This is a painful message to write, but I am desparate. This should be so simple!
Have a U8800 standard (at least it says only "U8800" in settings/about phone.
What have I done:
- Upgraded some time ago to 2.3.5 Rev B522 from Huawei.
- Then rooted it with SuperOneClick.
- Installed ClockWorkMod from Play Store.
- Downloaded CWM Recovery 5.5.0.4 stable from xda and placed the file into the /.cust-backup/image folder via Remount.
- Turned off Fast boot under settings/applications
:: What worked/happened.
- Rooting went fine, ES file explorer and others get root-permissions ok.
- But got into CWMRecovery only via CWM program (Choosing "Reboot into recovery"). Never with the holding buttons vol+ and power-button during power-on.
Figured it was that locked bootloader on B522 that was the problem.
What I did:
- Followed the instructions in http://forum.xda-developers.com/showthread.php?t=1457490 (Get your pink screen back).
- In CWM Recovery flashed "update-B518-bootloader.zip".
- Got "ok installed or something to that effect" from CWM Recovery.
:: What worked/happened.
- Still could not get into CWMRecovery via button-holding. Tried reflashing the B518 bootloader a few times, but just no difference.
Read somewhere that each Huawei firmware-release comes with it's own bootloader, so lets try to install Huawei B518.
- Only place I could find the image was here http://huaweiideosx5.blogspot.no/2012/03/u8800-b518-23-software.html
- U8800V100R001C00B518G001.zip
- Had to take out the external SD-card to get the /sdcard/dload directory on the internal SD-card.
-Seems to be important to have dload on the internal SD-card and not the external.
- Booting the phone with vol+, vol-, power did not start the downgrade, but was able to trigger it via settings/storage/software upgrade.
After downgrade to B518 (Checked version in settings/about phone):
- Deleted /sdcard/dload directory.
- Rooted with SuperOneClick
- Installed ClockWorkMod from play store again.
- Put CWM Recovery 5.5.0.4 into ./cust_backup/image again (think this was unecessary. I think it was already there but did it anyways)
- Turned off Fast boot under settings/applications.
:: What worked/happened.
- The phone is now in B518 software, but still can not get into CWM Recovery via keypressing at boot.
I hold the vol+ and power-buttons all the way to "desktop" so to say, but can not for the life of me get into CWM Recovery that way. Getting into CWM recovery 5.5.0.4 via instructing CWM application to boot into recovery works fine, though.
I am drooling at the thought of ICS Aurora, but I don't dare before I can reliably get into CWM Recovery via keypress.
Sorry if this is very stupid post, but I have tried so much.
Maybe the volume buttons are faulty? Turn off the phone and try this: hold down volume up; while holding press power button as long as the logo comes up. Release power button but continue holding volume up. If it did not work, try doing same with volume down.
Yeah, do what Blefish advised you but do it while the phone is off and charging. I have a kinda broken power key and with this 'trick' it boots faster and more reliable. Keep holding the 3 buttons until you see the recovery.

Thank you both for trying to help me here!
Unfortunately I have had no luck with your suggestions.
Re: Broken keys.
Power and volume-buttons seems to work well when the phone is on. Also when I boot into recovery through the CWM program, navigate to advanced/key-test, the vol+, vol- and power button seems to work well there too.
On pressing the power-button, CWM-R reports Key: 116
On pressing the vol+-button, CWM-R reports Key: 115
On pressing the vol--button, CWM-R reports Key: 114
So I think the keys must be ok, right?
Blefish: I did what you suggested, as I understood it.
When the phone boots, there are three stages of logos.
1. A static logo of Huawei's red "fan?".
2. A short "comet" animation.
3. An animated logo of Huawei's "fan", where some highlight flashes from left to right over the fan.
I hold the power-button in until I see the first static logo, then let go of the power-button and hold the volume-key(s).
Is this the same stage in the boot-process that you were thinking of?
I have tried vol+, vol- and both vol+ and vol-, together with releasing the power-button at that point.
Have not had any success with that, and ended on the "desktop" each time.
AceDroidX: I tried your suggestion as well.
I did this:
1. Shut down the telephone
2. Plugged in the power.
3. A "fan"-logo appears which is replaced by an animated battery.
4. Upon seeing the animated battery, I tried the various key-hold variants.
- vol+ and power : Ended up at desktop.
- vol- and power : Ended up at desktop.
- vol+ and vol- and power : Ended up at desktop.
So not much success either.
I am out of ideas... Can it be that B522 bootloader that still lingers in there, not replaced by installing the B518 software?
Well, idk what else to suggest.. Maybe your problem is here?

