Any firmware can be used anywhere. Most will have all the languages. These are roms from the release of the a100/101 (ie, the original 3.2) so if you want the latest, I would use zeronulls ics stock rom http://xdaforums.com/showthread.php?t=1611696

I'm pretty sure it had 20-30 languages. Also if flashing from 4.0 to 3.2 you will need to factory reset after it hangs on the android logo.

My problem in short: I cannot upgrade anymore after an A100 downgrade back to an A101 ROM!

I wanted to try out other A101 modded firmware, rooted it before (I used another method where I just had to run an run-windows.bat or similar, see http://jebcomnetworks.blogspot.de/2013/05/acer-iconia-tab-a101-jetzt-sicher-und.html it works really. SuperUser etc. worked.) and then tried these instructions:

http://xdaforums.com/showthread.php?t=1487142

I can always flash an A100 ROM, but after that I can never flash back to an A101 ROM (so I am stucked at point 9 of this instructions)

I tried several A101 Stock ROMs, it seems to flash successfully but after then it hangs after reboot at the Android Letters Scroll Screen (or should I wait 2 hours here? ;))

First of all it is very hard to find A101 Stock ROMs at all (as the links of this threads are all gone (404) now). In the instruction you say you can install any (Stock?) ROM, for A100 as also for A101. Is this really true or has it e.g. to match for the suffix like A100_..._COM_GEN1 and A101_.._COM_GEN1? Others also asked what this COM_GEN1 etc. means or EMEA. That would also be fine to know. I can just guess its GEN for generic and EMEA for Europe + Middle-East + Asia but I could be wrong.

Some kind of (e.g. clockwork) "recovery" is not installed yet.

What I have tried:

I Always used this A100 ROM to downgrade:

Acer_AV041_A100_1.014.00_WW_GEN1

Then I tried these A101 ROMs to upgrade back:

SD_Acer_A101_2.005.06_COM_GEN1_full_user

Acer_AV041_A101_1.014.00_WW_GEN1-update-HC-ICS (several update.zip - seems not to be STOCK)

Acer_A101_1.008.06_COM_GEN1

Acer_AV041_A101_1.014.00_WW_GEN1-root (modded?)

But all hang at reboot with the Android Letters Color Scroll Screen. Any advice - even a small one - would be nice, so I could re-utilize 3G
[Acer Iconia Tab A100] Romman0:
Have you tried to factory reset with the hardware buttons after flashing an A101 rom? Sometimes it is needed if swapping between HC and ICS roms.
[Acer Iconia Tab A100] Airport1:
I would give it a try, but before .. can you recommend which A101 ROM is "the best" (I mean, causes the lowest trouble, even if I have to update it OTA after that?). And another thing, just to understand what "we" are doing here, what is done by this

/system/bin/cmdclient ec_micswitch '`echo 'ro.kernel.qemu=1' > /data/local.prop`'

? I never found anywhere something about it.

BTW, I can navigate in the recovery menu between the choices by volume down/up, but no hardware key (even home or power button) will select my choice. How do you select a choice here?

(maybe it does not work at all, as seen in this video: http://www.youtube.com/watch?v=CWFlA1W08wE )

But for the first, a recommendation which A101 ROM to take would be completely perfect.
[Acer Iconia Tab A100] Romman0:
You can't select anything in the stock recovery, that is just the way it is.

Try this full a101 stock rom, posted above. http://www.imeiserver.org/download/...=SD_Acer_A101_1.013.09_COM_GEN1_full_user.zip
[Acer Iconia Tab A100] Airport1:
OK, meanwhile its solved. See below. Thanks a lot!

> Have you tried to factory reset with the hardware buttons after flashing an A101 rom? Sometimes it is needed if swapping between HC and ICS roms.

I did now the update.zip procedure with your suggested SD_Acer_A101_1.013.09_COM_GEN1_full_user.zip

After that it was the same: only the Android letters scroll screen.

Because the stock recovery menu does not work to select something and even more I did not get how to reset the device by hardkeys I used the RESET hole and sticked something in for some seconds, then it rebooted but its still the same:

I get only the Android letters scroll screen.

Could this depend on the combination of A100 and A101 ROM needed?

Could this depend whether you do OR DO NOT the commands between like in this "how to root instruction"?

