You need the correct bootloader to fix the brightness issue. Official cm 12.1 and official TWRP require the kitKat bootloader to have the correct screen brightness.
[G Pad 8.3 Android Development] tmihai20:
I am still on the KitKat bootloader. I flashed the zip containing the Lollipop Rom, specifically not to flash the bootloader that comes with Lollipop.
[G Pad 8.3 Android Development] Deltadroid:
You seem to be on the jellybean bootloader if you have brightness troubles with official cm12.1. Don't forget that the bootloader has recently been changed for cm12.1.

MicroSd dismantling

For a solution, I will try this out.Because this bug is very annoying, I use some applications on the MicroSD and many times they are inaccessible, then I in options (dismount the drive and then active again), but it's annoying to doing it.

Hopefully LG will launch a 5.1.1 update (at least) for our Tablet, because I think he's great with me in all studies. Thanks again for the tip! I plan to get this ROM or if I'm going to Custom.

Stock ROM with Bug in MicroSd and Custom ROM with other Bugs rss .... Woe is hard! My tablet is new, not yet tested any custom, just get out of 4.4.2 to 5.0.2, like the Stock ROM, but bug in MicroSd is too boring. The Way will be waiting for a maturing of custons and / or the release of LG 5.1.1 if it ever will launch.

I'm almost that to AOSP ROM 5.1.1 or CM12.1 same. I even think that resumption of bugs are less boring than MicroSd rss.
[G Pad 8.3 Android Development] fishears:
I'm about to release a kernel for this rom. It'll be in two flavours: one stock with bug fixes, one with extras and tweaks. I'll look at getting an emmc fix included before I publish.
[G Pad 8.3 Android Development] tmihai20:
[MENTION=3325155]fishears[/MENTION]: that would be awesome. Leave a link for the thread and I will test it :D Also, is there a flashable zip with the 4.4.2 bootloader? My tablet may be on the Jellybean bootloader, I am not sure. I know for sure that I don't have the Lollipop bootloader.

Sorry. I do also have a SD card inside. I NEVER had a disconnect of the SD card?

My pad is rooted and stock 5.02 korea rom.

So i cant understand. Is that depending on the SD card? If i read you post i would suggest not?
[G Pad 8.3 Android Development] Deltadroid:
It can depend on the type of sdcard. The problem occurs mostly when downloading files while the device is sleeping. Sleep mode seems to cause the emmc driver to remount the card when it's being written to. Since kit Kat, the emmc driver has changed to remount the card if it thinks the card is hung up, which is the problem.
[G Pad 8.3 Android Development] juniorhxcx:

[G Pad 8.3 Android Development] tmihai20:
I had sporadic unmounts even with the eMMC fix included in the test kernel from [MENTION=3325155]fishears[/MENTION], I mean sometimes the SD card would not get unmounted, sometimes it would get unmounted a lot. [MENTION=3325155]fishears[/MENTION] said he has not the unmounting issue, but that he also doesn't have any mp3s on his SD card. I noticed that the media indexing process ate the most battery and I thought I should check my mp3s for errors. Hundreds of them had errors, from not so serious errors to really serious ones. These could lead to unounts. Check your SD cards from errors on the filesystem level and the mp3s with this software http://sourceforge.net/projects/mp3diags (it has Windows, Linux and Mac versions). Be very careful, the program does not back up the originals unless you modify the settings (backup of original files is disabled by default).

This also applies to any bad files on it that the system may scan for. Check your files, especially the media ones. I never had any issues with the files on Windows, but Winamp and any media player is known for better handling of any bad files.

Well, it did not seem to help. My tablet does not see the 2.4 Ghz AP when it is emitting on a channel above 11, even with the changes in that file. I did not know why it did not have Internet connection.

Edit: I have been given another solution by [MENTION=3325155]fishears[/MENTION]. I uncommented this property in the same ini file and now my tablet connects to AP on channel over 11. I have changed it to GB. I think both properties have to be modified to get it working.

hi, installed your rom, every thing works perfect and i love it,

but i have a problem with SD Card, it does not mount at all !

when i installed AOSP-Marshmelow rom , the sd card worked just fine, so im sure my SD and G Pad are ok, but in this rom, when i insert the same SD, says SD inserted, and then nothing, i cant do any thing in the settings, and the SD is not recognized any where else.

I have done this , an formating the sd, and factory reset. and i have permission to write on external sd but

my problem is that the SD card is not recognized at all, some thing wrong with drivers i think.

when i installed AOSP-Marshmelow rom , the sd card worked just fine, so I'm sure my SD and My G Pad are ok.

but in this rom, when i insert the same SD, says SD inserted, and then nothing

in the Storage Setting the "mont sd card" and "erase sd card" are Grayed, and the SD is not recognized in any file manager, even on the pc.

PLZ guide me to fix it, i love this lollipop and i dont like the aosp marshmellow and kitkat.
[G Pad 8.3 Android Development] fishears:
Have you tried with my Custom kernel? There is something different in Marshmallow because my exFAT SD doesn't work on it even though the dev added exFAT to his kernel. But that card works with on this Rom. Can you access the card on another device (pc, laptop)?
[G Pad 8.3 Android Development] shayanagha85:
No i have not. Where can i find your kernel and what's the method of installation? And Is your kernel compatible with this lollipop version?

Yes, the the SD is completely ok, and works with other devices such as PC, and its fat32.

Update: i tried changing the format of SD to exFat, and still no luck.