I remember that when i mount my phone in linux, there was a partition with just the image folder. Some files like boot.img and recovery.img where there. Try to put the recovery image in there and see if it makes any difference.
I'd like see your versioninfo, can you upload a screenshot?
You can check mine from B528
AceDroidX: When I use Remount, I am able to mount that partition as read/write so that I can copy CWM's Recovery image in there. I think it is identical as mounting it up remotely, as you do. I am after all able to boot into CWM-Recovery, just not by key-pressing? I suppose I could boot into Linux and try to mount up the partitions as you do.
Hi kilroystyx: I can not figure out where to find a similar-looking page as the one you have in your picture.
I have the settings/about phone, if that is an older version of what you have there?

Based on the screenshots your installation is fine.
Just one last shoot based on what AceDroidX says, with phone off press Vol+ and hold then connect USB cable to PC or charger and stay holding Vol+ then wait...wait and what you see?
hi all,
i'm using some ics roms and it seems ics supports natively vol++power button to take screenshots but it doesnt work for me... do you know if there are some custom ics rom where it will work?
thank you
Wow.. It is hard to believe.. but I have actually ... eventually found a way to get into that CWM-Recovery every time.
It is a combination of your suggestions.
I have been doing variations, trying to figure something out and eventually there is a method.
What I must do, on this phone, in order to get into CWM-R is this:
1. If the charging cable is in, then unplug first.
2. Turn the phone off.
3. Take out the battery and put it back in.
- This makes a difference on my phone, at least. I am not able to get into CWM-R wihtout taking the battery out first.
4. Press and hold Vol+
5. With Vol+ being pressed continously, insert the charging-cable.
6. Wait for the Fan-animation to finish and the "battery-charging" animation to start.
7. When the battery-charging animation is running and the screen eventually goes black, keep holding the Vol+ button for some time.
- Sometimes it works to keep holding the Vol+ button for only a second or two. Sometimes I must hold it up to 30 seconds.
7. Press and hold the power-button in addition to the Vol+
8. Wait for CWM-Recovery to start.
Thank you very much for your help.
Now I think I can try for ICS!

I am trying to do an nandroid back up. The instructions say to power off, then hold the "Home Key" and the power button untill you see the triangle.
I am holding the picture of a house next to the menu key. Is that the correct key?
My unit just turns on normally even if I am holding mentioned key, which is the wrong key cause it should not have power until the phone is on and unlocked.
Thanks for help.

On the Droid 2 you have to go through a different way.
1. Make sure you have Koush's bootstrap app for the Droid 2.
2. Make sure you are bootstrapped via Koush's app.
3. Reboot to recovery through Koush's app.
You navigate menus with the volume buttons. You select with the camera button, and you go back with the power/lock button.
you can also utilize the keyboard arrows, use ok to select and delete to back up.

Ok, got it from the Market and it installed. I started it and did not know what to do, so I hit the first button, then the second button, then went to Backup/Restore and chose backup.
It is working as i type this.
Thank you so much
yes you would select backup. Once you do this it will backup to you backup folder on your sdcard. If you were to need to go back, you would utilize the restore option and select whichever backup you wanted to use.
if your phone is boot looping or anything to get into recovery:
-start up phone
-let the phone go to the bootscreen (the droid eye screen after the M logo)
-pull the battery out while in the bootscreen
-after a few seconds replace battery and boot up phone
-phone will boot into clockwork recovery

Good advice. I believe there is a flag that gets set when you shut down the phone, and it only gets reset when you successfully boot. That way, if you boot loop, when you try to boot again it goes to recovery.
This also manifests itself sometimes when you flash a rom. Everytime you boot, it first goes into clockwork recovery, which is annoying, but fixable. This problem occurs because you need to bootstrap again which allows the flag to get reset when the OS loads.
only bootlooping when connected USB
I dont know what happened I simply had my phone attached to my pc in USB mode (after transferring music to the sd card via "media sync") and when I switched to 'charge only' and attached my head phones, my phone went into a boot loop. i unplugged USB cord and bootloop stopped... anyone run into this at all? kinda frustrating since now i apparently can now longer attach to my pc.
any help would be greatly appreciated

