[TouchPad Development] nevertells2:
Do not install CM9 over CM7. Some have gotten away with it and others like yourself run into trouble. Do a clean install, that means running ACMEUninstaller. Here are some instructions I created just for an occasion such as this:

Since the release of CM9, it has become abundantly clear to me that one

needs to do a clean install of the rom to avoid all the little

nagging issues that so many folks are reporting. Whether you are

installing for the first time, upgrading from CM7 or installing

an update of CM9, one really needs to do a clean install.

Since the advent of the official CM9 nightlies, installing

the rom and the Gapps files via CWM seems to be much more

reliable. You still need to wipe the cache and Dalvik cache

before you reboot after installing any rom. If you run into

trouble after an install via CWM, then read on.

Those who know how to do it otherwise and are comfortable with that

feel free to deviate from this document.

For first time installers, you can skip this part. First thing

you need to do is a nandroid backup of your current install and

copy it over to your PC for safe keeping. Next you should backup

your apps using either Titanium Backup or My Backup Root. This will

allow you to restore all your apps after you are done with this

update. If the install goes South, you can always restore your

nandroid backup.

For the first time installers, if you have not already prepared

your PC for this project, you need to download the following:

1. ACMEInstaller2

2. ACMEUninstaller

3. Moboot 0.3.5.zip

4. ClockworkMod.zip(CWM)

5. update-cm-9.0.0-RC0-Touchpad-alpha2-fullofbugs.zip

6. UniversalNovacomInstaller.jar

7. The latest Gapps.zip

The ACME files, Moboot, CWM and the Alpha2.zip can all be found

on the OP for Alpha2 at:

http://rootzwiki.com/topic/18843-releasealpha2-cyanogenmod-9-touchpad/

The universal novacom installer and Gapps files can be found by doing a Google

search on the names above and you will find the download page. I found

the novacom installer here:

http://universal-novacom-installer.googlecode.com/files/UniversalNovacomInstaller.jar

You should download the latest Gapps.zip which

the last time I checked at the link below was 20120317:

http://wiki.rootzwiki.com/Google_Apps

First thing, open the run box on your PC and browse to the novacomInstaller

file. This is a Java executable, so treat it just like any .exe file.

However, since it does not end in .exe, when you browse to find it,

you will have to tell the browser to show "All Files." Once it is in

the run box, click on OK and the Novacomd drivers will be installed,

the Palm,inc folder will be created and the novacom.exe will be placed

in that folder. Next if the ACME files you downloaded are zips, unzip

them both into the Palm, Inc folder which you will find in the Program

files folder. If not zipped, copy both into the Palm, Inc folder. Now

your PC is prepared for installing CM9, so everything applies to first

installers and upgraders from this point forward.

First timers boot into WebOS, upgraders can do the same or boot into

your current install of Android. Connect your TouchPad to your PC

with the usb cable and open Windows Explorer on your PC. You should

see either the TouchPad as a drive, or cm_tenderloin if you are already

running a version of CM9. If you have not already created a cminstall

folder on your TouchPad do so now. Also create a folder named ICS

Install.

Next you need to copy Moboot 0.3.5 and ClockworkMod(CWM) into the

cminstall folder on your TouchPad. Now copy the rom.zip and the

Gapps.zip file into the folder you created named ICS Install. It's up

to you which rom and Gapps file you use if you are installing something

different from what is listed above. If you are copying files to the

Touchpad drive, you now need to right click the drive letter and eject

the drive when you are done. If you are copying files to cm_tenderloin,

you can just close Windows Explorer and both of you disconnect the usb cable.

Upgraders, now you need to run ACMEUninstaller and when it is done, your

TouchPad will reboot back into WebOS. Now both of you need to reboot while

holding down up volume to put the TouchPad into WebOS recovery or bootie

mode. You will know you succeeded if you see a large white usb symbol.

Now plug the usb cable back in and you should hear the PC beep indicating

the TouchPad is connected. You will not be able to see the TouchPad in

Windows Explorer, so don't try. On your PC click "RUN" and type in CMD.

This opens the command window. First timers type in the following in the

command window:

cd/ and press enter. You will see C:\

Now type cd program files and press enter. You will see C:\program files

Now type cd Palm, Inc and press enter. You will see C:\ program files\Palm, Inc

Upgraders, your novacom.exe may be in a different folder, so go browse to that folder.

Both of you enter novacom boot mem:// < ACMEInstaller2 in the command window and

hit enter. After a few seconds, you should see what is fondly called the "Double Penguin" on

the Touchpad. When the install is done, the TouchPad will boot to Moboot. Tap

the volume on the TouchPad to stop the 5 second countdown if you see one. Now

select CWM using the Home button, then Install zip file from SD card and use the

volume rocker to move down to the ICS Install folder. Select that and move to the

Alpha2.zip and select that. Start the install. When it is done, use the go back

selection to go back to the main CWM screen and select reboot.

Once Android is booted up(be patient, it takes a couple of minutes the first time),

play around with the browser, set up wifi, just to make sure your install was

successful. Now reboot back to CWM and do the same procedure to install the Gapps.zip

you copied to the ICS Install folder earlier. You're done with a clean install.

Upgraders, you know what to do, first timers, I hope you have friend around to show

you the ropes or you own an Android phone and already know the ropes. Good Luck!

P.S. I strongly suggest you make a nandroid backup of your new installation right now.

First timers, one makes a nandroid backup using CWM. Boot to CWM, select "Backup and

Restore" and select "Backup".
