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

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.
forumber2 said:
In Blue screen,connect your phone to PC and wait 1 minute. A storage will show if you was in B518 bootloader. If the storage shows,please report here

Click to collapse
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:

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:
http://forum.xda-developers.com/showthread.php?t=1457490
I quote Blefish:
Blefish said:
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!

Now that you've fixed the locked bootloader on 522/526/528, now its time to do the partition. zip

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.

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?

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)

this ist official 528 which worked very well for me. maybe 526 isnt the best suitable.

Wait, is your current recovery CWM recovery? If yes, try installing Aurora ICS. If no, first try rooting your phone and installing CWM recovery.

Question, how would I know my base ROM? I have read the thing, but there isn't a way in my status to know that its a B522, B526 or a B528 based ROM.
Answer: Look at the code of the installer:
E.G:
U8800V100R001C00526G001 means I have base 526 installed (LOCKED BOOTLOADER)

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.

Ok, so I have a Droid X2, and the Droid X and Droid 1 as predecessors. I have never had any major problems, and the few that I couldn't get around I had SBF via RSD for. To my knowledge, there is no form of SBF for the Acer A500 (yet). So heres the issue:
I may have either flashed an update without the proper files to go before it; or I have have forgotton to wipe something. Nonetheless, my A500 wouldn't boot. When I did some research, I went to this site:
{http://forum.ppcgeeks.com/showthread.php?p=2127076#post2127076}
because it seemed in my eyes to have the most pertinent information. I got the update.zip to install and my A500 booted again! However, I could not get to stop two because my insternal SD card was wiped somehow and when I get to the main screen, do the circular unlock, the launcer, and many other programs repeatedly force close, so much so that I cannot do ANYTHING. How would you approach this, and is there a way for me to get into CWM. I have a recent nandroid backup that what 100% functional, and I would hope the MD5 sums would still match....
Any help/advice is greatly appreciated!

The top link provides a way to install via Acer recovery the new 3.1 OS, but to my understanding its unrootable for now, is that still the case?
the update zip is uploadable even without root.
just like the original OTA firmware. Try it, many other users got back their pads with this one, as you can see in internal posts of the thread

I totally get what you're saying. What I meant is that if I did the update, it completed successfully, that I would then NOT be able to root the device. Obviously that is a better option that a brick! But I'm trying to find out if I can recover to the most updated version that has been rooted.
Maybe I'm wrong and a root program has been made for 3.1?
hey mate, U quite a little lazy readinf threads titles uh...
take a look at this http://forum.xda-developers.com/showthread.php?t=1138228
pick up the 1.3 version. it will root your "definitely final" version of os, this update U have just uploaded IS the last one available, and it's eligible of any further OTA update...

I work 70+ hours a week, I'm certainly not lazy. But that is why I ask these questions hoping for someone to give me a little short cut to the answer. Between work and sleep I have 2.75 free hours a day and do NOT want to spend them reading a forum where its a lot of bs banter in between the actual info. I'm sure there are a lot of people out there that just don't read, but I truly don't have the time.
Also, this is one of the biggest forums for Android out there. Theres no way I could ever read the HUNDREDS of threads just on this device alone....
I do appreaciate your help!!!
I'll give a final report when I have a chance to do it!
This method did NOT work. When I boot into recovery, it always goes to the screen with the triangle and the android. I never see a progress bar....does this matter?
I also tried your other suggestion of "wipe device without recovery" and that didnt work as well.
I know its not a lost cause since it boots all the way up. But every app force closes so I have NO access
YOU have to do things in proper steps !!! ( lack of sleep will do that to you ! )
1/ grab the file from that thread
http://forum.xda-developers.com/showthread.php?t=1159443
( remember to unzip it to get update.zip file and placed on your card and flash using normal recovery.... not renaming ! )... assuming you don't have CWM at the moment.
2/ grab the "iconiaroot 1.3" file to root your device ( as CWM and Acer Recovery Installer required root access )
3/ grab the Acer Recovery Installer and proceed to install CWM to your device...
after all those are done... work your way with CWM ( to access CWM ... you need to keep holding the buttons (Power & Volume down) until you see 4 lines of text...and not let go before that !! )
remember to wipe cache & factory reset ( both before and after to ensure 110% cleaned to avoid errors and FC )
good luck !!

