Stock ROM for honor 7

Hi,
I'am a user of honor 7 (PLK-UL00)
I tried to root honor 7 but after the last step i.e to install SuperSU and then reboot your system,
My phone got stuck in boot loop then i started searching for a solution and found that i should install
another version for SuperSU which i did and that made my phone to always boot into bootloader.
Then i again went to hunt for a solution , I got that i had to install a stock ROM for my phone .
When i searched for stock ROM available for my phone i got ROMs available for only PLK-L01
So the question is that is it OK if i install PLK-L01 stock ROM in PLK-UL00 phone.
I'm struggling since a week ,immediate response will be appreciated
Thank you

"Android is upgrading: Optimizing apps" every time I reboot

My phone's Java VM was originally dalvik when in Kitkat. I did a firmware upgrade to lollipop, and now my Java VM has changed to ART. I mentioned that because I've read people say this is the cause for the "Android is upgrading: optimizing apps... Estimated max time xxx seconds".
So I want to know how to get rid of this optimizing thing because this takes a lot of time when booting up.

How does /etc/mixer_paths.xml TinyAlsa ctl/path routing work?

/etc/mixer_paths.xml is apparently related to TinyAlsa (https://stackoverflow.com/questions/...xml-in-android).

The file can be edited to reroute or alter audio. "adb root && adb remount && push mixer_paths.xml /etc/"

The file starts with a series of default parameters. I assume each corresponds to a hardware/ALSA value or rounting preference.

Code:

---

    <ctl name="Voice Rx Device Mute" id="0" value="0" />
        "id" is used when multiple controls appear under the same name. It's like an indexing scheme.
    <ctl name="Voip Mode Config" value="12" />
    <ctl name="SLIM_0_RX Channels" value="One" />
    <ctl name="SLIM_0_TX Channels" value="One" />

---

Then there are a series of profiles, which override default parameters.

Code:

---

    <path name="headphones">
        ...
        <ctl name="HPHL DAC Switch" value="1" />
        <ctl name="HPHL Volume" value="20" />
        <ctl name="HPHR Volume" value="20" />
        <ctl name="RX1 Digital Volume" value="82" />
        <ctl name="RX2 Digital Volume" value="82" />
        <ctl name="COMP1 Switch" value="1" />
    </path>

---

I observed that changed "RX1/2 Digital Volume" changed the output volume. "HPHL/R Volume" had no effect.

Some paths include an inner "path name=" tag. I assume this inherits settings.

Code:

---

    <path name="voice-line">
        <path name="voice-headphones" />
    </path>

    <path name="voice-headphones">
        <path name="headphones" />
        <ctl name="COMP1 Switch" value="1" />
        <ctl name="HPHL Volume" value="20" />
        <ctl name="HPHR Volume" value="20" />
        <ctl name="RX1 Digital Volume" value="78" />
        <ctl name="RX2 Digital Volume" value="78" />
    </path>

---

Now the kicker... What do path names mean?

For example, "headphones" obviously means headphone port, and "speaker" means speakers.

However, there are literally hundreds of speaker, headphones, headsets, handsets, mic, sidetone-iir, tty, etc... How does Android choose which path to enable?

If I'm trying to decrease headphone volume (for earbuds), which settings do I have to change? "headphones" only, or some unknown set of options?

I noticed an interesting <path name="ADSP testfwk">... What could that mean?

A Google search took me to http://www.perkel.com/x/snd_soc_msm . Searching `snd_soc_msm` took me to https://android.googlesource.com/pla...sm/snd_soc_msm... The log link references "mako" (Nexus 4), not my Nexus 5X (this is the first commit the file appears). Additionally, the file is not available in "master" branch (replace the hex with master), as apparently libalsa was removed.

usb connector flap for z3 [copper variant]

Hi folks, the soft pad on my usb flap (copper z3) has gone completely and the flap is almost useless now.
I was looking for a good replacement (if not original). Could someone (who has already bought) guide me the best place to buy the same?
