If your 3.1 OTA update fails check the log file >>>>

[robdroid]

If your 3.1 OTA update fails… there’s a paper trail as to why it failed.


On a rooted A500, using RootExplorer open (as text file) /cache/recovery/last_log. You will see some error(s) near the end of the log file. In my case it mentioned file missing /system/app/DTG.apk. That was the Documents To Go app I removed when I first bought my A500. So I needed to put that app back in that folder in order for the update to complete.


So I downloaded the previous system update file “Acer_A500_0.000.00_1.016.01_COM_GEN1” at: [OTA] Full Package and Update - xda-developers

Then decrypted it with the decryption tool (just run the .exe file and load the file you just downloaded from the previous step and hit "decrypt") from: [DEV][APP] Acer update decrypter - xda-developers

Then with Windows Explorer opened the unencrypted zip file, opened the “update.zip” file (takes a few seconds to unzip), browsed to /system/app/ and copied then pasted the DTG.apk file to a folder on my hard drive.

Using WiFi File Explorer on the A500 I then copied the DTG.apk file from my computer back to the /system/app/ folder of the A500.

Once that was done I tried the 3.1 OTA update and this time it worked perfectly.

So… look at that log file in /cache/recovery/ it will tell you what you need to complete the 3.1 update successfully.

PS- once 3.1 updated, you need to re-root with the new 1.2 root tool for the A500 as Gingerbreak no longer works : [HOWTO] Root for stock HC3.1 - xda-developers

Looks like the updater cant find the update file itself (?)... which is odd as heck!!!!
I am probably going to be of no help with this, but if you haven't tried more than once, then redownload the update over the air and try again.
(I am assuming you are not trying some hacked way of installing the update and are only using the official OTA release).

Looks like the update download was corrupt, you just have to try again....

Mine failed first time too. I didn't take a particularly sophisticated approach since I'm not rooted. I removed my SD card and then retried the install. it worked fine. HOWEVER, there seems to be a growing problem with wifi post-3.1.

 

[Comicfan]

I'm rooted.. re-installed all the system apps that I deleted, tried to install it 4 times and didnt work. the system reboots and then the screen freezes on a red danger triangle. after I hold the on/off button for a few secs I can turn on the iconia normally.
my log says: E: failed to verify whole-file signature...

hmmmm..

[Comicfan]

You absolutely need to return all the original stock apps to your tablet for the update to work
I pulled a few thing off mine and the update failed but as soon as they were put back on it work like a charm .

You're running "itsmagic!" from XDA which is changing your file checksum and causing the update to fail. You need to check over there (XDA) on how to remove it.
You have to be stock (root is OK) to update to 3.1

Exact same thing happened to me, if someone could help here that'd be great...

I might try to check the system logs with Eclipse in USB Debug mode, just in case there would be some clue.
