Ok, I am a newbie here, and it should be considered that I know absolutely NOTHING these phones because, honestly, I don't! I will try to be as complete and concise in my details of what is happening with the phone! Also, I have searched several threads in this forum, and some were "close", but not exactly what I was experiencing, so forgive me if this is in another post somewhere....I didn't find an answer that I could understand! Thanks for being patient! Ok, so I bought this phone from Craigslist, and the guy said he broke the screen, and "when he replaced the screen, it wouldn't turn on"! I picked up the phone and two batteries for $30.00! Figured it was worth trying to fix for that price! I noticed immediately that his "new" lcd screen was cracked, as it was a very light golden color, and I actually found a crack in it! I purchased a new lcd screen, digitizer and plastic bezel, so all I had to do was screw the back (motherboard) to the new setup, and turn it on! Upon turning the phone on, it immediately went to the HTC EVO 4G "white" screen for about 10 seconds, then goes black (shuts down)! I then have to remove the battery to get it to boot the same again. I thought perhaps battery was not strong enough, so I charged overnight.....same issue with fully charged battery! Next, I searched this forum and found how to boot into recovery mode, which I was able to get it to do! I will post the following information exactly from that page to hopefully give you more info: Supersonic EVT3 SHIP S-ON HBOOT - 2.16.001 MICROP - 041F TOUCH PANEL - ATMELC03_16ac RADIO - 2.15.00.05.02 Mar. 8 2011 17:02:15 As far as I know, the phone is not rooted (S-ON......read that on this forum!), and he told me that it has a clean ESN, which I have checked and confirmed that it IS a clean ESN! Like I said before, I don't know much about these phones, and was just buying it to perhaps try my hand at fixing something like this without a major loss of money in the process! With the purchase of the new LCD, etc. I have about $70 in the phone! Can anyone help point me in the right direction as to getting this thing to boot up? Again, I am new, so please assume that I know NOTHING! Thanks for your patience and consideration of this issue! I'm sorry for the long post, and if I missed any important information, please let me know! I look forward to reading your suggestions! Thanks again, and have a great day!
