hp elitebook 745 g6 amd bios unlock

[leks2012]

Hello everyone,

I’m trying to restore a **HP EliteBook 745 G6** with a corrupted BIOS. Here’s the critical info:

### **Device Identifiers**
- **Motherboard**: 6070B1487701-MB-A01
- **Serial**: `5CG0012F86` | **ProdID**: `8ZE82UP#ABA`
- **Build ID**: `19WWTLBT601#SABA#DABA`
- **Feature Byte**: `3X476J6S6b7B7H7M7Q7W7m7saBaEapaqauawbUbhcAdUdpdqfPhKhkjhk8.g`
- **CPU**: AMD Ryzen 5 Pro 3500U

### **Symptoms**
- Powers on (fans/LEDs), but **no display**
- No keyboard/touchpad response
- EC seems unresponsive (power button dead)

### **Attempted Fixes**
1. Reflashed BIOS via CH341A (multiple dumps, no success).
2. EC reset (battery disconnect + 60-sec power hold).
3. Verified voltages (3.3V present on BIOS chip).

### **Request**
- A **clean BIOS dump** matching:
- Board: `6070B1487701`
- **Build ID**: `19WWTLBT601#SABA#DABA`
- Feature Byte: `3X476J...` (full above)
- Advice on EC firmware (IT5570VG?) if suspected.

### **Attachments**
- [High-res motherboard photos](link) (BIOS chip + labels visible)
- Current BIOS backup (available if needed).

**Thank you** for your expertise! This community is my last hope.