apparently it was a problem w/my pc! it was giving me problems disconecting or even accessing my portable hdd as well.
so: Problem Solved
Restoring of brick Huawei U8800.
All do at your own risk! I am not responsible for your machines!
Today I was able to magically (just wonderful, because it found the time at which there is a chance to run the update) to recovery from a brick Huawei U8800 (corrupted bootloader + recovery not run + in a pink screen not mounted hard drive + when trying to update the written Update failed! I spoke to a service center, they said the warranty is not the case and we must change the motherboard (the cost of 3-4 million BYR, new at the MTS salon cost 2.9 million BYR )
What and how I did:
1) To restore I'am using the firmware B162 Android.
2) Format the micro SD card that was clean (I was 8 gb, 2 class and be sure to FAT 32) and unpack "dload" folder and ".txt" file(with a strange name) from the downloaded archive to sdcard.
P.S. I say that not all flash drives can operate restore, I have like three went, normally only one.
3) Insert the micro SD into the phone and pull out the battery.
4) Hold down the Volume (+) and power up, hold and connect the phone via cable to your PC, your phone will be switched on and the logo appear, then turned off my phone (missing logo). So, when the logo will disappear (ie the phone will turn off) and immediately hold down the volume (-) the volume (+) and power up.Main that the updating process can start only one time after the logo was gone, if after a few times in a row press both the volume keys and power up, updating does not start, it is necessary to re-clamp the volume (+) and the power up, after the disappearance of the logo, both the volume and the power up of ... I have to go to the upgrade process if you wrote "Update failed!", try again (I went with 2 times).
5) After a successful update, the phone will reboot, on reboot he should loaded the standard blue recovery.
6) Turn off the phone from the computer, insert the battery, hold down the volume (-) the volume (+) and turn on, wait until you get a pink screen, release the button and connect it to your computer. You should see a new device and to define a disk drive with a folder "image". If we define - rejoice!) If not, then you need to install the driver on the internet enough to the driver, as well as the wood in my going to the Android SDK, not sure ...
7) Thus, we can assume the phone repaired) Download recovery 4.0.0.5 and unpack the archive and copy the file "recovery.img" to a folder "image" with the replacement. A man does not 4.0.0.5 recovery loaded, it is strange, but recovery 5.0.2.7 normally loaded
8.) Disconnect the phone from the computer, pull out / insert the battery and try to enter the recovery (volume (+) and power up).
9) If set, then everything is OK and can now be sewing. I still put 2.2 Geno v8.4 + software package from Google, but I recommend again read all instructions on the firmware, to avoid problems!
Good luck, hope that helped someone, he sat on the forums more than one day, but have not found a solution.
If someone has turned out, a sign of gratitude you can throw money on my phone +375297176005 (MTS, Belarus), would be very grateful
P.S.
Instructions is my and it's my first, that do not copy and paste, you can search the Internet. Do not judge strictly, if something is not designed ...
If there are people who helped, I think you can throw his hat in the description. My message is also present in our 4pda.
Hope springs eternal
Sorry for my english, I'm from Belarus and bad know it

Just thought I would mention it, if you connect the pink screen to Ubuntu/Linux, it will most likely mount.
Just tried this recovery method on a bricked U8800. Didn't do anything at all. Must admit that it was bricked in a way that i didn't see anything at all on the screen. Neither did i notice anything in dmesg on a linux machine.

Hello.my huawei u8800pro v.2.3.5 brick after install official ice cream sandwich.I followed the procedure and now I have a new removable but I can't go to recovery mode!!can I install a new rom?
Ok I have been using the ics leak (version 19) trying to install custom recovery.
All the instructions for going into download mode says to insert paperclip into reset and while holding down reset press power button for exactly 3 seconds then after 1 second release reset button.
My problem is while reset button is pushed in the unit does not respond at all to the power button period. tried it for an hour. Reset button works. power button works. Power button with the reset button pushed in does not work at all.
Is it possible in the ics leak they have disabled the download mode??
Just thought I would update with more information
adb reboot works
adb reboot recovery gives me blank screen. If I hold down power again it will eventually go into recovery mode and tell me recovery is broken (red triangle).
adb reboot download gives me a blank screen like the power is off.
I an thinking my power button may be bad as I have to hold it down for 10 seconds while it is off or in stand by to get it back on or off of stand-by mode.
Anways tried for an hour and a half. Hopefully someone has a clue on this...

