I have quite long time didn't flash phone anymore. May i check the steps with you?
1. Get the unlock code from Huawei
2. Install TWRP
3. Root the phone
4. Flash the rom from 1.0 > 1.1 > 1.1b
5. OTA to 2.0
Btw, where to enter the unlock code?

all your steps is correct.
flash the original rom first. let it boot up + configure your gmail acc etc. when that part done, proceed to 1.1 - let it boot up. When it's done, proceed to 1.1b.
to get the OTA 2.0, you need to launch OTA Updater. Then let it will prompt for your action to proceed with the 2.0 version.
* unlock code? That will be generated by Huawei website. when you entered all your serial number + IMEI = then you will get the code from them. I would advise you to write it down or get a print screen of that code (just incase..)
The lock code will be needed when you use Multi-Tool to root it
Good luck!
