Thanks for the info. i had made my own pre-rooted firmware including recovery to keep the recovery.
I have NOT ODEXED my device. DSPmamager was the last mod i flashed and it works perfectly. 7 days later i enterd recovery mode and it still works but few weeks later recovery mode stopped working and my phone is having problem for no reason.
well' i don't know if Z3 have the same recovery issues as The XZ , looking at the logs you attached there're 3 log files (and other non-log files), 2 of the logs only contain data and the 3rd is empty, the 1st file shows normal behavior of you installing the dsp mod , it mounted and unmounted normaly ...
also the 2nd file showing you making a backup and also it mounted and unmounted normally ... so no error appear on those logs.
when you 1st posted i thought you had XZ (my mistake) so i advised based on that, but now i know its a Z3C , and with what you're describing on the last post it appears that our recovery Issues are different , the issue we're facing that the recovery is unable to mount system therefore unable to flash, from what you're saying you're issue is not being able to enter recovery? am i right?
to know what problem the recovery has i need to know what the problem is
& a log that shows the problem. anyways, if you're unable to access recovery my only suggestion is to install the official recovery (download it from the OP) for your device (install the installable package from computer) , on [NUT] website there's a specific version for your device . try to mount and unmount or flash or back up things and if there is an issue create a log and share that... you can also try to uninstall the recovery before installing it again (check the OP) .
regarding the app optimization,( i'll explain it simply), Odex is the default state, which means the apps on your device are packaged in a specific way the requires 2 files tje apk file and an odex file that exists on a folder named "arm" with the apk, so you're already odex unless you Deodexed your rom before flashing it, and if only you used prfcreator to get a rooted rom with recovery , you have a odex rom , Now, the mods have Deodexed app, which are unpckaged and require only the apk to run, some mod creators add a script to there mod to delete the arm folder, but from reading your log file , the dsp mod doesn't do that it only extracts files, so you need to know (ask the developer of that mod) which original files his mod replaces with a deodexes apk .
From your log this doesn't seem to be the case < the mod didn't replace any apk that i can see but it did replace some other files shown below
Code:
mounting system
updating system files
minzip: Extracted file "/system/app/DSPManager.apk"
minzip: Extracted file "/system/etc/audio_effects.conf"
minzip: Extracted file "/system/etc/audio_policy.conf"
minzip: Extracted file "/system/lib/soundfx/libaudiopreprocessing.so"
minzip: Extracted file "/system/lib/soundfx/libbundlewrapper.so"
minzip: Extracted file "/system/lib/soundfx/libcyanogen-dsp.so"
minzip: Extracted file "/system/lib/soundfx/libdownmix.so"
minzip: Extracted file "/system/lib/soundfx/libreverbwrapper.so"
minzip: Extracted file "/system/lib/soundfx/libvisualizer.so"
minzip: Extracted file "/system/vendor/etc/audio_effects.conf"
unmounting system
Done!
also shown on the log that this mod is originally for Jelly beans not Lollipop (i don't know if it was updated) , so the files it replaces although might work will be different from the LP ones, and this might be whats is causing the issue, if you're sure it's not, all you need is still get recovery working and clear Delvik.

Can someone check if the md5 checksumm is ok?
I just downloaded the versions of xperia zr new several times and I always get a wrong checksum.
I wondert why rooting and installing of dualrecovery gets wrong and now I checked md5 checksum with MD5Checker and I get a wrong number. Maybe this is the reason.
I rooted with dualrecovery for xperia zr my smartphone well before and now, when wanted to go to Android 5.1 it wont work. I get back to Android 4.4.2 with flashtool and want to root it like before, but it says wrong adb files or so. So right now I dont have root anymore.
I will root und install dualrecovery under windows 10, but I dont think this is the reason for fail. Tried same on laptop of my wife under windows 7 and same probleme there.
for ZR on LP 5.1.1 you need to implement the fix on
this post Or wait for an updated Official version.

Hard to say what was going wrong without any logs.
If it happens the next time, please provide the logfiles mentioned int the first post
well m8, he actually provided some logs
Here 
but i can't see any problem in them, you could check them, you're surely better than me on this .
