Hello everyone!
I've messed up. After flashing a custom BIOS, I modified a BIOS Graphics Memory option, and since then my laptop has not booted (no logo, no screen, no nothing).
On normal boots, the laptop will start, stay on for 5 seconds, and shutdown. It only does this when memory is in the machine (I assume it's trying to allocate more memory than is available, I can't say).
Anyway, I've attempted BIOS recovery several times, with guides such as this one (bios-mods.com/bios-recovery/insyde-bios-recovery/). Specifically, here's what I've tried:
Here's all the file names I've tried: i.imgur.com/VeMb7NE.png
Any suggestions? Is there something I'm missing? There's also a thread here that suggests examine the platform.ini file, but none of the strings "model=" or "platform=" were found.
Thanks in advance.

Anyway, I've attempted BIOS recovery several times, with guides such as this one (bios-mods.com/bios-recovery/insyde-bios-recovery/). Specifically, here's what I've tried:
- Downloaded latest BIOS from Lenovo's site (support.lenovo.com/us/en/downloads/ds036474). Extracted "BIOS Update.exe" using 7-zip.
- Downloaded the Phoenix Tool (forums.mydigitallife.info/threads/13194-Tool-to-Insert-Replace-SLIC-in-Phoenix-Insyde-Dell-EFI-BIOSes), ran it on the WinVIWGP203.ROM file from the extracted exe. The suggested file name is "VIWGPX64.F?"
- Copied and renamed the original WinVIWGP203.ROM file to VIWGPX64.FD.
- Format USB drive (in my case, 4 GB, FAT32), copied the new .FD file to it's root.
- Disconnected battery, power cable, etc., from laptop.
- Plug USB in (all ports tried).
- Held down FN+B (FB+R also works on this machine). Plug in AC Adapter, power on.
- LEDs light up, let go of FN+B. Fan spins heavily. LEDs lit are white and orange.
- USB drive flashes twice or so immediately after pressing of power button.
- 30+ minutes, no change. No beeps, no flashes, no USB activity, nothing.
