Later I installed Xposed installer and it tried to install Xposed framework but it didn’t support my device. The install/update button was greyed out. So I went on XDA and found this alpha version of Xposed installer that works with Android L from here http://forum.xda-developers.com/show….php?t=3034811
Then I downloaded "xposed-v78-sdk21-arm.zip" from the same thread and flashed it using TWRP. And rebooted. It rebooted straight to recovery. I needed to check if the newly flashed zip file worked and I could finally install Xposed Framework but it won’t reboot to system. So I decided to clear cache. I selected just the cache partition and swiped to wipe. But it was stuck showing "wiping cache". It was wiping cache for a long time but normally just wiping cache doesn’t take that much time. So I pulled the battery and rebooted to recovery. Then I wiped Dalvik cache. Still didn’t boot to system. But the cache was clear. So I tried a factory reset (the first option that shows in TWRP on the wipe menu) after I pulled my sim cards and external SD.
And now whenever I turn on my phone it shows the boot logo (Symphony logo, my phone’s brand) and then goes to TWRP splash screen and the display blinks after a few seconds and again its the TWRP splash screen. Means when it was supposed to show recovery options (Install, wipe, backup etc) the splash screen started again. And blinks again and splash screen again and so on untill I pull the battery. I know my phone is not bricked because it turned on (or is it?). As it is stuck at the TWRP splash Screen, It cant go into recovery mode where you have Install, Wipe, Backup etc. options.
What do I do now? Experts, please help the noob
