Thanks what partition to choose for flash

All 3 chip models give the same results, so you can choose any one.

Hi Guys,

Have a 7050 micro with "Unable to detect TPM", won't boot from anything, no option to re-flash BIOS.

Not sure if this is BIOS related, all searching says maybe not, but can anyone please take a look?

Going into BIOS, TPM isn't listed at all under security. PCB looks fine no signs of damage/spill.

Attached is dump - Service Tag 4DXP9M2.

Thanks!

Haven't tried this yet as I busted a pin off the chip desoldering it from my programmer. Have ordered another and will let you know (if) it ever arrives from AliExpress.

Hi,

Try your file from post #10 and see if the device will works and give you an error for TPM, or it will not work at all.
