If someone really needs to brick their device ... that is VERY easy. Just use dd with corrupt recovery.img and boot.img .... That happened to me and I could return the device to ACER under warranty.
[Acer Iconia A500] AZDR1V3R:
Im on a custom rom so will the adb locations be different?

Can i manually put the system.img and boot.img on the main sd then put the update.zip in the external sd and do it that away??

i just need some help please
[Acer Iconia A500] ggp2jz:
Ok I have no idea what I am doing wrong. I have used two different SD cards trying to install both the Chinese and the German update.zips and I am still getting stuck on the green android with the yellow ! after about a 1/3rd of the yellow bar. I do not know what else to do. After about 2 minutes the system reboots and I get a red secure boot: image lnx checksum fail!
[Acer Iconia A500] ggp2jz:
NM got it working
[Acer Iconia A500] dgsmith90:
Yay! I'm back to stock so I can receive this 3.2 update when it comes out soon enough! Thanks OP. I did have to install the update.zip through CWM, but it worked. Apparently my SD card isn't reading in stock recovery. I am beginning to think the card is going bad because it reads once the device is hooked up and it has gotten corrupted before in my phone even.

New with these things

Hello,

I'm new in this forum, and I would like to ask if some of you could be so kind to make a tutorial for dummies for me. Please.

I bought my Iconia Tab a500 in Shanghay thinking it would be easy to change it to the European way and I'm still sad because I can't use it as I would like to.

I downloaded the files that are in page 1, but afer I don't know what to do with them.

I waited like a crazy guy to the upgrade to 3.1 to appear thinking that being in Spain it would upgrade to the European/USA way but no, it didn't!

Now I have downgrade it to the factory status.

So please if one of you great minds could do a step by step tutorial I would be eternally grateful.

Even if I write more or less correct, sometimes it becomes hard to me to understand technical vocabulary.

Thank with some advance to you guys!!

Hey everyone my Acer Iconia A500 Tab is stuck on power off. It says its shutting down but is never does. So I try to use the update from this guide to restore my tab.

But when I try to install the update.zip and I am still getting stuck on the green android with the yellow ! after about a 1/3rd of the yellow bar. I do not know what else to do.

This is a very old thread..

Not sure why you need this but there are updated repair procedures and fixes..

do a search for timmy dean. his root/ upgrade is a much better solution..

you can post back your issue and someone may be able to better help you . due to multi upload being taken down by the us gov.. most all links in xda are TOTALLY DEAD...

good luck

Completely stock ...

In Canada with 1.016.05_COM_GEN1 ( Kernel 2.6.36.3-00001-gf991e5d )

Can I apply this method to get to 1.141.07 ??

in order to do ADB and SU... is that part of the desktop ADB already or do I have to ROOT the A500 first ??

and thanks... ;)
[Acer Iconia A500] Crsdr37:
This is the USA build so this will give you completely USA stock. Not sure if Acer will push you updates but if you do it. You do need to be rooted
[Acer Iconia A500] themono:
I wonder if anybody has tried this with the New Zealand version... We haven't received any OTA updates at all, so this could be a way to get our tablets back up to where you guys are if it will work on ours...
[Acer Iconia A500] UnicornKaz:
so what are you saying is ... ??

since I'm in Canada, I shouldn't ? incase Acer won't push future updates ??

ODD, I seen report of people buying the device from 1 country while on their vacation...etc... what will happened if they brought the device home to their own country ?? are they screwed ?? I would think not !

Damn Acer !! :D :rolleyes:
[Acer Iconia A500] dr1337:
Everyone, you have to flash the boot.img together with system.img. Otherwise you haven't done anything different from updating the system.img with the Chinese rom.

That's why your WiFi isn't working. The update is patching your incompatible kernel at the wrong locations therefore rendering the new patched WiFi modules incompatible.
[Acer Iconia A500] Crsdr37:
Well there has been speculation around them pushing updates by serial #. If that is the case then your serial is Canadian based thats what I am saying. Now if thats not true then you will just keep getting pushed the US updates.
[Acer Iconia A500] ryutsuke:
Yes actually I was able to get wifi working again. I ended up just taking your suggestion from before and used the 2 .img files which changed my kernel version to simply 2.6.36.3 and now everything seems to be working great so far.

