How to open and view a replay from Blitz.gg on Android: 5 working methods

Replays from Blitz.gg are recorded matches from League of Legends, Valorant, Dota 2 and other games that allow you to analyze your own game or study the tactics of professionals. However, many users encounter a problem: the downloaded replay file (usually with the extension .rofl, .lrf or .dem) does not open on an Android smartphone. Unlike a PC, where there is an official client for this Riot Games or Valve, on mobile devices the process requires additional steps.

In this article we will examine all current methods viewing replays on Android - from using specialized applications to converting files into universal formats. You will also learn why some replays may not play and how to work around common errors. If you play LoL, CS2 or Dota 2 and want to analyze matches directly from your phone, this guide is for you.

⚠️ Attention: Not all replays can be opened on Android directly. Files from League of Legends (.rofl) require conversion, and replays CS2 (.dem) require a special player. Details below.

1. What replay formats are there and how to open them

Before trying to open the file, determine its type. The choice of viewing method depends on this:

🎮 League of Legends (.rofl) — recording a match from the client Riot Games. On Android it opens only after conversion to .mp4 or through an emulator.
🔫 Valorant (.lrf) - similar to LoL, requires conversion.
🎯 Dota 2 (.dem) - demo file, played in the player Dota 2 Replay Viewer (there are unofficial ports for Android).
🖥️ CS2 (.dem) — demo from Counter-Strike 2. To view you need a player HLTV or conversion.
📁 General formats (.mp4, .avi) — if the replay has already been converted, any video player will open it (for example, VLC or MX Player).

🔹 How to find the format? Look at the file extension in the manager (for example match123.rofl). If the extension is hidden, enable its display in the file manager settings (in Total Commander or FX File Explorer this is done in one click).

⚠️ Attention: Replays from Blitz.gg downloaded in the original game format. If you downloaded the file through a browser on your phone, it will not open “as is” - additional steps will be required.

2. Method 1: Converting replays to video (for LoL, Valorant, CS2)

The most reliable way to watch replays on Android is to convert them to a universal video format (.mp4 or .mkvFor this you will need a PC (Windows/Mac) or. online service.

Step-by-step guide:

Download the replay to your computer (if it is already on your phone, transfer it via Bluetooth, cable or cloud).
Install the official game client:
- For LoL — League of Legends Client.
- For CS2 — Steam with installed game.
- For Valorant — client Riot Games.

Open the replay through the client and record it using built-in tools or third-party apps (for example, OBS Studio).

Save the video to disk and transfer it to your phone.

🔹 Alternative: If you don’t have a PC, try online services like Replay.gg (for LoL). Upload the replay there, and the system will generate a link to the video, which can be opened in the phone's browser.

Computer with the game installed

Screen recording app (OBS, Fraps)

Free disk space (1-2 GB for video)

-->

⚠️ Attention: Conversion via OBS can take a lot time (up to 30 minutes for an hour of gameplay). To speed up, reduce the recording resolution to 1280×720 and bitrate to 3000 Kbps.

3. Method 2: Viewing through the Windows emulator on Android

If the conversion is not suitable, you can run the original game client directly on your phone using a Windows emulator. This method works for LoL, Dota 2 i CS2, but requires a powerful device (from 6 GB of RAM and a processor level Snapdragon 855).

How to set up:

Install the emulator Wine or ExaGear (paid, but more stable). Alternative - Termux s wine (for advanced users).
Download the game client (for example League of Legends) and install it in the emulator.
Place the replay file in a virtual folder C:\Riot Games\League of Legends\Replays (for LoL).
Start the client and open the replay through the menu Profile → Replays.

🔹 Problems and solutions:

🐢 Lags: Reduce the emulator resolution to 800×600 and disable vertical sync.
❌ Startup error: Check what's in the emulator installed DirectX and .NET Framework (downloaded separately).
📱 Not enough memory: Close all background applications and use "performance mode" in the phone settings.

List of compatible emulators for Android

Wine for Android (free, but difficult to configure).
ExaGear Strategies (paid, optimized for games).
Qemu (for advanced users, requires manual configuration).
Bochs (slow, but supports old games).

