    Surface Pro 4 - need help with some messed up components

    Hi everyone

    Here is the case that i'm trying to solve.

    (short intro to explain what happened)

    I bought second hand Surface Pro 4 and when I tried to reinstall the Windows it appeared there was the password on UEFI. Seller don't reply anymore. I decided to reflash the UEFI chip to remove the password. So I need to remove the chip from the motherboard first.

    I have basic experience of repair tablets and phones, like battery or display change. So i opened the Surface Pro 4 and removed the motherboard successfully.

    (the issue starts here)

    But when I heated the chip with heat gun and tried to take it out using tweezers, the chip used sucker punch and jumped out of the tweezers hitting bunch of smd components next to it. Eventually I ended up with mess of smd components stuck under the metal frame. I extracted them out of there with the soldering iron but now I need to figure out if it possible to solder them back.

    I have pictures before the disaster and I found similar pictures from the internet. But some components looks so similar to each other I'm not sure if they are really the same. And I think I have less components that it was there before haha I can't find them.

    (what i want to ask)

    Maybe someone can help me to figure out where each component should go. I think I will be able to solder them back, at least I want to try.

    I have a multimeter so I probably can check those components and try to find similar to those I lost. I need something like a picture with comments what I should solder and where. Maybe someone have SP4 motherboard lying around and can take a look what exact components are there in this spot.

    Sorry if i missed any important details. Thanks in advance!

    Schematics and boardview are available:

    L4101~L4103 etc all relate to the MIC and headphone. However, using a heatgun for this kind of work is ridiculous. It's like using a sledgehammer to drive in a nail. Without a hot air rework station, your chances of fixing this are virtually nil.

      Thank you! Yes, of course I would not use a heatgun for smd parts. I used that only for the uefi chip and actually already regret about that :|

      Is that part of the motherboard have same components for both i7 and i5 versions?
