Yes. i have done flashing CWM in recovery. and then i just follow the first page step by step guide..... as below:
1. After flashing CWM you get ready your firmware you just downloaded.
2. Plug in USB and enable Mass Storage.
3. Put it inside your EXTERNAL SD card (Not INTERNAL)
4. After it's done, turn off your phone.
5. Turn it on while pressing power button + volume down button until the 'ANDROID' word shows.
*Hands off and scroll through the menu with volume up/down button.
*Power button is like 'enter' in CWM.
6. Scroll down and choose 'wipe data/factory reset'.
7. Optional Step (?) Choose 'advanced' and choose 'wipe dalvid cache'
8. After wiping it you choose 'install zip from sdcard'
9. Then choose 'choose zip from sdcard'
10. Choose the firmware zip and confirm.
after i can't update the new firm... you advised me to reflash Clockwork MOD, but all my data in phone all gone... so i go to market to download the Rom manager again and flashing CWM in recovery again.... then continue the step by step..but still shown:
Finding update package....
Opening update package...
installing update..
Installation aborted.g
What is my next step...?? Thanks..
Flashing clockwork mod recovery won't wipe your data.
You did something wrong I think.
You haven't say which rom you're flashing too.
