Hey guys ... just bought used Acer iconia A500 with rooted 3.1 honeycomb , and it's not getting any official update 3.2 ,,,, is it possible to go back to it's original (official 3.0) ... idon't want any rooting on my tab and i don't know alot about these things .... so can someone please tell me the steps what to do ????
my kernel 2.6.36.3-00005-g5dff38c
build # Acer_A500_3.019.04_com_EGN1
basedband version unknown
i really appreciate your help guys .
Run Acer recovery service - APK is here somewhere and on market. Tick Acer recovery. Run Iconia root (have to get from here somewhere) and select unroot.
Install the unstable 3.0.1 on your tablet, then go to settings>about>update tablet. This should unroot tablet and then install HC3.2 on your tablet if theres an update available....
This question should also be in the QA section of the forum and NOT developement. You may get flamed....
Don't need to unroot, just run acer recovery, put the update.zip on memory card for hc3.0.1 and boot to recovery, hold tab landscape, push volume down - volume button pressed towards the power button and press power button. Hold in until words appear on top right corner when "Acer" appears on screen. This should then load the hc3.0.1 update file... DON'T INTERRUPT OR POWER DOWN UNTIL THIS FINISHES...

I would just think running an official 3.2 rom would suit the purpose, rather than that highly un-stable version. But, if the user want 3.0, who am I to argue
just flash a full stock rom that you find in vache thread http://forum.xda-developers.com/showthread.php?t=1113878
It will turn your tablet to full stock and then if you go to update on tablet it will auto update.
You will lose root and clockwork mod recovery.
Why don't you flash one of the already rooted vanilla 3.2.1 ROMs that are floating around the forum? It is easier than restoring the original, they are already upgraded to the latest OTA and you don't lose CWM and the rooting.
Just wondering.

Stuck on "ACER" logo at boot...won't boot & pc can't see it.
If I go into recovery I get: Android Guy & Box with arrow then a triangle with explanation point.
I was running ICS Rooted OTA.
I was trying to return the tablet to stock ICS & Boot Loader, when I messed things up.
(Sold Tablet--Need to restore it to factory look & feel.)
If someone could please advise I'd GREATLY appreciate it.

Have you tried to restore HC boot loader on an ICS rom. Don't worry just download one of the update package from the following link. As you mentioned you were on ICS rom then try ICS update only as it will update boot loader back to ics. Decrypt the file using Acer decrypter on the same link. Place the update.zip on your externel SD and then boot in recovery. Let other recovery install the update file.

Only Acer logo
Hi all,
i have the problem that the A500 does nothing else but show the Acer logo.
The only thing i can do is use TWRP.
What did i try:
I tried flashing some roms using TWRP, also some older ones but no luck.
I tried using an empty SD-card and then start with Volume - and Power but no luck
What can i do...i am stuck...
Anyone? Still have a non-working Iconia 500...boohoo
Is it an option to flash it with Clockworkmod / CWM, reboot, flash it with an Acer ROM ?

Well, telling us you've "tried some other ROMs" and have had "no luck" is pretty much telling us nothing at all.
What ROMs -exactly-?
What -exactly- do you do in TWRP?
What version of TWRP?
-Exactly- what error messages do you get?
What bootloader do you have? Sounds to me like you might have the HC bootloader when trying to install a stock ICS ROM. This is not going to work, period.
If you want help, you've got to provide enough info to help you.
Hi FloatingFatMan,
thanx for your answer.
I tried TWRP v2.1.0 with following roms:
Acer_A500_4.010.42_7.006.01_COM_GEN1
Acer_A500_7.014.14_041.203.01_COM_GEN1
cm-9-20120708-UNOFFICIAL-a500
recovery-ra-iconia-3.17-
gnm
Today i updated TWRP to v2.2.0 using openrecovery-twrp-2.2.0-picasso-signed and tried the cm-10-20120730-UNOFFICIAL-a500.zip rom. Same problem, after system reboot i only see the acer icon (permanent).
Also tried cm-9-20120708-UNOFFICIAL-a500.zip but same problem.
What can i do?
There are three main ingredients when customizing a device:
1) BOOTLOADER
2) RECOVERY
3) ROM/KERNEL
You provided answers to #2 and #3....what about #1??? What BOOTLOADER are you on?
Thanks for your reply.
I never changed my bootloader so that will be stock i think.
Finally i managed to get it going again. The trikck was to use a 3.0 stock rom. That worked.
From there i now use ICS (stock) which is fine at first. I had not seen anything but the Acer logo the past 2 weeks, so the Acer ICS will do perfectly now.
But for later on: can i use CM9 or CM10 with default bootloader + TWRP 2.2.0?