So I responded to this last night, but somehow it disappeared?? Anyways, thank you for your effort to help me resolve this, but if you look at my initial post, there's no way your description and process would work. First of all, the update above I tried (like I mentioned) and it did NOT work. Also from my description I mentioned that when the tablet does boot, it boots to the home screen (stock green) but, all the important applications, the launcer included, force close so rapidly and repeatedly that I can't do ANYTHING. Thus, I would obviously NOT be able to install any programs, let alone root the device.
Thus the name of this thread....

And obviously you are suffering from lack of sleep !!
The update.zip ( after extraction ) from that thread can be flash either normal recovery or CWM recovery.
and here's the added tool to wipe without a recovery:http://forum.xda-developers.com/showthread.php?t=1132760
Therefore... what's stopping you ??
and please re-read my steps above.. after flashing... you will need to root and re-flash CWM using ( Acer Recovery Installer)
maybe you're not clearly looking at the picture...
there are 2 recoveries ( normal Acer stock recovery and CWM recovery )... DO NOT mistake Acer's stock recovery for the program called Acer Recovery Installer.
what Acer recovery Installer does is install CWM recovery for you and also backup/restore your original Acer recovery.
and you cannot use the program until you are rooted ( step #2 above )
FYI ... each recovery boot differently !!
Stock recovery -->> hold Power & volume down ( closest to the power button ) until some text appear 2-3 lines )
CWM recovery invoke differently.... ( hold Power & Volume down until you get 4 lines of text... do not let go anytime earlier then that )
~~~
extract that update.zip file ( my guess is this is where you went wrong... you didn't extract ? )
when you extract... make sure only the update.zip is put on your MicroSD card ( format FAT32 ).... no sub-folder...etc
Then insert into device and use the stock recovery method above.
if all else fail... get a different microSD card !!
then follow steps #2 and #3 from my previous post .
again... what's stopping you ??
I did the steps that E.B. recommended initially (directions followed religiously). Then I did what you posted (twice now,again, religiously - and yes I know how to, and properly extracted the update. !). Furthermore, I also tried a totally different SD card. 8gb pny VS 16gb San disk.
i am getting the tablet later this week. And since its the same as the advent vega i am hoping to flash a custom rom that supports market and .. well.. better..
i have rooted my HTC Desire Z. But i needed a guide. i guess i need the same with this project.
could someone help me out with something like that. atleast a point in the direction of how..
thanks
Well the way I found the best and easiest for me was to root it with Z4 root (you can find it easily here on XDA forums). It supports Advent Vega tablets and it worked for me like a charm... rooting was done in seconds.
Prior the flashing operation I recommend you to purchase ROM Manager app and use that for the installation of clockwork mod and later for flashing custom ROMs as it is the easiest and most safe way IMO. I'm having this tablet for two days and I've already flashed several ROMs using that way. Of course, I highly recommend you to backup your current ROM just in case. And guess what... you could do that too using the same app
Happy flashing and enjoy your tablet. It's great value for money!
It's reallyyy simple! I did it myself last week with the PoV Mobii..
- First, shut down your tablet.
- Download the recovery mode drivers for your tablet here: http://www.myadventvega.co.uk/SystemUSB.zip
- Extract the files to a folder on your pc.
- Now, connect the tablet to the pc with USB and bring the tablet in recovery mode:
1. Hold the back button 1 second.
2. Press the power button 1 second, but still hold the back button as well
3. Hold the back button 1 second more.
- Now, go to Configuration Panel -> Device Manager, you'll see a device called APX
- Click to update the APX Device drivers with the drivers you extracted a few steps before.
Now the tablet is ready to flash..
Download an arbitrary rom, (I have this one: http://forum.xda-developers.com/showthread.php?t=1221336, search this topic for the exe-version of the Build 9 without updates) and execute the file. The tablet should be updated when finished..
please ask questions in the general section. This is for development only. Thanks!
Mods please move this to general.
Take it easy.
cant seem to find the exe version without updates.
unless its the one mentioned in the first post:
And the last file:
Download VegaComb HC3.2 9b Installer.exe HERE!

No. But you can install 9n throught CWM. Just remember to flash modded stock v2 first.
