Apologies for the delay in updates, but development has finally resumed. I've resolved the NVRAM reset issue. In addition to correctly resetting the header, I discovered a bug introduced in version 1.1.4 where the NVRAM store type (VSS, SVS) was not properly assigned. This has now been fixed.
Additionally, I'm introducing a new T2ROM window, where you'll be able to view the iBoot version, serial number, and export/transfer the Scfg serial store (Intel only, image attached).
Looking ahead, after the release of version 1.2, the next update will focus on separating EFI and T2-related tools. A new startup window will be introduced to detect the ROM type via drag-and-drop functionality, etc. However, for the time being, the T2 UI will be open over the main window as a tool window, as I'm working with limited time per release cycle.
More changes are noted in the dev changelog, which will change before release.

Okay, never mind. I suppose a little delay wouldn't hurt to make it proper. New startup window added, multiple ROM windows enabled. More coming.

Welcome to the forum! Glad you developed something like this. This would come in handy for MDM removals on T2 machines. I do this by hand for most of the MDM locks of old devices. This is truly remarkable.sigpic

Version 1.1.5 released, bringing an important bugfix when resetting NVRAM. I've had to pull the dev branch down for now whilst I get everything in order.

The version 1.2.0 development branch is back up on github, there's a list of changes in the changelog which is mostly complete, there are also images of the UI redesign. And thanks for the information, I'll add an option to change the serial in the ROM then.
I don't recommend compiling and using anything in dev as it's unfinished and unstable.

Unfortunately access to the T2ROM by any means other than removing it is out of my scope, I don't even think it's possible. However, I put some information here on how to dump the SPIROM very inexpensively:

I can't figure out how to change the serial number! Or is this program not able to do this?Comment

Mostly correct. T2 Macs still have an EFI, but it's in the NAND and inaccessible. The program can edit serial for Intel based T2 SOCROM, and EFIROM => Click "Patch" and select "Change Serial Number", the application will then replace the SSN and allow you to save the patched firmware.Comment

In order to bypass an MDM it would be ran with software, however when trying to REMOVE the MDM lock permanently, one would need to change the serial to the device. If you can change the serial number on the device without the need to desolder the chip that retains the information of the board such as EFI lock/FIRMWARE LOCK, Serial number of the board then that would be pretty awesome. But in order to remove the MDM lock on T2 machines one has to desolder the SOCROM chip next to the T2 chip. Reprogram with ASPROGRAMMER, and then change the serial with WinHex. Find the serial, DO NOT change any of the code but the serial so it can still normally boot. That is how its done.sigpic

Is there a way to change the CPU multiplier through editing the laptop's BIOS. I have a Latitude 7300 using Intel core I7-8665U CPU which has default multiplier settings between x4.0-x48.0. The problem with the device is that as soon as Windows boots up, the processor temperature is always high (usually in the range of 97-100 degrees Celsius), the multiplier is in the range of x46.0 - x48.0 even though no applications enabled. On a desktop we can change many things related to core voltage, multiplier or base frequency. but on laptop models using U suffix processors this is not available. I would...07-22-2024, 07:57 PM

Copying DMI information from an old bios to a new one is difficult for some members, often they have no experience with a hex editor,or some that have tried find it too hard.There is an option to make things easier for those members so that they don`t need to post their own bios backup for the DMI copying.
Experienced bios modding members can help by posting in other threads the DMI offsets,macro script generated by the software and a download link to the software at softpedia mentioned in this guide,or post your macros in the comments here with a link to the bios request thread .... -

Hello,
I have a Lenovo Flex-14IWL here that I believe might be suffering from a corrupt BIOS. The device tries to power on, but black screen and no fan spin. The power LED then quickly turns off. I admit I am not 100% certain it's corrupt BIOS, but this is something relatively easy that I can rule out before I begin diagnosing board-level hardware problems. So far, I have:
1. I have saved the original (possibly corrupt) BIOS from the chip using a programmer. This file is 16,384KB in size and is in .BIN format.
2. I have extracted the BIOS image from the Lenovo...
