CyanogenMod 9 (CM9) on Scroll Extreme tablet

I’ve had my Scroll Extreme for a few months now, so I figured it was time to break it!

I ran CyanogenMod on a HTC Desire for quite a while and figured that was the mod to go for. CyanogenMod 9 is Ice Cream Sandwich (ICS)

There is plenty of information out there about getting CM9 on a Scroll Extreme, but I didn’t find it very easy to get an overview of what to do and where to get the files. So here’s what I did.

Install clockworkmod recovery

This is used to flash the actual rom images. At this point you cannot install clockworkmod using Rom Manager as the Scroll Extreme is not supported.

  • First download clockworkmod that works with the Scroll Extreme. I used this link – here – more info – here
  • Then I extracted install-recovery.sh and recovery.img and copied them to the Scroll Extreme. I used Dropbox.
  • Then to copy the files to the device and install clockworkmod I followed these steps – here
- Unpack CMW file and copy install-recovery.sh and recovery.img to a directory (eg CWM) on the sdcard on the tablet.
- Open a terminal and become root:
su -- Busybox doesn't have a cp command, so use cat to get the files into
the right directory:

cat /mnt/sdcard/CWM/recovery.img > /data/recovery.img
cat /mnt/sdcard/CWM/install-recovery.sh > /data/install-recovery.sh

- Change the permissions on the shell script and run it:

cd /data
chmod 755 install-recovery.sh
./install-recovery.sh

You should now be able to enter clockworkmod by powering off the Extreme, and powering it back on while holding down the Volume Down button

Get CM9

Now we just need to grab 3 files. I did this by e-mailing the links to the Extreme and downloading directly to the device.

You will need –

  • Suitable CM9 from – here – more info – here
  • 907c compatibility drivers required for the Scroll Extreme from – here – more info – here
  • Google Apps for Android from – here

Flash CM9

I did the following to flash CM9. You may want to erase the device while flashing. I decided to do it at the end.

  • Reboot in to clockworkmod
  • Erase the cache
  • Erase the Dalvik cache
  • Flash the CM9 rom
  • Flash the 907c comparability drivers
  • Flash Google Apps
  • Reboot the device

It took 2 or 3 minutes to start up the first time. With the funky CM9 blue fiery screen displaying for most of that time. Once started the lock screen was still in place and all the apps were still installed. I then did a factory reset from the settings page.

Camera and WiFi still seem to work OK. Now I need to install my apps and do some testing.

Obviously you follow these instructions at your own risk. There’s a real chance you’ll break your tablet  🙂

    Thanks! Summing up the courage to do similar. You’ve been running the mod-ed extreme for a month now, what’s the long term prognosis of CyanogenMod on this device?

    Yes, it’s been pretty good. The tablet seems more responsive generally. I actually lent it to someone not long after upgrading so haven’t seen it for a while! But I’ve not heard they’ve had any problems.

    Hi Matt, I have a couple of scroll extremes in our house and I would love to perk up their responsiveness and reduce the program hanging. How’s the mod been running as I’m quite interested to have a crack at it.

    Yes, it went well. Not noticed any issues and things seem more responsive, especially the long delays that used to happen when the keyboard is actiavted.

    Cheers, Matt
