hii to all!
i got new Acer A500 HC3.2 - build: Acer_A500_7.006.01_COM_GEN2
it never been rooted or anything.
actually i want CM9 on it, but first try to root it.
so i copied to sdcard "update.zip" (back from 3.2 to 3.0.1) boot with PWR+VOL- and it seems to think for a while and then restarted.
after the restart i saw that the original 3.2 still there.
am i doing somthing wrong ?
or its something with GEN2 or i donno what.
PS - i just see my a500 is not OTA version - its 3.2 but not have the ability to update from network.
is there any chance to do something ? PLEASE.

Hi all! My A501 16 GB had already installed Android 3.2 when I bought it. Initially I was thinking that maybe somebody updated it before I got it but now I think the tablet was factory shipped with 3.2. I followed different guides on how to downgrade to 3.0.1 or 3.1. People are reporting that they are able to downgrade after a too quick update to 3.2 without root. But on my A501 nothing seams working. I can install rooms from A500 with Android 3.0.1 and 3.1 but after the update the tablet restarts and right after starting only a red error message "Boot verified failed …" with the ACER logo in front, I consider this a bricked. Some other rooms I can't even install, the process stops before installing on the message "Booting recovery kernel image".
I am always able to repair my A501 with the available room of Android 3.2, but without downgrade I am unable to root. I am very disappointed because one week before I bought an A501 32 GB for a friend and that one was shipped with 3.0.1 and there was no problem to root it.
Currently I am convinced that my new A501 has a different boot loader which is not allowing me to downgrade or rather start another version.
Any help would be much appreciated! Within these circumstances I could buy an I-Pad also!

No root is available for stock 3.2 far as I know.
There is more A500 than A501 Users so I think there will a root for the 3.2 version after the official upgrade of the A500.
I have the same problem with my A500.
I tried to get back from the Official 3.2 back to 3.1 as I need root also but now have "boot verified failed" and can't load any other roms on there, including the Chinese one that everybody was using to un-brick their A500s.
a501 3.2
Hi,
There is no android 3.1 for the a501, only the stock 3.0.1 and then the latest 3.2
You need to downgrade to 3.0.1, root the a501 using iconiaroot and then install any of the various 3.2 roms out there.
You need to download Acer_A501_1.309.02_COM_GEN1_SD_update.zip
Just google it and you can get it from the filesonic link.
Rename it to update.zip, stick it on a microsd card and then restart the a501 holding volume up + the power button.
This should install the stock 3.0.1 and from there, as stated above, you should be able to use iconiaroot to get root access and then reflash with any of the various 3.2 roms.
Have fun.

Thank you, your help is very apreciated. I downloaded the rom and was able to install it but I ended up as many times before with other romes. After start instantly the message appears "Boot verified failed ...". Since this is a GEN1 version I fear I need a CUS7. Any Idea where I could get 3.0.1 for CUS7? Thanks!
Ok,
Try updating to 3.2 again using Acer_A501_0.000.00_4.017.03_EMEA_CUS7 (you need to google it, i cant post links as im new).
Once you are successfully booted into HC3.2, factory reset the a501 by either going to privacy - personal data - factory reset.
Alternatively, you can try the other factory reset method where you:
1. Switch off
2. Press Vol-up + Power
3. If display goes on: Release power but hold vol-up
3. Toggle Lock switch (On>Off>On>Off)
Screen will display:
Erasing Userdata..
Erasing Cache..
Then get the Acer_A501_1.309.02_COM_GEN1_SD_update.zip file and rename it to update.zip, out it on the root of a clean microsd card and start up your a501 holding the power button + volume up to install the stock rom.
This is the process i used to downgrade when i upgraded to 3.2 and realised there was no root access and it works fine on my a501.
Let us know how it goes.

I followed your advice but with the same outcome "Boot validated failed ...".
3.2 is using a new bootloader that itsmagic doesn't work with. For now, you'll have to stick with stock 3.2 (if it's still working for you). You cannot root these devices yet and you cannot downgrade them either.

