How to unbrick Iconia tab A500

On power up I get just the Acer logo. There is a post from 2013 that describes how to unbrick but the instructions don't work. It suggests going to the site that lets you download Acer drivers and manuals, viz http://us.acer.com/ac/en/US/content/drivers#_ga=1.181574820.267539145.1417479834. This should give a zip file that contains 'update.zip' but it doesn't; it contains a file with a name that ends 'Driver Setup.exe' and I don't think that is what I want. The site address has 'US' in it so I looked for the corresponding UK source for drivers and manuals which is http://www.acer.co.uk/ac/en/GB/content/drivers and I then typed in my SNID and selected the OS Android 3.2 Honeycomb (ice cream is 'not available' and I can always upgrade later). The zip file that results contains the two files H_A31H_A32H_A500_A501/1.inf and
USB_Acer_1.00.0524_A30H_A31H_A32H_A500_A501/ICONIA TAB USB Driver Setup.exeand again this doesn't look right (the 1.inf file is all about Windows). I have not tried running this because it is not 'update.zip' and I'm afraid it will install Windows instead. . I need the file update.zip. Can someone please tell me where to find it? Or any other way of unbricking an Iconia A500.

Hello Ironfly. Thank you for your comment. I have tried a factory reset, if you mean that game with the volume button. If I hold down Volume- and press power on I get the Acer logo for ever and if I hold down Volume+ I get the dead Android. You say that to get the file update.zip I should click on the OS tab but where is this? Do you mean in the Drivers and Manuals page? I did that and selected Honeycomb 3.2 which was the OS installed on the tablet when new. I should be delighted to hear any other ideas about how to get a file update.zip and not some Windows substitute.

I have Iconia Tab A500, running 3.0, need help updating using microsd card, got Acer update download

I have Iconia Tab A500 running 3.0, need help updating, I downloaded all updaes list in the acer supprt, all versions, 3.0, 3.1, 3.2, and 4.something, I read on the acer support somewhere I can use a microsd card to update my device, because acer no longer provides automatically, when i try it says "poor network connection, move to anthoer location.", Do I need to update all the listed updates, or can i only update, using the 4. 0? to get the last known update. I also downloaded, "Documents, Apllications, Drivers, Patches, and O.S..... How do i intsall all these updates, I think am running the very lowest version available, Please Help me... Thank you in advance.

the update listed on the acer website, that mentions the a500 update is 'kernal source code (for Android 4.0 Ice Cream Sandwich) it's 96.7MB's released 2012/05/08' is that the right one i need?

Cannot transfer from ADE to Acer Iconia Tab a500

I have used my Adobe ID and password and installed ADE on my pc (XP), but ADE does not recognize my Acer Iconia Tab a500, which is listed as a supported device. I have registered the Iconia tab and also authorized it with the same Adobe ID and password. The installation instructions tell me that my e-reader device will appear as a new bookshelf in the library when the device is connected to my pc, but it does not, so I am unable to transfer from my pc to the e-reader. Any ideas?

I just got an Acer Iconia A500 for Christmas and was going through the same problems as "cantreadit". Since I'm not the most technically advanced person in the world (I'm an old fart in his 60's), I was panicking about not being able to use this part of my tablets capabilities, and started looking for a cure on the internet (Acer was almost no help). I couldn't get past the sign-on to Adobe ADE, and always got an error message. I saw a comment about a "time-expired" error being caused by the tablet and the computer mot having the same time shown, but my tablet was the exact time as my computer. When I went a little deeper, I found that my tablet didn't have the "TIME ZONE" marked correctly (mine was set off of GMT, the default). When I tethered my tablet and computer together and had both open to the time I reset my tablets time (the tablet doesn't set to the second, so I waited until the computers second hand got to the exact minute and clicked on the tablets clock - I don't know if you need to get that exact, but....). When I went to my tablet and signed in, this time my authorization was accepted.
Note: Adobe ADE still doesn't show my tablet as connected, and I can't download from Adobe directly, but (being an "old fart") I always save my books first to a folder on my computer before opening them to ADE. When I went to my tethered tablet and copied the folder with (the DRM protected) e-books on my SD card, then went to LumiRead, then settings, then to "manage my book folders" and added that folder to the folders that LumiRead looks at, ALL the books were there and readable. Saving the books to a folder first (which my Techno-Geek" son and son-in-law said was un-necessary) seems to have worked out good for me.
My last concern is that I don't know if Overdrive will also "see" the ADE authorization and let me download books from my local library on line (which I use a lot for my dedicated e-reader), but I'm going to check that out later today (here's hoping that works too).
This may not be the same problem that the rest of you have been facing (my problem may have been too simple for the rest of you guys to miss), and it may not be the complete cure (I still have the Library & Overdrive to checkout). Also, the rest of you may have trusted the system to work properly, and not "stupidly" saved the books you bought to a folder on your computer (like a skeptical "old fart" like me would do), but for the other "Old Farts" out there, this may be the cure your looking for (no matter how simple it may be).

