I spent the last few days trying to unlock it! However, when I tried to remove the EC bios, I messed everything up! Some resistors moved out of place and I'm not sure about their position and their values.
Could a friend of mine send me a photo of this area (photo below) and, if possible, the value of the resistors in red.
Thank you in advance for your help!!

Where those resistors?
top / bottom i can check

Hello,
here's the situation:

• Flashed the file
• Got an EC error
• Desoldered the chip again
• Tried to flash externally
• W25Q256JV was damaged
• Bought a new chip
• Flashed the unlocked file from here onto the new chip
• Still got an EC error
• Checked and resoldered all points

Now the Caps Lock LED blinks white seven times.
Is the hp now broken?
