labs VCP driver 4 or 5 times, and have also tried a number of USB C cables, but nothing seems to work.

Needless to say the Gudsen customer service is not happening.

Can anyone advise me??

Hello everyone.

I have the same issue with my iFocus, I bricked it to solid green light.
At least I am glad you provided a solution.

I have a two questions:
- How long before the battery dies?
- Can I pair my iFocus Motor with my iPhone and control focus over iPhone App?

Thank you very much!!

tried a number of USB C cables

Did you use USB-C to USB-A? That's the only cable that worked for me to recognise the device (running through an adapter to the MacBookPro which only has USB-C). A direct USB-C to USB-C did not work for me.

I used usb-c to usb-A and put it into a hub that is USB 2.0. I read someplace that the Moss doesn’t do well via usb 3.

-Connect iFocus via USB-C to micro usb Moza Air 2

That step is wrong. Use the normal connection via Multi-CAN. The USB-C port on the iFocus is only for charging, I believe.

I have a similar issue but it’s with the iFocus M. Solid blue light, and no focus icon on the moza.

Hello everybody. I have a slightly different problem. My iFocus motor works all right with the gimbal (latest versions of software and firmware) but the remote doesn't pair. It never did. The motor LED is solid blue even when I am not charging the unit. That LED never stays green, it jumps immediately to solid blue.

Any suggestions short of returning the unit and looking at a different brand?

Thank you.
