White Screen of Death- Best way to avoid a second time?
I did a overhaul of an iPhone 3GS. I changed the back housing, replaced the battery, and installed a new headphone jack assembly to fix a unresponsive power button.
Disassembly and reassembly were all successful except I got the white screen of death when completing everything. Looking around yielded that the LCD was broken from me not turning off the phone when diassembling.
The thing is, the power button was unresponsive before I attempted repairs, so naturally turning off the phone was impossible. I let it run until the battery died.
After reassembling- the power button now works and when pressed brings up a white screen. The home button is unresponsive- but the phone was in pre-activated mode (emergency calls only) so I have trouble trying to interact with it.
iTunes recognizes the phone (prompts- insert SIM)
I have bought a new display assembly (home button + lcd + digitizer) for sake of convenience- I assume I might have broken the whole assembly when I took the phone apart with a suction cup.
My Question ishow can I avoid breaking the second LCD? Now the battery works fine and I fear replacing the new display assembly would break it.
Thoughts / advice is greatly appreciated!
Is this a good question?
