Hi guys, I've gone through many tutorials about radio flashing, but none of them shows us how to backup our radio currently in use.

Is there a way to perform a backup of our stock radio?

Wah, reply so fast~

No need ka? What if in the case of sending back for warranty, we need to restore back the stock ROM etc, the stock radio is also necessary right?

In XDA http://forum.xda-developers.com/showthread.php?t=877295, I saw this version of the radio Radio_12.28b.60.140e_26.03.02.26_M. However my stock version is Radio_12.28b.60.140eU_26.03.02.26_M (note the U).

I also read somewhere that the U is applied by our phone, so that version will be usable?

My idea is that if possible I will like to backup my own. And so far there seems to be no solution yet =/