Acer Iconia Tab A500 and UMW190 USB Modem?

Can the UMW190 USB modem be used with the Acer Iconia Tab A500, or is this tablet supposed to be compatible with Verizon 3G/4G?

I'm sorry but the Acer Iconia Tab A500 is not supported by Verizon Wireless. This tablet is not one of our devices.
Thanks very much for your posting!

[Follow-up] JavaFX ARM Preview on an Iconia Tab A700

Hi all,
I'm going on with my work after a previous discussion:
Re: JavaFX on ARM tablet
Now I have an Iconia Tab A700 with Android 4.0.4, I locally mounted on it an image of Ubuntu ARM that I access via VNC.
First of all, is the Iconia Tab A700 a correct ARM device that I can use for tests?
I've then downloaded the JavaFX preview (http://jdk7.java.net/fxarmpreview/index.html), unpacked it on the Ubuntu ARM and tried to run a JavaFX application.
I receive this kind of exception:

How can I solve this?
Thanks.

First of all, is the Iconia Tab A700 a correct ARM device that I can use for tests?I don't think so.
I think you should use the hardware (and follow the instructions) documented in the JavaFX ARM developer preview installation instructions:
http://jdk7.java.net/fxarmpreview/javafx-arm-developer-preview.html
For example use a BeagleBoardXM:
http://beagleboard.org/hardware-xM
Connected to a compatible display:
http://www.chalk-elec.com/?page_id=1280#!/~/product/category=3094846&id=13727568
Really, JavaFX on ARM is a prototyping platform targeted at an extremely limited set of hardware at the moment, not a production platform.
It is in public preview now so that you can test it out and provide feedback via bugs and feature requests at http://javafx-jira.kenai.com.

[SOLVED] Help needed with ACPI accelerometer - Acer Iconia Tab W501

Hi,
I am trying to get the accelerometer working on my Acer Iconia Tab W501
In windows, it reported as a BMA150 device, so I have that driver loading on boot.
After months of googling and making a mess in /sys, I still have not got the device working. I was working under the assumption that the device hangs off the i2c bus, but a "lucky google" today uncovered that it is showing up through acpi - acpid is present in my daemons array of rc.conf and the kernel module acer_wmi is also loaded.
The device is certainly sending signals to the kernel. Upon boot, dmesg ends up as follows:
[ 11.689709] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
[ 12.108374] EXT4-fs (sda2): re-mounted. Opts: commit=0

[ 22.459133] wlan0: no IPv6 routers present
Now, if I rotate the device, and run dmesg again, I have the following:
[ 1255.189705] acer_wmi: Unknown function number - 5 - 1
[ 1257.363688] acer_wmi: Unknown function number - 5 - 1

[ 1308.653700] acer_wmi: Unknown function number - 5 - 1
[ 1308.784623] acer_wmi: Unknown function number - 5 - 1
acpi -V does not show the device:

Yet, running acpi_listen generates the following when the tablet is rotated:
PNP0C14:00 000000bc 00000000
PNP0C14:00 000000bc 00000000
PNP0C14:00 000000bc 00000000
PNP0C14:00 000000bc 00000000
So, it would seem the device is working and sending data to the kernel/drivers, it appears some config is needed to get it properly recognised and an entry in /dev generated.
Really hoping there is an acpi expert around who may be able to help me get the device properly recognised and configures, ideally, as a /dev/input/js*
Cheers.