Firstly: Copy the main build and update file(If available) to the memory card inside the tablet
Make sure the main build is in the following format "Build.Zip",
Make sure the "Update" is in the following format also "update.zip"
1) run first nvfalsh Modded Stock v2,
1a)Boot-up and conplete installation, Reboot Twice
2)Now select Recovery in Applications
2a)Once you are in recovery, wipe Data, Cache and Dalvik. Select Fix Permissions.
3)Now select Install Main Build zip file form SD card
3a)Select Choose zip file from SD
3b)Select the Build 9n zip file
3c)Wait for it to complete installation and re-boot.
4)Boot it on and power down a few times to make sure it works.
5)Use the shut-down Menu to select Recovery.
5a)Tablet switches off and tries to boot-up, but hangs with a backlit screen.
5b)Press the Power button for 6 seconds to completely switch off the tablet.
5c)Press Power button to boot-up and wait patiently - CWM recovery WILL start.
6)Now select Update file from your SD card
7)After Install,Re-boot
Well... Seems like we've got ourselves a new bootloader, after flashing the BETA1 Gingerbread for U8800. Not cool...
I tried it and didn't like it.
Furthermore, I wanted to keep my device in that zen condition which allows me to return it to my carrier under warranty.
I've tried to revert to my carrier stock ROM, but to no avail. I can run froyo alright, but the carrier costumizations are simply ignored, courtesy of the new bits that came with Huawei's beta.
Some time ago, and antecipating something like this, I connected the mobile, while in pink screen mode, to a linux box and dd'ed the entire volume to a dump file. I can mount this dumpfile through /dev/loop and confirm it carries the same partition schema that is present in the mobile. I'm tempted to dd it back to the mobile, to restore it, but affraid of bricking it for good. If bootloader gets invalid then nothing short of a factory j-tag flash will solve it, for sure.
Has anyone done this before?
Thanks in advance.
EDIT: It worked. The whole volume was restored (bootloader included, naturally).
Greetings,
Everything else aside, claiming that the installation of a manufacturer released upgrade (yes, even one labeled Beta) automatically voids your device's warranty pretty wild. That's not to say that someone somewhere won't make that argument, but there are plenty of crazy people in the world.
That said, good luck.

is the dump file around 4gb then yes it will work I did it my self through restoring raw sd image
Sent from my u8800 using xda premium
By the time I red your reply, my mobile was already back to Zen state. Thank you nevertheless.
On a side note: the battery was very low by the time I initiated the restore, but since it was connected through USB, I assumed it wouldn't be an issue.
It took around 45 minutes to restore the image and when finished, the battery was exhausted to the point that I couldn't turn the mobile on. Thought I had bricked it for good...
Charged overnight and everything was fine and dandy.
Cheers
mine took 25min
I managed to downgrade to 2.2:
Get some 2.2 update, mine was b136.
First tried to update from sd card, it failed. Then tried from the internal SD and it worked (Take off the external SD first). But the update was too fast and it only booted to original recovery (with some warnings). So i did the update again and now it toke the usual time. But it it still only booted to original recovery (with some warnings). Then i did a factory reset from the original recovery, and voila, it booted to 2.2!
Once the 2.2 was booted, i copied CWM recovery in the pink screen and it works now too. Then i was able to install Miui again.
straight restore did not work for some reason, maybe needs to format everything first?

Yes, I had it running FROYO back too, but the phone's condition wasn't the same as before.
If I understood it correctly, the 2.3.5BETA rewrites de boot partition - the 2nd primary parition on the device, marked bootable. This becomes obvious when the "IDEOS" logo is replaced by the "HUAWEI" one during device boot-up.
The partition scheme is the same as before, however, as I had the chance to confirm.
Flashing a 2.2.1 ROM from Huawei did not write the old bootloader back, furthermore this might not be the only change.
I was able to revert to an overseas 2.2.1, both through CWM restore and "dload" method, but carrier customizations were always absent.
Along with the regular system, my carrier's ROM adds a batch of apps, ringtone, wallpaper, binaries and libs, under "cust_data/tmn/pt". These were all ignored. Not that I cared much for them, but as I stated in the original post, I wanted it back in the original condition, as TMN will consider warranty void if the device has been tampered with.
Since I had a raw dump of the volume I restored it back and got my mobile as it was some 3 weeks ago... To my relief...