I'm confused not sure what you are trying to achieve here. Need more info.
1) which ics leak have you installed?
2) To install a custom recovery using Acer Recovery Installer from the market is easiest. it will backup and restore and allow u to flash roms, does not work for 3.2 tho
3) Download mode is used with the acer upgrade utility (EUU) to rollback to HC 3.2 from ICS or to go back to stock NOT to install a custom recovery.
4) The button press method to enter custom recovery is vol down/power.
So if you can post a bit more info i'm sure we'll get you to where you want to be

I was using the guide here to install the unlocked bootloader then CWM. Sorry I was not more specific.
http://forum.xda-developers.com/showthread.php?t=1516012
Sorry it worked finally it took 2 hours to get into the mode. It seems my power button does not work very well. I had it pressed in for almost 20 seconds for it to take. I noticed that the only way to know before plugging in the usb is to watch for the power button to light up white.
Maybe the guide should be updated to let you know the screen will be blank untill a later part of the process.
At least I was able to get the bootloader unlocked now and CWM recovery install. I may still have to send the unit in if the button stops working.
So I have this strange issue. I just tried shutting my tablet down so I can reboot to recovery to flash something. (Mind you, I haven't flashed anything in a few days)
So I shutdown and I can't access recovery. It just wont boot. Vol+, Vol- and Power at the same time. I tried going power first, then volume and vice versa but no dice. My volume buttons and power button work perfectly fine while in the ROM.
Now at this point I was like, "Screw it, I'll boot into the ROM" but no.... It wouldn't even turn on. I tried plugging it in and nothing (~70% battery when shutting it off). Then I plugged it into my computer and it showed "Device driver software was not successfully installed" with a device named "QHSUSB_DLOAD".
Quick Google-ing made me think I bricked the device. I ended up just holding on the power button for a good minute and it finally booted into the ROM. I'm still unable to boot into recovery via Power + Volume Buttons... I have to use an app to boot me into it.
Why? What happened / is happening?
I'm not sure with the N7, but with my SGS III that's what happened when it bricked.

Could you double check you are pressing the right buttons based on these instructions:
[Info] Guide to entering safe mode, bootloader, stock recovery
You are NOT supposed to press 3 buttons, Vol+ and Vol- and Power as you described, rather just 2 buttons depending on whether you want recovery or bootloader.

Well now I feel like a total dimwit.
I guess I was so used to my Galaxy Nexus... I did a Google search on how to access the N7 recovery but I guess I glanced over the instructions too quickly.
This thread can be locked, lol.
BTW sorry, I fixed the link.
Here's my problem.
I can't get into recovery by pressing the power up, home, power buttons. It says it's 'entering recovery', but then it gives another 'buzz' (like when the phone starts), and just reboots normally.
I used to be able to get into recovery with ROMManager, by selecting the 'boot into recovery'. Then I just got into my CWM and could do whatever I wanted. Now I can't do that anymore, probably because my device is not rooted atm (got CM12 on it though). I wanted to root it, but I can't get into recovery.
I already tried flashing TWRP with Odin (download mode does work), but that doesn't work either. I obviously searched google and XDA for the problem, and I saw suggestions for other phones, like updating the bootloader. But I can't find any information or files for updating the bootloader.

Reboots trying to go custom recovery are normal sometimes.
Lil guide for enter custom recovery (TWRP):
1. Power off your device completely.
2. Press and hold Volume Up, Home and Power buttons simultaneously.
3. Release only the Power button when the logo of Samsung in white appears (you will see little letters in blue and red on the top left of the screen).
4. You will see the blue logo of TWRP (pic attached) then and you can release all buttons and start to navigate for the custom recovery.

Thanks for the reply, but I don't think you understood my question. I know how to get into recovery when it all works. I've done it many times before. The problem is that it shuts down while booting into recovery, and then just reboots normally.
I only installed TWRP because CWM wouldn't work, but TWRP doesn't either. So I guess it has to do with how the device boots into recovery, regardless of what the recovery is.
Anyone? I kinda want to flash another ROM, but I'm unable to right now.

I don't think that's the problem. I have 0 issues with the power button. Also, when I try to boot into recovery, it actually says it's 'starting recovery'. Then it stops with a buzz and reboots.
