Are those images from ES file explorer?

Anyway, if you use ES, and try to enable Root Explorer (toggle in Tools menu), it will run a test which will fail after a few seconds (and toggle off root explorer) if app is automatically installed or moved onto SD, so need to move it back to internal storage if Root Explorer function is required. Took a while to figure out why test failed, so I included this note in original post. (Not sure if fails if moved with apps2sd, but result likely the same.)

"With Oct-N weekly updates retained all settings incl. accounts settings and adopted storage encryption key so SD data was retained.

I'm not 100% sure if this will work with any ROM due to secure encryption used . . .

Recently, I've been been doing clean flashes and starting with wiped SD to avoid problems, but previously retained SD data / apps between flashes with OctOs with no problems."

Use adoptive SD storage and enjoy, or continue using apps2sd (if issues with dex files and Selinux Enforcing causing problems with mount script in N [as well as your formatting problems] have been fixed.) PW

OK, since then I have used the phone and when I recieve calls, the only way to end the call app seems to be to restart the phone.

I have searched and it seems this can happen on Lineage OS but a mentioned fix is to make sure the phone app is the default for the phone. I have checked and it is.

Is there another fix that can be applied to fix this?

Thanks!

So, i am trying to get full EMMC.img dump from my Y550-L01.

i can't get full EMMC for now cos internal sd is not having enough size. = no space left on device!

using that command dd if=/dev/block/mmcblk0 of=/sdcard/EMMC.img

if someone know how to change sdcard for external micro sd please tell me

for now using that command : dd if=/dev/block/mmcblk0 of=/sdcard/EMMC.img bs=1000M count=1

i could get a EMMC.img of about 0.9GB i think.

As soon as my device is enough charged, i will transfer img on my pc then will try to upload.

when the people call me they listen me with a low volume ( I use lineageos 14.1-20170702-unofficial )

I format my sd with internal memory of my phone but now the file are on memory of phone and I can't to move file on sd (adopted memory)
[Android Q&A, Help & Troubleshooting] pndwal:
Not quite sure what you mean, but sounds like you haven't yet migrated data to SD. As I mentioned, this will free up phone memory for basically system and system apps only.

Go to settings, storage, SD card, 3 dot menu at top - and select Migrate data to move data from internal to SD.

Then go to Internal storage, Apps, and individually move any apps that have CHANGE button that haven't been moved automatically. Newly installed apps will be installed automatically on SD if developer supports SD installation.

If Devs haven't added 'move app to SD' support for some apps (and you want to move more), you can still move them. Go to Developer Options, select 'Force allow apps on external' in (Makes any app eligible to be written to external storage, regardless of manifest values).

In a standard file explorer (and with usb mtp computer connection) you will now see only your SD card, which is now your phone (user) memory (ie user data partition), and this has changed to the capacity of your SD card. It doesn't show up before migrating data, even though formatted as internal, as user data partition needs to be swapped to it from internal and the migrate data process does this. That's why there is no longer any internal phone memory showing. (It's now freed up for basically system data, system apps, and unmoved user apps.)

Hope this clears things up for you. PW.

[Android Q&A, Help & Troubleshooting] pndwal:
Happy to hear that.

Dont forget, for good results you need a fast SD card. I use 80MB/s SanDisk Ultra 64GB SDXC, but faster would be better.

Also, if Devs haven't added 'move app to SD' support for some apps (and you want to move more), you can still move them by selecting 'Force allow apps on external' in Developer Options. (Makes any app eligible to be written to external storage, regardless of manifest values).

On another device (Lenovo tablet) I still use Apps2SD to integrate system updates into system (convert to system app). Frees up internal memory as updated app as well as original (deactivated) are otherwise retained. [I tried a stand-alone app (System cleaner 2) to do this recently, but it messed up system apps. Went back to Apps2SD for this, and it integrated updates without problems.] I intend to do this maintenance on y550 also when needed. (Apps2SD has other functions still useful to, eg. Fix Device Lag (Trim partitions), etc.) PW.

Fastcharge (for Qualcomm chip enabled chargers) would be great as [MENTION=7782931]sole4ce[/MENTION] mentioned.

Many thanks for efforts. PW

Did update as dirty flash, and can confirm all apps and settings incl. accounts settings and adopted storage apps, files and encryption key (so SD data is accessible), as well as GApps apps & settings, were retained and work properly. Only lost root, so had to reflash Magisk. PW

AudioFX (only works with VLC)

solved

:

I tried AudioFX after flash / root, and can confirm worked with speaker, but not with headset (headphones).

Next, since I use Magisk for SU (root), I installed the following modules (Magisk Downloads) in addition to Busybox for Android NDK:

Audio Modification Library

(Framework to allow seamless integration of multiple audio mods)

***This fixed audio anomalies, and now AudioFX works properly (incl. headset)!

ViPER4Android FX for Magisk v14+

(ViPER4Android module for Magisk v14+)

Now can use ViPER4AndroidFX instead of AudioFX. All works well, and is far more versatile than AudioFX, with myriad effects / controls, incl. extra gain, etc. (Invokes Googles warning 'this app can damage your device' so use with care especially at high volumes on speaker mode, etc.)

Guess you could try flashing these, or alternative files, from TWRP if using SuperSU, but they're designed as Magisk modules, and they install simply from Magisk Manager and work well.

Alarm (It's a problem in the mornings)

No problem on my device (works fine)! :) L02. (???)

[Android Q&A, Help & Troubleshooting] pndwal:
Turns out apparently need Android 5 for VoLTE, and seems Vodafone never updated above 4.4 despite their PR reports of 2015 saying Y550 would support VoLTE.

I installed Magisk module VoEnabler (Experimental - adds settings to build.prop to enable both VoLTE and VoWifi), with the result that when I check phone Tester (dialer, *#*#4636#*#*, tap Phone Information, scroll down) I see

VoLTE provisioned, Video Calling provisioned & Wi-Fi Calling provisioned all toggled on

. (Were all toggled off before installed Magisk module VoEnabler.)

However, when checking IMS Service Status (3 dot menu, top right), I still see:

IMS Registration: Not Registered

Voice over LTE: Unavailable

Voice over Wi-Fi: Unavailable

Video Calling: Unavailable

UT Interface: Unavailable

So seems IMS registration may be the final hurdle to enable VoLTE. Apparently need to replace CSC file with working VoLTE CSC to achieve this according to XDA threads. Also, may need IMS settings in APN (or an IMS APN), but these changes are a bit beyond me at the moment.

Hope this info helps / hope you can help! Thanks, PW.

Tried boot.img version 2 right away, it seems to fix the problem for me (will test further overnight), also perfectly scales from 200-1433MHz so baterry life could be better now (but it was amazing even with the kernel that's in your last rom build).

Have few questions about kernel adiutor settings that might help with battery life even more:

1) is there a reason for 533MHz to have higher voltage than 800MHz?

2) why is cpu hotplug disabled?

3) why is adreno idler for gpu disabled?

4) what are your recommended settings when it comes to governors (cpu, gpu, io)?

Feel free not to answer :D