Can you please make a tutorial to make and restore raw backups?
1. Step : Download a official 2.2.2 rom
2. Step : Put the dload folder at the root of your sd-card
3. Step : Power your device of and boot into bootloader by pressing volume +, volume - and power (before you do that, you can do a titanium backup)
4. Step : Wait till the prozess is done. When your device doesn't reboot by itself, reboot it manually. (if there are any problems with the rom, wipe cache and date with the original recovery)
5. Step : Download a CWM recovery. Boot your device like the same way above into the bootloader. Rename the CWM recovery you've downloaded before into recovery.img
(6. Step : Rename the recovery of your device in the folder (device):/image into recovery.img.orig, to do a backup of the original recovery)
7. Step : Put the new recovery.img in the folder from above. Unplug your phone from the PC and put the battery out to turn it off. Boot it into recovery by pressing volume + and power.
Congratulation, you've restored your Ideos X5 to 2.2.2.
Now you can download a custom rom and install it by the normal way.

Hi,
I try to downgrade my current A500 on HC 3.2 to 3.01 with any success.
I follow to tutorial based on "Vache" tips available at http://forum.xda-developers.com/showthread.php?t=1276227
I have done all the step, but when i launch PBJ20upgrade.exe as administrator, it ask me to plug again my iconia, it display the current installed version and version who will be replace, click on "Next" button and... progress bar doesn't move.. the iconia switch off (black screen). I have try many times and always the same result.
My current configuration is :
Kernel : 2.6.36.3+ - build : Acer_A500_7.006.01_COM_GEN1
My computer is on Windows 7 64bits.
Any ideas ?
Have a nice XDA Christmas.
Method 1 can take up to 10 minutes or longer to get action. Perhaps you didn't wait long enough.
Try Method 2. It's even easier.
Not sure if it matters, but set your USB Debugging to on. Settings/Applications/development
USB Debugging is set to on.
When you said "Method 1 can take up to 10 minutes or longer to get action." it's mean before seing the progress bar moving ?
In any case i will check method 2 but just a little bit afraid with the " gives errors and crashes but you only need it to root and install CWM"
One small question, with STEP 2, it will replace the current HC 3.2.1 by an unstable 3.01.
Let imagine after the procedure (root + CWM) i would like to put a ROM STOCK as my iconia was delivered, i think it's possible no (and where to find it because i have no img of my current version because not rooted).
And if i do it (install rom stock) it will be updated to HC 3.2.1 with OTA no ? Root and CWM will be lost again in this case ?
Thx for reply.

No Problem. Remember, sometime, systems will reboot. And sometimes, you have to wait. I cannot tell you that this is happening with your case. But, it is best to wait some time.
Both methods, I believe, will give you an unstable version of 3.0
Yes, both methods, will replace the current operating system. But, between errors, it will allow you to run the iconia root, and run the acer recovery. I don't think anybody has failed to do this, except for idiots who can't follow instructions.
I would suggest you download these, and put them to SD before starting the procedure. It saves having to get them from the net. Also, go ahead and download a rom you want to try. Might as well do all things at the same time.
True, basically, you will be without a stable recovery. Which is why, after you install Acer recovery, and install the recovery part, it is necessary to make a backup of the current system. Better an unstable one, than no system at all
Then, do your boot to recovery, system off, hold vol- and pwr till you see the text in the top left corner, then release.
Nav is by the vol - and +. Pwr to select an option.
Wipe;
1. User data
2. Cache Partition
3. Go to Advanced, wipe delvak cache
Go back to previous screen, and select Install From Zip, choose zip to install, and select your rom
Wait 10 minutes or so.
Now, when the rom boots, and it will, if you get several error mesages, then, you should reboot to recovery, only this time, goto mounts, and format the partitions. Usually, you don't have to do this. But, sometimes, traces of the opld rom remain behind. But, I think you will be ok with the previous procedures.
And, you're a good boy, as you ask questions before you do things

Hi again,
Sorry but i have a stupid question. Based on solution 2 for downgrading (by using a SD card) if it's so simple why we don't use it to flash any ROM like Thor or Tabonnay ? just by placing the "update.zip" file on the SD card and boot on recovery stock ROM.
I understand that "rooting" a tablets allow to have full access on it (all partition) but why it's necessary to replace recovery tools by CWM ?
