Flashing the official gingerbread in u8800 its irreversivel process, at least for now.
If you flash it you have to keep it as no way of going back.

If you root it using the only available method, bye bye!
Everytime you reboot the endless bootlooping starts and the only way to stop it is formatting data.
Which means everytime you reboot = bye bye all data and apps etc.

I think is something that its major importance and no one is mentioning this!!!!

I don't know, maybe I've been preaching to deaf ears or something...but...you can re-install the old ROM back, the CWM recovery won't work with the official GB - that much is true - but you will be able to downgrade to an official 2.2.2 (I used the B162) version with the regular update method (at least I was and everything is working just as normal as it used to).

So, irreversible - I don't think so
with the current CWM recovery - it's a no-go

edit: that being said, what works for me, doesn't necessarily work for everyone, so be careful and blame the guy in the mirror -not me, if it doesn't work for you. =)

I think Huawei says wrong here. I flashed 2.3 yesterday. After that, because of the haptic issue I flashed back to official 2.2. Only problem after the 2.2, recovery console had opened. I did factory reset there and phone started without a problem. Then, I had upgraded to 2.3 again. Still haptic don't vibrate. Other than, no problem here. Maybe, I will go back again to 2.2.

Well you are lucky then because you are the only one.
Perhaps what is saying in the official intructions that will be impossible to dowgread after this upgrade won't apply to you.

I have try it with at least 8/9 versions of official release and nothing works!!!!

Have you tried with internal sd? I copied dload folder to internal and started the upgrade process from Storage-Upgrade Firmware. Where did your phone stuck?

Edit: I didn't root my phone. Waiting proper solution. I had used B138.

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...

yes I made it with this B162.

**** this **** I'm going back to custom rom.

No point of using this official release if future customs will use the libs from this one.
