Chosen Solution

So i have replaced a Iphone 6 Display (pre-assembled) and everything worked well (tested fron camera, homebutton and stuff). Suddenly my friend told me, that somehow the device is not working and when he gave it to me (the same day) the iphone was stuck in a boot loop: https://www.youtube.com/watch?v=wDas7WcM… I tried to disconnect battery and also the reset with home button and power button, but still the same problem. Funny thing is, that I cant put it into DFU (it seems), because the device is restarting too fast. After that I tried to take another Display (from my working device) but the problem is the same. I did not use the wrong screws (3 smallest bottom, biggest on the right, middle left)! Please ifixit and community help me out :( Thanks in advance. Philip

The same thing happened to mine when i replaced my screen and put a new cable for my proximity sensor and front camera. I didnt know what to do, i tried so many things and it finally worked when i tried my old sensor and camera cable with my new screen. I got a new cable because my sensor wasnt working but turns out the new cable didnt work at all. It may not work for you but it did work for me and its worth a shot.

Exact same problem. Took the front camera out of broken screen. Replaced it in the new screen and boom… everything works perfectly!! It was a bad front facing cable. This is the last time I buy a full assembly from ifixit.

Had the same problem with my replacement digitizer from ifixit. I swapped my front camera, speaker and ambient light sensor and it fixed it. Works great now.

Its acting like it has a battery connection issue or an issue with the battery gas gauge circuit.

I am currently having this issue… The iPhone would show apple logo then immediately go to dfu mode then power off and repeat. I have now plugged the device into the wall using my iPads transformer and with that in place the device does not power off now but it stays stuck in dfu mode now. I try to put the device in restore mode with iTunes logo but I am getting no luck. Here are some possible explanations:

  1. The juice of charge doesn’t surpass a certain % just stays at the level of being able to just power on (I tried this with battery disconnected from MB and was getting same result: power on-dfu-off
  2. Completely corrupted software. Right now. I’m leaving the device in dfu mode with the iPad charger. Hopefully will be able to restore. Will let everyone know soon. UPDATE: SUCCESFULLY OUT OF BOOTLOOP! USE AN IPAD CHARGER!

Do you still have the old screen? If so try that again to make sure its not the screen. Also what i would do is unscrew the LCD ribbon plate and see if that changes anything. Its not a blue screen so luckily its not a issue with the mobo (I hope for you). If its still the same issue you can get to DFU mode by unplugging the Battery and holding the home button before plugging it back in.

hello do you have solution ??

Did this get fixed! It happened to me and I really want my phone back

Philip I have same problem after changing my screen. Initially, phone would not power up after screen change, but unplugging the battery got it going again. Now it reboots just as you explained. One thing to add. I let it reboot until the battery died. When I pushed to power button it showed me a stable battery mode message indicating I needed to plug in phone. As soon as I plugged it in it went back into continuous boot mode. Headed to repair store today.

I had the same problem with a screen that came with front camera and proximity sensor. by replacing it with the original one (Including the ear piece) it worked.

My issue was (or appeared to be) the sensor assembly. I brought a COMPLETE replacement part for an iPhone 6G. Once replaced, Apple Boot Loop continued, DFU mode did not work, nor did a hard reset, just a continual boot loop. I removed the stock sensor, camera, shield plate and home buttons from the complete part and replace them with the originals from the broken screen. First boot worked - unsure if this could be a boot hardware initiation issue, maybe some of these component parts fail and cause the Apple loop. Hope that helps, Will RocktScience.co.uk

I’ve seen this happen on a few iphone 6’s in the past when one of the three connectors (lcd,digitizer, camera) are not plugged in all the way.

Nothing is work for me I tried everything everyone suggested on here but its still not working but i also added a new home button so that may be throwing it off but I tried rebooting it with it unplugged and it did the same thing but Im doing a screen replacement Iphone &.

i replaced my screen and my battery and ive tried everything on here but i still got bootloop i tried dfu and also tried updating my firmware and i dont have anything im still in bootloop when its in restore mode it stayes on but as soon as i try restoring it .. it goes back to bootloop

My iPhone 6s kept restarting every few minutes till I replaced the new front camera with original one, fixed