Sorry for this stupid questions but i love to understand what i'am doing.
Hi again, so i have done the downgrade with step 2 but have some issue.
V 3.0.1 is installed and iconia root 1.3 too
concerning "itsmagic" where to get it (when i should put adb push itsmagic /data/local)
Second, for the second part of tutorial http://forum.xda-developers.com/showthread.php?t=1126364, i need to type some bash command on the tablets, but how to ?

Hi again, so i have done the downgrade with step 2 but have some issue.
V 3.0.1 is installed and iconia root 1.3 too
concerning "itsmagic" where to get it (when i should put adb push itsmagic /data/local)
Second, for the second part of tutorial http://forum.xda-developers.com/showthread.php?t=1126364, i need to type some bash command on the tablets, but how to ?

Easier to download Acer Recovery from the http Market, and install it on your tab. Then flash the Thor Recovery.

Hi again,
Sorry but i have a stupid question. Based on solution 2 for downgrading (by using a SD card) if it's so simple why we don't use it to flash any ROM like Thor or Tabonnay ? just by placing the "update.zip" file on the SD card and boot on recovery stock ROM.
I understand that "rooting" a tablets allow to have full access on it (all partition) but why it's necessary to replace recovery tools by CWM ?
Sorry for this stupid questions but i love to understand what i'am doing.

To make a long story short, it won't work.
Basically, the OTA updates have a special script to run, also, they update the bootloader of the tab, which of course is more or less off limits to use poor people Not to mention the updates are "officially signed" by acer, to allow this method. And I am just guessing on this, but probably pretty close.
Anybody else have anything to add?
I suppose, a lot of time could be invested in creating a custom rom using this method, but it seems more simple to use the "recovery" method.
So it's mean that i don't need CWM and itsmagic but just "Acer recovery" ? i can cancel this part on STEP 2 ? :
5. then install CWM from thor's site (there you can find the latest version) or use Acer Recovery Installer from the Market, or look at the original thread here
6. Boot into CWM and flash whatever ROM you like!
The main problem with the market, i can connect but each time i use the tab keyboard i get an error message as describe on the unstable HC 3.01, is there a way to have an APK version (i can upload it on my microSD card).
Thx a lot.

Yeah, that keyboard is a killer and causes a lot of issues. I heard where if you mess around with the keyboard settings (a lot), it will actually settle down and work with few errors (but looks bad)
Yes, skip the adb stuff
Use your computer to access the android market web site. Search for acer recovery
Download, put it on your sd for your tab, and install it using any file manager app. Then start the app, and install the Thor Recovery. You can get Thors recent recovery later, so it's not necessary right now.
Acer recovery is a tool that makes it easy for people who do not know how to use adb.
If you can't get it done that way, then you'll have to use adb.
The directories specified in the commands, are the locations they will push the files to. The img to the sd, and the it's magic to /data/local
Never used it myself, so I am not so sure where you are supposed to place the files to begin with. I would guess in the same directory as adb.
Thx for help, when you said "Then start the app, and install the Thor Recovery", Thor Recovery is included on the A.R.I apk file if i understand well but not the last version.
2) I donwload a ROM like TABOONAY or THOR on my microSD card
3) Just after, i reboot on recovery mode by using A.R.I
4) From CWM i select the image located on my microSD card to flash my tablet
right ?

Ok, AFTER, you run the acer recovery, install, start app, and install the recovery. Should be the only choice you have
After it does it's thing. Then power off. Then, hold Vol - then PWR button, until you see text in the upper left corner of the tab, then release both buttons.
It will boot to the recovery menu.
Now, it's ok to copy the rom you want to use to the sd before doing all this. No problem.
With Taboonay, I would look at the procedure, as I believe you have to have 2.1 installed first, before upgrading to 2.2. (not sure why he decided to do it that way. Seems like a pain in the neck. I used to run 2.0 for awhile.
Harkon, is also a nice smooth rom.
Thor's V14 is also good (a500 only)
Then, very important. When you boot to recovery, go ahead and make a recovery image of your current rom (yeah, so it's unstable). Always most important to do this, as sometimes, a flash can go bad. Not often, but, better to have a recovery image to go back to, even if it's unstable.