3.2 is working. I'm always able to reanimate with 3.2. Thanks anyway!
Solution
Finally the solution is here: [TUT] Revert OTA 3.2 back to 3.0.1
Hi all,
I have an old Acer A500, with OTA 3.0.1...
The device does not upgrade the Honeycomb to 3.2 or even to 3.1 automatically.
I noticed that the device is rooted - Although I bought it from a shop, I noticed that it seems to be rootable - I succefully did "su -" on my Acer terminal emulator.
How can I know if the device is using a custom ROM? and how can I install \ root to another custom ROM with honeycomb 3.2?
Thanks in advance.

Currently if you wish to remain rooted and run 3.2, you'll need to flash this ROM:
http://forum.xda-developers.com/showthread.php?t=1290318
If you're rooted, chances are you'll have CWM installed as well.
Turn off your tab. Hold volume up and power button until you see a few white lines of text in upper left corner of tab, it should boot to a CWM menu. If it does, you can flash any ROM you like
RE:
Hi kjy2010 and thanks for your reply.
As I'm using Revolver \ Prime on my Asus TF, can I get a ROM of those 3.2 to the Acer?
I don't know which recovery application installed in the tablet... :|
I own an Acer Iconia A500 US Wifi from Best Buy.
I upgraded to 3.1 through an ota, right after the upgrade, I flashed one of the Gtab 10.1 ported roms. I wanted to get to 3.2, so I tried to flash Taboonay 2.0, but I got a blank screen. I managed to get in recovery, and flash back my older, 3.1 Gtab rom.
I need your help, since I don't know what to do.
I need an upgrade path to 3.2 if it is either going back to stock 3.1, or 3.0.1.
If I can flash a 3.2 rom from a 3.1 rom, I woud want to know how to do so.
Thanks for reading. Need help.
Oh also, I'm currentley having a problem with my sd card, for some reason it took out my external_sd folder and made an sd folder in storages, where I can put thing and it puts them in my sd card. When I plug in my Iconia to my computer only the internal storage autoplay comes up, would going to 3.2 fix this? Thanks so much.
bump please reply, I need help.
You should be able to use the downgrade tool from ACER which actually flashes stock onto your device. It loads 3.01 (if I recall) and from there you can upgrade to where you want to be. Search for DownGrade 3.0.1 ACER, you will find it here in the forms. I've used it a lot. I also modified a version of it to flash in 3.2 which you'll find here in the forums too.
Good luck
Sorry for the bad English, but I have a problem:
I had HC 3.2.1 and then I tried to update to ICS 4.0.3 but I mistakenly put the Iconia A500 (Acer_AV041_1.054.00_WW_GEN1) so I lost the ability internet via SIM card.
I've tried various things ... I was rooting it but I could not get a recovery or fastboot!
Now I'm lost and communication between Taba and Flash Tool or AfterRoota 1:09 because my laptop appears to me there are two androids???
Praying to someone who knows and who has the will to explain to me as simply an operation so that I could return some custom or stock rom from A501
hi xda-ders
this is my first post , and i've been re-directed here to ask questions about my acer a501. so i've had my a501 for 20 months, before it suddenly developed the well documented issue of mainboard memory failure which cannot be fixed by software. i returned my a501 to acer nz to be repaired under warranty, and they replaced the mainboard. unfortunately this mainboard was also faulty with no wireless, so i had to return it again for another round of repairs.
i finally got my a501 back on friday, and realised that the mainboard replacement was on android 3.2. previously i had upgraded to android 4.0.3 using the acer iconia tab update app, but this doesn't seem to work anymore.
1. when i do a settings - about tablet - system update check, i get the message "network coverage is currently poor. please move to a location with better coverage to continue." googling this i find that acer no longer does OTA updates and have shut down their servers so i can't do it this way.
2. i called acer nz for support on upgrading to 4.0.3. they directed me to the acer nz support website where apparently i can download the update.zip and install it manually. following the instructions exactly, i can't get this to work and keep ending up with the android robot with a yellow ! icon.
can somebody help me with the steps needing to update android 3.2 to 4.0.3 manually? i've tried searching the web and xda but many of the threads are quite old from 2 years ago when ics was first released. thank you
my tablet info:
model number = A501
android version = 3.2
baseband version = Cust:R3C01 Config:R3S/3 Conf:R3C01 Protocol:R3B01 App:R3C01
kernel version = 2.6.36.3+
build number = Acer_A501_4.031.24_COM_GEN1
Did you try to update with a 2gb micro sd? The standard recovery doesn't recognize "big" micro sd., from what I saw.
One thing: I'm not 100% sure you can update your tablet without updating recovery too. Just in case, retrieve the cpuid of your tablet, it could be helpful if it goes in boot-loop!!
Same request but different scenario
So I have Acer A500 currently running Honeycomb version installed by tool "tdv4_rollback_rom". This tool helps you to get on with valid cwm recovery and rooted honeycomb rom. I assume this brings me to HC bootloader, which is not compatible with any ICS ROM. So if I understand correctly, I will have to upgrade to unlocked V8+ ICS Bootloader and from that point on flash ICS ROM (Lightspeed or Tabooney...). If my understanding is right, I am following correct guides to get unlocked ICS Bootloader on tab using AUTOMATED A500APXFlash tool. Everything goes fine and I do get PASS screen at end. After reboot, I boot in Skrilax V8 bootloader and then boot into recovery to flash ICS ROM. After flashing any ICS ROM, I am expecting my tablet to boot into corresponding ROM but after booting into primary kernel message, I am stuck at boot logo (acer, green droid based on ICS ROM I picked). No matter what I do, I can't pass this splash screen.
So far, I have tried bunch of things,
- tdv4_rollback_rom tool
- Afterota (to flash custom recovery and bootloader)
- APXManager to get unlocked ICS Bootloader V9 on tablet (Automatic and Manual as well). This has ran successfully (PASS message) multiple times, while there were times where it got stuck in second stage of uploading.
- At end, I have tried BabSector, "a501 A.bat" ran successfully, Booted in recovery formatted System (twice), While running "a501 B.bat" (in APX Mode) as following step, I got error message "bootloader status: Bct Write Failed (code: 22) message: nverror:0x42008 (0x6042008) flags: 0"
Anytime, when I am stuck in APX mode (while doing any of the above mentioned steps), I run back to tdv4_roolback_rom tool to get proper recovery and HC rom running on tablet.
So is it partially bricked or I am following some wrong steps?
Any suggestions to fix this issue? Or I should keep HC running on tablet? I am open to run pure ICS stock as well with stock recovery and bootloader, but darn thing won't pass the boot logo.
Thanks

