Not possible to go back to HC that easy , see in the guide I posted , there is a link to a thread on how to.
And you don't need to flash the light version A500 rom from the guide thread as you are already on the ICS bootloader because you flashed the ICS leak.
Just so you know that 1.031.00 leak is what Acer is pushing out as OTA so you are not missing any thing.
See this line of my guide:
You can also flash the full leaked version of 1.031.00 but then you need to get root so you can delete "recovery-from-boot.p" from /system before you flash the unlocked booloader and custom recovery.
If you feel insecure better to flash full leak that way you get the stock recovery.
civato as we are talking recovery's is it safe to just flash the ICS update as a update.zip with CWM still on the tab or should i replace it with the acer recovery first?

Thanks Civato,
I manage to go back to HC which I got a back-up file in my CMW in my SDCARD ....after I installed the boot thingy V3 I regain the CMW recovery...then I just fully restored to my HC 3.2.1 com_gen2. After that I still manage to retain the V3 thingy boot & CMW recovery... Also, i got the official OTA & I'm running ICS now . Thank you so much. xoxoxooxx

Hey guys,
a friend of mine has got a problem and I hope you may can help me.
He had 3.2 on his tablet and wanted it to root. So he did the "downgrad method" an everything worked well. Then he flashed the Thor ICS Rom with CWM. Everything was fine, but he wanted to flash antoher ROM.
I don´t know why, but instead of using the CWM full backup he flashed again the "downgrade_not_stable" file.
Now he is stuck on the Android boot screen.
CWM isn´t available anymore, so he can´t flash another ROM.
Is there any option to solve this problem?
Go to settings and then about. Go to system update at the top. This should get him back to stock 3.2/3.2.1.THIS WILL TAKE A WHILE... You will need wifi as it downloads official update.
After getting back to stock 3.2/3.2.1 go to android market and install the acer recovery installer and also install iconia root, you should find both here somewhere.
THEN downgrade to 3.0.1.
Run iconia root, then acer recovery installer (puts cwm back on tab).
Install rom of choice by transferring .zip file onto sd card and booting into cwm.....
At first thanks for your fast answer.
The problem is that he is stuck on boot screen which means he isn´t able to go to any settings. After downgrade from ICS to 3.0.1 not stable, he only sees the Android Boot logo
Sounds like it was a bad rom BAD Download..

He does not have access to cwm recovery.
the op flashed a full acer ota rom.. this flashes back the stock recovery.
he has a bad rom file. or something went wrong with the downgrade..

Thank you all!
We will give this a try, even if the Rom he used to downgraded doesn´t seem to be bad. (He allready succsefully used it to downgrade and root from stock rom before flashing ics and doing weird stuff ) But maybe there just went something wrong with the downgrading process. Worth to give this other rom a try.
I have an additional question: Isn´t it possible, that there is a problem with the kernel used with the ics rom and the needed kernel of the downgrade rom?! (sorry i don´t really know about this stuff)
/edit: Ok following problem: USB debugging is not turned on and he can´t turn it on because he is stuck in boot :/
Try holding down power and - volume, when acer logo appears then rock the screen lock button back and forth once. This should clear cache and user data.
Try flashing the 3.0.1 update file again using acer recovery (you might try downloading again in case its a corrupt file) and see if that works.... Then install iconia root and acer recovery installer to root and reinstall cwm.
If this doesn't work, I'm out of ideas....

