In the newer official ROMs, Huawei included a "feature" to lock the bootloader and therefore, get less bricks. But happened the opposite - if your cust partition gets corrupted/deleted, you'll have a high change of bricking your device.
The new bootloader is not actually locked, it's changed to use QPST (Qualcomm Product & Support Tools). As it needs a code, we can't use it.
This method flashes the B518 bootloader straight to your phone, so you will get back USB.
Apply only if you have upgraded your phone to B522 or newer. You may have a custom ROM on top, but the base has to be B522 or newer.
Tested by myself on B522, B526 & B528.
The steps required to get back pink/blue screen USB:
Automatic flashable zip is pretty much fail proof, but I have warned you.
Automatic method (recommended):
Download update-B518-bootloader.zip from MediaFire.
Save it to the root of your SD Card.
Start the phone in recovery mode (recommended recovery is 5.5.0.4)
Select "install zip from sdcard"
Select "chooze zip from sdcard"
Select the zip you downloaded before.
Select yes.
Reboot and enjoy!
NB! Be careful when doing this manually, one wrong move and your phone might get bricked.
Manual method (not recommended):
Download the bootloader.bin (B518) from MediaFire.
Copy it to the root of your SD card.
Use a Terminal Emulator if on phone or start ADB and write in "adb shell".
Write in "su" to get root rights.
Write in "dd if=/sdcard/bootloader.bin of=/dev/block/mmcblk0p3" to copy the bootloader.bin from SD card to the bootloader partition.
All done!
Protip: When using Linux distribution, pink screen mounts your internal SD card, data, cache and system partitions. This happens because Windows does not mount extX partitions by default.
I suggest everyone to do this as long as you have rooted your phone and want to flash custom ROMs/kernels.
Now you can recreate your backups with this tutorial.
Special thanks to dancer_69, who sent me B518 bootloader.
Thank you. This is going to be useful.
Was this the more important thing than rom?

Used the zip file method... yes, pink screen supports usb again, but phone now boot-loops and I can't access recovery anymore. Will try to flash Stock Rom again :S ****! Will report if really bricked
EDIT: can't flash ROM anymore, and can't access recovery... I guess I'm pretty much screwed... can someone post the latest bootloader from huawei (the locked one)? I still don't know how i'm going to installed it since I can only access the pink screen and nothing more... It's really bricked isn't it?

Also, my partition scheme is showing like this (I don't know how it was before). Is this normal?

Its not bricked, relax. Someone else will help you, I can't help via phone.
What recovery did you flash it on? I tried it several times and it worked fine. But in your case, I believe the partitions got messed up, not sure how. And when you remove battery, reinsert it after 10 secs, then try to start recovery.
Sent from my U8800
I've flashed with "official" 5.0.2.6... I know, I know, the firs post states 5.5.0.4, but i got dumb somehow... even worse, I have previously customized my partitions to have more internal space via one of those scripts that are available on the site, so maybe that was the problem.
At this point I'm installing stock rom via dload method.
It wouldn't install before, when dload folder was in the sdcard (Windows wouldn't mount phone's internal memory in pink mode, but luckily, ubuntu mounted the all the internal partitions correctly, so i copied the dload folder to the internal memory and is now in the installing phase... will report if that worked..
I guess I should have firs install recovery 5.5.0.4 in the pink screen and then try to access it, but my brain is all messed up at this moment...
bye bye, saturday night out with friends :S
EDIT: install of stock ROM (BTW, back to 2.2) completed, phone is restarting, lets see...
EDIT 1: formatting data... I guess it's working... lol
EDIT 2: new restart
EDIT 3: Successfully booted into ROM!!!
EDIT 3: In the process of installing and trying to access recovery
I still don't understand the conflict. The partition table should be then fine, if you modified it before the flash. Did you have fast boot on?
I am happy you got it fixed

Mine also wouldn't boot, but pink screen successfully made usb storage work. Try pink screen in ubuntu and see if it mounts your partitions. Then install stock rom again with dload folder method (copied to internal memory), that worked for me...
good job 1st of all, 2 things though,
I've been wondering, .35 kernel ROMs all seem to have the same problem, phone reboots when waking up with wifi on. This is a problem in either miui, CM7 and also, official.
Which leads me to conclude that this is kernel related and probably won't be fixed until someone, (hopefully Franco) picks the kernel up for a revamp.
Are my assumptions correct?
Also, if someone is to use custom ROMs does it make any difference if we upgrade to latest official or straight from beta 1?

