this is what mrgadgetuk did
Delete all system files from your SD Card: .android_secure; Android; data etc from your previous installation. Create a txt file and name it mtdpartmap and type mtd 180 25 inside and save it. (The other 2 files you will need to place onto your SD Card (bravo-recovery-v1.5.3-CustomMTD.zip & bravo-boot-v1.5.3-CustomMTD.zip) can be obtained from here http://forum.xda-developers.com/show....php?t=1233340
Place the mtdpartmap file onto the root of your SD Card and put it back into your phone. With your Wildfire Buzz off, hold down the VOL DOWN button and POWER button simaltaneously until the HBOOT screen is visible. Highlight CLEAR STORAGE, press the POWER button and then VOL UP. It will reboot after 5 seconds. When it does, immediately remove the battery and put it back on again.
VOL DOWN & POWER button again, and this time enter RECOVERY by pressing the POWER BUTTON again. Format sd-ext; cache; data; system and boot (inside MOUNTS & STORAGE). Then, go into ADVANCED and WIPE DALVIK CACHE. Click on INSTALL ZIP FROM SDC and flash bravo-recovery-v1.5.3-CustomMTD.zip and then format SYSTEM' CACHE & DATA again.
After this, DO NOT REBOOT THE PHONE, go into ADVANCED and REBOOT RECOVERY. Now, you can flash 'Non-official CyanogenMod 9 RC-0' (SHOULD TAKE 90 SECONDS). After you've flashed that, immediately flash bravo-boot-v1.5.3-CustomMTD.zip. Then, flash gapps_ics_4.0.3 v11 (SHOULD TAKE AROUND 50 SECONDS).
NOW, you can reboot your phone....
It will take 8 mins 30 secs before it finishes its stuff.. then follow the on screen instructions..
175 MB free storage after installation, not 200+ sorry. But still good...
