This is awesome, i´ve tried all of the possible solutions and non one was useful until i saw your reply. I want to say thank you Yogz, did exactly what you just postd here and now i have my BIOS unlocked.
My BIOS was A36 and the ending of my tag was 1F5A, and whe i was trying to get my unlock number there wasnt any one, so i downgraded my version and then when i tryied to get my password it did appeared.
So then again, thank you so much.
BTW i was trying to unlock my BIOS to disable eSATA-Ports, i dont know why but those ports were the cause of lag on audio and videoComment

Hi everyone
I noticed on the Xgpro software the BIOS backup files have extra bytes at the end when reading some chips, this is because the Xgpro software also reads the OTP region of those flash chips, and by default will append that region to the saved file
Programmer models: XGecu TL866II Plus / T48 / T56 / T76
Example: GD25LQ128D (1.8V), IC size is listed as 0x1000000 Bytes (16777216 bytes) + 0xC00 bytes, those extra 0xC00 bytes will be appended to the end of the saved file by default, resulting in a file size of 16780288 bytes
There's also an extra OTP Secu.R... -
My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS
Hello everyone,
I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.
This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.
I have opened the laptop and identified the main BIOS chip... -
Hello,
I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.
However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)... -
Hi all,
My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
The charging red LED lights up, but the charging screen doesn't show any indication.
When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
(I've tried removing the battery and resetting the device, but the issue persists.)