That sounds like a good idea.... nev3r knew about rocking the lock button..
Read about it lots but never tried it - never had to... At this point you know just as much about it as I do....
Thank you all for your help but nothing worked.
My friend called the Acer support. They said it should be an hardware defect (I don´t really believe it) and they want him to send the tablet to the support to replace it...
Just tell him to use the EUU tool from timmyDean's thread to flash stock rooted 3.2.1 from your PC or use the method 1 downgrade from my signature.
Oh, and he doesn't have a "bad download", and he flashed the same 3.0.1 that worked the first time. The mistake was done when he flashed 3.0.1 over thor's Asus based ROM 3.2.1 making it a mess.
Hi All,
So I'm tired of my stock 3.2.1 flipping between the "Your Device is Up to Date" and "Poor Network Coverage" messages when checking for the ICS update.
I current have:
Acer_A500_7.014.14_COM_GEN1
Through this wonderful forum, I downloaded:
Acer_A500_7.014.14_041.203.01_COM_GEN1_1333444737199_8ec8b991.zip
I found out it was encrypted, so I downloaded the Acer decrypting tool and unzipped it.
So with that said, I have a few questions:
1) Will this release of ICS work with my current device?
2) If yes, how do I update my stock 3.2.1 to ICS? Do I need to root it before I can update it, or can I simply copy the update to an SD/USB Stick and update from there?
3) Do I need to decrypt the install, or can I use the encrypted version?
Or should I simply stop being so damn impatient and just wait for the OTA?
Thanks.
Have you been back to the Market (Play Store) and installed the recent Enhancement Update to the Acer Update Readiness Tool? Should allow you to connect to those "lazy" servers.
Hello,
I just did the manual install to ICS myself that way:
1) dowload the ICS update you mentionned
2) decrypt the zip with the acer decrypt tool
3) only extract the update.zip in the decripted zip to the root of the external sd
4) shutdown the tablet and restart it pressing both power + volume dow button which start the update automatically
Ps: a good thing is that this update does not wipe existing intalled apps or existing data
Hope this helps

Thanks.....I tried it, and the process appeared to start ok. But after about 30 seconds the Android robot showed up with an exclamation point in a triangle.
So maybe this update was not for my system. I guess I'll just be patient and wait for the OTA upgrade.
(and yes, I do have the tab enhancement installed in case anyone is wondering).

Forgot to mention, just before updating to ICS, i tried to use another 3.2 stock rom to see if OTA was working better, so maybe this update to the other 3.2 rom is also necessary.

*** FIXED!!!!!! ***
I found out the SD card type is VERY IMPORTANT!!!
When I initially tried to install the ICS update from a generic SD card I would get the robot / exclamation / triangle error (I was using a Patriot 8GB SDHC Class 4 card).
I then tried using a Sandisk 2GB MicroSD card - UPDATE SUCCESSFUL!
I didn't have to use a Stock 3.2.1 image or anything - I just went straight to 4.0.3.
My new build number is ACER_AV041_A500_1.031.00_WW_GEN1 with Android version 4.0.3 of ICS goodness.
Thanks to everyone who gave me ideas and who posted on other sites!
EDIT - So I installed it, but then I had the dreaded DHCP-Wifi reboot problem. I fixed it by doing a factory reset, and all is good.

hi scuba just been talking to acer and if you get bad connection on screen they say do a factory reset but i am waiting for a good signal cause a factory reset will wipe the lot and if u have 50 odd apps then you will be in for a long haul reinstalling also the ics firmware update will be rolling out after may 1st as it was put back do to bug fixing and they wanna get u.k devices up and running with no hitch also the playstore app people insist on downloading will force close apps and the tab will go crazy and then you have to reinstall apps ect i have heard so many tales dont do it unless you want to also this bootloader root thing dont do it man it will either make the tab useless and invalidate your warranty if u still have 1 many thanks ps i will wait for the ics firmware and do a system update from the tab cya happy days

You do not need to rename anything dude, You should have installed a custom recovery if you flashed a rom already before, you go back to recovery, then go to the option to select zip from sdcard, find and select the file, that is it.
The android error screen you described is the stock recovery.
Also once you install one of the latest CWM recovery you can easily flash the bootloader.
how i can install recovery on original stock ????

