My friend give me his old Xbox 360 and my challenge was to repair it :)
Very well! The explanations on the guides are clear!
The X-clamp are tricky to remove but after that, you just don't need them anymore so it's ok! ;)
For the "reflowing" part of the guide I used a hair-fan instead of an hot gun... And all goes well!
Use the Ifixit App if you have an Ipad it could be pretty practical when disassembling!
