Thinkpad X13 Gen 3 Not Charging via Thunderbolt after an update. Ran out of battery and stays at 5V Fan spins for a second when it switches on, but then the power button blinks 2 times and goes off. Dont have a fully charged battery to charge and flash over Windows. Although the TBT Utility doesn't have Gen 3 version, only gen1.
Based on this feedback - https://www.badcaps.net/forum/showthread.php?t=82558&highlight=X13 I have tried
- I managed to extract a TBT.bin from Gen 1 version, but I don't think its compatible, as it's not even moving to 20V as before, but stays at 5V only - https://support.lenovo.com/au/en/dow...n-1-t14s-gen-1
- Padded with FF until end to fill 16MB bin and still no success in loading
- Flash all FF and tried to boot up, but it still stays at 5V
- Tried holding the RST button with no battery installed as per https://www.badcaps.net/forum/showpo...70&postcount=3
Does anybody have gen3 firmware for the TBT or know if Gen1 is compatible and if I am doing something wrong?
I think UB1 rom, is the TBT?

While this one is the SPI Rom I think?

Found the bord layout for this model but no schematic so cant confirm.
Lenovo ThinkPad X13 Gen 2 NM-D361 BoardView PDF is close by layout, but cant identify the second BIOS for the TBT. JBIOS looks same as main bios W25Q256JVEIQ
