Why doesn't my phone boot or start without battery with power cables
Actually my phone flashes Apple logo and then restarts the same thing continuously till battery is drained and it doesn't start. Don't know what happen to phone. Got up in morning saw my phone when connected to charger it showed battery symbol with 3 red bars in it. After an hour of charging this loop thing came up. Tried all method of restoring/updating through iTunes but phone gets restarts when download bar appears & iTunes throws error 9. Tried changing battery but no use and also tried heating phone that too no use. Actually I have two issues :
1. Why is my iPhone in continuous boot loop.
2. Why doesn't my phone boot or start without battery with power cables.
Came to know know about 2nd issue while I was searching solution for my iPhone boot loop and then asked my friend his iPhone 4s and took his battery in my phone but didn't work then with just power cable connected (without battery)to my friends iPhone and it started to show Apple logo. So I tried to do it on my phone without battery n just charger but no logo came. So help to revive my iPhone back to life. YouTube link : https://m.youtube.com/watch?v=66aTUgxPx_....
