Max device 20 for test

Hey everyone, As a hobbyist and part of this community, I’ve spent a significant amount of time deep-diving into the reverse engineering of the Realme 7 Pro (RMX2170) to find a local bypass for the bootloader unlock (UBL) now that the official "In-Depth Test" servers are permanently offline since two years. I am writing this breakdown to show you exactly what has been tried, why it failed, and why any future questions regarding unlocking the bootloader on this device should be strictly banned by the admins due to absolute technical impossibility. What was attempted and the brick walls encountered: 1. APK Modding & Smali Refactoring (The Userspace Route) - The Idea: Decompile the In-Depth Test APK (both v1.0.1 and v1.1.0), bypass the resultCode network check in StatusActivity.smali by forcing an unconditional goto jump to the success screen, and trigger the reboot bootloader intent locally. - The Wall: ColorOS/RealmeUI layout locks down package signatures directly in the kernel. Leaving the 'com.coloros.deeptesting' name breaks installation because your personal key doesn't match official platform certificates (INSTALL_FAILED_SHARED_USER_INCOMPATIBLE). Trying to bypass this by changing the package to example 'pl.realme.unbrick' and cutting out 'sharedUserId="android.uid.system"' fails too —the OS framework just hits the app with a quick SIGKILL right when you tap the icon. 2. Local Intent Injection via ADB - The Idea: Bypass the UI and directly trigger the unexported success activity via ADB shell (am start). - The Wall: Android blocks this approach instantly with a SecurityException (Permission Denial). The target activity has its exported flag set to false and strictly demands system-level privileges (UID 1000) to be invoked from userspace. 3. Low-Level Firmware & EDL Manipulation (The Chipset Route) - The Idea: Bypass Android userspace entirely, boot the Snapdragon 720G (SM7125) into EDL (Emergency Download Mode), dump the raw storage, and manually flip the OEM unlock configuration bits in partitions like config or frp. - The Wall: I extracted and performed a binary strings dump on the raw Qualcomm Firehose loader (.elf programmer). The output definitively confirms that Qualcomm Secure Boot is strictly enforced via an asymmetric cryptographic handshake (Firehose Authentication). The loader embeds the hardcoded public keys and certificate roots inside its code: - General OPPO 19567 Root CA1 - OPPO ROOT CA0 - OPPO Attestation CA0 The hardware BootROM inside the phone generates a random challenge that must be signed using a private key accessible only by Oppo's internal, authenticated service tools. Because there is no unauthenticated/leaked programmer available for this specific platform, any free tools (like bkerler/edl) or even commercial boxes fail with a hard "Firehose auth failed" loop. The Conclusion: The "In-Depth Test" application was never a local exploit; it was merely a thin UI wrapper designed to round-trip your hardware IMEI/Serial to Realme’s backend. The actual authorization happened server-side, where Realme generated a cryptographically signed unlock token specific to your device's unique hardware signature. Without a signature matching the OPPO Root CA embedded in the silicon fuses (QFPROM), the bootloader will absolutely reject fastboot flashing unlock, returning 已进入Fastboot 长按电源键6~10秒或重装电池退出. There is no local software exploit possible. There is no EDL bypass available. Continuing to allow threads asking "How to unlock bootloader?" just invites scam links, fake malware tools, and unnecessary spam. I highly recommend the administrators to auto-ban any UBL-related questions for the RMX2170 moving forward. The door is cryptographically shut.
