Hi there, I have a ThinkPad X1C6 which I got cheap from a friend as I've mentioned before if you decide on checking my profile, but it has issues, including both the bios and thunderbolt firmware bricked. So far, I got a 20KG bios from indiafix, however, I still haven't figured out how to fix the thunderbolt firmware issue ( I feel like mentioning that I've never worked with FL1 and FL2 files or with any Lenovo product and I'd wish to not brick something beyond repair. ). Can someone with this same model of laptop give me a thunderbolt dump of the chip (Winbond W25Q80 ONLY) and compare my dump...08-24-2025, 03:08 AM

Hi everyone.
I got this Lenovo ThinkPad X1 Fold Gen 1 20RL000VUK from a customer that stated that his son was playing with BIOS settings and now it wont turn on. I guess the customer son was trying to update BIOS via windows and it shutdown while updating and it bricked this device.
I've tried to find the BIOS firmware everywhere and nothing is available.
Can anyone here help me to check if the firmware is corrupted and has a bios firmware for this model, please?
It does not turn on, but when plug the charger the fan goes full speed and power button blinks 3 times. Sometimes...
