Remember always to flash Hard-SPL. If you haven't, then don't flash any of these radios.
- Download and extract the Custom RUU (Rom Updater Utility) in a empty folder on your pc
- Download and extract the radio file (.nbh) in the same directory as the RUU
- Start the RUU and follow the procedure.
Still not sure how to do it? Look Here and Here.
Normally you wont lose any data on your phone, when updating your radio, but make a backup, to be safe... Then you can't blame me. :)
The most popular radios differs from time to time. Just remember a higher version number isn't always better.
What radio should you use? - Read this thread, and try some of the radios out. There is no answer to what is the best, it all depends on where you live and how you use your phone.
Important before you flash... Be care full. If you **** up you might brick your phone...
