I apologize for the lengthy post, but I've been going down uncharted territory the past few days and I'm afraid I'm headed for trouble. So before I reach the point of no return, I'm asking for help. My info first: Sprint S4, rooted with Clockwork 18.104.22.168 recovery installed. I have not been able to install any custom ROMs as of yet (so I assume this means I'm still on the stock ROM.) Currently running 4.3 on the phone. I've been using ROM Manager and Titanium Backup Pro. ROM Manager has been the root of problems. Even though I have the app configured to use external SD storage for backups, it keeps backing up to my device - which now has no storage space left (20kb). I've tried deleting the ROM Manager backups (except for my original backup in case it was needed), but it doesn't free up any space after rebooting. I have not been able to locate where ROM Manager stores the backups in order to try a manual delete. I see a couple of directories under the "storage" folder on the phone that are labeled "sdcard0" and "extSDCard", but don't dare mess with them without knowing what I'm doing. My first issue is how to locate and delete the backup files so I can regain space on the device. BTW: My SD card has over 40GB free space available - so plenty of room there. I'm just concerned that if I delete the only backup that is still listed in ROM Manager, I may be deleting a backup I need later if I unroot. Or is my Titanium Backup (of "userapps + system data") enough of a backup? Additionally, my phone has downloaded the OTA update that I have not installed because I'm rooted. I tried using instructions on how to delete the downloaded update, from another thread, but file names don't match and again - uncharted territory for me. So I need help freeing up space on my phone, deleting the OTA update, or possibly just returning to unrooted mode. Not sure of my best options. Thanks for any help and again, I apologize for the lengthy post.
