Samsung Galaxy S May Benefit From Nexus S Radio

Difficulty:
2

With the recent news that the Samsung Galaxy Note i717 could be hacked to work on T-Mobile’s HSPA+ network, many inquisitive and adventurous users on XDA began to wonder if other devices could benefit as well. XDA Forum Member pwneman looked into what other Samsung devices had compatible radios and found that the Nexus S i9020a for AT&T uses its radio hardware much the same way as the Samsung Galaxy S i9000, and to a limited extent, the Samsung Captivate. Flashing the devices with the Nexus S radio image not only worked, but seemed to yield noticeable benefits (at least on the i9000).

So I found out that the Nexus S radios are indeed compatible with our device. I downloaded some of the hot radios for the Nexus S (KB3 and KF1) and opened them up and found that the Nexus S uses radios (similar to how the captivate/galaxy s uses modems). So I just renamed the radio.img from the Nexus S radios to modem.bin, placed it in an existing cm7 modem package and flashed it via CWM (ICS).

I reboot and get a constant 5 bars of signal. My signal hasn’t dropped from this 5 bars of signal in the last 10 hours (usually it fluctuates from 5 to 3 bars). HSDPA speeds are pretty fast as well. I got speeds of 560 kb/s DL at 3 bars of signal and 140 kb/s Upload. I’ve never ever gotten that high speeds.

If you fancy giving this a shot, and have taken all the necessary precautions like donning your own designer tin-foil hat, proceed to the Galaxy S thread to get started. You can also give it a try on the Captivate, however there have been reports that the 850 MHz band may not work after flashing and that connectivity may be a bit sporadic.
