by m1ch43lzmHi 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

by to5it0Need 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...2 Photos-

by Flasman90I have a 2020 Macbook Pro A2289 and after many attempts managed to get it into DFU mode, using my older 2017 A1706 Macbook Pro (Running Ventura 13.7.8). However, when attempting 'Restore', it fails at step 4 of 4, showing the following error:
- "The operation couldn’t be completed. (AMRestoreErrorDomain error -1 - Failed to handle message type StatusMsg (Generic error)) [AMRestoreErrorDomain – 0xA (10)]
- "The system cannot be restored on this device. Failed to create new state machine for restore [com.apple.MobileDevice.MobileRestore - 0xFB1 (4017)]
