There is also CS-FLUX which seems to be flux specially designed for BGA rework by a laptop repair workshop. My Macbook pro has been having screen glitches randomly with lines appearing on the screen and then it suddenly shuts down. YouTube this one was helpful but didn't end up working for me so I put only one of the RAM cards back in and it started working again. Simple Fix for: MacBook Beeping won't turn on. Amtech flux is very good for this job but quite expensive (on ebay most Amtech flux that is offered for under 25$ from China is low quality Chinese copy). I just had this problem and looked up videos to help.
If you intent to do just a reflow you will definitelly need apropriate flux to be injected under the GPU. A reflow (heating of the solder balls under the GPU at around 250 degrees) could fix the problem temporary but in order to have a permanent result you need to remove the GPU and replace the solder balls (reballing).
