I have try it with at least 8/9 versions of official release and nothing works!!!!
Well, like I said, what works for me doesn't necessarily work for you.
Anyway, this is what I did and it worked, maybe it can help others.
0. Copy the original B162 ROM ("dload"-folder which has two files, UPDATE.APP AND UPDATE_CUST.APP) to the root of your SDCARD
1. Update to B162 by holding down +- keys while turning on the phone
2. After the first reboot, it's giving error messages for not being able to mount this and that...just ignore it and...
--> Wipe data / factory reset --> remove battery
3. Update the B162 again --> this time everything should go OK, if so, your phone is back to stock B162 and you're ready to use it or update a custom rom (just install Clockwork recovery like you used to and start from there)
The last point (3) may be unnecessary, but I did so just to make sure everything's ok.
Edit: OK, and I meant b162, not b160...
