Answer to: Wont power up after screen repair?Turns out that if you disconnect the lcd, digitizer... (or anything else) FIRST, instead of the battery, you are going to find yourself with a broken logic board, so, you have to replace it too. So, if you are going to replace the lcd o digitizer, disconnect the battery FIRST on disassembly, then lcd and digitizer, and reconnect the battery LAST.
Answer to: Wont power up after screen repair?Hi, no, I did not find a solution, but to replace the entire logic board, so I did that, bought one on ebay for 75 usd, and its working great, but I have another problem now. After finishing assembly, the digitizer presses itself on different places, zooms in and out, keyboard, randomly and very crazy. I guess the digitizer is faulty or maybe I bent the cable flex too much.
