Bricked U8800 - how to unbrick it? - SOLVED!!!

mesnati · Jan 6, 2012

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

Any reference?

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

So it doesn't turn on in any way? No reaction when inserting USB?

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/341011-ultimate-guide-to-the-huawei-u8800/ drivers but it says no valid driver or something

Same is in the PINK screen:
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 (

mesnati · Jan 6, 2012

There is NO WAY to install these driver from HUAWEI site:
http://www.huaweidevice.com/tcpsdownload/downLoadCenter?category=&flay=software&downloadID=Mzk1MzA=

I mean i can install drivers it but doesn't recognize these Qualcom blablabla

(

I tried on two diff computers without a success

Here is the screenshot:

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

I had the same problem but I managed to flash without the battery inserted, only connected with the USB cable, do not know why.

Yeah that's what i have written on my updated first post!
Thanks anyway!

portuga2 · Jan 7, 2012

USB cable is only to provide energy, the files must be on the sdcard, and make the key combination for me only flash in this way, with battery does not work.

Glad you got it solved. When you get a new one, you'll have two phones?

The method without battery didnt worked for me

But when I wanted to put a different software on sd i found a file sd_update and i tlooks like this:

notes

dld_file_ptr != -1) !
dload_sd_file_data_proc-(dld_retry >= DLOAD_RETRY) failed!
notes

dld_file_ptr != -1) !
dload_sd_file_data_proc-(dld_retry >= DLOAD_RETRY) failed!

Does this tell anything except that the update failed?

such topics have to be sticked imo.

Hi, I'm having a problem with my phone. I installed the official 2.3.5 ROM and rooted it as well, and everything was working.
Then I decided to remove the bundled apps after this tutorial -
http://xdaforums.com/showpost.php?p=21354334&postcount=77

After that I always got a force close error after starting because of some status bar error thing (the tutorial is somehow flawed). Anyway I decided to re-install the new official 2.3.5 ROM again.

Did everything the same as the first time, but this time the update failed on step2.
I did a bit of Googling and it seems to be the same problem as mentioned in this thread -
http://www.intomobile.com/2010/09/2...te-failed-error-while-installing-android-2-2/

Meaning I removed some bundled apps and now it wont let me re-install the official ROM.

I can't get into recovery anymore because the failed update must have corrupted something. I can get into pink screen with the SD-card removed, but nothing appears under my computer. If SD-card is not removed then it always wants to start installing the ROM and then fails on step 2.

What can I do at this point? Do I have to format the SD-card with some other device and put something on it as pointed in the intomobile.com link? I am pretty clueless as to what to do

yannn007 · Jan 13, 2012

The bootloader is locked - this is why nothing shows on your computer. In think that at this point the only thing you can do is to try to install different offcial ROMs or take your phone to the service center.
