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.
