I presume you're referring to the B952 update.app?

If so you can still get it direct from Huawei:

Sorry - I don't really understand your question.

If you are asking if you need the stock B952 as well as a stock ROM then the answer is no.

But you need stock (e.g. B952) in order to do an official bootloader unlock.

No.

To unlock you need to revert to custom ICS temporarily as explained in the tutorial.

Then once you have unlocked the bootloader officially you can root, install CWM and install your custom ROM.

Was on custom Gingerbread ROM.

Made sure to have my IMEI normal, matching what is under the battery*

Updated to ICS via official V100R001C02B936 update.app.

Unlocked bootloader via the official Huawei method.

Ordered SIM unlock code.

Unlocked SIM-lock the following day.

Fastboot to install CWM. CWM to install custom ICS ROM.

All Good!

 

Thanks, OP!

 

*if already on ICS with bootloader officially unlocked and CWM installed, zeroing/altering one's IMEI is just asking for trouble.

Really? I cant even be bothered to condem it, so Ill just stick with, that's not the best idea - if you have reboots, try unlocking with mine, as that seems to solve that problem.

You mean you can't extract the contents of the split zip?

If so then I think that a single zip of the B952 update.app should be available elsewhere.
