I repeat one last time, lenovo password is not in the BIOS. You have two options
- IO programming MEC or Buy an outside patch service.
Please understand and remember the problem.

Hi,
I have accidantaly erased my yoga 460 bios chip without backup them.
I have tried several files and no boot, no display, only fan spin loud.
Board is LCL-1 14283-2
Its a yoga 460 but don't know exact type number.
Can you help?
2 files found here not working. Now trying with r05uj11ww.bin
Comapred files, they are identical when reread so programmer is okay. I used pomona clip so connection is ok.

Laptop worked before erase. Booted to bios with password and computrace. After ereased no boot, no display. Only fan spin high and auto on if battery connected. Changed cmos, charged battery to 100%
I'm sure its chip content problem not hardware!! HELP!! :)

Yes but already unlocked. Weeks left from that post. I do the unlock for myself. I have all the required equipments.
My question is only why TPM stuck in MFG MODE after I flash with clear me .bin file?? Before flash TPM works great. Can change mode in bios. After flash clear me tpm stucks in MFG MODE

How does MFG affect the working process of the computer?
how to you unlock, I think this is the problem.
Note I do not answer further and support if you do not buy unlocking service from us

Please understand this problem not caused by unlocking. I have same problem with not locked laptop also which have ME area damaged but don't have bios lock or password or anything. Fully unlocked, just ME region damaged. But TPM can change in bios. You can set to inactive, active, disabled. After flash clear me region .bin file TPM mode cannot change anymore, stuck in MFG MODE!! This was tested on X240, Yoga S1, T440, T450, Yoga 460 both locked or factory unlocked pass free models. So not caused by my patch unlock.
