ROG ally Z1 Extreme bios ok?

[ongobongo]

Hello,
I'm fighting with an rog ally that i bought broken and which will not start. I found that the ec chip was shorting out so i replaced it with a new and empty one, short's gone and values look good. unfortunately, the ec chip doesn't reprogramm itself although - according to experience from others I've checked with - it should rewrite itself. WHen i attach power, both ec-chip and bios get power supply. to dig further i decided to read bios, maybe there is some corruption going on in there. Bios chip is a Winbond 74m25jweiq, neoprogrammer/ch314b identifies it as W25Q256JW and reads it completly.
Could someone with knowledge do me a favor and check the image if it is fine or if there is something corrupted/suspicious?
Thanks in advance

Hi mate did flashing the bios solve this issue? I too have changed ex chip, rog ally works off battery power but wont charge was just wandering if up to date bios flash’s the ite chip and solves issue, cheers bud.

No in my case the bios update didn't help at all.
If you have it working on battery just update the bios normally than all subsystems should get updates if available

Can’t update the bios because when i try to wipe the ally and do a fresh install of everything it asks me to plug in the usb c charger to continue and it doesn’t pick it up so im stuck now, installed windows 11 from pc and copied it to ssd still same thing, looks like a i need the ite chip to be picking up the usbc being plugged in before i can do anything.

And you are sure the port is physically ok? I doubt it is the ec chip, when the ally itself is working. I'd think it's something with the power management circuit, check the area around the intersil chip (if i remember correctyl, it's the ISL9420)

have you tested the port further by attaching USB-devices?