I'm on android v 5.0.2 , Kernel 3.4.0 , Build LRX22G, Software version:V50030a
[G Pad 8.3 Android Development] fishears:
My kernel thread is here and yes, its built for this rom. Try Custom 1.0.6 - you need to flash it with TWRP. I'm not saying this will fix your problem with FAT32, I have a more up to date exFAT driver, but it might.
[G Pad 8.3 Android Development] shayanagha85:
[MENTION=3325155]fishears[/MENTION]

Thanks for your reply. I'll give it a try and post the result

Update : I used both kernels but none of them fixed the problem. still does not recognize SD, i tried both exFAT and FAT32.

is there anyway that i send you a log or something that you could recognize my problem? i searched every where but it seems that no one have had this problem

and one thing, i noticed that in my TWRP v2.8.7.1 also i can not access the External SD,and i cannot mount it there too. is it normal or not?

I would try removing all partitions on the sdcard using a pc and creating a new fat32 partition.

Just formatting the sdcard is not enough. There could be an issue with the boot sector. Recreating the partitions is the only way to be sure.
[G Pad 8.3 Android Development] roirraW "edor" ehT:
Please don't post about the same problem in multiple threads. Reformat your SD card from the running Android OS.
[G Pad 8.3 Android Development] aicjofs:
Yes I see he pulled in my commits. You can mount and access exfat fat card but not through the normal Android way.

For the Marshmallow it's because the vold system doesn't know what exfat is. Here is an example from omnirom for what LG probably did https://github.com/omnirom/android_system_vold

Notice google has entirely changed it in 6.0 https://android.googlesource.com/platform/system/vold/+/android-6.0.0_r26

See how there is now a folder "fs", that volume.cpp has been replaced, etc. At least makes changes to blkid, vdc and vold in system/bin

There is more to it though because I couldn't even mount it with ext4 or f2fs which IS suppose to be supported. Anyway not the thread to be talking about another ROM, but the issue was enough I came back to LG lollipop.
[G Pad 8.3 Android Development] GalaxyKnight:
Now im also affected to the SD problem

Yes. I get a failure yesterday. My tablet told me: SD card unmounted. Data error. Please check your SD card.

Some files could not be played.

So format it with the tablet. Recover datas and have a look, if it works?

Any alternatives to the system who would work like a charm as this one?
[G Pad 8.3 Android Development] GalaxyKnight:
So what i found out.

The SD card was really damaged. This is not a problem of the FW here.

Try the stock kernel from LG (there is a link in the first post). I think this is an issue related to the LG kernel than to fishears' kernel. I had the unmounting on KitKat just as badly as it is happening now.

[G Pad 8.3 Android Development] ASW1:
Has anyone tried this rom with xposed alpha?

I wonder if the same issues arise as apparently happen with the G2 (LG weather/smart cover)
[G Pad 8.3 Android Development] Deltadroid:
For testing purposes, maybe you could provide the rom with selinux enabled and I can give you a small flashable zip to disable it.
[G Pad 8.3 Android Development] Skin1980:
The selinux is disabled in the command line of the boot.img. Later if i find the time i will repack the img with selinux enabled so you can test.
[G Pad 8.3 Android Development] Deltadroid:
I've created a flashable zip that edits the boot command line for any kernel. So, users can disable selinux on any kernel.
[G Pad 8.3 Android Development] Skin1980:
then you can enable it easily ;)
[G Pad 8.3 Android Development] Deltadroid:
Well, the script appends to the boot command line, but not remove things from the boot command line.

So, it's easier to disable selinux than it is to enable selinux.

Take a look at this:

https://www.androidfilehost.com/?fid=95916177934554559

Note: this script is only for bumped kernel images. It is not for loki kernels.
[G Pad 8.3 Android Development] ckret:
why do you want selinux enabled?
[G Pad 8.3 Android Development] Deltadroid:
Selinux protects the system from application that try to do things that they shouldn't. I suppose the main reason is security. I can understand disabling selinux on custom ROMs because there are bugs, but the stock Rom should not have problems with this.

For example, a web page could exploit your web browser and make it do things it should not. Selinux prevents this.
[G Pad 8.3 Android Development] Skin1980:
I have seen, IMHO you should build an aroma - based zip that let you choose your preferred option. If i can suggest, bump the kernel instead of loki.
[G Pad 8.3 Android Development] Deltadroid:
Yes, I want to make a flashable zip that converts a loki kernel to a bumped kernel, but I need that python script converted into a standalone c application to do that.

I just read your comment again and I misunderstood. Yeah, aroma could be used to combine the loki and bumped selinux zips into one. Good idea.
[G Pad 8.3 Android Development] Skin1980:
You can use the code from my G3 sharpening script to bump directly in recovery:

Thanks! I will take a look.

[MENTION=2174433]Skin1980[/MENTION]

I'm looking at livebump.sh and I'm trying to understand why the script unpacks and then repacks the boot.img. I don't see any changes happening to boot.img in that step. It seems like mkbootimg is using the exact same values as when the kernel was originally created.

Is mkbootimg modified?

The only change I see happening to boot.img is from this piece of code, but it can't be that simple to bump a kernel.

echo "Bumping the boot.img..."
printf '\x41\xA9\xE4\x67\x74\x4D\x1D\x1B\xA4\x29\xF2\xEC\xEA\x65\x52\x79' >> /tmp/image_bumped.img

Also, I've noticed that you "clean" the boot partition. Is that also required? I've never seen any kernel installation scripts do that before.

Thanks very very much!
[G Pad 8.3 Android Development] Skin1980:
When you dump the kernel with dd you get the boot.img + unused space. The magic bytes must be placed after the last used page of the boot.img. Unpack and repack is the easyest way to remove that useless bytes.
[G Pad 8.3 Android Development] Deltadroid:
Oh! So if my current script already unpacks and packs it, then all I need is that little snip of code I posted. Awesome!

Do I need to clean the boot partition?

Probably not, but i prefer to clean the partition before the flash.
