Issue 1: Boot Loop After Flashing ROM

Cause: Wrong ROM version (Firmware mismatch) or corrupted download.
Fix: Key Features of the Custom ROM:

1. Boot to TWRP → Wipe → Dalvik, System, Data, Cache.
2. Flash correct ROM for A37m (not A37f).
3. Flash no-verity-opt-encrypt.zip (disable forced encryption).
4. Reboot. First boot takes 10–15 minutes.

Bug 1: Camera Shows “Green Lines” or Crashes

Solution:

• Download Open Camera from Play Store.
• Go to Settings → Camera API → Force Camera2 API (Legacy).
• Disable “Face Detection”. This is a kernel-level buffer issue; Open Camera bypasses it.

Should You Use a "Fixed" ROM in 2024?

Yes, but with caveats.

Pros:

• Security: You get security patches from 2022 (vs. 2017 on stock).
• Performance: A debloated ROM runs 40% faster than ColorOS.
• Features: Gesture navigation, dark mode, and app permissions.

Cons:

• Camera Quality: The stock ColorOS camera had proprietary noise reduction. Custom ROMs cannot replicate this. Expect grainy photos.
• Battery Drain: Some fixed ROMs have wakelock issues. Always keep a battery monitor installed.

Part 4: Step-by-Step – How to Flash a “Fixed” ROM Properly

Follow this exact sequence to ensure the fixes stick.

1. Boot into TWRP (Volume Up + Power).
2. Wipe: Dalvik, System, Data, Cache, Internal Storage (yes, everything except SD card).
3. Flash the fixed ROM (e.g., lineage-14.1-20240720-UNOFFICIAL-A37M.zip).
4. Flash the “Fixed Patch” (Many ROMs require a separate fix.zip for camera/RIL – check your download folder).
5. Flash GApps (ARM → 7.1 → Pico) – Do not use Nano or Stock; they cause System UI lag.
6. Format Data (Type “yes”) – This removes encryption leftovers from ColorOS.
7. Reboot. First boot takes 8–10 minutes. Do not interrupt.

Pro Tip: After first boot, reboot again immediately. This finalizes the RIL fix.

Bug 3: Wi-Fi Keeps Turning Off

Fix:

• Go to Settings → Wi-Fi → Advanced → Keep Wi-Fi on during sleep → Always.
• Disable “MAC randomization” (set to Device MAC).