You'll need the unlocked ICS bootloader. Civato made a great guide over in the DEV section.

OK to explain for you.
ICS and JB require the ICS bootloader to run. They will not run on the HC bootloader unless specifically modified to do so. Also, no HC ROM will run on the ICS bootloader. This is why none of those ROMs were working for you.
Flashing stock ICS has updated your bootloader with the locked ICS one, so you probably won't be able to downgrade to any HC ROMs, or use any custom ROMs anymore. You can, however, use APX mode to install the unlocked ICS bootloader which will enable custom ROMs again.
I don't recommend trying to install ANY custom ROMs now until you'd flashed the unlocked bootloader. Instructions for this are in the Development section. Read VERY carefully before proceeding and if in doubt, don't proceed.
Hi FloatingFatMan,
thanks for the explanation.
I think i will stick to the stock rom at first. The APX way is not without risk...but maybe in the near future...

I am having the same "stuck on acer logo" issue. I am totally novice when talking about how to flash to ROM and stuff. Can you please direct to me a simple "dummy guide" on how to flash back to factory rom and fix my tablet. I tried the hard reset by holding down volume up and pwr button and on/off button, where i see the 'erasing..." but it still goes back to logo screen.
Please help me with my situation. Thanks in advance.
Have a look at this video
That is an example on how to do it.
I can list any number of things that I've done/tried, but there have been so many! I'm not a noob when it comes to flashing ROMs, but I'm a new to the Acer Iconia Tab A500 and that's the problem, I think.
Anyway, I got the A500 with Honeycomb and I let it do the ICS OTA. No problem. Then I rooted it. No problem. I got to here: http://forum.xda-developers.com/showthread.php?p=31546261#post31546261
Then I decided to change the bootloader and that's when I borked something up. It would still boot into ICS just fine, but I couldn't get into recovery. I decided to try downgrading to Honeycomb 3.0.1 using the "unstable" update.zip, but that just ruined everything as now I'm completely stuck. I can't boot at all, it just hangs at the black screen with white Acer letters and red "boot verification failed" in the top left corner. Recovery gets me the dead Android image with the black exclamation point in a red triangle.
I have looked all over and I've read dozens of XDA threads...and I'm sure I'm missing the one thing I need to do to fix this, but heck if I know what it is. I have the Acer drivers installed on my computer, I have a variety of tools (nvflash, blackthund3r's apxflash, etc) waiting to be used if necessary.
So, please, I implore you...treat me like I'm dumb and walk me step-by-step through whatever it is I need to do to get my A500 back up and running! Thanks for your help!
UPDATE: Many hours later, I fixed it! I did another update using the full, stock image of Acer_A500_7.006.01_COM_GEN2 (just guessing about whether it would work or not) and it seems to have done it. Sure, I'm back on Honeycomb 3.2, but it worked. And then I was able to use AfterOTA to root and get the CWM bootloader on there.
So my next question: what do I need to do in order to get ICS? Can I just flash an ICS ROM from CWM, or do I need to update the bootloader in some way?
Thanks!

