[TouchPad Q&A, Help & Troubleshooting] whome0:
Similar problems but finally was able to jump from CM9 to CM11(Milaq) version. Just few days of use but looks ok. I was unable to repartition within cwm recovery scripts, fsck command gave failed=4 error no matter what. Decided to perform the hard way everything.

Current software stack, files and system being used was

Windows7-64bit, Java7-64bit

ACMEInstaller3, ACMEUninstaller novacom bootpush apps

WebOSQuickInstall-4.5.0.jar, webosdoctorp304hstnhwifi.jar Java apps

Preware, Tailor WebOS apps

Moboot 0.3.8 boot menu app

ClockworkMod 6.0.4.7 boot recovery app, this is important must be this or newer to understand datamedia mounts

cm-11-20140208-UNOFFICIAL-tenderloin_milaq <- final Android ROM

Additional packages I used during the trial-and-error, you may need them or be without. Im not sure.

ClockworkMod 6.0.1.9 boot recovery app, this is not datamedia compatible but was able to see /cminstall from "webos" usbmedia partition

New cwm was not able to see webos data partition, all it could see was new /0 Android datamedia profile folders. Don't know why maybe mount point problems somewhere in a boot scripts. This game me problems so had finally upload some of the files to this /0 folders using ADB push command.

Partition table after the process, performed in Tailor WebOS application. This table is only for new Android 4 "datamedia" Google use cases.

Android(System) 600MB

Android(Cache) 200MB

USB(Media) 1024MB <- old /sdcard, but A4.4 datamedia don't use it. Leave it to WebOS.

Android(Data) +25GB <- rest data goes to this new data part, my 32GB touchpad had 25GB available

Unused 0MB

Before the rebuild process had to reboot once to ClockworkMod 6.0.1.9 and formatted existing /sdcard partition. It removed filesystem errors and was good to go. Format removed everything including some of the WebOS apps.

* Before anything else run cwm backup command and copy important user files from /sdcard folder to Windows7, copy backup files as well

* Start Palm Novacom ntservice (service name: NovacomD) to enable usb, this service may use startup=manual value.

* Start device to webos recovery (keep VolumeUP during boot), should large usb logo appear on screen

* Remove existing Android, run dos command "C:\Program Files\Palm, Inc\novacom" boot mem:// < ACMEUninstaller

* Run WebOSQuickInstall-4.5.0.jar Java application on Windows

* Find Preware webos application and install, it should go to HPTouchpad device

* Reboot device to WebOS system

* Run Preware application, find Tailor partition utility and install

* Run Tailor and change partitions, you may shrink and enlarge partitions until get what you want. Leave 1024MB for USB(data) partition its used by WebOS. You maybe could shrink it to 700MB but wanted to play safe even if no planning install WebOS apps.

Following steps I cannot remember exactly what I did but am now running CM11 and CWM 6.0.4.7 datamedia enabled apps. You may need to fiddle with /cminstall, /downloads and /0 folders if new cwm boot app cannot see old sdmedia files from "webos" data partition.

* While in WebOS mount usb fileshare to make it visible in Windows7 file explorer, create /cminstall and /downloads subfolders

* Copy moboot_0.3.8-tenderloin.zip and recovery-clockwork-6.0.1.9-tenderloin.zip to /cminstall folder

* Copy recovery-clockwork-6.0.4.7-tenderloin.zip to /downloads folder

* Reboot device to webos recovery (keep VolumeUP during boot)

* Run dos command I]"C:\Program Files\Palm, Inc\novacom" boot mem:// < ACMEInstaller3[/I] to apply zips in /cminstall folder

* Reboot device and choose cwm recovery app from boot menu

* Select Update zip command and choose new cwm.zip from /downloads folder, apply file

* Reboot device and choose cwm recovery app from boot menu

* Use Android sdk ADB tool to push files to device, cwm mount no longer works in win7 because of ext linux filesys in new /data part

* Use adb push <sourcefile> /0/<something>/. dos command to push zips to device folder

* Push copy cm-11-20140208-UNOFFICIAL-tenderloin_milaq.zip and gapps-kk-20140105.zip files to device

* Start device and choose cwm recovery app from boot menu

* Select Update zip command and choose cm11.zip from folder, then select gapps.zip

* AndroidROM and GooglePlay apps are now installed on device.

* Reboot device and choose CM11 from boot menu

* TrebutchetUI may constantly crash, use topright corner pull down menu and Settings/Apps/All/TrebutchetUI and clear cache.

* You may need to reboot back to cwm and clear cache and dalvik cache few times if Trebutchet keeps crashing. Try to choose Settings/Theme/System option if keeps crashing. I had to do this few times before it was happy.

This was the very hard way and am sure streamlined method was available. Anyway this gave me confidence I still have all the apps creating CM install from scratch.
