I couldn't find a situation similar to mine and I've been searching a while. So I registered here to ask since you all really seem to be on the up-n-up in regard to this awesome little camera.

So I opened up my Z23L Yi 2k (I bought it about a month or so ago) to check out the focus. It turns out that it has 4 glue spots (does not come off easily at all) and looks like it's already been turned. I'll put some photos (dirty iPhone camera) below, looking for your input.

Note position of the clip on the lens cover:

More glue:

Here's a 1080p/60fps video using the autoexec.ash from WaffleFPV shown below


It seems blurry to me, and like the AWB isn't turning off. I'm wondering if I inserted the AWB script correctly (after Sharpness Adjustments).
Code:
# WaffleFPV V8

#--Recording Adjustments--
# 4GB Clipping
writew 0xC03A8520 0x2004
# Sets Bitrate to 25Mbps
writew 0xC05C1EE2 0x41C8



#--Sharpness Adjustments--
# Set auto-whitebalance
t ia2 -awb off
# Coring
t is2 -shp mode 0
t is2 -shp max_change 5 5
t is2 -shp cor d:\coring.txt
sleep 1
# Noise adjust
t ia2 -adj tidx -1 1024 -1

#--Misc. Adjustments--
# Short Beep once script fully loaded
t pwm 1 enable
sleep 1
t pwm 1 disable

What is "coring" and what effect does it have?

I look forward to input from you camera guys, cause I'm totally new to this and trying to understand all these settings.

A couple more videos with the autoexec.ash below each, first with noise adjustment and no coring (table was all 211's), second with neither. I found my darks to be more detailed without the coring, and I like that.

Code:
#Jet-Lee Z23L on 1.2.13

#--Recording Adjustments--
# 4GB Clipping
writew 0xC03A8520 0x2004
# Sets Bitrate to 25Mbps
writew 0xC05C1EE2 0x41C8

#--Sharpness Adjustments--
# Noise adjust
t ia2 -adj tidx -1 1024 -1

#--Misc. Adjustments--
# Set auto-whitebalance
t ia2 -awb off


Then I removed the Noise Adjust script

Code:
#Jet-Lee Z23L on 1.2.13

#--Recording Adjustments--
# 4GB Clipping
writew 0xC03A8520 0x2004
# Sets Bitrate to 25Mbps
writew 0xC05C1EE2 0x41C8

#--Misc. Adjustments--
# Set auto-whitebalance
t ia2 -awb off


These both look out of focus to me, especially if you pause at the end on the flowers and look at the background. I'm about 18" from the flowers. I can't tell that the noise adjustment is doing anything. The glue on the lens is very hard and doesn't seem to scratch, I'm scared of slipping and destroying another part of the camera...suggestions?

Figured out that you're supposed to use a software called Notepad++ to create/edit the autoexec.ash, not just Notepad. That was probably the reason I wasn't seeing any changes to the AWB.

New video here...and I went ahead and attacked the glue with some torch-heated needle-nosed pliers. I drew some lines and dots on a paper, stood it up 5' away (152cm) and took a series of photos with marked rotation on each. Settled on the following setting.

Let me know what you think.
