Hi guys,

I would like to ask few things as I am not sure now, please. What are the correct permissions (and owners & groups) for:

/system/xbin/zipalign (owner:root group:shell perm 0755 ?)

/system/xbin/sysro (owner:system group:system perm 0755 ?)

/system/xbin/sysrw (owner:system group:system perm 0755 ?)

/system/etc/init.d (owner:root group:shell perm 0755 ?)

/system/etc/init.d/93zipalign (owner:root group:shell perm 0755 ?)

Because I have found in some ROMs /system/etc/init.d is set to 0777 and same with sysro & sysrw & zipalign (some ROM have different owners and groups). Thank you for your help.

Having exactly the same problem although my Tab does not reboot but turns black (not 100% black, a very dim backlight still active). Doesn't do anything until I force shutdown by holding the power button.

Currently on nightly 21/04 CM 12.1 using Nova Launcher. But happened with 18/04 aswell.

Also tried RedKernel to fix the problem --> no change.

The gapps that I'm using actually replaces the stock launcher with Google's launcher. Maybe that is why I'm not having problems with the black screen anymore. I had the black screen also when I first installed 12.1 after a factory reset. The problem seems fixed now that the stock cm launcher is replaced with Google's launcher.

Black screen on LG v500 running CM 12.1

This post is related to "http://xdaforums.com/lg-g-pad-83/development/rom-official-cyanogenmod-12-1-t3086899/page9" thread (but as I'm new in this forum, it does not allow me to post in that thread.

I'm using CM-12.1-20150509-NIGHTLY-v500, and I'm experiencing these "black screens".

For me, it usually happens when I'm typing something (no matter whether in Evernote, nor Inbox, nor posting a message in the Clash of Clans).

And the only way to regain the screen is rebooting the tablet.

I'm using the Swiftkey Keyboard (v5.2.2.124).

The oldest build I can recall that these black screens weren't happening is CM-12-20150304-NIGHTLY-v500. Perhaps this might give a hint on what to diff against.

[G Pad 8.3 Q&A, Help & Troubleshooting] Cal:
As you don't say much about your system...I will say you will possibly get rid of the black screen freezing by loading this kernel: Rick Roll's #15 found here: https://www.androidfilehost.com/?w=files&flid=19557

Later versions of RR's seem to not 'fix' the issue, but this #15 has fixed it for me. For a bit of info, I'm running the nightlies (now on 2015-05-11 with RR's #15) So far, so good for me. :)

EDIT: all you need to do is boot to recovery and load the #15 zip and reboot system on TWRP.

Error flashing zip

Is there any detailed guide on how to install CM12.1 for the v500? No matter what I try, I keep getting "assert failed: run_program("/system/in/loki.sh") == 0", and the tablet won't boot afterwards. Flashing infected's version of CM12.1 works fine.

For example, I followed the steps outlined here.
[G Pad 8.3 Q&A, Help & Troubleshooting] Deltadroid:
You need to downgrade your aboot partition to 4.2.2. If you look in this forum, there is a thread about switching bootloaders from 4.2.2 to 4.4.2. If you flash one of those, it will downgrade aboot to the correct version. Then you can flash official cm.

Thanks, using one of those bootloaders was the last piece I missed.
[G Pad 8.3 Q&A, Help & Troubleshooting] joe776:
Another problem: I cannot unmute notifications. The volume slider is at 0 and the tablet only vibrates. Pushing the volume buttons just displays the sliders, lets it vibrate, but doesn't change anything. These are the relevant lines of the logcat when I try to adjust the volume:

W/AudioService(1062): stream was not muted by this client
E/AudioService(1062): Could not get client death handler for stream: 5

I had the same problem with infected's build. Anything I can do about it?
[G Pad 8.3 Q&A, Help & Troubleshooting] Deltadroid:
If a factory reset does not fix the problem,

I would try going back to stock with lg tool and then root the device over again. It sounds like something is wrong with one of your partitions and going back to stock should reset it.
[G Pad 8.3 Q&A, Help & Troubleshooting] joe776:
Hm, after a complete wipe in recovery, I can control the volume of notifications, however the tablet does not vibrate anymore when I mute it. I can switch between (vibrate, no control) <-> (control, no vibrate) by exchanging the settings.db of com.android.provider.settings with the one before the backup. Something in there might be weird?

The setting under Buttons "Volume keys control ringtone volume" never seems to work for me. The buttons always control notification volume.

Maybe I'll try resetting it completely with the LG tool and starting over, but for now this is just a minor annoyance, and I don't want to restore all settings and apps.

