Hi. My iPhone 7 Plus Keeps rebooting. Boot loop. It Turns on to white apple logo and then shuts off and then turns back on. Keeps doing that repeatedly. I’ve already tried a restore from my computer and it resets and shows the reset bar but then comes back to the reboot screen. Please Help. Thanks in advance.
In my experience the most common cause of a bootloop an an iPhone 7 is the Audio IC chip… or rather the lack thereof. This chip will loose some of its solder joints similar to how the touch IC would on the iPhone 6 plus. Here are some images showing where it is and how to get to it.
The only real way to fix it is to remove this chip, re-ball, and re-solder it back. This does come with some risk and should only be done by an experienced professional. Also, with some of the later updates of iOS, most iPhones will boot up showing only a black or white screen before showing an Apple logo. This alone doesn’t indicate any kind of issue with your phone.
I have not worked on the 7 plus yet but have had this issue with several of the 6 plus iphones…both of which require board level repair. 1st repair is to replace the Tristar (U2) charging IC Chip and 2nd is to verify proper voltage on NAND (Hard Drive) (Reball has helped). It could be a software issue as well I imagine but if you are not able to restore, have restored with same issue, or get an error message on Itunes, I think your best bet is to take it to a good repair shop or to Apple if under warranty.
on iOS 11 you don’t test out screens…. replace everything on the lcd and install the new lcd with every screws, close up the phone. then turn on. note: there are many diff kinds of screens that doesn’t work with iOS 11. if problem continues, check every wiring on the new lcd…. or try putting everything on old screen or working gem screen… in some cases i hard reset 3 times and plug in the charger.
Reinstall the screen with the front camera detached and see if that kicks it out of the loop. The cameras are very fragile and often times when the phone gets hot, It damages the camera and causes that to enter boot loop. If this works, simply replacing the front camera will usually fix the issue.
Please try to use 3uTools to restore your device. Hope it would work for you.
Hi there try this, Press and hold the Power button and Volume Down button simultaneously until you see the Connect to iTunes screen. Do not release the buttons when you see the Apple logo because you will need to enter recovery mode first. You will then be prompted with the option to Restore or Update. When holding the buttons down it should take around the 20 second mark.
