Re: T2 Chip Programmer Tool
I only took the decision to close the thread. It was deleted on OP's request.
It was a complete mess anyway. If you want to share actually useful and correct information, please do so, that's what everyone is here for.
But as I said already, if you have nothing to share then don't. There's already way too much noise and misinformation out there, and we do not need any fake promises and even less of baiting people into commercial affairs.OpenBoardView — https://github.com/OpenBoardView/OpenBoardViewComment

Re: T2 Chip Programmer Tool
Thanks so much, I wasn't aware of that method. Now I just have to work out how to access all 32 pages. Using that method the only two that I can access are pgs 28 and 31.

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
Hi,
had T490 with faulty bios chip. Bought chip out of ebay and soldered on. Laptop starts and works however serial numbers of laptop and motherboard do not match.
I have updated laptop model number.
1) I did not find the way to update laptop serial number - I have this one.
2) I dont know where to get my motherboard serial number and how to update it. Is it somewhere physically on the mainboard? How do I update it?
Hope to find someone to help me with this as I am hitting dead end at the moment.
Many thanks

Adding chip support is quite easy,there`s even some instructions included with NeoProgrammer,although its not obvious where they are
and once you do find them there`s a few crucial steps missing.
Extract chiplist.zip to a folder,the instructions are in Import_EN.txt and in Import.xml .Its the xml file where we add the new chip.
Open Import.xml with notepad or any other text editor.In this example i`m adding a Macronix MX77L25650F SPI_NOR chip.
After adding the chip save the xml file and copy it to the root directory of the... -
Common SPI bios chip programming Questions and Answers
----------------------------------------------------------
Q: I have a bios request,i can`t post my backup as i can`t read from the chip.
A: If you can`t read from it how do you expect to write to it ?.
Q: Why is my bios chip unreadable ?.
A: The programmer is faulty or has a worn or broken zif socket.
The USB cable is frayed,connector pins worn or some other physical damage.
Not enough amperage or voltage to power the programmer properly.

Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...
