I finally took the time and updated my “old” Samsung Galaxy S+ (GT i9001) from the Stock 2.3.6 version of Android to CyanogenMod 10, beta 4. I really should have done this earlier. The stock version was getting slower and slower over time without any apparent reason and no update to a newer version was expected from Samsung. It seemed that especially changing cells was wasting CPU like crazy. I always resisted from installing CM because the device is not officially supported and most ROMs I found so far had serious bugs like missing tethering or Bluetooth. The ROM I finally found really works flawlessly and much faster than the stock installation. Everything I tested so far works as expected including Bluetooth and tethering using WiFi and USB.

Of course, as usual with Samsung devices I had to go over several bricks before I finally got a running installation. Also, I ended up being stuck with an endless recovery mode loop caused by Clockwork Mod Recovery, which was fortunately cured by this solution (German) after the second attempt. The only thing left I have to find out now is the battery consumption…

Btw, why are all these people on the android hacker forums so unbelievably brief and pseudo-geeky with their language. Really a pain to read posts and descriptions there…
