Highly Functional Unofficial CM9 Build for the Galaxy S2 HD LTE

CM9

Although there’s talk of CM10 around the web, developers aren’t quite done yet getting CyanogenMod 9 on as many phones as possible. With the first release candidate for CM9 released, developers have a great code base to bring an AOSP-derived experience to other devices. One such build is for the Samsung Galaxy S II HD LTE.

XDA Recognized Developer and Retired Senior Moderator dsixda is responsible for bringing CM9 to the highly underrated device. Despite not being the most popular version of the Galaxy S II, the port is very well done, with only a few minor issues. The list of current things working include:

- Wi-Fi
– Adobe Flash
– Play Store
– Vibration
– Hardware acceleration in browser
– Orientation sensor (model AK8975)
– Gyroscope (model K3G)
– Accelerometer (model K3DH)
– MTP
– Audio from speaker
– Video playback
– YouTube (including HD videos)
– USB mass storage
– Compass
– Rear camera (model M5MO) takes photos, and uses flash
– Bluetooth (and A2DP)
– GPS
– Phone
– 3G/HSPA/LTE Data
– SMS send/receive
– Headphone audio
– Torch app
– USB tethering
– Speakerphone
– Wi-Fi hotspot
– Lights on capacitive buttons
– Proximity sensor (model TAOS) for phone
– Ambient light sensor (model TAOS)
– Internal and external (micro) SD card access (Note: Internal SD is under /mnt/emmc, micro SD is ‘sdcard’)
– CPU frequency is being reported correctly as 1512MHz
– Backlight Notification (BLN)
– MHL (compiled into kernel but not tried yet)
– Overclocking

And the very short list of things not working:

- Front camera (model SiliconFile SR200PC20M) – Disabled for now; requires Samsung ICS update or ICS binaries from a phone that has the same sensor (I have yet to find one)

Although the feature list is impressive, this is still labeled as an alpha build. In other words, there may be unreported bugs in addition to the front facing camera. That said, the ROM can definitely be used as a daily driver for anyone who’s craving ICS on the Galaxy S II HD LTE. It should be noted that this will not work on any other device except for the Galaxy S II HD LTE, including any other version of the Galaxy S II. Of course, any developers who want to assist in squashing the remaining issues is more than welcome to do so.