Whee! I knew it was doable.
Many thanks and all that.
blefish look at pm
2.2 has pink screen already unlocked, so that has nothing to do with this. This is for flashing only if you have a locked bootloader, which is the B522 ROM.
I am creating an app to backup your phone fully even if it is turned on. That way there is a chance to restore the phone if something brakes during the process.

Nope, but for the information, it's going to be an app named X5Toolbox, and from there you can flash recoveries, boot images, bootloaders, perhaps even AMSS, restore and backup IMEI etc.
I am stuck at a blue screen, and I was told here that I need some linux backup that someone might have made so I can restore it to my phone and everything would be ok and back to normal again!
I really need as soon as possible because my phone is bricked and I need it!
The last thing I flashed to my mobile, was the official 2.3.5! for x5
Ok, here's what you should do:
Download this.
Connect phone to USB.
Copy the zip contents onto the phone (partition with size about 252mb).
Remember to keep the folder structure partition/image/boot.img etc.
Restart - if system is not corrupted, it should boot.

There is a problem, when I connect to USB and press Volume Up + Volume Down buttons to get to the purple screen it aint reading my phone as a device or sth I can put files into it!
Something with the drivers!
That was occurred even before that blue screen happened, when I installed the 2.3.5 official and the the drivers with SuperOneClick!
Ok, do you have a external SD card? If you do, check this.
After applying that, try to do the steps I posted earlier.
thanks I will this night, because I got lessons to attend at the moment!
Thanks a lot, you offered a great relieve!
I did it! I am back at official 2.3.5!
But I cant root :/ SuperOneClick Crashes when i press ROOT! Drivers and everything are installed!
It just wont root!
And I also tryed to first install SuperUser first!
See this thread for other rooting methods. I've used Doomlords method and it worked great
Hi all,
Need help with my phone... :\
So I wanted to install ICS on my phone today (http://forum.xda-developers.com/showthread.php?t=1492957) and I looked at the instructions, obviously you have to have a stock ROM installed first before going for the ICS update. At this time I had CM7.1 installed. So I chucked the files on my SD Card to install (the ICS and Stock) and went ahead into clockwork recovery to try and install the stock ROM first. This didn't work, as at the time I didn't know you have to install it via the pink screen and extract the zip folder and put the dload folder in the root of the sd card. So when I tried to install it, it said starting installation, and then would say installation aborted, I had no idea why, so I tried another couple of times, still didn't work. I then updated my clockworkmod recovery to the latest version for the U8800 and it still didn't work (as I was obviously doing it wrong...). I also happened to have an update for CM7 on the SD card that I never got around to installing (7.1.0.1), and so I tried to install that and again it said installation aborted (not sure why that didn't work, should of...). So then I thought, that's odd, nothings working, betcha the ICS ROM won't install either, see if something else is wrong, so I pressed install... and it started installing... not exactly what I wanted or was expecting. So it seemed to install alright with no errors, so I did a reboot out of recovery. It then stuck on the white Huawei logo screen and just stayed there... some folders got created on my SD card (apps that I had installed on CM7), no idea why, it didn't seem to boot, left it for 5 minutes and still just the white logo screen.
So I then did some more reading and learnt that I needed to put the official ROM's dload folder to the root of the SD card and install it via the pink screen. I tried this, unpacks it fully and completes step 1, but it gets to step two, and 5 seconds later after it starts attempting to install the ROM it says, Installation Failed.
So I was looking around for people who had a similar problem as me, and found some, they found a way to fix it which was to put the dload folder in the root of the internal SD card, unfortunately I have no idea how to get to that when the phone doesn't boot up into the OS. I tried putting it in the internal storage via the pink screen, but that's only 200-250MB in size, and the file needs around 300MB, so there wasn't enough room. I tried repartitioning the storage hoping this would increase it, or return it to normal (as I had partitioned it before to the 1.42GB/1.12GB partition that others had posted up previously) and it didn't change a thing. So I have no idea how to get to internal storage D:
Not having fun so far... so I thought I might try and install CM7 again, and then go to stock, and then to ICS, or maybe just leave it on CM7 and give up for now. Unfortunately the version of CM7 I had isn't available anymore, and the newer version you have to have stock ROM installed first, so I decided to grab oxygen instead. Downloaded it and chucked the zip folder onto my SD card and tried to boot into recovery (Power+VolUp) and now it won't even go into that! It goes to the pink screen (Power+VolUp+VolDown) without any issue and I can connect to the computer and access the files on there.
So basically, I've bricked my phone and I would love it so much if you could help me get it back, I really don't want to have to go back to my old Nokia 2760 (http://www.gsmarena.com/nokia_2760-1975.php) where the speaker doesn't even work, so if I make/receive a call, I have to put it to loud speaker or headphones to actually hear their voice... would be much appreciated.
Thanks,
Gunny
I think you have some hope left if you can go in the pink screen mode. You should find some istructions from general section and Q&A section. If you can go to pink screen you should be able to install official Huawei rom.

