My Samsung Galaxy S7 Edge decided to roll over and die. I lost my ROM section and nothing I could do would work to fix that issue. I then finally after weeks of testing and playing around came to the conclusion that the famous crappy new no lead solder had given out somewhere. (As it is very common, actually way too common!) I was going to try the oven heat method and try to get the motherboard to reconnect at the bad joints and it does work, but I would probably just make things worse… (Like burn down the home front.)
I ordered a rebuilt board from Aliexpress and in a few weeks it came. In fact just yesterday, I got the motherboard. About five thousand rubles ($75) and a year guarantee….Today I installed it…

I used the video above to preform the operation and it worked just fine… 😉
I have to say that Aliexpress is a fabulous company to deal with….and the store I bought from even gave me a new rear cover adhesive free…
Therefore, I am a happy camper and have my favorite phone back. It is slightly nerve racking to take apart a small cell phone with my huge fingers, but just take your time and it will happen. The only thing that I can say is that taking the back cover off was very hard. The glue was strong and I felt like I could break the rear glass cover at anytime. I had a suction cup that helped to give some pull on the back panel and it is a must to do the repair….that rear glass is thin…
It has been a good day and I like repairing computers and cell phones…
