Good instructions, thanks. I dropped mine on the floor and was afraid it was broken but upon opening it, turns out the battery just jolted loose from its contacts. I put it back with a big wad of masking tape to pad out the extra space so hopefully it won’t fall out so easily next time.
Never mind, just needed a reboot. Whew!
I'm still having trouble - I bought an LCD+digitizer and have put the new one in. The touchscreen still doesn't respond. I've checked all the connections and all seem secure, including the small square one on the back of the LCD in step 9, figure 3 that's not mentioned. Any idea which is the actual connection of the digitizer? Thanks.
If you break your touchscreen digitizer, DO NOT buy the separate digitizer thinking it's cheaper. I made this mistake only to find that the LCD is glued permanently to the digitizer and it's impossible to separate them even after heating. Broke the LCD. Definitely buy the entire LCD+digitizer assembly.
