I have been very pleased with Hansshow’s hardware; I have installed their Frunk Open / Close hardware and paid somebody else to install their Auto-Present Doors hadrware on both my Driver-side and Passenger-side doors.
But, as with many Chinese firms, the instructions to operate some aspects of these after-market parts have been somewhat challenging to decypher.
The notes below are specific to iPhone as that’s what I use exclusively these days. If you’re using Android or a separate dedicated Wi-Fi router, you’re presumably tech savvy enough to translate what I’m saying below to apply to your own device.
You will need to RENAME your iPhone temporarily for this to work. For simplicity’s sake you will want to take a screen shot of the current iPhone Name and Mobile Wi-Fi hotspot password so you can set them back when you are done.
So, based on my recent experience, here is what you do to update your Hansshow Auto-Present door module firmware OTA:
- In iPhone Settings, got to General > About and tap on the Name field. Change this to SLOTA
- Next go back to the Settings main page and tap on Personal Hotspot
- Tap on Wi-Fi Password and replace the current password with 88888888 (eight 8’s) and tap Done.
- Make sure that the Maximize Compatibility slider is set to ON (see picture).
- While still on the Personal Hotspot screen, go into your Tesla and tap on the Wi-Fi icon on the top of the screen to allow you to select which Wi-Fi the car is talking to.
- SLOTA will shortly appear, choose this and enter the 88888888 password when prompted. You are doing this to ensure that the iPhone hotspot is active and *stays* active while you are messing about with the update. Be very deliberate when tapping in all those 8’s as the Tesla interface is a bit sloppy and I found it would drop one or two of them when I was typing them in. Make sure that you are using eight 8’s.
- Open the car door you want to update.
- Press and hold the Black Control Button that was included and installed as part of your Auto-Presenting Door module install. It should slowly start beeping after about 3-6 seconds. If it does NOT start beeping (as can happen with the recent issues caused by Tesla’s recent firmware update), you should still be able to press and release the Black Control Button to tell the door to close. Then, using your elbow, just stop the door from closing all the way. It will push against you for a moment, then beep in protest and back off a bit. You should now be able to press the control button to initiate the update.
- Press and hold the Black Control Button continuously, after about 3 seconds you should begin to hear a beep. Keep pressing and you will hear more beeps. Keep holding the button until you have heard 6 slow beeps.
- Release the button and you will hear 6 rapid beeps. This confirms that you held it for 6 beeps.
- You should now hear a steady beep that will last between 30-50 seconds. This is normal.
- If you hear 5 1/2 rapid beeps (the last one just trails off) then you have applied the firmware. If you don’t hear anything after the long beep, then the update has failed. In my case it did this before I turned on the iPhone Mobile Hotspot Maximize Compatibility slider and couldn’t download the needed files.
- Test the car door using the Door Unlock button to make sure it closes properly.
- Adjust the other door settings (I don’t know if they always get reset but I adjusted these with each update), here are the commands to do this. I adjusted the door opening distance and the door speed (1 Beep and 3 Beeps)
- Once your are satisfied that the update is done, or you need your mobile hotspot back to normal. Go ahead and rename your phone back to its original name and re-set your Wi-Fi mobile hotspot password by using the instructions above.
Maximize Compatibility will allow use of the older 2.4 GHz Wi-Fi bandwidth. The Hansshow modules don’t use the newer 5 GHz standard. I’ve run into this issue with several dedicated Wi-Fi devices in the past. I have to imagine it’s cheaper to use this component than one that can use multiple bandwidths.
Hi Marc.
Did the update, but as you, the left side door now controls both sides. I read someone had an updste for passenger side, can you help with this please?
Hi Stig,
It’s a long shot, but as of right now (April 8, 2025 @ 2:20 AM Eastern Daylight Time) Hannshow has the English, Left Hand Drive, Passenger door file up and available to apply by OTA.
I imagine it should be available for at least a few hours (maybe until 6 or 8 AM?).

Hi Marc,
Yes, I was in contact with them in China, and asked the to change the OTA update for this side. It works perfect now. My concern is, what will happen next time? Do we need to get in contact with them again, as the update via USB did not work for my car, only OTA update worked.
Hi Stig,
100% yes, we’ll have to do this dance the next time as well.
I did suggest to them that they needed to update each of the firmware files with a unique name/location so that subsequent updates wouldn’t need so much back-and-forth but I suspect it was lost in the translation.
Honestly, they need to poke 4 holes through their firewall instead of just the one and accommodate both driver and passenger firmware for each of the Right-hand and Left-hand modules.
While it’s a pain to do from a security and approvals perspective (assuming they are that big a company), it’s technically pretty straightforward. Then they only need to deal with the headaches of the legacy folks who weren’t updated the first time around…
Agree – I’m also missing informations on this from them, plus an update on the website, so it is not needed to contact them each time. Hope they will find a solution as you suggest, this would solve alot of issues.
Marc this page and it was awesome!! Follow the instruction and bam! It works perfectly. Thanks!
hi marc, thanks for sharing. i could not post in the other forum so i’ll post it here.
My vehicle is a right hand drive. I followed your instructions to update the left door and it worked. However when i updated the driver’s door (right side), it will only open and will not close. in fact it will open it hard until it reaches its maximum opening. I think it may damage the door of this continues. so i am disabling it at the moment (beep option #4).
Has anyone had any luck on getting the OTA update to work for the right side driver door?
My left side passenger door is working normally now. However when i press the control button to open the left door, the right door will open too.
Hi Peter,

Hi! Sorry for the odd question but I decided to remove the speaker from my module because I hated how cheap the beep made the car feel lol. Can you by any chance count the seconds it takes to reach the firmware mode if you can? I’m worried I might press it for too long or not long enough since I can’t hear it 😭
Hi Ari,
Sorry for the late reply. I just did the OTA for my passenger door again at Hansshow’s behest and timed it for you.
From the time you first press the control button it takes 28 seconds for the 6th beep (the one to initiate OTA) to complete.
Then it takes another 33 seconds for the update to complete. This last is not so critical but at least gives you a minimum amount of time to wait before you try to do anything with the door.
Marc
Hello. As of April 16, they still haven’t uploaded the right hand passenger side door for the US. I’ve been trying and trying with them but they’re not even responding as of this week. Super frustrating because every time I open the driver side, the passenger side unlatches
Hey Marc,
After the last update, I lost all communication with the passenger-side Auto Present door. Did you experience the same issue? When I press the button for the right side, nothing happens—not even a single beep. Have you tried this?
Hi Stig,
No, I’m afraid I haven’t encountered this issue. I did see some references in the Tesla Motors Club forums where people were disconnecting their 16 volt battery to reset the door modules. Maybe check out their forums to see if this might apply to this issue for you?
There was also some discussion about what some folks did with “bricked” modules. In some cases I believe the vendor ended up sending out replacement modules.
Hopefully you don’t have to go to that extreme to get your door functional again.

Hi Marc, My son push the door out a bit more, and the it started to work fully again. I do not know why or how.
But thanks for your fast reply.
