I'm not sure what is wrong with it. I restored it to factory settings and now when i try to activate it , it keeps asking me for the previous owners apple ID and i don't have his number anymore.. What should i do? Is my iPad pretty much bricked forever? Please try to activate the iPad. If iPad shows this device is linked with abc icloud. Normal Process: Requirement is the POP Invoice of the device.
If you have the bill of this device. Just call AppleCare they will assist you better.
They will remove this within 3 days. Only if device not been stolen or lost. AppleCare need only device bill and tell them you are unable to activate the iPad. Can I use a hot plate to remove an S4 digitizer?
I'm sure most people here know that heating up an S4 digitizer with a hairdryer and removing it that way can be quite a chore. I'm just wondering if anyone has ever used a hot plate to do this instead? Is it a good idea? If so what temperature do I set it to without damaging the S4? Do a hard reset.

By unplugging the logic board you effectively did a hard reset. And also try completely disconnecting the logic board and reinstalling it. The digitizer flex cable seems to be tightly in. It sounds like you might have a hardware or a software issue, try to open up the device and make sure all cables are on correctly by removing and reinserting. It May also be a ribbon connector issue. If that doesn't work you may have to do a restore or a factory reset. Super clean the digitizer contacts and seat them firmly.
I Changed ribbon connector. The first two digitizers were jittery. I returned the first one but since they are so cheap I just bought a third one which I used in the final repair. So there is a small chance that the first two were defective or I didn't seat them good enough but I doubt it. I also might have over-heated one of them in my attempt to seat it on the warped frame.
But the final digitizer is working great and so I am betting on the warped frame being the culprit. Be sure that you are charging using the correct wall adapter like this one here. Also make sure that the charging cable is not longer than three feet or one meter.
There is too much voltage drop for the Smarphone to charge properly on most longer cables. Most of what I see is hardware failures, and this is a common one called 'fake charging' that can happen after water damage or drop damage damages in phones which causes a hardware fault on the logic board.
I had an S3 mini lately that had a similar problemcharging okay but the battery percentage never went up or down S4 fake charging is probably a burned U2 charging ic chip, just like in the S3. I have seen this a lot this year.
I know it's kind of late to answer this but to anyone who have this issue, it's your charger cable, in the cable there are a few wires for different things, I don't know exactly which does what, but some of them are for charging , some of them are for USB connection , I think those wires for charging are damaged and when you plug it in , Smartphones thinks it's connected to the charger because of those wires that are not damaged yet The best part of their training is they provide training practically DIY step by step.
The technical support given is also worth mentioning. Because of them, I am a very successful technician today. And spare parts supplier information.
