I'm pretty new to this forum in terms of posting, I've mostly been a lurker to find all the answers I need, but on this one I'm stumped. I have a rooted Droid A855, long story short I disassembled it to replace the digitizer and I ripped not 1, but 2 ribbon cables. Looking like the LCD and the speaker cables. Instead of searching all over for replacement cables I've just decided to get a new one. I can't upgrade just yet so I've been looking at another A855 Droid. I found a fairly cheap Droid with a bad ESN. My question is: If I take the motherboard out of my phone and transplant it into the bad ESN phone, will my ESN be in that phone I just purchased? My Droid is already rooted and customized the way I want and if this is possible, it seems like a pretty good choice. Thanks.