I am out of ideas. All I can currently do is going back to an A100 ROM, so I lose 3G

OK FOLKS. ALL SOLVED. AFTER I FOLLOWED THESE INSTRUCTIONS _AFTER_ FLASHING A101 ROM:

http://panam.acer.com/acerpanam/tablets/2011/Acer/ICONIATab/ICONIATabA100/ICONIATabA100faq9.shtml

The only curious thing is that I am now fixed to Android 3.2.1, when I click System-Update it says device would be on latest version, but maybe this takes some time.
[Acer Iconia Tab A100] Romman0:
Yes that's what I meant by a factory reset with the hardware buttons. I should have been a little more specific.

The update may take a while to come, or if you can find the official ICS for the a101.

I believe the stock ics rom version is AV041_A101_1.014.00_WW_GEN1, but their maybe more than one.
[Acer Iconia Tab A100] Airport1:
How can I upgrade an Acer A101 to 4.x again?

Sorry to bother again, but I am still fixed to Android 3.2.1, that means I did not get any new version (although it should be available, as 4.x has been spreaded some months ago). So I searched again today for either a modded ROM _with_ 3G (but that seems not to exist) _OR_ a stock rom. But I had no luck for both. Also on the official Acer site there is no download for it. Can you lead me to a page where I can get a stock rom 4.x for Acer A101 _with_ 3G? It is a German model, if that matters (e.g. because of frequencies, bands etc.).

Is this a "trouble-less" good choice? http://xdaforums.com/showthread.php?t=1629453 But I read about "removing official bootloader" so it might not be..
[Acer Iconia Tab A100] Airport1:
Could help myself. In this thread you can find - a little bit hidden - the Stock Rom for Android ICS 4.0.3, under this link:

http://narod.yandex.ru/disk/4772874...4bd/Acer_AV041_A101_0.004.00_WW_GEN1.rar.html

It is named

Acer_AV041_A101_0.004.00_WW_GEN1.rar

You put in sequence each of the 4 update1 2 3 4 zip file renamed as update.zip on the SD card of the device, turn off and hold Volume up when turning on. You start this with update1.zip until update4.zip. After that you have 4.0.3 ICS running.

On the side of the box you saved I hope ?? also on the Acer site if you registered the unit.
[Acer Iconia Tab A100] andreagragnato:
No, none of them. I've solved anyway. ( I was almost crying :( )

I was lucky doing this way:

erased sd, put update.zip in it, powered up the tab with power button+volume left (or right, or both, i don't remember, try any combination if you need to). Than at top left instead of "spin forerver" there was mounting kernel and something about update.zip. Android logo appeared with gears within it and a progress bar. 10 minutes after I've got back my tab to life without any change, as I left it before this problem. Seem that was solved only the problem with the recovery console and any data/setting was still there.

Thanks for the quick reply. I will register it as soon as possible.

I've tried to obtain the cpu id with USBDeview. The number I've obtained I think was the correct cpu id but EUUs output me that was wrong.......

i just got this tablet from a friend a few days ago and it has been stuck on the android logo since then. I have tried to manually flash the files from a microsd card. By pressing power and volume up key, it loads up the update.zip file and android gears are moving as usual, but at about 80% the gears stop but the installation finishes up. The tablet then restarts and would go back to the same android loading screen. am i doing something wrong? any help is appreciated. thanks

Maybe u had a bad download of the stock ROM? Try redownloading the file and re-updating ur A100 with it. If it still doesn't work, try another one of the stock ROMs and re-try the update.
[Acer Iconia Tab A100] vatovec:
I'm still a bit of a newbie with this tab, and I have a question about the flashing:

1. How do I go in to recovery on a100? I got in to recovery with "adb reboot recovery" but there was just an android logo and nothing else, how can flash these roms through recovery?

2. APX mode? How can I use it? How can I flash ROM with this?

Thnx!
[Acer Iconia Tab A100] aznmode:
Download the file and put in root of an SD card. Put the tablet in recovery by turning it off first. Then holding volume down (the button closer to the power button side) then press power to turn it on. When it boots keep holding the volume till you see it go into recovery (release volume button) and it will look for the update.zip file in the sd card and update your device. You will see the green android with green gears moving along with a progress bar at the bottom. When it's finished your phone will boot back.

Now does anyone know where to get 3.2.1? It looks like the a100 version in the link is still 3.2
[Acer Iconia Tab A100] cris:
Hoping somewhere he can help. My A100 is getting stuck at the ANDROID screen after the acer logo. I have tried the update.zip method with a freshly formatted SD card. I have also tried the APX method, whenever I try this the CPU ID I got from usbdeview in w.e format with or without the 0x0 or just 0 it always says invalid and then just stops. Has anyone actually confirmed that APX restore will work on the A100?

