Guys this is on hyperdoid, Don't know about others but i have other backups of different roms as well will give it a shot.
Is it the reason why most of the chef's says you should shutdown instead of reboot to avoid data lose? :-s
All the partition are given RW access.
What to do? Please help

didn't anyone find it strange or its just me?

I don't find this strange.
I wouldn't worry about it. If it does bother you, remount them R/O?

ok thank you for response.
Then why OEM ROM Builders always set system partition as RO?
Isn't it if you have sudden crash or phone fall down there is more chances that you will lose data or be left with corrupted partitions?
Regards

Nevermind Fixed it myself.
Now i am sure i won't be having any bad effect on my System partition as its read only during the phone operation (after booted up).
I will ask Tytung to add this in his kernel.

Dice Player and 720p Playback

Hi
Hoping to get judder free 720p playback on the streak I installed Dice Player and patched the libOmxVdec.so file on the streak
I had to use various ADB guides as my ADB knowledge is non existent
http://diceplayer.inisoft.co.kr/news-and-tips/howtoremovenexus-1h264codecrestrictions
http://forum.xda-developers.com/showthread.php?t=1170541&page=2
http://forum.xda-developers.com/archive/index.php/t-914244.html
http://www.droidforums.net/forum/droid-hacks/14349-adb-push-permission-denied.html
Eventually it file seemed to go in OK, but I can't see any difference - 720p Playback is still juddering via Dice Player
It's highly likely with my limited ADB knowledge that I messed the transfer up
So if anyone has got this to work and finds the playback with dice player has improved can you please provide a walk-through on how you did it
Many thanks

libomxvdec.so is not magic wand.
you can play only H.264 [email protected] not 4.0/4.1/5.1
If you patch properly, your stock player can play 720p [email protected] MP4 file.

Hi
I must admit I was hoping for a magic wand
Since I found it so difficult to patch - I may not be patched properly
I'm a total newby to adb - If a walkthrough is available I love to get a hold of it
Many thanks

Wifi Tether on Google store Pixel (Verizon Sim and build)

Here is what worked for me:
(I am on a Pixel from the Google store using a Verizon sim on build NDE63X / bootloader unlocked / rooted / on EX kernel)
While the phone is turned on (NOT in download mode), open minimal ADB and push these commands:
1.) adb shell
2.) su
3.) mount -o rw,remount /system_root
4.) cd /system_root/system/
5.) settings put global tether_dun_required 0
6.) echo net.tethering.noprovisioning=true >> /system_root/system/build.prop
7.) adb reboot
Also note, adb reboot command did not reboot my phone, so I did it manually and it worked out fine.

...

This works!
thanks I can confirm this works!

You didn't do those two commands right. There should be a space between "cd" and "/" in the first one, and you forgot the stuff after the ">>" in the second one.

When I enter su it says permission denied. Please help.

Linux chroot +++ No connectivity

Hi @all,
I'm experimenting with a Ubuntu chroot on my Moto G5 with LineageOS 14.1. I tried to use the same setup as on the HT6 from HomTom, where I used a partitioned SD card. First partition as Fat32 and second partition as Ext4. Now I recognised that the kernel can manage Ext4 as well as Fat32. Both of the partitions are mounted by default. So I tried to remount the Ext4 partition without the noexec, nosuid etc. options. It worked so far and I created the groups for the network access and added my user to this groups.
But still no permission to the socket...
I think the possible matter is the SELinux security policy. Is this a possible reason for no connectivity?
If yes, does anyone know how to solve this?
Or if someone knows the reason for my problem, could you please tell me?
Thanks in advance for your help!

Access A20 System Partition via ADB

Hi,
I have a galaxy A20 with a broken screen.
I managed to boot into recovery and adb detects the device which is rooted with magisk.
But when i try the "su" command after "adb shell", it returns:

I have to access the system partiion in order to enable USB debug by editing default.prop and /system/build.prop.
My intention is to mirror and control the phone screen from my PC.
Can anyone give me a direction?
Thanks
