Hi, thanks for these instructions. Slight problem...

From Section 6 (downgrading from ICS to vodafone GB), near the top:

• When prompted reboot your phone, By holding the Power Button down and selecting "Reboot" (I presume you mean "restart")
  
• The device will then begin a reboot loop this will go through many different stages and can take up to 5 minutes.
  
  At this stage, the phone just shows the Huawei logo, then goes into the CWM-based recovery screen. It then says "E:Invalid command argument" - Any advice?

I came here to ask the exact same question. Same issue exactly.

Why am I getting a panicky feeling about this...? Have I screwed the pooch?

Try pulling the battery for 30 seconds and then try restarting the phone. I've known this error to happen at times and a battery pull to cure it.

Continue following the guide, specifically the steps involving CWM.

Tried that - in fact, its the only way to break the cycle.

Can't try that - locked in a vicious "OFF < > CWM screen" loop. But thanks for the attempt.

Is this the only possible solution?

As you can get in to CWM, have you tried flashing a new ROM?

[droiddruid]

From the recovery menu (Volume Buttons go up and down and Home is Select and Back is Back.) Select the following and in this order.
Wipe Cache Partition > Yes
Wipe Data / Factory Reset > Yes
Advanced > Wipe Battery Stats > Yes
Advanced > Wipe Dalvik Cache > Yes
Advanced > Fix Permissions > Yes
Reboot > Yes
This will then reboot your phone (On some ROM's it many not boot now but do not worry)
Download and extract the contents of an official stock GB update. [For the official Vodafone Online Upgrade to ICS choose the B885 or B892 firmware.]

Hmm, I'm having trouble resetting the IEMI to 0.

I've followed the guide several times to (downgrading from ICS to GB) and its still showing the original IEMI. Any suggestions?

[0066ad]

This downgrade should be updated, without all this middle update app and restoring imei, alot off people are
having problems with it.

There is none of this needed, it is very confusing.

The force downgrade is much easier no middle package and no imei hack,
and only takes two minutes

[baluepauk]

Worth a try as it's less hassle but in some circumstances it will hang a third of the way through even with the middle file. If this happens then the zero imei method might be necessary.

[0066ad]

It worked for me with no problems, now back on atomicmod with overclock
my phone has never been better. Thanks tcpaulh and also tillaz for the great
rom it's a pity, it's is not in development anymore in my opinion it's the best
rom for this phone at the moment