You can flash the latest nightly with either bumped or loki recovery. It just looks nicer if both the kernel and recovery are bumped so you won't see that secure boot error, depending if you boot to recovery or boot to system.

Bump vs not bump

I need help.

I am stuck to the latest non bumped cm 12.1 build.

I am using rr kernel 15 to avoid black screen bug.

I use latest non bumped twrp.

I use latest modular gapps.

I use deltadroid script to get rid of the warning boot msg and to set permissive mode.

I want now to upgrade to latest cm build which is bumped. But I still want a kernel like rr15 to avoid black screen issue. Also I am interested in the latest Bluetooth fix zip.

How I must proceed?

First reboot into recovery and install the bumped twrp.

Then reboot into recovery.

Then wipe cache and system and dirty flash latest cm build.

Then install gapps.

Then install Bluetooth fix

?

But If I do so, I will experience the black screen issue and it seems rr15 is not bumped.?

Also what about bootloader?
[G Pad 8.3 Q&A, Help & Troubleshooting] Deltadroid:
Ok. If you still need to use red kernel r015 to fix the black screen, then you can't upgrade aboot to 4.4.2. The installer for r015 uses the older loki method that isn't compatible with the 4.4.2 aboot. Although, you can still update your bootloader, and not update aboot. I have posted 20D firmware package that will not update aboot, since you have already downgraded aboot to work with loki based ROMs. You don't have to reinstall gapps because they automatically get restored every time you dirty flash a rom update. You do not need to clear cache or anything else.

1) reboot to recovery

2) install 20D firmware that does not update aboot (because r015 installer still references loki) http://xdaforums.com/showthread.php?p=57851987

3) install latest bumped twrp by [MENTION=4517918]jsevi83[/MENTION]

4) reboot to recovery

5) install latest cm12.1 nightly build

6) install red kernel r015

7) flash script to convert loki to bumped kernel (because r015 is not bumped) https://www.androidfilehost.com/?fid=95916177934554766

8) flash Bluetooth sepolicy fix

9) reboot to system

Except I am still unable to use BT connection due to instability issues when both WiFi and BT are used. In that case BT reboots every 30sec. ?
[G Pad 8.3 Q&A, Help & Troubleshooting] Deltadroid:
Hmm. Have you tried using only the latest nightly build and the Bluetooth patch, without redkernel?

Did you unpair your Bluetooth devices and add them back?

Also, a factory reset might fix the wifi/bluetooth problem.

But, if nothing fixes the Wi-Fi/bluetooth problem, then that could mean your device is not compatible with the 20D modem.img. In order to fix that, you would need to flash a different version bootloader that has a different modem.img. I could help build you a package that will only flash modem.img and nothing else, but I would need the modem.img from somebody.

Another option is to use LG tool to go back to stock. That would install the stock modem.img. Then, you could update your bootloader, but not update modem.img.

Edit: here is a different 4.4.2 bootloader 20B with different modem.img from Great Britain. This will not update aboot.

[G Pad 8.3 Q&A, Help & Troubleshooting] Deltadroid:
It sounds like a rom issue, but I have not experienced this behavior. There are not many complaints about this either, which makes me think the problem is specific to your device. Strange behavior like this could also have to do with firmware in the modem.img I was talking about. The modem partition contains files for wifi, Bluetooth, and sensors. I don't know what region you bought your device, but perhaps try using a modem.img from or close to your region.

What is best kernel for CM 12.1?

I'm having this weird 'Screen rotation' issue(not locking in Landscape mode). In order to fix this many advised to flash a custom kernel. I tried Red.Kernel with AOSP ROM available (android version. 5.1.1) and it gave me a black screen. May be it is non-compatible with CM 12.1 equivalent. So if I flash this kernel with the CM 12.1 nightly will it cause any boot issues?

Still no positive result :(

Since after your reply and few other's I decided to try a custom kernel with the CM 12.1 . I used the Red Kernel for v500. Also to avoid any other issues like the 'Black Screen' apart from the 'Landscape rotation' issue I followed the the steps in this post[http://xdaforums.com/showpost.php?p=61045545&postcount=26].

[G Pad 8.3 Q&A, Help & Troubleshooting] Deltadroid:
Try flashing this ROM from the link below. The stock kernel in the ROM from the link below requires the 4.4.2 bootloader (which I assume you are already using with red kernel). Use the stock kernel that comes included with the ROM. Do not use a custom kernel with the ROM from the link below.
