Device only booting to apple logo. Wont read on PC
Looking to fix up an Apple device, for which im under the impression of board level failure. The device will turn on, but only make it to the apple logo. the failure was sudden death, as per the apple standard. Middle of a text, device died. booted to the apple logo, then went black and got no signs of life. battery replacement gets power to the board, however, only gets to the apple logo.
I can boot to recovery mode, but the device wont post to the PC, so i am unable to reload the software via regular means. i attempted the charge port replacement, which did not help the computer reading the device. (Yes im using apple OEM cords that i use with every other software reload on apple devices, in a USB3.0 as well as a USB 2.0 slot) it is not Cable, or port failure.
If anyone has a tutorial on this issue, i would be happy to learn what needs to be done to fix this. Thank you in advance for any productive answers.
