    for who’s got boot loop,, shut down your device

    • http://www.facebook.com/profile.php?id=572725842 Jon-Terje Bjørnerud

      Nope, still doesn’t work. SE Arc, all other firmwares has worked fine, phone was rooted already and worked well. According to what I can find from Sony this version will infact NOT work on normal Arc. If anyone should happen to find a working solution, please post in this thread.

      Thanks

    • Abhijeet Mishra

      Hi. Your download manager renamed the file to .zip. Just rename it to .ftf and you’re good to go.
