I have been facing an issue of slow gprs on my Samsung Galaxy S3 SHV-E210K due to edge network and HSDPA network not being shown while gprs is connected(instead, G and 3G are shown). The internet speed has dropped to as low as 1/6 of the original (which I get on my Nokia C5 phone).
I have a strong feeling that if I convert this korean version of Galaxy S3, I will be able to solve the problem. Please help me converting it completely to international version like Galaxy S3 I9305 because the configuration is exactly the same.
I dont know how to root, how to install custom rom, where can they be found. But a step by step guide will surely help me a great deal. I have heard that this is the best site for all the android forums. Please post the complete solution as soon as possible.