Thanks again.
[Acer Iconia A500] Crsdr37:
this should work on any acer iconia tablet. What it is doing it erasing the boot.img block the flexrom.img block and the system.img block. Basically making it a US iconia. The only thing I cannot at the moment tell you is if you will be offered updates. And if they are they would more than likely be American. If you do get them and they are American they will succeed if they are not American you will be back in the same boat of not being able to update until you get back to your original firmware for your country. :D.
[Acer Iconia A500] Crsdr37:
You are very welcome trust me I was pulling my hair (although my head is shaved)Very hard until I found the solution.
[Acer Iconia A500] dalepl:
Updatr Failed

OK. I tried your steps in the first post. All went well until I went to apply the update.zip file. It says booting recovery kernel image and that is where things go wrong. It comes up and then gives me the big triangle with a yellow exclamation point. Tried rebooting and I get Secure boot: image checksum failed. So what do I do now? Thanks.
[Acer Iconia A500] Crsdr37:
Ok the only reason the update would have failed is if you didnt do the boot image first.

Do not reboot until you do the boot.img and the system.img.

Once those are both pushed to your device then reboot only reboot once they are both pushed. The system image will take around 240 Seconds to push. so wait until that is done. If still not working let me know the reason for the checksum error is because you have 2 new .img that do not match your old flexrom.
[Acer Iconia A500] dalepl:
No, I did push both and in deed, the system.img file did take a while, but I did wait for the # prompt to come back befor rebooting my tablet. As I said, it fails to load the update and now will not boot at all.
[Acer Iconia A500] Crsdr37:
What version were you on before doing this?
[Acer Iconia A500] dalepl:
1.104.022_com_Gen1
[Acer Iconia A500] Crsdr37:
Now you said a # sign came up. Did it show anything else. Also you could try doing a factory reset or doing the chinese update then re pushing these. There is no reason it should not have worked. Did you change anything in your tablet?
[Acer Iconia A500] Crsdr37:
Did you do it through ADB or terminal emulator
[Acer Iconia A500] tomlogan1:
Checksum error

No, I never got past it, just reloaded another that's floating around.
[Acer Iconia A500] Crsdr37:
The checksum error is because you need to do the update zip.
[Acer Iconia A500] dalepl:
I used ADB. It came back and showed the file transfer size and then the # prompt. That is what I am talking about.
[Acer Iconia A500] dalepl:
How do you do a factory reset. The reset button does not help. Also, the tablet was stock except for being rooted.
[Acer Iconia A500] Crsdr37:
Alright the only thing I can rec. To get you back up then try again is to flash either the chinese from or the German one floating around. Then try back from step one. I flashed from the german one.
[Acer Iconia A500] Crsdr37:
Take your SD card out connect a keyboard go into recovery then hit the homekey- use the up and down on your keyboard to factory reset
[Acer Iconia A500] dalepl:
By the way, is the update file supposed to be only 37.9 MB??
[Acer Iconia A500] Crsdr37:
Yes the update is only minor bugfixes
[Acer Iconia A500] Crsdr37:
Let me know how it turns out. Ill help any way I can.
[Acer Iconia A500] dalepl:
Well, at the moment, I am stuck. I have no USB keyboards around. Only a wireless one. I guess I may be returning the tablet in the morning and getting another one. :(
[Acer Iconia A500] Crsdr37:
No here is a fix dl the chinese update put it on your SD card and boor into recovery
[Acer Iconia A500] Crsdr37:
Then you can redo because that is a full system. Restores the whole thing
[Acer Iconia A500] Crsdr37:
Give me a few minutes I have the update.zip i used it will aid you in recovering. With this one you dont have to do anything with the wifi lib modules. :D
[Acer Iconia A500] themono:
Thanks for that. I think I'll wait it out till 3.1, and if that comes out for NZ tablets fine, but if not out at the same time as the US update, then I'll convert mine to a US one and run the risk.

