Do you have a recent backup that you can reload? If so, I would do that and get it functioning again. Then try the download and reinstall again... it sounds like it got corrupted. Maybe just try re-downloading it and reinstalling it again? Or try installing the previous OS - which version are you trying to install? And which did you have on the phone prior to this?
i dint have back up, i download the OS for both multi-language and standard, but it stuck at reconnecting to JVM, i download the 7.1.0 but i cant tell the prior version of the OS, i also used BBSAK and JL_Cmder but it could not connect to my phone
i did something new, i tried the downgrade OS, 7.0 and it start to show light on the screen with something like its processing (but not the hour glass) and i thought if i can get the OS 6 may be it will revive the phone, i tried all the other OS (latest and downgrade) that shows me when i am updating the phone fails, but just the 7.0 made a bit progress. please help me with the link for OS6
