Return to "Stock" without deleting data topic

I have Lollipop 5.0 installed on my device but somehow there are modifications in the firmware dir.

Will re-fastbooting it with stock 5.0 and removing the -w make me stock without deleting anything?

[Q] Stock ringtones replaced despite deleting contents of OEM partition topic

Hi,

So I recently got my AT&T Nexus 6 and was eager to rid it of its molestations. I followed the guide on this thread:

http://forum.xda-developers.com/nexu...hread-t2947581

I got to the portion where you delete or rename the OEM partition and use the terminal command to just wipe the whole partition. That's when I got this error:

Code:

---

C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot erase oem
erasing 'oem'...
(bootloader) Permission denied
FAILED (remote failure)
finished. total time: 0.004s

Luckily, another user here had the same problem, and a user named Bodosom had a solution:

Renaming media is sufficient. You can ls /oem after the mount to verify you got the right partition. These two commands undo the above. They may not be needed. / # umount /oem / # rmdir /oem Reboot.

I followed this method to delete the contents of the partition. I didn't bother unmounting the partition. I restarted my device and it worked! The AT&T splash screen was gone and I was happy. That is, until I went to change my ringtones.

I discovered that the alarm and ringtone folder both contained the correct file names for the files, i.e. Titania, etc., but when you played any of the files you got AT&T tones instead. I compared these with my Nexus 5 to make sure I wasn't just crazy. I checked the OEM partition again and it was definitely empty. Somehow, the AT&T files had replaced the AOSP files except for in name. I re-flashed stock android 5.0.1 and the problem persists. To make matters worse, when I try to select a custom ringtone, the filetype is not supported (both .wav and .mp3).

Any idea what's happening here? Is it something with the SIM card? Are AT&T's machinations more cunning than they were at first? Help would be appreciated.

Deleting old data? topic

So I was playing around with different skins to get one to work with Cinema Experience. Seems the Ace skin works OK with it. If I play the movie first, then stop, then do again but wth CE, it's all good.

After playing with the various skins, I uninstalled them. The problem is XBMC now takes up over 1GB of space where as before I did the other skins, it took just over 500MB.

I installed ES File Explorer app, but wondered if anyone here could give me some tips as to where to find what I can delete? Or point me to another post/forum/wiki.

Thanks,
