There has been an update.

Instead of using the model switcher (the blue thing), you can now switch the model
from inside the "Settings" of the DAP.

Spoiler: Images

How to do this?
To do this, go to "Settings", then "Device Settings", then "Reset/Format", and instead
of "Factory Reset" we will now have "Switch Device Model". If you have the device switched
to 1A, the function will switch it to 1Z. Also, if you have the device switched to 1Z, the function
will switch it to 1A. Pretty simple! The process takes only about 1 or 2 seconds, and then the
player will restart. After the restart, you should reinstall the firmware mod, in order to fully apply
the new model's sound signature.


- How do I know the change worked?
It will work for sure. But in order to see the current model of the device, just go to "Settings"
and then to "Certificates", or to "Settings" and "Unit information".

- What happens if I switch the model, but then I don't install the firmware again?
Nothing wrong will happen. The sound might not be the same as if installing the firmware again though.
Feel free to experiment, but the recommendation is that you should install the firmware again after
switching the model.

- How to revert back to stock?
For reverting back to stock, the same thing apply as before - first, make sure you switch to the
original model of your player, and then install the "WM1 Back to Stock" firmware. From there on,
you can install any other firmware you like.

- Do I need to be on version 3.02 before installing the mods?
No, you do not.

- If I am already using one of the two firmware mods, do I need to first switch back to 1A or
to 1Z and then I can install the new firmware?
No, you can just go ahead and install the new firmware.

I had issues with the mids on DMP-Z1 1.02 but no such problems here

Try to combine Z+ and DMP Z1 1.02, for me it sounds awesome

I'm staying with WM1A/Z+ on WM1A

Just tried the same - flashed WM1A/Z+ over 3.0 on 1A without switching - sounds nice!!
And what I did want -vocals now "stand out".
Thank you MrWalkman et al. for all your work, time and efforts!! Kudos!

I hate to be contrarian but does anyone else find the firmware mod a bit sibilant/strong/sharp as a result of it being using firmware version 3.02? Again I apologize for criticizing the firmware so early in it's inception but I just wanted to note my experience compared to my previous firmware which was 3.01 without any mods. I remember experiencing this issue before when switching from 3.00/3.01 to 3.02, where at first the sound signature sounded better with more clarity and resolve and less perceived bass "bloating", but after a while I realized a lot of my music with guitars, cymbals, trumpets etc would sound to a point incredibly sharp and at times overbearing, to a point where I just had to switch back to 3.01.

After doing that I've been on 3.01 for several weeks without feeling any need to change the firmware or the tuning. Now, back to this firmware mod, while to me it does sound excellent, incredibly expanded sound stage and certain micro details are seemingly brought to the forefront in detail, but yet again I am experiencing this sharpness in treble when it comes to high energy music with high pitch guitar solos, keyboard synthesizers, cymbal crashes etc.... Has anyone else experienced this? Anyway my experience is all coming from listening to this firmware mod with my Periodic Audio Be earphones, so it just very well be the synergy of these earphones with the player and firmware mod.

I was thinking of that, I didn't experience what you describe with WM1A/Z+ and player switched to 1Z.

I was thinking of doing the same mod for 3.00 and 3.01 as well, so stay tuned.

Thank you for the reply and considering using 3.0/3.0.1 as an foundation for your mods! I feel all alone in my sentiment about the sharpness of the treble, but whenever I use 3.02, even if I apply sound tuning, that sharpness is always there somehow lol.

Which region 3.02? My stock WM1A was E and it wasn't harsh but quite bright - I switched to J 3.02 and it was more to my tastes with more bass presence.

Music usually sounds better when alcohol is involved; not that I personally know something about it, hahaha

I am using region MX3. I notice that there isn't such a "boost" in treble on 3.01 so I don't know why it was done with 3.02.

Best to state which DAP and Switcher 3.0 WM1A/Z or WM1A/Z+. In your case I'd recommend spending some time with stock Sony 3.02 on region J then comment and as ever headgear will make for a significant differnce. Coming from stock 3.01 differnce will be significant...
