onda Windows repair package

When to use:
Use this package if v2rayN used to work, but after a core update it starts showing
Delay -1 or this log message:
"REALITY: received real certificate".

What it does:
1. Finds v2rayN on the computer.
2. Backs up the current bin\xray\xray.exe.
3. Restores the onda-tested Xray 25.3.6.
4. Marks xray.exe as read-only to reduce the chance of another automatic overwrite.

How to use:
1. Do not run it inside the zip preview. Click "Extract all" first.
2. Open the v2rayN app you normally use first, so the repair tool can find the right folder.
3. Double-click Run-Onda-Xray-Fix.cmd.
4. If Windows blocks the script, open PowerShell in this folder and run:
   powershell -ExecutionPolicy Bypass -File .\Fix-Onda-v2rayN-Xray.ps1
5. Reopen v2rayN, select an Osaka node, then test delay again.

Important:
- Do not use core update inside v2rayN.
- The repair closes v2rayN and xray.exe during repair, so the internet may drop briefly.
- If the computer has more than one v2rayN copy, choose the one you actually use.
- If it still does not work, send support the onda-xray-fix-log-*.txt file in this folder.