I finally got it all sorted, if it wasn't for that pink screen, I'd be stuffed!
I had to go back to a 2.2.1 ROM before it would finally accept it and install. Had a bit of cache and corruption, but android eventually cleared/cleaned itself and put itself back to normal. Now I've got the official version of Gingerbread on my phone, and I'm not sure if I should upgrade to the official version of ICS or whether I should upgrade to Aurora's (http://forum.xda-developers.com/showthread.php?p=22682229#post22682229) version of ICS. Thoughts? And don't worry, this time I won't screw it all up!
Thanks all!
Alright, just discovered my official ICS ROM is for the U8800 pro, not the standard one, so I guess I will be going for Aurora!

I have a Huawei U8860 and wants to go from custom rom MIUI to stock rom B925. Can I just follow your advice here and install it via the pink screen?
Hi, this is just a recompilation so that people don't have to get confused and scared.
Before your read this, please understand that this happened because of my own stupidity at somehow managing to delete the /boot from recovery 5.5.0.4, and caused a BLUESCREEN. When I tried to go to recovery, it went back to a pink screen. There were also other issues, such as a corrupted internal sd partitioning (warning, please be careful about doing partition, i highly recommend a proper partitioning zip which i'll link later in the post). In the end I was able to revive from the soft brick, and continued on to reinstall CM10.1 (it was version 7 at the time of the crash)
OKAY, let me repeat. Probably at this point you have a phone that has bricked. But if you can access PINK SCREEN, you're in luck (EVEN IF YOU DO NOT HAVE USB connection, its fine, as long as your EXTERNAL SD CARD is still accessible, physically.)
I'll put the stages in below:
WARNING I am not responsible for any loss, damage, or earthquakes or whatever crap that happens. Do this at your risk. Before you proceed, PLEASE OPEN THE BATTERY AND LOOK INTO THE BACK OF THE PHONE AND MAKE SURE IT SAYS MODEL: U8800 NOT U8800H, NOT U8800PRO. THIS IS FOR U8800 (okay, I admit i'm using U8800H but this is just an exception, probably)
PREPARATION:
STAGE 1: Getting the PINK SCREEN and booting into 2.2 Froyo / 2.3 Gingerbread
STAGE 2: Getting the TOUCH RECOVERY / CLOCKWORK RECOVERY, ROOT and SUPERUSER into the phone.
STAGE 3: Flashing the recovery, the partition, and the firmware
STAGE 4: Miscellaneous
PREPARATION

There are a few things that you need to prepare before hand.
1. A working computer (in this case i use windows)
2. Huawei USB drivers for windows. http://www.mediafire.com/?5z6i5cv8l6br292
3. Huawei Gingerbread base 528 ROM (this is BOOTLOCKED but don't worry, we can fix it just read up)
http://www.huaweidevice.com/cn/downloadCenter.do?method=toDownloadFile&flay=software&softid=NDEyNTU=
4. BLEFISH's "get back your pinkscreen" zip file (to be used with item 3, listen!) http://forum.xda-developers.com/showthread.php?t=1457490
5. Super One Click http://www.multiupload.com/9AJDSU1Q11
6. Blefish's recovery.img for the CLOCKWORKMOD recovery
7. Forumber's PARTITION.ZIP (the better option thus far) http://forum.xda-developers.com/showthread.php?t=2145187&page=124
8.. A ROM OF YOUR CHOICE (http://forum.xda-developers.com/showthread.php?t=2166353) as for me i'll just wait for Blefish to release his version of JB / CM re-write.
Now we're done, let's proceed
BEFORE YOU BEGIN:
*credits to forumber2*
Forumber2 wrote in one of the responses (not in this thread) that caught my attention. Apparently, if you're using a B158 bootloader, you can still access the STORAGE if you remove the battery and plug in USB for 1 minute.