There is no need to patch the kernel anymore as current kernels have the acer wmi accelerometer patch merged.
Ensure you have the kernel module acer_wmi loading and then the events should be propogated. acpi_listen should show the events.
Using the code from here: http://www.jezra.net/blog/Python_Joysti … ng_Gobject i have written a little daemon that monitors the accelerometer and automatically rotates the screen based on it's position.
Cheers.
[EDIT] Being a laptop, I am guessing the accelerometer is possibly on the hard drive?? used for shock protection?? So if that is the case, I am not sure you will be able to utilise it in the same way as a tablet's accelerometer. There are articles on the web for setting up hard drive accelerometers in linux. The other consideration you need is that the accelerometer may not be on acpi. It could be on the i2c bus (commonly where sensors such as fan speed, core temps etc are located), in which case you will need the i2c driver to get the accelerometer events recognised in the kernel (ensure i2c kernel modules are loaded). So check exactly how the kernel detects the accelerometer, is it on acpi or the i2c bus?[/EDIT]

Iconia Tab 8 W W1-810 suddenly stopped the auto screen rotation

Hi. I´m havving trouble with my Iconia Tab 8 W W1-810. It suddenly stopped the auto screen rotation and now I can´t find the "enable screen rotation" checkbox. I only get the chance to put it in landscape or portrait but not in auto rotation. How can I enable auto screen rotation again? I will very much appreciate your help.

Thank you, Justin! I tried that but, as I no longer had an automatic rotation checkbox, I couldn´t solve the problem. The solution came through the Acer Chat service. Acer technician Mukesh was very kind and patient, we tried every possible option but the auto rotation option was not available, the only way to get it back was to install the suggested drivers: http://global-download.acer.com/GDFiles/Driver/Platform%20Drivers/Platform%20Drivers_Intel_10.18.10.3643_W81x86_A.zip?acerid=635664922342452308&Step1=TABLET&Step2=ICONIATAB8W&Step3=W1-810&OS=ALL&LC=en&BC=ACER&SC=PA_6 After installing these drivers, I recovered the automatic rotation checkbox and could solve the problem. I am very happy that I could solve the problem and very pleased with Acer´s customer service. Thank you for your suggestion. Kind regards, María Inés.

How to open "All Tabs" from previously shown pages history?

Hi,
How to open "All Tabs" from previously shown pages history. I am not asking about "Reopen from last session". I am asking about how to open all tabs from previous webpage links from a past date from history, currently its allowing me to select each page link manually by clicking it.
Thank you!

Select the first item you wish to open, scroll down to the last, Shift-click that one & all those between should be selected too. Double-click on them & they should all start to open... or you can copy & then drag/paste into a new or existing bookmarks folder.

How to get "tones" tab in drop down menu

how to get "tones" tab in drop down menu

I assume that you are referring to the categories on your iTunes library (?), if you are then go into Edit > Preferences and on the General tab make sure that Tones is ticked
You can also enable the left-hand sidebar on iTunes 11 on a PC via control-S, which then allows you to view the sections of your library (those enabled in Preferences) via that sidebar, and if you have iOS devices they will also show on that sidebar when connected.

It is then up to you to split that string up (search for split string on this forum for methods) into it's individual components.
If the text file contains a standard structure on each line, i.e. it is a fixed delimited structure, then you could use external tables to read the data instead.

How to copy a tab from one tab group to another?

In Tab groups view, drag and drop allows one to move one tab from one group to another. But how to copy a tab?

Press '''CTRL''' while dragging to copy instead of moving.

How much RAM do tab groups use (on average)? Do I need to watch out for how many groups I create?

I may have gone overboard in the creation of Tab Groups. I say this because now my system is beginning to act a bit sluggish. I created 7 groups, two of which have 9 or 10 tabs. Should I pull back on the number of groups I create (as well as how many tab are located within each group). That is: How much RAM do tab groups use. How can I calibrate or understand the trade off between these markers and the amount of RAM they use?

You can see the memory usage on the about:memory page.
You can open about: pages via the location bar like you open a website.

How to change a TAB dynamically to be the active tab?

Hi,
I have a portlet written in Java and registered using a web provider. This portlet exposes a link which drives the content of another portlet through parameters&events.
This other portlet is placed on the same page but on a different TAB (!).
What I want is, when clicked on the link in Portlet1, this changes the content of the Portlet2 (via an event and parameter - that works) AND should change the TAB, so that the TAB which contains the Portlet2 is active and shown.
I couldn't figure out, how to change the TAB with an event or any other way. I can easily change the page through an event, but not to a tab on the same page. Do I overlook something or can I just don't use events for this?
Is there any API function which does changing tabs or getting the tab id or is there any other programmatic workaround to do dynamic tab changing?
If so, can someone point me to a code fragment?
Any help would be much appreciated.
Cheers,
Erik

A work around may be to change the location.href to the url of the tab you want to switch to.
Have you tried that already?

Hi purav,
as Michael wrote, the simulator tab is part of an older VC version. I asked a colleague in the past, he told me that this simulator tab was available in Visual Composer 6, but in the latest version, this tab is no longer in use. There was also a debug button in the task panel toolbar, but this button is also no longer available in the latest version.
