I'd estimate that I've spent at least 100 hours soldering things in the past few years, even some larger surface mount parts by hand. All that to say that I'm confident in my ability to solder reliably well and fairly proficient for a hobbyist.

But this thing is a pain. I spent 20 minutes trying to get the first solder point made with it lined up with all the pins. I'm about 2 hours in now. All the pads seem to be connected without bridges, but I get no picture on the screen. (Yes, I've rotated the polarizing film, and I did not forget to cut the traces.) I'm going to have to give it a rest and figure out what to do next at a later time.

If you want to try it, I'd recommend the follow tools and supplies:
magnifying glass on a stand
tweezers
a non-cheap soldering iron (mine cost ~$100)
solder wick
liquid flux
solder sucker
patience

Spent hours trying to install this, in two separate Pockets. Don't waste your time. Buy an LCD screen replacement instead of that backlight/bivert setup you were planning.

Got this installed surprisingly well the first time then realized that I forgot to sever the 2 traces that are of course directly under the chip. After pulling it and cutting the traces I could not get the chip back in and lined up well enough to avoid bridging and had to desolder and reattempt so many times the tiny capacitor the chip bridges to fell apart and the pads started to lift. The pins you need to bridge on bottom are TINY, you will likely want lighted magnification and definitely a multimeter to test continuity if you want to attempt this.

In the end I have decided to scrap this board and just do an IPS build. Not too butthurt about the $15 for this chip and a backlight, but having to shell out $40 for a refurbed board or searching for a cheap scratch and dent is very lame.

Apparently there is a version of this on a ribbon rather than a PCB that would have been much easier to install, I recommend getting that one if you want to go bivert/backlight. Just be aware that going the cheaper route may end up costing you twice as much as just going with an IPS from the start.

Didn't work, wasted about 4 hours of my time and a couple of polarizers while trying to figure out why nothing shows up on screen. Not sure, but the flip-flop chip on my bivert module only has 5 pins whereas one pictured on the item page has 6.

I botched two gameboys trying to use these. Way too small and they just don't seem to line up with the libs right no matter what. I've tried this mod multiple times and never been able to get a clear image and always end up doing it over so many times I damage the board. Waste of money.

The Bivert Module is very small, took me a couple tries to get it soldered properly but it works great.
