I don't remember having stuttering problems, though it was obviously laggy. Now it seems much faster. I would say there is no or barely any lag. Pressing anything, like a app, makes it come up instantly. Don't know if this will change though after using it for a longer period of time. AFAIK there was no lag either when I just bought the G Pad.
[G Pad 8.3 Android Development] Motawa88:
I dont own the g pad yet so i want to be sure that it fits my needs.. I saw in videos(reviews) that when you press the app drawer there is almost a 1 second lag... I know it might be nitpicky, but i cant stand those things.

1. Screen is very dark while booting into twrp, but when twrp starts it is bright again. This began after update from v50018 to v50020.

2. I get exactly the same error. Already got this error in v50018. I might be wrong, but I thought it came up after I enabled write access to external sd card.

Art is working very well but a few of applications have FC(not stock one). I think this aplications are incomatibile with ART mode on.Even if Lg give us a rare update , release stable ROMS.

Well, TRWP stay unlit all the time, but all features work fine, so not worrying at the moment... As for the error, I haven't changed write access or anything at all, so it must related to something else... Hoping next release also fixes the ''Standard Android icon on some LG apps'' issue... ;)

Is this the Kit Kat SD bug I saw mentioned somewhere?

Any Solutions available?
[G Pad 8.3 Android Development] Zeljko1234:
Yes it is. Solution:

1. Using a root-enabled file manager, navigate to /system/etc/permissions

2. Edit platform.xml and find the WRITE_EXTERNAL_STORAGE permission.

3. Add an additional group definition for this permission

<group gid="media_rw" />

4. Save the changes to the file.

5. Restart.

Thank you!

[G Pad 8.3 Android Development] Zeljko1234:
I know, I tested on my tablet ;)
[G Pad 8.3 Android Development] Subtleone:
If this could be done, to fix the gamma issues, that would be fantastic.

I am going to install 18a myself to compare, since I am very curious now. I spent at least an hour playing around with the RGB values in Trickster MOD, comparing pictures in the G Pad (with 20a KK) and my color calibrated monitors, and it was really annoying to see the difference.
[G Pad 8.3 Android Development] Zeljko1234:
Replacing boot.img in 20 with one from 18 in flashable zip should be enough. Or just fastboot flash boot boot.img.
[G Pad 8.3 Android Development] Subtleone:
I will try it. I confirmed that 18a really does have improved color rendition.
[G Pad 8.3 Android Development] id10terror:
Let me know how your test goes, if the 18a kernel does really improve color I can add it to the tweaks in the AIO (All-In-One) tool I'm creating.

Both Kernels are compiled by LG using GCC 4.7, which I thought had native gamma correction, but maybe LG tweaked a couple other things in 18a.

------------------------------------------

On another note, I will be updating the OP later today with a flashable V50020B zip, which is what GB\UK users are getting OTA from LG.

Weird that LG would upload a V50020A version to their servers, but then release a V50020B version OTA a couple days later. Anyways, it will be available for DL in the OP later today.
[G Pad 8.3 Android Development] CromDubh:
Anyone have any ideas what changes might have been implemented between V50020A and V50020B.

Anyone know what the gamma was on 4.2.2? I seem to recall it being about 1.6

This Rom gives me about 2

Others say the 18leak have 2.2

Can someone confirm these numbers
[G Pad 8.3 Android Development] Zeljko1234:
I can confirm last two, not sure for 4.2.2 but at least is 2.0.
[G Pad 8.3 Android Development] Canadoc:
So is 2.0 the corrected gamma or its it 2.2like in the 18 version?
[G Pad 8.3 Android Development] Zeljko1234:
2.2 shows more details in dark movie scenes. Or check with display tester.
[G Pad 8.3 Android Development] NYCguy2020:
Any word if the a18 kernel works on a20?

Thanks!
[G Pad 8.3 Android Development] Canadoc:
Well 20 tests as 2.0 gamma.

Would love to flash the kernel on 18. Can someone make a zip of it?
[G Pad 8.3 Android Development] id10terror:
OP has been updated with link for V50020B flashable zip. I've included the Ext SD Card R\W fix on this one.

I'll leave the V50020a links up for a few weeks in case people need it for whatever reason.
[G Pad 8.3 Android Development] Subtleone:
It works. I was impatient, so I flashed the V50020B KDZ from the LG servers, and tested it. It had the exact same gamma as 4.2.2 (V50010B), which was about 2.0-2.1 (somewhere in between). I then rooted with IOroot25, took the boot.img from your 18a ZIP and flashed it with Flashify, and not only did it boot without any problems, but the gamma is now 2.2-2.3.

