Bricked (dead flash??) Nexus 5. Am I missing any recovery options?



I got the infamous broken power button that made the Nexus 5 restart endlessly.
I managed to fix it by bashing the phone on the button as per the many guides online and the power button now works fine.

However, it seems either the phone bricked or the flash memory died as the following happens:
- Stuck on endlessly trying to boot Android 6.0 (stuck on boot animation)
- Takes 10 minutes to boot into TWRP (gets stuck on blue screen). When it boots, it reads all storage as 0MB and there are errors trying to mount ALL of the partitions (data, system, cache, etc)
- Phone boots to fastboot. When trying to flash anything to it (I was trying factory 6.0 images manually), I get FAILED: (remote: flash write failure)
- Locking the bootloader from the fastboot menu works, however, when I restart the phone it is unlocked again
- Phone seems to be able to read data (it tried booting android, the TWRP recovery works) but it can't write ANYTHING to it
- I tried both fastboot erase and fastboot format. It fails to do both of these.
- I had the idea to next try and boot it into LG Download mode to flash it to stock using the LG Download tool. I cannot boot into Download mode, however, as pressing Volume_up + plugging phone into PC results in the battery icon for charging. This is the same behavior with my other Nexus 5 (running 6.0) I have.
How can I boot into Download mode on Android 6.0?

Possible the flash storage chip is fried? If so...why can I read fine from it?
It's almost as if it went into write-protect mode or wore out it's write-cycles of the flash.:confused:

It is out of warranty. Do I have any options short of a new phone?