Yes and No.
Now that you are on HC 3.2, you're going to need to do the process again.
IE: Unlocked Bootloader and CWM
The problem you had at first, is that when you flashed the UNL bootloader and CWM, you missed 1 tiny step. (lot of people forget to do this) And that is to delete the boot-recovery.p file from the /System. If you do not, you can install CWM, however, when you boot into stock ICS, your CWM gets overwritten. Another little trick from Acer
In the Dev Section, in the stickies part, Civato posted a link to a full ICS Stock Root Rom, With all the nasty stuff removed. (bootloader, recovery files). Download it, put it on your Ext Sd card.
http://forum.xda-developers.com/showpost.php?p=31572588&postcount=6
Then do the unlocked bootloader + Cwm again. Only THIS TIME, when it finishes, boot the tab immediately to CWM (vol- and PWR). And install the modified stock rom, or one of the custom roms.
Don;t forget to get your HC UID number written down before starting the process. Also it's good after ICS to get your ICS UID number also written down.

Hi everyone.
Just repeating again - the model I have is A501 on stock 3.2.1 Honeycomb - a more USEFUL tablet with 3G and WIFI capabilities...One would think it would be a much more popular model, but the A501 doesn't have its own board on XDA; its merged with this board for the less practical A500. Basically, I have created this thread as I don't want to take any 'extra' risks in successfully installing ROOT with the CORRECT ROM with the most updated version of Android available for this tab, for example Jellybean...

Can someone link me the a fully detailed video or post on here on installing the ROM i mentioned above (if that's the best one to go with, given what I'm on now; A500 3.2 and still keeping root), or to install some other A501 ROM which is for at least Jellybean or ICS?

Your best bet is to install a good 501 HC 3.2 and get on HC for your 501.
The files are available. What you'll probably want is a full HC Update rom for the 501. Note that some of these Acer roms are encrypted, so you'll need to decrypt it first. You can find the decrypting tool in the Themes and Apps forum, as a "Sticky". After decrypting, you can pull the update.zip out of it, and copy to Ext SD (do not extract, just pull the update file out). Boot the tab holding Vol- and PWR I believe. Might be Vol+ but I can't remember. This should force the tab to look for update.zip on your SD and install it.
I would use this one;
Acer_A501_1.309.02_4.031.24_COM_GEN1
After it installs, and you get it set up, you need to get Acer Update Enhancer from the Play Store. This will allow your tab to get the ICS OTA.
Keep in mind, there is only 1 official ICS OTA update for the 501, so don't expect more. It may do it in 2 steps though.
If you want root on ICS, there is really only 1 way to get true root and adb system remounts. And that's to flash the V8 unlocked ICS Bootloader, and flash an insecure boot.image. There's currently a small package that'll give you somewhat root, but it's a pain and really doesn't do a good job. So it's better to get the V8 and unsecure boot image. Might be a good idea to also install CWM Recovery at the same time.
Get the correct rom installed first, then check back if you need help.
Oh yeah, one more thing. When you are on HC 3.2, get your UID number and write it down somewhere. You need this as a safety precaution. There's a good sticky thread on how to do it. Pretty simple really.
MD
Ugh. I have a pain in the A$$ version of AVG...even under advanced settings there was no disable options. Managed to figure it out to run the Acer Decrypter EXE and fix the image you have advised I should download and flash. Will give that a go now...
Thanks again!
Just to fill you in, this issue is solved.
1. Used TimmyDeans rollback V4 tool to a 500 rom
2. SD card was not recognized in CWM or Stock recovery. Was however recognized in the HC OS.
3. Formatted SD Card using Mini Tool formatting app. Format primary partition only to fat32 (defaults)
4. Decrypted and pulled update.zip from this 501 HC full update rom

Hi MD,
I have Acer Iconia A501 tablet. My tablet suddenly showed andriod logo with exclamation mark when it was being used. Upon looking at your posts, I found the resolution which I tried. I am not expert in this all, but I tried running your ROM "41-124-01-A500-update" from one of your posts which was actually meant for A500. This resolved the issue successfully and tablet was up and running.
Then further I found full ROM for A501 as mentioned below and thought that I should try the ROM meant for the model of my tablet.
I successfully decrypted the ROM that you mentioned "Acer_A501_1.309.02_4.031.24_COM_GEN1"
When I tried to update it with the mentioned ROM update.zip, it did updated it from SD card and passed android symbol with those gears running. However, when it restarted the tablet by itself, it showed ACER logo and then it showed "ANDROID" (spelling in blue color) which kept on flikering slowly for long long time....for more than 30 minutes and did not moved further. Can you please let me know whats could be wrong?
I also tried ICS ROM, but that didn't worked (it failed). So after couple of trail and error, I moved back to A500 ROM update.zip which I knew that is installing successfully.
Can you please let me know what shall be done in case I want update.zip for A501? It will be highly appreciated if you can upload update.zip directly that I can use and that gets installed successfully.