I am not sure what steps to take this (it is a new information for me) but I presume you can immediately restore the TCRW from there. Have to ask forumber2 though.
STAGE 1: Getting the PINK SCREEN and booting into 2.2 Froyo / 2.3 Gingerbread
Here are the steps.
1. Install the HUAWEI drivers for the phone, and also SUPER ONE CLICK for windows.
2. Take out the U8800's EXTERNAL SD CARD, and plug it into computer. (use a card reader if you don't have)
3. open (UNZIP) the downloaded OFFICIAL GINGERBREAD ROM. Inside it should be a manualand a folder called "STEP 1", and inside folder "STEP 1", another folder called "DLOAD".
3a) COPY the "DLOAD" folder (and its content) and place it into the ROOT of your EXTERNAL SD CARD. that means from your computer it should read like this: (when you navigate)
X:/EXTERNAL SD CARD/DLOAD/UPDATE.APP
(X is the name of the drive)
4. Unmount the EXTERNAL SD CARD, and then slot it back into the U8800 phone.
5. Pull out battery.
6. Stick USB into the port, and into computer. (WITHOUT THE BATTERY)
7. PRESS VOL+,VOL- and POWER together (Reboot into pink screen)
FIRMWARE UPDATE PROGRESS. it should be 1/2 then 2/2.
"Do Not turn off the device".
AFTER finishing step 4 (it takes some time)
there will be a "TICK" and it will say "RESTARTING".
QUESTION What if I can't? It doesn't work?
ANSWER There's another trick. Pull out the battery, plug the USB wire in (YES, just plug in without battery) and then boot into recovery. This should work. Assuming it does not, get another USB cable with data capabilities, and USB 2.0 ready port on the computer. This should provide MORE POWER to the phone (the phone has a weird failsafe system where it would not proceed with upgrade if the power is too low)
REASON: HUAWEI wanted the customers to have a simple update process, so they created the entire thing to just be unzip, plug in, and wait. Yeah. I know, you'll feel weird especially when other phones seem to be super sophisticated at this part and Huawei made it so easy. Even the remove the battery part. Yes.
QUESTION: But what if i'm stuck at 1/2? goddamnit?
ANSWER This did not happen to me with the file. Like I said, again, it depends on the firmware. What I've read and understood is that there is a possibility of 1) bad firmware (need to download another firmware) or 2) EXTERNAL SD CARD is badly formatted (please use an Android phone / tablet to format just to be sure) There's a thread with specific discussion about this but it was lost on my notes, but that's the gist about it. What I'll suggest you to do is download the 2.2 Froyo then upgrade back to 2.3 Gingerbread. Some people have made it through this stage by doing everything from 2.2 Froyo itself.
Reason: I'm not so sure what is wrong, but this is one of the irregularities that posters have asked when unbricking the phone.
NOTE:
After the installation part, it should restart itself a few times. Basically, after the big "TICK" and "RESTARTING", it will continue to restart again, and again, and again, and again. Then finally it should boot up properly, and then the HUAWEI logo, then the flying dust animation, then the Huawei lotus flower glowing animation, and then boot up into 2.2 Froyo or 2.3 Gingerbread (depending on your firmware)
QUESTION: Okay, I see the boot looping. However, it just boot loops, and does nothing. At times i see the animation stop. Something must be WRONG!
ANSWER This happened exactly to me. The answer was that for some reason the pinkscreen update DID not format cache and data, as well as dalvik, etc. This is a recovery issue. The way i solved this was, that I re-did the update (making sure that it really did update properly into the official stock rom), then wait for the boot animation loop, (which happened) Then, the next step was like this:
1. TURN off the phone.
2. Plug in battery (or remove it)
3. Plug in USB (yes, again!)
4. Hold POWER button and VOLUME UP button.
If you can somehow boot into a blue colored Android system recovery *3E* screen. This one is the recovery with menu, but it is HUAWEI's recovery.
5. FORMAT CACHE, FORMAT DATA
6. REINSTALL THE official ROM, (YES wait again for the "TICK" and "RESTARTING", then it should restart a few times, then boot up. Have patience and faith!
*note: apparently as noted by aashi02 when the said user was unbricking the u8800, the 3E recovery has a factory data reset which somehow clears up the entire phone and enables the phone to properly work with the stock factory-default firmware (instead of crashing again and again and again in 2nd boot onwards). So I would presume that after first boot, one would have to again boot into recovery and do a factory reset (or do it while in the settings in first boot). Not sure if there are any users to encounter "2nd boot force close syndrome" after this. (if there are, please tell me)
The phone should have booted. If it doesn't, please tell me. I can't help much but I'll try to record as many possible errors and steps to overcome it, if i see responses from others and proven to work.
STAGE 2: Getting the TOUCH RECOVERY / CLOCKWORK RECOVERY, ROOT and SUPERUSER into the phone.
Once you've got into the GINGERBREAD / FROYO, follow this thread