[Acer Iconia A500] Crsdr37:
That makes no sense since that basically a recovery zip. Since its a full system. Have you attempted the chinese zip?
[Acer Iconia A500] dalepl:
Could not find it. Does anyone have an update file of it and/or the 1.104.05 ROM?
[Acer Iconia A500] Crsdr37:
The 1.104.05 from has not been released by Acer.
[Acer Iconia A500] Crsdr37:
http://forum.ppcgeeks.com/acer-icon...-a500-iconia-tablet-full-restore-9-steps.html

Here follow this for the chinese zip. Then follow my instructions to get yourself. Updated so you can receive updates.
[Acer Iconia A500] ryutsuke:
I had a similar issue and mine ended up having to do with the sd card I was using. When I would try to run the update.zip I was using a 16GB sd card and it would fail every time. Then I tried a 1GB stick I had lying around and for some reason it worked fine.

I have an 8GB in mine? Could just be the class of card or brand
[Acer Iconia A500] tomlogan1:
Could be. I noticed when you put an SD card into and Android device it creates Android directories and Lost directories etc. I deleted these from a class 2 32 GB card and that worked. The card is a no name from eBay. Sandisk 8GB class 4 card did not work. 4GB Sandisk class 2 did work with the Chinese update and the EMEA update.

I guess you need a good supply of cards to make it run. When I check for updates, it says my device is up to date as it has from day one! All this tinkering to get back to where I was ten days ago.. Thanks for your help.

Hope you have time to answer.

All the best.
[Acer Iconia A500] dalepl:
A 2GB microSD will work. That is what I used. It must have something to do with the manufacturer and not the size. I do not know how you could verify this without trying a load. The 16GB microSD card I was using worked fine to hold data, but when I tried to use it for updating my tablet, it failed with the triangle with the exclamation point. Anyway, if you do have a problem, try using a different microSD card.
[Acer Iconia A500] Crsdr37:
No it only looks for update.zip not. Img until we have a custom recovery you have to do it the way outlined in the op.

Put them on the root then use something like astro file explorer to move them to SD Card the only thing that should be on external is update.zip
[Acer Iconia A500] Johnny0906:
Oh! you mean put the Zip file in the External SD and the other 2 images in the internal SD Card mem?
[Acer Iconia A500] Crsdr37:
Yes there are folders when u use astro called SD card and external update zip goes in external. Then use something like terminal emulator to push the images.

Any ideas?

[Acer Iconia A500] Crsdr37:
Su is for super user
[Acer Iconia A500] Crsdr37:
Don't boot recovery just hold volume - and power let it auto seek

Sorry im a total noob at this, i have superuser but what am I to do next?
[Acer Iconia A500] Crsdr37:
Adpfter you type su and it prompts for super user then you type each Command the boot.img first then hit enter. Then type the command for system. Your tabket will freeze when the second one finishes you have to force shut down then do the update zip

is there will be any problems if ive already applied flexrom.img from Acer_A500_1.104.02_COM_GEN1, on stock chinese update.zip? or it shouldnt metter?
[Acer Iconia A500] minotauri:
shouldnt matter. i did this.
[Acer Iconia A500] Johnny0906:
Yes typed su first and the boot.img got pushed the system.img isnt done yet, its much heavier i guess thats why.

So am waiting patiently for it to be done and then reboot with power and vol-

Thanks for your help btw, greatly appreciated!
[Acer Iconia A500] tomlogan1:
I always take the easy way out. COPY the commands from the tutorial and then paste them into the CMD screen. That way, you don't have to worry about making a mistake cause the developers test their stuff before they release it to those of us who need their help so much.
[Acer Iconia A500] Crsdr37:
Should like I said take 240-270 seconds
[Acer Iconia A500] Johnny0906:
So you mean after 270 secs i should force shutdown even tho there is no indication that its done?

Right now im still waiting for the system image to be done and screen seems frozen.