Next, do your 3 wipes. No, not the toilet
1. User data
2. Cach partition
3. Go to Advanced, then dalvek cache.
After it's done, then, you can go back to the main menu, and select Install zip from SD
Then select your rom.
It takes awhile, so have a beer
And ... MAKE SURE you have at least 60% charge on your tablet!!! Before doing things.
People forget, and,,,, it ain't pretty...when your tab shuts down in the middle of a flash.
Nice, totaly clear for me right now. Many thx to you
And to finish, 3 last question (next beer will be paid by me of course )
1) If right now, at my current step (only donwgrade done to 3.0.1 at this moment) i do a factory reset on me main menu of my tablet, what version i will have ? Current unstable version or my previous HC 3.2.1 ?
2) When you said "Ok, AFTER, you run the acer recovery, install, start app, and install the recovery." by install the recovery you mean CWM provide on the A.R.I, there is a special menu on ARI to install it or it will be installed automatically during ARI APK installation ?
3) When you speak about "and select Install zip from SD" the ROM should be on the internal memory of the tablet or on the external (microSD card) ?
One thing that i don't understand yet is the internal structure of the partition on the tablet. As i understand, for the moment i just made a downgrade from HC 3.2.1 to 3.0.1, but we have the possibility to do a factory reset, so i think when we do that, the iconia will restore an img file or iso file from a specific partition.
So if i understand, on my current state, if i do a factory reset as usually, the HC 3.2.1 will be replaced no ?
In any case, thx a lot for time spend by you to explain me all this... this is the Russian POWER

1. Do not do a factory reset. Honestly, I do not know what will happen at this point.
2. The Acer recovery, comes with Thor's recovery program. I think, that is the only one that comes with it. Technically, you can use it to flash roms, but, I advise using the recovery built into the tab afterwards. Usually, this program will go away after flashing a rom.
3. Always in the "root" of the SD (the first file you see when you look at your sd with a file manager).
4. If you're in Moscow, I will take that free beer
Not sure exactly what will happen when you do a "factory reset" I would suspect, the same OS your device came with, but I really don't know. Never had to do it. And, I see a lot of issues when other people try it.
so, today i have installed Rom Stock, Thor and Taboonay... all those has been tested and at the end Taboonay has win (Thor is pretty good but the fact that tab is detected as ASUS is not so good for me).
Many many many thanks to you Moscow Desire for you help concerning this, all is ok for me right now and more clear.
last question, if i want to update current version of CWM (provided by ARI) how to do it ?
I have download "update-recovery-thor2002ro-rev1.3.4.zip" i think i should use CWM itself (on recovery mode) to update it ? right ?
Have a nice christmas !!!!!
Good work. Glad things worked out for you!
I've been lazy, and haven't upgraded my recovery, but I believe you just place the Thorupdate.zip on the SD like you did with Taboonay, and boot to recovery, and flash just like your rom. But really, I haven't done this yet. Maybe this weekend.
Shouldn't be any need to do wipes.
Also, if you want to run a different Kernel on Taboonay, Then you need only to wipe Delvik cache before flashing it.
Merry X-Mas to you as well, but here, we celebrate New Years.
I know it for christman, i work sometime in Russia (near Moscow). Normally for you it's hollydays since yesterday, very lucky people in Russia.
Happy new year to all XDA members !!!!
FYI - if you do a Factory Reset with the unstable 3.01 rom installed, it puts the CURRENT OS back on, this being unstable 3.01. You have COMPLETELY replaced the other OS. This will happen whether you are running a custom OS, or official OS.
You can only have one OS on your tab at a time, unless you do the dual boot but that opens up a whhole new can of worms...
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.

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

No, It was off... Everything is fine now... uff, what a relief! Glad I was easier than I thought it would be ;D
EDIT: partition table seems to be fine in Ubuntu, I guess Windows or that particular partition program wasn't reporting partitions correctly...

thanks
i flashed after this the mobile never boot
i have froyo 2.2.1 and the computer never see or even read my mobile

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.

U sir, deserve a lot of thanks for this.. I've been holding back to flash the new 2.3 ROM because its locked bootloader.. With pink screen back, flashing roms it back to getting less risky now.. TQ~!

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.