QUESTION: Okay, somehow somewhere when i boot the phone for the first time, its okay. Second time, everything goes to hell (Force Closure, errors, etc, i can't press anything!) Something must be wrong again! You suck!
ANSWER Well, yes, this happened to me. Again, please read the guide. I said, no reset. Just do everything in one GO. That's how i fixed the problem.
NOTE: by now you should be able to boot into CLOCKWORKMOD recovery.
STAGE 3: Flashing the recovery, the partition, and the firmware
This is where we want to go to, and this is where you want to fix all the problems. I should not need to elaborate here, but if you're reading this part, you can now close this thread and go to the ROM of your choice and install as per THEIR INSTRUCTIONS:
QUESTION: Wait a minute. Something's fishy. THAT EASY? You screwin' with me, noob?
ANSWER Technically it should. There should not be any other problems UNLESS you somehow again delete the /boot. NEVER EVER DELETE /BOOT. If you have installed any firmware higher than 518 (B522 and above) firmware, then you need to do the next step:

Notice the 526 in there? it means i installed base 526
QUESTION: Wait a minute. You asked me to download that frickin' partition.zip and what do you expect me to do?
ANSWER Read the answer to the next question.
QUESTION: Help! I haz problemz! i cannot install ROM! it haz fail / not enough space on my internal SD! helpz!
ANSWER IF, and I repeat IF, you're reading this, then you're probably installing something way bigger than the original partition's system partition. To help you imagine, think of it as a 10-car train. The basic idea is instead of 1 engine, you now put 2 engine, and sacrifice 1 compartment car (that means from "1engine-9car train" into a "2engine-8car train". This is where you'll find the partition.zip helpful.
BUT BEFORE YOU DEAL WITH PARTITION.ZIP, do install "GET YOUR PINKSCREEN" by Blefish, read it here:

I quote Blefish:

The new bootloader is not actually locked, it's changed to use QPST (Qualcomm Product & Support Tools). As it needs a code, we can't use it.
This method flashes the B518 bootloader straight to your phone, so you will get back USB.
Apply only if you have upgraded your phone to B522 or newer. You may have a custom ROM on top, but the base has to be B522 or newer.
Tested by myself on B522, B526 & B528.
The steps required to get back pink/blue screen USB:
Automatic flashable zip is pretty much fail proof, but I have warned you.
Automatic method (recommended):
Download update-B518-bootloader.zip from MediaFire.
Save it to the root of your SD Card.

