For some reason my Nexus 5 suddenly stopped working. There was no trauma, it hasn't been dropped or anything, the screen just stopped working one day. The screen was already a replacement screen from when I did drop it about a year ago, and it had a bad bleed problem at the bottom of the screen so I didn't mind so much replacing it. While I was at it I also got a new USB charging port/dock connector, as the USB was beginning to be a bit dodgy, and a new battery as I was having it open anyway.
I'm no stranger to replacing parts in phones, laptops and other electronic equipment, and don't generally mess up, but this time, after having replaced all the bits, I'm no further. I've already taken everything apart several times and tried the old parts in all sorts of combinations. I'm sure all the connectors are clicked in good and none missing, but still nothing. When I hit power it gives a short buzz, and the screen gets very slightly lit up, so slightly it's hard to see, but by holding the phone at an angle it can be seen clearly. Nothing else on the screen, no text, graphics, animation, anything. I've also tried all sorts of combinations of up/down/power, also no cigar.
If I boot it in recovery (down+power), connect it to my pc, and do an adb devices it comes up blank. If I do an fastboot devices it comes up with what appears to be the right line.
H:\owncloud\Software\adb-tools>adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
H:\owncloud\Software\adb-tools>fastboot devices
02b58059d0217f13 fastboot
Why the difference? The fact that it comes up with anything at all kinda suggest to me that the mainboard probably is ok, no? So in that case, what's left to try/replace?
I was thinking perhaps the boot partition somehow got corrupted, so I thought I'd try loading a fresh boot partition, but that throws an error:
H:\owncloud\Software\adb-tools>fastboot flash bootloader bootloader-hammerhead-hhz12h.img
target reported max download size of 1073741824 bytes
sending 'bootloader' (3119 KB)...
FAILED (data transfer failure (Unknown error))
finished. total time: 0.073s
So again at a dead end.
Any ideas?
