On startup apple logo and turns off --loop!

Good morning,

I had my ipad 7th with broken glass, I had it repaired by a no apple technician, and after the replacement it had the ghost touch defect, after which I reported it to him and solved the problem by installing the virtual home button . Everything worked fine even though the physical home button didn't work. After the first update the iPad does not start anymore, the apple logo appears and turns off and continues like this until the battery runs out. Has this defect happened to anyone? At this point I was curious to disassemble it and to my enormous surprise I saw that the fixing screws of the LCD and the glass connector cover shield were missing. Since the physical home button is out of order and itunes can't see the ipad does anyone know how to put it in DFU mode, or how to restore it?

hello EdoS,

it looks like you have handed over your device to a scammer who is getting dubious knowledge from YouTube. It's sad, unfortunately quite common. Rule one: never ever repair your iPad in an unconfirmed repair shop. This fragile device is easy to break in the wrong hands. Requires knowledge and years of experience in repairing microelectronics. But, to the point:

Touch problems in the ipad 4,5,6,7 series, where the LCD matrix is separated from the digitizer, are related to the extremely low quality of the Chinese, polycarbonate interchangeable glasses with a glued digitizer. (I will not mention the electronic reasons at this stage - which are also very important). Replacing the touch screen in this series, only 4-5 of the 10 screens are usable.

I wonder why the button is disconnected and the touch function is lost. Correlation known from iPhones. Did your Home button also get damaged when the original screen was destroyed? The Home button is connected with a different ribbon and all signals are separated. If the button does not work, the tape itself is probably damaged or the port on the motherboard is not properly tightened. And finally the connectors cover: their absence and the screen screws you write about are evidence of your mechanic's sloppy and rush. That's a bad thing for a microelectronics technician. Last question: did your iPad work when you gave it in for screen replacement?

Boot loop problems usually arise from problems with the motherboard. Untrained hands make microcracks when removing (unglue) the motherboard from a housing. Commissioning after updating requires automatic initialization of the installed components - if this does not happen, the system waits via pre-programmed time unit. If this does not happen, the system says "time-out" and reboots automatically. This could go on forever. If it concerns non-essential accessories (such as compass, flashlight or Home button) the system will not register the component in the new build and it goes ahead. On the other hand, if the initialization hits a damaged component causing a short to ground - the system is unconditionally restarted. Another important reason is the problem with allocating a new system in memory or updating user data. In this case, a restore with the factory settings will suffice.

there are service methods to do it without a button, but it is not a home method by an untrained person. The first is the service pinout of the control pins on the motherboard. Closing the circuit places the processor in a service state. The second method is to use the button's port and close its circumference manually. As a result, we can get to the service modes (there are three: the first, second and third level). I do not recommend this for fun at home.

I advise you to give your iPad to the right hands. I know two good studios in the US: NorthridgeFix, CA (NorthridgeFix.com & IpadRehab, NY (ipadrehab.com) or in the EU: studio.N / east.EU (studionapraw.pl) & RESQ / west.EU (resq-repair.com). You will certainly find help there.

  • regards,

I am very grateful to you for your relatives, and I understand that I was wrong by going to a scoundrel who pretended to be a technician.

I tried replacing the home button and it doesn't seem to work. I'm just waiting for the missing screws to be received for further testing.

For the other reboot methods without home button, I think I don't understand what they consist of!

Same happened to me, I connected the iPad to iTunes and put into DFU mode, ran the “Update” option (didn’t want to restore if i didn’t have to), and it worked!

If update doesn’t work, I suggest trying the “restore” option that pops up.

Will wipe all data and setup as new iPad, requiring you to enter your Apple ID and password (if applicable) to set it up again.

Instrux for DFU mode:

These instructions work for all iPhone models before iPhone 7 (iPhone 6s and earlier, including 1st-generation iPhone SE), along with all models of iPad (with Home Button) and iPod touch.

  1. Plug in your iPad or iPod touch to your Mac or Windows PC.
  2. Make sure that iTunes (macOS Mojave) or Finder (macOS Catalina and later) is running.
  3. Turn Off your iPad or iPod touch if it isn't already.
    1. Press and hold down the On/Off button for 3 seconds.
    2. Swipe the slide to power off slider to the right.
  4. Source: iMore
  5. After the device has been turned off, press and hold down the On/Offbutton on the top of your device for 3 seconds.
  6. Press and hold down the Home button on the front of your device while still holding down the On/Off button.
  7. Keep holding both buttons down for 10 seconds. (If you see the Apple logo, you've held them too long and will need to start again.)
  8. Let go of the On/Off Button but keep holding the Home button for about 5 seconds. (If you see the "Plug into iTunes" screen, then you've held it too long and will need to start again.)
  9. If the screen stays black, that's it! Your iPad or iPod touch should now be in DFU mode.
  10. Source: iMore

At this point, iTunes or Finder should show you an alert saying it has detected your iPad or iPod touch and will allow it to be restored.

Reminder: If you see any logos on your device, you might be in Recovery Mode, but you're not in DFU mode. If Recovery Mode works, great. If not, try for DFU Mode again.