B]QUESTION:[/B] Now what?
ANSWER Install your custom ROM as per your custom ROM's instruction.
B]QUESTION:[/B] No, really. Now what? I want to double make sure, because i don't trust you, noob.
ANSWER Okay, you need to format and clear, not everything. Follow these steps.
ROM Installation:
Use only Forumember partition.zip.
1. Copy package to SD card
2. Boot to recovery
3. Full wipe (data, cache, dalvik,) <--- This one is in main menu
4. Format /system, /data, /cache <--- This one is in ADVANCED MENU. NO NEED TO MOUNT and DISMOUNT, and DO NOT FORMAT BOOT
5. Reboot recovery
6. Install the custom ROM (and gapps if needed.)
7. Reboot. Take a deep breath.
The phone should now boot into your new custom ROM.
As per writing, i booted into CM10.1 v7 by ilyaa299. Still waiting for a better JellyBean ROM though.
Congratulations, enjoy your unbricked phone!
STAGE 4: Miscellaneous
Not all ROMs are created equal. And none stand peer to peer. No matter how many seasons have come and go, please remember the ROM is only alive as long as its developer remains commited to its releases and updates. Please thank them. They will appreciate it.
For most usage, I have no issues, except the piss poor memory of 300++MB. I have not found a way to solve this. There are APPS that claim to create a virtual RAM, but if you don't have class 6, or class 10 External SD card, don't bother, and from what I read it'll shorten your EXTERNAL SD CARD's life A LOT. use it at your own risk.
To help alleviate the situation, i installed "auto memory manager" and also "greenify". This has helped me a lot. Auto memory manager deals with current usage, but "greenify" deals with the apps that are inactive, but greedily and stealthily use RAM and hog it (as if they're some royalty of some sort)
One of the greatest points of this phone is that it has a SUPERIOR camera (even if its only 5.0mp) and it has superior HD viewing (watch movies, youtube, etc, in FULL HD, where other phones, even the MORE expensive ones cannot do)
Try to avoid apps that uses 'download as a process" like mangawatcher, because i somehow managed to fry my EXTERNAL SD card (total death) because i left it overnight to download some manga, and then it froze. Then again it probaby may be a ROM issue (its a custom ROM) but just be careful! I lost a 16GB class 4 SD card.

i made the same mistake, i would guess you formatted the /boot too.
you now have to take an original huawei rom, 2.3.5 will be suitable, and follow some instructions you should find in this forum already.
than u have to root your device again and install the rom you need.
Yes, you need to install the official 2.3.5 firmware again. Download it from Huawei's official website.

still does not work (pink screen)
Hello everyone, I did my homework by searching, but alas I could not revive my phone. (U8800)
How did it bricked: Installed CM10.1 v7, (ran fine, had to re-flash because i read that one must do /format system, /format cache, somehow probably i deleted something i wasn't supposed to, and now its bricked)
Symptoms:
1. Press power button: Blue Screen. This includes Power button and volume + together. Blue Screen. (NOTE: Huawei logo flashes briefly for less than 1 sec before screen goes blue)
2. Press power button and volume + & - together: Pink Screen.
3. (new#)Cannot access from Windows 8 (I have drivers installed, will not detect. Every time i plug the phone into win8 the phone boots up blue) but can't see internal SD.
What I know:
1. This is a U8800
2. CWM 5.5.0.4 was installed (it was bricked after i clear and format, and cannot re-enter the CWM anymore, it goes into pink screen instead)
3. Internal SD is not read-able. (this was documented when i wrote my issue, another forumer by the name of rqmok says its fine because i updated the partitioned.zip, therefore even if it cannot be read, but if it can be accessed from the android file browsers, it is okay. I believe him)
4. I can boot up the huawei + bluescreen, but no
What I did:
1. Because i was at CM10.1 v7, i renamed the entire thing as update.zip and place into external sd root folder . RESULT = nothing. just pink screen
2. grabbed an update (Gingerbread) from XDAFORUM u8800 wikipedia page (the international version), place as update.zip in external sd root folder. RESULT = nothing. just pink screen.
3# (new) I unplugged battery and the external SD, plugged the phone via USB to computer. Boot up (few seconds of Huawei logo) then bluescreen.
Yes, I understand that others have asked about this and somehow revived. What I've read, and understood was:
1. Blue screen = something about ./boot was deleted, and needs to be reinstalled.
2. Pink screen = still safe, has a chance to revive the phone.
What i do not understand:
1. Put ROM files as update.zip, but pink screen does not flash into any form of recovery.
2. Somebody from somewhere said use something called ubuntu / bt5 to "dive" into the phone's internal SD. (I don't know how to do this, and from what i understand it is risky because it involves partioning the internal SD again.
3. Any other way to rescue my phone?
What I would like to ask is some form of step by step help.
I would be very grateful if anyone can lend me some assistance. This is my first android phone (yes i'm a poor fellow) and its not even a week old. I do have an AcerA500 tablet and i have been able to update that tablet to any custom variations (ever since i owned it roughly 2 years ago), so i'm pretty confident that i am good in following instructions)
EDIT:
Okay, i'm able to update the firmware by doing the following:
1. PUT "DLOAD" folder into EXTERNAL SD, root.
2. Pull out battery.
3. Stick USB into the port, and into computer.
4. PRESS VOL+,VOL- and POWER together (Reboot into pink screen)
FIRMWARE UPDATE PROGRESS. it should be 1/2 then 2/2.
"Do Not turn off the device".
AFTER finishing step 4 (it takes some time)
there will be a "TICK" and it will say "RESTARTING".
And then the HUAWEI FLOWER (no animation).
And it repeats itself....
What do I mean by repeat itself?
1. BLANK
2. HUAWEI WITH FLOWER (NO ANIMATION)
After this, there is a green android picture and says "FORMAT /CACHE" and something like that.
Then it goes blank and huawei flowr (no animation) again, and again, and again.
*NEWv2*
I can enter the the blue colored Android system recovery *3E* screen.
formatted / data reset
it has formatted all (at first cannot format cache, causes many problems, now finally fixed). So somehow I managed to format data and clear cache.
It finally reboots. It starts up. And I thought problem over. It was not.
First time boot up was okay. It asks me to set up android, etc. Second time boot up, it will get stuck in a boot loop. Help!
I'm stuck here. Any help?

