  1. I don't know. I think that may be seller reflash M2000M to M2200M with hardware SPI programmer.
  2. Well, try use this Nvflash version: https://www.sendspace.com/file/ojzz04
  3. Try use command without --index=0 Just type nvflash -6 GM206.ROM
  4. Hi! Post here your stock vbios, I'll take a look. You can get vbios using GPU-Z utility, just mouse click on small icon with arrow, choice "Save to file".
  5. Hi! Device Id: 10DE - 1430 it is Quadro M2000 (GM206GL) Device Id: 10DE - 1436 it is Quadro M2200 Mobile (GM206GLM) It's different GPU. I think that you can flash this vbios: https://www.techpowerup.com/vgabios/205283/dell-quadrom2200-4096-161024
  6. Hi! Unlocked bios does not help with refresh rate. It's hardware Lenovo design for this laptop model.
  7. If you laptop can start, booting in Windows, but with black/blank display, then it means that you can reset the BIOS to default settings blindly. Try completely disable laptop with press and hold Power/Start button. Then: 1. Press and hold F2 key 2. Turn laptop on. ( still hold F2 key) 3. Wait 5-7 sec, then release F2 key. 3. Press F9, then press Enter key.4. Press F10, then press Enter key.5. The laptop restarts and now all should be good.  If you laptop can't start, and can't boot in Windows, then use this method: Pull out all RAM modules, enable laptop without all RAM modules. Then disable laptop. Then temporarily insert only one different RAM module (with another memory size or different manufacturer), and start laptop. After these steps bios should be reset to default settings.
