How to Fix OTA Update Failure on the Bike Screen

Quick Answer

OTA update usually fails because of Wi-Fi connection issues.
Most problems can be solved by:

• Using 2.4GHz Wi-Fi (not 5GHz)

• Keeping the bike within 5 meters (16 ft) of the router or hotspot

• Restarting the router or resetting network

• Using a two-phone hotspot method

Symptoms

You may experience one of the following:

• OTA update stuck at 0% or 99%

• “Network error” message

• Update starts but fails repeatedly

Why This Happens

Common causes:

• Connected to 5GHz Wi-Fi (not supported)

• Weak Wi-Fi signal

• Router cache error

• Phone network conflict

• Too many devices on the same network

Step-by-Step Troubleshooting

Step 1 – Confirm Wi-Fi is 2.4GHz

1. Open your router settings

2. Make sure the network is 2.4GHz

3. Do NOT use 5GHz Wi-Fi

4. Avoid mixed “2.4G/5G auto” networks if possible

Tip: Many routers show “2.4G” in the Wi-Fi name.

Step 2 – Check Distance

• Keep the bike within 5 meters / 16 feet of:

  • Router, or

  • Mobile hotspot

• Avoid walls or large metal objects between them

Step 3 – Reset Network

Try these one by one:

1. Restart your router

2. Reconnect Wi-Fi on the bike

3. Restart the bike screen

4. Try OTA again

Step 4 – Airplane Mode Trick (Phone)

On your phone:

1. Turn ON Airplane Mode

2. Wait 10 seconds

3. Turn OFF Airplane Mode

4. Open the app and retry OTA

Step 5 – Two-Phone Hotspot Method (Most Effective)

If update still fails, please use this method:

You need two phones

 Phone A – as hotspot
 Phone B – to run the YESOUL app

1. On Phone A

   • Turn on personal hotspot

   • Keep it near the bike

   • Important: Make sure the hotspot is set to 2.4GHz. If using an iPhone, enable Maximum Compatibility.

2. On Phone B

   • Connect to Phone A hotspot

   • Open YESOUL app

   • Start OTA update

3. When the screen asks for Wi-Fi

   • Select Phone A hotspot

   • Enter hotspot password

   • Continue OTA

     

This method solves 90% of failures.

Important Notes During OTA

• Do NOT turn off the bike

• Do NOT exit the app

• Keep screen on

• Update may take 3–8 minutes