I suspect the errors happen because of the fact that i installed JELLY BEAN CM10.1 v7 before, and flashed the gapps too.

I flashed the original Huawei Rom first. I know i cannot flash custom rom because the recovery is *3E* recovery, not the CWM/TCW recovery.

thats what i would do. first flash the huawei rom. start it, look that it works properly. after that i would root the phone, start again and look that all work as expected. then install rom manager and flash the cwm recovery, start again. boot into recovery, start again, always look if the phone is still working as it should. than take a good rom(aurora or cm10.1 v7) and flash it.
as often as you try it out and test if it all works as expected as early you can find out where errors come from.
only flash gapps if the rest works fine.
(which version of gapps do you try to flash? gapps-jb-20130301-signed.zip worked best for me over here)
Edit: http://www.huaweidevice.com/cn/downloadCenter.do?method=toDownloadFile&flay=software&softid=NDEyNTU=
this ist official 528 which worked very well for me. maybe 526 isnt the best suitable.

I'll suggest you to install the patch from blefish if you are using B522, B526 or B528 as rom base.
You don't know when will be helpful to have a bootloader unlocked.

at least after installing you will find the information in the area yoou mentioned yourselve.
if you use the original rom, the version should be in the filename. (U8800_Android 2.3 V100R001C00B528G001%28通用版%29.zip for me)
Wait, is your current recovery CWM recovery? If yes, try installing Aurora ICS. If no, first try rooting your phone and installing CWM recovery.

Official Huawei GB roms have 3 different bootloaders, B517, B518 and B522, the first two are unlocked this mean you easily can reach to eMMC via pink screen. For B522 bootloader that comes into rom B522, B526 and B528 Huawei changed the way how to communicate, so we can’t reach eMMC via pink screen mode. To check if it is unlocked in pink screen mode connect to PC, if you can see the folder “image” your bootloader is unlocked.
Blefish explained in his topic that you have more chances to recover your device from soft-brick if you have a unlock bootloader because you are able to restore your device with a previous full backup done with “dd” command or with a similar program used in windows platform.
Change partition size have a high risk to corrupt them and get a soft-brick.
To have more chances to recover my device I usually follow some steps before start play with roms, see my checklist:
- Install B528
- Root the device
- Imei backup (if I haven’t done previously)
- Install CWM
- Flash Blefish’s patch, alternative I use my patch because I need my phone with SIM unlocked
- Full backup (if I haven’t done previously)
- Ready to play

I think at the time of writing AURORA ICS is the most stable, usage-ready, and most complete ROM as of writing. In the future hopefully the newer ROMs like Jelly Bean, Key Lime Pie and others will be able to fit in, and be a PROPER, USABLE ROM just like how AURORA ICS and the MIUI ICS was for this phone.

