Hi Bro Attention, when you turn on you must boot the computer without a hard disk and go to the computrace configuration in the bios, you must permanently deactivate it, if you do not do it the computer...

hoaca388's file is good, I reached same identical file. Check pin to pad solder joint, blown away or moved components. Also, should have been done before soldering chip back on board, verify flashing by taking another reading and comparing to hoaca388's file. Do not rely on automatic verification. Do not rely on clip, always take three good readings and compare, all should be identical, you are messing with the bios, could brick your laptop.
