My last phone was a SGS3 LTE Variant (GT-I9305T) and was running an unbranded 4.3 German stock ROM. Inadvertantly, MTU size was set on this phone to 1500 which meant I could use the phone to tether, and most importantly connect to Xbox Live.
Since upgrading to the SGS5 (SM-G900I) with a stock firmware (Telstra - Australia) - MTU is now standardized at a much lower size (presumably by the carrier). Whilst I can tether and browse on connected devices, I can no long connect to XBL without taking my SIM and placing it in my old phone.
Can anyone suggest a way to manually increase this size on my new SGS5?