Ah, i forgot about the IMEI backup. But since mine wasn't an issue (just missing serial number, but can be found at the sticker behind phone (inside) anyways haha.
For the last two weeks, I've tried pretty much everything I can think of to get my TPT booted again. Symptoms of its current illness include:
Lots of error messages when booting into CWM recovery ("E:Can't mount /sdcard" for example)
If I attempt to boot normally, I get stuck on the Lenovo logo screen.
Randomly I'll boot into CWM recovery and get its logo on the screen, and a line of text, but no menus.
Other times I'll attempt to boot into CWM recovery, and just get a blank screen
So last night I used nvflash to put a new CWM recovery into partition 6: after which I was able to boot into CWM with no errors. (Yay) However, when I tried to reinstall CynogenMod (whose zip file was sitting on my external sd card), it hung during the installation. I rebooted anyway; this time it got as far as the CyanogenMod spinning logo and hung there. I went to bed, and seven hours later it was still spinning away.
Then I rebooted into CWM (without errors) and managed to install CM ROM this time also with no errors. However, again I can't boot. I get as far as the Lenovo logo, and if I boot into CWM recovery I have all the mount errors again.
Along the way I've erased the cache; done a factory reset, etc.
So: nvflash, new CWM recovery (but still errors), reinstalled CM ROM, but can't boot into it.
Any suggestions? Has this machine packed it in - is its hardware faulty in some way? Or is there something I could try which I haven't already?
Thanks folks - I think I've reached the limits of my fixing ability, and would be very gratefiul of some advice.
Thanks again,
Al
In CWM check to see if your /System folder is mounted with read-write privileges or only with read-only. If the former, then your bootloader may have locked itself. Also, what is your device model? If you have a have a US device then it cannot be unlocked as it has been encrypted by Lenovo...
Sent from my ThinkPad Tablet using Tapatalk
Thanks - it's not a US model (I bought it in Australia, where I live). I thought the bootloader was unlocked because I could use nvflash. When I boot into CWM recovery, I can't mount /system: if I try I get the error "Error mounting /system", along with other errors about not being able to mount or open /cache/recovery/{command, log, last_log}. And since I can't mount anything, I can't install zip files.
I can't remember the device model, although I suppose I could use nvflash to trawl through the partitions somehow. (Since I can't boot the device I can't do the usual thing of checking out the system settings.)
Anyway, at the moment it won't boot beyond the Lenovo logo, even after putting on a new CWM recovery (with nvflash - but as we see above this new recovery is still not working) and reinstalling a ROM (with CWM recovery, which I managed to do on the one occasion I could boot into CWM without mounting errors). It's a right pain, that's what it is.

Well there may be hope yet as I understand (not sure) that only the US models shipped with a locked bootloader. My US model locked itself and after some research I eventually replaced the motherboard with one from eBay. There are threads around here regarding the bootloader that might have a few "options" for you to try. On the other hand I read on the Lenovo forums that Lenovo actually replaced motherboards (during the warranty period) due to failures which caused the nand to lock read-only. If the "options" don't work then the latter may be the case and you might want to consider my approach or just move on to a newer device. Good look...

I never thought of replacing the motherboard! I'm happy to try it, though, given instructions, and the correct (ROW; ie non-US) motherboard. Is it hard to do - and where can I find out how to do it? And how do I find out exactly what model I have?
Thanks for this - I'd really like to get this beastie working again.

No offense intended but you are somewhat peculiar as you are familiar with NVFlash, can determine which partitions to flash with the correct images but you don't have a record of, or can't find your device's model number? Check on your SD Card port flap (or your invoice). Then check out this page for details.
However if you decide to replace the motherboard then search eBay for "thinkpad tablet motherboard" and choose either of the 1838 or 1839 options. Any will fit and work but you probably won't get your (non-US) choice of replacement motherboard so will probably just have to get what's available.
See here for some basic dis-assembly instructions. Then just take you time and the rest will be obvious. Good luck!
Thanks for that! I tried responding earlier, but my post was blocked by the system. Anyway, I'll check for a new motherboard and have a go installing it. Do you know how I might prevent this from happening again?

No problem at all.
"I'm in the same boat": I replaced my motherboard with another US version about 6 weeks ago, rooted, installed CWM recovery and steady so far... "with fingers crossed"...
