I have search whole internet how to unbrick Huawei U8800 no luck
Anyone knows how to unbrick it without taking it to service? (I already get new one from my telecom provider in warranty period).

Is there some step by step unbrick procedure?

I have seen there is procedure for Samsung Captivate but not for Huawei
http://forum.xda-developers.com/show....php?t=1206216

Any reference?

Brgds,M.

UPDATE: 7. Jan
--------------------

Symptoms:
Can get into PINK and BLUE screen but cannot update phone. It stuck in:
Firmaware update step 1/2
Unpacking

... and there it hangs or sometimes saying: Update failed

----------------------------------------------------------
SOLUTION:

I found the way and it is so simple i couldn't believe it

1) Remember which ROM you have installed prior to bricking your phone (i had official GB V100R001C00B522G001)
2) Format SD Card and copy dload dir (for V100R001C00B522G001) to root of your SD card.
3) MOST IMPORTANT STEP: PULL OUT THE BATTERY from your bricked phone
4) Insert SD Card into phone
5) Connect your phone using USB cable to your computer
6) Wait until it says: UPDATING

That's it

The battery inserted into phone was causing why phone cannot be updated So you have to updated it WITHOUT the battery inserted!

Hope this helps!

You can buy me a beer

I am getting into PINK screen but cannot install any original firmware: it just hangs while trying to install from dload directory from SD Card. It says:
Firmaware update step 1/2
Unpacking

... and there it hangs

I tried two official updates:
V100R001C00B522G001
and V100R001C00B138SP04CUSTC185D002

but with no success
I also tried 2 different SD cards.

If i try to get into recovery mode (VOL +, Power) i am getting BLUE screen

Latest firmware installed on phone was official GB: V100R001C00B522G001

btw: no reaction when inserted into USB

And on blue screen it does not mount usb too?

I actually have an idea that we could hex replace pink screen from B518 to B522.

In blue screen it found hardware:
Qualcomm CDMA Technologies MSM

But it failed to install drivers. I tried with http://android.modaco.com/topic/3410...-huawei-u8800/ drivers but it says no valid driver or something (

In Ubuntu, it should mount without drivers, but it doesn't, so yeah, that won't help.

I will help again tomorrow when I can investigate update.app to see why it fails on unpacking.

I have Ubuntu and i tried also
With dmesg i cannot find device (sdb or sdc)
Any other idea?

Btw: before unbricking my device i did: dd if=/dev/sdb of=u8800.img bs=512
and created big file 3.8GB.
But now i cannot restore it if Ubuntu cannot find device
