[Q] Stuck at boot screen after TWRP asking if I want to install SuperSU
I have to think I'm not the first to be in this situation but my searches didn't turn up anything that looked familiar.
I rooted the stock phone and installed TWRP 2.6xx a month or two ago with no issues. Everything's been running great and I decided it was time to make another backup using TWRP.
After a successful backup I wiped dalvik and cache out of habit and went to reboot -- TWRP said I was not rooted and wanted to know if I wanted to install SuperSU? This question was unexpected since I'd been rooted for a long time, and I decided to just say yes. The phone rebooted and stopped at the Samsung Galaxy S4 boot screen. I did up-volume reboot to recovery, but it seemed to hang at the TWRP blue screen -- I later discovered it will eventually get to the menu after a minute or two of the blue screen. I tried wiping cache and dalvik again and rebooting -- every time I try to reboot now it asks if I want to install SuperSU -- whether I say yes or no seems to make no difference -- I've tried both several times. Every time it hangs at the Samsung boot screen, or it takes forever to get to TWRP if I'm booting to recovery.
I've tried wiping cache, dalvik and data with no improvement. I finally tried formatting data, but again no improvement. I also tried restoring my backup several times and wiping cache and dalvik but still stuck.
I prior to today's problems I'd used TWRP a number of times and I don't recall it asking the SuperSU question, so I am thinking that is the key to this problem, and I'm wondering if anyone knows what it means?