Hey Muk, I can probably guess the ROM you installed doesn't do data wipes and such, so it caused an animation loop.
Try this one. It's an SD ROM, so it "should" wipe your Data, along with installing the ROM.

As you probably discovered, Acer has pretty much removed almost all tablet ROMs. I snagged a few the other day, then checked yesterday, and they removed all from their support site.
I would guess they are getting out of the tablet business.
Also, they shut down their OTA Update servers for a few months now.

Can you please let me know whats could be wrong?
I also tried ICS ROM, but that didn't worked (it failed). So after couple of trail and error, I moved back to A500 ROM update.zip which I knew that is installing successfully.
Can you please let me know what shall be done in case I want update.zip for A501? It will be highly appreciated if you can upload update.zip directly that I can use and that gets installed successfully.

Muk

A big thank you to Moscow. I have tried the above link but still no go.. I have seen on Acer website they have updated the OS but all Android 4.0 ICS and nothing with Honeycomb. The tablet was initially with Honeycomb. Please advice. Thank you and Best Regards.

Hi MD,
Thanks for your super fast response. I am downloading the ROM for A501 from the link provided by me. I will update you if it works in my tab.
I forgot to mention you about one message that I received once tablet is restarted. So, once ROM for A501 from SD card has performed its job successfully....that is that android symbol with gears in its tummy is successfully finished and tablet restarts. It shows "Acer" (spelling logo) and then after it gets stuck at "android" (spelling logo). Between these two, it displays two lines messages on top left corner for 2-3 seconds that the "blob is illegal - abort" and then gets stuck at "android" (spelling logo). I think this might be useful for you to identify something.
Another thing about wiping out the data, in starting when we press volume down and power button, it does display message about SD card (still not not sure about whether it might be wiping out the data or not....I believe you might be correct that it might not be wiping out the data).
Another thing, that I found in my backup is that when I purchased this tab (A501), I downloaded HoneyComb 3.2 Kernel Source Code from the Acer support site. Is this something that you can do magic with and provide me with update.zip? Please let me know....if you can do magic with this, then let me know how shall I share it with you.

Trouble installing ROM for A501
Hi MD,
Thanks for your super fast response.
I tried downloading the ROM for A501 from the link provided by you. It downloaded it from the cloud, but at the very end it displayed message "Decryption Error". Still I tried extracting "update.zip" from the zip file, but it displayed message that the archive is corrupt and file is corrupt. Can you please check at your end and provide me with fresh link or directly with update.zip? For your reference I have attached screenshots of errors.

Trouble installing ROM for A501
Hi MD,
Please read my earlier message and then read this one.
Thanks a lot....your answer about my first problem resolved everything.... (your answer was "that the ROM that I am trying to install is not clearing the data"...I verified that the ROM is clearing the cache, but not the user data. I can confidently say that you correctly identified the issue as when the ROM installation was stuck at "android"....I switched off my tablet and tried installing again the old ROM for A500 which I knew that it is working and instead of asking me to configure the tablet (i.e. time zone, date & time setup, etc.) after installation, it simply logged in and started my tablet as usual....that means that when I was trying to install ROM for A501, it was not clearing user data and was then hanging).
Now coming back to the link that you sent me in previous message, I was able to download the zip file successfully in the second attempt. I extracted the update.zip and it did not work. It showed the similar problem of getting stuck at "android". However, with your great answer that you gave me, I cleared the user data and cache manually by pressing vol up + power buttons simultaneously and then when "acer" symbol displays, releasing only power button and turning on and off the lock button. This cleared user data and cache. After that, since update.zip (that you provided) was already in my SD card, it installed the ROM and tablet works perfectly. Thanks a lot....:good:
One question, when it asked me about the zone, it had only few countries like US, UK, etc. I couldn't find Australia...is it because this ROM not for Australia? I understand that this is not an issue, but if you find anything for Australia, do send me.
Another thing, is this HoneyComb 3.2? Will 3G and GPS work in this one?
Do let me know if you can do some magic with HoneyComb 3.2 kernel source code that I have as mentioned earlier.

