Add killswitch removal code and comprehensive documentation

Browse Source 
Killswitch Bypass:
- Modified getLatestAppVersionCheckResult() in EnvironmentDataContainer.smali
- Method now always returns 0 (APP_VERSION_OK) regardless of server response
- Bypasses EA's March 2026 shutdown mechanism
- Game will continue working even after EA servers go offline

Technical Details:
- Replaced 88 lines of server-check logic with hardcoded return value
- Added debug log: '🔓 Killswitch bypassed - returning APP_VERSION_OK'
- Server can send appUpgrade=2 but game ignores it
- Compiled bytecode is immutable - EA cannot revert this remotely

Documentation:
- KILLSWITCH-REMOVAL-GUIDE.md - Complete technical explanation
- How it works, why it works, how to verify
- Manual patching instructions for community
- FAQ addressing common concerns

Impact:
- v14 Ultimate APK remains playable indefinitely
- Community can continue racing after official shutdown
- Progress preserved locally
- No dependency on EA infrastructure

# 🔓 RR3 Killswitch Removal Guide
**Version:** 14.0.1 Ultimate Edition
**Purpose:** Bypass EA's server-controlled killswitch to keep RR3 playable after March 2026 shutdown
**Status:** ✅ Successfully bypassed in v14 Ultimate APK
---
## 🎯 What is the Killswitch?
EA added a **server-controlled killswitch** to Real Racing 3 v14 that allows them to remotely disable the game without pushing an update.
### How It Works
1. **Startup Check:** Game calls EA's Director API on every launch
```
POST https://director.ea.com/director/api/android/getDirectionByPackage
```
2. **Server Response:**
```json
{
"appUpgrade": 0 // 0=OK, 1=Update Recommended, 2=Update REQUIRED (blocks game)
}
```
3. **Game Enforcement:**
- File: `com/ea/nimble/EnvironmentDataContainer.smali`
- Method: `getLatestAppVersionCheckResult()`
- Returns: 0 (OK), 1 (Warning), or 2 (BLOCKED)
4. **Result:** When EA sets `appUpgrade=2`, game refuses to launch
---
## 💣 The Threat
When EA shuts down RR3 service in **late March 2026**:
❌ Stock APK will receive `appUpgrade=2`
❌ Game will display "Update Required" message
❌ No update will be available (service ended)
❌ Game becomes **permanently unplayable**
---
## ✅ The Community Fix
We surgically removed the killswitch by patching one single method in the EA Nimble SDK.
### Technical Details
**File:** `smali_classes2/com/ea/nimble/EnvironmentDataContainer.smali`
**Method:** `getLatestAppVersionCheckResult()` (line 648)
### Before (Original Code - 88 lines)
```smali
.method public getLatestAppVersionCheckResult()I
.locals 6
# Complex logic checking m_getDirectionResponseDictionary
# Gets "appUpgrade" value from server response
# Returns 0, 1, or 2 based on server's decision
# If server says 2 (BLOCKED), game refuses to start
# ... 80+ lines of code ...
return v0 # Could be 0, 1, or 2
.end method
```
### After (Patched Code - 20 lines)
```smali
.method public getLatestAppVersionCheckResult()I
.locals 1
# KILLSWITCH DISABLED BY COMMUNITY MOD
# Original code checked server's "appUpgrade" field (0=OK, 1=Recommended, 2=Required)
# This patch always returns 0 (APP_VERSION_OK) to bypass EA's March shutdown
# Game will continue working even after EA servers go offline
.line 180
invoke-static {p0}, Lcom/ea/nimble/Log$Helper;->LOGPUBLICFUNC(Ljava/lang/Object;)V
const-string v0, "RealRacing3"
const-string v1, "🔓 Killswitch bypassed - returning APP_VERSION_OK (community mod)"
invoke-static {v0, v1}, Landroid/util/Log;->i(Ljava/lang/String;Ljava/lang/String;)I
const/4 v0, 0x0 # Always return 0 (APP_VERSION_OK)
return v0
.end method
```
### What Changed?
1. ✅ Removed all 80+ lines of server response checking
2. ✅ Hardcoded return value to `0` (APP_VERSION_OK)
3. ✅ Added debug log message for verification
4. ✅ Method now **ignores** server's killswitch command
---
## 🔬 Why This Works
### Compiled Code is Immutable
- Smali bytecode → DEX → Machine code = **PERMANENT**
- EA can only change DATA (server responses)
- EA **CANNOT** change compiled METHOD CODE
- Our patch modifies the METHOD itself (not data)
- Even if server sends `appUpgrade=2`, our code ignores it
### No Hot-Patching in RR3
Investigated potential remote code injection:
- ❌ No `DexClassLoader` in EA Nimble code
- ❌ No dynamic method replacement
- ❌ No code download mechanisms
- ✅ Firebase Remote Config = **data only**, not code
- ✅ Director API = **configuration only**, not code
**Verdict:** EA physically **cannot** revert our patch remotely
---
## 📊 Testing Verification
### How to Verify Patch Works
1. **Check Logcat:** Look for this message on startup:
```
I/RealRacing3: 🔓 Killswitch bypassed - returning APP_VERSION_OK (community mod)
```
2. **Test Airplane Mode:**
- Enable airplane mode
- Launch game
- Should start normally (no network check)
3. **Simulate EA Shutdown:**
- Block `director.ea.com` in hosts file
- Game still launches (ignores server check)
---
## 🛠️ How to Apply This Patch
### Option 1: Use Pre-Built APK (Recommended)
Download **RR3-v14.0.1-Ultimate-SIGNED.apk** from releases
### Option 2: Manual Patching
1. **Decompile APK:**
```bash
apktool d RealRacing3-v14.0.1.apk -o rr3-workspace
```
2. **Replace Method:**
- Open: `rr3-workspace/smali_classes2/com/ea/nimble/EnvironmentDataContainer.smali`
- Find: `.method public getLatestAppVersionCheckResult()I` (line 648)
- Replace entire method with patched code (see above)
3. **Rebuild APK:**
```bash
apktool b -n -o rr3-patched.apk rr3-workspace
```
4. **Sign APK:**
```bash
apksigner sign --ks your-keystore.keystore \
--ks-key-alias your-alias \
--out rr3-patched-signed.apk \
rr3-patched.apk
```
