I’m currently working with an Adesto AT45DB081D SSU chip that I’m trying to read and write using a CH341A programmer. As many of you know, this specific DataFlash device is not natively supported by most CH341A software, which complicates the process.
I would like to ask if anyone here has successfully managed to add this chip definition to AsProgrammer (or any other CH341A-compatible software) and if so, how they handled the custom read/write commands. Any guidance or working configuration would be greatly appreciated.
Just to clarify my situation:
I had a serious issue with my iOS BIOS chip, because some so-called “technicians” injected incorrect data into it and didn’t make a proper backup of my original BIOS. Because of this, I spent an entire day researching and was able to gather a lot of the required information.
As I mentioned in a previous post, I needed to reconstruct the DMI region in order to restore the original system data. However, I don’t know exactly how the DMI region should be rebuilt.
For reference, I’m attaching the following BIOS files:
Attached BIOS files:- FHCN78WWD Decrypted.bin – This file contains the BIOS already flashed with the data I currently have. This is the one I plan to use, as it reflects the state I currently have.
- FHCN78WWD Encrypted.bin – This file is the encrypted BIOS, the one that is read when the computer is powered on. I hope it is correct.
- Backup BIOS.bin – This is a copy of the computer after it was handled by the so-called technicians. The data found in this file was injected and is obviously not correct.
Any help from those of you with experience in this area would be greatly appreciated.Comment

Model: Lenovo IdeaPad 3 14ADA05 81W0
S/N: PF2BZS7D
I was having issues with this particular laptop where the NVME SSD would disappear and would not detect unless I took it out and reconnected it, then it would detect for only for a minute then disappear from BIOS. I figured updating the BIOS was worth a try so I booted into my HBCD USB and downloaded the latest BIOS file for that exact model. I ran the executable and everything went smooth, it beeped and then when it restarted, now it won't post, just black screen with fan spinning.
I already have a CH341A programmer... -
