Part 6: How to Recover If the “Fixed” ROM Bootloops

Sometimes a ROM isn’t fixed for your specific hardware revision (there are A37M, A37f, and A37dw variants). Here’s the emergency fix.

Symptom: Boot animation loops forever (over 20 minutes).
Solution – The 3-Button Combo:

  1. Force shut down (hold Power 15 seconds).
  2. Hold Volume Down + Power → Enter TWRP.
  3. Flash bootloop_fixer.zip (this patches the fstab and removes forceencrypt).
  4. If still looping, restore your NVRAM backup, then flash a stock ROM via SP Flash Tool (Download: Stock ColorOS 5.1).

Important: Do not use “Format All + Download” in SP Flash Tool. Use “Download Only” to preserve your IMEI.

Step 3: The "Post-Flash Fix" (Crucial)

After flashing, do not let the phone boot normally.

  1. Disconnect the battery (remove back cover and unplug the ribbon cable).
  2. Reconnect the battery.
  3. Boot directly into Recovery Mode (Hold Volume Down + Power).
  4. Perform a Factory Reset. This fixes the "encryption unsuccessful" error common on ported ROMs.

Cause: Wrong ROM version (Firmware mismatch) or corrupted download.
Fix:

  1. Boot to TWRP → Wipe → Dalvik, System, Data, Cache.

  3. Flash no-verity-opt-encrypt.zip (disable forced encryption).
  4. Reboot. First boot takes 10–15 minutes.