This is from another thread HERE.....b4 u do anything GET YOUR CPUID - please ask if anything is not clear
You may need to root first so u can delete the file at step 2
1. get yr cpuid and save it multiple places open a file explorer and go to /sys/firmware/fuse/acer_cpuid
2. then go to /system and rename/delete the "recovery-from-boot.p" file - this will prevent your custom recovery being overwritten with the stock recovery.
3. have your custom rom on yr ext SD card, ready to flash ONCE you've flashed the unlocked bootloader
4.To flash the v8 bootloader you need to use nvFlash and there are a couple ways if going about that...
a) manually by using the guide in the OP of civato's BL thread
b) using one of the auto tools like afterOTA or apxFlash - links also in that same post...
c) you'll also get to pick a custom recovery and it will be flashed at the same time - cwm 1.7.3 is recommended until you're running stable
d) From yr cpuid - generate yr sbk - how to do that is in the same OP
5) once flashed, boot straight to recovery
6) Do a nandroid backup then the wipes
7) Flash the rom
8) Reboot to recovery and wipe again
9) Job Done!
notes:
Everything you need to do this is in civato's BL OP - sorry can't post the link but its stickied in the Dev Forum
[GUIDE]A500/501/G100W-Installing ICS V8 UNL-BL & CWM Or back to HC BL(24-6-2012)
the afterOTA tool,
- saves all yr uid details etc in a txt file
- flashes v3 bootloader -
- it also installs the needed drivers too
- its pretty good at what it does...
seems some are having wifi issues with jellytime but the dev is working on this
you've done the right thing by asking questions before attempting anything, wish everyone was like you...if my post isn't clear then please let me know....for those of us used to the way things work with our Acer, its hard to remember how difficult it seemed when we were new!!
good luck

6) Do a nandroid backup then the wipes
7) Flash the rom
8) Reboot to recovery and wipe again
9) Job Done!
notes:
Everything you need to do this is in civato's BL OP - sorry can't post the link but its stickied in the Dev Forum
[GUIDE]A500/501/G100W-Installing ICS V8 UNL-BL & CWM Or back to HC BL(24-6-2012)
the afterOTA tool,
- saves all yr uid details etc in a txt file
- flashes v3 bootloader -
- it also installs the needed drivers too
- its pretty good at what it does...
seems some are having wifi issues with jellytime but the dev is working on this
you've done the right thing by asking questions before attempting anything, wish everyone was like you...if my post isn't clear then please let me know....for those of us used to the way things work with our Acer, its hard to remember how difficult it seemed when we were new!!
good luck

thanks a million for your kind help ..
actually i am still unable to unlock my boot-loader .. and load recovery in order to flash a new ROM .. but still unable to unlock my boot-loader although i tried acer recovery to load another recovery but still unsuccessful .. i found that i can't delete the file you mentioned "recovery-from-boot.p" even i used root manager to delete it by force while it says deleted after requesting permission but i found nothing deleted the cursed file "recovery-from-boot.p" still there !!!
i am going crazy for weeks now i am just trying to unlock my boot loader in-order to flash another Rom .. but can't log into recovery always same dam android with the yellow triangle and now another curse with this file that can't be deleted !!!
just tell me how i can overcome that curse and go into recovery by any mean .. some guys tell me that i have to write some command in the lynx language to pass that war )
any advices !! :crying::crying::crying::crying::crying::crying::crying:
your root is broke
It sounds like your 'root' is broke or you havent mounted system as writable in order to have any changes stick...so
download the zip file attached to this post...ICSRoot by blackthund3r
extract the files and run the .exe - once its done REBOOT your tab
I'm not sure of this root manager you spoke of...????
Most file explorers will have a setting that enables you to 'write' and make changes to the /system partition - so make sure this setting is enabled...Superuser should pop up and ask if you want to 'grant' your app 'permission' if you don't see this then:
check superuser app is installed on your tab,
You are on the Stock ICS bootloader you cannot use Acer Recovery Installer to install your recovery....you need the v8 first ok?
So root yr tab with ICS root, REBOOT and then run nvFlash to install your recovery/BL
still unable to install another recovery