Muk

I'm mobile right now, so can't go into big detail.
In your settings, about tablet, you can always find info on which specific OS you have. If you indeed have an A501 and the settings tells you that your tablet is a 501, then your 3g and GPS should function.
The only 2 differences between an A500 and an A501 is of course 3g. Also, they use different GPS radios. So you can install 500 Roms on a 501 and vice versa. Just the above 2 items won't work. Also, I believe I gave you a 3.2.x ROM. Getting it to ICS 4.0.4 may be a problem.
I revived my own 501 last night by putting the motherboard in the oven, but now it doesn't read my ext SD card, so I may be stuck on 3.2. Eh, no problem.

Hi MD,
Apologies for very long replies. Wanted to convey the message in detail how I did it so that it might help someone else like me.
Thanks for your response. I have tested it, 3G and GPS is working fine. I believe, before my tab encountered this problem, it was having version 4 which should be ICS. At that stage I didn't had any problem with my tab...I believe it was there for long time.
If you have good known ROM for ICS, please forward me I can try on my tab. If it doesn't work, then will re-install the Honeycomb that you sent earlier.
One more question....when I try to update the system from "About Tablet" in Settings, why it displays message the the "network is poor" and advices to move to better coverage? Though, I am just besides my WiFi modem and coverage is almost 100%.
And @jonnybrave: If you are referring to the ROM that I successfully installed which was sent by MD earlier, then it does not need any decryption. So you can use the link sent by MD earlier in this post. And if you are referring to the KernelSourceCode that I mentioned earleir, then it needs some kind of processing in Linux machine and then you can create some image.....this is was I know about it....sorry not an andrion guru. Please let me know what you are referring to.

Mukesh

You get the message as do all 500/501 owners (it can change depending on version of Rom).
Acer no longer gives updates to any of their devices (regardless of age). These are otherwise known as OTA Updates. So they have closed their update servers, so now we get some "message" that absolutely means nothing.
I suppose Acer is getting out of the Android business and no longer supports anything. Nice job Acer.
As for updating to ICS (or any other version), I have a few update files. Generally though, the update files must be matched to the current version of your tablet. Sometimes you can run a "full update" and it will work.
The problem, is these tablets are getting old, and the nand memory can go bad. Running an update can cause a variety of problems such as "Stuck in APX" mode, stuck at bootloader, stuck at boot animation. Then we have to go back to the EUUS file, or an old SD ROM file. So you run the risk of doing things all over again, and the risk that it just won't work again. (I spent a couple hours last night, and was almost ready to throw it in the garbage)
For example, I'm pretty much stuck at 3.0.x or 3.2.x. I've already disassembled the tablet and put the mainboard in the oven, just to get it back to life! And after numerous attempts to get ICS on it, I've pretty much given up before it hard bricks again. In fact, I can't get a 3.2.x EUUS to work on it, so it is stuck at the 3.0.x ATT EUUS. Eh, it's my little girls tab, so as long as it gets You Tube and browser, it's pretty much ok.
Trouble installing A501 ROM
Hi MD,
I am in the same boat as you...lol...This tablet is mostly used by my daughter and as long as it is solving my daughter's purpose, we are happy
I was just curious about that message as to why that is happenning, but after your clarification, it is clear to me as to why it is happenning.
My tablet is working as normal and everything is working fine...so we are happy with what we have.
Thanks a lot!

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!!