⚠️ Attention: Windows emulation on Android is a resource-intensive process. On weak smartphones (<4 GB of RAM), the replay will be played with severe slowdown or will not start at all.

4. Method 3: Specialized applications for replays

For some games, there are mobile applications that can open replays directly. Their functionality is limited, but they do not require a PC or an emulator.

Game	Application	Format	Link (Play Market)
League of Legends	LoL Replay	`.rofl` (partially)	Not in the official store
Dota 2	Dota 2 Replay Viewer	`.dem`	Download APK (unofficial port)
CS2	HLTV Mobile	`.dem`	Not in the official store
Valorant	No applications	`.lrf`	—

🔹 How to use:

Download the APK file of the application (for example, Dota 2 Replay Viewer c 4PDA or XDA Developers).
Allow installation from unknown sources in Android settings (Settings → Security → Unknown sources).
Place the replay file in folder Download/Replays (or the one specified in the application settings).
Open the application and select the file to view.

Important: Applications for replays are often not updated and may not support the latest versions of games. For example, Dota 2 Replay Viewer does not work with replays after. updates The International 2023.

💡

Before installing the APK, check the file hash (MD5) on the developer’s website - this will protect against viruses. Use the application Hash Droid to check.

5. Method 4: Cloud services for viewing replays

If you don’t want to mess around with conversion or emulators, use online players. They allow you to upload the replay to the server, which will convert it into a video and provide a link for viewing in the browser.

Popular services:

🌐 Replay.gg - for League of LegendsUpload .rofl, you get the video from. timeline analytics.

🌐 Demos.tf — for CS2 and TF2. Shows player statistics and shot trajectories.

🌐 Dotabuff Replays — for Dota 2. Integrated with the statistics service. Dotabuff.

🔹 Instructions:

Register on the service (usually you need to link your game account).

Upload the replay file via the web interface.

Wait for processing (from 2 to 10 minutes).

Open the generated link in your phone browser (Chrome or Firefox).

⚠️ Attention: Some services (for example, Replay.gg) require confirmation of ownership of the account from which the replay was recorded. If you downloaded someone else's match, you will not be able to play it.
💡
Cloud services are the easiest way to watch replays on Android, but they depend on the stability of the Internet connection and may limit the number of downloads per day.

6. Method 5: Manually extracting video from replay (for advanced)

If you are familiar with the command line, you can extract video from replay without full conversion. This method is suitable for CS2 and Dota 2.
Tools:

🖥️ FFmpeg (install via Termux on Android).

📂 HLTV (for CS2).

📂 Dota 2 Console (for Dota 2).

Example for CS2:
# Install Termux and run: pkg install ffmpeg Download the replay to the ~/downloads folder Extract the video (it will take ~5 minutes per match):
ffmpeg -i match.dem -c:v libx264 -preset fast -crf 22 -c:a aac -b:a 192k output.mp4

🔹 For Dota 2:

Download Dota 2 Replay Parser (Python script) to PC.

Run with the command:
python parser.py -i replay.dem -o video.mp4

Transfer video.mp4 to your phone.

⚠️ Attention: This method requires knowledge of working with the terminal. Errors in commands can lead to the loss of the replay file. We recommend that you first practice on a copy.
7. Typical errors and how to fix them

If the replay does not open, check these. points:

🔴 "The file is damaged" —download the replay again. If the problem persists, check the checksum (MD5) of the file.

🔴 "Not enough memory" —free up space on your phone or use a cloud service (Method 4).

🔴 "Playback error in the player" —try VLC or MX Player with the decoder turned on SW.

🔹 Frequently asked questions:

📌 "Can I open the replay without a PC?" — Yes, but only for Dota 2 (via unofficial APK) or through cloud services.

📌 "Why is the video slow?" — Lower the resolution when converting or use a player with hardware acceleration (VLC).

📌 "The replay opens, but without sound" — When converting, add the flag -c:a copy to FFmpeg.

How to check the checksum of a file on Android

Install Hash Droid from Play Market.
