回答“How to fix iTunes error 9”OK, this is what worked for me. background: I just replaced the screen on my SE. went to boot it up and it was stuck on the apple symbol. plugged the phone in to my macbook, started itunes -which said a restore was needed. did a restore and got the error 9. tried to restore again and same problem. did some googling of the problem and ran into a random comment where some user posted a slab of text but one thing that was different was that he said he tried "plugging in headphones" I dislike the bullsh!t of iphones (error codes- dodgy "upgrades", etc) and usually use android. my kids use apple phones because the phones are simple and the cameras are pretty decent. so I tried to restore again and this time I inserted and then removed a headphones plug in and out of the iphone. maybe it was a fluke. maybe itunes kicked in properly and worked, maybe because i was facing north and had just sacrificed a chicken to Steve Jobs. who knows?? but it worked and my iphone restored.

回答“"No Service" even without a SIM”I had this problem with a 3g. I installed a really old firmware as the new firmware "upgraded" the baseband. this caused problems with the baseband/connectivity for some reason.

回答“video graphics and boot issues”I've done GPU reballing ith a hot air gun on G3 laptops. I bought a replacement G5 as my regular G5 died from faulty ram sockets. the new G5 had garbled graphics. slightly usable but garbled. Yesterday I decided to reflow it. followed all the fregac steps as above and as I have previously done with laptops (fixed 5 in the past). waited an hour then added thermal silverpaste. red LED came up!!! added more thermal paste, again 4th red LED. this morning I tried pmu reset and change battery and still red LED. I took the heatsink off and the little bit of plasticy stuff that goes betweeen the heatsink and the gpu and I flipped it over. replaced heatsink, and a touch more thermal paste and fired up the machine and it booted to GRAPHICAL PERFECTION!!!! very stoked with the outcome.