Edit:

Almost forgot, while stuck on the android screen I am able to connect it to adb and so some basic stuff. shell, copy files to certain folders, etc...
[Acer Iconia Tab A100] cris:
Sweet, thanks, downloading as I type this. Hope I can get this tab up and running again or I'm gonna have to return it...
[Acer Iconia Tab A100] aznmode:
the Multiupload files both are corrupted after I download. Cant open or the tab give an error when trying to install to phone. Is this legit?

EDIT:

Ok so doing more googling I found the update.zip is encrypted by Acer. You will need to use this decrypting tool.

http://xdaforums.com/showthread.php?t=1099673

Rename the original downloaded file from the multiupload link to just "update" or whatever you want to call it. The decrypter couldnt find the file till I shortened the name. Open the decrypter and select "input". Look for the renamed zip file and press "Start". The output will be transferred to the same directory as the original but up to you if you want to change output directory. Somehow the decrypter slowed down my windows XP so I had to close everything but the decrypter. The new file will be called in my case "updatedecrypted.zip". Unzip the file and inside you will find a txt file, AMSS.zip, and an update.zip. This update.zip is what you want to copy to the root of your sd card.

So again to flash:

1. Turn off tablet

2. Hold the top volume button close to power button first then press the POWER button.

3. Wait for the text in the corner of the screen to show up so you know it's going to recovery.

4. Release both buttons.

5. You will see the green android with moving gears and progress bar on the bottom.

6. Sit and wait......

7. The progress bar will all of a sudden stop at about 85% of the way. DONT PANIC and DONT start holding the power button to reset it.

8. The progress bar will stay in that spot for about a minute then the tablet will reboot.

9. The tablet will be stuck at the "android" screen for a while (I think about 3 minutes) again dont panic and just wait. Eventually it will boot completely.

10. Now jump and down, scream and shout with joy that you are now on 3.2.1. Ofcourse you can always go to setting to confirm before you rejoice.

11. I would probably recommend doing factory reset.

12. Last but not least thank the appropriate people that provided the links and the decrypter.

Link to decrypted update.zip file.

Update: I was still able to root using terminal emulator.

It fixed the headphone issue. That is the big one for me. Follow goofball2k's instructions and you are good to go. I found no need to factory reset after so no data loss.

I have a problem to perform the update.

First of all my configuration: Acer A100 (obviously), a 8 GB micro SD (fat32 formatted), the update.zip. I write from Italy so my Acer A100 has the Italian Rom.

I tried putting the update in the micro sd but every time I try to "hold the volume button close to the top power button first then press the POWER button." Android I see the green Android and then it stops, I see only a green Android with an exclamation point.

I downloaded the update (decrypted) three times on two different computers and I also realized with the decrypted version + the tool.

What's wrong?

Ps: my Acer A100 has no root
[Acer Iconia Tab A100] aznmode:

And, most important...you need to wipe data after? or you conserve all your apps?

Overall, the update addresses a headphone issues in which sound would still "bleed" thru the a100's speakers even when you had headphones plugged into it. Also, it seems to have a tad bit better battery management as well. Other than that, it still feels the same.

As for your second question, no. Wiping your device IS recommended but is not required. I updated to 3.2.1 and all my data was still intact and well. I did not encounter any force closes or corrupted data whatsoever. But as always, exercise caution whenever updating, everyones "update results" vary.

Yeah, I just went ahead and updated. The reason I asked is because Acer wants me to send my tablet in for a warranty repair but I was rooted. So I wanted to restore it with the same version that came on it. Either way I don't think they'll find out I manually flashed the 3.2.1 update.
[Acer Iconia Tab A100] aznmode:
Joe are you sending yours in for the touchscreen issue? Also you can get the 3.2 update.zip and do the same process. I've gone back and forth between 3.2.1 and 3.2 to test some things between the 2 versions.
[Acer Iconia Tab A100] Joecascio2000:
Yeah I'm sending it in to get the touchscreen fixed. It appears to be a grounding issue, not fixable via software update. Also, It seems to affect my tab more than others.

I wanted to put the same version as when I got the tab (Acer_A100_1.0.18.05_COM_GEN2) just in case they have some way of checking, but I don't think they can. Plus the hardware techs probably don't know anything about the software.

Either way I updated to 3.2.1 and re-rooted LOL. So before I send it in I need to re-flash stock again. Hopefully some more builds get added to the OP.
