Hi,
First let me say I’m not a modder and this is a new laptop. I’m not inclined to open it up to do any hardware mods. 8th gen i7.

I was installing the updates from the Lenovo site 2 days ago, and suddenly after the IME firmware update to 11.8, it wouldn’t boot. I think I might have interrupted the update. So I finally figured out that if I disable PTT in the BiOS, it will boot normally to Windows, and vice versa. With PTT enabled, I cannot boot from any device, even with legacy mode and secure boot off. I don’t even know if all this is related. It’s not something I would normally get into.

I had done the bios update 3-4 updates before the IME update. In the 2 days I’ve been trying to fix this I downgraded the bios, which had the same results. Upgraded the bios with same results. Reinstalled Windows from a recovery usb. I can’t reinstall Windows from a regular iso because it would not find any of the 3 partitions.

I tried a newer version or the IME firmware from this site, and drivers and manually running the command from an elevated command prompt to install the firmware. One of the error code was 8743 I think. I’m going from memory.

Also TPM 2.0 is in device manager but I can’t load a driver to it. I don’t see IME in device manager.

Is there anything I can do ? Can I flash the firmware from DOS? Should I rma the laptop? Should I live without IME/PTT?

Thanks, please advise me and know I’m not in the field.

thanks, for your reply. I was hoping you'd come to this thread!

I've been fooling around reloading BIOS (new and prior) and have loaded drivers and now see it in device manager with exclamation point. I can't update the driver or firmware or boot with PTT still.

is there really no way to recover?
I like this laptop a lot and would like a way to keep it. it was a super black Friday deal and there is no way to exchange it. if I were able to get them to send me a replacement motherboard, would that fix it? (then I could update the driver/firmware)

Thank you!
The model is lenovo yoga 720-13IKB, 81C3.
I just got a screwdriver and opened it but I didn’t see a battery. If you can tell me where it is, I’ll pull it. In the meantime, I’ll try to run the commands you said.

Here is a picture of the inside.

ok, I think I've got the info you requested.

thank you!

I must be lucky...

:)

I ran fptw64 since I am in a 64 bit windows, ran it from CMD with Admin privileges

thank you.

I’m so excited!!
I’m not home right now but will try asap!

Thanks again!!!!!

Looks like my luck ran dry

Error 451: The host CPU does not have write access to the target flash area. To enable write access for this operation you must modify the descriptor settings to give host access to this region.
FPT Operation Failed.

I’m sorry I don’t know how to do this.
I may a flashable usb drive using Rufus and freedos. I put the efi folder in that. I tried running the command from c: and from the sub folders. I also reformatted the flash drive and just put efi folder on it. No gusto.

:/

Looks like I’ll either have to get a replacement or refund from Lenovo. Attached are screenshots.

Thank you for your help! You are incredibly kind to help so many people on this site.

Best wishes for the holidays and new year.
