iPhone 7 apple logo reboots every 3 seconds
 

iPhone 7 apple logo reboots every 3 seconds after simcard along with gevey been removed after been stuck into sim reader.

A technician remove the tray along with the gevey and sim when the phone was on which it shouldnt had been that that way, the phone should be off
I guess thats what causes the problem, he check the sim reader if its damage but the sim reader is ok, he disconnected the battery for 10 minutes then reconnect and its the same apple logo stuck and rebooting issue after 3 seconds.
I restored the phone through itunes it restored successfully and its the same problem, Any suggesstions????

hi dear
when you restored the iphone did it activate also?and if you please send me the screenshot of about display then i can suggest you

When i restored the iphone, it restored successful but do not startup to activation screen, it only reboot to apple logo then reboot again and again and again

Keep plug in charger and see whether working or not

I have done that already the same day, it also take the recovery mode command and the itunes cable stay still without restarting. When it comes from that mode it starts to loop and restart again

put in dfu mode and restore with itunes

I already done that.. Its the same thing

You can ReiBoot. It is a very powerful tool that forces reboot your iPhone without losing data.

one question i want to ask that you said that the technician unpluged the battery for 10 mins. did he unplugged the battery in front of you or not. if yes than try to change the battery if no then he might have changed your battery. in both cases you just try to replace the battery. that might helpful to you. reply if you find it useful.

You really should take your iPhone 7 to Apple Store or other authorized service center. It must be a hardware problem.

100% hardware may be inner sim slot sort ground any pin

This is Main Board Issue.
 

Yeah this is little problem iPhone 7 randomly restarting

It's Sounds like a hardware problem with your main iphone7 board. This is the most common cause of unexpected restarts.

You must get a genius bar appointment at your nearest apple store and tell them your issue. They will most probably replace your phone.

If you don't have a local Apple store number, contact AppleCare (800) 275-2273 and describe the issue to them.

It's within the realm of possibility that it's software related, but it's rare for software issues to cause this. If you want to rule that out, perform a restore and set it up as new, then monitor for continued problems.

%100 hardware problem
may be power ic...

change power ic this be done , today i done one this problem via changing power ic