Does this mean its done?
[Acer Iconia A500] Johnny0906:
Right now im still waiting for the system image to be done and screen seems frozen.

Does this mean its done?
[Acer Iconia A500] Johnny0906:
Done! It worked! THANKS ALOT!

You need to be rooted. Then you need to accept the super user command on your tablet when it pops up. Then the commands

No I did not see any indication, but I must have waited about 20 min and the screen was frozen so I just assumed it was done and force restarted and did the Power & Vol- update.

You won't see much different you also don't have to factory reset if you were on a us build.

thanks for tutorial everything works
[Acer Iconia A500] dhruvmp:
I think one reason for all the problems may be related to downloading the system.img. The first few times I tried to download it from megaupload, I noticed that the filesize wasn't quite right. I didn't confirm the size, and then after pushing it (dd) and attempting to perform the update (failed with exclamation point) I got the checksum failure.

Just to make sure, could you post some md5 checksums for the files listed in the OP, so we can make sure the files we have are precisely the appropriate size. This is critical when you are talking about flashing these images, as even a few bytes can make a big difference.

Just a noob question, How do I get adb ? I just updated the tablet and get the wifi error on it :( Do I need to start with the Chinese update or just follow the steps on the first page. Please help
[Acer Iconia A500] Crsdr37:
Wifi Modules

You need to have root explorer installed to fix this issue. The reason it occurred is because your system had a different kernel then the update.zip. To fix this Download this file. Open root explorer and Copy the to lib modules from this download and replace the ones in system/lib/modules. To do this when you get into system/lib/modules hit mount as r/w. So you can write if you dont they will not copy and on reboot you will have the same issue. Once you copy these reboot your tablet and see if it fixes it if not then yes follow the steps in the op. But I believe this will resolve your issue :D

Able to overwrite the image and systems files without the LNX error, but now when I reboot holding down the volume, the update starts but about 1/3rd of the way thru, it errors out to the exclamation point in the triangle. I've tried multiple downloads of the update.zip and tried it on two different SD cards.

Any suggestions?
[Acer Iconia A500] Crsdr37:
To better help you please state what steps you took and in what order. The boot.img must be mounted first. Also are you getting any after each mount through ADB or are you using Terminal Emulator please be as specific as possible.

Yay ! I got it working. So I should be set for the upcoming 3.1 honecomp update rgt ? Once again, I appreciate your help man :D
[Acer Iconia A500] Crsdr37:
Ok So what that is telling me is one of two things.

1. You don't have the ADB Drivers Installed Correctly

2. You Don't have USB Debugging on in your device. Which is found under Applications in the Settings menu of your tablet.

It is one of those two items. If you are still having trouble you can use an app called terminal emulator found in the market. You can do the commands from there but just know when you do the system.img the tablet will freeze. So you will not know that the copy is complete. But stated from a previous post that it will be copied correctly. So if you go through this route. Make sure you give your tablet roughly 5 - 7 Minutes before you do the force shutdown to start the update.zip. :D
[Acer Iconia A500] bhageman:
Following the steps to the letter.

Running the China update since the LNX problem this morning

My steps

1.) ADB Shell

2.) SU, get dialog, authorize superuser, #

3.) Mount image, wait for confirmation (16384+0 records in, 16384+0 records out, 8388608 bytes transferred in 3.5 seconds)

4.) Mount system, wait for confirmation (629145600 bytes in 237 seconds)

5.) Power down

6.) Restart holding volume

7.) starts update, progress bar moves to 1/3rd, then goes to error
[Acer Iconia A500] Crsdr37:
You should be perfect for the upcoming release of 3.1!!!!!! :D
[Acer Iconia A500] Crsdr37:
Well someone earlier had this same issue It was his SD card. The only question I have for you is what sizes have you tried and what brand. The other thing you could try is formatting one of them through windows then copying the update zip to it. Also a couple pages back I posted a german release you could try loading that one then do these. Steps. I originally came from that one. Shouldn't matter however which build just an idea.
