Create a folder on your Pc and unzip the fastboot and 2.5.0.9 files into it. You will then need to use a Dos prompt so you will need to acces the file in dos. Its easier if you extract everything to the root of a drive which saves finding folders in dos..
So presuming you extracted everything to the c: drive and are using the modaco 2.2 alpha the command would be -
fastboot-windows flash recovery recovery-clockwork-2.5.0.9-modaco-r2-blade.img
This will install the clockworkmod onto the phone....
Navigation in the recovery image as follows:
* Volume Up / Down to move between options
* Home key to select an option
* Back key to go back
Step by step install instructions
* Download 2.5.0/9 r2 ClockworkMod Recovery for ZTE Blade - DOWNLOAD (ROMraid Load Balancing) - MD5: d7664757ec3d4862cc408b7304e4df8f
* Download fastboot if you do not have it already.
* Turn off your phone and take out the battery. Unplug the phone from the PC / charger.
* Replace the battery and turn the phone back on with 'volume up' held. The device will stay at the 'green android' screen.
* Plug the phone into the PC.
* Extract the fastboot zip file.
* From a command prompt (at the directory containing these new files!) run 'fastboot-windows flash recovery recovery-clockwork-2.5.0.9-modaco-r2-blade.img' (subsituting 'fastboot-mac' or 'sudo fastboot-linux' as required)
* When this finishes, from the command prompt run 'fastboot-windows reboot' (again substituting 'fastboot-mac' or 'sudo fastboot-linux' as required)
