X230 BIOS downgrade from 2.77 to 2.6

Easy downgrade, no hardware mod and just typing some easy command in command prompt. The stupid Lenovo tries to prevent you guys to downgrade BIOS.

1. Download BIOS update file ver2.6 (.exe) from Lenovo (https://support.lenovo.com/us/en/downloads/ds029187-bios-update-utility-bootable-cd-for-windows-10-64-bit-81-8-7-32-bit-64-bit-xp-thinkpad-x230-x230i)
2. Execute the downloaded file.
3. You will get an error saying like 'system number does not match blah blah blah'. Just exit the program.
4. Go to C:\DRIVERS\FLASH\g2uj17us just created
5. Go to command prompt, winflash64.exe /sd /file C:\DRIVERS\FLASH\g2uj17us\G2ETA0WW\$01D3000.FL1
6. The computer will reboot and flash the version you want accordingly.

You have to use BIOS ver2.6 to remove the whitelist checking.

我的(新) notebook Lenovo X230

話說小弟終於有部新 notebook，我是從 Craigslist 尋寶回來的。

小弟離鄉別井後，一直沒有自己擁有一部專屬電腦，只是常常流動的使用老婆的 HP 發燒 notebook(佢成日好鬼熱，個風扇成日都好似開 turbo 咁都散唔到熱。仲有就佢個入風位做到超差，你平放張枱度佢都會自動 overheat 到自動關機，你話我起唔起火，所以我成日都同人講千其唔好買 HP notebook，買 dell 好過)，或者係姐夫家的 chromebook 或 dell。當然，我老婆部 HP 係平機款，但我都係覺得唔應該會過熱，枉佢仲係 HP 產品。

講翻我部新 notebook，佢極度新淨，最終賣 USD$400。Config. 如下：
Intel i5 3320M 2.6GHz
4GB ram + 4GB ram (upgraded by seller)
Samsung SSD 840 EVO 250GB (upgraded by seller)
USB 3.0
Fingerprint reader
Bluetooth 4.0
Webcam
HD4000 display
12.5" 1366x768 monitor
Ultrabay Series 3 docking with DVD-RW
6 Cells battery
another 6 cells spare battery
Notebook bag

部機仲有 3 個月保養！我知道呢部機唔係新機，佢仲係兩年前o既機款。但係呢個 config 對我嚟我好似真係夠用，同埋，佢已經係 SSD，真係開關機真係爽爆炸，同埋，個指模開機真係好過癮，辨認率十分高，直頭一揭起個 mon. 就可以 scan fingerprint 開機，入到 windows 仲可以自動 login 埋添。我用咗兩個多星期，真係無咩投訴。速度一流，又唔熱，又暢順，又無咩嘈音，又輕，仲有我好 like o既小紅點。唯一投訴就係佢個 keyboard 係無 backlight 的。又可以重拾 IBM Lenovo X series 啲情懷，真係好開心。

唔知，呢部機我會用到幾多年呢？
