Nokia TA-1235 Flash File – Infinity Best Setup 1. Device Info

Model: Nokia TA-1235 (Nokia 2.4) Chipset: MediaTek MT6762V/BB (Helio P22) Year: 2020–2021

2. Recommended Flash File Use stock, untampered firmware (full ROM, not just OTA). Best source: official Nokia care package or trusted mirror. Key files needed (Infinity CM2):

Preloader / DA (custom DA for auth bypass) Scatter file (from stock ROM) System, vendor, boot, and userdata images

✅ Best working version example: TA-1235_MT6762_V1.250_10.0_Stock.zip (Android 10, Dec 2021 security patch — stable for flashing)

3. Infinity Box / CM2 Settings (Best Config) In Infinity CM2 (New Tool):

Select MediaTek → Auto Detect Load scatter file from extracted ROM Enable → “Skip auth” (for preloader) Enable → “Force DA boot” Flash Mode: Download (Full) – untick “Userdata” if preserving data Use custom DA → included with Infinity (DA_6762_ta1235.bin from support area)

Hardware connection:

Testpoint is usually not required if preloader handshake works. If dead boot → TP to GND to enter BROM mode. Use USB 2.0 port with original/short cable.

4. Flashing Steps (For “Best Result”)

Charge battery > 50% (or use power supply on D+ line if faulty) Open Infinity CM2 (v2.0+) Load scatter → tick required partitions (Boot1, Boot2, system, vendor, etc.) Click “Download” or “Format All + Download” (⚠️ will wipe IMEI — back up NVRAM first!) Connect phone in power-off state If no auto detection, short testpoint → connect USB instantly Wait for 100% → green ✓ → Disconnect and power on
