This is the first time I tried to install a custom rom. Please be gentle.

Device: Huawei Y300 (Bootloader unlocked and rooted)
TWRP Version: 2.5.0.1
Custom rom: cm-11-20140510-NIGHTLY-u8833.zip (found here)

I mindlessly tried to flash cyanogenmod 11 (kitkat) on my Huawei Y300. Here was the last steps I did:
  1. copied rom and gapps zip files on phone root
  2. restarted phone in fastboot mode
  3. on ADB, ran
    Code:
    fastboot flash boot path\to\boot.img
    (everything seem to be working fine)
  4. ran
    Code:
    fastboot reboot
    (phone rebooted in TWRP)
  5. Tried to install cm-11-20140510-NIGHTLY-u8833.zip rom file (installation failed)

From what I read, the version of my twrp is not compatible with kitkat? Now i believe I bricked my phone because I forgot to create a backup of the stock rom.

Questions:
Is the stock rom still somehow there, hiding in my phone memory?
Is it possible to "undo"
Code:
fastboot flash boot path\to\boot.img
so that the "original" boot.img is used by my phone when I try to reboot it?

I am currently downloading Android SDK with a plan to upgrade my twrp for kitkat compatibility. I hope this will let me install cyanogenmod kitkat on my huawei. But I am not sure if I will succeed. If I still fail, can you guys tell me what other options I have to save my phone?

Thanks

Edit: problem solved.
I learned how to properly flash/upgrade twrp via fastboot.. Retried installing rom with twrp 2.7 and it was successful.
