If you have join me installed the driver step can be skipped.
Anyway I decided to edit this thread to make it easier to read, and more newbie friendly.
To have the phone updated you need:
A working XP32 machine and the drivers installed (either from join me sw or the ones included on the
one click updater package)
Then :
#1 Download, decompress and install the
one click updater (archive's PW is
zte_u960)
#2 replace the file
RF.ZTE with the one I've uploaded
here
the file location is usually
C:\Program Files\ZTE\DL_U960_CMCC_CHN_EU\version\) but the location could be slightly different depending on Windows' language and drive installation.
#3 Start the update process using the previously installed updater
#4 If the process went trough correctly (dial
*983*154# to check your actual version) and the phone rebooted correctly, you can turn it off and reboot it in recovery mode (turn it ON keeping the power button and Volume UP depressed) and apply the
update package I prepared to get the phone
rooted and
gapps installed in one step.
#5 you can (optionally) flash also one of
Catty's mod kernels to get the 1.4Ghz overclock and init.d function (see the linked post), is better to wipe the phone after this step to avoid market problems.
#6 If, after the flashing process, the USB function of the phone doesn't work as expected (E.g., no USB storage available), you may need to use the
set mode utility to switch it back to its original behavior. (select the option on the left and confirm with the button on the left)

replaced the root + gapps market package that had some problems with the market with the V2 (root + gapps/playstore), if you have already downloaded it, please redownload and reaply the update.
