Error 27 or 9 with blue screen - can't start
I bought an very cheap iPhone 5s with the error discripton "bootloop". Now it's here and I'm not sure what's the error.
If I start the phone, the screen is black but I can see the backlight. If I hang it on the powercharger, I see the Apple logo.
So I decide to restore it with iTunes. iTunes recognizes the phone but I can't restore it. On normal restore I got error 27. iTunes say it's waiting for the phone -> on the iPhone I can see the apple and the progress bar with 0% and around 1 minute later, iTunes show the error 27.
In the dfu mode I got error 9. It's the same. iTunes want to restore the phone -> on the iPhone I see the progress bar with 0% but then I see for 2 seconds an blue screen without any text. The iPhone restart and iTunes show me error 9.
I vacillate between a defective battery or a defective screen.
Can anyone help me?
Hello again, today I opened the phone and definitely it was not opened yet.
At first I removed the screws that covers the screen connectors -> error 9 (restore) and error 27 (update).
Then I disconnected the display, the camera, the gsm antenna and the other connectors near the screen but I got error 9 again. Is it at all possible to restore the phone without connected screen? I tried to find the faulty part.
I can't imagine that the phone is broken without exposure.
At next I want to change the battery.
My PC is definitely ok. I tried to restore my old iPhone 4 and it worked great.
Any other ideas?
Is this a good question?