oh dear...I'm sorry you're having so much trouble flashing a recovery...
a couple if things first -
1. everytime u update to a newer version then u WILL LOSE ROOT!
2. you cannot use the acer recovery installer on ics
3. wifi on stock ics is known for being problematic
4. flashing the unlocked bl/recovery Must be done in specific order if u don't follow the steps exactly it won't work
so, you can try a complete factory reset of yr tab by using the option in settings>backup and restore....u will lose all yr data and settings - but yr wifi should work....for awhile at least....
as far as flashing the unlocked bl goes - there s a guide in my sig how to
your other option is to rollback to HC using tdv4_rollback rom a link to that is also in the guide
,
im outta suggestions but wish u luck in getting itsorted

still life is mass with that dam bootloader

Your first hurdle to overcome is to delete that file you need to delete that file that causes the stock recovery to be restored. No point in doing anything beyond getting the files you need ready and getting the Acer drivers installed.
Are you using root explorer to delete that file? You need to click the button at the top that remounts the file system as r/w, by default the file system is mounted as r/o and will not allow you to make changes.
If that does not work, do me a favor: download this root check tool from the play store:
http://tinyurl.com/d6tj85a (Play Store link to root checker basic - free app)
That utility will check that the su binary is installed and that permissions are set. Give that tool a run and report back to us so we can get you running!

You do not need to delete "recovery-from-boot.ICSRootBackup.p" the root tool has renamed the boot.p file for you not sure why you cannot delete it though sounds strange!
Go take a look here at this guide and see if it helps any: http://forum.xda-developers.com/show....php?t=2049778
If you are using apxFlash tool go to the "Bundle Market" on the first screen and choose "Bundle No. 17" this is V8 bootloader with cwm 1.7.3 theres a good guide here showing this http://forum.xda-developers.com/showpost.php?p=32905041&postcount=20

I have a Huawei u8800 pro. I upgraded it to ICS the official upgrade. I had rooted my device when it was on 2.3.5 itself.I had changed the recovery to twrp and had flashed many ROMs onto it which were listed in thus forum. Every ROM were good but always had a problem with the network. I used to go back to the gingerbread everytime because i had a nandroid backup. I then upgraded the phone to the official ICS by the method they had suggested.But I still had the problem with network so I went back to recovery and twrp was not there so i tried to put new one and now I am stuck on image signature verify fail!The pink wont show the image drive also wat should I do.....i am so desparate about wat to do...pls help me..pls reply..thanking u in advance..

the new one as in TWRP 2.8.6.0?
which version of ICS did you install B928?
if so did you:
check if baseband 404029 instead of 404020?
IMEI wasn't messed up during process?
follow pink screen unlock method?
where does it say image signature verify fail during which process?
I am not able boot the phone its....neither to recover or normal mode...the baseband was 404029..I think

If you were on B928 version, you can run pink screen unlock to install a custom recovery such as TWRP.
However if you're not able to boot, this possibly means you flashed a wrong firmware. double check if you have a u8800pro not the u8800 or u8800+ (i'm not sure about the + one) they have different firmware.
Overall if you have a u8800pro, i recommend installing the stock B928 following the official procedure, this is almost a foolproof method to fix any possible software issue you may have.
the link below should have all you need.

Solved the problem
The answer was so simple....If u want all the data present in your mobile download the boot loader unlocker from the website given above by sarsiroslayer..thx man
Paste the Update.App in folder called dload and the folder should be in the root of the sdcard...yes you need a sdcard...and then remove the battery of the phone so it switches off...then connect the phone to the USB wire without battery...and immediatly press the volume. Down,volume up and power button...so it goes to a pink screen..and remember the sdcard should already be placed in the phone...and yes if the phone does not go into pink screen and instead starts to update the software Olla ur phone is fixed......restart and all will be fine...
Ifthis did not work or u don't want any data download the official 2.3.5 android from the huawei site and place the update.app in dload folder and do the same thing as above....My phone is working..:highfive:
Remember remove the battery...before updating ....
Thx all for ur support..xda rocks...
I have typed the solution so even a begginer can utjnderstand...

If you are rooted with Custom [ twrp,Cwm , what ever ] recoveries then you will not be able to do an OTA update . You will either get stuck in boot loop or recovery loop .

man just install twrp recovery and flash stock rom. then re-install your stock recovery, should get you fixed. don't forget to remove root also before making the OTA update.