I used Display Tester to verify the gamma.
[G Pad 8.3 Android Development] Canadoc:
Could you provide the boot.img. for 18 and 20? Would love to flash 18 and test it out with option to go back if performance suffers.
[G Pad 8.3 Android Development] joshuadjohnson22:
Can anyone provide a flashable zip for the boot.img? I tried this and it soft bricked the device. I'm not sure if the extraction was bad or what. I can try again later but this may get time consuming ;)

Edit: i tried again and it worked, only odd thing is brightness is very weird. 0-80 is very dim but 80-100 gets bright extremly fast. Not a big deal just odd. And during boot it is very dimm, very similar to booting into twrp.
[G Pad 8.3 Android Development] Subtleone:
I threw them into my Google Drive:

018a kernel (gamma 2.3)

020a kernel (gamma 2.0)

The exact steps I followed were:

1) flash the V50020B KDZ file from the LG servers

2) root using IOroot25

3) reboot and flash the boot.img using Flashify

Note: I did not install a recovery before any of this.

Before flashing the 018a kernel I tested the gamma with Display Tester as mentioned above. The sizable difference after flashing was all I needed to see the kernel was working.

---------- Post added at 02:23 AM ---------- Previous post was at 02:13 AM ----------

I had that the when I booted. To fix it, I simply closed my case, and re-opened it and the brightness was suddenly correct at all levels. I should have mentioned it but since it disappeared after this I forgot.

Thank you [MENTION=3210378]id10terror[/MENTION]!

Yesterday I dirty-flashed the v50020a on top of v50018a using TWRP 2.7, and so far so good, even I got my S/N back :)

[G Pad 8.3 Android Development] Indopilot:
First of all sorry guys if this belongs to another thread but couldn't find appropriate one. Today my rooted V500 with TWRP (running android 4.2.2) LG software updater offered me to update to android 4.4.2 firmware 20b(I think it said fw is from 23March), without thinking I agreed so 400+ MB file downloaded and I confirmed immediate update. Unfortunately as I have TWRP instead of native LG recovery, it could not update, booted up into TWRP and that's it. Can't even get back into old 4.2.2 as everytime I click on Reboot to System, it always ends up in TWRP again and again. Is there any way out of this? Can I flash the file automatically downloaded by LG's integrated software updater via TWRP and if so, where is the update file stored?

Many thanks, with kind regards

Tomas
[G Pad 8.3 Android Development] id10terror:
Try this:

Download the flashable V50020B zip from this thread and copy it to a MicroSD. Insert that microsd into your G PAD and boot into TWRP.

Then install the zip from MicroSD.
[G Pad 8.3 Android Development] Subtleone:
I did the opposite. :)

I could not see what was so special about 20B so I reverted to the full 018a, which had no such issues. The only thing missing is QVoice, and I never used it on my tablet.
[G Pad 8.3 Android Development] Canadoc:
Would do that too but hear the 18 had issues with battery drain . Can you confirm
[G Pad 8.3 Android Development] Subtleone:
I would not be using it if it did.
[G Pad 8.3 Android Development] Indopilot:
Thanks for the advice - did that, installation successful, wiped dalvik+cache, rebooted into system but ... surprise ... it rebooted into TWRP again!:confused:

Seems like there's no way to make it boot to the system!
[G Pad 8.3 Android Development] id10terror:
It sounds like there's probably something on your FOTA partition that is signaling the bootloader to boot to Recovery to finish the OTA install. But obviously your Recovery is not the stock one that would perform that function.

Try this, it will wipe your FOTA partition:

Boot into TWRP

Go to Advanced, then Terminal Command

Browse to Folder: /dev/block/platform/mdm_sdcc.1/by-name

Hit Select button

Now in the text field type this and Hit "Go"

dd if=/dev/zero of=./fota

Reboot system

EDIT:

I've also attached a flashable zip this this post to wipe FOTA partition
[G Pad 8.3 Android Development] meanoc:

I've regretted update to 20 and restore backup of 18. Manly because of picture (gamma) quality. Speed is about the same.

It's worth mentioning that it only complains about that for OS upgrades. LG App upgrades work fine. Since there has only only been one upgrade (KK) in its lifetime, I do not consider it a factor. Plus, if there is an improvement sometime down the line, you can be certain it will be flashable soon enough here, with root and recovery.

Interesting. I don't see a difference between 20 and 18 picture quality.
[G Pad 8.3 Android Development] Subtleone:
An easy way to test is to download Display Tester and run the Gamma test. 20a (or b) will have a gamma of roughly 2.0, while 18a has a gamma of 2.2 - 2.3. Not only does this affect the colors, but it affects dark scenes, whether picture or video. Dark scenes will lose detail with a lower gamma value.

That usually means that you have at least one app incompatible with art. Try switch to art just after clean flash.

[G Pad 8.3 Android Development] smsmasters:
Is there a way to force art without starting from scratch?
[G Pad 8.3 Android Development] Zeljko1234:
Yes and no. If you force art, some apps or system apps may force close making your device unusable. In this case you car revert back to dalvik from command line (check link for n7 in my sig) or from some custom recoveries.

Better way is to try to find incompatible apps and find alternative.

systemui stopped working

Hi,

I flashed this rom over my rooted lg g pad (rooted with dalingrin). But when it boots into the system I get the message "systemui stopped working". I can do nothing on my tablet, I can't go into the appdrawer, none of the apps on the front worked... I had to power off with the buttons and boot into recovery with the hardware buttons.

What caused this error ? I have normally a dutch language on the pad, or did I had to wipe dalvik cache and data cache right away after flashing this rom ?
