Hy Guys, I know it's a little bit late but I hope to can help someone the same.. In my experiences with iPhones and the "no signal" problem not always is a hardware problem. Especially with updates it happen that the os do some mess.. In these cases (so not hardware problem), I have simply fixed the situation RESTORING iOS with iTunes. Before restore, use iTunes for BACKUP your stuff and then proceed to restore iOS (iTunes will download from internet the ipw and then flash it again on your phone). It's like format an hard drive of a computer and install again the os, like a new device. I also advice to turn off iCLOUD before you proceed. Then BEFORE put back your backup in your iPhone try the sim and check if it work! If is fine then proceed with restore your backup.. I cross my finger for you.. ;)

I have try to search it here on the iFixit store but I haven't found it. So you're lucky on eBay is pretty cheap! You will have to follow this guide till STEP 19: MacBook Pro 13" Unibody Early 2011 Logic Board Replacement I cross my finger for you.. ;)

Seems that you have bent too mach the front assembly flex cables.. You should never bent them over 45 degrees, also a clue is the vertical lines. Unfortunately you have to replace your front assembly (lcd), but this time follow this giude: iPhone 5 Screen Replacement

Hi Jessica! Yep, often error like these behave from an hardware error. This is the guide you need: iPhone 5c Front-Facing Camera and Sensor Cable Replacement A test you can do before buy any replacement is to disconnect, in this case, the front camera / sensor flex and without close the phone, try to boot again. If the problem still continue, try also to disassemble the shield that hold in place the display assemble cables. Cross my fingers for you..

Ciao Gabriele! It could be a software problem and not hardware.. First of all, have done an OS update or install new hardware from when you have notice the bad behaviour of your mouse? Bluetooth device and usb3 hardware have some problem to live together.. Try to un-coupling the mouse in the OS using the Bluetooth preference panel and coulple it again as a new device! If this don't work, You can also would try to reset your P.Ram (shut down the computer, turn it on and before you hear the chime sound hold those 4 key: P+R+alt+cmd till your mac reboot again).

Unfortunately I think is the graphic card too.. One chance to test is the health of your hard drive in case bad sector could leas the OS the bad kext read.. If you can test your Imac this way, prepare a usb thumb with the OS installer using diskmaker x from another mac and a formatted usb external drive and try to install the OS on it. The first attemp to boot to the usb thumb will show you simptomps and probably won't be able to install anything 'cause of the bad graphic cards but If your system go ahead try to full install the OS and see what happen at the first boot.. If the gpu is gone and you're out of warranty the Last resort solution would be to teard down the logic board from the Imac and bake it into the oven as for macbook pro logic board, depends on your skill.. I cross my finger for you.. Let me know..

Hello Festus, you have 2 choice: 1) enter in the recovery partition and format the phone doing this: shut down the phone, the push and hold volume down + power + home till you will see something different from what you are used to. Something like an 80's computer interface. Than choose WIPE DATA / FACTORY RESET take a look at this video: https://www.youtube.com/watch?v=EIGst3ed... 2) When you will have reset you phone, if you still have demo limitation, you have to use a tool called ODIN and flash (install) and original firmware (called stock). You have to search on forum like XDA, because is the only way for give the phone a full functionality.

Error 4005 is related to a physical problem.. In my experience is not really a software problem (maybe only if you use a windows based pc), but due to a bad assembling parts. Probably when you put back together the display and home button you have missed something or done some wrong step..

Hello Amandeep, You are in hurry!!!! You DON'T have tu use your phone after water damage. If is possible: REMOVE IMMEDIATELY THE BATTERY AND DON'T TRY TO TURN IT ON in any case put the phone in a fridge plastic bag with a lot of rice. The amount of rice depends by how is big your phone. Leave it in the bag with the rice at least for 2 days! Unfortunately a lot of hour are gone from your message, the more you have try tu use the phone, the more you have damaged it! Try at first with the rice then if you have a LOT of LUCK your phone will be alive otherwise you will have to give the phone to a technician lab where the phone will be disassembled and the washed with a solution like isopropilic alcohol and ultrasound. I cross my finger for you..

Try to calibrate the home button: Push and hold the power button till you see the swipe icon for turn off the device, the push and hold the power button till the iphone come back to the home screen, now try to use the home button again! If still not work, for well understand what could be, backup everything using itunes and restore the software. Than, use it without restore your backup, as a new ipad and verify the correct or not behave of the home button..
