Now that all the Transformer series, tf101, tf101g, sl101, tf201, tf300, tf300g & the tf700 run Android 4, Ice Cream Sandwich, (aka ICS), some users have experienced nothing but joy with the update.
Sadly, some users have experienced varying issues, however. In an attempt to clear most of these up in one hit, here is what to do. Hopefully this advice will clear most of any problems that you might be experiencing. The normal "disclaimers" apply. This information is provided in all good faith, however, you perform any of these steps on your own responsibility.
If you haven't done the update yet then follow these steps FIRST (as originally suggested by Leeshor).
1. Update all apps7
2. Backup your tf using Google, the appbackup utility & an external backup storage (pc, microSD, cloud, external HD, usb flash drive)
3. Do a cold boot - this WILL NOT wipe any data from your tf (process linked in my signature, below)
4. Perform the update
5. Do another cold boot, then start to use ICS
NO UPDATE AVAILABLE?
Go to Settings - Applications - All - DMClient - Force Close then Clear Data.
Then go to Settings - Applications - All - CMClient - Force Close then Clear Data.
Settings - About - Check for Update.
If you already have ICS, but for some reason cannot get a new firmware update automatically, follow a similar process to that above. In ICS, however, the menu names are fractionally different, so the process reads...
- Cold boot (process linked from my signature)
- Go to Settings - Apps - All - DMClient - Force Close then Clear Data.
- Go to Settings - Apps - All - CMClient - Force Close then Clear Data.
Settings - About tablet - System Firmware Update - Check Update.
There are guides linked below, and some other sticky threads in this section that will help you to get orientated. Most, if not ALL "how do I do xxxxx" questions have already been answered, so please read before asking again.
When you first start to use ICS follow these steps
1. Visit the market to check for updates - there are ICS related updates for Adobe Flash Player and G+ for example
2. Realise that not ALL apps will be compatible with this new version of the OS. The overwhelming majority of problems will be caused by this type of app incompatibility. EG Dolphin for Pad browser has never developed beyond the beta version issued for Honeycomb. It has issues under ICS.
3. If you get an app incompatibility, then whatever that app is, follow these steps...
a. Force close the app
b. Do a hard reset
c. Uninstall the app
d. Reinstall the app
e. Do a hard reset
f. Try the app again.
If the app still causes problems, you will just have to wait until it is updated for ICS.
If your app is a "system" app and cannot be uninstalled, try these steps suggested by Detection which relate to the email app here, but the logic would apply to any other system app.
"If it still has problems, you could try Settings > Apps > All > Find either ASUS Email or Email (Depending which one is causing problems) > Clear Data > Clear Cache > Force Stop > (This will probably delete any emails and / or accounts attached and you may need to set them back up again) Reboot the TF and Open and set back up your email clients if needs be."
THE FINAL SOLUTION
If nothing else works, and your tf was working normally before the update, then you will need to perform a FACTORY DATA RESET and start again. In ICS this is found under, SETTINGS - PERSONAL - BACKUP & RESET.
Remember to back up your personal data prior to doing this as this process will wipe your tf of all data and restore it back to as if it had shipped pre installed with ICS.
Having done the reset, try your tf for a while with only the stock apps to ensure it is working well. Then install apps one at a time and check their compatibility with the new OS. If you find an incompatibility that you cannot work around, uninstall the app and perform a hard reset before installing any others. Follow this process methodically and you should be able to resolve any issues that are not hardware related requiring a return to Asus.
SOME users are reporting "reboot loops", "random reboots", "faster than normal" battery drain since the update. MOST users are not experiencing this. The fix for these issues will vary between owners, but in almost EVERY case, the issue has been fixed by checking wifi sleep settings, or sync settings for a particular app, or a wallpaper app that is incompatible, or a widget that is incompatible, or a social network app that is incompatible, or a launcher that is incompatible - you get the idea
One reported fix is to change the setting in the TegraZone app. By default under ICS it checks for new items every 12 hours. Changing this to "off" has fixed some reboots for some users. This setting has been changed in the most recent version of this app - back to a default of "OFF", just check that before continuing
In each case, rectifying the settings or uninstalling the app (ie as suggested above) has rectified this. In SOME cases a factory reset has been necessary - IF your apps are still present after you think you have done a factory reset - you haven't done it correctly, so do it again. A factory reset will WIPE all data & not leave you with anything other than a stock tf with Asus apps. It has been suggested by some that performing three Factory Resets has cured their problem. It may not make much sense, but if you are doing one, you may as well take the extra 6 or 7 minutes and do three.
Another issue reported by some, is an issue with some "system level" apps such as Maps & Mail. It would appear that removing your Google account & then adding it back resolves this one.
Always ensure that the home screen is displayed prior to allowing your screen to turn off. It has been demonstrated that leaving a live app displayed onscreen when the screen turns off - automatically, or manually - causes some systems to reboot.
Installing an app which prevents your device from sleeping has also proved a viable workaround for many. The current favourite app is WakeLock. You can read more about this, here...
This is not a small update. This is a full replacement & upgrade of your OS. It has proved remarkably successful for the overwhelming majority of users. That said, in a major update like this, some issues are a certainty. If you are affected, it can be frustrating - BUT it is not insurmountable - patient and methodical application of the points listed here WILL solve 99.9% of the problems reported.
Don't panic. Don't get frustrated & good luck.

MAY 22 2012 Update -
Sorry for the delay, tried not to die from pneumonia last week after a relapse. I will start answering general questions again today and forwarding CSR events to the Service Team. Good news is that we have hired a full time employee to assist our Tablet owners in the Android centric forums. His name is Tien Phan and he is available here under the user name Asus_USA. He is part of our new Customer Loyalty Group and will be taking over forum coverage and assisting our valued customers. I will still be around, especially to handle technical problems and coordinate with Engineering until Tien is completely up to speed. However, as always, if you run into a problem that is not solved by our Service Group please feel free to contact me.
MAY 31 2012 Update -
We are working on another release with updated code from NV/Google. I will be in Taiwan next week to discuss this version and once a beta is available we will release it to a small group of testers. So far, this updated code based has worked extremely well on the TF201/TF300 in beta testing. As soon as I have an update it will be posted.
June 11 2012 Update -
We received additional code enhancements from NV/Google while I was in Taiwan last week. We will create a beta update shortly for testing and hopefully the next firmware update will occur in the next two weeks. I/O and Thread priority changes are the top two items and will address ANR and Sleep issues, however, still testing various application loads as some applications do not want to play nice with thread overrides.
