Method A: Using SP Flash Tool via Infinity CM2 (Standard)

Most Infinity users prefer using the integrated SP Flash Tool module because Infinity automatically handles the SLA/DAA authentication. Part 1: Understanding the Nokia TA-1235 & Flash

  1. Launch Infinity CM2 Software.
  2. Go to "SP Flash" tab.
  3. Click "Scatter Loading" and select the MT6762_Android_scatter.txt from your firmware folder.
  4. Check only the following partitions: (Do not check Preloader unless necessary)
    • Default: Boot, System, Vendor, Userdata.
    • For Dead Boot: Also check Preloader + LK + Tee.
  5. Download Agent: Select the MTK_AllInOne_DA.bin that comes with Infinity (located in `C:\InfinityBox\CM2SP\DA).
  6. Auth File: Click "Auto Detect" – Infinity will send the correct authentication certificate.
  7. Connect the Phone:
    • Power off the Nokia TA-1235 completely.
    • Hold Volume Down or Volume Up (varies by firmware) and plug in the USB.
    • Infinity Status: Should say "Preloader: MT6765... Auth Bypassed".
  8. Click "Download" . The firmware will flash in ~3-5 minutes.
  9. Once done, unplug, and press Power + Volume Up for 15 seconds to force reboot.

Part 7: Preventing Future Soft-Bricks

  1. Never downgrade Android version (e.g., Android 10 → Android 9) without a full format.
  2. Disable OTA updates if you have a modified system – official updates expect stock recovery.
  3. Backup NVRAM using Infinity (Read Flash → NVRAM partition) to save IMEI & Wi-Fi MAC.

Post-Flash Instructions

After successfully writing the nokia ta-1235 flash file using infinity, do this:

  1. First Boot: Takes up to 10 minutes (Android optimizing apps).
  2. IMEI Check: Dial *#06#. If null, use Infinity’s "Repair IMEI" module (enter original IMEI from the box).
  3. Factory Reset: Go to Settings > System > Reset Options > Erase all data (for FRP removal persistence).

1. Identifying the Device & Chipset

Before downloading any file, you must understand the hardware. The Nokia TA-1235 is a Unisoc (Spreadtrum) based device.

  • CPU: Usually Unisoc 6531GE or similar.
  • Flash Tool: The industry standard for repairing these via PC is Infinity-Box (CM2SP2) or Spreadtrum Upgrade Tool (SPD).
  • Interface: You will need a USB cable (some models use a proprietary USB cable like the "Nokia USB" serial cable, while others connect via standard Micro-USB with drivers).
