soft brick or HW failure

So I was doing my normal morning routines sitting at table and checking weather quickly then suddenly it just stopped showing a screen. This set of events is exactly how my 5z died... the 6 I could at least hard-reboot

So I went to desperately try to fix to recover at least my authentication codes. What happens is that I can get it started but then dies at random points. Sometimes 5 seconds and other 1 minute. Eventually it just stopped responding to anything. The whole time I had to force reboot with pwr+vol down.

Problem at this point:

Getting a charging light or screen was not happening, no boot screen, no recovery mode.

At some random point I started to get a charging screen, at 92% battery after many,many pwr+vol_down. Then later on started to get into recovery. I did a full wipe in hopes it was software but that did nothing. I downloaded the latest image WW-17.1810.2005.153 for US variant I01_WDX but still nothing (which did a full install just fine without a lockup). Once I got back into a charging screen I let it go to 100% -- mostly because I was at it for a few hours and wanted lunch.

At this point it did boot but was very in-stable. First boot got past setting up wifi. Second got past setting google account. Last I was starting to sync all apps and such from google and all looked really promising then died -- back to the very beginning of not getting any lights/etc.

It almost seems like some kind of power delivery problem or some kind of thermal because when it's in this state i found that being in front of the AC and getting this cold makes it "work" - in that from a dead state I can get it to start showing charging screen (which is now 100%). It's hard to say thermal because it gets warm when it's working and being used when not crashing...


Some boots the screen will show asus logo, then zenfone and screen will turn off, but still show zenfone booting, then shortly after will reboot.

I can get a red led but no screen with power in + pwr+vol_down - never gets out...

Phone seems "stable" when in lock screen for first time, after login it dies randomly

I need help, I really want this to be stable again. Is there anyway I can fully load the firmware/boot images manually or figure out why it's crashing/locking?