actually i tried updating with a 1gb microsd but it didn't work. i have 2gb and 16gb cards at hand, but neither of them works so i don't think it's the microsd that is the problem.
how do i update recovery? i'm happy to use other types of recovery if i can get to 4.0.3 but so far all my reading hasn't showed any full factory acer rom that i can flash. :crying:

In the old times (a couple of years ago) I managed to update my Acer A500 from 3.2 to 4.0.3 (the leaked one from Acer) without installing another recovery, but maybe for the A501 the things are a little different.

in the old times on my previous tablet, i updated my a501 using the OTA check update app from within the tablet. i assume that is directly from acer, however it seems the servers have been shutdown and therefore i can't use that method anymore. hence why i'm asking if anyone here on xda has the full 4.0.3 that i can use to overwrite 3.2 version.

I know, I know, no more OTA from Acer. Have you taken a look here? There's a leaked ICS rom there...

cool thanks for that link. i have downloaded the ICS rom and opened up the zip file, it doesn't look like a normal update.zip? what does leaked rom mean, not original from acer?
i'm worried that i might brick my tablet since i'm new at this flashing thing.

"Leaked" means that it comes from Acer, but it's not official (maybe it was a beta, maybe not, I don't know). From what I read, you only have to follow this flow chart in order to install it. Remember to save your data before flashing, and if you're not sure, don't flash!!
