Thank you very much for this guide.
Could you also describe what tools (soldering iron etc) do you use?

I use a Radio Shack digital soldering iron. It's nothing special but it's temperature controlled and has a fine point.

I made some more overlays

here is Exynos4210



This is from OMAP 4460, but I'm pretty sure it applies to OMAP 4430 as well

Sorry Adam, you have a great writeup, but this is really a BS statement!

-- You can easily unsolder a BGA chip with a $5 micro-blow-torch! You just have to make sure you shield the surrounding components from the excessive heat. Put a small piece of copper (a penny?) on top of the chip, then put a piece of low-temperature (lead-free) solder on top of the coin, so you can get an idea when you have enough heat. Continue 10-20 seconds. Very carefully try to jam a few sharp toothpicks under any space between chip and PCB. Never bend!

This technique is well known and well demonstrated on YouTube, ever since the HP/Nvidia scandal of video chips falling of the MOBO after dust blocking the fan intake with (purposely) under-dimensioned and faulty heat-sink design.

The problem is getting it back ON! Then you need to invest in a professional heat plate and re-balling grid.

^^ good idea! I've always used a high power and small heat gun. It works for 99% of the pads, but I always lose 1 or 2. I never intend to put them back on.

This is the wrong place to post that. And it does not really make sense that you did this in context.

Unsoldering a BGA is easy.

Doing it without causing unrecoverable damage is a different story. Same for resoldering it back on.

However it is getting easier nowadays - temp-controlled hot air rework stations have dropped drastically in price - http://www.amazon.com/Updated-Aoyue-...ref=pd_cp_hi_3

Also, reflowing a BGA without removing it (such as for Xbox360 RRoD fixes) is a LOT easier than remove-and-replace.

Also - my personal favorite deal in terms of soldering irons is http://www.amazon.com/Aoyue-937-Digi...1244730&sr=1-1 - The Aoyue 937 is amazing considering it is <$50.
